Title: Set Selection: how-to use regex within "%d=" flag?
Post by: yescabernetnointernet on 14 December 2020, 19:38

Hay Roman, I cannot select all sets with word "japan" inside their description definition inside the DAT file...
Will you please help me?

Here's regex:

Code: [Select]

\b(japan)
Am I missing something?

That's the DAT: http://redump.org/datfile/dc/

OK, thanks.
Can you confirm I cannot use regexp inside one single declaration?
I mean the correct way would be, e.g.:

Code: [Select]

%d=foo;%d=boo;%d=moonot this way:

Code: [Select]

%d=\b(foo)|(boo)|(moo)
Just to clarify my thoughts

It's not a full regular expression implementation (hell, that code is 20 years old...)
You can use something like:

%d=[0-9][0-9] W*;%d=*(rev A)

to enable sets which start with "2 decimals space W" (e.g. 18 Wheeler)
The ; separates like an OR. So in the example you additionally select sets with a description ending "(rev A)".

Eh eh... ;D The long living clrmamepro!!!
BTW, OK thanks.
I also discovered that the Logical NOT switch, changes the behavior from the OR (standard) to AND. Right?

No, since it's not an NOT(A or B or C)...it's a NOT A or NOT B or NOT C
The not works on each sinlge part and actually this will usually end in something you don't expect.

not(sets starting with A); not(sets starting with B) -> this will still enable sets with A and B...... :-(
