v0.2 alpha 2023-03-20

  • Add COMPILE-ONLY.
  • Catch exceptions in AUTOBOOT.
  • Embed the bootstrap Forth code in forth-skeletal and parse out of memory instead of reading from a file. This will allow INCLUDE and others to be implemented in Forth.
  • Turn AUTOBOOT into a deferred, so what happens automatically at startup can be customized (by default this is a no-op - should it be something like :NONAME INCLUDE AUTOBOOT.F ; ?)
  • Add support for double literals (such as 123.) to the interpreter.
  • Improve error reporting. The source line number, line contents and parse position are displayed along with (if available) a message for the exception number.
  • Added value UNIT used by OPEN-FILE as the unit number. Defaults to 8.
  • CORE: add ENVIRONMENT? and MARKER. CORE is now feature complete (with the exception of the obsolescent [COMPILE]).
  • DOUBLE: add 2CONSTANT, 2LITERAL, D>S.
  • SEARCH: add ALSO, DEFINITIONS, FORTH, GET-CURRENT, GET-ORDER, ONLY, ORDER, PREVIOUS, SET-CURRENT and SET-ORDER. SEARCH is now feature complete.
  • STRING: add UNESCAPE.
  • TOOLS: add SEE (incomplete).
