Nick Briggs 4104219ee5 Avoid intermediate buffer and bitblt Lisp screen changes directly into the texture pixels
Using SDL_LockTexture/SDL_UnlockTexture we can gain more direct access to the pixels of the
texture and update them directly from the Lisp screen bitmap.

At the same time, for both the rendering case and the display surface case,
update the pixel format used to be either the first (presumably preferred?)
format for a texture, or the surface format of the window.

Use the SDL routines to pick out the pixel value for Black and White based on the
destination it will be placed in.

Maiko

Maiko is the implementation of the Medley Interlisp virtual machine, for a byte-coded Lisp instruction set and some low-level functions for connecting with Lisp for access to display (via X11) and disk etc.

For an overview, see Medley Interlisp Introduction.

See the Medley repository for

Bug reports, feature requests, fixes and improvements, support for additional platforms and hardware are all welcome.

Development Platforms

We are developing on FreeBSD, Linux, MacOS, and Solaris currently on arm7l, arm64, PowerPC, SPARC, i386, and x86_64 hardware.

Building Maiko

Building requires clang, make, X11 client libraries (libx11-dev). For example,

$ sudo apt update
$ sudo apt install clang make libx11-dev
$ cd maiko/bin
$ ./makeright x
  • The build will (attempt to) detect the OS-type and cpu-type. It will build binaries lde and ldex in ../ostype.cputype (with .o files in ..ostype.cputype-x. For example, Linux on a 64-bit x86 will use linux.x86_64, while MacOS 11 on a (new M1) Mac will use darwin.aarch64.
  • If you prefer using gcc over clang, you will need to edit the makefile fragment for your configuration (makefile-ostype.cputype-x) and comment out the line (with a #) that defines CC for clang and uncomment the line (delete the #) for the line that defines CC for gcc.
  • There is a cmake configuration (TBD To Be Described here).

Building For MacOS

  • Running on MacOS requires an X server, and building on a Mac requires X client libraries. An X-server for MacOS (and X11 client libraries) can be freely obtained at https://www.xquartz.org/releases

Building for Windows 10

Windows 10 currently requires "Docker for Desktop" or WSL2 and a (Windows X-server). See Medley's README for more.
