Arch, Neovim nightly and jsregexp compilation

[resistorsoftware]

1. I installed Arch Lua51 headers and dev libraries
2. I did a make on the jsregexp library pointing at these libraries using
   make INCLUDE_DIR=-I/usr/include/lua51 LDLIBS=

This built me a jsregexp.so which I assume, is Lua51 compatible. I copy this to the ~/.config/nvim/lua directory so it can be found, and then I fire up Neovim, and issue the command to print(require("jsregexp")) but it still emits the error about undefined symbol: lua_newuserdatauv

I am this kind of stumped as to why the jsregexp module is not being picked up as correct for the LuaSnip? What else do I need to look for here?

Hi :)

Mhmm, maybe neovim finds some other, older .so.. what does :lua =vim.api.nvim_get_runtime_file("lua/jsregexp.so", true) print?

And, the current version of jsregexp additionally creates a jsregexp.lua-file which luasnip needs, have you dealt with that in any way?

Does make install_jsregexp work for you?

I fixed this by doing the following.

1. figured out the package.cpath and ensured any compiled jsregexp would be placed on the path
2. learned to compile the jsregexp with a custom makefile that took into account the installed nightly neovim, and its headers
3. copy the new jsregexp.so into the cpath and ensured no other jsregexp.so was available
4. added in the new function wrapper needed by new neovim to call and load the jsregexp

With all that, and it took quite a while to figure out (mostly the new makefile, building the jsregexp is not trivial!!) I had the correct behaviour inside neovim where the require("jsregexp") would return the expected table and no error!

All I know is, the process of getting Luasnip to work with jsregexp was a long one!
