--- Deno's built-in language server
---
--- To appropriately highlight codefences returned from denols, you will need to augment vim.g.markdown_fenced languages
--- in your init.lua. Example:
---
--- ```lua
--- vim.g.markdown_fenced_languages = {
--- "ts=typescript"
--- }
--- ```
local lsp = vim.lsp
local function virtual_text_document_handler(uri, res, client)
if not res then
return nil
end
local lines = vim.split(res.result, '\n')
local bufnr = vim.uri_to_bufnr(uri)
local current_buf = vim.api.nvim_buf_get_lines(bufnr, 0, -1, false)
if #current_buf ~= 0 then
return nil
end
vim.api.nvim_buf_set_lines(bufnr, 0, -1, false, lines)
vim.api.nvim_set_option_value('readonly', true, { buf = bufnr })
vim.api.nvim_set_option_value('modified', false, { buf = bufnr })
vim.api.nvim_set_option_value('modifiable', false, { buf = bufnr })
lsp.buf_attach_client(bufnr, client.id)
end
local function virtual_text_document(uri, client)
local params = {
textDocument = {
uri = uri,
},
}
local result = client:request_sync('deno/virtualTextDocument', params)
virtual_text_document_handler(uri, result, client)
end
local function denols_handler(err, result, ctx, config)
if not result or vim.tbl_isempty(result) then
return nil
end
local client = vim.lsp.get_client_by_id(ctx.client_id)
for _, res in pairs(result) do
local uri = res.uri or res.targetUri
if uri:match '^deno:' then
