窗户的Git bash提示符不是从一个函数显示颜色 [英] Windows Git bash prompt not displaying colours from a function

问题描述

我用下面的颜色codeS /功能（保罗爱尔兰捏）在我.bash_prompt，显示在Windows的Git的bash支行名称和状态。

I'm using the following colour codes/function (pinched from Paul Irish) in my .bash_prompt, to display branch name and status in Git bash on windows.

MAGENTA="\033[1;31m"
ORANGE="\033[1;33m"
GREEN="\033[1;32m"
PURPLE="\033[1;35m"
WHITE="\033[1;37m"
BOLD=""
RESET="\033[m"

function git_info() {

        # check if we're in a git repo
        git rev-parse --is-inside-work-tree &>/dev/null || return

        # quickest check for what branch we're on
        branch=$(git symbolic-ref -q HEAD | sed -e 's|^refs/heads/||')

        # check if it's dirty (via github.com/sindresorhus/pure)
        dirty=$(git diff --quiet --ignore-submodules HEAD &>/dev/null; [ $? -eq 1 ]&& echo -e "*")

        echo $WHITE" on "$PURPLE$branch$dirty
}

该功能显示的信息正确，但而不是着色两部分它打印出来的颜色codeS这样的：

The function displays the information properly, but instead of colouring the two parts it prints out the colour codes like this:

\[\033[1;37m\] on \[\033[1;35m\]working*
$

这是利用以下的（减少来说明这个问题）PS1行：

This is using the following (reduced to illustrate the problem) PS1 line:

PS1="\$(git_info)\n$ "

我要指出，如果codeS直接添加到PS1线即颜色做工精细：

I should note that colours work fine if the codes are added directly to the PS1 line i.e:

PS1="\[$PURPLE\]\w\n$ \[$RESET\]"

我感觉在我的路这一切庆典定制的，所以可能会做一些明显的愚蠢！

I'm feeling my way around all this bash customisation, so might be doing something obviously stupid!

推荐答案

也许回声-e 。从人回声：

-e使反斜杠间pretation逃逸

此外，您还可以使用双引号里面的变量：

Also, you can use variables inside double quotes:

echo "$WHITE on $PURPLE$branch$dirty"
