I manage to embed lua vm to my project!

Hey Lua community! I wanted to share a project I've been working on called RapidForge, it platform for building internal apps, automating tasks and creating web pages. Everything comes with a single binary and I manage to embed Lua VM into RapidForge. Big thanks to the Cosmopolitan project for making this possible!

With RapidForge, you can easily set up webhooks, schedule periodic tasks, and implement custom business logic using Lua. The platform takes care of the boilerplate for you, parsing request data automatically and making it available as environment variables (I’m planning to improve this further).

Lua is amazing language, I think its also a perfect language to experiment its small but performant and very easy to learn.

Why did this regex fail?

why did print(("PascalCase"):match("^(%u%l+)+")) returns nil while ^([A-Z][a-z]+)+ in pcre2 works.

Making a synth

I am a beginner programmer and I decided that I want to try and make my own synthesizer as a project. I know it might not be best for a beginner but I don’t have a time limit or anything, it’s just something I want to try. My question is: I was looking at different programming languages and stumbled upon Lua. So I’m wondering whether a project like that is worth making in Lua(as in if there are any problems I will encounter ) or should I do it in a different language?

Tiny Typing Utility Library

Hello y'all, I'm here to share a small lib I made for my own convenience and I think it might be useful to more people:

https://github.com/VicCAlq/moonkind

This is a simpler alternative to people who want the safety of a typing system but might not want to deal with using a language that compiles/transpiles to Lua or has any other kind of build step. I still want to work more on the feature of matching an "object's shape", but at the current point it can already be used.

It's already available on LuaRocks as moonkind, so a simple luarocks install moonkind suffices.

Any feedback is more than welcome :D

lua-docs: aesthetic documentation for the coolest noscripting language

Hey y'all, I'm pretty new to Lua, so when I tried to find documentation, it was either some outdated, scattered website tutorial or the lua.org manual that's incredibly long. I thought it'd be nice to have some good docs for the standard libraries!

And here it is: https://lua-docs.vercel.app

It's mostly copied from the manual but placed in a way that everything's easy to access. There's also a dark mode. Pretty cool, pretty cool. There's version 5.1 (which LuaJIT specs are at rn i think) and version 5.4 (most recent "major" release). There might be some errors with the formatting... but it should mostly be okay... (power of regex and command-f). People can always send a pr on the github repo for any basic issues with the markdown.

There's more dev notes at https://lua-docs.vercel.app/docs/about if you're interested.

Anyone interested in study how to write LUA with reframework?

Reframework is a powerful plugin for games and it support almost all CAPCOM games, but this plugin is lack of example so that it is difficult to master the programming skill, and I am only interested in joystick feedback so I only give example of joystick here. I want to ask about how to turn singleton of Reframework into LUA code.

1. Singleton for any key is press:

app.InputManager -> Reflection Properties -> app.inputDeviceFlag

2. Singleton for specific key is press:

app.InputManager -> AutoGeneratedItem -> app.InputState -> AutoGeneratedItem ->ArrayEntries[2\] ->

0x0:app.InputDeviceStateGamePad -> AutoGeneratedItem -> arrayEntries[32\] -> Reflection Properties ->

app.inputDeviceFlag

I have read the instruction of Reframework wiki, Reflection Properties item need special setting to access, did anyone here knew about it or is reframework bad at detecting joystick?

Help with Removing the Dot in Modern X Progress Bar (Lua Extension for MPV)

Help with Removing the Dot in Modern X Progress Bar (Lua Extension for MPV)

Hi everyone!

I’m using the ModernX interface for MPV, which is Lua-based. However, I’m trying to remove a dot in the progress bar that I find distracting. Does anyone know how to adjust this in the Lua code?

https://preview.redd.it/b3gr9a4p2uzd1.png?width=130&format=png&auto=webp&s=7b1494c28f3564717b473b6c0957407f1b4bccfe

I Use an older version of this so please download this from the google drive.
https://drive.google.com/file/d/1fFXiYIHrp0RlKLIRAs5fBIPvVMuaJDdL/view?usp=sharing

Sorry for the bother i cant upload it form here, i promise it is not a virus just a Lua. Google can scan it.

You can check with virus total too. it is safe

However this is the github for this extension it self

https://github.com/zydezu/ModernX/blob/main/modernx.lua

Would really appreciate any insights from those familiar with tweaking Lua for MPV!

Thanks in advance!

Bug Fixing for an OBS timer?

I'm trying to create a timer counter for OBS paired with a distance counter (Think "I walked 10 feet in 10 minutes".
What's odd is that it's working entirely for my OBS... And not anyone else??
I can run it well on my computer but if anyone else tries it, it either crashes their OBS, gives them a very strange number, or keeps counting without correctly adding the distance interval.
I've been trying to fix it for hours, but it's hard to debug when I can't seem to test it on my own computer. I'm very tired and there's a time limit to it, so I can't keep running random trials and asking my friends to test it. Could someone review my code and pinpoint why it may be continuing to count the time without adding distance when prompted?

obs = obslua

distance = 0

time_elapsed = 0

interval = 9 * 60

distance_increment = 1

timer_started = false

last_time = 0

text_source_name = ""

timer_interval = 1000



function noscript_denoscription()

return "Increments a distance counter by a specified amount every set interval. Displays Time and Distance."

end



function noscript_properties()

local props = obs.obs_properties_create()

obs.obs_properties_add_int(props, "interval", "Interval (minutes)", 1, 1440, 1)

obs.obs_properties_add_int(props, "distance_increment", "Distance Increment", 1, 100, 1)

obs.obs_properties_add_text(props, "text_source", "Text Source Name", obs.OBS_TEXT_DEFAULT)

obs.obs_properties_add_button(props, "start_button", "Start", start_button)

obs.obs_properties_add_button(props, "stop_button", "Stop", stop_button)

obs.obs_properties_add_button(props, "reset_button", "Reset", reset_button)

return props

end



function noscript_update(settings)

interval = obs.obs_data_get_int(settings, "interval") * 60

distance_increment = obs.obs_data_get_int(settings, "distance_increment")

text_source_name = obs.obs_data_get_string(settings, "text_source")

obs.noscript_log(obs.LOG_INFO, "Interval set to: " .. interval .. " seconds")

obs.noscript_log(obs.LOG_INFO, "Distance increment set to: " .. distance_increment)

obs.noscript_log(obs.LOG_INFO, "Text source name: " .. text_source_name)

end



function start_button()

if not timer_started then

last_time = os.time()

obs.timer_add(timer_callback, timer_interval)

timer_started = true

obs.noscript_log(obs.LOG_INFO, "Timer started.")

else

obs.noscript_log(obs.LOG_INFO, "Timer already running.")

end

end

obs.timer_remove(timer_callback)

timer_started = false

obs.noscript_log(obs.LOG_INFO, "Timer stopped.")

else

obs.noscript_log(obs.LOG_WARNING, "Timer not running.")

end

end



function reset_button()

distance, time_elapsed = 0, 0

update_text_source()

obs.noscript_log(obs.LOG_INFO, "Distance and Time reset.")

end



function timer_callback()

if not timer_started then return end



local current_time = os.time()

local time_diff = current_time - last_time

last_time = current_time

time_elapsed = time_elapsed + time_diff



if time_elapsed >= interval then

distance = distance + distance_increment

time_elapsed = time_elapsed - interval

obs.noscript_log(obs.LOG_INFO, "Distance updated to: " .. distance .. " km after interval reached.")

end



update_text_source()

end



function update_text_source()

local source = obs.obs_get_source_by_name(text_source_name)

if source then

local settings = obs.obs_data_create()

local minutes, seconds = math.floor(time_elapsed / 60), time_elapsed % 60

local time_string = string.format("Time: %d:%02d\nDistance: %d km", minutes, seconds, distance)

obs.obs_data_set_string(settings, "text", time_string)

obs.obs_source_update(source, settings)

obs.obs_data_release(settings)

obs.obs_source_release(source)

Lua Pandoc Citation Modifier

I'm trying to create a lua noscript that does the following with pandoc and its internal citeproc:

The current input is: \`(MPD; \[@Somereference2020 noparens\])\`

The desired output is: \`(MPD; Somereference, 2020)\` with the correct internal link to citeproc references.

I'm close, but I can't seem to wrangle removing the preceding space before \`noparens\` on the output.

Current output is: \`(MPD; Somereference, 2020 )\`

Note the space after the year which I've been able to debug to being the preceding space before the \`noparens\` (based on the debug output with carrots).

Thanks in advance to the Lua ninja ... Here's the code

function Cite(cite)
for i, citation in ipairs(cite.citations) do
if citation.suffix and pandoc.utils.stringify(citation.suffix):match("noparens") then
-- Debugging: Print the original suffix
print("Original suffix:", pandoc.utils.stringify(citation.suffix))

-- Remove 'noparens' from the suffix
local new_suffix = pandoc.List{}
for _, item in ipairs(citation.suffix) do
if item.t == "Str" then
-- Remove 'noparens' and trim spaces/commas
item.text = item.text:gsub("noparens", ""):gsub("^%s*,%s*", ""):gsub("%s*,%s*$", "")
if item.text ~= "" then
new_suffix:insert(item)
end
else
new_suffix:insert(item)
end
end
citation.suffix = new_suffix

-- Debugging: Print the modified suffix
print("Modified suffix:", pandoc.utils.stringify(citation.suffix))

-- Debugging: Print the original content
print("Original content:", pandoc.utils.stringify(cite.content))

-- Remove 'noparens' and unnecessary parentheses from the content
local new_content = pandoc.List{}
for _, item in ipairs(cite.content) do
if item.t == "Str" then
-- Remove 'noparens' and parentheses
item.text = item.text:gsub("noparens", ""):gsub("%(", ""):gsub("%)", ""):gsub("^%s*,%s*", ""):gsub("%s*,%s*$", "")
end
if item.text ~= "" then
new_content:insert(item)
end
end
cite.content = new_content

-- Debugging: Print the modified content
print("Modified citation: ^" .. pandoc.utils.stringify(cite) .. "^")

return cite
end
end
end
