#938 assigned enhancement

Feature Request: Load type files for units

Reported by: megane Owned by: felix
Priority: minor Milestone: 5.1
Component: compiler Version: 4.8.x
Keywords: types units Cc:
Estimated difficulty: medium


Currently type files for units not installed in the repository are not loaded.

I've attached a patch that does something like this, but it's just a quick hack that works for my needs.

You should probably use ##sys#resolve-include-filename to find the types file, like it's used to find the inline files.

  • Milestone changed from someday to 5.1

Seems to be somehow related to the new unit/module handling in 5.0

I think this issue was me confusing -I as an option to define additional paths CHICKEN should use to look for modules, when it's actually for the include form only.

CHICKEN only looks for modules in the egg repository and current directory. For modules in the current directory it does not automatically import .types or .inline files. You have to use -consult-types-file and -consult-inline-file for those, respectively.

Maybe the -I could be made to specify additional paths to consult modules from, if that makes sense.
I'm OK if this issue is closed as invalid, though.

The following shows that .types files are not automatically loaded.

$ ./
 (chicken-5 (import (chicken base))
            (import mod))
 (else (import chicken)
       (use mod)))

(print "--- main ---")
(compiler-typecase (foo 1)
  (symbol (print 'ok))
  (* (error "was not symbol")))
 (import scheme)
  (chicken-5 (import (chicken base) (chicken type)))
  (else (import chicken)))

 (: foo (* -> symbol))
 (define (foo x)
   (if (fixnum? x)
#!/usr/bin/env bash
set -e
set -o pipefail
