[BUG] Error If postwindow float in not enable

gilfuser commented 1 year ago

Hi there!

After reinstalling scnvim (by mistake) I can't start scnvim anymore. I ran :checkhealth scnvim and there's nothing wrong there.

If I have in the config file

...
    postwin = {
        float = {
            enabled = false,
        },
    },
...

...which I prefer, and I do :SCNVimStart in a .scd file, sclang won't start and I'll get this:

Error executing Lua callback: ...vim/site/pack/packer/start/scnvim/lua/scnvim/postwin.lua:134: Vim(mkview):E32: No file name

@gilfuser Hi, thanks for the report!

Error executing Lua callback: ...vim/site/pack/packer/start/scnvim/lua/scnvim/postwin.lua:134: Vim(mkview):E32: No file name

The error suggests that the (post window) buffer does not have a name, are you perhaps using some kind of vim session handler plugin that tries to restore previously opened windows/buffers?

gilfuser commented 1 year ago

Ah... yes I am. I had this piece of code here to make vim remember folds between sessions:

augroup remember_folds
      autocmd!
      autocmd BufWinLeave * mkview
      autocmd BufWinEnter * silent! loadview
augroup END

changing to that solved the problem:

augroup remember_folds
    autocmd!
    autocmd BufWinLeave ?* mkview | filetype detect
    autocmd BufWinEnter ?* silent loadview | filetype detect
augroup END

thank you David!

best regards
