Alternative autocompletion for Sublime Text 2

This plugin adds an autocompletion command to Sublime Text 2 that acts similarly to TextMate:

• Hitting the autocomplete key will attempt to complete the current word by looking at similar words in the current document.

• Hitting the autocomplete key multiple times will cycle through the available words.

• The last autocomplete position is remembered, so you can perform an autocompletion, move the cursor around, move back to where you were, and continue cycling through the completions.

• Candidate completions are selected prioritized by distance to the cursor.

The plugin improves on TextMate in one respect: If no candidates are found, the plugin reverts to using a simple fuzzy, case-insensitive matching algorithm that is similar to Sublime's file/class matching algorithm. For example, typing appc might match ApplicationController.

Tested with Sublime Text 2 build 2095.

Installation

Drop the entire folder in Sublime's Packages folder. You can do this using git clone thus:

$ cd .../Packages  # Whatever the location is
$ git clone git://github.com/alexstaubo/sublime_text_alternative_autocompletion.git

To map to the escape key, like TextMate:

{ "keys": ["escape"], "command": "alternative_autocomplete", "context":
  [
    { "key": "num_selections", "operator": "equal", "operand": 1 },
    { "key": "overlay_visible", "operator": "equal", "operand": false }
  ]
},
{ "keys": ["shift+escape"], "command": "alternative_autocomplete", "args": {"cycle": "previous"}, "context":
  [
    { "key": "num_selections", "operator": "equal", "operand": 1 },
    { "key": "overlay_visible", "operator": "equal", "operand": false }
  ]
},

To map to the tab key:

{ "keys": ["tab"], "command": "alternative_autocomplete", "args": {"default": "\t"}, "context":
  [
    { "key": "num_selections", "operator": "equal", "operand": 1 },
    { "key": "overlay_visible", "operator": "equal", "operand": false }
  ]
},
{ "keys": ["shift+tab"], "command": "alternative_autocomplete", "args": {"cycle": "previous"}, "context":
  [
    { "key": "num_selections", "operator": "equal", "operand": 1 },
    { "key": "overlay_visible", "operator": "equal", "operand": false }
  ]
},
{ "keys": ["tab"], "command": "indent", "context":
  [
    { "key": "text", "operator": "regex_contains", "operand": "\n" }
  ]
},
{ "keys": ["shift+tab"], "command": "unindent", "context":
  [
    { "key": "text", "operator": "regex_contains", "operand": "\n" }
  ]
},

Limitations

Currently does not work with multiple selections.
