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.
<signature of Ty Coon>, 1 April 1989
Ty Coon, President of Vice
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
Public License instead of this License.

**Neo (or New or Not) Simple (or Small or Suckless) X Image Viewer**
--------------------------------------------------------------------
nsxiv is a fork of the now-unmaintained [sxiv](https://github.com/xyb3rt/sxiv)
with the purpose of being a (mostly) drop-in replacement for sxiv, maintaining its
interface and adding simple, sensible features. nsxiv is free software licensed
under GPL-2.0-or-later and aims to be easy to modify and customize.
Please file a bug report if something does not work as documented or expected on
[Codeberg] after making sure you are using the latest release. Contributions
are welcome, see [CONTRIBUTING] to get started.

Installing via package manager
------------------------------
<a href="https://repology.org/project/nsxiv/versions">
<img align="right" width="192" src="https://repology.org/badge/vertical-allrepos/nsxiv.svg">
</a>
nsxiv is available on the following distributions/repositories. If you don't see
your distro listed here, either contact your distro's package maintainer or
consider packaging it yourself and adding it to the respective community repo.
Dependencies
------------
nsxiv requires the following software to be installed:
* X11
* Imlib2 (built with X11 support)
The following dependencies are optional:
* `inotify`<sup>\*</sup>: Used for auto-reloading images on change.
Disabled via `HAVE_INOTIFY=0`.
* `libXft`, `freetype2`, `fontconfig`: Used for the status bar.
Disabled via `HAVE_LIBFONTS=0`.
* `libexif`: Used for auto-orientation and exif thumbnails.
Disable via `HAVE_LIBEXIF=0`.
Please make sure to install the corresponding development packages in case that
you want to build nsxiv on a distribution with separate runtime and development
packages (e.g. \*-dev on Debian).
\* [inotify][] is a Linux-specific API for monitoring filesystem changes.
It's not natively available on `*BSD` systems but can be enabled via
installing and linking against [libinotify-kqueue][].
[inotify]: https://www.man7.org/linux/man-pages/man7/inotify.7.html
[libinotify-kqueue]: https://github.com/libinotify-kqueue/libinotify-kqueue
Building
--------
nsxiv is built using the commands:
$ make
You can pass `HAVE_X=0` to `make` to disable an optional dependency.
For example:
$ make HAVE_LIBEXIF=0
will disable `libexif` support. Alternatively they can be disabled via editing
`config.mk`. `OPT_DEP_DEFAULT=0` can be used to disable all optional
dependencies.
Installing nsxiv:
# make install
Installing desktop entry:
# make install-desktop
Installing icons:
# make install-icon
Installing all of the above:
# make install-all
Please note, that these requires root privileges.
By default, nsxiv is installed using the prefix `/usr/local`, so the full path
of the executable will be `/usr/local/bin/nsxiv`, the `.desktop` entry will be
`/usr/local/share/applications/nsxiv.desktop` and the icon path will be
`/usr/local/share/icons/hicolor/{size}/apps/nsxiv.png`.
You can install nsxiv into a directory of your choice by changing this command to:
$ make PREFIX="/your/dir" install
Example scripts are installed using `EGPREFIX` which defaults to
`/usr/local/share/doc/nsxiv/examples`. You can change `EGPREFIX` the same way
you can change `PREFIX` shown above.
The build-time specific settings of nsxiv can be found in the file *config.h*.
Please check and change them, so that they fit your needs.
If the file *config.h* does not already exist, then you have to create it with
the following command:
$ make config.h
Usage
-----
Refer to the man-page for the documentation:
$ man nsxiv
You may also view the man-page [online](https://nsxiv.codeberg.page/man/).
However, note that the online man-page might not accurately represent your local
copy.
F.A.Q.
------
* Can I open remote urls with nsxiv? <br>
Yes, see [nsxiv-url](https://codeberg.org/nsxiv/nsxiv-extra/src/branch/master/scripts/nsxiv-url)
* Can I open all the images in a directory? <br>
Yes, see [nsxiv-rifle](https://codeberg.org/nsxiv/nsxiv-extra/src/branch/master/scripts/nsxiv-rifle)
* Can I set default arguments for nsxiv? <br>
Yes, see [nsxiv-env](https://codeberg.org/nsxiv/nsxiv-extra/src/branch/master/scripts/nsxiv-env)
* Can I pipe images into nsxiv? <br>
Yes, see [nsxiv-pipe](https://codeberg.org/nsxiv/nsxiv-extra/src/branch/master/scripts/nsxiv-pipe)
You may also wish to see the [known issues](https://codeberg.org/nsxiv/nsxiv/issues/242).
Customization
-------------
The main method of customizing nsxiv is by setting values for the variables in *config.h*,
or by using Xresources as explained in the manual. If these options are not sufficient,
you may implement your own features by following
[this guide](https://codeberg.org/nsxiv/nsxiv-extra/src/branch/master/CUSTOMIZATION.md).
Due to our limited [project scope](etc/CONTRIBUTING.md#project-scope), certain features or
customization cannot be merged into nsxiv mainline. Following the spirit of suckless
software, we host the [nsxiv-extra](https://codeberg.org/nsxiv/nsxiv-extra) repo where users
are free to submit whatever patches or scripts they wish.
If you think your custom features can be beneficial for the general user base and is within
our project scope, please submit it as a pull request on this repository, then we *may*
merge it to mainline.
Description on how to use or submit patches can be found on
nsxiv-extra's [README](https://codeberg.org/nsxiv/nsxiv-extra).
Download
--------
You can [browse](https://codeberg.org/nsxiv/nsxiv) the source code repository
on Codeberg or get a copy using git with the following command:
$ git clone https://codeberg.org/nsxiv/nsxiv.git
You can view the changelog [here](etc/CHANGELOG.md)

***SPECIAL NOTE***: Due to [this incident](https://codeberg.org/nsxiv/nsxiv-tmp/issues/1)
we have moved development over to [Codeberg](https://codeberg.org/nsxiv/nsxiv).
A lot of the references *below* may now be 404 on GitHub. Any threads which
survived the wipe have been migrated over to [nsxiv-record]. All of the
references *above* can be found on the new main nsxiv repository on Codeberg.

Project Scope
-------------
* Bug fixes and maintenance
* Prioritize extensibility and simplicity
* Do not make the codebase more complex, keep it simple to hack on
* Do not add extra dependency (if we do, add compile time switch to disable it)
* New features may be added if it cannot be achieved (easily) via a shell script,
doesn't break backwards compatibility and doesn't violate any of the above rules.
Note: Since we aim to be a drop-in replacement for sxiv, we intend to keep all
sxiv's behaviors/features even in cases where removing them would make the
code-base simpler.
Also note that (n)sxiv uses `imlib2` for loading images. Thus any request or
patches for adding support for new image formats should go into
[imlib2's repo](https://git.enlightenment.org/old/legacy-imlib2) instead.
Contribution Guideline
----------------------
When contributing, make sure:
* Your contribution falls under nsxiv's scope and aim
* You follow the existing code style (see the "Code Style" section below)
* You open the pull request from a new branch, not from master
* To avoid using force pushes, especially for bigger patches. Only use them
when there's merge conflicts.
If your contribution is not suitable for general use, it will not be included in nsxiv.
For changes that are very much up to preference, such as changing values in config.h,
please do not open a pull request unless you have an objective explanation.
See the [open issues](https://codeberg.org/nsxiv/nsxiv/issues) to find something
to work on. You can also filter the issues via label:
* [Good first issue](https://codeberg.org/nsxiv/nsxiv/issues?labels=49698):
(Easy) Issues which do not require much if any experience.
* [Up for grabs](https://codeberg.org/nsxiv/nsxiv/issues?labels=49705):
(Intermediate) Issues which are free for anyone who wants to pick it up.
Might require some experience.
* [Help wanted](https://codeberg.org/nsxiv/nsxiv/issues?labels=49699):
(Intermediate/Experienced) Issues where we require some help.
Code Style
----------
`nsxiv` mostly follows the [suckless code-style][sl], with a few exceptions.
If your editor supports [.editorconfig](../.editorconfig) then you'll already be
off to a good start without needing much manual intervention. Additionally we
provide a [clang-format](./.clang-format) configuration for reference, which you
may use via [`git-clang-format`][cf] to format the changes you've made (please
do not run it globally on the entire code-base since clang-format gets a decent
amount of edge cases wrong).
[sl]: https://suckless.org/coding_style/
[cf]: https://clang.llvm.org/docs/ClangFormat.html#git-integration
Development workflow for maintainers
------------------------------------
If we notice you contributing and/or showing interest in issues/pull requests,
we may invite you to join the nsxiv org as a member. Being a member simply means
you will be able to approve, disapprove and merge pull requests.
Our workflow regarding pull requests is the following:
* Code related changes require two approvals, but documentation related
changes (e.g. typo) can be merged with just one.
* If a pull request has a single approval, no objections and has been open
for more than 7 days, then it may be force-merged.
* Always prefer squashing when merging. In the case a PR makes more than one
significant change, use the "don't squash" tag and rebase instead.
* When merging, make sure the commit message is cleaned up properly so that
it reflects the current intention of the PR.
For releases, the process is the following:
* Tag the release with a "vN" tag, where N is the version number. Also set
the commit message and tag description for the release commit to "Release
version N". Make sure to use an annotated tag.
* Update `VERSION` macro in `config.mk`.
* Update the changelog (`etc/CHANGELOG.md`):
* Include link to the release tarball and add the release date.
* Document only the changes or fixes between releases. Don't document
changes which never made it into a release.
* Use the "Changes" section to document behavior changes since the last
release, the "Added" section for new features, and the "Fixes" section
for fixed bugs or regressions.
* Include pull request IDs with reference style links.
Mirroring to GitHub:
Assuming `origin` is the name of the codeberg remote and `github` is the name
of the github remote; run the following commands to mirror the codeberg repo to
github:
```console
$ git fetch --prune origin
$ git push --prune github '+refs/remotes/origin/*:refs/heads/*' '+refs/tags/*:refs/tags/*'
```
The first command updates the local repo and the second command pushes
everything on `origin` without pushing any of the local branches.

For mundane development related talks which don't warrant their own issue, use
the [general discussion](https://codeberg.org/nsxiv/nsxiv/issues/294) thread.

and the arguments given to it (where "Optional" arguments might be empty) are:
.IP $1 4
resolved absolute path of the current file
.IP $2 4
current file number
.IP $3 4
total file count
.IP $4 4
image width (Optional: Disabled on thumbnails mode)
.IP $5 4
image height (Optional: Disabled on thumbnails mode)
.IP $6 4
current zoom (Optional: Disabled on thumbnails mode)
.P
The term file is used rather than image as nsxiv does not precheck that the
input files are valid images. Total file count may be different from the actual
count of valid images.
.P
There is also an example script installed together with nsxiv as
.IR EGPREFIX/win-title .
.SH STATUS BAR
The information displayed on the left side of the status bar can be replaced
with the output of user-provided script.

.P
In thumbnail mode, the script that is called is located at
.I $XDG_CONFIG_HOME/nsxiv/exec/thumb-info
and the arguments given to it are:
.IP $1 4
path to image file (as provided by the user)
.IP $2 4
empty
.IP $3 4
empty
.IP $4 4
fully resolved path to the image file
.P
There are also example scripts installed together with nsxiv as
.IR EGPREFIX/image-info
and
.IR EGPREFIX/thumb-info .
.SH EXTERNAL KEY HANDLER
Additional external keyboard commands can be defined using a handler program
located in
.IR $XDG_CONFIG_HOME/nsxiv/exec/key-handler .
The handler is invoked by pressing
.BR Ctrl-x .
The next key combo is passed as its first argument. Passed via stdin are the
images to act upon: all marked images, if in thumbnail mode and at least one
image has been marked, otherwise the current image. nsxiv(1) will block until
the handler terminates. It then checks which images have been modified and
reloads them.
By default nsxiv(1) will send one image per-line to stdin, however when using
\-0 the image list will be NULL separated and the environment variable
"$NSXIV_USING_NULL" will be set to 1.
The key combo argument has the following form: "[C-][M-][S-]KEY",
where C/M/S indicate Ctrl/Meta(Alt)/Shift modifier states and KEY is the X
keysym as listed in /usr/include/X11/keysymdef.h without the "XK_" prefix.
If KEY has an uppercase equivalent, S-KEY is resolved into it. For instance,
K replaces S-k and Scedilla replaces S-scedilla, but S-Delete is sent as-is.
There is also an example script installed together with nsxiv as
.IR EGPREFIX/key-handler .
.SH THUMBNAIL CACHING
nsxiv stores all thumbnails under
.IR $XDG_CACHE_HOME/nsxiv/ .
.P
Use the command line option
.I \-c
to remove all orphaned cache files. Additionally, run the following command
afterwards inside the cache directory to remove empty subdirectories:
.P
.RS
find . \-depth \-type d \-empty ! \-name '.' \-exec rmdir {} \\;

img2data
--------
img2data is a helper program to convert images to binary data for embedding in
software. The generated data is used in nsxiv to set the window icons.
How It Works
------------
Each given image is compressed using run-length encoding and a data array is
generated. In these arrays, the four high bits of each byte are the run length
minus one and the lowest four bits are the data, which are indices for the
color array.
See `data.gen.h` or the output of img2data for a better understanding.
Dependencies
------------
img2data requires Imlib2 to be installed.
Building
--------
img2data is built using the command:
$ CC -Wall -std=c89 -pedantic -lImlib2 img2data.c -o img2data
where `CC` is a C compiler such as `gcc`.
Usage
-----
img2data is used as the following:
$ ./img2data 16x16.png 32x32.png 48x48.png 64x64.png 128x128.png
You may replace or omit any image, but you must have a `data.gen.h` with at
least 1 image for nsxiv to compile.

/* Optparse --- portable, reentrant, embeddable, getopt-like option parser
*
* This is free and unencumbered software released into the public domain.
*
* To get the implementation, define OPTPARSE_IMPLEMENTATION.
* Optionally define OPTPARSE_API to control the API's visibility
* and/or linkage (static, __attribute__, __declspec).
*
* The POSIX getopt() option parser has three fatal flaws. These flaws
* are solved by Optparse.
*
* 1) Parser state is stored entirely in global variables, some of
* which are static and inaccessible. This means only one thread can
* use getopt(). It also means it's not possible to recursively parse
* nested sub-arguments while in the middle of argument parsing.
* Optparse fixes this by storing all state on a local struct.
*
* 2) The POSIX standard provides no way to properly reset the parser.
* This means for portable code that getopt() is only good for one
* run, over one argv with one option string. It also means subcommand
* options cannot be processed with getopt(). Most implementations
* provide a method to reset the parser, but it's not portable.
* Optparse provides an optparse_arg() function for stepping over
* subcommands and continuing parsing of options with another option
* string. The Optparse struct itself can be passed around to
* subcommand handlers for additional subcommand option parsing. A
* full reset can be achieved by with an additional optparse_init().
*
* 3) Error messages are printed to stderr. This can be disabled with
* opterr, but the messages themselves are still inaccessible.
* Optparse solves this by writing an error message in its errmsg
* field. The downside to Optparse is that this error message will
* always be in English rather than the current locale.
*
* Optparse should be familiar with anyone accustomed to getopt(), and
* it could be a nearly drop-in replacement. The option string is the
* same and the fields have the same names as the getopt() global
* variables (optarg, optind, optopt).
*
* Optparse also supports GNU-style long options with optparse_long().
* The interface is slightly different and simpler than getopt_long().
*
* By default, argv is permuted as it is parsed, moving non-option
* arguments to the end. This can be disabled by setting the `permute`
* field to 0 after initialization.
