AttributeError: 'NoneType' object has no attribute 'group'

[mpolidori]

I'm getting an AttributeError with certain commands (rm -r and mkdir -m for example). Same error with the py.test commands. I found that If I remove env={"MANWIDTH": "80"}, the error disappears.

python manly.py mkdir -m
Traceback (most recent call last):
  File "manly.py", line 191, in <module>
    main()
  File "manly.py", line 180, in main
    title, output = manly(args.command)
  File "manly.py", line 151, in manly
    re.search(r"(?<=^NAME\n\s{5}).+", manpage, re.MULTILINE).group(0).strip()
AttributeError: 'NoneType' object has no attribute 'group'

So far I have tested this on 2 laptops. Unfortunately, they're both Arch Linux, so I haven't had a chance to test another distro yet.

I'm not sure if there's any other information I should provide. I don't know where to begin troubleshooting because I don't fully understand all of the changes in the new version yet.

If it's an Arch specific issue, this can probably be closed, and I'll attempt to find a workaround so I can update my AUR package fork to 0.4.0 (which is currently working with version 0.3.4). I can just remove env={"MANWIDTH": "80"}, but I agree that setting it to 80 greatly improves readability, especially in large or full screen terminals.

Sorry about that, I've set it up to pass the full environment again so the issue should be resolved in the current master branch!

[mpolidori]

It's resolved. Thanks!

for the sake of building testcases to avoid this in the future, if you have the time available, could you post the outputs of env -i man mkdir > manly_envless_rm and env > manly_env ? (after redacting any sensitive information from the two files, of course!)

[mpolidori]

When I run env -i man mkdir > manly_envless_rm, I receive this error:

man: nroff: Bad system call (core dumped)
man: command exited with status 159: (cd /usr/share/man && /usr/lib/man-db/zsoelim) | (cd /usr/share/man && /usr/lib/man-db/manconv -f UTF-8:ISO-8859-1 -t ANSI_X3.4-1968//IGNORE) | (cd /usr/share/man && tbl) | (cd /usr/share/man && nroff -mandoc -rLL=84n -rLT=84n -Tascii)

And nothing is in the resulting file. I tested commands other than mkdir with the same result on both of my laptops. Again, they're both using the same distro, so I'm not sure if it's specific to that.

I searched a bit and read that the error could be an issue with groff files. I tried:

pacman -Qk groff
groff: 603 total files, 0 missing files

All looks good. I'm not sure where to go from there, but I'll keep searching.

With env > manly_env, this is the result:

I don't believe any of the above info is sensitive information, but correct me if I'm wrong.

Hello! Thanks for cool and manly utility!
Unfortunately, I get the same error on ArchLinux.

I tried installing it both via pipx and yay - the result is the same. I see that this issue is resolved but what is the fix to problem?

P.S. Sorry for reviving old issue, haven't noticed that it was created 5 years ago - created separate issue.
