custom PS1 template powerline

[oscarenzo]

Hello,

I would like to know how can to customize the variable PS1 that by default show my prompt:

platano  ❲p❳ ansible29  /usr/local/bin 

It is:

{user}{python virtualenv}{pwd}

The problem in this case is when you are in directory very nested the prompt can be very large:

earroyo  ❲p❳ ansible29  /usr/local/bin/for/bar/for/bar/path with name large/bar/for/bar/for/bar/ 
How can I edit for the pwd not show complete, maybe just the last directory name or the two or three directories, where can I edit?, what is the var that get these values?

I'm using the theme 'poweline'

Thank you

It is defined in the following place:

oh-my-bash/themes/powerline/powerline.base.sh

Lines 92 to 94 in 1272a39

	function __powerline_cwd_prompt {
	echo "$(pwd | sed "s|^${HOME}|~|")|${CWD_THEME_PROMPT_COLOR}"
	}

Instead of directly editing the powerline theme file, you can define your own "segment" in .bashrc such as

# Your segment named "mycmd":
function __powerline_mycwd_prompt {
  echo "\w|${CWD_THEME_PROMPT_COLOR}"
}
POWERLINE_PROMPT="user_info scm python_venv ruby mycwd"

When you use the prompt escape sequence \w, you can control the number of directories shown by setting PROMPT_DIRTRIM. Note that this variable needs to be specified after source "$OSH/oh-my-bash.sh" because it overwrites the variable.

Have you added this setting?

function __powerline_mycwd_prompt {
  echo "\w|${CWD_THEME_PROMPT_COLOR}"
}
POWERLINE_PROMPT="user_info scm python_venv ruby mycwd"

If it still does not work with the above setting, what would be shown when you run the following command?

$ echo "$POWERLINE_PROMPT"

@akinomyoga thank you very much, I'm deleted my first comment by it was wrong, I forget the function, now it works, this is the result:

earroyo  ❲p❳ ansible29  ../bar/for/bar/ 

Thank you very much again!, doubt solved :)

NOTE: Finally my config look like this:

source "$OSH"/oh-my-bash.sh

# OHMyBash custom segment it called "mycustomcwd":
function __powerline_mycustomcwd_prompt {
  echo "\w|${CWD_THEME_PROMPT_COLOR}"
}
POWERLINE_PROMPT="user_info scm python_venv ruby mycustomcwd"

PROMPT_DIRTRIM=2
