Description Peter Cherepanov 2020-12-07 22:12:37 UTC

The two-level nature of command line argument processing makes full validation of command line arguments quite difficult to implement. However a partial solution is better than nothing.

Let's add a new options, for instance, -D that checks whether the name is present in a whitelist and rejects the rest.

Comment 1 Ray Johnston 2020-12-08 16:25:28 UTC

-D is already used -- it is a synonym for -d

This kind of thing might be part of our documentation improvement effort.

The importance of command line argument validation is sort of waning as the
use of Ghostscript (and GhostPDL) shifts to the newer API functions such as
gsapi_set_param using the JavaScript, Java, python, or C# bindings.
