Prim Errors

Conceptual Stuff

This whole page is referring to the wip-middle-layer branch!

Even if it has to find the error partway through the prim for some reason (e.g. with running a lambda and failing when the lambda doesn't return a boolean), the prim can return a garbage value that indicates an error, and the middle layer can handle the error there.

The compiler needs to hand the token string of the prim into the middle layer, so that error messages know what to refer to the prim as. Runtime type errors need this, as do, for example these errors:

  • "Lists::ListButFirst3",
    • bf [] => ERROR BF got an empty list as input.
  • "Lists::ListButLast3",
    • bl [] => ERROR BL got an empty list as input.
  • "Strings::StrButFirst2",
    • bf "" => ERROR bf got an empty string as input.
  • "Strings::StrButLast2",
    • bl "" => ERROR bl got an empty string as input.

Since much work has been done on Tortoise/master since this was worked on, there will surely be new tests and prims that will need to be fixed, too.
