v0.15.0

• Updated the LSP support to only calculate possible completions once.
  • Since we only complete on the standard library this can't change.
  • Reported in #111, resolved in #112.
• Updated our CI process to run the lisp-specific test-cases on PRs
  • Implemented in #113
• Added string<, string=, and similar methods.
  • Implemented in #116.
• Added flexible sort-by method
  • Also implemented in #116.
• Implemented cos, sin, and tan, as well as variants along with pi.
  • Implemented in #117.
• Added extra argument testing to (random) and (base)
  • With test-cases and fuzz-testing for more fixes.
  • Implemented in #118.
• Fixed crashes with empty special forms, e.g. "(print (do))" and (print (let*())).
  • Fuzzing now looks good, though of course it is impossible to say:
    • fuzz: elapsed: 19h4m10s, execs: 5319853 (303/sec), new interesting: 492 (total: 4095)
    • fuzz: elapsed: 19h4m12s, execs: 5319918 (40/sec), new interesting: 492 (total: 4095)
• Allow loading a file with "(require 'foo)"
  • This will load foo.yal, and return nil if that file is not present.
  • Reported in #114, and implemented in #119.
• Added stack:push, stack:pop, etc.
  • Implemented in #120.
• Added a config-package, holding helpers for STDIN/STDOUT.
  • These are used by (read) and (print)
  • Implemented in #123, after a broken attempt in #121.
  • Added STDERR and a -debug flag in #125.
• Added (version).
  • Reported in #122, implemented in #124.
• Added hash/digest functions in #126
  • (md5), (sha1), and (sha256).
• Hashes are converted to strings with their keys sorted.
  • Implemented in #127
  • This allows the following code to return "true", as expected:
    • (eq { :name "Steve" :surname "Kemp" } { :surname "Kemp" :name "Steve" })
