Mac OSX | Bash .bash_profile不更新PS1

strnmn 发表于 Dev

力量

我有一个名为.bash_prompt的小脚本，source ~/.bash_prompt在〜/ .bash_profile中被调用。

该脚本将我的PS1设置为显示有关当前git repo的一些有用信息。不幸的是，只有在生成新终端时才执行git-part，因此仅当我更改为git repo后手动调用脚本时才显示该分支。

每次执行命令时，如何使bash提示更新？

function git_branch() {
    local GITDIR=$(git rev-parse --show-toplevel 2>&1)
    if [[ "$GITDIR" != '/Users/\u' ]]
    then
        local BRANCH=`git branch 2> /dev/null | sed -n '/^\*/s/^\* //p'`
      if [ -n "$BRANCH" ]; then
          echo -e "$BRANCH"
      fi
    else
     echo ""
    fi
}

function git_prompt() {
    local prompt_unpushed_symbol="△"
    local prompt_unpulled_symbol="▽"
    local prompt_dirty_symbol="*"
    local prompt_synced_symbol="✓"

    local local_branch=$(git_branch)
    local remote_branch="origin/$local_branch"
    local first_log="$(git log $local_branch $remote_branch -1 2> /dev/null)"

    local STATUS=`git status 2>&1`
    if [[ "$STATUS" == *'Not a git repository'* ]]; then
        echo ""
    elif [[ "$STATUS" != *'working directory clean'* ]]; then
        echo "[$local_branch $prompt_dirty_symbol]"
    elif [[ "$STATUS" == *'Your branch is ahead'* ]]; then
        echo "[$local_branch $prompt_unpushed_symbol]"
    elif [[ -n "$first_log" ]]; then
        echo "[$local_branch $prompt_unpulled_symbol]"
    else
        echo "[$local_branch $prompt_synced_symbol]"
    fi
}

function colorPrompt {
    local c_brace="\[\033[m\]"
    local c_git="\[\033[31m\]"

    local user_host="\[\033[36m\]\u\[\033[m\]@\[\033[32m\]\h"
    local location="\[\033[33;1m\]\w"
    local tail="\n\$ "

    export PS1="[$user_host $location$c_brace]$c_git$(git_prompt)$c_brace$tail"
}
