# Theme Guide for F-Sy-H
|
|
|
|
`fast-theme` tool is used to select a theme. There are 6 shipped themes, they can be listed with `fast-theme -l`.
|
|
Themes are basic [INI files](https://github.com/zdharma/fast-syntax-highlighting/tree/master/themes) where each
|
|
key is a *style*.
|
|
Besides shipped themes, user can point this tool to any other theme, by simple `fast-theme ~/mytheme.ini`. To
|
|
obtain template to work on when creating own theme, issue `fast-theme --copy-shipped-theme {theme-name}`.
|
|
|
|
To alter just a few styles and not create a whole new theme, use **overlay**. What is overlay? It is in the same
|
|
format as full theme, but can have only a few styles defined, and these styles will overwrite styles in main-theme.
|
|
Example overlay file:
|
|
|
|
```ini
|
|
; overlay.ini
|
|
[base]
|
|
commandseparator = yellow,bold
|
|
comment = 17
|
|
|
|
[command-point]
|
|
function = green
|
|
command = 180
|
|
```
|
|
|
|
File name `overlay.ini` is treated specially.
|
|
|
|
When specifing path, following short-hands can be used:
|
|
|
|
```
|
|
XDG: = ~/.config/fsh (respects $XDG_CONFIG_HOME env var)
|
|
LOCAL: = /usr/local/share/fsh/
|
|
HOME: = ~/.fsh/
|
|
OPT: = /opt/local/share/fsh/
|
|
```
|
|
|
|
So for example, issue `fast-theme XDG:overlay` to load `~/.config/fsh/overlay.ini` as overlay. The `.ini`
|
|
extension is optional.
|
|
|
|
## Secondary Theme
|
|
|
|
Each theme has key `secondary`, e.g. for theme `free`:
|
|
|
|
```ini
|
|
; free.ini
|
|
[base]
|
|
default = none
|
|
unknown-token = red,bold
|
|
; ...
|
|
; ...
|
|
; ...
|
|
secondary = zdharma
|
|
```
|
|
|
|
Secondary theme (`zdharma` in the example) will be used for highlighting of argument for `eval`
|
|
and of `$( ... )` interior (i.e. of interior of command substitution). Basically, recursive
|
|
highlighting uses alternate theme to make the highlighted code distinct:
|
|
|
|
|
|
|
|
In the above screen-shot the interior of `$( ... )` uses different colors than the rest of the
|
|
code. Example for `eval`:
|
|
|
|
|
|
|
|
First line doesn't use recursive highlighting, highlights `eval` argument as regular string.
|
|
Second line switches theme to `zdharma` and does full recursive highlighting of eval argument.
|
|
|
|
## Custom Working Directory
|
|
|
|
Set `$FAST_WORK_DIR` before loading the plugin to have e.g. processed theme files (ready to
|
|
load, in Zsh format, not INI) kept under specified location. This is handy if e.g. you install
|
|
Fast-Syntax-Highlighting system-wide (e.g. from AUR on ArchLinux) and want to have per-user
|
|
theme setup.
|
|
|
|
You can use "~" in the path, e.g. `FAST_WORK_DIR=~/.fsh` and also the `XDG:`, `LOCAL:`, `OPT:`,
|
|
etc. short-hands, so e.g. `FAST_WORK_DIR=XDG` or `FAST_WORK_DIR=XDG:` is allowed (in this case
|
|
it will be changed to `$HOME/.config/fsh` by default by F-Sy-H loader).
