Hi all,
the docstring for pcomplete-ignore-case (which is now an alias for
completion-ignore-case) says:
Non-nil means don’t consider case significant in completion.
For file-name completion, ‘read-file-name-completion-ignore-case’
controls the behavior, rather than this variable.
But if I set read-file-name-completion-ignore-case to t I'm still unable
to complete, for example, "cd ~/desk<tab>" to "cd ~/Desktop" in a
shell. OTOH setting pcomplete-ignore-case to t gives the desired
completion.
I'm not sure whether something like "cd ~/desk<tab>" in a M-x shell
counts as "file-name completion" or not, but it seems to me that it
should.
Best regards,
Carlos

Just to clarify -- read-file-name-completion-ignore-case works
everywhere else, but doesn't work in a *shell* buffer?

C-x C-f ~/desk<tab> --> ~/Desktop
M-x shell<enter> cd ~/desk<tab> --> no completion
M-x shell<enter> cd ~/Desk<tab> --> ~/Desktop
This is with default settings:
read-file-name-completion-ignore-case t
completion/pcomplete-ignore-case nil

I think that's a "yes". 😀
Following the call sequence here is quite complicated. The following
fixes the issue, but is it the correct solution here?

Hi Lars,
Thanks! Your fix works for me. I'm not sure if this is the best place to set
completion-ignore-case though. If you look at the code for
comint--complete-file-name-data you will find that
completion-ignore-case is set in the same way that you did. But perhaps
too late because at that point comint-completion-file-name-table has
already been called. Perhaps the best fix is to bind completion-ignore-case
earlier in comint--complete-file-name-data. But if
comint-completion-file-name-table is intended to be called from other places,
then it's better to set completion-ignore-case there as you did.
Best regards,
Carlos

Yeah, me neither. The completion machinery is hard to grok -- there's
so many magical wrappers and stuff that reasoning about it is a challenge.

Yes, I think so.

I think I tried doing that, and it didn't do the right thing, but I may
be mistaken.

I bet Stefan has some insights here; added to the CCs.
