I've released version 0.4 of Mimas, an on-calculator IDE for writing assembly programs on the TI-83+/84+.

First, this release fixes a number of long-standing bugs and annoyances:

 - incorrect definition of fullScrnDraw
 - plotLoc flag should be cleared upon exiting
 - div/mod operators
 - detection of dependency loops
 - archive-on-exit when multiple programs were edited
 - support for IFDEF/IFNDEF in asmto8xv

Second, I've made a few improvements to the conversion tools:

 - use a default output filename for 8xvtoasm (instead of standard output)
 - prompt before overwriting output files
 - asmto8xv accepts options --case-sensitive, --preserve-case, and --fold-case

And third, I've added some new features in the form of "plugins":

 - library symbols menu
 - instruction info popup
 - scroll bar

The plugin concept is something of an experiment.  The idea is that this way I can add new, optional features, while keeping the base application the same size.  I'm interested to see what folks think of this - is it too complicated?  Is it worth the (not insignificant) extra effort of continuing to add features this way?

As always, I welcome your comments, suggestions, bug reports, flames, etc.

Woot, gotta transfer this to my calcs soon. Looks great!

Craps. I blew up my link port so I cannot send this
Oh and another request you might add in a next release: Empty lines. I find it quite useful if you can add empty lines to organize your code.

I'm not opposed to the idea, but I'm pretty sure you're reading that wrong.  It's not that execution is allowed on page 80, but that it would be allowed in the first kilobyte of page 82 if the execution limits did not wrap around at 32k (see port 21.)

It's not at all difficult to run large programs on the SE/84+: you can temporarily copy page 80 to page 83 and set port 5 to 3.  Of course, you can't use the system USB routines, and of course you need to restore the app base page table afterwards.

Blank lines: visually, I kind of like the use of blank comments instead, since they show you that there's something there (like the colons at the start of lines in the BASIC editor, if you see a semicolon at the bottom of the screen you know there's more to come, but if it's a blank line you know you're at the end of the section.)  UI-wise, maybe it would make sense for pressing Enter/Ins to automatically create a blank comment (if you don't type anything else.)

Ah, you're right.

And I would like to remind everyone that unlocking flash is dangerous and not to be done lightly.  But that's a discussion for another time and place.

Wow, how did I not see this update! Mimas does indeed have a very well made interface and I definitely like to use it for the more complicated pieces of code. I can't wait to give it a try.

Could someone make a plugin for Mimas that's basically the Asm in 28 Days tutorial, so I could read asmin28days on-calc and on the go/at school with no computer?

Moody's Flash Book app is, perhaps, the best e-book reader for the TI-83+ series.

BTW is Mimas bootstrapped? Just wondering...

No, Mimas is written for ZDS. I don't think Mimas could build a 2-page app at once due to memory limitations. It also doesn't support directly writing to flash. It's certainly possible to build and sign apps on-calc, but he seems unlikely to implement such functionality since he seems to think screwing with flash is too dangerous.
