'Fungus' Funge-98 diagnostics tool

(fungus.zip, 16,974 bytes)

This is release #1d of the Funge-98 test/diagnostic suite I've been working on, since the Befunge Diagnostics at Cat's Eye Technologies seem to have vanished. It still isn't finished yet, but is able to test for a plethora of features a Funge-98 (or Befunge-93) interpreter should support.

The tests are written as a series of Befunge-93 sized modules, which means that you can load each module into an interpreter (including Befunge-93 ones) for individual testing, should your interpreter fail to like the auto-loader program.

The current set of modules check the following:

• fspace - Check fungespace configuration
  
  • Check get/put with negative cell addresses to check for unlimited fungespace size
  • Compute the size of stack and fungespace cells, and their signedness
  • Ask the y instruction for the fungespace cell size
• b93 - Test simple befunge93 instructions
  
  • Check !, $, 0-9, :, ` work
  • Check edge jumps work
• string - Check stringmode works
  
  • Direction change instructions are disabled
  • Non-ASCII cells work
  • SGML or Befunge-93 spaces?
• math - Check maths
  
  • Check the signs of the % and / results
• f98 - Check funge98 instructions
  • Check ', a-f, k, s and z work
• f98space - Check funge98 direction/space related instrs
  
  • Check contents of ; gets skipped - direction changes, quotes, etc.
  • Check [], r, w, x
  • Check j - negative, zero, and positive arguments
• concur - Check concurrency stuff
  
  • 't' agrees with 'y'
  • IP id's are different
  • z is 1 tick, space 0 ticks
  • k is 1 tick
• sem - Check funge98 semantics
  
  • Check A-Z reflect
  • Check overlays work via the NULL and ROMA fingerprints
• stackstack - Check stackstack instrs
  
  • u transfers data in correct directions & orders
  • { and }: if the offset changes, whether stacks are created, etc.
• HRTI - Check HRTI fingerprint
  
  • Check instructions work
  • Provide simple benchmark
