[VSCode] some helpful bash additions

.bashrc

# if we have vscode installed...
if hash code 2>/dev/null; then
  # VSCode as default editor
  export EDITOR="code -w"

  # VSCode command line currently does not support piping from stdin
  # This helper function wraps the `code` command to capture piped stdin
  function code() {
    # reference to the original `code` command
    local code=$(which code)
    # if incoming stdin via a pipe...
    if [[ -p /dev/stdin ]] ; then
      local tmpFile=$(mktemp -t stdin)
      tee "$tmpFile" > /dev/null
      $code "$@" "$tmpFile"
    else
      # otherwise, pass along any arguments to the original `code`
      $code "$@"
    fi
  }
fi

This will...

• set code as your default $EDITOR
• wrap the code command so you can pipe stdin to it (e.g. git diff | code)
