Well, you're being too clever! You (no, I don't really mean you, the
OCaml developer, I mean "you" the generic user) are not supposed to know
bantam.bin even exists; you're just supposed to run 'bantam', which is a
shell script.
The cause of that exception is
Sys.getenv("BANTAM_USER_DIR")
That variable is set by the 'bantam' shell script to its default value,
$HOME/.bantam; or you can override it by setting the variable manually
(BTW, the shell script also creates the $BANTAM_USER_DIR if it doesn't
exist).
Now, I agree this is a problem. I suppose that exception should be
handled, and maybe there's a need for better documentation. I'm not
really sure of the best way to deal with this, but one of my objectives
was to be able to produce an easily installed, relocatable binary. And
there needs to be a per-user directory for configuration, helper
scripts, and trash. The shell script is a bit of a kludge, but I don't
see another way to do it without either (a) eliminating flexibility in
installation or (b) limiting the audience for the program to OCaml
developers. I'm open to suggestions.
I appreciate the feedback. I'll add an exception handler in the next
version. Meanwhile, see what happens if you just run 'bantam.'
Best regards,
Matt
