[Ocaml-lib-devel] OptParse.OptParser.make and usage string

[Janne H. <ja...@hy...>]

Hello,

I believe I have found a bug in function OptParse.OptParser.make.  The
documentation states that "Any occurrence of the substring "%prog" in
usage is replaced with the name of the program".  This suggests that
all occurrences of that string are replaced.

This is not the case: the substitution of %prog (unprogify in
optParse.ml) uses ExtString.String.replace internally, which replaces
only the first matching %prog.

Has there been any discussion on providing examples on how to use
extlib?  I think using OptParse would be easier if there were some
simple example applications around.

Does there exist a regression test suite for extlib?

Btw: I upgraded the GODI package for extlib to use the new 1.3
version yesterday.

Best regards,
