" development/tests/test-vimwiki-compat-vim.vim — upstream-vimwiki config
" drop-in compatibility for the Vim client.

" Sourced by test-vimwiki-compat-vim.sh under headless Vim. Sets an upstream
" `g:vimwiki_list` + `g:vimwiki_*` config and asserts nuwiki#lsp#settings()
" translates it into the server's schema. Writes PASS/FAIL to
" $NUWIKI_VWC_OUT; the wrapper fails on any FAIL.
