How to load trial in clasp

• get newest clasp and build
• fork https://github.com/kpoeck/trial.git into ~/quicklisp/local-projects/
• fork https://github.com/kpoeck/3d-vectors.git in ~/quicklisp/local-projects/
• fork https://github.com/Shirakumo/glsl-toolkit.git in ~/quicklisp/local-projects/
• in glsl-toolkit do the following change in grammar.lisp(I fixed that locally in clasp, pr pending)

(define-operator-objects
  == != = += -= *= /= %= <<= >>= &= ^= \|=
  ++ -- << >>  ^^ \|\| && <= >= < >
  + - * / % & ^ ! \|
  \( \) \[ \] \{ \} \; 
  #-clasp \. #+clasp |.|
  ? \: \,)

• compile cl-jpeg without the ast interpreter (see https://github.com/clasp-developers/clasp/issues/727)

build/clasp
(load "~/quicklisp/setup.lisp")
(setq clasp-cleavir::*use-ast-interpreter* nil)
;;; be very patient, needs 1 hour on my machine
(ql:quickload :cl-jpeg)

• load trial

build/clasp
;;; be very patient
(ql:quickload :trial)

• try it out

;;; I had to delete :trial from the dependencies in the following :asd, don't know yet whether this is a clasp error
(ql:quickload :trial-glfw :verbose t)
(trial:launch 'trial::workbench)
