Session.vim: Cannot use :let in Vim 9 script

[trev-dev]

My vim seems to create a vim9script Session.vim where two little lets seem to throw when I re-start a session:

if filereadable(sx)
  exe "source " .. fnameescape(sx)
endif
&g:so = so_save | &g:siso = siso_save
nohlsearch
let g:this_session = v:this_session
let g:this_obsession = v:this_session
doautoall SessionLoadPost
unlet g:SessionLoad
# vim: set ft=vim :

The nuisance goes away and the session seems to otherwise keep working

Alright it looks like you may not see this until vim 9.2.84X

I have the same issue. Any comments how to fix it?

I put a comment in this PR: #87

If there isn't any traction in a little while I'll submit my own. In the meantime, I patched the plugin on my local machine. On

vim-obsession/plugin/obsession.vim

Line 78 in ed9dfc7

call insert(body, 'let g:this_session = v:this_session', -3)

you could do something like:

  if has('vim9script')
    call insert(body, 'g:this_session = v:this_session', -3)
    call insert(body, 'g:this_obsession = v:this_session', -3)
  else
    call insert(body, 'let g:this_session = v:this_session', -3)
    call insert(body, 'let g:this_obsession = v:this_session', -3)
  endif
