在目录中搜索多行字符串

Question

Looking for a way to recursively search a repository for all files containing a multi line string and return the file names that contain it. The paragraph is just a header approx 30 lines.

Below is the approach I am taking but is not working.

repo = os.getcwd()

header = """ /*
             /* .......paragraph
             /* ..............
             */
         """

for file in glob.glob(repo):
    with open(file) as f:
        contents = f.read()
    if header in contents:
        print file

I am getting this error:

IOError: [Errno 21] Is a directory: '/home/test/python/repos/projects/one'

Edited new version @zondo

def findAllFiles(directory):
    gen = os.walk(directory)
    next(gen)
    return [os.path.join(path, f) for path, _, files in gen for f in files]

def main():
    print "Searching directory for copyright header"
    for file in findAllFiles(repo):
        with open(file) as f:
            contents = f.read()
    if header in contents:
        print file

Answer 1

With the os module, you can do this:

# Find not only all files in a folder, but all files in all sub-directories
def find_all_files(folder):
    return [os.path.join(path, f) for path, _, files in os.walk(folder) for f in files]

for file in find_all_files(repo):
    with open(file) as f:
        contents = f.read()
        if header in contents:
            print file

Try using subprocess and pcregrep for matching multiple lines in different directories.

from subprocess import call
call(["pcregrep", "-rM","<regular_exp>","<path to directory>"])

Never tried this. Just came to my mind
