PSPP-BUG: [bug #23182] Changing the command line interface of PSPPire

[John Darrington]

Update of bug #23182 (project pspp):

                Severity:             5 - Average => 1 - Wishlist           
                 Release:                    None => Post-0.6.0

Follow-up Comment #1:

I think that the issue of command line argument processing needs to be one of
the first considerations after the forthcoming release.

Some of the questions to be considered are:

* Which command line options need to be common between pspp and psppire ? 
The common ones should have a common parsing subroutine.

* How should psppire know what to do with a filename given as an argument? 
It has to decide whether to open it as a system file, portable file or syntax
file.  Can we rely on the filename suffix?

* It would be useful to be able to give a syntax fragment as a string on the
command line.

* We need to make sure that we get the syntax of the command line right, as
subsequent changes in later versions causes pain for users.
