* Add experimental SUBR to call nanosleep() for experiments in reducing CPU load This adds a SUBR, sb_YIELD, value (octal) 0322 which takes a single number 0..999999999 which is the number of nanoseconds to pass to nanosleep(). The return value is T if the call to nanosleep() was executed or NIL if it was not (argument out-of-range, or other error in getting the number from the argument). To use this experimental SUBR in a sysout you should: (SETQ \INITSUBRS (CONS '(YIELD #o322) \INITSUBRS)) then you can define functions that use that SUBR: (DEFINEQ (BACKGROUND-YIELD () (SUBRCALL YIELD 833333))) (COMPILE 'BACKGROUND-YIELD) (SETQ BACKGROUNDFNS (CONS 'BACKGROUND-YIELD BACKGROUNDFNS)) * Update to use subrs.h newly generated from LLSUBRS The subrs.h include file is generated by WRITECALLSUBRS based on the \INITSUBRS list. This update provides for the new YIELD subr in the generated file, and makes some necessary updates to the C code implementations for some subr names which have changed.
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
- Issues (note that maiko issues are there too)
- Discussions (Q&A, announcements, etc)
- Medley's README
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 x11dev
$ cd maiko/bin
$ ./makeright x
- The build will (attempt to) detect the OS-type and cpu-type. It will build binaries
ldeandldexin../ostype.cputype(with .o files in..ostype.cputype-x. For example, Linux on a 64-bit x86 will uselinux.x86_64, while MacOS 11 on a (new M1) Mac will usedarwin.aarch64. - If you prefer using
gccoverclang, you will need to edit the makefile fragment for your configuration (makefile-ostype.cputype-x) and comment out the line (with a #) that definesCCforclangand uncomment the line (delete the #) for the line that definesCCforgcc. - 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.
