Caution
I've moved this gist over to a template repository here. Everything here is unmaintained...
Following are the extensions required for neovim:
I use lazy.nvim so, just add the following to your plugins table, or create a new file in lua/plugins/lsp.lua
return {
{
"williamboman/mason.nvim",
config = function()
require("mason").setup({})
end,
},
{
"williamboman/mason-lspconfig.nvim",
config = function()
require("mason-lspconfig").setup({
ensure_installed = { "lua_ls", "clangd" },
})
end,
},
{
"neovim/nvim-lspconfig",
config = function()
local lspconfig = require("lspconfig")
lspconfig.lua_ls.setup({})
lspconfig.clangd.setup({}) -- Minimal setup
end,
},
}For the LSP server setup (as recommended by @omani) this is what I use, it improves auto complete functionality
lspconfig.clangd.setup({
on_attach = on_attach,
capabilities = capabilities,
cmd = {
"clangd",
"--background-index",
"-j=12",
},
})I've made a script to do all this for you:
$ cd path/to/the/project
$ curl -sSL https://gist.github.com/ironlungx/a2b620de74f875c49c1d06999a8c41f8/raw/script.sh | sh
$ rm compile_commands.json
$ pio run -t compiledbBUT I DONT LIKE curl|sh:
-
Initialize a project with
pio init -
In the project root create the following files
-
.clangd: (thanks @omani for fixing and adding flags to the file)# clangd controls options for the LSP *server* CompileFlags: Add: [ -DSSIZE_MAX, -DLWIP_NO_UNISTD_H=1, -Dssize_t=long, -D_SSIZE_T_DECLARED, -Wno-unknown-warning-option ] Remove: [ -mlong-calls, -fno-tree-switch-conversion, -mtext-section-literals, -mlongcalls, -fstrict-volatile-bitfields, -free, -fipa-pta, -march=*, -mabi=*, -mcpu=* ] Diagnostics: Suppress: "pp_including_mainfile_in_preamble"
-
.clang-tidy: (thanks @omani for adding more flags!)Checks: '-*, -misc-definitions-in-headers' # Fixes some issue with header reinclusion IndentWidth: 2 # Only if you like 2, replace with 3/4/.. if you'd like
-
gen_compile_commands.py:import os Import("env") # platformio specific stuff # include toolchain paths (i.e. to have stuff like the Arduino framework headers present in the compile commands) env.Replace(COMPILATIONDB_INCLUDE_TOOLCHAIN=True) # override compilation DB path env.Replace(COMPILATIONDB_PATH="compile_commands.json")
-
-
Now add the following to your platformio.ini
extra_scripts = pre:gen_compile_commands.py -
Now in your terminal run:
pio run -t compiledb(Just delete the oldcompile_commands.jsonbefore executing this)
Hopefully this helped, I spent a lot of time figuring it out
hi @omani, thank you so much for the corrections (I didn't know there were syntax errors, unless you are talking about the script - it is very likely there are syntax errors there). I will put your changes into the main gist.
Thanks again
