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.

Compatibility

Tested with Sublime Text 2 build 2095 and later. The key bindings described below will work for build 2134 (and onwards, presumably).

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 },
    { "key": "panel_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 },
    { "key": "panel_visible", "operator": "equal", "operand": false }
  ]
},

To map to the tab key it gets a bit more complex to preserve indentation behaviour:

{ "keys": ["tab"], "command": "alternative_autocomplete", "args": {"default": "\t"}, "context":
  [
    { "key": "num_selections", "operator": "equal", "operand": 1 },
  ]
},
{ "keys": ["shift+tab"], "command": "alternative_autocomplete", "args": {"cycle": "previous"}, "context":
  [
    { "key": "num_selections", "operator": "equal", "operand": 1 },
  ]
},
{ "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.
