I created a collection, then used raco to install it.
Ran into a problem where a test function within module X in the collection
accesses a file in the same directory as the source code:
(define (fun-timed-test-2)
(define ip (open-input-file "realtime-test-data.rkt"))
(match-define (list completed result) (fun-timed 2 (λ(e#) (read-line ip))))
(close-input-port ip)
(and completed (string=? result "#|"))
)
Now when this is run:
<pkgs>/liquid-lib/liquid/realtime> (fun-timed-test-2)
; open-input-file: cannot open input file
; path: /home/deep/liquid-lib/examples/keyword-ap/realtime-test-data.rkt
; system error: No such file or directory; errno=2
; [,bt for context]
The test data file is there in the same directory with the module (in
../realtime/), but racket is looking for the file in the directory the function
is being invoked from (../examples/keyword-ap/).
I've gone through the documentation, and the collects path doesn't help,
because this was a directory install, so the catalog is pointing to the
original source directory. There is a function (get-module-path) but I'm not
sure that is doing what I want, or at least I don't know the correct
incantation to make it go at it isn't giving me the path back from
(get-module-path X).
Will someone please share the incantation for getting the path to the data
file, or otherwise opening it?
