Adding custom queries

[ranjithshegde]

Discussed in #233

Since setting conceal from treesitter has been merged in core, I have been trying to set my own queries for org bullets like this

(
((stars) @stars (#eq? @stars "*")) @_conceal
(#set! conceal "◉")
)
(
((stars) @stars (#eq? @stars "**")) @_conceal
(#set! conceal "○")
)
(
((stars) @stars (#eq? @stars "***")) @_conceal
(#set! conceal "✸")
)
(
((stars) @stars (#eq? @stars "****")) @_conceal
(#set! conceal "✿")
)

When I append the above snippet to packer/*/orgmode/queries/org/highlights.scm it works perfectly. However when I do it in my ~/.config/nvim/after/queries/org/highlights.scm it does not apply.

according to @kristijanhusak's checking, disabling todo-keyfaces highlight solves this as a workaround for now

I think the issue is here. According to the treesitter docs (here), the set_query() function will override the defaults, so any user query files in /after/queries/highlights.scm are ignored after running filetype detect.

The solution might be to iterate over all query_files and gather the user-set queries then call vim.treesitter.set_query() and filetype detect at the end.

Yes set_query() is the problem.
However, custom queries do work with other filetypes as most parsers are handled by nvim-treesitter directly. I have a variety of conceals and textobjects written for markdown and supercollider that are not overridden.

EDIT: Not directly related to this issue but relevant. My PR to detect orgmode natively in vim was merged. And the vim-patch for neovim is also merged

@ranjithshegde can you check if it works now?

[ranjithshegde]

I somehow missed the merge notification. Yes it works!!
Thanks @kristijanhusak and @gerritvreeman for your wonderful work
