Folds forgotten after beginning debug session about vdebug HOT 12 CLOSED

Interesting... does this happen if you create a new tab in Vim, open a few buffers then close the tab and return to the file with the manual folds? This is essentially all that Vdebug should be doing, so it might be that it's something that Vim does. Unless there's some weird side effect going on!

Only happens with Vdebug as far as I can tell.

OK, intriguing. Will investigate.

Hi there,

Finally been able to give this some time, but I can't reproduce it: folds are remembered for me. Can you give me an example of the steps you're using, with vim commands?

Thanks

• Open a vim file with folds, or :set fdm=manual and make some
• zM: close all folds
• zo on a fold: open it
• <F10>: set a breakpoint
• <F5>: start debugging

The fold(s) should be reset/destroyed by this point. Best tried with manual folds for full effect.

Edit: Also, it is not necessary to set a breakpoint. Simply starting the debugger will do it.

Hi Quinn,

I've managed to reproduce this with setting foldmethod to marker and setting a manual fold. It appears that reloading the file in vim (e.g. with :e) clears manual folds defined in that file, and that's what Vdebug is doing - it loads every file that Xdebug (or whichever engine) tells it to, and if you've defined manual folds then they get cleared as a result of Vim's normal behaviour.

Do you know if there's any "soft" loading that Vim can do? I.e. load the file only if there isn't already a buffer, otherwise show that buffer?

Thanks

function s:edit(filename)
    try 
        execute 'buffer' fnameescape(a:filename)
    catch /^Vim\%((\a\+)\)\=:E94/ 
        execute 'edit' fnameescape(a:filename)
    endtry
endfunction

Should do the trick.

Edit: added fnameescape() for good measure (unsure if your filenames will already be escaped)

Nice, thanks for that. I'll give it a whirl when I can.

Hey Quinn,

I added your function (slightly modified) and managed to get some manual folds remembered. Seems to work pretty well, but if you could give the updated dev branch a go you're probably best placed to test it.

Cheers

@qstrahl have you given this a go?

Thanks

Sorry, completely forgot about this! I'd love to close the issue, but currently can't confirm due to #84

from vdebug.

Confirmed fixed as of cb9ebd3
