It would be a good idea to develop LuaOnboard for PSP. It is more like a regular DOS console running Lua. The app could be written in Lua script. It prompts a line to input some Lua chunk and execute it after pressing Enter key or some other key. We need virtual keyboard or some external keyboard using SIO ports for input purpose.

With the app installed in your PSP, you could learn Lua language while traveling.

How is the idea? Has anybody ever tried to develop a similar one?

i was thinking about a similar idea.

it would be great to be able to code on the psp, like you can with a ti-83 programmable calculator.. i'm sure most of you have seen one of these, but basically it uses a menu system to group similar commands/keywords, for example, one menu for control statements IF, THEN, FOR, END, etc.. and another menu for logic statements OR, AND, XOR.. and so on.. basically, you have a menu entry for every possible keyword. this eliminates typing as much as possible.

this system works very well on the ti-83, partly because it has so many buttons.. the limited number of buttons on the psp would slow things down a bit, but i think with some well structured menus, you could probably do ok.. and with the increased screen resolution (and color), you have much more options when it comes to a menuing system.

for naming variables, you could have a menu option like "Define new variable", where you enter a variable name, and then it gets added to a menu.. that way you could just select it from a menu, instead of retyping it over and over. with a little work, you could eliminate typing from the main interface entirely, just going with a menu system instead.

this part of the design i have pretty well figured out. and it would be simple enough to have lua write code to a .lua file, and call it.. coming up with useful debugging tools would be harder, and probably done best with a modified lua interpreter, which is beyond what i can do at this point.

I was thinking of menuing system in lieu of keyboarding, too. In order to execute Lua chunk, we can use dostring() function for inputted chunk or dofile() funxrion to load small prewritten Lua scripts. The buffer for the console can be saved and later uploaded to PC for further work.

Many times we had some such ideas in Lua and wanted to try them on PSP while on road without having to wait 'til we got home to try them.

In the past, I developed similar apps for other platforms but without graphics. With LuaPlayer, it would be an ideal to develop the console app.

More brainstorming, folks?

Sounds like a neat idea.

Believe it or not, I think p-sprint would work very well for typing Lua Script. Once you start using it, you can get very fast - remember, it only takes twice the number of keypresses on a regular keyboard.

Since there are still available keymaps, I could easily make one optimised for Lua (i.e. bringing the most used symbols to the shortest combos) to the basic keygroup.

I use pspda for typing up lua on the road. its pretty simple.

Arwin, could you give us a link regarding p-sprint?

link, how about a link to pspda?

TIA

If you look around you'll find implementations in dosbox, Basilisk and Microwindows ...

I forgot where i got it but if anybody finds it tell me. it is very usefull. it has a text editor, image viewer, music player, paint, and file manager. in the mean time, this should work. http://www.mobiledeviant.com/forum/downloads.php?do=file&id=132
Im pretty sure it is the same text editor included in pspda

Yeah, the TI83-System would be great.
It is blinding fast, intuitive, and safe of typies.

Believe me, I know what I�m talking about.
(reference: http://www.ticalc.org/archives/files/fileinfo/297/29730.html )

Doing such an editor was a project I was going to start next month since I have to learn more about lua for that.
Anyway, if you need ANY support please let me know.

feature request: make the menu system editeable. If possible, please try using an ini file for it�s structure.

I do know that it is possible to call external C routines from LuaPlayer running on Windows but I don't know about PSP platform, tho'. I guess the possibility is in Shine's own domain.

Here is a new FAST text input concept using remapped VIRTUAL QWERTY KEYBOARD:

Feel free to use it in your Lua (and also other) Apps. And do not forget the credits .)
cheers, mrn
