Lines of Code in Eclipse PyDev Projects

I'm wondering if anyone开发者_高级运维 has had any luck using the Eclipse Metrics Plugin with Projects that are not in Java (specifically I'm trying to generate code metrics for a couple of PyDev Projects). I've read through the walk-through for the Metrics project but it indicates that I should be in the Java Perspective before accessing the Properties for my Project and that I should find a Metrics section. I don't get that for my PyDev Projects regardless of which Perspective I have open. Any suggestions or advice would be great.

I don't know if it's doable to get the plugin to work with pydev projects, but if it's just the lines-of-code metric you are after, you could run this snippet in your project's root directory:

# prints recursive count of lines of python source code from current directory
# includes an ignore_list. also prints total sloc

import os
cur_path = os.getcwd()
ignore_set = set(["__init__.py", "count_sourcelines.py"])

loclist = []

for pydir, _, pyfiles in os.walk(cur_path):
    for pyfile in pyfiles:
        if pyfile.endswith(".py") and pyfile not in ignore_set:
            totalpath = os.path.join(pydir, pyfile)
            loclist.append( ( len(open(totalpath, "r").read().splitlines()),
                               totalpath.split(cur_path)[1]) )

for linenumbercount, filename in loclist: 
    print "%05d lines in %s" % (linenumbercount, filename)

print "\nTotal: %s lines (%s)" %(sum([x[0] for x in loclist]), cur_path)

If you are in Linux...

Have you taken a look to cloc?

It produces pretty complete outputs, and accepts several of options:

borrajax@borrajax-linux:~/Documents/Projects/myProject$ cloc .
    1840 text files.
    1566 unique files.                                          
    9362 files ignored.

It is available in the Ubuntu repositories, as well.

On Unix you can run the following from the terminal:

find . -name '*.py' | xargs cat | egrep "[a-zA-Z0-9_{}]" | wc -l

If you want to not count comments, you need a better regular expression...
