Starter project: getopt_long in Ada

[Natasha Kerensikova <lithiumcat@gmail.com>]

Hello,

I have been tinkering with Ada for a while now, and I'm starting to feel
ready to write code that is (somewhat) useful, and to publish it.

I'm starting with a pure-Ada implementation of a getopt_long-like
command line argument processor. The motivation is that next project
will like have a command-line interface (before I go into other fancy
I/O), and I like having long option names, especially in scripts I'm
likely to re-read in the future. While I have found a few
implementations of getopt, for getopt_long I have only found binding to
the C function, which involves C strings and C arrays.

So I wrote a Getopt_Long package, along with a test suite, that can be
found at:
http://fossil.instinctive.eu/natools/dir?ci=tip
(I went against fossil advice of requiring going through a CAPTCHA
before reading the files, it might change in the future if non-human
hits do strain the server.)

Everything is under ISC licence, so anybody can re-use it, even though
it's currently still very young and under development.

I would gladly welcome any constructive comment about this code, whether
it's on the design, the implementation, the style, or anything else. The
only reason for publishing it at this point is to ask for feedback in
order to progress. I'm aware that a code review is a lot to ask, but I
would really welcome any help towards improving my mastery of Ada.


Thanks in advance for your comments and your help,
Natasha
