Regex to remove comment lines

01 Jul 2019, 10:38

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.

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 "|"
