Ignore file/directory (menu items)

[srbs]

Decided today to write up a simple ignore file & ignore directory menu item.

Both menu items are implemented using a git alias which also allows command line usage if wanted:

• ignore file: git smerge-ignore path/to/file
• ignore directory: git smerge-fetch path/to/file dir

Notes/Caveats:

• duplicate entries are skipped when identified
  • but no add/remove lines if the reverse logic is needed
• directories are always suffixed with /

Steps:

1. add this git alias:

   git config --global alias.smerge-ignore '!f() {
       local ignore_file="${1#"$PWD"}"
       local ignore_type="${2:-file}"
       
       local ignore_line
       case "$ignore_type" in
           dir*)
               ignore_line="$(dirname "$ignore_file")/"
               ;;
           *)
               ignore_line="$ignore_file"
               ;;
       esac
       
       if [ "" == "$(grep -Fx "$ignore_line" .gitignore)" ]; then
           echo "$ignore_line" >> .gitignore
           echo "added $ignore_type $ignore_file to .gitignore file"
       else
           echo "$ignore_type already exists, skipping"
       fi
   }; f'
   

2. add these menu items to File.sublime-menu:

   [
       {
           "caption": "Add file to .gitignore",
           "command": "git",
           "args": { "argv": ["smerge-ignore", "$path", "file"] }
       },
       {
           "caption": "Add this file's directory to .gitignore",
           "command": "git",
           "args": { "argv": ["smerge-ignore", "$path", "dir"] }
       }
   ]
