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
|
||||||
|
RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
|
||||||
|
FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), 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 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

|
||||||
|
|

|
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 Random Hacker.

Markdownify
|
||||||
|
===========
|
||||||
|
* handle non-markdownifiable lists (i.e. `<ul><li id="foobar">asdf</li></ul>`)
|
||||||
|
* organize methods better (i.e. flushlinebreaks & setlinebreaks close to each other)
|
||||||
|
* take a look at function names etc.
|
||||||
|
* is the new (in rev. 93) lastclosedtag property needed?
|
||||||
|
* word wrapping (some work is done but it's still very buggy)
|
||||||
|
|
||||||
|
|
||||||
|
Markdownify Extra
|
||||||
|
=================
|
||||||
|
|
||||||
|
* handle table alignment with KEEP_HTML=false
|
||||||
|
* handle tables without headings when KEEP_HTML=false is set
|
||||||
|
* handle Markdown inside non-markdownable tags
|
||||||
|
|
||||||
|
|
||||||
|
Implementation Thoughts
|
||||||
|
=======================
|
||||||
|
* non-markdownifiable lists and markdown inside non-markdownable tags as well as the current
|
||||||
|
table implementation could be rewritten by using a rollback mechanism.
|
||||||
|
|
||||||
|
example:
|
||||||
|
|
||||||
|
<ul><li>asdf</li><li id="foobar">asdf</li></ul>
|
||||||
|
|
||||||
|
we come to `<ul>`, know that this might fail and create a snapshot of our current parser
|
||||||
|
we keep on parsing and when we reach `<li id="foobar">` we gotta rollback and keep this
|
||||||
|
list in HTML format.
