 --------------------------------------------------------------------
-nsxiv is a fork of the now-unmaintained [sxiv](https://github.com/xyb3rt/sxiv)
+fork of the famous [nsxiv](https://codeberg.org/nsxiv/nsxiv)
 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. If you're looking
 to migrate from `sxiv`, see [MIGRATION]. 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">

 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).

 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.

 # Migrating from `sxiv`
 `nsxiv` is *mostly* a drop-in replacement for `sxiv`, but not fully.
 This document outlines some key differences to be aware of if you're migrating
 from `sxiv`.
 ### Configuration directory
 `sxiv` looks for config files under the directory
 `${XDG_CONFIG_HOME:-${HOME}/.config}/sxiv`. E.g
 `~/.config/sxiv/exec/key-handler`.
 `nsxiv` uses the same logic to find the config dir but uses the name "nsxiv".
 E.g `~/.config/nsxiv/...`.
 The "exec" scripts such as `key-handler` and `image-info` in `nsxiv` has some
 more features, but all previous argument order are preserved. And so if you have
 any exec scripts, you can simply copy them over and they should just work.
 ### Xresources
 The xresources config for `nsxiv` is under the "Nsxiv" namespace whereas `sxiv`
 uses the "Sxiv" namespace. Some of the variables are also different between
 `nsxiv` and `sxiv`, below is a table that shows the old and new names:
 | sxiv                | nsxiv                    |
 | :--                 | :--                      |
 | Sxiv.background     | Nsxiv.window.background  |
 | Sxiv.foreground     | Nsxiv.window.foreground  |
 | Sxiv.barBackground  | Nsxiv.bar.background     |
 | Sxiv.barForeground  | Nsxiv.bar.foreground     |
 | Sxiv.font           | Nsxiv.bar.font           |
 ### Default window class
 The window class of `nsxiv` is set to "Nsxiv" by default (can be overwritten via
 `-N` flag). This usually shouldn't matter, unless you have scripts that search
 for "Sxiv" window class.
 ### Thumbnail cache directory
 Similar to config dir, the thumbnail cache dir of `nsxiv` is under the "nsxiv"
 name instead of "sxiv". E.g `~/.cache/nsxiv`.
 The "caching structure" in `nsxiv` is the same as `sxiv`. Which means that you
 can simply rename the directory to `nsxiv`:
 ```console
 $ mv  ~/.cache/sxiv  ~/.cache/nsxiv
 ```
 If you want to have both `sxiv` and `nsxiv` installed at the same time, you can
 even use symlink to avoid duplicate cache.

 ):
 .TP
 .B window.background
 Color of the window background
 .TP
 .B window.foreground
 Color of the window foreground
 .TP
 .B bar.font
 Name of Xft bar font
 .TP
 .B bar.background
 Color of the bar background. Defaults to window.background
 .TP
 .B bar.foreground
 Color of the bar foreground. Defaults to window.foreground
 .TP
 .B mark.foreground
 Color of the mark foreground. Defaults to window.foreground
 .TP
 Please see xrdb(1) on how to change them.
 .LP
 An X resources entry with an empty value means the default
 (defined in config.h) will be used.
 .SH WINDOW TITLE
 The window title can be replaced with the output of a user-provided script,
 which is called by nsxiv whenever any of the relevant information changes.
 The path of this script is
 .I $XDG_CONFIG_HOME/nsxiv/exec/win-title
 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
 The script that is called by nsxiv whenever an image gets loaded is located at
 .I $XDG_CONFIG_HOME/nsxiv/exec/image-info
 and the arguments given to it are:
 .IP $1 4
 path to image file (as provided by the user)
 .IP $2 4
 image width
 .IP $3 4
 image height
 .IP $4 4
 fully resolved path to the image file
 .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 {} \\;
 .RE
 .P
 The option
 .BR "\-\-cache\-allow " or " \-\-cache\-deny"
 may be used to whitelists or blacklist certain directories from being cached.
 The argument is a
 .B :
 separated list of paths. A
 .B *
 at the beginning of the path indicates that path should be matched recursively.
 .P
 For example:
 .B \-\-cache\-allow \(dq/user/pictures:*/media/pictures\(dq
 whitelists \(dq/user/pictures\(dq directory non-recursively and \(dq/media/pictures\(dq
 directory recursively. Nothing outside these two directories will be cached.
 And
 .B \-\-cache\-deny \(dq*/secret\(dq
 will enable blacklist mode and will not cache anything inside \(dq/secret\(dq
 or it's subdirectories.

 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.

In the first case, the help message should go to stdout. In the second case, it is an error, and should go to stderr.
