Hello Sunday coders,
So I made a QuickScript to compile to standalone executable in a
platform-independent manner - without zipping. It works great, and Laurent
gave me a hand with the file browsing part for Linux. However I'm
encountering a hard to track runtime error with find-files. I am listing
all files with a certain extension. In the past I have used string-suffix?
for this, but I found out about path-has-extension? and attempted to use it
instead. I'm getting an error with both. Here's the code :
;; find files of a given extension recursively from the current directory
(define (find-files/ext path ext)
(define (ext-file? f)
(and (not (void? f))
(or (path? f) (string? f))
(file-exists? f)
(path-has-extension? f ext)))
(find-files ext-file? path))
The error I'm getting should not be possible. I have added all these checks
to try and catch it, to no avail:
[image: Capture.PNG]
;; same as previous, but using string-suffix?
(define (find-files/ext# path ext)
(define (ext-file? f)
(and (not (void? f))
(or (path? f) (string? f))
(file-exists? f)
(string-suffix? (path->string f) ext)))
(find-files ext-file? path))
When using string-suffix?, I'm getting a different error:
[image: Capture2.PNG]
I have used find-files many times over the years and I have never seen
this. The start-path is issued from (path-only f), where f is the source
file path given by QuickScript for the current source file.
If you're testing this code, note that when using path-has-extension?, the
icon file extension constants have to be prefixed with '#' to comply with
the function's param type.
Here's the full source :

Any help would be appreciated.
