It probably does the job, but -honestly- I've never even used 'gfind'
before.
string.gfind is really handy.
As an example, the question of iterating over a string which was
floating around earlier could probably best be handled with:
for ch in string.gfind(str, ".") do
-- handle a character
end
. The point is, Lua should be intuitive and straightforward, and "for
line in string.lines(str)" was the first thing I'd try just by
guessing.
So put this in your startup:
function string.lines(str) return string.gfind(str, "[^\n]+") end
:)
Some time ago I put some other string-slinging examples, several taken
from PIL, on the wiki: http://lua-users.org/wiki/StringRecipes
