" autoload/vimwiki/vars.vim — compatibility shim for plugins that depend on
" the original vimwiki API (e.g. vimwiki-sync, vim-zettel).
"
" Only the subset of `vimwiki#vars#get_wikilocal` keys that third-party
" plugins are known to call is implemented here; add entries as needed.
" Values are read from nuwiki's own config variables so users don't have
" to duplicate settings.

" Per-wiki local config values.
"
" Supported keys:
"   path            — wiki root directory (with trailing slash)
"   is_temporary_wiki — always 0 for a configured wiki
"   ext / extension — file extension (default '.wiki')
"   syntax          — syntax name (default 'vimwiki')
