Vim9 autoload case regression

[Christian J. Robinson]

If I run the attached caseregression.sh file I get the following errors:

% bash caseregression.sh
Error detected while processing /home/infynity/.vim/plugin/CaseRegression.vim[3]../home/infynity/.vim/autoload/CaseRegression.vim:
line    2:

I was wondering if the fix in 8.2.4069 was too simple.
Looks like we should only ignore case if file names are not case
sensitive.

Thanks, that problem is fixed now. However, I can't access CaseRegression#CaseRegression() outside of the plugin/CaseRegression.vim file. Is this intentional? If so, is there a way around it?

Oops, it looks like it's only inaccessible under Windows. It seems to be fine under Linux.

If I remove the "import autoload 'CaseRegression.vim'" and instead use:

echo CaseRegression#CaseRegression()

That works for me. At least on Linux.

Can you show what does not work for you?

With the "import autoload 'CaseRegression.vim'" you can use "echo CaseRegression#CaseRegression()" on Linux, but on Windows it has to be "echo caseregression#CaseRegression()". This inconsistency is the problem I'm facing.

Is that at the script level or in a :def function? Or both?

You can try changing get_autoload_prefix() to always use vim_strsave()
instead of strlow_save() on windows. But I wonder what else will fail
then.

I'm using the # form in mappings because the .
form is unavailable at that point.

Right now I'm just working around it on Windows by creating a reference to the proper case.

if !has('fname_case')
g:CaseRegression#CaseRegression = CaseRegression CaseRegression
endif

I've changed my get_autoload_prefix() to always use vim_strsave() and I haven't noticed any issues yet.

OK, let's go that way. The big advantage is that scripts work both on
MS-Windows and Linux that same way, one should always use the case of
the file name. On MS-Windows two files that only differ in case are the
same file, let me add a test for that.
