Sublime Text selection using Lua/love2d - lua

Question

say i have this line of code :
Object.Property.field;
Object.Property:FunctionName();
in all my sublime languages if i was to double click "Property" on either line, it would select just that word.
For some reason my lua/lua love2d syntax highlighting selects the whole line up to the ":"
How can I change this behavior, so it will only select the single word?

Answer 1

The reason this is occurring is because of a somewhat strange addition to the Lua Love plugin, which I assume you're using. You're using Sublime 2, so select Preferences -> Browse Packages... to open up your Packages folder, then open the Lua Love subfolder. There is a file called completions.py, which has this content:
#completions.py
import sublime
import sublime_plugin
import re
class LoveCompletions(sublime_plugin.EventListener):
ST = 3000 if sublime.version() == '' else int(sublime.version())
def on_query_completions(self, view, prefix, locations):
if self.ST < 3000 and ("lua" in view.scope_name(locations[0])):
seps = view.settings().get("word_separators")
seps = seps.replace('.', '')
view.settings().set("word_separators", seps)
Even if you don't know Python, the logic is pretty easy to follow. It sets the variable ST to Sublime's version, which is 3000+ if you're using ST3 (current build is 3061), and is 2221 (I think) for ST2. It then sets up an event listener (the process is always running in the background) checking to see if the Sublime version is less than 3000 (you're using ST2) and you have lua in your current scope (basically, your file is source.lua or source.lua.love, if you're using the plugin's language definition). If both of those are true, it removes the . character from your "word_separators" setting, which is defined in Preferences -> Settings-Default and can be overridden in Preferences -> Settings-User.
The word_separators setting controls what characters are considered to be word separators when double-clicking to select a word. Its default value is ./\\()\"'-:,.;<>~!##$%^&*|+=[]{}`~? so, for example, if you double-click on the foo part of foo-bar Sublime will only select foo, but if you double-click on the foo part of foo_bar Sublime will select the whole thing (since - is in word_separators). . is in word_separators by default, so double-clicking on foo in foo.bar will only select foo, which is expected behavior for most people, I would assume. However, this cute little plugin removes . from word_separators in Sublime Text 2, so in your case clicking on Property selects everything from the beginning of the "word" (the whitespace before Object) to the next word separator - the :, in the case of your second example.
OK, so we know what the problem is, how do we fix it? First, while you're in Packages/Lua Love, just delete completions.py altogether. There's no harm in doing so, and in fact it's actually causing harm by being there. Make sure you restart Sublime after deleting the file. Next, open Preferences -> Settings-User and add . back into the word_separators list, anywhere between the beginning and ending double-quotes. Save that file, go back to your source code, and double-clicking should once again behave normally.
Good luck!
EDIT
I submitted this pull request to delete the completions.py file from the plugin's Github repo, and it was just merged, so hopefully users in the future won't have to deal with this :)
