如何修改conda'源激活'ps1行为 [英] how to modify conda 'source activate' ps1 behavior

问题描述

我当前的bash ps1如下:

my current bash ps1 is as follows:

bldred='\e[1;31m' # Red
bldcyn='\e[1;36m' # Cyan
bldwht='\e[1;37m' # White
txtrst='\e[0m'    # Text Reset - Useful for avoiding color bleed

export PS1="\n\[$bldred\]\u\[$txtrst\]@\[$bldwht\]\h\[$txtrst\]:\[$bldcyn\]\w\[$txtrst\]$ "

但是，正在运行:

source activate <env-name-here>

默认情况下，告诉conda将env-name放在我的PS1之前:

by default, tells conda to prepend the env-name to my PS1:

(<env-name-here>)
user@short-domain:fullpath$

是否有办法告诉conda将env-name插入我的PS1中，特别是在换行符之后?

Is there a way to tell conda to insert the env-name within my PS1 instead, specifically, right after the newline?

推荐答案

我找到的最简单的解决方案是将换行符从PS1移到PROMPT_COMMAND:

The simplest solution I have found is to move the newline from PS1 to PROMPT_COMMAND:

bldred='\e[1;31m' # Red
bldcyn='\e[1;36m' # Cyan
bldwht='\e[1;37m' # White
txtrst='\e[0m'    # Text Reset - Useful for avoiding color bleed

PROMPT_COMMAND="printf '\n'"
export PS1="\[$bldred\]\u\[$txtrst\]@\[$bldwht\]\h\[$txtrst\]:\[$bldcyn\]\w\[$txtrst\]$ "

这允许conda保持其默认的PS1行为，同时用换行符分隔bash命令:

This allows conda to maintain it's default PS1 behavior all while separating bash commands with newlines:

user@short-domain:fullpath$ source activate <env-name-here>

(<env-name-here>) user@short-domain:fullpath$
