Basilisp support

Oh sounds pretty cool, I think I looked into this a long time ago. Has a Clojure-y feel to it with the data structures which I like.

A comment on Issue #628, pREPL Server in the Basilisp repo, says that there is some support for nREPL. See the section, Start an nREPL Session.

Just tried Basilisp with the Clojure client and it seems to work.

I started up a Basilisp nREPL server using basilisp nrepl-server.
After editing an empty test.lpy and manually setting the filetype to 'clojure', Conjure connected to the Basilisp nREPL server by reading the .nrepl-port file in the current directory.

I'm guessing that to get *.lpy files to automatically have Conjure connect the Clojure client to a Basilisp nRPEL server, one should configuring Neovim to associate *.lpy files to Clojure and set vim.g['conjure#filetype_suffixes#clojure'] to `{'cljc', 'clj', 'lpy'} .

See #609 which deals with Babashka files, *.bb for how to setup an autocommand for Neovim to associate *.lpy files with Clojure.

It doesn't appear that vim.g['conjure#filetype_suffixes#clojure'] needs to be set.

it works to me.

;; add clojure as filetype of basilisp
(vim.filetype.add {:extension {:lpy :clojure}})

;; add usercmd to start basilisp nrepl server
(vim.api.nvim_create_autocmd :FileType {:desc "[Basilisp] add `Basilisp` usercmd for starting Basilisp nrepl server"
                     :pattern :clojure
                     :callback #(vim.api.nvim_buf_create_user_command $.buf :Basilisp
                                             #(vim.cmd (.. "tabnew | term "
                                                           "basilisp nrepl-server"))
                                             {:nargs "*"})})

@lost22git, nice example of adding Basilisp as a Clojure filetype and adding a user command to start up a Basilisp nREPL server.

According to :he nvim_buf_create_user_command, that parameter is the buffer ID or 0 (zero) for the current buffer. I'm a bit confused by $.buf in the :callback portion of the autocommand creation. Could you help me out and explain how that works?

[lost22git]

buf is from args of callback

It would be better to read

;; add clojure as filetype of basilisp
(vim.filetype.add {:extension {:lpy :clojure}})

;; add usercmd to start basilisp nrepl server
(vim.api.nvim_create_autocmd :FileType {:desc "[Basilisp] add `Basilisp` usercmd for starting Basilisp nrepl server"
                     :pattern :clojure
                     :callback (fn [{:buf bufid}] 
  (vim.api.nvim_buf_create_user_command bufid :Basilisp
                                             #(vim.cmd (.. "tabnew | term "
                                                           "basilisp nrepl-server"))
                                             {:nargs "*"}))})

I've added a Quick-start page for people interested in using Conjure with Basilisp.
