Over the last few years I have converted from Perl and Scheme to
Python. There one task that I do often that is really slick in Perl
but escapes me in Python. I read in a text line from a file and check
it against several regular expressions and do something once I find a match.
For example, in perl ...
if ($line =~ /struct {/) {
do something
} elsif ($line =~ /typedef struct {/) {
do something else
} elsif ($line =~ /something else/) {
} ...
I am having difficulty doing this cleanly in python. Can anyone help?
rx1 = re.compile(r'struct {')
rx2 = re.compile(r'typedef struct {')
rx3 = re.compile(r'something else')
m = rx1.match(line)
if m:
do something
else:
m = rx2.match(line)
if m:
do something
else:
m = rx3.match(line)
if m:
do something
else:
error
(In Scheme I was able to do this cleanly with macros.)
