rustup-version-name

Show the used Rust toolchain version name for the current working directory.

If you use rustup you may have toolchain overrides for certain directories. Sometimes it is good to see which one that is. Put it in your prompt and it is there when you need to know.

Install

cargo install --git https://github.com/badboy/rustup-version-name

Use

rustup-version-name

Add the following function to your .bashrc or .zshrc:

__rust_prompt() {
  local rustp=$(rustup-version-name)
  if [ -n "$rustp"  ] && [ "$rustp" != "default"  ]
  then
    echo " $rustp"
  fi
}

Add the function to your PS1:

PS1="[%~\$(__rust_prompt)%# "

Restart your shell and your done.
