Hi,
I am trying to write a program that scans the GTK headers. I am getting
confused about the following regular expression, and was hoping someone
could help explain...
Here is some simplified code that illustrates my problem. I am trying to
match a prototype and extract the return type... the problem is I am
matching against the second one, when I don't think my regex says that...
str = 'char * gtksomething'
str2 = 'extern "C" { } gtksomething'
regex = re.compile(r'([\w\s*]*?)gtk')
m = regex.search( str )
print m.group(0)
print m.group(1)
m = regex.search( str2 )
print m.group(0)
print m.group(1)
On my system that second one matchs... ? Output is:
char * gtk
char *
extern "C" { } gtk
extern "C" { }
How the heck is the [\w\s*] class matching the chars { } and "
