Wish

A customizable, extensible, themable bash prompt.

Features

  • Extensible: Parts can be added using simple plugins.
  • Themable: Choose from an existing theme or create your own.
  • Customizable: The prompt can be customized via a simple config file.
  • Right Prompt: Allows for two prompts — one on left, one on right.
  • Auto newline: Automatically adds a newline if the last output doesn't end with one.
  • Powerline support: Supports powerline symbols in both prompts.

Installation

One step Installation

curl https://gitlab.com/ceda_ei/wish/raw/master/install.sh | bash

Manual Installation

  • cd ~/.config/
  • git clone https://gitlab.com/ceda_ei/wish.git
  • cp wish/config.default.gie wish/config.gie

Customization

Customization of wish is done using a gINIe file (format specific to wish) which is an extended INI config file. The default location for config file is ~/.config/wish/config.gie. The default config file is automatically copied over. The location can be customized using WISH_CONFIG_FILE variable. Multiple config files can be supplied as an array to WISH_CONFIG_FILE.

Comments start with a # or ; and always exist on a line of their own.

Key value pairs are in the form of key = value. Keys cannot have whitespaces or = in them. Values can have any character as part of them. Surrounding spaces in values are stripped away. To keep surrounding spaces as a part of the value. Although, keys are case-sensitive in gINIe, wish treats them case- insensitively.

Block names are enclosed in [] (e.g. [core]). Block names are case sensitive. All key value pairs after a block starts and before the next block begins are considered a part of that block. All key value pairs must be in a block.

Available Blocks:

  • core: Core block configures Wish itself. Available keys are:
    • auto_newline: Automatically add a newline if last line of output doesn't end in newline. (0 to disable, 1 to enable)
    • theme: Wish theme.
    • powerline: Enable / Disable powerline. (0 to disable, 1 to enable)
  • plugin: Adds a plugin to the section the block is added to. All config for that plugin goes there. Check wiki for details on available keys for plugins. The key "name" defines the plugin to use. Plugin blocks outside a section are ignored.

Section names are enclosed in || (e.g. |left|). All blocks after a section starts and before the next section begins are considered a part of that section. Blocks don't necessarily need to be in a section.

Available sections are left, right for left prompt and right prompt respectively.

Sample config file

[core]
auto_newline = 1
powerline = 1
theme = rgb_gradient

|left|
[plugin]
name = path_powerline
max_perc = 50

[plugin]
name = python_venv

[plugin]
name = newline

[plugin]
name = custom_text
text = ' λ '

[plugin]
name = space

|right|
[plugin]
name = date
format = %a %b %H:%M

[plugin]
name = hostname

Which results in the following prompt
