  4. Try the J source code, like https://github.com/jsoftware/jsource/blob/master/jsrc/v.c F1(jttable){A z,zz;I r,wr; F1PREFIP;ARGCHK1(w); // We accept the pristine calculations from ravel wr=AR(w); r=(RANKT)jt->ranks; r=wr<r?wr:r; // r=rank to…

  10. APL/J/K C-sources (perhaps by Roger Hui): https://github.com/jsoftware/jsource/blob/master/jsrc/a.c and other *.c files Niklaus Wirth, Verilog: http://people.inf.ethz.ch/wirth/FPGA-relatedWork/RS232R.v all of ioccc)

  15. I'd add to this family the J system, ver. 7 - https://github.com/jsoftware/jsource . A good example of creating a DSL and then efficiently using that. "Never had a memory leak from day 1 (Roger Hui)" (written in C).

  17. That's actually about as readable as the full J interpreter source code. https://github.com/jsoftware/jsource
    comment by messe · 2017-06-02 · in J one-page interpreter fragment (1992)
  18. I hope you don't have a stroke: https://github.com/jsoftware/jsource/blob/master/jsrc/cip.c ...just one of the many source files that make the interpreter for the J language.
