roadmap - marinus-lab/z88dk GitHub Wiki

Release Schedule

z88dk will be released on the Sunday of the second week of July and January, thus the next release dates is:

  • v1.10 - 10/1/2010

Roadmap

The roadmap contains a list of features that should be in a given release:

v1.9 - July 2009

  • stdio New implementation of stdio available for testing on selected target(s). The main purpose of the rewrite was to make the library 100% asm, reduce memory footprint, introduce support for multiple device drivers, make it possible to integrate sockets / file descriptors fully into the stdio model, and supply some missing functionality demanded by standard C.

  • strings

    • add strlcat()
    • add strlcpy()

  • stdlib

    • add qsort(), will accompany existing non-standard (but faster) l_qsort()
    • add bsearch(), will accompany existing non-standard (but faster) l_bsearch()
    • itoa() and ltoa() changed to output variable radix numbers which is more inline with modern implementations of these functions

  • input

    • fix in_GetKey() which was dropping keypresses unnecessarily
    • in_Wait() and in_Pause() now measure time in milliseconds

  • lib3d (mostly coming from the MSX HTC GFX lib)

    • new 'stencil' object for fast convex polygons dithered fill
    • optimizations in size and speed
    • new vector functions
    • big inprovements in managing triangles

  • New targets

    • add support for Galaksija, including lo-rez graphics and 1 bit sound support
    • add support for TRS80, including lo-rez graphics and 1 bit sound support

  • C128

    • "SG Tools" are now part of z88dk; SID sound, low and high resolution GFX, timers and much more.
    • much better base graphics support
    • support for both "CP/M" mode and C128 BASIC mode binaries

  • Amstrad CPC

    • fixed a bug in the ROM interposer causing crashes in many functions
    • many target specific improvements
    • much better base graphics support

  • MSX

    • add functions coming from "GFXLIB" by Rafael de Oliveira Jannone
    • much better base graphics support
    • target specific code for DSP sound, graphics and controllers.

  • CP/M

    • improved fcntl

  • TI83+ and TI84

    • appmake output binary format changed

  • ZX81

    • Functions to exchange integer values with BASIC

  • ZX Spectrum

    • target specifib lib slightly fixed and rearranged
    • ROM building support

  • Rabbit Control Module

    • add flash handling

v1.10 - January 2010

  • crt0 (C startup code)
    • Move all library static variables to the crt0s
    • Redo crt0s so that all of them can easily separate data and code areas
  • stdio
    • Migrate all targets to the new stdio
    • Add floating point converters to new stdio
    • Integrate sockets API for new stdio
    • (?) Integrate FAT16/32 middleware for new stdio
    • (?) Add some intelligence to the compiler to that it can automatically select the minimal set of stdio features needed in a compile
  • math
    • Ensure that all floating point packages support the same group of mathematical functions
    • Perhaps standardize how each floating point package is called by the compiler
    • Make it easier and clearer as to how a new floating point package can be added to the compiler

Future

Features on the to-do list that may or may not be promoted to a release above.

  • z88dk package

    • CVS snapshots available on a frequent basis
    • Removing all the old documentation and ship a copy of the wiki with the kit
    • Updated examples

  • Compiler / Assembler / Linker

    • Clean up of the compiler
    • Some more magic in the compiler (not sure what yet!)
    • Cleanup some ugliness in the zcc driver
    • Migration to MPM as the assembler of choice
    • Give user control over declaring multiple code and data segments
    • Introduce a standard bank-switching model so that the compiler can automatically create projects larger than 64k in size

  • Miscellaneous

    • z88 spectrum screen emulation
    • Test framework in place for generic library functions
    • Cleanup the headers (similar to what Alvin has done to spectrum.h)

  • Abstract Data Types

    • add singly-linked list
    • add static hash table
    • add avl tree
    • add map type
    • check into whether it makes sense to follow C++'s STL model

  • Input

    • port to CPC, MSX

  • SP1 software sprite engine

    • port to CPC
    • port to MSX, Timex hi-colour mode

  • math

    • look into adding numerical algorithms

  • stdio

    • add compression / decompression filters to new stdio
    • grow device driver library

  • stdlib
