git - 使用 'vcs_info' 根据状态着色 git 分支名称

Question

我是 zsh 的新手(我是很长一段时间的 bash 用户)我有一个自定义提示(由不同的来源混合而成)，其中有一个特定的 git 部分。:

我想要: - 如果 git status 显示“clean”，则 (master) 为绿色 - 如果 git status 说“不干净”

， (master) 为红色

我不知道我该怎么做，如果有人知道，我将不胜感激。

我的.zshrc:

# (...)
# Easy colors in ZSH scripting
autoload -U colors && colors

setopt prompt_subst
autoload -Uz vcs_info

function +vi-git-untracked() {
  if [[ $(git rev-parse --is-inside-work-tree 2> /dev/null) == 'true' ]] && \
  [[ $(git ls-files --other --directory --exclude-standard | sed q | wc -l | tr -d ' ') == 1 ]] ; then
  hook_com[unstaged]+='%F{red}??%f'
fi
}

# Show remote ref name and number of commits ahead-of or behind
function +vi-git-st() {
  local ahead behind remote
  local -a gitstatus

  # Are we on a remote-tracking branch?
  remote=${$(git rev-parse --verify ${hook_com[branch]}@{upstream} \
    --symbolic-full-name 2>/dev/null)/refs\/remotes\/}

  if [[ -n ${remote} ]] ; then
    ahead=$(git rev-list ${hook_com[branch]}@{upstream}..HEAD 2>/dev/null | wc -l)
    (( $ahead )) && gitstatus+=( "${c3}+${ahead}${c2}" )

    behind=$(git rev-list HEAD..${hook_com[branch]}@{upstream} 2>/dev/null | wc -l)
    (( $behind )) && gitstatus+=( "${c4}-${behind}${c2}" )

    hook_com[branch]="${hook_com[branch]}${(j:/:)gitstatus}"
  fi
}

# Show count of stashed changes
function +vi-git-stash() {
  local -a stashes

  if [[ -s ${hook_com[base]}/.git/refs/stash ]] ; then
    stashes=$(git stash list 2>/dev/null | wc -l)
    hook_com[misc]+="%f (%F{1}STASH=${stashes}%f)"
  fi
}

我的回答将基于我的个人喜好和zsh-users 中关于如何使用vcs_info 的示例目录。

我建议您采用 vcs_info-examples 中第三集 中解释的方法你可以找到文件 here .

precmd() {
    # As always first run the system so everything is setup correctly.
    vcs_info
    # And then just set PS1, RPS1 and whatever you want to. This $PS1
    # is (as with the other examples above too) just an example of a very
    # basic single-line prompt. See "man zshmisc" for details on how to
    # make this less readable. :-)
    if [[ -n ${vcs_info_msg_0_} ]]; then
        # Oh hey, nothing from vcs_info, so we got more space.
        # Let's print a longer part of $PWD...
        PS1="%5~%# "
    else
        # vcs_info found something, that needs space. So a shorter $PWD
        # makes sense.
        PS1="%3~${vcs_info_msg_0_}%# "
    fi
}

从那开始(以及您提供的代码片段)我会这样做:

precmd() {
    vcs_info
    if [[ -n ${vcs_info_msg_0_} ]]; then
        # vcs_info found something (the documentation got that backwards
        # STATUS line taken from https://github.com/robbyrussell/oh-my-zsh/blob/master/lib/git.zsh
        STATUS=$(command git status --porcelain 2> /dev/null | tail -n1)
        if [[ -n $STATUS ]]; then
            PROMPT='%F{green}%n%F{orange}@%F{yellow}%m:%F{7}%3~%f %F{red}${vcs_info_msg_0_} %f%# '
        else
            PROMPT='%F{green}%n%F{orange}@%F{yellow}%m:%F{7}%3~%f %F{green}${vcs_info_msg_0_} %f%# '
        fi
    else
        # nothing from vcs_info
        PROMPT='%F{green}%n%F{orange}@%F{yellow}%m:%F{7}%3~%f %# '
    fi
}

一些注意事项:

• 第一个if示例文件中的错误
• STATUS定义取自 oh-my-zsh
• 您可以更改 zstyle如果STATUS反而脏了
• 您可以提高 git status 的性能通过使用像 --untracked-files[=<mode>] --ignore-submodules[=<when>] 这样的标志来部分对于 git-status

希望对你有帮助
