 1 | = Contributing
 2 | 
 3 | == Requirements
 4 | 
 5 | A basic knowledge of C is required for contributing to the core or for creating
 6 | widgets.
 7 | 
 8 | Knowledge of HTML, CSS and JS is required for contributing to candybar themes - see
 9 | the https://github.com/Lokaltog/candybar-theme-default[default candybar theme] for
10 | details.
11 | 
12 | == Making changes
13 | 
14 | You need to be comfortable with git. The project uses the
15 | http://nvie.com/posts/a-successful-git-branching-model/[git flow] branching model.
16 | 
17 | Create a topic branch from where you want to base your work. Most contributions
18 | should be based off the +develop+ branch. Prefix your branch with +feature/+ if
19 | you're working on a new feature.
20 | 
21 | Submit a pull request to
22 | https://github.com/Lokaltog/candybar/pulls[Lokaltog/candybar]. Please write good,
23 | descriptive commit messages, and prefix your changes with the part the commit applies
24 | to, e.g. +widgets/weather: Fix errors when compiling with optimizations+. See
25 | http://tbaggery.com/2008/04/19/a-note-about-git-commit-messages.html[Tim Pope's guide
26 | to commit messages].
27 | 
28 | === Coding style
29 | 
30 | The project uses a slightly modified BSD KNF coding style. It's recommended that you
31 | run +uncrustify+ with the config file provided in the project root on any modified or
32 | added C files before submitting a pull request.
33 | 
34 | == Project layout
35 | 
36 | All C source is located in +src/+. Every widget is located in a separate C file in
37 | +src/widgets/+. Common utility functions for logging, config loading, etc. are
38 | located in +src/util/+.
39 | 
40 | +src/candybar.c+:: Loads user config, initializes the web view, sets window
41 |     properties, etc.
42 | 
43 | +src/widgets.c+:: Handles widget threads and JSCore extensions and callbacks.
44 | 
45 | == Debug/development build
46 | 
47 | This is useful for development as it uses a relative library search path, so candybar
48 | doesn't have to be installed system-wide for widgets to work.
49 | 
50 | [source,sh]
51 | ----
52 | ./waf configure clean build install \    # <1>
53 |       --debug \                          # <2>
54 |       --prefix=/ \                       # <3>

60 | # ...
61 | 
62 | ./waf build install                      # <6>
63 | ----
64 | <1> the +configure+ and +clean+ actions are optional after the initial build
65 | <2> enable debug build (disable optimizations, enable debug logging)
66 | <3> disable prefixing the destination directory with +/usr/+
67 | <4> tell +candybar+ to search for the default theme and widget libraries in the +out/+ directory
68 | <5> installs into +out/+, remember to change +--libdir+ if you change this directory
69 | <5> rebuild project, this command only recompiles changed files and is very fast

11 | candybar - WebKit-based status bar for tiling window managers
12 | 
13 | Synopsis
14 | --------
15 | 
16 | *candybar* [*-d*] [*-c* _config-file_] [*-h* _height_] [*-m* _monitor_] [*-p*
17 |  _position_] [*-t* _theme-uri_]
18 | 
19 | Description
20 | -----------
21 | 
22 | *candybar* displays a HTML-based status bar in a WebKit web view. It provides a
23 | smooth looking status bar with CSS transitions and effects, and the possibility of
24 | having a transparent background with effects without a desktop compositor running.
25 | 
26 | Screenshots are available on the
27 | https://github.com/Lokaltog/candybar/wiki/Screenshots[candybar wiki].
28 | 
29 | Options
30 | -------
31 | 
32 | *-d*:: Enable debugging mode and display the WebKit inspector window on launch.
33 | 
34 | *-c* _config-file_:: Read configuration options from the specified
35 | _config-file_. config-file overrides _CANDYBAR_CONFIG_PATH_ and any system-wide and
36 | per-user configuration files. The file must exist and be valid JSON.
37 | 
38 | *-h* _height_:: Set the height of the status bar in pixels.
39 | 
40 | *-m* _monitor_:: Define which monitor the status bar appears on.
41 | 
42 | *-p* _position_:: Set the status bar position. Valid options are _top_ and _bottom_.
43 | 
44 | *-t* _theme-uri_:: Set the URI for a theme HTML file. Must be a valid URI, i.e. local
45 | files must be prefixed with _file://_.
46 | 
47 | Window manager support
48 | ----------------------
49 | 
50 | *bspwm*:: supported; requires bspwm to be configured to reserve space with _bspc
51 | config top_padding 24_.
52 | 
53 | *dwm*:: supported; requires the dwm built-in bar to be enabled and set to the same
54 | position and height as candybar, candybar will be placed on top of the dwm bar.
55 | 
56 | *i3*:: supported; desktop support requires the _desktops_i3_ widget to be enabled
57 | instead of the default _desktops_ widget for desktop list support.
58 | 
59 | *monsterwm*:: supported
60 | 
61 | *qtile*:: supported; requires a recent version, support for desktop EWMH properties
62 | was implemented in qtile revision 02fd471.
63 | 
64 | Files
65 | -----
66 | 
67 | _~/.config/candybar/config.json_:: Per-user configuration file. See *candybar*(5) for
68 | further details.
69 | 
70 | _/etc/xdg/candybar/config.json_:: System-wide configuration file. See *candybar*(5)
71 | for further details.
72 | 
73 | Environment

75 | 
76 | _CANDYBAR_CONFIG_PATH_:: Full path of an alternate _config.json_ file. This variable
77 | overrides any system-wide and per-user configuration files, but does not override the
78 | *-c* command-line argument. The file must exist and be valid JSON.
