Hello,
I'm trying to analyze some autolisp code with python. In the file to
be analyzed there are many functions. Each function begins with a
"defun" statement. And before that, there may or may not have comment
line(s), which begins with ";". My goal is to export each function
into separate files, with comments, if there is any. Below is the code
that I'm struggling with:
[code]
path = "C:\\AutoCAD\\LSP\\Sub.lsp"
string = file(path, 'r').read()
import re
pat = "\\;+.+\\n\\(DEFUN"
p = re.compile(pat,re.I)
iterator = p.finditer(string)
spans = [match.span() for match in iterator]
for i in range(min(15, len(spans))):
print string[spans[i][0]:spans[i][1]]
[/code]
The code above runs fine. But it only takes care of the situation in
which there is exactly one comment line above the "defun" statement.
How do I repeat the sub-pattern "\\;+.+\\n" here?
For example if I want to repeat this pattern 0 to 10 times, I know
"\\;+.+\\n{0:10}\\(DEFUN" does not work. But don't know where to put
"{0:10}". As a work around, I tried to use
pat = "|".join(["\\;+.+\\n"*i+ "\\(DEFUN" for i in range(11)]), and it
turned out to be very slow. Any help?
Thank you.
Kelie
