'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
