错误PS1 GIT功能 - Gitbash与Cygwin之间的冲突

我正在收到以下错误，试图自定义我的PS1以获取GIT

错误：

bash: command substitution: line 1: syntax error near unexpected token `)'
bash: command substitution: line 1: `get_dir)'
bash: command substitution: line 1: syntax error near unexpected token `)'
bash: command substitution: line 1: `get_branch)'
bash: command substitution: line 1: syntax error near unexpected token `)'
bash: command substitution: line 1: `parse_git_dirty)'

我的.bashrc

#...
function get_dir() {
    [[ ${PWD} == $HOME ]] && echo '~' || echo ${PWD##*/}
}
function get_branch() {
    [[ -d .git ]] && echo "$(git branch --show-current)" 
}
#...

这很棘手！这首先要在我的Cygwin上完美工作，但是当我使用此语法“修复”时，在Gitbash上产生了这个错误

export PS1="${LIGHTGREEN}\t${NC} ${PINK}\$(get_dir)${NC}${LIGHTBLUE} \$(get_branch) ${NC}${RED}\$(parse_git_dirty)${NC} \n${GREEN}$ ${NC}"

，我没有错误，但没有动态工作。每次更改目录，

export PS1="${LIGHTGREEN}\t${NC} ${PINK}`get_dir`${NC}${LIGHTBLUE} `get_branch` ${NC}${RED}`parse_git_dirty`${NC} \n${GREEN}$ ${NC}"

即更改\ $（get_dir） get_dir

在Cygwin上导致：

原文

I'm receiving the following error trying to customize my PS1 for git

Error:

bash: command substitution: line 1: syntax error near unexpected token `)'
bash: command substitution: line 1: `get_dir)'
bash: command substitution: line 1: syntax error near unexpected token `)'
bash: command substitution: line 1: `get_branch)'
bash: command substitution: line 1: syntax error near unexpected token `)'
bash: command substitution: line 1: `parse_git_dirty)'

My .bashrc

#...
function get_dir() {
    [[ ${PWD} == $HOME ]] && echo '~' || echo ${PWD##*/}
}
function get_branch() {
    [[ -d .git ]] && echo "$(git branch --show-current)" 
}
#...

Here's tricky! this first snipped worked perfectly on my Cygwin, but produce that error on Gitbash

export PS1="${LIGHTGREEN}\t${NC} ${PINK}\$(get_dir)${NC}${LIGHTBLUE} \$(get_branch) ${NC}${RED}\$(parse_git_dirty)${NC} \n${GREEN}$ ${NC}"

when I "fix it" using this syntax, I've got no error but it's NOT working dynamically. I Need to reload my .bashrc each time that I change the directory

export PS1="${LIGHTGREEN}\t${NC} ${PINK}`get_dir`${NC}${LIGHTBLUE} `get_branch` ${NC}${RED}`parse_git_dirty`${NC} \n${GREEN}$ ${NC}"

i.e. changed \$(get_dir) to get_dir

Result on Cygwin:

在尝试“修复”它时，您可以在导出ps1 IS 执行时执行get_dir。

相反，每次生成新提示时，您都需要对其进行重新评估。也许最简单的方法是定义函数my_prompt，该>在调用时，计算PS1字符串，然后设置

export PS1='$(my_prompt)'

此功能，还可以使您在在提示符中激活函数之前调试函数。

In your attempt to "fix" it, you execute get_dir by the time the export PS1 is executed.

Instead, you need to have it reevaluated every time a new prompt is generated. The perhaps simplest way to do it is to define a function my_prompt which, when called, calculates the PS1 string, and then set
