I just noticed the type sig of goto definition allows for multiple definition returns

Use cases, if we have a method name without a type we should return a list of all methods with that name

If we has a definition/declaration split or multiple potential definitions we should also return all of those

https://github.com/dapetcu21/atom-autocomplete-lua

we can complete simple expressions, like

module.a.b:c()

but only when we know the type of each of the ids. We should be equally informative in these kinds of cases:

local a = { str = return_a_string() }
a.str:m---

or the inline equivalent, like for example

("string"):m
return_a_table().a
assert(module.table).a

These are all built around guessing what the type of a Call or Invoke expression will be and then storing it.

I tried installing following the instructions:
$ luarocks install --from=http://luarocks.org/dev lua-lsp

but i received an error:
Error: No results matching query were found.

it only found the download with:
$ luarocks install --from=http://luarocks.org/dev lua-lsp

completion/goto definition works pretty okay when you're pointing it at a plain expression/lhs. it doesn't understand the following examples, though:

-- in comments
"in strings"
{ at_table_lhs = {}}

these suffer from the "changing scope" problem that regular scopes do.

lua-fmt is, at the moment, the most powerful and consistent formatter for Lua.

It works with multiple Lua versions, is well tested and is the only one so far that handles things like lines that are too long due to function calls - breaking arguments into multiple lines.

It has places that could be improved but the creator and maintainer, Trinx, is really open to contributions and feedback.

Not very familiar with Lua, so I don't know how to find much more info than this. It seems to start happening if I start using a variable without declaring it.

Interestingly, according to the line number, the assertion that's failing is assert(pos <= document.text:len()).

However, this error goes away if I restart the server, even without changing any code.

Let me know if (and how?) to get any extra info!

I am having this issue on Ubuntu 16.04.

When I run this:
./luarocks install --server=http://luarocks.org/dev lua-lsp
I get:
Error: Failed finding Lua header files. You may need to install them or configure LUA_INCDIR.

At that point of time, Lua has already been installed, and LUA_INCDIR env var has been set to Lua's src directory which contains the headers.

Any idea?

experimenting with lua-lsp, got weird assertion failures when mousing over the name of a function with ... arguments:

/usr/local/share/lua/5.1/lua-lsp/methods.lua:175: assertion failed! stack traceback: [C]: in function 'assert' /usr/local/share/lua/5.1/lua-lsp/methods.lua:175: in function 'make_items' /usr/local/share/lua/5.1/lua-lsp/methods.lua:650: in function '?' /usr/local/share/lua/5.1/lua-lsp/loop.lua:55: in function </usr/local/share/lua/5.1/lua-lsp/loop.lua:54> [C]: in function 'xpcall' /usr/local/share/lua/5.1/lua-lsp/loop.lua:54: in function 'main' ...r/local/lib/luarocks/rocks/lua-lsp/scm-2/bin/lua-lsp:3: in main chunk [C]: ?

Haven't got a fix, might try to make one if you're interested and I get free time.

local module = { my_constant_field = "woah" }

function module:method()
    return self.my_
end

should autocomplete as imagined. This is not strictly true that self will always be module, but the intent is to make the common case helpful instead of correctly represent the language semantics. Hopefully we can also support simple setmetatable usage, too.

Native modules can't be easily parsed the way lua can: for one we might not even have the source. So it makes sense to provide a .luacompleterc-inspired format that can either be hand-made or generated, and then can be loaded when a user tries to use this kind of a module. imagined filesystem structure

hi,

Thanks for the nice package. Would be nice to accept more recent lpeglabel to prevent this:

-- Performing Test HAS_DIAG_COLOR_FLAG - Success
-- Found PkgConfig: /nix/store/50vxsm7w48l5mqa2f114c43vcyyixxn0-pkg-config-0.29.2/bin/pkg-config (found version "0.29.2")
Missing dependencies for lua-lsp scm-2:
   lpeglabel ~> 1.5 (1.6.0-1 installed)

lua-lsp scm-2 depends on lpeglabel ~> 1.5 (1.6.0-1 installed)

Also I package this program for nixos and it would be cool to have:

• a rock available as well on luarocks.org
• fill the rockspec description instead of "No summary";

if we find a global by parsing a file, we should probably assume that every other file has access to that global. this means the global table exists on a workspace level, not a document level

Here is the error output:

I use Homebrew installed Lua 5.3

• macOS version: Big Sur
• Lua version: 5.3, 5.4 (installed with Homebrew)

I'm using neoclide/coc.nvim as language client support in my vim editor. However, when I move the cursor to self:foo() inside the module:bar() function, and try gd key, which is mapped to <Plug>(coc-definition), it will output the error about finding no definition.

local module = {}

function module:foo()
end

function module:bar()
    self:foo()
end

At least, when looking at the builtins, there are many cases where returnTypes aren't provided, even when the function returns a value. This means that the void return type should be an empty returnTypes array, not the absence of one

Variants are now supported: implemented as multiple signatures for one item

Also, there does not seem to be a builtin example of an "error" return type, aka return nil, my_err. I think we will represent those like so function a() ->! bool, extra_ret, but it's unfortunate that it won't be available in the standard lib.

I'm not willing to write my own but it's interesting that it doesn't exist to begin with
prior art:
https://github.com/trixnz/lua-fmt
written by the vscode server author
https://github.com/trixnz/vscode-lua

I edited $HOME/.luacompleterc

{
    "luaVersion": "5.1",
    "packagePath": "./?.lua;/home/user/.luarocks/share/lua/5.1/?.lua"
}

I did luarocks install --local lua-cjson
I added $HOME/.luarocks into package.path and package.cpath.

When I use vim I can autocomplete standard Lua functions(table.insert, io.open,etc), however I can not autocomplete anything from $HOME/.luarocks/share/lua/5.1, vim displays:

User defined completion(^U^N^P) Pattern not found.

So will lua-lsp be able to index all files under $HOME/.luarocks/share/lua/5.1 somehow? what about the C modules under package.cpath? I want to do auto-complete for all imported modules and my own lua files in addition to the working built-in Lua functions(e.g. os.open etc)

I'm using a library that use a specific require path like love2d, and it raise error when trying to jump to definitions from another file. How to configure to work with this?

I'm using neovim and the LanguageClient-neovim plugin, and setting g:LanguageClient_rootMarkers = ['main.lua',] doesn't work.

If I'm executing this command:

luarocks --local install --server=http://luarocks.org/dev lua-lsp

than I'm getting this error message:

Error: No results matching query were found for Lua 5.4.
To check if it is available for other Lua versions, use --check-lua-versions.

and if I try this command:

luarocks --check-lua-versions

than this pops up:

Usage: luarocks [-h] [--version] [--dev] [--server <server>]
       [--only-server <server>] [--only-sources <url>]

Error: unknown option '--check-lua-versions'

What am I doing wrong? I've installed lua from the official arch linux repositories and luarocks from the official arch linux repositories as well.

I installed lua-lsp with luarocks install --server=http://luarocks.org/dev lua-lsp. Starting lua-lsp in the command line results in the following error:

Thank you for having a look. Let me know if there is any further troubleshooting I can help with.

macOS 10.13.4
Lua 5.3

The package over on luarocks.org is 2 years old, and there have definitely been commits since then. The version there is still missing the rockspec update to include the missing formatting module, so formatting is broken, which is how I noticed.

Sooooo publish master to luarocks.org, please?

Any idea how I'd integrate this with the neovim built-in LSP?

I'm using lspconfig, but they only have a config for the sumneko Lua lsp, which IMHO is far too complex to set up just to get an LSP (you have to install several dependencies and build from source).

I'd much prefer to use this one, but I'm not sure how to configure it with the neovim built-in LSP?

How To Solve It？

Installation works by changing the protocol to SSH

$ sudo luarocks install --server=ssh://luarocks.org/dev lua-lsp   # works

Installation fails with HTTP URL which is currently suggested in lua-lsp README

$ sudo luarocks install --server=http://luarocks.org/dev lua-lsp   # fails
...
fatal: remote error:
  The unauthenticated git protocol on port 9418 is no longer supported.
Please see https://github.blog/2021-09-01-improving-git-protocol-security-github/ for more information.

This change will be made permanent 2022-04-16. We're currently on brownout period, so the old command will work intermittently.

I'm not familiar with luarocks, simply providing the command that worked for me on Debian 11-Bullseye. I noticed the error while writing installation instructions for Micro editor's new LSP Plugin. It seems that Lua-lsp works to some extent with this Micro's LSP plugin, supporting linting (in the left side gutter) and alt-D jump to definition inside the same file.

Is this project still maintianed?

Hi,

I am trying to clean up my configs and I am wondering if I can put luacompleterc under XDG_CONFIG_HOME? :)

The error message that i am getting is "No language server command found for file type lua". Lua-lsp is installed and is in the path. Any idea what i could be doing wrong?

Thanks

I guess this is easy to fix, but i'm not proficient enough with luarocks to do it myself.

I am trying to bring some updates to nixpkgs (NixOS/nixpkgs#172096) and one of the problems is that lua-lsp requires dkjson ~> 2.5 but I would like to update dkjson to 2.6.

Is it possible for you to update the dependency? (As a small motivation: 2.5 was released 2014 and 2.6 was released in 2021).

Ideally, we should update our grammar to support the new features at the same time that we port to lua 5.4 as a runtime
