## Configuration
You can install mood-line directly via `package-install` from [MELPA](https://melpa.org/).
After installation, you can activate the global minor mode with `M-x mood-line-mode`.
Deactivating `mode-line-mode` will restore the default `mode-line-format`.
If you are a user of `use-package`, it is easy to configure mood-line directly in your init.el:
```elisp
(use-package mood-line
;; Enable mood-line
:config
(mood-line-mode)
;; Use pretty Fira Code-compatible glyphs
:custom
(mood-line-glyph-alist . mood-line-glyphs-fira-code))
```
### Format
mood-line uses a modular segment format, and it is easy to reconfigure:
```elisp
;; Default format:
;; * init.el 4:32 Top ELisp ! Issues: 2
(setq mood-line-format mood-line-format-default)
;; Extended format:
;; * init.el 4:32:52 Top SPCx2 LF UTF-8 ELisp ! Issues: 2
(setq mood-line-format mood-line-format-default-extended)
;; Custom format:
;; * init.el : ELisp Top 4:32 | ! Issues: 2
(setq mood-line-format
'(;; Left side
(" "
(mood-line-segment-buffer-status) " "
(mood-line-segment-buffer-name) " : "
(mood-line-segment-major-mode))
;; Right side
((mood-line-segment-scroll) " "
(mood-line-segment-cursor-position) " "
(when (mood-line-segment-checker) "|") " "
(mood-line-segment-checker) " "
" ")))
```
More information on the format specification is available in the documentation.
(`M-x describe-variable mood-line-format`)
### Glyphs
2022-12-22 11:12:01 +00:00
By default, mood-line will use basic ASCII character glyphs to decorate mode line segments.
If you'd like to see prettier Unicode glyphs, you can change the value of `mood-line-glyph-alist`:
```elisp
;; The default set of glyphs:
;; * myModifiedFile.js Replace*3 + main Javascript ! Issues: 2
(setq mood-line-glyph-alist mood-line-glyphs-ascii)
;; A set of Fira Code-compatible Unicode glyphs:
;; ● myModifiedFile.js Replace×3 + main JavaScript → Issues: 2
(setq mood-line-glyph-alist mood-line-glyphs-fira-code)
2019-04-12 07:37:02 +00:00
2022-12-22 11:12:01 +00:00
;; A set of Unicode glyphs:
;; ● myModifiedFile.js Replace✕3 🞤 main JavaScript ⚑ Issues: 2
(setq mood-line-glyph-alist mood-line-glyphs-unicode)
```

2022-12-22 11:12:01 +00:00
If you'd like to supply your own glyphs, you can use the customization interface
(`M-x customize-variable mood-line-glyph-alist`) or view the documentation
(`M-x describe-variable mood-line-glyph-alist`) for more information.

You can further tweak the behavior and appearance of mood-line by viewing the customizable variables
and faces in the `mood-line` and `mood-line-faces` customization groups. (`M-x customize-group mood-line`)
