+Powerline Gitstatus
+===================
+
+A [Powerline][1] segment for showing the status of a Git working copy.
+
+By [Jasper N. Brouwer][2].
+
+It will show the branch-name, or the commit hash if in detached head state.
+
+It will also show the number of commits behind, commits ahead, staged files,
+unmerged files (conflicts), changed files, untracked files and stashed files
+if that number is greater than zero.
+
+![screenshot][4]
+
+Glossary
+--------
+- ``: branch name or commit hash
+- `★`: most recent tag (if enabled)
+- `↓`: n commits behind
+- `↑`: n commits ahead
+- `●`: n staged files
+- `✖`: n unmerged files (conflicts)
+- `✚`: n changed files
+- `…`: n untracked files
+- `⚑`: n stashed files
+
+Requirements
+------------
+
+The Gitstatus segment requires [git][5]! Preferably, but not limited to, version 1.8.5 or higher.
+
+Version 1.8.5 will enable the usage of the `-C` parameter, which is more performant and accurate.
+
+Installation
+------------
+
+### On Debian/Ubuntu
+
+```txt
+apt install powerline-gitstatus
+```
+
+This command will also instruct your package manager to install Powerline, if it's not already available.
+
+Powerline will be automatically configured to use the Gitstatus highlight groups and add the segment to the default
+shell theme.
+
+### Using pip
+
+```txt
+pip install powerline-gitstatus
+```
+
+Configuration
+-------------
+
+The Gitstatus segment uses a couple of custom highlight groups. You'll need to define those groups in your colorscheme,
+for example in `.config/powerline/colorschemes/default.json`:
+
+```json
+{
+ "groups": {
+ "gitstatus": { "fg": "gray8", "bg": "gray2", "attrs": [] },
+ "gitstatus_branch": { "fg": "gray8", "bg": "gray2", "attrs": [] },
+ "gitstatus_branch_clean": { "fg": "green", "bg": "gray2", "attrs": [] },
+ "gitstatus_branch_dirty": { "fg": "gray8", "bg": "gray2", "attrs": [] },
+ "gitstatus_branch_detached": { "fg": "mediumpurple", "bg": "gray2", "attrs": [] },
+ "gitstatus_tag": { "fg": "darkcyan", "bg": "gray2", "attrs": [] },
+ "gitstatus_behind": { "fg": "gray10", "bg": "gray2", "attrs": [] },
+ "gitstatus_ahead": { "fg": "gray10", "bg": "gray2", "attrs": [] },
+ "gitstatus_staged": { "fg": "green", "bg": "gray2", "attrs": [] },
+ "gitstatus_unmerged": { "fg": "brightred", "bg": "gray2", "attrs": [] },
+ "gitstatus_changed": { "fg": "mediumorange", "bg": "gray2", "attrs": [] },
+ "gitstatus_untracked": { "fg": "brightestorange", "bg": "gray2", "attrs": [] },
+ "gitstatus_stashed": { "fg": "darkblue", "bg": "gray2", "attrs": [] },
+ "gitstatus:divider": { "fg": "gray8", "bg": "gray2", "attrs": [] }
+ }
+}
+```
+
+Then you can activate the Gitstatus segment by adding it to your segment configuration,
+for example in `.config/powerline/themes/shell/default.json`:
+
+```json
+{
+ "function": "powerline_gitstatus.gitstatus",
+ "priority": 40
+}
+```
+
+The Gitstatus segment will use the `-C` argument by default, but this requires git 1.8.5 or higher.
+
+If you cannot meet that requirement, you'll have to disable the usage of `-C`.
+Do this by passing `false` to the `use_dash_c` argument, for example in `.config/powerline/themes/shell/__main__.json`:
+
+```json
+"gitstatus": {
+ "args": {
+ "use_dash_c": false
+ }
+}
+```
+
+Optionally, a tag description for the current branch may be displayed using the `show_tag` option. Valid values for this
+argument are:
+ * `last` : shows the most recent tag
+ * `annotated` : shows the most recent annotated tag
+ * `contains` : shows the closest tag that comes after the current commit
+ * `exact` : shows a tag only if it matches the current commit
+You can enable this by passing one of these to the `show_tag` argument, for example in `.config/powerline/themes/shell/__main__.json`:
+
+```json
+"gitstatus": {
+ "args": {
+ "show_tag": "exact"
+ }
+}
+```
+Git is executed an additional time to find this tag, so it is disabled by default.
+
+Note: before v1.3.0, the behavior when the value is `True` was `last`. As of v1.3.0 onwards, `True` behaves as `exact`.
+
+Optionally the format in which Gitstatus shows information can be customized.
+This allows to use a different symbol or remove a fragment if desired. You can
+customize string formats for _tag_, _behind_, _ahead_, _staged_, _unmerged_,
+_changed_, _untracked_ and _stash_ fragments with the following arguments in a
+theme configuration file, for example `.config/powerline/themes/shell/__main__.json`:
+
+```json
+"gitstatus": {
+ "args": {
+ "formats": {
+ "tag": " {}",
+ "behind": " {}",
+ "ahead": " {}",
+ "staged": " {}",
+ "unmerged": " {}",
+ "changed": " {}",
+ "untracked": " {}",
+ "stashed": " {}"
+ }
+ }
+}
+```
+
+By default, when in detached head state (current revision is not a branch tip), Gitstatus shows a short commit hash in
+place of the branch name. This can be replaced with a description of the closest reachable ref using the
+`detached_head_style` argument, for example in `.config/powerline/themes/shell/__main__.json`:
+
+```json
+"gitstatus": {
+ "args": {
+ "detached_head_style": "ref"
+ }
+}
+```
