GNU GENERAL PUBLIC LICENSE
Version 3, 29 June 2007
Copyright (C) 2007 Free Software Foundation, Inc. <http://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 <http://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
<http://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
<http://www.gnu.org/philosophy/why-not-lgpl.html>.

Coding style
------------
This project is programmed using the Linux kernel coding style, see
http://lxr.linux.no/linux/Documentation/CodingStyle for details.
Please use the same style for any code contributions, thanks!
The Python decoders should follow the usual Python conventions and use
Python idioms as far as it makes sense. The coding style should mostly follow
the Python PEP-8, which includes the convention of 4 spaces for indentation.
See http://www.python.org/dev/peps/pep-0008/ for details.
Contributions
-------------
- Patches should be sent to the development mailinglist at
sigrok-devel@lists.sourceforge.net (please subscribe to the list first).
https://lists.sourceforge.net/lists/listinfo/sigrok-devel
- Alternatively, you can also clone the git repository and let us know
from where to pull/review your changes. You can use gitorious.org,
github.com, or any other public git hosting site.
Random notes
------------
- Don't do variable declarations in compound statements, only at the
beginning of a function.
- Generally avoid assigning values to variables at declaration time,
especially so for complex and/or run-time dependent values.
- Consistently use g_*malloc() / g_*malloc0(). Do not use standard
malloc()/calloc() if it can be avoided (sometimes other libs such
as libftdi can return malloc()'d memory, for example).
- Always properly match allocations with the proper *free() functions. If
glib's g_*malloc()/g_*malloc0() was used, use g_free() to free the
memory. Otherwise use standard free(). Never use the wrong function!
- We assume that "small" memory allocations (< 1MB) will always succeed.
Thus, it's fine to use g_malloc() or g_malloc0() for allocations of
simple/small structs and such (instead of using g_try_malloc()), and
there's no need to check the return value.
Do use g_try_malloc() or g_try_malloc0() for large (>= 1MB) allocations
and check the return value.
- You should never print any messages (neither to stdout nor stderr nor
elsewhere) "manually" via e.g. printf() or g_log() or similar functions.
Only srd_err()/srd_warn()/srd_info()/srd_dbg()/srd_spew() should be used.
- Use glib's gboolean / TRUE / FALSE for boolean types consistently.
Do not use <stdbool.h> and its true / false, and do not invent private
definitions for this either.
- Consistently use the same naming convention for #include guards in headers:
<PROJECTNAME>_<PATH_TO_FILE>_<FILE>
This ensures that all #include guards are always unique and consistent.
Example: LIBSIGROKDECODE_LIBSIGROKDECODE_INTERNAL_H
- Consistently use the same naming convention for API functions:
<libprefix>_<groupname>_<action>().
Examples:
srd_log_loglevel_set(), srd_log_loglevel_get(), srd_log_handler_set(),
srd_log_handler_set_default(), and so on.
Getter/setter function names should usually end with "_get" or "_set".
Functions creating new "objects" should end with "_new".
Functions destroying "objects" should end with "_destroy".
Functions adding or removing items (e.g. from lists) should end with
either "_add" or "_remove".
Functions operating on all items from a list (not on only one of them),
should end with "_all", e.g. "_remove_all", "_get_all", and so on.
Use "_remove_all" in favor of "_clear" for consistency.
- All enums should generally use an explicit start number of 10000.
If there are multiple "categories" in the enum entries, each category
should be 10000 entries apart from the next one. The start of categories
are thus 10000, 20000, 30000, and so on.
Adding items to an enum MUST always append to a "category", never add
items in the middle of a category. The order of items MUST NOT be changed.
Any of the above would break the ABI.
The enum item 0 is special and is used as terminator in some lists, thus
enums should not use this for "valid" entries (and start at 10000 instead).
Doxygen
-------
- In Doxygen comments, put an empty line between the block of @param lines
and the final @return line. The @param lines themselves (if there is more
than one) are not separated by empty lines.
- Mark private functions (SRD_PRIV) with /** @private */, so that Doxygen
doesn't include them in the output. Functions that are "static" anyway
don't need to be marked like this.
- Mark private variables/#defines with /** @cond PRIVATE */ and
/** @endcond */, so that Doxygen doesn't include them in the output.
Variables that are "static" don't need to be marked like this.
- Mark all public API functions (SRD_API) with a @since tag which indicates
in which release the respective function was added (e.g. "@since 0.1.0").
If the function has existed before, but its API changed later, the @since
tag should mention only the release when the API last changed.
Example: The srd_foo() call was added in 0.1.0, but the API changed in
the later 0.2.0 release. The docs should read "@since 0.2.0" in that case.
Non-public functions (static ones, and those marked SRD_PRIV) don't need
to have @since markers.
The @since tag should be the last one, i.e. it should come after @param,
@return, @see, and so on.
Protocol decoder guidelines
---------------------------
- The 'desc' metadata field for a protocol decoder, which contains a
short, one-line description of the protocol/bus, should be at most 55
characters long, and end with a full stop. This short description can be
displayed on the command-line using "sigrok-cli -V -l 3", or in various
different places in GUIs.
- Longer, multi-line descriptions should be placed in the protocol
decoder's __init__.py file as docstring. It can be viewed (for a specific
protocol decoder, e.g., UART) via "sigrok-cli -a uart", or in various
other places in GUIs.
- Generally use strings for states (of the PD state machine), not integers.
This avoids having to keep a list of state definitions at the top of file.
The performance overhead for this is negligible in practice.
Recommended:
self.state = 'IDLE'
self.state = 'GET STOP BIT'
Not recommended:
self.state = IDLE
self.state = GET_STOP_BIT
(where IDLE = 0 and GET_STOP_BIT = 1, for example)
- Generally use strings for commands/IDs in generated protocol packets.
This avoids having to know magic numbers of the PD in higher-level PDs.
The performance overhead for this is negligible in practice.
Recommended:
self.put(x, y, p, ['STOPBIT', 0, 0])
self.put(x, y, p, ['ADDRESS READ', 0x51])
Not recommended:
self.put(x, y, p, [STOPBIT, 0, 0])
self.put(x, y, p, [ADDRESS_READ, 0x51])
(with STOPBIT = 3 and ADDRESS_READ = 7, for example)
- Use ALL-CAPS names for PD states and protocol packet commands/ID.
Words should be separated by spaces (not underscores or the like).
Recommended:
'FIND ADDRESS', 'GET TEMPERATURE', 'START'
Not recommended:
'FIND_ADDRESS', 'Get Temperature', 'start'
Testsuite
---------
You can run the libsigrokdecode testsuite using:
$ make check
Protocol decoder test framework
-------------------------------
Please see the sigrok-test repository for a protocol decoder test suite that
checks the decoded data of various PDs against known-good reference data.
Release engineering
-------------------
See
http://sigrok.org/wiki/Developers/Release_process
for a list of items that need to be done when releasing a new tarball.

0.3.0 (2014-05-06)
------------------
Note: This release DOES change the libsigrokdecode public C API. This
means it is NOT backwards-compatible and frontends will need updates.
* New supported protocol decoders:
- guess_bitrate Guess the bitrate/baudrate of a signal
- ir_nec NEC infrared remote control protocol
- ir_rc5 RC-5 infrared remote control protocol
- midi Musical Instrument Digital Interface
- parallel Parallel synchronous bus decoder
- rgb_led_spi RGB LED string decoder (SPI)
- xfp 10 Gigabit Small Form Factor Pluggable Module
- z80 Zilog Z80 microprocessor disassembly
* Add support for annotation rows, i.e. groups of annotation classes that
are supposed to be displayed on the same GUI "row" together.
* Add support for the new OUTPUT_BINARY feature, which allows PDs to output
decoded data in various file formats (for loading and further processing
in other tools, or for direct live piping into other tools).
* Add support for the OUTPUT_META output type. This is used by PDs for
reporting various data points to the frontends, allowing them to perform
various post-processing and statistics tasks on them (e.g. simple counts,
average/mean values, min/max values, and so on).
* The OUTPUT_PROTO output type is now called OUTPUT_PYTHON.
* All protocol decoders:
- Bump the 'api_version' field of all decoders to 2. They are no longer
compatible (and cannot be used with) older libsigrokdecode versions.
- Updates to emit proper annotation classes, annotation sample numbers,
and annotation rows for GUI usage (bugs #146, #148, #150, #151, #154,
#155, #162, #147, #163, #168, #156, #309, and #344).
- Longer and shorter annotations are now supplied for GUI usage (frontends
can for example always show the longest annotation per zoom-level).
- Extensive protocol information has been moved from the PDs to the wiki.
Example: http://sigrok.org/wiki/Protocol_decoder:Uart
- Use correct I²C / I²S names in user-visible texts (not I2C/I2S).
* dcf77:
- Fix a bug in the handling of DCF77 bit 0.
- Drop handling of the 'PON' pin, this is not DCF77 related (bug #153).
- Fix the data parity check (bug #157).
* i2c:
- Fix corner case that can yield issues when using triggers on LAs.
- Drop unneeded 'addressing' option.
- Output bit-exact annotations and data for use by stacked PDs.
* i2s:
- Add OUTPUT_BINARY support for dumping the decoded data in WAV format.
* lpc:
- Various fixes to make the PD work better (or at all).
- Fix the handling of optional channels.
- Make the RESET# pin optional.
* onewire_link:
- Split 'reset' and 'presence' annotations.
* pan1321:
- Support the JSEC, JPRO, JAAC, and JSDA commands.
- Various internal fixes and improvements.
* parallel:
- Fix internal use of the obsolete 'metadata' parameter (bug #202).
* rtc8564:
- Properly handle register 0x06 (weekday) and the 'century' bit.
* sdcard_spi:
- Emit bit-exact annotations for the register fields that need them.
- Fix a Python issue with duplicate keys in a dict (bug #191).
* spi:
- Either MISO or MOSI can be optional now, but not both (bug #175).
- The CS# pin is optional now. If the pin is supplied, it is honored
(decoding only happens when the pin is asserted). Otherwise decoding will
use every CLK edge, regardless of CS# state or CS# existence (bug #152).
- Rename the 'SCK' pin to the more common 'CLK'.
- Output bit-exact annotations and data for use by stacked PDs.
- Fix a bug occurring when only MOSI (but not MISO) was supplied.
* transitioncounter:
- Drop the obsolete 'transitioncounter' dummy protocol decoder.
* uart:
- Fix corner case that can yield issues when using triggers on LAs.
- Use 'T' for stop bits and 'P' for parity bits (shortest annotations).
- Add a data format selection option.
- Annotations for RX and TX are now emitted in different annotation rows.
- Either the RX or TX signal can be optional now (but not both).
- Fix incorrectly displayed characters (bug #201).
- Add support for OUTPUT_BINARY output for RX, TX, or both.
- Output bit-exact annotations and data for use by stacked PDs.
* uart_dump:
- Drop the obsolete 'uart_dump' decoder (the feature is now included
in the 'uart' protocol decoder itself via OUTPUT_BINARY).
* usb_packet:
- The 'usb_protocol' decoder has been renamed to 'usb_packet'.
- Various bugfixes and decoding improvements.
* usb_signalling:
- Fix decoding of individual bits, sample in the middle of bits (bug #158).
* libsigrokdecode API changes overview:
- Add srd_session_new(), srd_session_destroy(), and a session context.
- Add srd_session_metadata_set().
- The name 'probe' has been renamed to 'channel' everywhere.
- The lib no longer defineѕ names with _t suffix (POSIX reserved).
- Drop the obsolete SRD_MAX_NUM_PROBES.
- Add the SRD_CONF_SAMPLERATE config key.
- Please see the Doxygen API documentation for further details.
* Protocol decoder API:
- Metadata is passed to PDs at runtime now (not at decoder start).
PDs now have a new optional metadata() method to receive it.
- Output types are now registered via Decoder.register(), not Decoder.add().
- The report() method is now obsolete. This kind of information will be
passed to the frontends via the OUTPUT_META output type, allowing the
frontends to perform various post-processing and statistics tasks.
- PDs can now define BINARY_OUTPUT types via the 'binary' tuple.
- PDs can now define annotation rows via the 'annotation_rows' tuple.
- PD options are now a tuple of dicts. Each option is a dict containing
the keys 'id', 'desc', 'def', and 'values'. Valid option types are
UTF-8 strings, integers, and floats (bugs #254, #306, #317, #165).
- Channels, optional channels, and annotations are now tuples (not lists).
- Only load PDs of API version 2, all other versions are incompatible.
* srd_inst_channel_set_all(): Report an error if not all channels required
by the respective protocol decoder have been supplied.
* Remove some internal limitations to max. 64 channels (bug #120).
* Add a unit test suite framework for libsigrokdecode ('make check').
* Add a protocol decoder test-suite framework for developers (tests/pdtest).
* Various bugfixes:
- srd_inst_option_set(): Properly return an error on exceptions.
- srd_inst_option_set(): Fix setting of instance options, caused by class
variable clobbering or releasing borrowed references (bugs #170, #174).
- srd_decoder_load(): Error out upon invalid module names (bug #176).
- srd_decoder_load(): Don't try to load an already loaded PD twice.
- srd_decoder_load_all(): Avoid issues without prior srd_init() (bug #178).
- srd_decoder_doc_get(): Fix an issue in the unit test suite (bug #179).
- srd_pd_output_callback_add(): Honor cb_data value (bug #143).
- Fix issues with PDs not getting the samplerate (bugs #97, #132, #166).
- Don't incorrectly decrease a borrowed reference (bug #177).
- Fix various memory leaks and segfault conditions.
* Build system:
- Use pkg-config (not python3-config) to check for Python libs.
This enables (better) libsigrokdecode cross-compile support.
- PDs no longer have an extra Makefile.am, and 'make install' now
happens via a Python script.
- configure: Clearly mark required and optional libs.
- Fix an issue with DESTDIR support (bug #215).
- Add the HACKING file to the tarball.
* Updated or new build-time and runtime requirements:
- Python >= 3.2 (required)
- check >= 0.9.4 (optional, only needed for the libsigrokdecode testsuite)
- libsigrok >= 0.3.0 (optional, only needed for the developer PD testsuite)
- python3-coverage (optional, only needed for the developer PD testsuite)
* New 'make install'-time requirement:
- Python >= 3.2 (required)
0.2.0 (2013-05-04)
------------------
Note: This release DOES change the libsigrokdecode public C API. This
means it is NOT backwards-compatible and frontends will need updates.
* New supported protocol decoders:
- Dallas DS1307 RTC
* Library: Decoders now expose their options via the GSList *options field
in struct srd_decoder.
* API related changes:
- Various API documentation fixes.
- srd_decoder_list() now returns 'const GSList *' instead of 'GSList *'.
- Added new srd_strerror() and srd_strerror_name() API calls.
* Added support for optional probes for PDs.
0.1.1 (2013-01-27)
------------------
Note: This release does NOT change the libsigrokdecode public C API. This
means existing libsigrokdecode frontends should not require any changes.
However, individual PDs and their output changed, which may require
some adaptations on the user's side in some cases.
* New supported protocol decoders:
- avr_isp AVR In-System Programming
- can Controller Area Network
- jtag Joint Test Action Group (IEEE 1149.1)
- jtag_stm32 Joint Test Action Group / ST STM32
- lm75 National LM75
- lpc Low-Pin-Count
- maxim_ds28ea00 Maxim DS28EA00 1-Wire digital thermometer
- onewire_link 1-Wire serial communication bus (link layer)
- onewire_network 1-Wire serial communication bus (network layer)
- sdcard_spi Secure Digital card (SPI mode)
- tlc5620 Texas Instruments TLC5620
- uart_dump UART dump
* i2cfilter: Now outputs 'i2c' packets instead of just data bytes, so
other PDs can stack on top of it. It filters by I2C slave address.
* edid: Now takes 'i2c' packets as input.
* pan1321:
- Various bugfixes to make the PD actually work.
- Now features 'Text (short)' and 'Text (verbose)' outputs.
* usb:
- The PD is split into 'usb_signalling' and 'usb_protocol' (stacked on top).
- Various bugfixes to make the PD work (better).
- The DP/DM probes were swapped, this is now fixed.
- Preliminary support for USB low-speed (in addition to full-speed).
* mlx90614: Minor bugfixes.
* dcf77:
- Major bugfix, this PD was not working correctly at all.
- Handle PON signal.
* nunchuk: Complete rewrite, works (better) now.
* spi: Update docs, send CS# change packets, change output API slightly.
If you have a PD which stacks on top of SPI, it'll need to be adapted.
The PDs that ship with libsigrokdecode are updated already.
* mx25lxx05d:
- Implement support for the READ, RDSR, and PP commands.
- Decode status register bits.
- Fix SE command handling.
- Fix inverted SRWD bit handling.
* Various smaller style and consistency changes in code and PD descriptions.
* Fix the build with Homebrew on Mac OS X.
* Performance improvements in some PDs.
* Documentation: Update website and git URLs.
* pkg-config file: Small fix to improve behaviour on Windows with cmake.
* All PD implementation files are now named 'pd.py' consistently.
* configure script:
- Also check for python3.3-config in addition to python-config and others.
- Add missing -fvisibility=hidden to default CFLAGS.
- Fix CFLAGS handling (configure.ac amends CFLAGS, doesn't overwrite now).
* The minimum required glib version is 2.24.0 now.
* We now ship a standard INSTALL file which documents the 'configure' options.
0.1.0 (2012-04-17)
------------------
* Initial release.

README
-------------------------------------------------------------------------------
The sigrok project aims at creating a portable, cross-platform,
Free/Libre/Open-Source signal analysis software suite that supports various
device types (such as logic analyzers, oscilloscopes, multimeters, and more).
libsigrokdecode is a shared library written in C which provides the basic
API for running sigrok protocol decoders. The protocol decoders themselves
are written in Python.
Status
------
libsigrokdecode is in a usable state and has had official tarball releases.
While the API can change from release to release, this will always be
properly documented and reflected in the package version number and
in the shared library / libtool / .so-file version numbers.
However, there are _NO_ guarantees at all for stable APIs in git snapshots!
Distro packagers should only use released tarballs (no git snapshots).
Requirements
------------
- git (only needed when building from git)
- gcc (>= 4.0) or clang
- make
- autoconf >= 2.63 (only needed when building from git)
- automake >= 1.11 (only needed when building from git)
- libtool (only needed when building from git)
- pkg-config >= 0.22
- libglib >= 2.24.0
- Python >= 3.2
- check >= 0.9.4 (optional, only needed to run unit tests)
- doxygen (optional, only needed for the C API docs)
- graphviz (optional, only needed for the C API docs)
Building and installing
-----------------------
In order to get the libsigrokdecode source code and build it, run:
$ git clone git://sigrok.org/libsigrokdecode
$ cd libsigrokdecode
$ ./autogen.sh
$ ./configure
$ make
For installing libsigrokdecode:
$ make install
See INSTALL or the following wiki page for more (OS-specific) instructions:
http://sigrok.org/wiki/Building
Copyright and license
---------------------
libsigrokdecode is licensed under the terms of the GNU General Public License
(GPL), version 3 or later.
The protocol decoders (PDs) included in libsigrokdecode are an integral part
of the shared library (they are not merely external "plugins", they are not
external programs that libsigrokdecode calls via fork/exec, they cannot
function standalone without libsigrokdecode at all, the PDs and the rest of
the libsigrokdecode codebase share data structures and make function calls
to each other). Thus, since the PDs are part of the library, they are also
licensed under the terms of the GPLv3+.
While some individual source code files are licensed under the GPLv2+, and
some files are licensed under the GPLv3+, this doesn't change the fact that
the library as a whole is licensed under the terms of the GPLv3+.
Please see the individual source files for the full list of copyright holders.

'''
The SPI (Serial Peripheral Interface) protocol decoder supports synchronous
SPI(-like) protocols with a clock line, a MISO and MOSI line for data
transfer in two directions, and an optional CS# pin.
Either MISO or MOSI (but not both) can be optional.
If CS# is supplied, data is only decoded when CS# is asserted (clock
transitions where CS# is not asserted are ignored). If CS# is not supplied,
data is decoded on every clock transition (depending on SPI mode).

OUTPUT_PYTHON format:
Packet:
[<ptype>, <data1>, <data2>]
<ptype>:
- 'DATA': <data1> contains the MOSI data, <data2> contains the MISO data.
The data is _usually_ 8 bits (but can also be fewer or more bits).
Both data items are Python numbers (not strings), or None if the respective
channel was not supplied.
- 'BITS': <data1>/<data2> contain a list of bit values in this MOSI/MISO data
item, and for each of those also their respective start-/endsample numbers.
- 'CS-CHANGE': <data1> is the old CS# pin value, <data2> is the new value.
Both data items are Python numbers (0/1), not strings. At the beginning of
the decoding a packet is generated with <data1> = None and <data2> being the
initial state of the CS# pin or None if the chip select pin is not supplied.
- 'TRANSFER': <data1>/<data2> contain a list of Data() namedtuples for each
byte transferred during this block of CS# asserted time. Each Data() has
fields ss, es, and val.
Examples:
['CS-CHANGE', None, 1]
['CS-CHANGE', 1, 0]

'''
UART (Universal Asynchronous Receiver Transmitter) is a simple serial
communication protocol which allows two devices to talk to each other.
This decoder should work on all "UART-like" async protocols with one
start bit (0), 5-9 databits, an (optional) parity bit, and one or more
stop bits (1), in this order.
It can be run on one signal line (RX or TX) only, or on two lines (RX + TX).
There are various standards for the physical layer specification of the
signals, including RS232, (TTL) UART, RS485, and others. However, the logic
level of the respective pins is only relevant when acquiring the data via
a logic analyzer (you have to select the correct logic analyzer and/or
the correct place where to probe). Once the data is in digital form and
matches the "UART" description above, this protocol decoder can work with
it though, no matter whether the source was on TTL UART levels, or RS232,
or others.

'''
The SPI (Serial Peripheral Interface) protocol decoder supports synchronous
SPI(-like) protocols with a clock line, a MISO and MOSI line for data
transfer in two directions, and an optional CS# pin.
Either MISO or MOSI (but not both) can be optional.
If CS# is supplied, data is only decoded when CS# is asserted (clock
transitions where CS# is not asserted are ignored). If CS# is not supplied,
data is decoded on every clock transition (depending on SPI mode).
