Filter with Regex

[Lagi Pittas]

Hi

I have an ini file and wanted to make it easy to change the ON/OFF settings easily so I read it in and then
filter the lines to remove lines with comments emopty lines and non ON/OFF settings so that if the file is

Code: Select all

OPENONPAID=ON
CREDITCARD=ON
MIXDEFAULT=OFF
IMAGE=OPEN.png
SLIDESHOW=i1.png,o2.png
PRINTER=pOFFICE

I can filter to get

Code: Select all

OPENONPAID=ON
CREDITCARD=ON
MIXDEFAULT=OFF

Now I can get it to work outside of livecode using PRE regex using

Code: Select all

.*=(ON).*|(OFF).*

Im sure livecode doesn't allow the brackets so the closes i can get is

Code: Select all

 "*=O[NF]*"

This patches what I need but it also matches Printer=OFFICE so I have to put an extra letter in front of an "OFFICE" printer.


Is there a cheat sheet of what is acceptable in Livecode or at least how alternation works or will I have to find all Thierry's posts and save them for posterity (or is that Humanity)

Hi Lagi,

You could try this one:

Code: Select all

   filter myIni with regex pattern "=(ON|OFF)$"

and if you would like to accept extra spaces or tabs in a line,
do that:

Code: Select all

   filter myIni with regex pattern "=\s*(ON|OFF)\s*$"

Thanks Thierry

I thought the brackets weren't accepted in LC - maybe it was other stuff in my code ... , but this will help immensely for future regexes.

Thanks again

Your a star
