alien-minimal

alien-minimal theme is faster than many other themes.

Why? It updates part of the prompt asynchronously – the time-consuming processing like git status checking, git dirty copy checking and so on

How? It starts a background job for these processes, and in the meantime shows initial prompt and lets you use the terminal as you would normally.

alien-minimal is independent of any library/framework like Oh-My-Zsh or Prezto.

Installation

Add the following line in ~/.zshrc depending on zsh plugin manager

antigen:
antigen theme eendroroy/alien-minimal alien-minimal
zgen:
zgen load eendroroy/alien-minimal
zplug:
zplug "eendroroy/alien-minimal"
oh-my-zsh: Overriding and Adding Themes
# if using git 2.13 or higher
git clone --recurse-submodules https://github.com/eendroroy/alien-minimal.git ${ZSH_CUSTOM}/themes/alien-minimal

# if lower version use
cd ${ZSH_CUSTOM}/themes/alien-minimal
git clone https://github.com/eendroroy/alien-minimal.git
git submodule update --init --recursive # --remote

Then set ZSH_THEME="alien-minimal/alien-minimal" in the ~/.zshrc file.

Customizations

add configurations in ~/.amrc

Sections

Available sections:

am_vcs_prompt configuration

Git:

Mercurial:

Subversion:

A sample sensible configuration

AM_VERSIONS_PROMPT=()

AM_GIT_SECTION=(
  am_git_symbol
  am_git_rebasing
  am_git_branch
  am_git_left_right_master
  am_git_commit_time
  am_git_rev
  am_git_stash
  am_git_left_right
  am_git_dirty
)

AM_HG_SECTION=(
  am_hg_symbol
  am_hg_branch
  am_hg_rev
)

AM_SVN_SECTION=(
  am_svn_symbol
  am_svn_rev
)

AM_LEFT_SECTION=(
  am_space
  am_ssh_st
  am_prompt_start_tag
  am_prompt_dir
  am_prompt_end_tag
  am_venv
  am_space
)

AM_RIGHT_SECTION=(
  am_version_prompt
  am_vcs_prompt
)

Update left prompt asynchronously

export AM_ASYNC_L_PROMPT=1

Show initial new line

Always show a new line

export AM_INITIAL_LINE_FEED=1

Unset AM_INITIAL_LINE_FEED to stop printing a new line.

Add start tag and end tag:

export AM_PROMPT_START_TAG='-->'     # previously `PROMPT_START_TAG`     
export AM_PROMPT_END_TAG='\ $'       # previously `PROMPT_END_TAG`       
export AM_PROMPT_START_TAG_COLOR=81  # previously `PROMPT_START_TAG_COLOR`  
export AM_PROMPT_END_TAG_COLOR=81    # previously `PROMPT_END_TAG_COLOR`

Result:

--> ~ $
--> ~ $ 1
(venv) --> python-project $
(venv) --> python-project $ 130

You can additionally show the error color on prompt start tag:

export AM_ERROR_ON_START_TAG=1

Note: if AM_PROMPT_START_TAG is empty, this configuration will be ignored.

Show versions:

Available version are: PYTHON,PYTHON_S,RUBY,RUBY_S,JAVA,JAVA_S,GO,GO_S,ELIXIR,ELIXIR_S, CRYSTAL,CRYSTAL_S,NODE,NODE_S,PHP,PHP_S,GRADLE,MAVEN

export AM_VERSIONS_PROMPT=(RUBY PYTHON JAVA GO CRYSTAL NODE PHP ELIXIR GRADLE)

Customize Separator:

export AM_VERSION_PROMPT_SEP='|'

Note: Prompt maintain declaration order.

Configure dirname in prompt:

export AM_DIR_EXPANSION_LEVEL=2

The effect may be unnoticeable on faster CPUs.

Hide exit code:

export AM_HIDE_EXIT_CODE=1

Keep previous RPROMPT:

export AM_KEEP_PROMPT=1

Color themes:

1. export AM_THEME=mono
1. export AM_THEME=mono_bright
1. export AM_THEME=terminal
1. export AM_THEME=soft
1. export AM_THEME=default

Note: Unset AM_THEME to use default color scheme.

Apart from these default themes, custom colors can be defined:

Use previewer to easily preview colors.

export AM_VCS_COLOR=1          # color for VCS (G: M: V:)
export AM_SSH_COLOR=11         # color for ssh indicator
export AM_NORMAL_COLOR=12      # color for normal text
export AM_ERROR_COLOR=1        # color for ERROR
export AM_REV_COLOR=14         # color for VCS Revision number
export AM_BRANCH_COLOR=10      # color for VCS BRANCH name
export AM_LEFT_RIGHT_COLOR=3   # color for GIT Left-Right status
export AM_STASH_COLOR=3        # color for GIT stash count
export AM_BARE_COLOR=3         # color for GIT bare repo indicator
export AM_COMMIT_SINCE_COLOR=6 # color for last commit time
export AM_FADE_COLOR=8         # color for fade text color
export AM_VENV_COLOR=8         # color fir python virtual env text
export AM_PYTHON_COLOR=2       # color for python version text
export AM_RUBY_COLOR=1         # color for ruby version text
export AM_JAVA_COLOR=15        # color for java version text
export AM_TIMER_COLOR=14       # color for command execution time

Or creating a new theme file:

/path/to/custom/theme.zsh

#!/usr/bin/env zsh

am_theme(){
  AM_VCS_COLOR=248
  AM_SSH_COLOR=143
  AM_NORMAL_COLOR=39
  AM_ERROR_COLOR=208
  AM_REV_COLOR=248
  AM_BRANCH_COLOR=78
  AM_LEFT_RIGHT_COLOR=222
  AM_STASH_COLOR=222
  AM_BARE_COLOR=222
  AM_COMMIT_SINCE_COLOR=244
  AM_FADE_COLOR=242
  AM_VENV_COLOR=245
  AM_PYTHON_COLOR=40
  AM_RUBY_COLOR=196
  AM_JAVA_COLOR=178
  AM_GO_COLOR=81
  AM_ELIXIR_COLOR=81
  AM_CRYSTAL_COLOR=8
  AM_NODE_COLOR=2
  AM_PHP_COLOR=5
  AM_GRADLE_COLOR=2

  AM_TIMER_COLOR=248
  AM_PROMPT_START_TAG_COLOR=39
  AM_PROMPT_END_TAG_COLOR=39
  AM_GIT_TRACKED_COLOR=78
  AM_GIT_UN_TRACKED_COLOR=208
  AM_LEFT_RIGHT_COLOR=252
}

Then activate the theme using:

export AM_CUSTOM_THEME_PATH=/path/to/custom/theme.zsh

Nerd Font:

Nerd Font must be installed nerd-fonts

Enable Nerd Font

export AM_USE_NERD_FONT=1 # previously `USE_NERD_FONT`
