Announcements And Comments > DSLua - a Lua runtime for Nintendo DS

#73351 - waruwaru - Sat Feb 25, 2006 12:28 am

You don't know C/C++, but you want to write some programs for your DS? Well, learn Lua and write scripts to run using DSLua! Here is version 0.1 (preview build) for you to play with. Version 0.1 supports some basic text functions, and functions to read dpads/stylus input. Currently it will only work with devices support by Chishm's FAT driver (devices like GBA Movie Player and M3 CF) though. Enjoy!

Download version 0.1 preview here.

Edit: Got it working in the DesMuMe. ;)

Neat. I like this idea better than making another BASIC variant. Lua is arguably just as easy, it's portable, it's standardized by virtue of the fact that there's a reference implementation, and it has very modern features (like closures and coroutines) so advanced programmers won't feel limited.

Thanks! I am a Lua novice, but from what I have seen, it sure is very easy and very powerful. :) What people are doing on PSP's Lua Player sure look like fun.

awesome news, lets hope the DS can have releases like the masses of Lua Releases for the PSP,

good luck with the player :)

Thanks! I hope people will find it fun and useful too. :)

Will there be a version supporting program entry through an on-screen keyboard? That's one way TI graphing calculators became popular: kids could program games on them during downtime in class.

I hope that was ironic.

#73605 - sajiimori - Sun Feb 26, 2006 9:45 pm

Why should it be ironic? Removing the technical restrictions to making games is a good thing.

The on-screen keyboard idea sounds fun. You'd probably want to make a crash-proof version of the DS IO library so it could stop and print an error message instead of locking up. Wouldn't want to lose all your code every time you make a mistake. :)

Sounds to me like he was mocking those PSP demos.

Hmmm, that sounds like a great idea! I will put that on my to do list. I was thinking once I implement the file read/write functionality, a simple editor written in Lua would be a quick solution. :)

Good point. :)

I agree about removing technical restrictions, and the problem is not LUA or the homebrew created, but rather the sites making it big head lines, eg."Screen Test v0.1" etc. Besides, LUA reminds me of Visual Basic for the windows platform. If that is a good thing, I rest my case.

#73650 - sajiimori - Mon Feb 27, 2006 5:43 am

If Lua reminds you of VB, that shows how little you understand Lua. It's more closely related to the likes of Lisp or Smalltalk.

#73653 - modrobert - Mon Feb 27, 2006 5:55 am

Was thinking about the results now, not programming logic.

#73666 - sajiimori - Mon Feb 27, 2006 7:56 am

The results being what?

#73674 - keldon - Mon Feb 27, 2006 10:20 am

I'm guessing "Screen Test v0.1"

#73713 - sajiimori - Mon Feb 27, 2006 7:40 pm

Nah, it couldn't be that because it has nothing to do with the language and everything to do with what you choose to pay attention to...

#74187 - HtheB - Fri Mar 03, 2006 8:53 am

when is the 0.2 availeble for download? :)

Sorry to keep you all waiting, work is kickin my behind at the momment... :( I planned to release 0.2 after I get more functionalities in, so hopefully something t this weekend.

Small update of what's coming in 0.2:
- implemented the GBFS file handles, so SD folks can use that for now
- with GBFS working, you can run DSLua on DeSmuME :)
- better error reporting for some crashes
- remove the START key wait after script is executed
- misc other small fixes

Chishm's has released a new FAT driver, so I might integrate that in as well.

By the way, DSLua.com had a face lift, hope you guys like it. ;)

Version 0.2 is now available. Added support to run from emulator/not-yet-supported-hardware (using GBFS), and some basic graphics functions. Enjoy!

Version 0.3 adds functions to create and manipulate spites. :) Same as the previous version, this version comes in GBFS and CF flavors. The GBFS version runs well on DeSmuME emulator. :) Download it directly from DSLua.com
