# Rainbow Bash Prompt
An extension for bash that generates a rainbow-colored PS1 with IP address shown as 4 blocks of color.

## Install with apt (ubuntu/debian)
### Add the repository
You can add the repository by running the following command:
```bash
sudo wget -O /usr/share/keyrings/soph-deb.gpg "https://cdn.sophuwu.com/deb/key.gpg" && echo 'deb [signed-by=/usr/share/keyrings/soph-deb.gpg] https://cdn.sophuwu.com/deb/ sophuwu main' | sudo tee /etc/apt/sources.list.d/sophdeb.list
```
This script will do the same thing:
```bash
curl https://cdn.sophuwu.com/deb/addrepo.sh | sudo sh
```
### Install the "bash-rb-ps1" package   
```bash
sudo apt update
sudo apt install bash-rb-ps1
```
## Run for the first time
This will only work if you are using bash with xterm-like escape sequences. You can enable the generator
by running:
```bash
eval $(bash-rb-ps1 help)
```
If you experience an error, or want to disable the prompt, you can run:
```bash
unset PROMPT_COMMAND
PS1='${debian_chroot:+($debian_chroot)}\u@\h:\w\$ '
```
To see help and other information about the command, use:
```bash
man bash-rb-ps1.1
```
## Compile from source
```bash
make
sudo install ./build/bashprompt /usr/local/bin/bash-rb-ps1
sudo install ./releaser/bash-rb-ps1.1 /usr/local/share/man/man1/bash-rb-ps1.1
```

## Options:
Environment variables can be set to customize the prompt.

### `IPCOLOR`
* Controls how the IP address is printed.
* `IPCOLOR=""` IP address will be colored with the default color palette.
* `IPCOLOR="alt"` IP address will be colored with an alternate color palette.
* `IPCOLOR="none"` IP address will not be printed.

### `PWDLEN`
* Controls the length of the printed working directory.
* `PWDLEN=0` Full path.
* `PWDLEN=1` Only the current directory.
* `PWDLEN=2` Current directory and its parent.

### `RBPSFMT`
* Controls the format of the prompt.
* Only valid format specifiers will be printed. Strings or invalid specifiers will be ignored.
* Default: `"%i %? %u %l %e %d"`
* Certain specifiers allow custom colours, to use them, put a number 0-255 after the `%` in the form `fg.bg` (`%32.240u`, `%.42l`, `%128d`).
* Format specifiers:
  * `%i` - IP address (4 blocks of color)
  * `%?` - Exit code of last command
  * `%u` - Username
  * `%h` - Hostname
  * `%l` - Line number
  * `%e` - Random emote (:D, :P, etc.)
  * `%d` - Current working directory (shortened according to `PWDLEN`)
