.Synopsis
|
|
||||||
Activate a Python virtual environment for the current Powershell session.
|
|
||||||
|
|
||||||
.Description
|
|
||||||
Pushes the python executable for a virtual environment to the front of the
|
|
||||||
$Env:PATH environment variable and sets the prompt to signify that you are
|
|
||||||
in a Python virtual environment. Makes use of the command line switches as
|
|
||||||
well as the `pyvenv.cfg` file values present in the virtual environment.
|
|
||||||
|
|
||||||
.Parameter VenvDir
|
|
||||||
Path to the directory that contains the virtual environment to activate. The
|
|
||||||
default value for this is the parent of the directory that the Activate.ps1
|
|
||||||
script is located within.
|
|
||||||
|
|
||||||
.Parameter Prompt
|
|
||||||
The prompt prefix to display when this virtual environment is activated. By
|
|
||||||
default, this prompt is the name of the virtual environment folder (VenvDir)
|
|
||||||
surrounded by parentheses and followed by a single space (ie. '(.venv) ').
|
|
||||||
|
|
||||||
.Example
|
|
||||||
Activate.ps1
|
|
||||||
Activates the Python virtual environment that contains the Activate.ps1 script.
|
|
||||||
|
|
||||||
.Example
|
|
||||||
Activate.ps1 -Verbose
|
|
||||||
Activates the Python virtual environment that contains the Activate.ps1 script,
|
|
||||||
and shows extra information about the activation as it executes.
|
|
||||||
|
|
||||||
.Example
|
|
||||||
Activate.ps1 -VenvDir C:\Users\MyUser\Common\.venv
|
|
||||||
Activates the Python virtual environment located in the specified location.
|
|
||||||
|
|
||||||
.Example
|
|
||||||
Activate.ps1 -Prompt "MyPython"
|
|
||||||
Activates the Python virtual environment that contains the Activate.ps1 script,
|
|
||||||
and prefixes the current prompt with the specified string (surrounded in
|
|
||||||
parentheses) while the virtual environment is active.

.Description
|
|
||||||
Get-PyVenvConfig parses the values from the pyvenv.cfg file located in the
|
|
||||||
given folder, and returns them in a map.
|
|
||||||
|
|
||||||
For each line in the pyvenv.cfg file, if that line can be parsed into exactly
|
|
||||||
two strings separated by `=` (with any amount of whitespace surrounding the =)
|
|
||||||
then it is considered a `key = value` line. The left hand string is the key,
|
|
||||||
the right hand is the value.
|
|
||||||
|
|
||||||
If the value starts with a `'` or a `"` then the first and last character is
|
|
||||||
stripped from the value before being captured.
|
|
||||||
|
|

GNU GENERAL PUBLIC LICENSE
|
|
||||||
Version 2, June 1991
|
|
||||||
|
|
||||||
Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
|
|
||||||
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
|
|
||||||
Everyone is permitted to copy and distribute verbatim copies
|
|
||||||
of this license document, but changing it is not allowed.
|
|
||||||
|
|
||||||
Preamble
|
|
||||||
|
|
||||||
The licenses for most software are designed to take away your
|
|
||||||
freedom to share and change it. By contrast, the GNU General Public
|
|
||||||
License is intended to guarantee your freedom to share and change free
|
|
||||||
software--to make sure the software is free for all its users. This
|
|
||||||
General Public License applies to most of the Free Software
|
|
||||||
Foundation's software and to any other program whose authors commit to
|
|
||||||
using it. (Some other Free Software Foundation software is covered by
|
|
||||||
the GNU Lesser General Public License instead.) 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
|
|
||||||
this service 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 make restrictions that forbid
|
|
||||||
anyone to deny you these rights or to ask you to surrender the rights.
|
|
||||||
These restrictions translate to certain responsibilities for you if you
|
|
||||||
distribute copies of the software, or if you modify it.
|
|
||||||
|
|
||||||
For example, if you distribute copies of such a program, whether
|
|
||||||
gratis or for a fee, you must give the recipients all the rights that
|
|
||||||
you have. 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.
|
|
||||||
|
|
||||||
We protect your rights with two steps: (1) copyright the software, and
|
|
||||||
(2) offer you this license which gives you legal permission to copy,
|
|
||||||
distribute and/or modify the software.
|
|
||||||
|
|
||||||
Also, for each author's protection and ours, we want to make certain
|
|
||||||
that everyone understands that there is no warranty for this free
|
|
||||||
software. If the software is modified by someone else and passed on, we
|
|
||||||
want its recipients to know that what they have is not the original, so
|
|
||||||
that any problems introduced by others will not reflect on the original
|
|
||||||
authors' reputations.
|
|
||||||
|
|
||||||
Finally, any free program is threatened constantly by software
|
|
||||||
patents. We wish to avoid the danger that redistributors of a free
|
|
||||||
program will individually obtain patent licenses, in effect making the
|
|
||||||
program proprietary. To prevent this, we have made it clear that any
|
|
||||||
patent must be licensed for everyone's free use or not licensed at all.
|
|
||||||
|
|
||||||
The precise terms and conditions for copying, distribution and
|
|
||||||
modification follow.
|

|
|
||||||
GNU GENERAL PUBLIC LICENSE
|
|
||||||
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
|
|
||||||
|
|
||||||
0. This License applies to any program or other work which contains
|
|
||||||
a notice placed by the copyright holder saying it may be distributed
|
|
||||||
under the terms of this General Public License. The "Program", below,
|
|
||||||
refers to any such program or work, and a "work based on the Program"
|
|
||||||
means either the Program or any derivative work under copyright law:
|
|
||||||
that is to say, a work containing the Program or a portion of it,
|
|
||||||
either verbatim or with modifications and/or translated into another
|
|
||||||
language. (Hereinafter, translation is included without limitation in
|
|
||||||
the term "modification".) Each licensee is addressed as "you".
|
|
||||||
|
|
||||||
Activities other than copying, distribution and modification are not
|
|
||||||
covered by this License; they are outside its scope. The act of
|
|
||||||
running the Program is not restricted, and the output from the Program
|
|
||||||
is covered only if its contents constitute a work based on the
|
|
||||||
Program (independent of having been made by running the Program).
|
|
||||||
Whether that is true depends on what the Program does.
|
|
||||||
|
|
||||||
1. You may copy and distribute 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 and disclaimer of warranty; keep intact all the
|
|
||||||
notices that refer to this License and to the absence of any warranty;
|
|
||||||
and give any other recipients of the Program a copy of this License
|
|
||||||
along with the Program.
|
|
||||||
|
|
||||||
You may charge a fee for the physical act of transferring a copy, and
|
|
||||||
you may at your option offer warranty protection in exchange for a fee.
|
|
||||||
|
|
||||||
2. You may modify your copy or copies of the Program or any portion
|
|
||||||
of it, thus forming a work based on the Program, and copy and
|
|
||||||
distribute such modifications or work under the terms of Section 1
|
|
||||||
above, provided that you also meet all of these conditions:
|
|
||||||
|
|
||||||
a) You must cause the modified files to carry prominent notices
|
|
||||||
stating that you changed the files and the date of any change.
|
|
||||||
|
|
||||||
b) You must cause any work that you distribute or publish, that in
|
|
||||||
whole or in part contains or is derived from the Program or any
|
|
||||||
part thereof, to be licensed as a whole at no charge to all third
|
|
||||||
parties under the terms of this License.
|
|
||||||
|
|
||||||
c) If the modified program normally reads commands interactively
|
|
||||||
when run, you must cause it, when started running for such
|
|
||||||
interactive use in the most ordinary way, to print or display an
|
|
||||||
announcement including an appropriate copyright notice and a
|
|
||||||
notice that there is no warranty (or else, saying that you provide
|
|
||||||
a warranty) and that users may redistribute the program under
|
|
||||||
these conditions, and telling the user how to view a copy of this
|
|
||||||
License. (Exception: if the Program itself is interactive but
|
|
||||||
does not normally print such an announcement, your work based on
|
|
||||||
the Program is not required to print an announcement.)
|
|
||||||
|
|
||||||
These requirements apply to the modified work as a whole. If
|
|
||||||
identifiable sections of that work are not derived from the Program,
|
|
||||||
and can be reasonably considered independent and separate works in
|
|
||||||
themselves, then this License, and its terms, do not apply to those
|
|
||||||
sections when you distribute them as separate works. But when you
|
|
||||||
distribute the same sections as part of a whole which is a work based
|
|
||||||
on the Program, the distribution of the whole must be on the terms of
|
|
||||||
this License, whose permissions for other licensees extend to the
|
|
||||||
entire whole, and thus to each and every part regardless of who wrote it.
|
|
||||||
|
|
||||||
Thus, it is not the intent of this section to claim rights or contest
|
|
||||||
your rights to work written entirely by you; rather, the intent is to
|
|
||||||
exercise the right to control the distribution of derivative or
|
|
||||||
collective works based on the Program.
|
|
||||||
|
|
||||||
In addition, mere aggregation of another work not based on the Program
|
|
||||||
with the Program (or with a work based on the Program) on a volume of
|
|
||||||
a storage or distribution medium does not bring the other work under
|
|
||||||
the scope of this License.
|
|
||||||
|
|
||||||
3. You may copy and distribute the Program (or a work based on it,
|
|
||||||
under Section 2) in object code or executable form under the terms of
|
|
||||||
Sections 1 and 2 above provided that you also do one of the following:
|
|
||||||
|
|
||||||
a) Accompany it with the complete corresponding machine-readable
|
|
||||||
source code, which must be distributed under the terms of Sections
|
|
||||||
1 and 2 above on a medium customarily used for software interchange; or,
|
|
||||||
|
|
||||||
b) Accompany it with a written offer, valid for at least three
|
|
||||||
years, to give any third party, for a charge no more than your
|
|
||||||
cost of physically performing source distribution, a complete
|
|
||||||
machine-readable copy of the corresponding source code, to be
|
|
||||||
distributed under the terms of Sections 1 and 2 above on a medium
|
|
||||||
customarily used for software interchange; or,
|
|
||||||
|
|
||||||
c) Accompany it with the information you received as to the offer
|
|
||||||
to distribute corresponding source code. (This alternative is
|
|
||||||
allowed only for noncommercial distribution and only if you
|
|
||||||
received the program in object code or executable form with such
|
|
||||||
an offer, in accord with Subsection b above.)
|
|
||||||
|
|
||||||
The source code for a work means the preferred form of the work for
|
|
||||||
making modifications to it. For an executable work, complete source
|
|
||||||
code means all the source code for all modules it contains, plus any
|
|
||||||
associated interface definition files, plus the scripts used to
|
|
||||||
control compilation and installation of the executable. However, as a
|
|
||||||
special exception, the source code distributed need not include
|
|
||||||
anything that is normally distributed (in either source or binary
|
|
||||||
form) with the major components (compiler, kernel, and so on) of the
|
|
||||||
operating system on which the executable runs, unless that component
|
|
||||||
itself accompanies the executable.
|
|
||||||
|
|
||||||
If distribution of executable or object code is made by offering
|
|
||||||
access to copy from a designated place, then offering equivalent
|
|
||||||
access to copy the source code from the same place counts as
|
|
||||||
distribution of the source code, even though third parties are not
|
|
||||||
compelled to copy the source along with the object code.
|
|
||||||
|
|
||||||
4. You may not copy, modify, sublicense, or distribute the Program
|
|
||||||
except as expressly provided under this License. Any attempt
|
|
||||||
otherwise to copy, modify, sublicense or distribute the Program is
|
|
||||||
void, and will automatically terminate your rights under this License.
|
|
||||||
However, parties who have received copies, or rights, from you under
|
|
||||||
this License will not have their licenses terminated so long as such
|
|
||||||
parties remain in full compliance.
|
|
||||||
|
|
||||||
5. You are not required to accept this License, since you have not
|
|
||||||
signed it. However, nothing else grants you permission to modify or
|
|
||||||
distribute the Program or its derivative works. These actions are
|
|
||||||
prohibited by law if you do not accept this License. Therefore, by
|
|
||||||
modifying or distributing the Program (or any work based on the
|
|
||||||
Program), you indicate your acceptance of this License to do so, and
|
|
||||||
all its terms and conditions for copying, distributing or modifying
|
|
||||||
the Program or works based on it.
|
|
||||||
|
|
||||||
6. Each time you redistribute the Program (or any work based on the
|
|
||||||
Program), the recipient automatically receives a license from the
|
|
||||||
original licensor to copy, distribute or modify the Program subject to
|
|
||||||
these terms and conditions. You may not impose any further
|
|
||||||
restrictions on the recipients' exercise of the rights granted herein.
|
|
||||||
You are not responsible for enforcing compliance by third parties to
|
|
||||||
this License.
|
|
||||||
|
|
||||||
7. If, as a consequence of a court judgment or allegation of patent
|
|
||||||
infringement or for any other reason (not limited to patent issues),
|
|
||||||
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
|
|
||||||
distribute so as to satisfy simultaneously your obligations under this
|
|
||||||
License and any other pertinent obligations, then as a consequence you
|
|
||||||
may not distribute the Program at all. For example, if a patent
|
|
||||||
license would not permit royalty-free redistribution of the Program by
|
|
||||||
all those who receive copies directly or indirectly through you, then
|
|
||||||
the only way you could satisfy both it and this License would be to
|
|
||||||
refrain entirely from distribution of the Program.
|
|
||||||
|
|
||||||
If any portion of this section is held invalid or unenforceable under
|
|
||||||
any particular circumstance, the balance of the section is intended to
|
|
||||||
apply and the section as a whole is intended to apply in other
|
|
||||||
circumstances.
|
|
||||||
|
|
||||||
It is not the purpose of this section to induce you to infringe any
|
|
||||||
patents or other property right claims or to contest validity of any
|
|
||||||
such claims; this section has the sole purpose of protecting the
|
|
||||||
integrity of the free software distribution system, which is
|
|
||||||
implemented by public license practices. Many people have made
|
|
||||||
generous contributions to the wide range of software distributed
|
|
||||||
through that system in reliance on consistent application of that
|
|
||||||
system; it is up to the author/donor to decide if he or she is willing
|
|
||||||
to distribute software through any other system and a licensee cannot
|
|
||||||
impose that choice.
|
|
||||||
|
|
||||||
This section is intended to make thoroughly clear what is believed to
|
|
||||||
be a consequence of the rest of this License.
|
|
||||||
|
|
||||||
8. If the distribution and/or use of the Program is restricted in
|
|
||||||
certain countries either by patents or by copyrighted interfaces, the
|
|
||||||
original copyright holder who places the Program under this License
|
|
||||||
may add an explicit geographical distribution limitation excluding
|
|
||||||
those countries, so that distribution is permitted only in or among
|
|
||||||
countries not thus excluded. In such case, this License incorporates
|
|
||||||
the limitation as if written in the body of this License.
|
|
||||||
|
|
||||||
9. The Free Software Foundation may publish revised and/or new versions
|
|
||||||
of the 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 a version number of this License which applies to it and "any
|
|
||||||
later version", you have the option of following the terms and conditions
|
|
||||||
either of that version or of any later version published by the Free
|
|
||||||
Software Foundation. If the Program does not specify a version number of
|
|
||||||
this License, you may choose any version ever published by the Free Software
|
|
||||||
Foundation.
|
|
||||||
|
|
||||||
10. If you wish to incorporate parts of the Program into other free
|
|
||||||
programs whose distribution conditions are different, write to the author
|
|
||||||
to ask for permission. For software which is copyrighted by the Free
|
|
||||||
Software Foundation, write to the Free Software Foundation; we sometimes
|
|
||||||
make exceptions for this. Our decision will be guided by the two goals
|
|
||||||
of preserving the free status of all derivatives of our free software and
|
|
||||||
of promoting the sharing and reuse of software generally.
|
|
||||||
|
|
||||||
NO WARRANTY
|
|
||||||
|
|
||||||
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, 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.
|
|
||||||
|
|
||||||
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
|
|
||||||
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
|
|
||||||
REDISTRIBUTE 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.
|
|
||||||
|
|
||||||
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
|
|
||||||
convey 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 2 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, write to the Free Software Foundation, Inc.,
|
|
||||||
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
|
|
||||||
|
|
||||||
Also add information on how to contact you by electronic and paper mail.
|
|
||||||
|
|
||||||
If the program is interactive, make it output a short notice like this
|
|
||||||
when it starts in an interactive mode:
|
|
||||||
|
|
||||||
Gnomovision version 69, Copyright (C) year name of author
|
|
||||||
Gnomovision 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, the commands you use may
|
|
||||||
be called something other than `show w' and `show c'; they could even be
|
|
||||||
mouse-clicks or menu items--whatever suits your program.
|
|
||||||
|
|
||||||
You should also get your employer (if you work as a programmer) or your
|
|
||||||
school, if any, to sign a "copyright disclaimer" for the program, if
|
|
||||||
necessary. Here is a sample; alter the names:
|
|
||||||
|
|
||||||
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
|
|
||||||
`Gnomovision' (which makes passes at compilers) written by James Hacker.

This 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

GNU LESSER GENERAL PUBLIC LICENSE

|

Version 2.1, February 1999
|

|
|
||||||
Copyright (C) 1991, 1999 Free Software Foundation, Inc.
|
|
||||||
51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA
|
|

Everyone is permitted to copy and distribute verbatim copies
|
|
||||||
of this license document, but changing it is not allowed.

|

[This is the first released version of the Lesser GPL. It also counts
|
|
||||||
as the successor of the GNU Library Public License, version 2, hence
|
|
||||||
the version number 2.1.]
|
|
||||||
|
|
||||||
Preamble
|
|
||||||
|
|
||||||
The licenses for most software are designed to take away your
|
|
||||||
freedom to share and change it. By contrast, the GNU General Public
|
|
||||||
Licenses are intended to guarantee your freedom to share and change
|
|
||||||
free software--to make sure the software is free for all its users.
|
|
||||||
|
|
||||||
This license, the Lesser General Public License, applies to some
|
|
||||||
specially designated software packages--typically libraries--of the
|
|
||||||
Free Software Foundation and other authors who decide to use it. You
|
|
||||||
can use it too, but we suggest you first think carefully about whether
|
|
||||||
this license or the ordinary General Public License is the better
|
|
||||||
strategy to use in any particular case, based on the explanations
|
|
||||||
below.
|
|
||||||
|
|
||||||
When we speak of free software, we are referring to freedom of use,
|
|
||||||
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 this service if you wish); that you receive source code or can get
|
|
||||||
it if you want it; that you can change the software and use pieces of
|
|
||||||
it in new free programs; and that you are informed that you can do
|
|
||||||
these things.
|
|
||||||
|
|
||||||
To protect your rights, we need to make restrictions that forbid
|
|
||||||
distributors to deny you these rights or to ask you to surrender these
|
|
||||||
rights. These restrictions translate to certain responsibilities for
|
|
||||||
you if you distribute copies of the library or if you modify it.
|
|
||||||
|
|
||||||
For example, if you distribute copies of the library, whether gratis
|
|
||||||
or for a fee, you must give the recipients all the rights that we gave
|
|
||||||
you. You must make sure that they, too, receive or can get the source
|
|
||||||
code. If you link other code with the library, you must provide
|
|
||||||
complete object files to the recipients, so that they can relink them
|
|
||||||
with the library after making changes to the library and recompiling
|
|
||||||
it. And you must show them these terms so they know their rights.
|
|
||||||
|
|
||||||
We protect your rights with a two-step method: (1) we copyright the
|
|
||||||
library, and (2) we offer you this license, which gives you legal
|
|
||||||
permission to copy, distribute and/or modify the library.
|
|
||||||
|
|
||||||
To protect each distributor, we want to make it very clear that
|
|
||||||
there is no warranty for the free library. Also, if the library is
|
|
||||||
modified by someone else and passed on, the recipients should know
|
|
||||||
that what they have is not the original version, so that the original
|
|
||||||
author's reputation will not be affected by problems that might be
|
|
||||||
introduced by others.
|
|
||||||
|
|
||||||
Finally, software patents pose a constant threat to the existence of
|
|
||||||
any free program. We wish to make sure that a company cannot
|
|
||||||
effectively restrict the users of a free program by obtaining a
|
|
||||||
restrictive license from a patent holder. Therefore, we insist that
|
|
||||||
any patent license obtained for a version of the library must be
|
|
||||||
consistent with the full freedom of use specified in this license.
|
|
||||||
|
|
||||||
Most GNU software, including some libraries, is covered by the
|
|
||||||
ordinary GNU General Public License. This license, the GNU Lesser
|
|
||||||
General Public License, applies to certain designated libraries, and
|
|
||||||
is quite different from the ordinary General Public License. We use
|
|
||||||
this license for certain libraries in order to permit linking those
|
|
||||||
libraries into non-free programs.
|
|
||||||
|
|
||||||
When a program is linked with a library, whether statically or using
|
|
||||||
a shared library, the combination of the two is legally speaking a
|
|
||||||
combined work, a derivative of the original library. The ordinary
|
|
||||||
General Public License therefore permits such linking only if the
|
|
||||||
entire combination fits its criteria of freedom. The Lesser General
|
|
||||||
Public License permits more lax criteria for linking other code with
|
|
||||||
the library.
|
|
||||||
|
|
||||||
We call this license the "Lesser" General Public License because it
|
|
||||||
does Less to protect the user's freedom than the ordinary General
|
|
||||||
Public License. It also provides other free software developers Less
|
|
||||||
of an advantage over competing non-free programs. These disadvantages
|
|
||||||
are the reason we use the ordinary General Public License for many
|
|
||||||
libraries. However, the Lesser license provides advantages in certain
|
|
||||||
special circumstances.
|
|
||||||
|
|
||||||
For example, on rare occasions, there may be a special need to
|
|
||||||
encourage the widest possible use of a certain library, so that it
|
|
||||||
becomes a de-facto standard. To achieve this, non-free programs must
|
|
||||||
be allowed to use the library. A more frequent case is that a free
|
|
||||||
library does the same job as widely used non-free libraries. In this
|
|
||||||
case, there is little to gain by limiting the free library to free
|
|
||||||
software only, so we use the Lesser General Public License.
|
|
||||||
|
|
||||||
In other cases, permission to use a particular library in non-free
|
|
||||||
programs enables a greater number of people to use a large body of
|
|
||||||
free software. For example, permission to use the GNU C Library in
|
|
||||||
non-free programs enables many more people to use the whole GNU
|
|
||||||
operating system, as well as its variant, the GNU/Linux operating
|
|
||||||
system.
|
|
||||||
|
|
||||||
Although the Lesser General Public License is Less protective of the
|
|
||||||
users' freedom, it does ensure that the user of a program that is
|
|
||||||
linked with the Library has the freedom and the wherewithal to run
|
|
||||||
that program using a modified version of the Library.
|
|
||||||
|
|
||||||
The precise terms and conditions for copying, distribution and
|
|
||||||
modification follow. Pay close attention to the difference between a
|
|
||||||
"work based on the library" and a "work that uses the library". The
|
|
||||||
former contains code derived from the library, whereas the latter must
|
|
||||||
be combined with the library in order to run.
|
|
||||||
|
|
||||||
GNU LESSER GENERAL PUBLIC LICENSE
|
|
||||||
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
|
|
||||||
|
|
||||||
0. This License Agreement applies to any software library or other
|
|
||||||
program which contains a notice placed by the copyright holder or
|
|
||||||
other authorized party saying it may be distributed under the terms of
|
|
||||||
this Lesser General Public License (also called "this License").
|
|
||||||
Each licensee is addressed as "you".
|
|
||||||
|
|
||||||
A "library" means a collection of software functions and/or data
|
|
||||||
prepared so as to be conveniently linked with application programs
|
|
||||||
(which use some of those functions and data) to form executables.
|
|
||||||
|
|
||||||
The "Library", below, refers to any such software library or work
|
|
||||||
which has been distributed under these terms. A "work based on the
|
|
||||||
Library" means either the Library or any derivative work under
|
|
||||||
copyright law: that is to say, a work containing the Library or a
|
|
||||||
portion of it, either verbatim or with modifications and/or translated
|
|
||||||
straightforwardly into another language. (Hereinafter, translation is
|
|
||||||
included without limitation in the term "modification".)
|
|
||||||
|
|
||||||
"Source code" for a work means the preferred form of the work for
|
|
||||||
making modifications to it. For a library, complete source code means
|
|
||||||
all the source code for all modules it contains, plus any associated
|
|
||||||
interface definition files, plus the scripts used to control
|
|
||||||
compilation and installation of the library.
|
|
||||||
|
|
||||||
Activities other than copying, distribution and modification are not
|
|
||||||
covered by this License; they are outside its scope. The act of
|
|
||||||
running a program using the Library is not restricted, and output from
|
|
||||||
such a program is covered only if its contents constitute a work based
|
|
||||||
on the Library (independent of the use of the Library in a tool for
|
|
||||||
writing it). Whether that is true depends on what the Library does
|
|
||||||
and what the program that uses the Library does.
|
|
||||||
|
|
||||||
1. You may copy and distribute verbatim copies of the Library's
|
|
||||||
complete source code as you receive it, in any medium, provided that
|
|
||||||
you conspicuously and appropriately publish on each copy an
|
|
||||||
appropriate copyright notice and disclaimer of warranty; keep intact
|
|
||||||
all the notices that refer to this License and to the absence of any
|
|
||||||
warranty; and distribute a copy of this License along with the
|
|
||||||
Library.
|
|
||||||
|
|
||||||
You may charge a fee for the physical act of transferring a copy,
|
|
||||||
and you may at your option offer warranty protection in exchange for a
|
|
||||||
fee.
|
|
||||||
|
|
||||||
2. You may modify your copy or copies of the Library or any portion
|
|
||||||
of it, thus forming a work based on the Library, and copy and
|
|
||||||
distribute such modifications or work under the terms of Section 1
|
|
||||||
above, provided that you also meet all of these conditions:
|
|
||||||
|
|
||||||
a) The modified work must itself be a software library.
|
|
||||||
|
|
||||||
b) You must cause the files modified to carry prominent notices
|
|
||||||
stating that you changed the files and the date of any change.
|
|
||||||
|
|
||||||
c) You must cause the whole of the work to be licensed at no
|
|
||||||
charge to all third parties under the terms of this License.
|
|
||||||
|
|
||||||
d) If a facility in the modified Library refers to a function or a
|
|
||||||
table of data to be supplied by an application program that uses
|
|
||||||
the facility, other than as an argument passed when the facility
|
|
||||||
is invoked, then you must make a good faith effort to ensure that,
|
|
||||||
in the event an application does not supply such function or
|
|
||||||
table, the facility still operates, and performs whatever part of
|
|
||||||
its purpose remains meaningful.
|
|
||||||
|
|
||||||
(For example, a function in a library to compute square roots has
|
|
||||||
a purpose that is entirely well-defined independent of the
|
|
||||||
application. Therefore, Subsection 2d requires that any
|
|
||||||
application-supplied function or table used by this function must
|
|
||||||
be optional: if the application does not supply it, the square
|
|
||||||
root function must still compute square roots.)
|
|
||||||
|
|
||||||
These requirements apply to the modified work as a whole. If
|
|
||||||
identifiable sections of that work are not derived from the Library,
|
|
||||||
and can be reasonably considered independent and separate works in
|
|
||||||
themselves, then this License, and its terms, do not apply to those
|
|
||||||
sections when you distribute them as separate works. But when you
|
|
||||||
distribute the same sections as part of a whole which is a work based
|
|
||||||
on the Library, the distribution of the whole must be on the terms of
|
|
||||||
this License, whose permissions for other licensees extend to the
|
|
||||||
entire whole, and thus to each and every part regardless of who wrote
|
|
||||||
it.
|
|
||||||
|
|
||||||
Thus, it is not the intent of this section to claim rights or contest
|
|
||||||
your rights to work written entirely by you; rather, the intent is to
|
|
||||||
exercise the right to control the distribution of derivative or
|
|
||||||
collective works based on the Library.
|
|
||||||
|
|
||||||
In addition, mere aggregation of another work not based on the Library
|
|
||||||
with the Library (or with a work based on the Library) on a volume of
|
|
||||||
a storage or distribution medium does not bring the other work under
|
|
||||||
the scope of this License.
|
|
||||||
|
|
||||||
3. You may opt to apply the terms of the ordinary GNU General Public
|
|
||||||
License instead of this License to a given copy of the Library. To do
|
|
||||||
this, you must alter all the notices that refer to this License, so
|
|
||||||
that they refer to the ordinary GNU General Public License, version 2,
|
|
||||||
instead of to this License. (If a newer version than version 2 of the
|
|
||||||
ordinary GNU General Public License has appeared, then you can specify
|
|
||||||
that version instead if you wish.) Do not make any other change in
|
|
||||||
these notices.
|
|
||||||
|
|
||||||
Once this change is made in a given copy, it is irreversible for
|
|
||||||
that copy, so the ordinary GNU General Public License applies to all
|
|
||||||
subsequent copies and derivative works made from that copy.
|
|
||||||
|
|
||||||
This option is useful when you wish to copy part of the code of
|
|
||||||
the Library into a program that is not a library.
|
|
||||||
|
|
||||||
4. You may copy and distribute the Library (or a portion or
|
|
||||||
derivative of it, under Section 2) in object code or executable form
|
|
||||||
under the terms of Sections 1 and 2 above provided that you accompany
|
|
||||||
it with the complete corresponding machine-readable source code, which
|
|
||||||
must be distributed under the terms of Sections 1 and 2 above on a
|
|
||||||
medium customarily used for software interchange.
|
|
||||||
|
|
||||||
If distribution of object code is made by offering access to copy
|
|
||||||
from a designated place, then offering equivalent access to copy the
|
|
||||||
source code from the same place satisfies the requirement to
|
|
||||||
distribute the source code, even though third parties are not
|
|
||||||
compelled to copy the source along with the object code.
|
|
||||||
|
|
||||||
5. A program that contains no derivative of any portion of the
|
|
||||||
Library, but is designed to work with the Library by being compiled or
|
|
||||||
linked with it, is called a "work that uses the Library". Such a
|
|
||||||
work, in isolation, is not a derivative work of the Library, and
|
|
||||||
therefore falls outside the scope of this License.
|
|
||||||
|
|
||||||
However, linking a "work that uses the Library" with the Library
|
|
||||||
creates an executable that is a derivative of the Library (because it
|
|
||||||
contains portions of the Library), rather than a "work that uses the
|
|
||||||
library". The executable is therefore covered by this License.
|
|
||||||
Section 6 states terms for distribution of such executables.
|
|
||||||
|
|
||||||
When a "work that uses the Library" uses material from a header file
|
|
||||||
that is part of the Library, the object code for the work may be a
|
|
||||||
derivative work of the Library even though the source code is not.
|
|
||||||
Whether this is true is especially significant if the work can be
|
|
||||||
linked without the Library, or if the work is itself a library. The
|
|
||||||
threshold for this to be true is not precisely defined by law.
|
|
||||||
|
|
||||||
If such an object file uses only numerical parameters, data
|
|
||||||
structure layouts and accessors, and small macros and small inline
|
|
||||||
functions (ten lines or less in length), then the use of the object
|
|
||||||
file is unrestricted, regardless of whether it is legally a derivative
|
|
||||||
work. (Executables containing this object code plus portions of the
|
|
||||||
Library will still fall under Section 6.)
|
|
||||||
|
|
||||||
Otherwise, if the work is a derivative of the Library, you may
|
|
||||||
distribute the object code for the work under the terms of Section 6.
|
|
||||||
Any executables containing that work also fall under Section 6,
|
|
||||||
whether or not they are linked directly with the Library itself.
|
|
||||||
|
|
||||||
6. As an exception to the Sections above, you may also combine or
|
|
||||||
link a "work that uses the Library" with the Library to produce a
|
|
||||||
work containing portions of the Library, and distribute that work
|
|
||||||
under terms of your choice, provided that the terms permit
|
|
||||||
modification of the work for the customer's own use and reverse
|
|
||||||
engineering for debugging such modifications.
|
|
||||||
|
|
||||||
You must give prominent notice with each copy of the work that the
|
|
||||||
Library is used in it and that the Library and its use are covered by
|
|
||||||
this License. You must supply a copy of this License. If the work
|
|
||||||
during execution displays copyright notices, you must include the
|
|
||||||
copyright notice for the Library among them, as well as a reference
|
|
||||||
directing the user to the copy of this License. Also, you must do one
|
|
||||||
of these things:
|
|
||||||
|
|
||||||
a) Accompany the work with the complete corresponding
|
|
||||||
machine-readable source code for the Library including whatever
|
|
||||||
changes were used in the work (which must be distributed under
|
|
||||||
Sections 1 and 2 above); and, if the work is an executable linked
|
|
||||||
with the Library, with the complete machine-readable "work that
|
|
||||||
uses the Library", as object code and/or source code, so that the
|
|
||||||
user can modify the Library and then relink to produce a modified
|
|
||||||
executable containing the modified Library. (It is understood
|
|
||||||
that the user who changes the contents of definitions files in the
|
|
||||||
Library will not necessarily be able to recompile the application
|
|
||||||
to use the modified definitions.)
|
|
||||||
|
|
||||||
b) Use a suitable shared library mechanism for linking with the
|
|
||||||
Library. A suitable mechanism is one that (1) uses at run time a
|
|
||||||
copy of the library already present on the user's computer system,
|
|
||||||
rather than copying library functions into the executable, and (2)
|
|
||||||
will operate properly with a modified version of the library, if
|
|
||||||
the user installs one, as long as the modified version is
|
|
||||||
interface-compatible with the version that the work was made with.
|
|
||||||
|
|
||||||
c) Accompany the work with a written offer, valid for at least
|
|
||||||
three years, to give the same user the materials specified in
|
|
||||||
Subsection 6a, above, for a charge no more than the cost of
|
|
||||||
performing this distribution.
|
|
||||||
|
|
||||||
d) If distribution of the work is made by offering access to copy
|
|
||||||
from a designated place, offer equivalent access to copy the above
|
|
||||||
specified materials from the same place.
|
|
||||||
|
|
||||||
e) Verify that the user has already received a copy of these
|
|
||||||
materials or that you have already sent this user a copy.
|
|
||||||
|
|
||||||
For an executable, the required form of the "work that uses the
|
|
||||||
Library" must include any data and utility programs needed for
|
|
||||||
reproducing the executable from it. However, as a special exception,
|
|
||||||
the materials to be distributed need not include anything that is
|
|
||||||
normally distributed (in either source or binary form) with the major
|
|
||||||
components (compiler, kernel, and so on) of the operating system on
|
|
||||||
which the executable runs, unless that component itself accompanies
|
|
||||||
the executable.
|
|
||||||
|
|
||||||
It may happen that this requirement contradicts the license
|
|
||||||
restrictions of other proprietary libraries that do not normally
|
|
||||||
accompany the operating system. Such a contradiction means you cannot
|
|
||||||
use both them and the Library together in an executable that you
|
|
||||||
distribute.
|
|
||||||
|
|
||||||
7. You may place library facilities that are a work based on the
|
|
||||||
Library side-by-side in a single library together with other library
|
|
||||||
facilities not covered by this License, and distribute such a combined
|
|
||||||
library, provided that the separate distribution of the work based on
|
|
||||||
the Library and of the other library facilities is otherwise
|
|
||||||
permitted, and provided that you do these two things:
|
|
||||||
|
|
||||||
a) Accompany the combined library with a copy of the same work
|
|
||||||
based on the Library, uncombined with any other library
|
|
||||||
facilities. This must be distributed under the terms of the
|
|
||||||
Sections above.
|
|
||||||
|
|
||||||
b) Give prominent notice with the combined library of the fact
|
|
||||||
that part of it is a work based on the Library, and explaining
|
|
||||||
where to find the accompanying uncombined form of the same work.
|
|
||||||
|
|
||||||
8. You may not copy, modify, sublicense, link with, or distribute
|
|
||||||
the Library except as expressly provided under this License. Any
|
|
||||||
attempt otherwise to copy, modify, sublicense, link with, or
|
|
||||||
distribute the Library is void, and will automatically terminate your
|
|
||||||
rights under this License. However, parties who have received copies,
|
|
||||||
or rights, from you under this License will not have their licenses
|
|
||||||
terminated so long as such parties remain in full compliance.
|
|
||||||
|
|
||||||
9. You are not required to accept this License, since you have not
|
|
||||||
signed it. However, nothing else grants you permission to modify or
|
|
||||||
distribute the Library or its derivative works. These actions are
|
|
||||||
prohibited by law if you do not accept this License. Therefore, by
|
|
||||||
modifying or distributing the Library (or any work based on the
|
|
||||||
Library), you indicate your acceptance of this License to do so, and
|
|
||||||
all its terms and conditions for copying, distributing or modifying
|
|
||||||
the Library or works based on it.
|
|
||||||
|
|
||||||
10. Each time you redistribute the Library (or any work based on the
|
|
||||||
Library), the recipient automatically receives a license from the
|
|
||||||
original licensor to copy, distribute, link with or modify the Library
|
|
||||||
subject to these terms and conditions. You may not impose any further
|
|
||||||
restrictions on the recipients' exercise of the rights granted herein.
|
|
||||||
You are not responsible for enforcing compliance by third parties with
|
|
||||||
this License.
|
|
||||||
|
|
||||||
11. If, as a consequence of a court judgment or allegation of patent
|
|
||||||
infringement or for any other reason (not limited to patent issues),
|
|
||||||
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
|
|
||||||
distribute so as to satisfy simultaneously your obligations under this
|
|
||||||
License and any other pertinent obligations, then as a consequence you
|
|
||||||
may not distribute the Library at all. For example, if a patent
|
|
||||||
license would not permit royalty-free redistribution of the Library by
|
|
||||||
all those who receive copies directly or indirectly through you, then
|
|
||||||
the only way you could satisfy both it and this License would be to
|
|
||||||
refrain entirely from distribution of the Library.
|
|
||||||
|
|
||||||
If any portion of this section is held invalid or unenforceable under
|
|
||||||
any particular circumstance, the balance of the section is intended to
|
|
||||||
apply, and the section as a whole is intended to apply in other
|
|
||||||
circumstances.
|
|
||||||
|
|
||||||
It is not the purpose of this section to induce you to infringe any
|
|
||||||
patents or other property right claims or to contest validity of any
|
|
||||||
such claims; this section has the sole purpose of protecting the
|
|
||||||
integrity of the free software distribution system which is
|
|
||||||
implemented by public license practices. Many people have made
|
|
||||||
generous contributions to the wide range of software distributed
|
|
||||||
through that system in reliance on consistent application of that
|
|
||||||
system; it is up to the author/donor to decide if he or she is willing
|
|
||||||
to distribute software through any other system and a licensee cannot
|
|
||||||
impose that choice.
|
|
||||||
|
|
||||||
This section is intended to make thoroughly clear what is believed to
|
|
||||||
be a consequence of the rest of this License.
|
|
||||||
|
|
||||||
12. If the distribution and/or use of the Library is restricted in
|
|
||||||
certain countries either by patents or by copyrighted interfaces, the
|
|
||||||
original copyright holder who places the Library under this License
|
|
||||||
may add an explicit geographical distribution limitation excluding those
|
|
||||||
countries, so that distribution is permitted only in or among
|
|
||||||
countries not thus excluded. In such case, this License incorporates
|
|
||||||
the limitation as if written in the body of this License.
|
|
||||||
|
|
||||||
13. The Free Software Foundation may publish revised and/or new
|
|
||||||
versions of the Lesser 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 Library
|
|
||||||
specifies a version number of this License which applies to it and
|
|
||||||
"any later version", you have the option of following the terms and
|
|
||||||
conditions either of that version or of any later version published by
|
|
||||||
the Free Software Foundation. If the Library does not specify a
|
|
||||||
license version number, you may choose any version ever published by
|
|
||||||
the Free Software Foundation.
|
|
||||||
|
|
||||||
14. If you wish to incorporate parts of the Library into other free
|
|
||||||
programs whose distribution conditions are incompatible with these,
|
|
||||||
write to the author to ask for permission. For software which is
|
|
||||||
copyrighted by the Free Software Foundation, write to the Free
|
|
||||||
Software Foundation; we sometimes make exceptions for this. Our
|
|
||||||
decision will be guided by the two goals of preserving the free status
|
|
||||||
of all derivatives of our free software and of promoting the sharing
|
|
||||||
and reuse of software generally.
|
|
||||||
|
|
||||||
NO WARRANTY
|
|
||||||
|
|
||||||
15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
|
|
||||||
WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
|
|
||||||
EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
|
|
||||||
OTHER PARTIES PROVIDE THE LIBRARY "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
|
|
||||||
LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
|
|
||||||
THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
|
|
||||||
|
|
||||||
16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
|
|
||||||
WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
|
|
||||||
AND/OR REDISTRIBUTE THE LIBRARY 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
|
|
||||||
LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING

How to Apply These Terms to Your New Libraries
|
|
||||||
|
|
||||||
If you develop a new library, and you want it to be of the greatest
|
|
||||||
possible use to the public, we recommend making it free software that
|
|
||||||
everyone can redistribute and change. You can do so by permitting
|
|
||||||
redistribution under these terms (or, alternatively, under the terms
|
|
||||||
of the ordinary General Public License).
|
|
||||||
|
|
||||||
To apply these terms, attach the following notices to the library.
|
|
||||||
It is safest to attach them to the start of each source file to most
|
|
||||||
effectively convey 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 library's name and a brief idea of what it does.>
|
|
||||||
Copyright (C) <year> <name of author>

||||||

|
||||||
This library is free software; you can redistribute it and/or
|
|
||||||
modify it under the terms of the GNU Lesser General Public
|
|
||||||

|
|
||||||
version 2.1 of the License, or (at your option) any later version.
|
|
||||||
|
|
||||||
This library 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
|

Lesser General Public License for more details.
|
|
||||||
|
|
||||||
You should have received a copy of the GNU Lesser General Public
|

||||||
License along with this library; if not, write to the Free Software

Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA
|
|
||||||
|
|
||||||
Also add information on how to contact you by electronic and paper mail.
|
|
||||||
|
|
||||||
You should also get your employer (if you work as a programmer) or
|
|
||||||
your school, if any, to sign a "copyright disclaimer" for the library,
|
|
||||||
if necessary. Here is a sample; alter the names:
|
|
||||||
|
|
||||||
Yoyodyne, Inc., hereby disclaims all copyright interest in the
|
|
||||||
library `Frob' (a library for tweaking knobs) written by James
|

What's this?
|
|
||||||
------------
|
|
||||||
|
|
||||||
The aim of this module is to provide a common base representation of
|
|
||||||
python source code. It is currently the library powering pylint's capabilities.
|
|
||||||
|
|
||||||
It provides a compatible representation which comes from the `_ast`
|
|
||||||
module. It rebuilds the tree generated by the builtin _ast module by
|
|
||||||
recursively walking down the AST and building an extended ast. The new
|
|
||||||
node classes have additional methods and attributes for different
|
|
||||||
usages. They include some support for static inference and local name
|
|
||||||
scopes. Furthermore, astroid can also build partial trees by inspecting living
|
|
||||||
objects.
|
|
||||||
|
|
||||||
|
|
||||||
Installation
|
|
||||||
------------
|
|
||||||
|
|
||||||

|
|
||||||
|
|
||||||
pip install .
|
|
||||||
|
|
||||||
|
|
||||||
If you want to do an editable installation, you can run::
|
|
||||||
|
|
||||||
pip install -e .

"""Python Abstract Syntax Tree New Generation
|
|
||||||
|
|
||||||
The aim of this module is to provide a common base representation of
|
|
||||||
python source code for projects such as pychecker, pyreverse,
|
|
||||||
pylint... Well, actually the development of this library is essentially
|
|
||||||
governed by pylint's needs.
|
|
||||||
|
|
||||||
It extends class defined in the python's _ast module with some
|
|
||||||
additional methods and attributes. Instance attributes are added by a
|
|
||||||
builder object, which can either generate extended ast (let's call
|
|
||||||
them astroid ;) by visiting an existent ast tree or by inspecting living
|
|
||||||
object. Methods are added by monkey patching ast classes.
|
|
||||||
|
|
||||||
Main modules are:
|
|
||||||
|
|
||||||
* nodes and scoped_nodes for more information about methods and
|
|
||||||
attributes added to different node classes
|
|
||||||
|
|
||||||
* the manager contains a high level object to get astroid trees from
|
|
||||||
source files and living objects. It maintains a cache of previously
|
|
||||||
constructed tree for quick access
|
|
||||||
|
|
||||||
* builder contains the class responsible to build astroid trees
