Research direction

Start by reviewing the linked issues #4180, #4259, and #4260, then compare pyk's current behavior with the Java outer parser described in this issue. Done means pyk kompile can parse required files, handle prelude.md unless --no-prelude is passed, and resolve main and syntax module names.

Description

pyk

For pyk to do outer parsing when invoked by pyk kompile, there are a few major steps it needs to perform:

  • runtimeverification/k#4180
  • Parse files included with requires clauses
  • Parse and add prelude.md to the definition unless --no-prelude is passed
  • Resolve the main/syntax module names.
  • runtimeverification/k#4259
  • runtimeverification/k#4260

This should be the absolute minimum that needs to be done by pyk. There are some other checks and transformations that get done in the java outer parsing. It may be possible to move these further down the compilation pipeline. See https://github.com/runtimeverification/k/issues/4131
