Member Function Documentation

search_within_stream()

tools.misc_utils.ReSearch.search_within_stream (   input_stream,   pattern,   default = None  )

static

Search for regular expression in a file-like object.

Opens a file for reading and searches line by line for a match to
the regex and returns the parenthesized group named return for the
first match.  Does not search across newlines.

For example:
    pattern = '^root(:[^:]*){4}:(?P<return>[^:]*)'
    with open('/etc/passwd', 'r') as stream:
        return search_within_file(stream, pattern)
should return root's home directory (/root on my system).

Args:
    input_stream: file-like object to be read
    pattern: (string) to be passed to re.compile
    default: what to return if no match

Returns:
    A string or whatever default is
