# Advanced Configuration
|
|
|
|
While Starship is a versatile shell, sometimes you need to do more than edit
|
|
`starship.toml` to get it to do certain things. This page details some of the more
|
|
advanced configuration techniques used in starship.
|
|
|
|
::: warning
|
|
|
|
The configurations in this section are subject to change in future releases of Starship.
|
|
|
|
:::
|
|
|
|
## Custom pre-prompt and pre-execution Commands in Bash
|
|
|
|
Bash does not have a formal preexec/precmd framework like most other shells.
|
|
Because of this, it is difficult to provide fully customizable hooks in `bash`.
|
|
However, Starship does give you limited ability to insert your own functions
|
|
into the prompt-rendering procedure:
|
|
|
|
- To run a custom function right before the prompt is drawn, define a new
|
|
function and then assign its name to `starship_precmd_user_func`. For example,
|
|
to draw a rocket before the prompt, you would do
|
|
|
|
```bash
|
|
function blastoff(){
|
|
echo "🚀"
|
|
}
|
|
starship_precmd_user_func="blastoff"
|
|
```
|
|
|
|
- To run a custom function right before a command runs, you can use the
|
|
[`DEBUG` trap mechanism](https://jichu4n.com/posts/debug-trap-and-prompt_command-in-bash/).
|
|
However, you **must** trap the DEBUG signal *before* initializing Starship!
|
|
Starship can preserve the value of the DEBUG trap, but if the trap is overwritten
|
|
after starship starts up, some functionality will break.
|
|
|
|
```bash
|
|
function blastoff(){
|
|
echo "🚀"
|
|
}
|
|
trap blastoff DEBUG # Trap DEBUG *before* running starship
|
|
eval $(starship init bash)
|
|
```
|
|
|
|
## Change Window Title
|
|
|
|
Some shell prompts will automatically change the window title for you (e.g. to
|
|
reflect your working directory). Fish even does it by default.
|
|
Starship does not do this, but it's fairly straightforward to add this
|
|
functionality to `bash` or `zsh`.
|
|
|
|
First, define a window title change function (identical in bash and zsh):
|
|
|
|
```bash
|
|
function set_win_title(){
|
|
echo -ne "\033]0; YOUR_WINDOW_TITLE_HERE \007"
|
|
}
|
|
```
|
|
|
|
You can use variables to customize this title (`$USER`, `$HOSTNAME`, and `$PWD`
|
|
are popular choices).
|
|
|
|
In `bash`, set this function to be the precmd starship function:
|
|
|
|
```bash
|
|
starship_precmd_user_func="set_win_title"
|
|
```
|
|
|
|
In `zsh`, add this to the `precmd_functions` array:
|
|
|
|
```bash
|
|
precmd_functions+=(set_win_title)
|
|
```
|
|
|
|
If you like the result, add these lines to your shell configuration file
|
|
(`~/.bashrc` or `~/.zshrc`) to make it permanent.
|
|
|
|
For example, if you want to display your current directory in your terminal tab title,
|
|
add the following snippet to your `~/.bashrc` or `~/.zshrc`:
|
|
|
|
```bash
|
|
function set_win_title(){
|
|
echo -ne "\033]0; $(basename "$PWD") \007"
|
|
}
|
|
starship_precmd_user_func="set_win_title"
|
|
```
|
|
|
|
## Style Strings
|
|
|
|
Style strings are a list of words, separated by whitespace. The words are not case sensitive (i.e. `bold` and `BoLd` are considered the same string). Each word can be one of the following:
|
|
|
|
- `bold`
|
|
- `underline`
|
|
- `dimmed`
|
|
- `inverted`
|
|
- `bg:<color>`
|
|
- `fg:<color>`
|
|
- `<color>`
|
|
- `none`
|
|
|
|
where `<color>` is a color specifier (discussed below). `fg:<color>` and `<color>` currently do the same thing, though this may change in the future. `inverted` swaps the background and foreground colors. The order of words in the string does not matter.
|
|
|
|
The `none` token overrides all other tokens in a string if it is not part of a `bg:` specifier, so that e.g. `fg:red none fg:blue` will still create a string with no styling. `bg:none` sets the background to the default color so `fg:red bg:none` is equivalent to `red` or `fg:red` and `bg:green fg:red bg:none` is also equivalent to `fg:red` or `red`. It may become an error to use `none` in conjunction with other tokens in the future.
|
|
|
|
A color specifier can be one of the following:
|
|
|
|
- One of the standard terminal colors: `black`, `red`, `green`, `blue`,
|
|
`yellow`, `purple`, `cyan`, `white`. You can optionally prefix these
|
|
with `bright-` to get the bright version (e.g. `bright-white`).
|
|
- A `#` followed by a six-digit hexadecimal number. This specifies an
|
|
[RGB color hex code](https://www.w3schools.com/colors/colors_hexadecimal.asp).
|
|
- A number between 0-255. This specifies an [8-bit ANSI Color Code](https://i.stack.imgur.com/KTSQa.png).
|
|
|
|
If multiple colors are specified for foreground/background, the last one in the string will take priority.
