##### ChipmonkeyLua v1.0
« on: 29. December 2013, 16:01:05 »
After CMBASIC, here's CMLua which is further developed now. All binaries are in one ZIP, too:
http://egsl.retrogamecoding.org/media/chipmonkey/CMLua.zip

Examples are included and as usual a few screenshots:

Well, I wasn't sure about this project but it turned up pretty cool. I can't see what else could be done if we're talking about old-school interpreter. Well done!

Thanks. BTW I forgot two examples.
plasma.lua:
Code: [Select]

And lorenz.lua (from bp.org):

I made a temporarily website out of the documentation: http://cmb.retrogamecoding.org/

There is one problem on Linux. Only exit() closes the program properly. When you try to close the window, it disappears, but ChipmonkeyLua is still running in the background. This is annoying when using external editor. After some time you may end with several ChipmonkeyLua processes running in the background and eating your memory and all you can do is kill them manually.

EDIT: Would it be possible to compile ChipmonkeyLua on Raspberry Pi?

I know of this problem. It's the same on Windows, too. I will take a look into it but found no solution, yet. It should be possible to compile CMLua on a RaspPi, I might try it in the emulator myself the next days ...

This is pretty icky first time I try it.
I really like some of it and I love the concept.
But it feels not so user friendly.

help() is a nice command, should be a suggestion under the startup system info.
Could use some functional arguments like number of columns to put the
help list into tabs, or a character or string to filter the commands.

The strange editing behavior could be alleviated if we could paste into the editor.

The line numbering is too strict, is there goto and gosub? No?
Then there really is no need for numbers, except if they are for debugging errors at line n.
You'd be better off with label system than strict line numbers.
I'm looking at OpenBasic as my new love like Lua.
Check out how it handles its label/line numbers, pretty nice. Its very much like old basic

10 x\$=inkey\$: if x\$ = "" then goto 10
becomes
10
x\$=inkey\$
if x\$= "" then goto 10

Wish I had that in 1983, and every time i have to convert BASIC programs.
Of course Open Basic doesn't have inkey\$ command! neither does MY-BASIC which is used inside of Ascii Hero Go
It's always something.

anyway.

edit() should maybe open a default text editor, maybe you can configure edit's options
with a parameter like edit('config')

You could probably remove some commands.
For instance fillrectangle() was done in Extended Basic like so

Code: [Select]
`Line(x1,y1)-(x2,y2),linecolor,linesize,pattern,fillcolor,pattern`Pattern at the end was some hex values that made textures inside the fill and thus a million scrolling games were born, in assembly.I only managed to make scrambled gibberish in those patterns.
You could of course make the pattern some reference to a string of ascii characters or an image file or something.

clear() doesn't clear the screen, should be cls() anyway, that's still used in windows console after 30 years.

Would love to be able to customize the whole UI and language for this thing.
How deep is the source? It's mostly Lua?

I recently posted the Aquarius Guide To Home Computing and Aquarius Home Computer System Extended Microsoft Basic Cartridge Instructions to archive.org.

Get the Virtual Aquarius emulator for windows for the experience of a lifetime ago.

Think you can fork Chipmonkey Aquarius?
Ideally it could be just some config files and scripts yeah?

Boot Loader BASIC has some new for 2014 commands on the Virtual Aquarius (30 years for a new BASIC wooo).
Like Joy() command you need in your life!

It also saves binary ROM files, kinda like luac I suppose.
Maybe you need some routine for self contained executable compiler.
A command like Boot Loader BASIC LDUMP. Ain't that an attractive command?

Keep up the awesome.

Line numbers are only for editing purposes. If you load the script into an external editor (I suggest Geany) you'll see that there are no line numbers saved. It's needed for lineedit (line number) to change a line.
It's retro and therefore user friendly as back in the 1980s.
The source code is 100% Free Pascal (using the units ptcgraph, ptccrt and ptcmouse) but it will not be released, yet.
clear() clears the graphics, cls() clears the whole screen. Try it: circle (400,300,300). Then clear(), you should still see the text but no circle.

In the next version the exit() function is working in scripts, too. So it is possible to e.g. do the following
Code: [Select]
`...script...inkey()exit()`

Okay guys the next version is online. It's available on the usual site: http://cmb.retrogamecoding.org/ and all binaries are again in one ZIP.

Changelog:
• activepage and visualpage for a second screen/backbuffer
• changed some examples to work with activepage/visualpage

Cool.  I know it's not your main project, but would it be possible to add two features to it? Possibility to get the color of a pixel and an option that saves a screen content to the file?

BTW What did you use to make the website? I like its simplicity and colors.

I will look into that. Retrieving a pixel colour won't much of a problem I guess, the other thing ... let's see.
Believe it or not, the page is done with pandoc (mark down language) -  (http://johnmacfarlane.net/pandoc/) - should be available in any newer Linux distro. This is my CSS (it's also in the download in documentation folder):

Code: [Select]
`pandoc -s -S --toc -c full.css documentation.md -o documentation.html `
Weird enough is that I have more fun developing CMLua and scripting in CMLua. (Developing the Yahtzee clone was a lot of fun!)

I will look into that. Retrieving a pixel colour won't much of a problem I guess, the other thing ... let's see.

That will do. If I get access to the colors, I could write in CMLua itself a function that saves the screen to .ppm file.

Believe it or not, the page is done with pandoc (mark down language)...

Thanx! I will definitely have a look at it.
