Matching pattern with words and apostrophes

I'm splitting strings into individual words to create an auto-completion dictionary, but my current code does not account for words with apostrophes in them.
I'd like the dictionary to store combinations such as "doesn't", "let's", etc.

I'm currently using the pattern "[%a][%w]+", which is perfectly fine for coherent words, but will cut words with apostrophes into parts.

"[%a][%w']*[%w]+" should match a word containing an apostrophe.

Thanks! Works like a charm! Kudos on the quick response, too.

Question

Going to keep using this thread for pattern questions.

How can I remove texture sequences from a string?

How do I turn this:
Lua Code:
  1. HELP_OPTIONS_MOVED = "|TInterface\\OptionsFrame\\UI-OptionsFrame-NewFeatureIcon:0:0:0:-1|t  Colorblind and Move Pad options have been moved to the Accessibility section.";
  2. NPE_MAPCALLOUTBASE = "|TInterface\\WorldMap\\WorldMapArrow:28:28|t marks your location.\n\n";

...into this:
Lua Code:
  1. HELP_OPTIONS_MOVED = "  Colorblind and Move Pad options have been moved to the Accessibility section.";
  2. NPE_MAPCALLOUTBASE = " marks your location.\n\n";

There might be a better funciton, but this also works:

Lua Code:
  1. local substring = string.gsub("|TInterface\\OptionsFrame\\UI-OptionsFrame-NewFeatureIcon:0:0:0:-1|t  Colorblind and Move Pad options have been moved to the Accessibility section.", "|T.*|t", "")
  2. print(substring)

  2. print(string)
That simple? Thanks.

"|T.-|t" would be better, if you use .* and you have more than one texture in the string it will match everything from the first texture to the last texture and remove the text in between.

Thanks semlar. There should be an extensive resource on pattern matching somewhere. I find the official documentation very confusing, with inconclusive examples. Or, you know, maybe I'm just dumb as hell.

http://wow.gamepedia.com/Pattern_matching is a good resource for lua and http://regular-expressions.info/tutorial.html for learning regex in general.

http://wiki.roblox.com/index.php/String_Formatting is the best Lua pattern resource I've found.

That's for string.format rather than the pattern matching functions, did you mean to link this page?
