See my edit below, this is not totally a duplicate of Shell prompt customization and cmd behavior
My reverse-search function in the CLI is broken and I don't know how to fix it back...
When I hit ctrl+r and search a command I did earlier, find it then press the right arrow key to use it, the output is broken. Here is an example:
# I reverse-searched the word "test" then pressed right arrow
yoshiji@x1carbon:~/path/to/git/folder (master) $ch)`test': rake test
# ^^^^^^^^^^ weird output
# ^ cursor right there
It also "shifts" my cursor to a different position. If I press enter, the right command is executed (rake test in this case) so it means the text displayed is not the same as what is actually executed.
I know this is most-likely related to my PS1 export in my ~/.bashrc, so here are the last lines of this file:
# Git branch in prompt.
git_branch() {
branch=$(__git_ps1 2> /dev/null)
if [ "$branch" = " (master)" ]; then
echo -e "\033[33m${branch}\033[00m" # yellow
elif [ "$branch" = "" ]; then
echo -e "\033[90m (no git)\033[00m" # red
else
echo -e "\033[32m${branch}\033[00m" # green
fi
}
PS1='\u@\h:\w$(git_branch) \$ '
This is something I wrote to displays the git branch in orange (if master branch) or else in green (or no git in gray).
Do you guys have any idea on what is causing this weird behavior?
Edit: This is a different problem from the possible duplicate in the way that I am using echo -e "some string" to return a string having color+name of the git branch from the function git_branch(). Using echo -e does not escape the characters \[ and \] (try it yourself in your CLI: echo -e "\[\033[33m\]test").
Ideally, I would like to keep those conditional colors based on the branch's presence & name (gray if no branch, orange if master, else green).
