Axe Interpreter

[calc84maniac]

As far as I know, it won't be able to use Axioms or Asm(), since there's no z80 emulation (and some Axioms and Asm() statements might rely on TI-OS, which isn't there either)

[DJ Omnimaga]

Ah right I forgot about Axioms. Hopefully it can run games like Axe Tunnel, though, or even some of the large projects (assuming all sub-programs are in the same folder)

[calc84maniac]

And I guess GetCalc() would directly access .8x* files in the same folder... that would be cool

[DJ Omnimaga]

Indeed that's what I thought, and of course sub-programs/routines

Progress report:

So, I essentially have to rewrite a chunk of my program.  Basically, the story is, I'm first converting text into a sort of tree -- lists containing lists containing lists.  Unfortunately, that format won't allow me to easily code in goto statements -- there are ways to hack out a solution, but they're all slow and brittle. 

So I'm rewriting my code to first create a tree then convert it into a single flattened list so I can easily jump to a line number.  Which is a pity, since I thought my whole recursive scheme for running the tree was cool (I like recursion). 

I'm also angsting over whether or not I should turn my tree into objects containing objects or just keep them as nested lists.

You know, gotos are generally seen as evil, but I never realized they were diabolical to implement too

For the name......how about Halberd?

[DJ Omnimaga]

I'm glad this is still progressing. Hopefully you can finish this.

I revamped how I handle memory and graphics.

Full pointer madness is working, along with graphics (including grayscale and sprites).  I still have to implement all the different sprite variations (which should be easy), and redo scrolling (Horizontal/Vertical +/-).

On the lexing/parser side, I've been procrastinating and still haven't rewritten it to compensate for those blasted gotos

Does anybody know where I can get the font used for the TI-84?  (both the small one and the homescreen one?)

[Art_of_camelot]

Ti's website used to have a font available, you could check there. I'm unsure if it was accurate or just looked similar to what was on the calc. I'm pretty sure it was only one size as well.

Necropost!

Here's a shiny new youtube video:
<a href="http://www.youtube.com/watch?v=i2cjxqMY4bg" target="_blank">http://www.youtube.com/watch?v=i2cjxqMY4bg</a>
(it comes out a bit small, so try going to the actual video?)

...and the download link:

So, here are a list of changes since the last official version!

• The parser and interpreter have been completely remade so it can handle goto statements
• Grayscale
• Almost anything related to memory has been finished

...and the things I need to work on:

• Adding constants
• Adding sprites
• Working on speed

The list of all supported tokens can be found here:

so grey just displays in fixed colour until the next update?

this looks pretty snazzy indeed =)

EDIT: there wasn't a linux executable included, so i tried running the version in .src. it worked, but i kept getting unrecognised token errors, and it froze up at the end of the program

Erm, could you clarify what you mean by 'fixed color'?

If you're referring to how grayscale usually has a flickering/diagonal effect in real calculators, I'm probably not going to in the near future because I'm not really sure how to code something like that. 

[shmibs]

yes, that's what i was referring to. i don't think there will be any reason for you to change it. it would be a lot of work, and most programs would look better like this anyways.

[Michael_Lee]

Huh, that's a really weird tokenizing error.  I confirmed on my linux box: I'll go ahead and take a look at it (although it may take a week or so before I have time push the fix out).
