# MINIMAL2

A minimal and extensible zsh theme. Forked from [subnixr's original](https://github.com/subnixr/minimal) and adapted for [Zimfw](https://github.com/zimfw/zimfw).

# Installation



1. Clone (or add as submodule) minimalzim to your `zimfw` modules directory:



```

cd ${ZIM_HOME}/modules; git clone https://github.com/PatTheMav/minimal2.git ./minimal2

```



2. Add `minimal2` to your `zmodules` inside your `.zshrc` (just before the `prompt` module).

3. Set the prompt theme by setting `zprompt_theme` to `minimal2`



# Changes from original `minimal.zsh`



* Additional support for `git-info` module to display git branch

* Additional colour for clean branches ahead or behind the remote branch

* Uses `prompt_opts` and seperate setup routine for `zimfw` compatibility



# Customization and extension

## Architecture

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)



## Override default settings

Different components can use these (global) settings:



- `MNML_OK_COLOR`: Color for successful things (default: `green`)

- `MNML_ERR_COLOR`: Color for failures (default: `red`)

- `MNML_DIV_COLOR`: Color for diverted git status (default: `magenta`)

- `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.



## Available components

### Status



> `λ`



**Syntax**: `mnml_status`



An indicator displaying the following information:

- user privilege: `#` is printed when root, `$MNML_USER_CHAR` otherwise.

- last command success: indicator's color is set to `$MNML_OK_COLOR` when the last command was successful, `$MNML_ERR_COLOR` otherwise.

- background jobs: indicator is underlined if at least one job is in background.



### Keymap



> `›`



**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`



### Current Working Directrory



> `~`



**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.



### Git branch status



> `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.



#### Using git-info



**Syntax**: `mnml_git_zimfw`



Same functionality as `mnml_git`, but uses zimfw's built-in `git-info` to display and style git information. Uses the additional `$MNML_DIV_COLOR` if the branch is ahead or behind the remote branch.



### User, Hostname & PWD



> `user@host:~`



**Syntax**: `mnml_uhp`



Displays the current username, hostname and working directory.



### SSH hostname



> `host`



**Syntax**: `mnml_ssh`



Displays the hostname only if current session is through a SSH connection.



### Python virtual environment



> `venv`



**Syntax**: `mnml_pyenv`



Displays the current activated python virtualenv.



### Last command error value



> `1`



**Syntax**: `mnml_err`



Displays the last command exit status only if it is not `0`.



### Background jobs counter



> `2&`



**Syntax**: `mnml_jobs`



Displays the number of background jobs only if there is at least one.



### Files



> `[5 (2)]`



**Syntax**: `mnml_files`



Displays the number of visible files, followed by the number of hidden files if any.



## Magic enter functions

### Directory stack



**Syntax**: `mnml_me_dirs`



Prints `dirs` output if there is more than `1` directory in the stack.



### Colored `ls`



**Syntax**: `mnml_me_ls`



Prints colored `ls` output.



### Condensed git status



**Syntax**: `mnml_me_git`



Prints a colored and concise `git status`, only when inside a git repo.



## Custom components



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 minimalplus.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.



# Configuration examples:

## no UTF-8



```

MNML_USER_CHAR='$'

MNML_NOMRAL_CHAR='-'

MNML_INSERT_CHAR='>'

source minimalplus.zsh

```



Result (right omitted): `$ >`



## classic bash's prompt



```

MNML_PROMPT=(mnml_uhp mnml_status mnml_keymap)

MNML_RPROMPT=()

source minimalplus.zsh

```



Result: `user@host:~ λ ›          `



## good old days



```

MNML_PROMPT=(mnml_status)

MNML_RPROMPT=()

MNML_INFOLN=()

MNML_MAGICENTER=()

source minimalplus.zsh

```



Result: `λ                        `
