Hi,

I found this issue when I tried grep_iter

StopIteration Traceback (most recent call last)
~\Anaconda3\lib\site-packages\grepfunc\grepfunc.py in grep_iter(target, pattern, **kwargs)
234 # done iteration
--> 235 raise StopIteration
236

StopIteration:

The above exception was the direct cause of the following exception:

RuntimeError Traceback (most recent call last)
in
6
7 # print all people with first name 'Bob'
----> 8 for POT in grep_iter(infile, "WPOT_TOTAL2"):
9 print (POT)

RuntimeError: generator raised StopIteration

It might need to end loop when the codes read the end of the line?

Read the Grep on File section:

The following example will return a list of movie names without the word 'dog' in them, read from a file.

Yet, the actual code is as below:

from grepfunc import grep

the file contains the following list of words: ['Ghost Dog', 'Die Hard', 'Matrix', 'The Ring', 'Cats and Dogs', 'Batman', 'Superman', 'Reservoir Dogs']

infile = open('movies.txt', 'r')

grep titles without the word 'dog' in them from file. Note: i=True will ignore case.

grep(infile, "dog", i=True)

output:

>>> ['Ghost Dog', 'Cats and Dogs', 'Reservoir Dogs']

Note two things:

1. The v=True option is not included in this code, so there is no inversion of the logic, and we are looking for 'dog'
2. The output includes all of the entries with the word dog in them, even though the text comment says that we are working to grep the titles without the word 'dog' in them. This is very confusing, and wrong... the output is correct for the code given, but the descriptions are wrong.

While this seems trivial, this puts the average user who is simply trying to grep through a file with python into a confusing quest to understand why the results are backwards.

Two fixes needed: Both the high level description and the comment in the code need to say that we are looking for the movie names WITH the word Dog in them.

Hello. I was looking for something similar to grep and came across to your project.

Unfortunately, it doesnt seem to work with Python 3.

When I tried

from grepfunc import grep

I got:

In [56]: from grepfunc import grep
---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)

---> 10 from grepfunc import (grep, grep_iter)
     11

ImportError: cannot import name 'grep'

I have had this error:

File ".\wpy64\python-3.8.5.amd64\lib\sre_parse.py", line 668, in _parse
# raise source.error("nothing to repeat",

error: nothing to repeat

Any idea?
