Hi, I've got a half working re but I can't find a way to give it the
final touch.
Let's say I have (it would actually be source code file) :
import re
MyString = """Algo
... Start
... otro
... comment
... otro
... comment
... comment
... otro
... end
... """
MyPattern =
re.compile(r'(.*?Start.*?)((comment.*?)*)(comment)(.*?end)', re.S)
print MyString
Algo
Start
otro
comment
otro
comment
comment
otro
end
print MyPattern.sub(r'\1\2/*\4*/\5', MyString)
Algo
Start
otro
comment
otro
comment
/*comment*/
otro
end
Which is basically ok. I have to find the last "comment" in the block
and comment it. But I'd like to comment the whole line, my desired
output would be :
Algo
Start
otro
comment
otro
comment
/* comment*/
otro
end
And if there was something after the "comment" I would also like it to
be commented :
from:
comment and something else
to :
/* comment and something else*/
any help?
A quick attempt that works for your example:
MyPattern =
re.compile(r'(.*?Start.*?)((\n\s*comment.*?)*\n)(\s*comment.*?)(\n.*?end)',
re.S)
You might look into something like pyparsing instead of a complicated re.
