GNU GENERAL PUBLIC LICENSE
Version 3, 29 June 2007
Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The GNU General Public License is a free, copyleft license for
software and other kinds of works.
The licenses for most software and other practical works are designed
to take away your freedom to share and change the works. By contrast,
the GNU General Public License is intended to guarantee your freedom to
share and change all versions of a program--to make sure it remains free
software for all its users. We, the Free Software Foundation, use the
GNU General Public License for most of our software; it applies also to
any other work released this way by its authors. You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
them if you wish), that you receive source code or can get it if you
want it, that you can change the software or use pieces of it in new
free programs, and that you know you can do these things.
To protect your rights, we need to prevent others from denying you
these rights or asking you to surrender the rights. Therefore, you have
certain responsibilities if you distribute copies of the software, or if
you modify it: responsibilities to respect the freedom of others.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must pass on to the recipients the same
freedoms that you received. You must make sure that they, too, receive
or can get the source code. And you must show them these terms so they
know their rights.
Developers that use the GNU GPL protect your rights with two steps:
(1) assert copyright on the software, and (2) offer you this License
giving you legal permission to copy, distribute and/or modify it.
For the developers' and authors' protection, the GPL clearly explains
that there is no warranty for this free software. For both users' and
authors' sake, the GPL requires that modified versions be marked as
changed, so that their problems will not be attributed erroneously to
authors of previous versions.
Some devices are designed to deny users access to install or run
modified versions of the software inside them, although the manufacturer
can do so. This is fundamentally incompatible with the aim of
protecting users' freedom to change the software. The systematic
pattern of such abuse occurs in the area of products for individuals to
use, which is precisely where it is most unacceptable. Therefore, we
have designed this version of the GPL to prohibit the practice for those
products. If such problems arise substantially in other domains, we
stand ready to extend this provision to those domains in future versions
of the GPL, as needed to protect the freedom of users.
Finally, every program is threatened constantly by software patents.
States should not allow patents to restrict development and use of
software on general-purpose computers, but in those that do, we wish to
avoid the special danger that patents applied to a free program could
make it effectively proprietary. To prevent this, the GPL assures that
patents cannot be used to render the program non-free.
The precise terms and conditions for copying, distribution and
modification follow.
TERMS AND CONDITIONS
0. Definitions.
"This License" refers to version 3 of the GNU General Public License.
"Copyright" also means copyright-like laws that apply to other kinds of
works, such as semiconductor masks.
"The Program" refers to any copyrightable work licensed under this
License. Each licensee is addressed as "you". "Licensees" and
"recipients" may be individuals or organizations.
To "modify" a work means to copy from or adapt all or part of the work
in a fashion requiring copyright permission, other than the making of an
exact copy. The resulting work is called a "modified version" of the
earlier work or a work "based on" the earlier work.
A "covered work" means either the unmodified Program or a work based
on the Program.
To "propagate" a work means to do anything with it that, without
permission, would make you directly or secondarily liable for
infringement under applicable copyright law, except executing it on a
computer or modifying a private copy. Propagation includes copying,
distribution (with or without modification), making available to the
public, and in some countries other activities as well.
To "convey" a work means any kind of propagation that enables other
parties to make or receive copies. Mere interaction with a user through
a computer network, with no transfer of a copy, is not conveying.
An interactive user interface displays "Appropriate Legal Notices"
to the extent that it includes a convenient and prominently visible
feature that (1) displays an appropriate copyright notice, and (2)
tells the user that there is no warranty for the work (except to the
extent that warranties are provided), that licensees may convey the
work under this License, and how to view a copy of this License. If
the interface presents a list of user commands or options, such as a
menu, a prominent item in the list meets this criterion.
1. Source Code.
The "source code" for a work means the preferred form of the work
for making modifications to it. "Object code" means any non-source
form of a work.
A "Standard Interface" means an interface that either is an official
standard defined by a recognized standards body, or, in the case of
interfaces specified for a particular programming language, one that
is widely used among developers working in that language.
The "System Libraries" of an executable work include anything, other
than the work as a whole, that (a) is included in the normal form of
packaging a Major Component, but which is not part of that Major
Component, and (b) serves only to enable use of the work with that
Major Component, or to implement a Standard Interface for which an
implementation is available to the public in source code form. A
"Major Component", in this context, means a major essential component
(kernel, window system, and so on) of the specific operating system
(if any) on which the executable work runs, or a compiler used to
produce the work, or an object code interpreter used to run it.
The "Corresponding Source" for a work in object code form means all
the source code needed to generate, install, and (for an executable
work) run the object code and to modify the work, including scripts to
control those activities. However, it does not include the work's
System Libraries, or general-purpose tools or generally available free
programs which are used unmodified in performing those activities but
which are not part of the work. For example, Corresponding Source
includes interface definition files associated with source files for
the work, and the source code for shared libraries and dynamically
linked subprograms that the work is specifically designed to require,
such as by intimate data communication or control flow between those
subprograms and other parts of the work.
The Corresponding Source need not include anything that users
can regenerate automatically from other parts of the Corresponding
Source.
The Corresponding Source for a work in source code form is that
same work.
2. Basic Permissions.
All rights granted under this License are granted for the term of
copyright on the Program, and are irrevocable provided the stated
conditions are met. This License explicitly affirms your unlimited
permission to run the unmodified Program. The output from running a
covered work is covered by this License only if the output, given its
content, constitutes a covered work. This License acknowledges your
rights of fair use or other equivalent, as provided by copyright law.
You may make, run and propagate covered works that you do not
convey, without conditions so long as your license otherwise remains
in force. You may convey covered works to others for the sole purpose
of having them make modifications exclusively for you, or provide you
with facilities for running those works, provided that you comply with
the terms of this License in conveying all material for which you do
not control copyright. Those thus making or running the covered works
for you must do so exclusively on your behalf, under your direction
and control, on terms that prohibit them from making any copies of
your copyrighted material outside their relationship with you.
Conveying under any other circumstances is permitted solely under
the conditions stated below. Sublicensing is not allowed; section 10
makes it unnecessary.
3. Protecting Users' Legal Rights From Anti-Circumvention Law.
No covered work shall be deemed part of an effective technological
measure under any applicable law fulfilling obligations under article
11 of the WIPO copyright treaty adopted on 20 December 1996, or
similar laws prohibiting or restricting circumvention of such
measures.
When you convey a covered work, you waive any legal power to forbid
circumvention of technological measures to the extent such circumvention
is effected by exercising rights under this License with respect to
the covered work, and you disclaim any intention to limit operation or
modification of the work as a means of enforcing, against the work's
users, your or third parties' legal rights to forbid circumvention of
technological measures.
4. Conveying Verbatim Copies.
You may convey verbatim copies of the Program's source code as you
receive it, in any medium, provided that you conspicuously and
appropriately publish on each copy an appropriate copyright notice;
keep intact all notices stating that this License and any
non-permissive terms added in accord with section 7 apply to the code;
keep intact all notices of the absence of any warranty; and give all
recipients a copy of this License along with the Program.
You may charge any price or no price for each copy that you convey,
and you may offer support or warranty protection for a fee.
5. Conveying Modified Source Versions.
You may convey a work based on the Program, or the modifications to
produce it from the Program, in the form of source code under the
terms of section 4, provided that you also meet all of these conditions:
a) The work must carry prominent notices stating that you modified
it, and giving a relevant date.
b) The work must carry prominent notices stating that it is
released under this License and any conditions added under section
7. This requirement modifies the requirement in section 4 to
"keep intact all notices".
c) You must license the entire work, as a whole, under this
License to anyone who comes into possession of a copy. This
License will therefore apply, along with any applicable section 7
additional terms, to the whole of the work, and all its parts,
regardless of how they are packaged. This License gives no
permission to license the work in any other way, but it does not
invalidate such permission if you have separately received it.
d) If the work has interactive user interfaces, each must display
Appropriate Legal Notices; however, if the Program has interactive
interfaces that do not display Appropriate Legal Notices, your
work need not make them do so.
A compilation of a covered work with other separate and independent
works, which are not by their nature extensions of the covered work,
and which are not combined with it such as to form a larger program,
in or on a volume of a storage or distribution medium, is called an
"aggregate" if the compilation and its resulting copyright are not
used to limit the access or legal rights of the compilation's users
beyond what the individual works permit. Inclusion of a covered work
in an aggregate does not cause this License to apply to the other
parts of the aggregate.
6. Conveying Non-Source Forms.
You may convey a covered work in object code form under the terms
of sections 4 and 5, provided that you also convey the
machine-readable Corresponding Source under the terms of this License,
in one of these ways:
a) Convey the object code in, or embodied in, a physical product
(including a physical distribution medium), accompanied by the
Corresponding Source fixed on a durable physical medium
customarily used for software interchange.
b) Convey the object code in, or embodied in, a physical product
(including a physical distribution medium), accompanied by a
written offer, valid for at least three years and valid for as
long as you offer spare parts or customer support for that product
model, to give anyone who possesses the object code either (1) a
copy of the Corresponding Source for all the software in the
product that is covered by this License, on a durable physical
medium customarily used for software interchange, for a price no
more than your reasonable cost of physically performing this
conveying of source, or (2) access to copy the
Corresponding Source from a network server at no charge.
c) Convey individual copies of the object code with a copy of the
written offer to provide the Corresponding Source. This
alternative is allowed only occasionally and noncommercially, and
only if you received the object code with such an offer, in accord
with subsection 6b.
d) Convey the object code by offering access from a designated
place (gratis or for a charge), and offer equivalent access to the
Corresponding Source in the same way through the same place at no
further charge. You need not require recipients to copy the
Corresponding Source along with the object code. If the place to
copy the object code is a network server, the Corresponding Source
may be on a different server (operated by you or a third party)
that supports equivalent copying facilities, provided you maintain
clear directions next to the object code saying where to find the
Corresponding Source. Regardless of what server hosts the
Corresponding Source, you remain obligated to ensure that it is
available for as long as needed to satisfy these requirements.
e) Convey the object code using peer-to-peer transmission, provided
you inform other peers where the object code and Corresponding
Source of the work are being offered to the general public at no
charge under subsection 6d.
A separable portion of the object code, whose source code is excluded
from the Corresponding Source as a System Library, need not be
included in conveying the object code work.
A "User Product" is either (1) a "consumer product", which means any
tangible personal property which is normally used for personal, family,
or household purposes, or (2) anything designed or sold for incorporation
into a dwelling. In determining whether a product is a consumer product,
doubtful cases shall be resolved in favor of coverage. For a particular
product received by a particular user, "normally used" refers to a
typical or common use of that class of product, regardless of the status
of the particular user or of the way in which the particular user
actually uses, or expects or is expected to use, the product. A product
is a consumer product regardless of whether the product has substantial
commercial, industrial or non-consumer uses, unless such uses represent
the only significant mode of use of the product.
"Installation Information" for a User Product means any methods,
procedures, authorization keys, or other information required to install
and execute modified versions of a covered work in that User Product from
a modified version of its Corresponding Source. The information must
suffice to ensure that the continued functioning of the modified object
code is in no case prevented or interfered with solely because
modification has been made.
If you convey an object code work under this section in, or with, or
specifically for use in, a User Product, and the conveying occurs as
part of a transaction in which the right of possession and use of the
User Product is transferred to the recipient in perpetuity or for a
fixed term (regardless of how the transaction is characterized), the
Corresponding Source conveyed under this section must be accompanied
by the Installation Information. But this requirement does not apply
if neither you nor any third party retains the ability to install
modified object code on the User Product (for example, the work has
been installed in ROM).
The requirement to provide Installation Information does not include a
requirement to continue to provide support service, warranty, or updates
for a work that has been modified or installed by the recipient, or for
the User Product in which it has been modified or installed. Access to a
network may be denied when the modification itself materially and
adversely affects the operation of the network or violates the rules and
protocols for communication across the network.
Corresponding Source conveyed, and Installation Information provided,
in accord with this section must be in a format that is publicly
documented (and with an implementation available to the public in
source code form), and must require no special password or key for
unpacking, reading or copying.
7. Additional Terms.
"Additional permissions" are terms that supplement the terms of this
License by making exceptions from one or more of its conditions.
Additional permissions that are applicable to the entire Program shall
be treated as though they were included in this License, to the extent
that they are valid under applicable law. If additional permissions
apply only to part of the Program, that part may be used separately
under those permissions, but the entire Program remains governed by
this License without regard to the additional permissions.
When you convey a copy of a covered work, you may at your option
remove any additional permissions from that copy, or from any part of
it. (Additional permissions may be written to require their own
removal in certain cases when you modify the work.) You may place
additional permissions on material, added by you to a covered work,
for which you have or can give appropriate copyright permission.
Notwithstanding any other provision of this License, for material you
add to a covered work, you may (if authorized by the copyright holders of
that material) supplement the terms of this License with terms:
a) Disclaiming warranty or limiting liability differently from the
terms of sections 15 and 16 of this License; or
b) Requiring preservation of specified reasonable legal notices or
author attributions in that material or in the Appropriate Legal
Notices displayed by works containing it; or
c) Prohibiting misrepresentation of the origin of that material, or
requiring that modified versions of such material be marked in
reasonable ways as different from the original version; or
d) Limiting the use for publicity purposes of names of licensors or
authors of the material; or
e) Declining to grant rights under trademark law for use of some
trade names, trademarks, or service marks; or
f) Requiring indemnification of licensors and authors of that
material by anyone who conveys the material (or modified versions of
it) with contractual assumptions of liability to the recipient, for
any liability that these contractual assumptions directly impose on
those licensors and authors.
All other non-permissive additional terms are considered "further
restrictions" within the meaning of section 10. If the Program as you
received it, or any part of it, contains a notice stating that it is
governed by this License along with a term that is a further
restriction, you may remove that term. If a license document contains
a further restriction but permits relicensing or conveying under this
License, you may add to a covered work material governed by the terms
of that license document, provided that the further restriction does
not survive such relicensing or conveying.
If you add terms to a covered work in accord with this section, you
must place, in the relevant source files, a statement of the
additional terms that apply to those files, or a notice indicating
where to find the applicable terms.
Additional terms, permissive or non-permissive, may be stated in the
form of a separately written license, or stated as exceptions;
the above requirements apply either way.
8. Termination.
You may not propagate or modify a covered work except as expressly
provided under this License. Any attempt otherwise to propagate or
modify it is void, and will automatically terminate your rights under
this License (including any patent licenses granted under the third
paragraph of section 11).
However, if you cease all violation of this License, then your
license from a particular copyright holder is reinstated (a)
provisionally, unless and until the copyright holder explicitly and
finally terminates your license, and (b) permanently, if the copyright
holder fails to notify you of the violation by some reasonable means
prior to 60 days after the cessation.
Moreover, your license from a particular copyright holder is
reinstated permanently if the copyright holder notifies you of the
violation by some reasonable means, this is the first time you have
received notice of violation of this License (for any work) from that
copyright holder, and you cure the violation prior to 30 days after
your receipt of the notice.
Termination of your rights under this section does not terminate the
licenses of parties who have received copies or rights from you under
this License. If your rights have been terminated and not permanently
reinstated, you do not qualify to receive new licenses for the same
material under section 10.
9. Acceptance Not Required for Having Copies.
You are not required to accept this License in order to receive or
run a copy of the Program. Ancillary propagation of a covered work
occurring solely as a consequence of using peer-to-peer transmission
to receive a copy likewise does not require acceptance. However,
nothing other than this License grants you permission to propagate or
modify any covered work. These actions infringe copyright if you do
not accept this License. Therefore, by modifying or propagating a
covered work, you indicate your acceptance of this License to do so.
10. Automatic Licensing of Downstream Recipients.
Each time you convey a covered work, the recipient automatically
receives a license from the original licensors, to run, modify and
propagate that work, subject to this License. You are not responsible
for enforcing compliance by third parties with this License.
An "entity transaction" is a transaction transferring control of an
organization, or substantially all assets of one, or subdividing an
organization, or merging organizations. If propagation of a covered
work results from an entity transaction, each party to that
transaction who receives a copy of the work also receives whatever
licenses to the work the party's predecessor in interest had or could
give under the previous paragraph, plus a right to possession of the
Corresponding Source of the work from the predecessor in interest, if
the predecessor has it or can get it with reasonable efforts.
You may not impose any further restrictions on the exercise of the
rights granted or affirmed under this License. For example, you may
not impose a license fee, royalty, or other charge for exercise of
rights granted under this License, and you may not initiate litigation
(including a cross-claim or counterclaim in a lawsuit) alleging that
any patent claim is infringed by making, using, selling, offering for
sale, or importing the Program or any portion of it.
11. Patents.
A "contributor" is a copyright holder who authorizes use under this
License of the Program or a work on which the Program is based. The
work thus licensed is called the contributor's "contributor version".
A contributor's "essential patent claims" are all patent claims
owned or controlled by the contributor, whether already acquired or
hereafter acquired, that would be infringed by some manner, permitted
by this License, of making, using, or selling its contributor version,
but do not include claims that would be infringed only as a
consequence of further modification of the contributor version. For
purposes of this definition, "control" includes the right to grant
patent sublicenses in a manner consistent with the requirements of
this License.
Each contributor grants you a non-exclusive, worldwide, royalty-free
patent license under the contributor's essential patent claims, to
make, use, sell, offer for sale, import and otherwise run, modify and
propagate the contents of its contributor version.
In the following three paragraphs, a "patent license" is any express
agreement or commitment, however denominated, not to enforce a patent
(such as an express permission to practice a patent or covenant not to
sue for patent infringement). To "grant" such a patent license to a
party means to make such an agreement or commitment not to enforce a
patent against the party.
If you convey a covered work, knowingly relying on a patent license,
and the Corresponding Source of the work is not available for anyone
to copy, free of charge and under the terms of this License, through a
publicly available network server or other readily accessible means,
then you must either (1) cause the Corresponding Source to be so
available, or (2) arrange to deprive yourself of the benefit of the
patent license for this particular work, or (3) arrange, in a manner
consistent with the requirements of this License, to extend the patent
license to downstream recipients. "Knowingly relying" means you have
actual knowledge that, but for the patent license, your conveying the
covered work in a country, or your recipient's use of the covered work
in a country, would infringe one or more identifiable patents in that
country that you have reason to believe are valid.
If, pursuant to or in connection with a single transaction or
arrangement, you convey, or propagate by procuring conveyance of, a
covered work, and grant a patent license to some of the parties
receiving the covered work authorizing them to use, propagate, modify
or convey a specific copy of the covered work, then the patent license
you grant is automatically extended to all recipients of the covered
work and works based on it.
A patent license is "discriminatory" if it does not include within
the scope of its coverage, prohibits the exercise of, or is
conditioned on the non-exercise of one or more of the rights that are
specifically granted under this License. You may not convey a covered
work if you are a party to an arrangement with a third party that is
in the business of distributing software, under which you make payment
to the third party based on the extent of your activity of conveying
the work, and under which the third party grants, to any of the
parties who would receive the covered work from you, a discriminatory
patent license (a) in connection with copies of the covered work
conveyed by you (or copies made from those copies), or (b) primarily
for and in connection with specific products or compilations that
contain the covered work, unless you entered into that arrangement,
or that patent license was granted, prior to 28 March 2007.
Nothing in this License shall be construed as excluding or limiting
any implied license or other defenses to infringement that may
otherwise be available to you under applicable patent law.
12. No Surrender of Others' Freedom.
If conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot convey a
covered work so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you may
not convey it at all. For example, if you agree to terms that obligate you
to collect a royalty for further conveying from those to whom you convey
the Program, the only way you could satisfy both those terms and this
License would be to refrain entirely from conveying the Program.
13. Use with the GNU Affero General Public License.
Notwithstanding any other provision of this License, you have
permission to link or combine any covered work with a work licensed
under version 3 of the GNU Affero General Public License into a single
combined work, and to convey the resulting work. The terms of this
License will continue to apply to the part which is the covered work,
but the special requirements of the GNU Affero General Public License,
section 13, concerning interaction through a network will apply to the
combination as such.
14. Revised Versions of this License.
The Free Software Foundation may publish revised and/or new versions of
the GNU General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the
Program specifies that a certain numbered version of the GNU General
Public License "or any later version" applies to it, you have the
option of following the terms and conditions either of that numbered
version or of any later version published by the Free Software
Foundation. If the Program does not specify a version number of the
GNU General Public License, you may choose any version ever published
by the Free Software Foundation.
If the Program specifies that a proxy can decide which future
versions of the GNU General Public License can be used, that proxy's
public statement of acceptance of a version permanently authorizes you
to choose that version for the Program.
Later license versions may give you additional or different
permissions. However, no additional obligations are imposed on any
author or copyright holder as a result of your choosing to follow a
later version.
15. Disclaimer of Warranty.
THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
16. Limitation of Liability.
IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
SUCH DAMAGES.
17. Interpretation of Sections 15 and 16.
If the disclaimer of warranty and limitation of liability provided
above cannot be given local legal effect according to their terms,
reviewing courts shall apply local law that most closely approximates
an absolute waiver of all civil liability in connection with the
Program, unless a warranty or assumption of liability accompanies a
copy of the Program in return for a fee.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
state the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This program is free software: you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation, either version 3 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License
along with this program. If not, see <https://www.gnu.org/licenses/>.
Also add information on how to contact you by electronic and paper mail.
If the program does terminal interaction, make it output a short
notice like this when it starts in an interactive mode:
<program> Copyright (C) <year> <name of author>
This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, your program's commands
might be different; for a GUI interface, you would use an "about box".
You should also get your employer (if you work as a programmer) or school,
if any, to sign a "copyright disclaimer" for the program, if necessary.
For more information on this, and how to apply and follow the GNU GPL, see
<https://www.gnu.org/licenses/>.
The GNU General Public License does not permit incorporating your program
into proprietary programs. If your program is a subroutine library, you
may consider it more useful to permit linking proprietary applications with
the library. If this is what you want to do, use the GNU Lesser General
Public License instead of this License. But first, please read
<https://www.gnu.org/licenses/why-not-lgpl.html>.

<h2 class="title">FVM 3 Release Notes</h2>
<div class="accordion">
<h3>Important JS and JavaScript changes</h3>
<div>
<p><strong>Notes:</strong></p>
<p>JavaScript merging functionality went through a significant change on FVM 3 and it now requires manual configuration to work.</p>
<p>If you are upgrading from FVM 2 please refer to the help section below for more information on the settings.</p>
<p>If you just installed the plugin, please note that JS is not being optimized yet. You have to choose which files to be render blocking and which ones to be deferred, plus it's inline script dependencies (if any). </p>
<p>Previously, FVM merged everything and relied on having options to ignore scripts. This option frequently created issues with other plugin updates, when they changed something JavaScript related.</p>
<p>Please understand that this plugin is and it has always been aimed at being a tool for advanced users and developers, so it's not meant just be plug and play, without manual settings in place.</p>
<p>There is a new method to optimize third party scripts and load them on user interaction or automatically, after 5 seconds. This is a more recommended method to optimize scripts, as compared to FVM 2 which used document.write and other deprecated methods.</p>
<p>Please refer to the JavaScript help section further down on this page to understand how you can optimize your scripts.</p>
</div>
<h3>Relevant CSS and Fonts changes</h3>
<div>
<p><strong>Notes:</strong></p>
<p>You can now ignore or completely remove CSS files by URI Path or domain name (such as google fonts or other unwanted CSS files).</p>
<p>Known fonts, icon, animation and some other CSS files now have an option to be merged separately and loaded Async.</p>
<p>FVM now preloads the external CSS files on the header, before render blocking them later on the page.</p>
</div>
<h3>Relevant Cache changes</h3>
<div>
<p><strong>Notes:</strong></p>
<p>Purging cache on FVM, renames the file name in order to bypass CDN and browser cache, however, expired CSS and JS cache files are only deleted 24 hours (by default) after your last cache purge request.</p>
<p>This is needed because some hosting services can cache your HTML regardless of your cache purge request. If we were to delete the FVM cached files right away, it would break your layout for anonymous users, as the files would no longer exist but your page would still be referencing them.</p>
</div>
<h3>Other changes</h3>
<div>
<p><strong>Notes:</strong></p>
<p>Preconnect and Preload Headers have been removed (please use your own PHP code and conditional tags for that).</p>
<p>Critical Path CSS option has been removed (add your own code with code and <code>&lt;style id=&quot;critical-path&quot;&gt;</code> your code &lt;/style&gt; ).</p>
</div>
</div>
<div style="height: 20px;"></div>
<h2 class="title">Global Settings</h2>
<div class="accordion">
<h3>Purge Minified CSS/JS files instantly</h3>
<div>
<p><strong>Notes:</strong></p>
<p>When you purge CSS/JS files instantly, all CSS and JS cache files are deleted immediately when you clear everything on FVM. While this is great during development, it may cause issues when your hosting is doing page caching that cannot be purged by FVM. For example, if you were to delete the CSS and JS files instantly without purging the full page cache, that page cache would now be pointing to deleted files.</p>
<p>If you deselect this option, whenever you clear everything on FVM, it will only try to delete files that are older than 24h (and hopefully this should be enough for your hosting to expire the page cache automatically). That way, even if your hosting is still showing your page cache to anonymous users, the referred CSS and JS files will still be available.</p>
<p>If you are not sure about page caching on your server or hosting provider, you should keep this option disabled.</p>
</div>
</div>
<div style="height: 20px;"></div>
<h2 class="title">HTML Settings</h2>
<div class="accordion">
<h3>Enable HTML Processing</h3>
<div>
<p><strong>Notes:</strong></p>
<p>You need to enable this option, for any other options in the HTML section to work.</p>
</div>
<h3>Strip HTML Comments</h3>
<div>
<p><strong>Notes:</strong></p>
<p>Some plugins may need to use comments for certain functionality to work, however this is quite rare. The benefit of removing comments is usually very small, so if needed you can disable this setting.</p>
</div>
<h3>Cleanup Header</h3>
<div>
<p><strong>Notes:</strong></p>
<p>This options removes resource hints, generator tags, shortlinks, manifest link, etc from the header.</p>
<p>The header should be kept as lean as possible for the best TTFB response times and LCP metrics, but if you later find that you need some of the stuff that is removed by this option, you can disable this setting.</p>
</div>
<h3>Remove Emoji</h3>
<div>
<p><strong>Notes:</strong></p>
<p>This will remove the default emoji scripts from wordpress, thus reducing the amount of code during page loading. If you use WordPress emoji when posting content, you should keep this option disabled.</p>
</div>
<h3>Disable HTML Minification</h3>
<div>
<p><strong>Notes:</strong></p>
<p>Although rare, it's possible for the HTML minification to strip too much code thus breaking something. You can use this option to test if that is the case and keep this option disabled if that is the case.</p>
<p>HTML minification is no longer a recommendation by gtmetrix or pagespeed insights, so you can keep this option disabled if there is any incompatibility issue.</p>
</div>
</div>
<div style="height: 20px;"></div>
<h2 class="title">CSS Settings</h2>
<div class="accordion">
<h3>Enable CSS Processing</h3>
<div>
<p><strong>Notes:</strong></p>
<p>You need to enable this option, for any other options in the CSS section to work.</p>
</div>
<h3>Merge Fonts and Icons Separately</h3>
<div>
<p><strong>Notes:</strong></p>
<p>This will try to collect and simplify all your CSS font face rules into a separate CSS file and load it async. It may be useful for de-duplication of fonts, or to evaluate how many fonts are in use. </p>
</div>
<h3>Remove "Print" stylesheets</h3>
<div>
<p><strong>Notes:</strong></p>
<p>As a generic rule this it's safe to remove it for the vast majority of sites, unless your users often need to print pages from your site and you have customized styles for when they do so.</p>
</div>
<h3>Combine CSS Files</h3>
<div>
<p><strong>Notes:</strong></p>
<p>Merging CSS is no longer recommended if your server supports HTTP/2. The feature also usually causes conflicts when merging multiple CSS files into one, due to the lack of specificity or other errors in the code. It's still available for legacy support on old installations or outdated servers that do not support HTTP/2 delivery.</p>
</div>
<h3>Disable CSS Files Minification</h3>
<div>
<p><strong>Notes:</strong></p>
<p>Although rare, it's possible that CSS files minification may strip too much code and break some style rules that are not supported by the minification library. You can always try to disable this and check if this fixes anything, then use the ignore list to exclude the file that is causing issues.</p>
</div>
<h3>Disable CSS Styles Minification</h3>
<div>
<p><strong>Notes:</strong></p>
<p>Although rare, it's possible that CSS Styles minification may strip too much code and break some style rules that are not supported by the minification library. You can always try to disable this and check if this fixes anything.</p>
</div>
<h3>Disable CSS Link Preload</h3>
<div>
<p><strong>Notes:</strong></p>
<p>CSS Link Preloading is useful when you are merging CSS files or when you defined certain paths as Async CSS. By default, FVM will send an HTTP preload request as well as adding the html preload tag on the header, which will prioritize downloading the critical styles earlier than the other resources.</p>
<p>If you select this option, these headers will be removed and your default preload resources will load earlier than the CSS files. You need to test and see what works best for you.</p>
</div>
<h3>Ignore CSS files</h3>
<div>
<p><strong>Notes:</strong></p>
<p>If there is a conflict when merging CSS files or during individual minification of a specific CSS file, you can add the path on this section and FVM will ignore the file, thus leaving it alone.</p>
</div>
<h3>Remove CSS Files</h3>
<div>
<p><strong>Notes:</strong></p>
<p>If your plugins enqueue multiple duplicate libraries with different url paths, you can add the path on this section and FVM will remove the file from the frontend, thus reducing your total CSS size.</p>
</div>
<h3>Async CSS Files</h3>
<div>
<p><strong>Notes:</strong></p>
<p>CSS files from plugins that are not rendered above the fold, should ideally be loaded async. For example, if a plugin has CSS files but you only use the element on the footer, you could add the /plugins/plugin-name/ here to async it. But you should not async CSS files that are needed for content that is visible on the critical path.</p>
<p>Also note that by loading certain CSS files async, you are changing the order of styles. This means, some styles may or may not work as intended, because now they load on a different position.</p>

<div>
<p><strong>Notes:</strong></p>
<p>You need to enable this option, for any other options in the JS section to work.</p>
</div>
<h3>Combine JS Files</h3>
<div>
<p><strong>Notes:</strong></p>
<p>Merging JS is no longer recommended if your server supports HTTP/2. The feature also usually causes conflicts when merging multiple JS files into one, due to a different order of loading or other errors in the code. It's still available for legacy support on old installations or outdated servers that do not support HTTP/2 delivery.</p>
</div>
<h3>Disable JS Files Minification</h3>
<div>
<p><strong>Notes:</strong></p>
<p>JS files minification may strip too much code and break some code that is not supported by the minification library. You can always try to disable this and check if this fixes anything, then use the ignore list to exclude the file that is causing issues.</p>
</div>
<h3>Disable JS Inline Minification</h3>
<div>
<p><strong>Notes:</strong></p>
<p>Inline JS Styles minification may strip too much code and break some code that is not supported by the minification library. You can always try to disable this and check if this fixes anything.</p>
</div>
<h3>Disable JS Link Preload</h3>
<div>
<p><strong>Notes:</strong></p>
<p>JS Link Preloading is useful when you are merging JS files or when you defined certain paths as Defer JS. By default, FVM will send an HTTP preload request as well as adding the html preload tag on the header, which will prioritize downloading the render blocking scripts earlier than the other resources.</p>
<p>If you select this option, these headers will be removed and your default preload resources will load earlier than the JS files. You need to test and see what works best for you.</p>
</div>
<h3>Ignore Script Files</h3>
<div>
<p><strong>Notes:</strong></p>
<p>When you are merging JS files, the order of scripts change positions and dependencies may break. Other times, a specific script is not supported by the minification and breaks as well. If you encounter issues while merging or minifying JS files, you can exclude them here and those files will be left alone.</p>
</div>
<h3>Render Blocking JS files</h3>
<div>
<p><strong>Notes:</strong></p>
<p>In most WordPress themes and for a significant amount of plugins, you usually need to render block jQuery and jQuery Migrate for compatibility reasons.</p>
<p>Some plugins may not work at all if they are not render blocking, so you should look out for browser console log errors in incognito mode.</p>
<p><strong>Recommended Default Settings:</strong></p>
<p class="fvm-code-full">
/jquery-migrate<br>
/jquery.js<br>
/jquery.min.js<br>
</p>
</div>
<h3>Defer JS Files</h3>
<div>
<p><strong>Notes:</strong></p>
<p>Deferring every single script is not always the best solution, especially if those are needed to generate content above the fold. You must check your browser console log in incognito mode for possible errors after enabling this feature, and either move them to the render blocking section or check if there is any inline script that also needs to be deferred (so the order of loading is preserved).</p>
<p>Note that this is an advanced feature, hence it requires manual configuration for it to work.</p>
<p><strong>Recommended Default Settings:</strong></p>
<p class="fvm-code-full">
/ajax.aspnetcdn.com/ajax/<br>
/ajax.googleapis.com/ajax/libs/<br>
/cdnjs.cloudflare.com/ajax/libs/<br>
/stackpath.bootstrapcdn.com/bootstrap/<br>
/wp-admin/<br>
/wp-content/<br>
/wp-includes/
</p>
</div>
<h3>Defer Inline JavaScript</h3>
<div>
<p><strong>Notes:</strong></p>
<p>When you merge JS files and defer them, you are effectively changing the order in which they load, however for certain scripts, the order of loading matters. If you are deferring a certain JS file and you see an "undefined" error triggered on some inline code, you can try this option to also defer the inline code and preserve the order of execution.</p>
<p>Note however, not all scripts can work with defer so you need to test if everything is working without errors.</p>
<p>This is empty by default, unless you determine that it's needed.</p>
<p><strong>Recommended Default Settings:</strong></p>
<p class="fvm-code-full">
wp.i18n<br>
wp.apiFetch.use<br>
window.lodash<br>
wp.hooks<br>
wp.url
</p>
</div>
<h3>Delay third party scripts until user interaction</h3>
<div>
<p><strong>Notes:</strong></p>
<p>Scripts like analytics, ads, tracking codes, etc, consume important CPU and network resources needed for the initial page view. You can force certain plugins to wait for user interaction (mouseover, keydown, touchstart, touchmove and wheel) and the scripts will only run on these events.</p>
<p>Delaying these scripts will improve your speed because most third party scripts are not needed for showing any content (if they are, then they are on the critical path and you should not delay them). In addition, note that some codes make use of document.write and other methods, which do not support delaying (delaying will work as usual, but the script will not do anything or stop working).</p>
<p>If you have render blocking third party scripts, ask your provider if they can provide you with an async or defer implementation (else remove them, because render blocking scripts are not recommended for speed).</p>
<p><strong>Example Settings:</strong></p>
<p class="fvm-code-full">
function(w,d,s,l,i)<br>
function(f,b,e,v,n,t,s)<br>
function(h,o,t,j,a,r)<br>
www.googletagmanager.com/gtm.js<br>
gtag(<br>
fbq(<br>
</p>
</div>
<h3>Remove JavaScript Scripts</h3>
<div>
<p><strong>Notes:</strong></p>
<p>This can be used when you want to remove a duplicate JS file from the frontend source. However, if this is for a third party script you added to the header or footer (either code or via some plugin), it's better if you delete it at the source.</p>

<h2 class="title">CDN Settings</h2>
<div class="accordion">
<h3>Enable CDN Processing</h3>
<div>
<p><strong>Notes:</strong></p>
<p>You need to enable this option, for any other options in the CDN section to work.</p>
</div>
<h3>Enable CDN for merged CSS files</h3>
<div>
<p><strong>Notes:</strong></p>
<p>When selecting this option, FVM will replace your domain name with the CDN domain, for the generated CSS cache file.</p>
<p>Under certain situations, you may not want to serve the CSS file from the CDN, such as when your server compression level is significantly higher than the CDN (smaller file than the one delivered by the CDN).</p>
<p>Also bare in mind, that if the CSS file is served from the CDN, any static assets inside the CSS file that make use of relative paths, will also be cached and served from the CDN, which may also be undesirable in certain situations.</p>
</div>
<h3>Enable CDN for merged JS files</h3>
<div>
<p><strong>Notes:</strong></p>
<p>When selecting this option, FVM will replace your domain name with the CDN domain, for the generated JS cache file.</p>
<p>Under certain situations, you may not want to serve the JS file from the CDN, such as when your server compression level is significantly higher than the CDN (smaller file than the one delivered by the CDN).</p>

</div>
<h3>CDN URL</h3>
<div>
<p><strong>Notes:</strong></p>
<p>This is not required for providers such as Cloudflare.com as well as any reverse proxy CDN service that doesn't change your domain name (the whole site goes through their service).</p>
<p>For other types of CDN, you are usually provided with an alternative domain name from where your static files can be served and in those cases, you would introduce your new domain name here.</p>
</div>
<h3>CDN Integration</h3>
<div>
<p><strong>Notes:</strong></p>
<p>Uses syntax from <a target="_blank" href="https://simplehtmldom.sourceforge.io/manual.htm">https://simplehtmldom.sourceforge.io/manual.htm</a> for modifying the HTML.</p>
<p>The plugin will replace your site domain url with the CDN domain for the matching HTML tags.</p>

<h3>User Options</h3>
<div>
<p><strong>Notes:</strong></p>

<h2 class="title">Other FAQ's</h2>
<div class="accordion">
<h3>Is the plugin GDPR compatible?</h3>
<div>
<p><strong>Notes:</strong></p>
<p>FVM does not collect any information from you, your site or your users. It also doesn't require cookies to work, therefore it's fully GDPR compatible.</p>
</div>
<h3>How do I know if the plugin is working?</h3>
<div>
<p><strong>Notes:</strong></p>
<p>For compatibility reasons, the plugin only optimizes anonymous users by default. That means, you need to open another browser window, or use incognito mode to test and see what it's doing. Logged in users will not see the optimizations, unless you manually enable certain user roles (not recommended for complex websites, unless you know what you are doing).</p>
</div>
<h3>How do I purge the cache?</h3>
<div>
<p><strong>Notes:</strong></p>
<p>Please note that FVM is not a page cache plugin and it doesn't cache your content. The only time you should need to purge it's cache, is when you edit a css or js file.</p>
<p>If your HTML page is being cached somewhere else, you must purge your cache either, unless FVM supports it natively.</p>
</div>
<h3>Why am I getting 404 error not found for the generated CSS or JS files?</h3>
<div>
<p><strong>Notes:</strong></p>
<p>You deleted the FVM cache but forgot to purge the HTML page cache, or you are lacking writing permissions on the cache directory and files are not being created. </p>
<p>You must purge your page cache either on some other cache plugin or at your server/hosting level for your page to update and find the latest merged file paths.</p>
<p>Note that some hosts rate limit the amount of times you can purge caches to once every few minutes, so you may be purging and it doesn't work, because you are being rate limited by your hosting cache system.</p>
<p>Avoid doing development on live sites and use a staging server without cache for testing. Production servers are for deploying once and leave it until the next deployment cycle.</p>
</div>
<h3>Why is my site layout broke after an update, a configuration change, or some other change?</h3>
<div>
<p><strong>Notes:</strong></p>
<p>You must check your browser console log in incognito mode, for possible errors after enabling certain features, deferring scripts or using some other optimization plugins, which may be conflicting with FVM optimization.</p>
<p>If there are no errors, disable each option one by one on FVM (html processing, css processing, js processing, etc) until you find the feature breaking it. After that, adjust and tweak those settings accordingly, or hire a developer to help you.</p>
</div>
<h3>How can I download an older version of FVM for testing purposes?</h3>
<div>
<p><strong>Notes:</strong></p>
<p>It's not recommended you do that, but if you want to test something, you can do so from the <a target="_blank" href="https://plugins.svn.wordpress.org/fast-velocity-minify/tags/">SVN repository</a> on WordPress.</p>
</div>
<h3>How do I undo all optimizations done by FVM?</h3>
<div>
<p><strong>Notes:</strong></p>
<p>Simply disable the plugin, and make sure to purge all page caches (Cache Plugins, Hosting, OPCache, etc).</p>
<p>Note that some hosts rate limit the amount of times you can purge caches to once every few minutes, so you may be purging and it doesn't work, because you are being rate limited by your hosting cache system. If that happens, just wait and try again later or ask your hosting to manually purge all caches on the server.</p>
<p>You can also delete any database entries on the wp_options table starting with fastvelocity to completely purge it.</p>
<p>FVM does not modify your site. It runs after your template loads and filters the final HTML to present it to your users, in a more optimized way.</p>
</div>
<h3>I have disabled FVM but somehow the cache files are still being generated?</h3>
<div>
<p><strong>Notes:</strong></p>
<p>If you already purged all caches available, please ensure you have deleted the plugin and that it's no longer visible via wp-admin. If you still see references to FVM in incognito mode via google chrome, that means your server still has full page cache in memory that needs to be cleared.</p>
<p>A few hosting providers will put your files on a remote storage and cache your disk and files in memory to speed things up, which may cause code to be cached even if you have completely deleted it from the remote storage. This means, it may take a few minutes, or several hours for the actual code to update. In that case, restart the server or ask your hosting to purge all disk and page caching memory.</p>
</div>
<h3>Where can I get support or ask questions about the plugin?</h3>
<div>
<p><strong>Notes:</strong></p>
<p>You can ask for help on <a href="https://wordpress.org/support/plugin/fast-velocity-minify/">https://wordpress.org/support/plugin/fast-velocity-minify/</a> but please note we cannot guide you on which files to merge or how to solve JavaScript conflicts. You need to try different settings (trial and error) and open a separate window in incognito mode, to look for console log errors on your browser, and adjust settings as needed.</p>
</div>
<h3>How is it possible that some scan is showing malware on the plugin?</h3>
<div>
<p><strong>Notes:</strong></p>
<p>I guarantee that the plugin is 100% clean of malware, provided you have downloaded the plugin from the official WordPress source AND that your other plugins, theme or core is not compromised.</p>
<p>Malware can infect any plugin (even security plugins) regardless of the point of entry. Sometimes it propagates from different areas (including other sites you may have on the same server) or through a vulnerability on another theme or plugin (even disabled plugins or themes sometimes). </p>
<p>For that reason, if there is already malware on any JS files or CSS being merged by FVM, they would still be merged as they are, as FVM also reads them as they are. </p>
<p>If you are seeing malware on any cache file related to FVM, simply purge all caches and delete the FVM plugin. Then hire someone to manually audit the site (plugins or automated malware checks are not 100% accurate). You can then reinstall the FVM plugin from the official source on wordpress.org or via wp-admin if you like.</p>
</div>

* [1] - tag name
* ([\w:\*-]*)
* Matches the tag name consisting of zero or more words, colons,
* asterisks and hyphens.
*
* [2] - id name
* (?:\#([\w-]+))
* Optionally matches a id name, consisting of an "#" followed by
* the id name (one or more words and hyphens).
*
* [3] - class names (including dots)
* (?:\.([\w\.-]+))?
* Optionally matches a list of classs, consisting of an "."
* followed by the class name (one or more words and hyphens)
* where multiple classes can be chained (i.e. ".foo.bar.baz")
*
* [4] - attributes
* ((?:\[@?(?:!?[\w:-]+)(?:(?:[!*^$|~]?=)[\"']?(?:.*?)[\"']?)?(?:\s*?(?:[iIsS])?)?\])+)?

=== Fast Velocity Minify ===

Requires at least: 4.9
Requires PHP: 5.6

Improve your speed score on GTmetrix, Pingdom Tools and Google PageSpeed Insights by adjusting your CSS and JS files (defer, async, minify, combine, etc), compressing HTML, simplifying fonts and a few more speed optimization options.
== Description ==
HTML, CSS & JS optimization plugin for developers and advanced users. Note you need to look into the HELP tab after installing the plugin and manually configure it for your site. Each site is different, so the default recommendations may or may not work for you and you will need to test and find out how to adjust your settings.
Minification is done on the frontend during the first uncached request. Once the first request is processed, any other pages that require the same set of CSS and JS files will be able to reuse the same generated static CSS or JS file.
If your cache is growing significantly, this could mean one of your CSS or JS files is dynamic and changes on every pageview. In that case, you would need to add the file to the ignore list, else the cache would grow indefinitely (because obviously the original files themselves are dynamic and when you minify, the plugin sees a different file).
Kindly read the HELP section after installing the plugin, about possible issues and how to solve them.
= Additional Optimization =
I can offer you additional `custom made` optimization on top of this plugin. If you would like to hire me, please visit my profile links for further information.
= WP-CLI Commands =
* Purge all caches: `wp fvm purge`
* Purge all caches on a network site: `wp --url=blog.example.com fvm purge`
* Purge all caches on the entire network (linux): `wp site list --field=url | xargs -n1 -I % wp --url=% fvm purge`
= How to customize the cache path ? =
You need a public directory to store and serve minified cache files. If you need to customize the path and url, you need to edit your `wp-config.php` and add both `define('FVM_DIR', '/path/to/example.com/your/public/directory');` and `define('FVM_URL', 'https://example.com/your/public/directory');` .
== Installation ==
1. Upload the plugin folder to the `/wp-content/plugins/` directory or upload the zip within WordPress
2. Activate the plugin through the `Plugins` menu in WordPress
3. Configure the options under: `Settings > Fast Velocity Minify` and that's it.
== Screenshots ==
1. The Settings page.
