#70072: neovim 0.10.0: missing tree-sitter parsers
-------------------------+--------------------
 Reporter:  thestr4ng3r  |      Owner:  (none)
     Type:  defect       |     Status:  new
 Priority:  Normal       |  Milestone:
Component:  ports        |    Version:  2.9.3
 Keywords:               |       Port:  neovim
-------------------------+--------------------
 As of 0.10.0, neovim assumes a couple of bundled tree-sitter parsers to be
 installed in the prefix under `/lib/nvim/parser`:
 {{{
 $ ls (...)/lib/nvim/parser/
 bash.so                 lua.so                  markdown_inline.so
 query.so                vimdoc.so
 c.so                    markdown.so             python.so
 vim.so
 }}}

 This is currently not the case with the port and thus neovim reports
 errors like these when opening e.g. `:help`:
 {{{

 Upstream instructions about the parsers is here:
 https://github.com/neovim/neovim/blob/master/BUILD.md#how-to-build-
 without-bundled-dependencies
 > If treesitter parsers are not bundled, they need to be available in a
 parser/ runtime directory (e.g. /usr/share/nvim/runtime/parser/).

 As suggested there, the parsers can be built and made to be installed
 during the actual neovim build by running something like the following
 before the configure phase, in order to only bundle the tree-sitter
 parsers but no other dependencies:
 {{{
 cmake -S cmake.deps -B .deps -G "Unix Makefiles" -D
 CMAKE_BUILD_TYPE=Release -DUSE_BUNDLED=OFF -DUSE_BUNDLED_TS_PARSERS=ON
 cmake --build .deps
 # now build neovim itself
 }}}
