luacheck VS IntelliJ-Luanalysis

Not directly related, but luacheck can also help with this.

Yeah. While you're at it, make a habit of running luacheck on your files as it helps catch a lot of these issues that can sneak in by mistake: https://github.com/mpeterv/luacheck

Using something like https://github.com/mpeterv/luacheck might be helpful too. Will check all the files in a directory and will let you know which one might be problematic.

I'm trying to setup luacheck (via null-ls) to run alongside sumneko-lua (via nvim-lspconfig).

Most of the time nothing is used. The thing is that iterating is so quick, that you find the problems really fast.

Although, I've been using luacheck https://github.com/mpeterv/luacheck. It is quite nice, but you have to write down the global variables by hand on the config file.

Check out luacheck. It can help spot typos or mistakes you've made and warn against anti-patterns. I'd honestly only look into setting it up locally because there's no benefit to putting it in a CI pipeline unless you have one for another reason IMO. This should be all the config you need:

Sadly the scenario that the successor feature is intended to alleviate has very much become reality. The creator of Luacheck (Peter Melnichenko) passed away a couple of years ago, and ever since then the GitHub repository has been in a state of limbo. Multiple unofficial forks have come and gone, but Peter's is still the first result on Google if you search "luacheck". It isn't even possible to change the README or pin an issue to get people's attention about the fork; to this day people are still posting issues to the old repo.

And Luacheck is "the" Lua static analysis tool that pretty much everyone uses, so it's a very significant issue.

You are probably right, but luacheck is well aware of which global variables are built-in and it has special comments, such as -- no global or --ignore in case you very want to overwrite them.

Calling your function self is as much bad practice as calling it print. Use luacheck to avoid such mistakes.

Because of compile-time type safety / static analysis. And I say this as the author of an IDE that bolts those features onto Lua: https://github.com/Benjamin-Dobell/IntelliJ-Luanalysis

I want to start adding support for Lua derivatives to my IDE (which adds static type checking to Lua - inference, structural & nominal types, generics etc. (Luanalysis - https://github.com/Benjamin-Dobell/IntelliJ-Luanalysis/)

I feel like plugin support would be best but I've no idea how that's supposed to work in the presence of a predefined grammar. There's also so many variants I don't think there's a good way to build composite grammar.

Does anyone have any ideas about how to extend language parsing? For reference, I'm using https://github.com/JetBrains/Grammar-Kit.

There's also my IDE which just bolts on types (both structural and nominal) to regular Lua - no transpiling as the types are defined with comments (or inferred).

Unfortunately, I haven't been able to give it as much attention as it deserves recently.

What do you mean by no lambdas exactly? Lua supports anonymous functions and those functions capture variables from their outer scope.

I use functional programming extensively in Lua also. Could you elaborate on what it doesn't permit?

Integers were introduced in 5.3.

Assigning operators? It has metatables, you can absolutely implement your own operators.

If you want static typing you can use my IDE: https://github.com/Benjamin-Dobell/IntelliJ-Luanalysis/

Granted, my IDE is incredibly opinionated and not for everyone.

Also, Lua is not my favourite language to use, doesn't even make top 3. However, the robustness of its design, considering its simplicity, is incredibly elegant.

Anyway, you can find screenshots in the project's README on Github: https://github.com/Benjamin-Dobell/IntelliJ-Luanalysis

Current Role: CTO @ Snaploader

Salary Expectation: $200,000+ USD

These days I describe myself as a full-stack developer, but I’ve also plenty of professional experience with mobile (native + React Native), infrastructure, ops, game development, tooling and reverse engineering. In my free time I also tinker with embedded systems. I’m an avid open source contributor, but also maintain many of my own open-source projects e.g. a Lua IDE which statically type checks Lua (https://github.com/Benjamin-Dobell/IntelliJ-Luanalysis).

I’ve 12+ years of development experience, the last six years I’ve been CTO of Snaploader, a small start-up in Australia which turns floor-plans and CAD drawings into real-time rendered 3D buildings that run in your browser (including mobile). HQ is interstate, thus the role has always been near 100% remote. There’s a team of 20+ 3D artists and sales, but development is a one man show. So I’m responsible for a pretty absurd amount.

I also occasionally take on casual consulting gigs, which typically come about from my open source contributions. Currently I’m consulting for Berserk Games. I work on their Lua language bindings, public API documentation, networking and tooling for the (user content centric) game Tabletop Simulator (Unity/C#). I also help out their developer community with support, libraries, documentation and example projects i.e. developer advocacy.

Please do peruse my Github. I’m after something senior where I can take some ownership, but ideally also contribute across a breadth of projects/technologies.

Me: Okay. I'm just going to prototype a game. Don't want to get carried away. I won't even write a game engine. I'll use Tabletop Simulator.

Friend: Sounds good. How's it going?

Me: Well. I needed to be able to debug my code. https://github.com/tts-community/moonsharp-tts-debug

Friend: Oh, neat. So your game is done now?

Me: Not exactly. I had to had in matchmaking by reverse engineering Steam. https://github.com/SteamRE/SteamKit/pull/704

Friend: Ah. Alright. Can I play it now?

Me: Nah, I was finding it hard to maintain code. I wrote a Lua code bundler. https://github.com/Benjamin-Dobell/luabundle

Friend: Sweet.

Me: Yeah, but I decided to integrate it into the official tooling. https://github.com/Berserk-Games/atom-tabletopsimulator-lua/...

Friend: I'm sure the community will be thankful.

Me: I hope so. I now run a small community of TTS developers. https://github.com/tts-community/

Friend: Right. You must be done by now.

Me: Nah, I couldn't statically type check my code. So I wrote some types. https://github.com/Benjamin-Dobell/tts-types

Friend: Seems unnecessary for a prototype, but sure.

Me: I had to write my own IDE to use them though. https://github.com/Benjamin-Dobell/IntelliJ-Luanalysis

Friend: Right... So how'd the game going then?

Me: Oh, I'm not doing that anymore. I now consult for Berserk Games, developers of Tabletop Simulator

Friend: ...

Atom (most basic), Vscode with emmylua (debugging) and tabletop simulator lua, or Intellij with luanalysis (type safety). all are really good depending on your use case. I have never used the scripting window, even for simple scripts.
