Colors layer
Table of ContentsClose
1 Description
This layer colors your life with:
- rainbow identifiers mode will colorize all identifiers (christmas tree mode :-)) with an almost unique color.
- color-identifiers mode will colorize only identifiers recognized as variables.
- rainbow mode displays strings representing colors with the color they represent as background.
- nyan mode display a Nyan cat progress bar in the mode-line.
2 Install
To use this configuration layer, add it to your ~/.spacemacs. You will need to
add colors to the existing dotspacemacs-configuration-layers list in this
file.
3 Configuration
3.1 Colorize identifiers
To colorize some identifiers by default in programming language buffers, set
the layer variables colors-colorize-identifiers to either variables or
all. variables will colorize only words recognized as variables, all
will colorize all the words.
(setq-default dotspacemacs-configuration-layers '( (colors :variables colors-colorize-identifiers 'all)))
When using the value all the Saturation and lightness of can be set per theme
by adding an entry in the variable colors-theme-identifiers-sat&light. This is
an alist where the key is a theme symbol and the value is a pair (saturation
lightness).
For now saturation and lightness are not supported with the variables value.
Example:
(push '(mytheme . (50 50)) colors-theme-identifiers-sat&light)
3.2 Enable Nyan cat
To enable the package nyan-mode set the variable
colors-enable-nyan-cat-progress-bar to t:
(setq-default dotspacemacs-configuration-layers '( (colors :variables colors-enable-nyan-cat-progress-bar t)))
It may be handy to enable it only in a GUI, you can do it by using a quasi-quoted list:
(setq-default dotspacemacs-configuration-layers =((colors :variables colors-enable-nyan-cat-progress-bar ,(display-graphic-p))))
4 Key bindings
The prefix associated with colors is C.
4.1 Colorize Identifiers
| Key Binding | Description |
|---|---|
SPC C a |
colorize all idendifiers in current buffer |
SPC C C-a |
globally colorize all idendifiers and all subsequent buffers |
SPC C v |
colorize all variables only in current buffer |
SPC C C-v |
globally colorize all variables only and all subsequent buffers |
The saturation and lightness of identifier colors can be adjusted live
when colorizing all the identifiers with the transient-state:
| Key Binding | Description |
|---|---|
SPC C i s |
initiate change saturation mini-mode |
SPC C i l |
initiate change lightness mini-mode |
+ |
increase the saturation or lightness |
- |
decrease the saturation or lightness |
= |
reset the saturation or lightness |
Any other key |
leave the change mini-mode |
