Details:
Please provide a function that users and third-party packages can rely on
inside of Octave to get the suffix / file extension for executable programs.
For example, on Unix and GNU/Linux operating systems this would return the
empty string, and on Windows this would return '.exe'.
Inside of Octave, m-file functions use
ext = __octave_config_info__ ("EXEEXT");
This works fine for Octave itself, but is not a function that should be relied
on for code outside of Octave. So Octave should provide an equivalent that can
be used safely.
As a motivating example, the Octave Forge package 'miscellaneous' shells out
to the program 'units'. It has a check that the executable 'units' exists in
PATH, but it has to append EXEEXT to ensure that it works on Windows.
function fpath = check_units ()
## See bug #38270 about why we're checking this way.
fpath = file_in_path (getenv ("PATH"), sprintf ("units%s",
octave_config_info ("EXEEXT")));
if (isempty (fpath))
error ("units: %s\nVerify that GNU units is installed in the current
path.",
rawoutput);
endif
endfunction
