Using Sublime Text and Auto Fold with PICO 8 files

Auto Fold is a Sublime Text package that can be used to automatically code fold the header and tail data of your *.p8 files to get them out of your way while working on your code. To do this:

1. Use Package Control (assuming you've installed Package Control) to search for and install Auto Fold.
2. Use the "Package Control:List Packages" command to open a list of your installed packages.
3. Click on the Auto Fold package to open File Explorer to the package location.
4. Open Auto Fold.sublime-package as if it were a ZIP archive (it is) with something like 7-Zip. (Or, follow the package instructions to find the following file on GitHub.)
5. Copy the AutoFold.sublime-settings file from the archive to the Packages\User folder in this same part of the tree. (For me this is: C:\Users\xxxx\AppData\Roaming\Sublime Text 3\Packages\User)
6. Edit and save that settings file to contain the lines I've added for PICO-8 (lines 16, 17, and 26 -- and don't forget to add commas to lines 15 and 25) as seen here:

{
  "attributes" : [ // attributes to auto-fold
    "href",
    "src"
  ],

  "tags": [ // tags auto-fold
    "h1"
  ],

  // "\\{(.|\n)*?\\}" // note: multiline regexps should include \n.
  // "." does not mach new lines
  "regexps": [ // regexps to auto-fold
    "(?<=(url)\\().*?(?=\\))", // fold urls in css files
    "(?<=\\()http.*?(?=\\))", // fold markdown urls "(http://..)"
    "^pico(.*\n)*__lua__$", // PICO-8 header
    "^__gfx__(.*\n)*" // PICO-8 data block
  ],

  "extensions": [  // activate this plugin for file extensions:
    "html",
    "htm",
    "css",
    "xml",
    "md",
    "p8"
  ],

  "runOnLoad": true, // auto-fold on load
  "runOnSave": true // auto-fold on save
}
