StringRegExpRelace / Selective match

[HurleyShanabarger]

I am currently trying to do some code refactoring using regular expressions.

If boThis Then // Remove this
    boThat := TRUE; // Keep this
    boThere := boSome OR // Remove this
               boThing;  // Remove this
EndIf

Basically I want to remove comments, whenever the assignment operator := and the colon is not in the line.

$_lv_sData = ''
$_lv_sData &= 'If boThis Then // Remove this' & @CRLF
$_lv_sData &= ' boThat := TRUE; // Keep this' & @CRLF
$_lv_sData &= '    boThere := boSome OR // Remove this' & @CRLF
$_lv_sData &= '               boThing;  // Remove this' & @CRLF
$_lv_sData &= 'EndIf' & @CRLF
$_lv_sRslt = StringRegExpReplace($_lv_sData, "(?m)^([^;]+)(//.*)$", "$1", 0)
MsgBox(0,"", $_lv_sRslt)

How do I add the assignment operator := into the regular expression?

Thanks a lot!

Ca you try this one ?

$_lv_sRslt = StringRegExpReplace($_lv_sData, "(?m)^(?:.+:=[^;]+\K\/\/\V+|[^:]+\K\/\/\V+)", "")

So... just skip this line

$_lv_sRslt = StringRegExpReplace($_lv_sData, "(?m)^.+:=.+;.*(*SKIP)(*F)|//\V+", "")

Holy moly, a whole new world just appeared for me 😄

Yep    suggested reading : this

Please note that in this case \K could be used instead of (*SKIP)(*FAIL)
