Language aware diff for Lua with integration into VS Code and GitHub

Hi there,

I am working on SemanticDiff, a programming language aware diff that hides style-only changes, detects moved code and refactorings. We just added support for Lua and would like to know what you think!

SemanticDiff parses the contents of Lua files to distinguish between relevant and irrelevant changes. This way it can, for example, ignore whitespace outside of strings or how a string literal is written (brackets vs. quotes). The idea is to generate a diff with less noise:

The VS Code extension is completely free and the GitHub App is free as well if used with public repositories or private repositories that have 3 or less contributors. If this sounds interesting, you can read the release blog post to learn more.

Looking forward to your feedback.

ZeroBrane Autocomplete Function?

Hi guys,

I've recently tried some other ide's but zerobrane just works great with lua & love2d.

However atom and vscode both have this thing where you type fun and it autocreates a function putting your line at the noscript, tab to switch to args and tab to switch to body.

Can someone help/direct/guide me to getting this on zerobrane?

Lua Language Server support for my 2D game framework

Hi everyone,

I wanted to share something I’ve been working on over the past few weeks. I’ve improved the Lua development workflow for my open-source 2D game framework, nCine, and put together a video to demonstrate it.

The updated workflow now includes:

- Autocomplete
- Type checking
- Full API documentation
- Debugger support

These features are made possible thanks to the Lua Language Server and the Local Lua Debugger, and they make noscripting a lot more efficient and enjoyable.

Here’s the video if you’d like to check it out:
🎥 https://www.youtube.com/watch?v=vyXqnrW5_5Y

If you’re interested, there’s more information in the video denoscription and on the project’s website: https://ncine.github.io/.

If you’ve used the Lua Language Server with other game frameworks like LÖVE, Solarus, or Solar2D, I’d love to hear your thoughts. Does this workflow feel on par with what you’ve experienced?

Help with lua returning a string for conky

Hello, i am looking to get some help with lua. I am trying to create a noscript to get and return weather data for conky. It mostly works as text until i tried to get it to display images. I have all the images it needs, but when i try to get it to load the images in conky instead of the image i jsut get the conky image command as text

This is the string i am using



-- Return the image path

return string.format("Location: %s\nTemperature: %d°C\nCondition: %s\nHumidity: %d%%\nWind Speed: %.1f m/s\n${image \"%s/.conky/lua/images/%s.png\"}",

city, temp, condition, humidity, wind_speed, os.getenv("HOME"), icon_code)

It displays as this

2d IDE for lua game dev that isn't pico-8?

Hey y'all, going through a bit of a confusing time rn as far as programming goes, was set on Lua but then switched to python, then to C, then to Go, then to common lisp, now back on Lua again. I was "learning lua" for a few months but made like zero progress because I didn't really do anything, so I want to change that this time. Anyway, back to what I was saying and sorry for the mini-rant lol, do any of y'all have recommendations for 2D IDE's/Engines for Lua game development that aren't pico-8? Also for anyone wondering why not pico-8, I has no moneys and also I don't like the constraints (I know why they're there, just not for me). If not I'll just learn Löve2d. Thanks!

"Programming in Lua" Journey

A while back I decided that I want to add lua binding to the project I'm working on (ceph). I'm mainly a C++ developer, and did not have any real experience with lua (except helping my kid with some roblox stuff...).

Initially, I picked lua since other projects in similar domains use it (nginx, haproxy, redis, etc.), but as I went on with my work I really fell in love with the language :-)

Currently, I have most of the bindings implemented on the Object Gateway of Ceph. But,I also figured out my knowledge of the language itself is very limited...

To try and fix that, I bought the "Programming in Lua" book and started to read through it and do the exercises (reading is pretty useless without the exercises). So far, I finished "Part I" (chapters 1 - 8), and documented in this repo: https://github.com/yuvalif/PIL

It has been great fun, but could be even better if done together with others. So, if anyone has also gone through these exercises, or want to give me some feedback, new ideas or want to tag along in this journey, it would be wonderful!

(I'll try to post regularly as I chew through the book)

Problems while installing LÖVR on EndeavourOS linux.

Hi, recently I tried to install LÖVR by compiling it from source. I cloned the repo and ran

$ mkdir build

$ cd build

$ cmake ..

$ cmake --build .

Unfortunately, docs don't list what to do after this and probably assume some level of CMake profficiency:
[https://lovr.org/docs/Compiling#linux](https://lovr.org/docs/Compiling#linux)

They say how to run LÖVR with VR, but that's not what I want to do right now.

Now, if i run `lovr` file from bin subdirectory, I get this error:

lovr: /usr/src/debug/glfw/glfw-3.4/src/window.c:868: glfwGetWindowAttrib: Assertion `window != NULL' failed.
Aborted (core dumped)

If I run `sudo make install .` I get different error:

CMake Error at luajit/src/cmake_install.cmake:81 (file):
file INSTALL cannot find
"/home/user1/dev/lovr/first_touch/build/luajit/src/luajit": No such file
or directory.
Call Stack (most recent call first):
luajit/cmake_install.cmake:47 (include)
cmake_install.cmake:48 (include)

I do not really use CMake that often and am not fluent in compiling software from source.

What have I done wrong? And what should I do now?

Thanks in advance.

Can a LUA noscript be used to replace a file that is within a ZIP file?

I am very new to this so I apologize if this is a stupid question.

I'm currently designing a Reaper Theme that will have it's own theme adjuster (the adjuster is the lua noscript), and I'm trying to plan ahead a bit and figure out what I should or should not be investing time into.

Something I wanted for the theme is the ability to swap out theme images using the noscript, similar to this noscript (it's called the Theme Assembler which is used in conjunction with the Theme Assembler Theme).

Normally, a theme and all it's files are zipped within a .ReaperThemeZip file (but it doesn't need to be). In order for the Theme Assembler noscript to work however the Theme Assembler theme must be unpacked.

Want I want to know is if it's possible to accomplish the same thing if the theme was in its zipped state with the .ReaperThemeZip. Basically to use a LUA noscript to drop in and replace images within the .ReaperThemeZip.

Help needed - luarocks test --prepare always erroring on Windows

I'm trying to install a package luarocks. Specifically I want to

1. clone my package
2. install all of its dependencies
3. install all of its test_dependencies
4. run the unittests (via busted)

My understanding is that I can do #2 and #3 by calling luarocks test my_package-scm-1.rockspec --prepare and then do #4 with luarocks test --test-type busted. #4 is working fine. My problem is with #3. And possibly #2.

I simply cannot seem to get luarocks test --prepare to run on Windows. It looks like despite the luarocks test --help documentation saying that --prepare does not run any tests and just installs dependencies, it looks like --prepare still actually does run some tests. In my logs I can clearly see Error: test suite failed

This is the GitHub workflow run: https://github.com/ColinKennedy/mega.vimdoc/actions/runs/12772422930/job/35601914793

And the logs are here

And the GitHub workflow file

From what I can guess from reading luarocks source code, it looks like unittests are running for some package, somewhere, and instead of showing the error it's just defaulting to the generic Error: test suite failed error message that can be seen in the logs.

[noob] Replace single space in between non-space characters with wildcard

How to replace a single space (` `) in between non-space characters with `.*`?

I'm writing a simple Lua wrapper (I don't know any programming) to rebuild the string that gets passed to rg (grep alternative) where a single space between non-space characters imply a wildcard. To use a literal space instead of the wildcard), add another space instead (i.e. if the wildcard is not desired and and a literal space is wanted, use 2 spaces to represent a literal space, 3 spaces to represent 2 spaces, etc.).

Example: `a b c d` becomes `a.*b.*c.*d`, `a b c d` becomes `a b.*c.*d`.

I have something like this so far `query:gsub("([^%s])%s([^%s])", "%1.*%2")` but it only results in `a.*b c.*d` (`word word word word` correctly becomes `worda.*wordb.*wordc.*wordd` so I don't understand why) .

-----

For handling literal spaces, I have the following:

local function handle_spaces(str)
str = str:gsub(" +", function(match)
local length = #match
if length > 2 then
return string.rep(" ", length - 1) -- reduce the number of spaces by 1
else
return " " -- for exactly two spaces, return one space
end
end)
return str
end
