2−------------
3−
4−nsxiv requires the following software to be installed:
5−
6− * Imlib2
7− * X11
8−
9−The following dependencies are optional.
10−
11− * `inotify`<sup>\*</sup>: Used for auto-reloading images on change.
12− Disabled via `HAVE_INOTIFY=0`.
13− * `libXft`, `freetype2`, `fontconfig`: Used for the status bar.
14− Disabled via `HAVE_LIBFONTS=0`.
15− * `giflib`: Used for animated gif playback.
16− Disabled via `HAVE_LIBGIF=0`.
17− * `libexif`: Used for auto-orientation and exif thumbnails.
18− Disable via `HAVE_LIBEXIF=0`.
19− * `libwebp`: Used for animated webp playback.
20− (***NOTE***: animated webp also requires Imlib2 v1.7.5 or above)
21− Disabled via `HAVE_LIBWEBP=0`.
22−
23−Please make sure to install the corresponding development packages in case that
24−you want to build nsxiv on a distribution with separate runtime and development
25−packages (e.g. \*-dev on Debian).
26−
27−\* [inotify][] is a Linux-specific API for monitoring filesystem changes.
28− It's not natively available on `*BSD` systems but can be enabed via installing
29− and linking against [libinotify-kqueue][].

35−Building
36−--------
37−
38−nsxiv is built using the commands:
39−
40− $ make
41−
42−You can pass `HAVE_X=0` to `make` to disable an optional dependency.
43−For example:
44−
45− $ make HAVE_LIBEXIF=0
46−
47−will disable `libexif` support. Alternatively they can be disabled via editing
48−`config.mk`. `OPT_DEP_DEFAULT=0` can be used to disable all optional
49−dependencies.
50−
51−Installing nsxiv:
52−
53− # make install
54−
55−Installing desktop entry:
56−
57− # make install-desktop
58−
59−Installing icons:
60−
61− # make install-icon
62−
63−Installing all of the above:
64−
65− # make install-all
66−
67−Please note, that these requires root privileges.
68−By default, nsxiv is installed using the prefix `/usr/local`, so the full path
69−of the executable will be `/usr/local/bin/nsxiv`, the `.desktop` entry will be
70−`/usr/local/share/applications/nsxiv.desktop` and the icon path will be
71−`/usr/local/share/icons/hicolor/{size}/apps/nsxiv.png`.
72−
73−You can install nsxiv into a directory of your choice by changing this command to:
74−
75− $ make PREFIX="/your/dir" install
76−
77−Example scripts are installed using `EGPREFIX` which defaults to
78−`/usr/local/share/doc/nsxiv/examples`. You can change `EGPREFIX` the same way
79−you can change `PREFIX` shown above.
80−
81−The build-time specific settings of nsxiv can be found in the file *config.h*.
82−Please check and change them, so that they fit your needs.
83−If the file *config.h* does not already exist, then you have to create it with
84−the following command:
85−
86− $ make config.h
87−
88−
89−Usage
90−-----
91−
92−Refer to the man-page for the documentation:
93−
94− $ man nsxiv
95−
96−You may also view the man-page [online](https://nsxiv.codeberg.page/man/).
97−However, note that the online man-page might not accurately represent your local
98−copy.

103−
104−* Can I open remote urls with nsxiv? <br>
105−Yes, see [nsxiv-url](https://codeberg.org/nsxiv/nsxiv-extra/src/branch/master/scripts/nsxiv-url)
106−
107−* Can I open all the images in a directory? <br>
108−Yes, see [nsxiv-rifle](https://codeberg.org/nsxiv/nsxiv-extra/src/branch/master/scripts/nsxiv-rifle)
109−
110−* Can I set default arguments for nsxiv? <br>
111−Yes, see [nsxiv-env](https://codeberg.org/nsxiv/nsxiv-extra/src/branch/master/scripts/nsxiv-env)
112−
113−* Can I pipe images into nsxiv? <br>
114−Yes, see [nsxiv-pipe](https://codeberg.org/nsxiv/nsxiv-extra/src/branch/master/scripts/nsxiv-pipe)
115−
116−You may also wish to see the [known issues](https://codeberg.org/nsxiv/nsxiv/issues/242).
117−
118−
119−Customization
120−-------------
121−
122−The main method of customizing nsxiv is by setting values for the variables in *config.h*,
123−or by using Xresources as explained in the manual. If these options are not sufficient,
124−you may implement your own features by following
125−[this guide](https://codeberg.org/nsxiv/nsxiv-extra/src/branch/master/CUSTOMIZATION.md).
126−
127−Due to our limited [project scope](etc/CONTRIBUTING.md#project-scope), certain features or
128−customization cannot be merged into nsxiv mainline. Following the spirit of suckless
129−software, we host the [nsxiv-extra](https://codeberg.org/nsxiv/nsxiv-extra) repo where users
130−are free to submit whatever patches or scripts they wish.
131−
132−If you think your custom features can be beneficial for the general user base and is within
133−our project scope, please submit it as a pull request on this repository, then we *may*
134−merge it to mainline.
135−
136−Description on how to use or submit patches can be found on
137−nsxiv-extra's [README](https://codeberg.org/nsxiv/nsxiv-extra).
