Regex to remove comment lines Topic is solved

[john_c]

Code: Select all

Test =
(
;       Foo
;Bar
;  aaa   aaaaa
Baz
)

Test := RegExReplace(Test, "???", "")
MsgBox % Test

Please, help me with regex. I need to remove any comment lines. I.e. only the Baz line should be kept.

"`am)^\s*;.*(?:\R|$)"

@Datapoint Thanks for your input, but the MsgBox is blank...

upd: Ah, after your edit it works. Thanks again.

If the comment line is the last one, the line break won't be removed by this way:

Code: Select all

Test =
(
;       Foo
;Bar
;  aaa   aaaaa
Baz
;  last comment
)

Test := RegExReplace(Test, "`am)^\s*;.*(?:\R|$)")
MsgBox % "|" Test "|"

Better like this:

Code: Select all

Test =
(
;       Foo
;Bar
;  aaa   aaaaa
Baz
;  last comment
)

Test := RegExReplace(Test, "m`a)(\R)?^\s*;.*(?(1)|\R)")
MsgBox % "|" Test "|"
