# Brainy theme
|
||||
|
||||
Simple colorful terminal prompt theme (inspired by a number of themes).
|
||||
|
||||
## Features
|
||||
|
||||
### Prompt Segments
|
||||
|
||||
- Username & Hostname
|
||||
- Current Directory
|
||||
- SCM Information
|
||||
- Battery Charge
|
||||
- Clock
|
||||
- Ruby Environment
|
||||
- Python Environment
|
||||
- Exit Code
|
||||
|
||||
### Others
|
||||
|
||||
- Indicator for cached `sudo` credential
|
||||
- `brainy` command for showing/hiding various prompt segments on-the-fly
|
||||
|
||||
## Configuration
|
||||
|
||||
Various prompt segments can be shown/hidden or modified according to your choice. There are two ways for doing that:
|
||||
|
||||
1. On-the-fly using `brainy` command
|
||||
2. Theme Environment Variables
|
||||
|
||||
### On-the-fly using `brainy` command
|
||||
|
||||
This theme provides a command for showing/hiding prompt segments.
|
||||
|
||||
`brainy show <segment>`
|
||||
|
||||
`brainy hide <segment>`
|
||||
|
||||
Tab-completion for this command is enabled by default.
|
||||
|
||||
Configuration specified by this command will only be applied to current and subsequent child shells.
|
||||
|
||||
### Theme Environment Variables
|
||||
|
||||
This is used for permanent settings that apply to all terminal sessions. You have to define the value of specific theme variables in your `bashrc` (or equivalent) file.
|
||||
|
||||
The name of the variables are listed below along with their default values.
|
||||
|
||||
#### User Information
|
||||
|
||||
Indicator for cached `sudo` credential (see `sudo` manpage for more information):
|
||||
|
||||
`THEME_SHOW_SUDO=true`
|
||||
|
||||
#### SCM Information
|
||||
|
||||
Information about SCM repository status:
|
||||
|
||||
`THEME_SHOW_SCM=true`
|
||||
|
||||
#### Ruby Environment
|
||||
|
||||
Ruby environment version information:
|
||||
|
||||
`THEME_SHOW_RUBY=false`
|
||||
|
||||
#### Python Environment
|
||||
|
||||
Python environment version information:
|
||||
|
||||
`THEME_SHOW_PYTHON=false`
|
||||
|
||||
#### Clock
|
||||
|
||||
`THEME_SHOW_CLOCK=true`
|
||||
|
||||
`THEME_CLOCK_COLOR=$bold_cyan`
|
||||
|
||||
Format of the clock (see `date` manpage for more information):
|
||||
|
||||
`THEME_CLOCK_FORMAT="%H:%M:%S"`
|
||||
|
||||
#### Battery Charge
|
||||
|
||||
Battery charge percentage:
|
||||
|
||||
`THEME_SHOW_BATTERY=false`
|
||||
|
||||
#### Exit Code
|
||||
|
||||
Exit code of the last command:
|
||||
|
||||
`THEME_SHOW_EXITCODE=true`
|
||||
|
||||
## Prompt Segments Order
|
||||
|
||||
Currently available prompt segments are:
|
||||
|
||||
- battery
|
||||
- char
|
||||
- clock
|
||||
- dir
|
||||
- exitcode
|
||||
- python
|
||||
- ruby
|
||||
- scm
|
||||
- user_info
|
||||
|
||||
Three environment variables can be defined to rearrange the segments order. The default values are:
|
||||
|
||||
`___BRAINY_TOP_LEFT="user_info dir scm"`
|
||||
|
||||
`___BRAINY_TOP_RIGHT="python ruby clock battery"`
|
||||
|
||||
`___BRAINY_BOTTOM="exitcode char"`
