PS1换行与颜色问题

Question

这是我的PS1变量:

PS1='\u:\W$(__git_ps1 "\e[32m\][%s]\e[0m\]")$ '

非常适合拾取我的Git分支,但它在颜色处于活动状态时包裹线条会产生令人遗憾的副作用,因此当您使用长命令时它们会重叠.

任何拥有魔法PS1技能的人都可以帮我解决这个问题吗？

Answer 1

知道了,需要正确地逃避颜色.

固定:

PS1='\u:\W$(__git_ps1 "\[\e[32m\][%s]\[\e[0m\]")$ '

Answer 2

我可以为Bash中的颜色建议以下方法,它使代码更具可读性,并且您很难错过一两个转义.

将以下内容放在〜/ .bashrc中

BLACK=$(tput setaf 0)
RED=$(tput setaf 1)
GREEN=$(tput setaf 2)
LIME_YELLOW=$(tput setaf 190)
YELLOW=$(tput setaf 3)
POWDER_BLUE=$(tput setaf 153)
BLUE=$(tput setaf 4)
MAGENTA=$(tput setaf 5)
CYAN=$(tput setaf 6)
WHITE=$(tput setaf 7)
BRIGHT=$(tput bold)
NORMAL=$(tput sgr0)
BLINK=$(tput blink)
REVERSE=$(tput smso)
UNDERLINE=$(tput smul)

样本PS1(或实际打印到屏幕上的任何内容)将是:

 PS1="\[${WHITE}\](\[${YELLOW}\]\u@\h\[${WHITE}\])\[${NORMAL}\]$ "

你只需要在颜色词周围加上\ [\].

如果你有一个256色的终端,你可以尝试其他数值来'tput setaf'一直到255.

Answer 3

这些是我经常使用的颜色函数...几年前就编写了它们，并且已经习惯了它们，因此它们是我脚本编写的常规部分。只需将此代码块粘贴到您的.bashrc文件中，开始一个新的会话，就可以设置好了！

我将它们用作彩色/时尚的printf替代品：

唯一要记住的是，当需要%百分号或\反斜杠时，需要在内部将它们加倍：
like： printf "$(Tblue "%%s")\n" 'hi'
但不是for Tblue "%s\n" 'hi'
或printf "$(Tblue "%s" 'hi')\n"

由于这些使用printf，因此您可以执行以下操作：

 printf "hi $(Tred there) man $(BaquaI "%c" '!') $(Bold 'This \\t is %%s') %s\n" "$(BgreenB 'super')" "$(Bblue mega Colorful)"

或回声中：

 echo "hi $(Tred there) man $(BaquaI "%c" '!') $(Bold 'This \\t is %s' "$(BblackB 'super')") $(Bblue mega Colorful)"

一个更有用的示例：

printf "\t%s Volume \"%s\" is not connected.\n" "$(TwhiteB [)$(TredB Error)$(TwhiteB \]:)" "$(Tbrown $Volume)"

或与其他命令：

eval "echo 'This is OSX' | sed 's:OSX:$(Invert [)$(TaquaF OSX)$(Invert ]):'"

或有些更扑朔迷离的东西：

find . -exec stat -f "Name: $(Tbrown %%N)%t%t$(Tpurple "->")%tPermissions: $(Tgreen %%Sp)" {} \;

动用你的想象力！随意使用这些...我唯一要问的是是否有人在那里键入更多，混合/匹配它们（例如TcyanBgreenUI或自己命名）...可以请给我发布它们，以及让我知道这个帖子吗？或通过aesth1r@me.com将它们发送给我。我懒得输入所有可能性。

请享用！
