I wrote a small plugin, which tries to do what vim-obsession does as well as some functionalities of vim-prosession (basically just restoring the last session automatically when Vim starts).
But it has an issue which I think vim-prosession also has. When my plugin restores automatically the session, if the latter contains a help buffer (and 'sessionoptions' contains help), its settings are not restored. Including the syntax highlighting.
I tried a workaround, invoking a function s:restore_help_settings_when_needed(), at the end of the restoration process. It iterates over the buffers and when it detects one whose path matches a help buffer, it sets the right options. For some reason, the settings don't survive if I reload the help buffer, so the function also installs an autocmd listening to BufRead:
call s:restore_help_settings_when_needed()
fu! s:restore_help_settings_when_needed() abort
let cur_bufnr = bufnr('%')
sil! bufdo if expand('%') =~# '/doc/.*\.txt$'
\| call s:restore_help_settings()
\| endif
if bufexists(cur_bufnr)
exe 'b '.cur_bufnr
endif
endfu
fu! s:restore_help_settings() abort
setl ft=help nobuflisted noma ro
so $VIMRUNTIME/syntax/help.vim
augroup restore_help_settings
au! * <buffer>
au BufRead <buffer> setl ft=help nobuflisted noma ro
augroup END
endfu
It works, but there's still an issue. If I try to jump to the definition of a tag defined in a help buffer which was restored by the plugin, again, there's no syntax highlighting in the new help buffer.
I don't know how the :help command works, but it seems that it reads the help buffers in a special way. So, I thought that the only way to restore a help buffer, was to use :help. Maybe using a code like this:
The first command would invoke :help on the current help buffer. The 2nd one would jump back to where the cursor was. It works but not immediately, I have to manually reload the buffer (and IIRC it opens another window, displaying the same buffer, so a window needs to be closed).
All in all, I haven't been able to find a way to restore a help buffer without some manual intervention.
I tried vim-obsession + vim-prosession and they seem to have the same issue.
By any chance, do you know why this happens, and how to solve it?

Thank you very much for your plugin.
