Bash function to edit scripts faster

I am often editing my own scripts as I develop them. I want to make a better workflow for working with scripts like this.

Currently
─────────

Currently I am combining nvim with a which subshell to etit these files like this.

│ for now lets use my todo command as an example

[code]
  nvim `which todo`

First pass
──────────

On first pass I made a bash function to do exactly what I have been doing.

[code]
  ewhich () {$EDITOR `which "$1"`}

The $1 will pass the first input to the which subshell. Now we can edit our todo script like this.

[code]
  ewich todo

│ Note, I use bash functions instead of aliases for things that require input.

Final State
───────────

This works fine for commands that are files, but not aliases or shell functions. Next I jumped to looking at the output of command -V $1.

- if the command is not found, search for a file
- if its a builtin, exit
- if its an alias, open my

  ~/.alias file to that line
- if its a function, open my

  ~/.alias file to that line

[code]
  ewhich () {
  case `command -V $1` in
      "$1 not found")
          FILE=`fzf --prompt "$1 not found searching ..." --query $1`
          [ -z "$FILE" ] && echo "closing" || $EDITOR $FILE;;
      *"is a shell builtin"*)
          echo "$1 is a builtin";;
      *"is an alias"*)
          $EDITOR ~/.alias +/alias\ $1;;
      *"is a shell function"*)
          $EDITOR ~/.alias +/^$1;;
      *)
          $EDITOR `which "$1"`;;
  esac

a bit more ergo, and less readable
──────────────────────────────────

To make it easier to type, at the sacrifice of readability for anyone watching I added a single character e alias to ewhich. So when I want to edit anything I just use e.

[code]
  alias e=ewhich

Here is a quick screencast of how it works.
