A minimal and extensible zsh theme.
Zgen:
zgen load subnixr/minimal
antigen bundle subnixr/minimal
Otherwise, you can always clone the repo and source minimal.zsh.
Minimal is mostly a collection of components (shell functions) on top of a thin layer to ease customization.
There are 3 areas where a component can be rendered:
- left prompt
- right prompt
- infoline (shown when there is no command and user presses
Enter)
A component should work in any of the three areas (left, right, info)
Different components can use these (global) settings:
MNML_OK_COLOR: Color for successful things (default:2)MNML_ERR_COLOR: Color for failures (default:1)MNML_USER_CHAR: Character used for unprivileged users (default:λ)MNML_INSERT_CHAR: Character used for vi insert mode (default:›)MNML_NORMAL_CHAR: Character used for vi normal mode (default:·)
Three global arrays handle the definition and rendering position of the components:
# Components on the left prompt
MNML_PROMPT=(mnml_ssh mnml_pyenv mnml_status mnml_keymap)
# Components on the right prompt
MNML_RPROMPT=('mnml_cwd 2 0' mnml_git)
# Components shown on info line
MNML_INFOLN=(mnml_err mnml_jobs mnml_uhp mnml_files)
An additional array is used to configure magic enter's behavior:
MNML_MAGICENTER=(mnml_me_dirs mnml_me_ls mnml_me_git)
These values can be changed interactively or in any of the init files.
PROMPT and RPROMPT should be left untouched, as minimal already takes care of them.
λ
Syntax: mnml_status
An indicator displaying the following information:
- user privilege:
#is printed when root,$MNML_USER_CHARotherwise. - last command success: indicator's color is set to
$MNML_OK_COLORwhen the last command was successful,$MNML_ERR_COLORotherwise. - background jobs: indicator is underlined if at least one job is in background.
›
Syntax: mnml_keymap
An indicator displaying the current keymap. $MNML_INSERT_CHAR is printed when in insert or default mode, $MNML_NORMAL_CHAR when in normal (vi) mode.
It reacts to keymap changes. It should work even if zsh bind mode is not set to vi
~
Syntax: mnml_cwd N LEN
Displays the last N segments of the current working directory, each one trucated if LEN is exceded.
If N is not specified, it will take a default value of 2. If is specified but N <= 0, it will be set to 1.
If LEN is not specified or LEN <= 0 no truncation will be performed on the segments. If 0 < LEN < 4 it will be set to 4.
When a segment length is greater than LEN's value, the first LEN / 2 - 1 characters are printed, followed by .., followed by the last LEN / 2 - 1 characters.
For example, with LEN = 8 and 0123456789 as segment, 012..789 is displayed.
master
Syntax: mnml_git
Displays the current git's branch, when inside a git repo. Color is set to $MNML_OK_COLOR if the branch is clean, $MNML_ERR_COLOR if the branch is dirty.
user@host:~
Syntax: mnml_uhp
Displays the current username, hostname and working directory.
host
Syntax: mnml_ssh
Displays the hostname only if current session is through a SSH connection.
venv
Syntax: mnml_pyenv
Displays the current activated python virtualenv.
1
Syntax: mnml_err
Displays the last command exit status only if it is not 0.
2&
Syntax: mnml_jobs
Displays the number of background jobs only if there is at least one.
[5 (2)]
Syntax: mnml_files
Displays the number of visible files, followed by the number of hidden files if any.
Syntax: mnml_me_dirs
Prints dirs output if there is more than 1 directory in the stack.
Syntax: mnml_me_ls
Prints colored ls output.
Syntax: mnml_me_git
Prints a colored and concise git status, only when inside a git repo.
Adding functionality is as easy as writing a shell function and adding it to one of the arrays:
function awesome_component {
echo -n "AWESOME"
}
function awesome_magicenter {
figlet -f slant "COOL"
}
source minimal.zsh
MNML_PROMPT=(awesome_component $MNML_PROMPT)
MNML_MAGICENTER+=awesome_magicenter
Due to minimal's architecture, if you need the value of the last command exit status ($?), $MNML_LAST_ERR must be used. $? can still be used to check for errors inside the component.
MNML_USER_CHAR='$'
MNML_NOMRAL_CHAR='-'
MNML_INSERT_CHAR='>'
source minimal.zsh
