批处理脚本:链接命令时出现彩色回声的问题 [英] Batch script : issue with colored echo when chaining commands

问题描述

在尝试使用批处理脚本以彩色显示某些文本时，我目前遇到问题.

I am currently facing an issue when trying to echo some text in color with a batch script.

仅当我尝试根据下一个命令的状态码在另一个命令(此处为git命令)后回显颜色时，才会发生我的问题:&&或||.

My issue only happens when I try to echo in color after another command (git command here) depending on the status code of the previous command : with && or ||.

示例:

@echo off
cls
for /F %%a in ('echo prompt $E ^| cmd') do set "ESC=%%a"

echo %ESC%[92mGreen%ESC%[0m
echo %ESC%[91mRed%ESC%[0m
echo %ESC%[92mGreen%ESC%[0m && echo %ESC%[91mRed%ESC%[0m
git pull || echo %ESC%[92mGreen%ESC%[0m && echo %ESC%[91mRed%ESC%[0m

pause

如您所见，在执行git pull命令后，彩色回显不再起作用.如果我使用&&代替||如果git pull返回成功.

As you can see, echo in color doesn't work anymore after my git pull command. This will be the same if I use && instead of || and if git pull returns success.

有什么主意吗?

谢谢.

推荐答案

只需调用标签，并在标签内引用颜色:

Just call labels and have the colors referenced inside the labels:

@echo off
cls
for /F %%a in ('echo prompt $E ^| cmd') do set "ESC=%%a"
call :green
call :red
git pull && call :green || call :red

goto :eof
:green
echo %ESC%[92mSuccess%ESC%[0m
goto :eof
:red
echo %ESC%[91mFailed%ESC%[0m
goto :eof

结果:

请注意条件运算符的顺序为:

Note the sequence of the conditional operators are:

command && errorlevel is 0 || errorlevel is larger than 0

换句话说，命令and如果成功，or如果不成功

in other words, command and if successful or if not successful
