Axe Parser
Omega 1.2.0

---

It's Thanksgiving, and this year, we can all give thanks for Axe living on! Just temporarily under new management.

New Features:

• Have the need for speed? Using #ExprOn will request that all following code and called Axe routines be optimized for speed instead of size! Using #ExprOff does the reverse. Currently this only affects a few Axe routines (*, Pt-On(), Pt-Change(), DrawInv, Horizontal+/-, >Hex), but more will come! Axe Fusion always uses the fastest Axe routines available.
• Continuing with the speed theme, DispGraphRecallPic has been added! It's the same as DispGraph and then RecallPic, but it's almost as fast as DispGraph alone.
• Fixed point division! Syntax is: /*
• Fixed point square! Syntax is: ²^r
• Labels and constant names can be up to 13 characters long!
• No longer corrputs the OS when unlocking flash!
• Even shinier commands list! BIG thanks to jacobly! I'm also trying to add size and speed data for everything; it's a work in progress, so please excuse errors/missing values for now.
• Full support for big endian variables.
• Signed min() and max(): just throw on an ^r.

Changed:

• Better string parsing, including spelling out multi-character tokens, more reliable "var", and "grp" (w) is now "tmp"; these arbitrary-size variables will be automatically deleted on exiting.
• Optimized most DispGraph variants: all but 4-level DispGraphClrDraw are smaller, which is larger because...
• 4-level DispGraphClrDraw is about 15% faster. Also, 4-level DispGraph is about 5% faster.
• Optimized >Hex, stdDev(), Horizontal-(EXPR), getKey(EXPR), ^-1, interrupts, and all archived variable routines slightly.
• Optimized more stuff that I forgot.
• nib{}^r now always reads from the half of memory your code exists in.
• inData(0,DATA) now returns 0, so no more adding 1 to all your key checks!
• ln(0) now returns -1, it seems slightly more proper than 255.
• Disp >Tok accepts the same argument type as Text >Tok.
• Added "signed" equal and not equal operators.
• Added optimizations for ^10, //0, and //-1, not that the latter two will ever be needed.
• The A-theta variables have been moved, so L₁ is now 768 bytes long by default.
• When pointed into a variable in RAM, the Y_1T and Y_2T variables will be updated automatically if the variable is moved.
• The X_1T and X_2T variables will act similarly when pointed into a VAT entry.
• The X_4T-Y_6T variables have been added.
• Slightly larger but faster multiplications by some large powers of 2.
• Fixed a bug when a string displayed in an app went offscreen.
• Fixed drawing sprites to arbitrary buffers.
• Fixed rectangle clipping.
• Fixed the size of the stdDev() subroutine.
• Fixed some Axe fusion-related bugs.
• Fixed some bugs with the token hook.
• Fixed some bugs with comments.
• Fixed some peephole optimization bugs.
• Fixed a silly typo in an error message.
• Fixed many errors in the command list.
• Fixed many other bugs that I forgot about.
• And probably introduced some bugs!

Axe Parser
Omega 1.2.2

I've been quite busy with school (and generally lazy to boot), sorry it's been so long since the last update. The Axe application is bursting at the seams, so it's difficult for me to fit in new language features, but I fit in a few. The primary focus of this release is to improve stability, so a lot of the new things in this version are application usability improvements and bug fixes.

If there are any outstanding bugs, even if you've reported them before, or if you find any new bugs, please report them in the Bug Reports thread. I'd like to get Axe to be as stable as reasonably possible, and you can help.

New Features:

• New command to call the OS keypad scanning function: getKeys (or getKeyS). A useful application is to put this in your custom interrupt so you can use getKey and getKey^r in your program like normal.
• New command to set the LCD's z-address: ZInterval #.
• New commands that suspend annoying things for the remainder of your program: Full^r and Full^rr. The former suspends any memory delays on non-83+ calculators and the latter suspends Horiz mode (forces a ClrHome upon execution and when your program returns). These commands will not properly restore the suspended settings if you use Return^r!
• Added a new form of calling inData() for which you specify the length of the data to check: inData(BYTE,PTR,SIZE). No issues when searching for zero!
• Axe no longer disables Horiz or G-T modes.
• APD can now activate, so accidentally leaving Axe running won't drain your battery so much.
• Error if application being compiled will be too large after the first pass instead of the second pass.
• Using lowercase letters in the output name header will throw an error when not compiling as an application.
• Generally more robust source file header parsing and validation, including being able to jump to errors in headers.

Changed:

• Renamed sign{} to signed{} and renamed stdDev() to strGet() for clarity.
• Optimized direct key input slightly. ***If your calculator has had key port (delay) problems related to getKey(#), please test that direct key input works.***
• [Jacobly] Greatly optimized the speed of high-order and fixed-point multiplication.
• [Jacobly] Optimized circle drawing slightly.
• Changed the default varaible location again, this time into smallEditRam. The previous location conflicted with MathPrint.
• Reorganized the command list slightly.
• Fixed sometimes getting stuck in an infinite key wait loop after an error.
• Improved the error dumper with more debugging information for me!
• FIXED THE SEEMINGLY RANDOM COMPILING FROM ARCHIVE ERRORS THAT HAVE PLAGUED AXE SINCE 1.0.0! Big thanks to shmibs for helping me debug this!
• Fixed some parsing issues with For()^r.
• Fixed 3-argument HLine() and VLine().
• Fixed inverted circle drawing.
• Fixed ?Hex and archived value reads in programs compiled for Axe Fusion.
• Fixed an error with the use of special OS variable names, like Pic2, in strings.
• Fixed an obscure bug caused by putting r₂-r₆ immediately before a function call.
• Fixed error scrolling with zStart crashing for archived source programs that span multiple archive pages.
• Fixed 8-character names immediately throwing an error when trying to compile applications.
• Fixed multiple bugs with application writing, including not recognizing when there was no space for the application.
• Fixed an error being thrown when compiling a program whose target already exists in archive after a fresh garbage collect. Thanks to thepenguin77 for helping me debug this!
• Fixed other bugs I forgot about.
