Filters documentation?
« on: March 12, 2015, 09:30:18 PM »
I've come across some info here:

https://github.com/mickelson/attract/wiki/Example-filters

Is there any other resource for filter information?  I'd like to build some but more info out there would be great.  I generally just slash my way through code, bastardize it and then criticize it :)

Cools had a couple examples as well:

Is there something you don't understand, or just wanting more examples?

Thanks Liquid for the link!

This is luckily one of the items that I'm actually looking to figure out vs. chasing something I've misconfigured!  Documentation / organized chaos like this, perhaps?

https://www.autoitscript.com/autoit3/docs/functions.htm

Luckily it doesn't look like filtering is as complex as hacking apart Autoit code!

Filters are simply doing pattern matching using the squirrel library's regular expressions (bugs and all).  So the squirrel documentation, particularly this: http://www.squirrel-lang.org/doc/sqstdlib3.html#d0e2183 will be of some help too.

^   Match the beginning of the string

[]   Character class

GREEDY CLOSURES.

*   Match 0 or more times
+   Match 1 or more times
?   Match 1 or 0 times
{n}   Match exactly n times

{n,m}   Match at least n but not more than m times
ESCAPE CHARACTERS.

\t   tab (HT, TAB)
\n   newline (LF, NL)
\r   return (CR)
\f   form feed (FF)

PREDEFINED CLASSES.
