New submission from Gregory Anders <[email protected]>:
Currently pydoc returns an exit code of zero no matter what, even with e.g.
pydoc lsjdfkdfj
However, the ability to know whether or not pydoc successfully found a result
is useful in tools that embed pydoc in some way.
Here's one use case: Vim and Neovim have a feature that allows a user to run an
external command for the keyword under the cursor (keywordprg). In Python
files, this defaults to pydoc. In Neovim, we would like to automatically close
the PTY buffers that we create for these processes when they finish without any
errors, but if it returns a non-zero exit code we want to keep the PTY buffer
open so the user can see what went wrong. Because pydoc returns immediately
when it fails to find a match and does not indicate that it failed via a return
code, the PTY buffer is closed immediately with no indication to the user that
anything went wrong.
I have a patch prepared for this that I will link to the issue.
