digitalmars.D.announce - Drat! A packrat parser!

Hi,

I'm working on a packrat parser library called "Drat!".

The current version (pre-alpha) v.0.1 can be found here:

   http://wiki.dprogramming.com/Drat/HomePage

So now you cry "We have loads of parser generators already!"?

Here goes:

  * Ever wanted to be able to use &!?*+ not only in regular
    expressions, but in your *parsing_rules*?
    With Drat! you can!

  * Sick of unreadable generated parser code?
    Drat! is a library, it needs *no* code generation step!

  * Do you want to be able to understand the parser you use?
    Not all in Drat! is trivial, but you have a sporting chance!

  * Do you want your parser to be fast and linear in time?
    Drat! is!

The current (temporary) drawbacks of Drat! are:

  * Documentation is *very* sparse right now, but the example
    programme is lavishly commented.

  * No user error messages when parsing fails.

  * You *want* a code generator? Make a request! :)

Regards,

   frank / 0ffh

I have a couple suggestions:

1) The description in the newsgroup posting is much better than the one 
on the web page.

2) The phrase "D programming language" should appear on the web page, so 
google can find it.

Fixed and fixed, with [Ctrl]-[C] + [Ctrl]-[V] ... the power of copying! ;-)

And if we are going to be picky, can you increase the contrast between the
background and text please.

Sorry, no can do - it's a Wiki, and I doubt I can hack it's style sheets.
Anyways, on my screen it's black on light gray - where's the trouble?

Can you ask the wiki's admin?

It's black on (not-so-)light gray.

The background colour is #D1D1D1 and with a small font on a 19-inch monitor
the edges of the text become indistinct. I changed the font to a non-serif
one and that helped but the best combination was a non-serif font and a
background colour of at least #F0F0F0. 

(Of course, this could be just my aging eyes)

Chris[], it's for you! =)

Hehe, I have quite bad eyes, that's why I use Opera. It has an excellent
zooming function (altough Firebird may be getting there, in time)!

I can read it ok, but dprogramming.com always makes me feel depressed 
when I go there because of that heavy gray background.

Yeh, definitely an improvement.  Especially the little happy sun in the 
corner.  :-)

Very nice indeed.

Now that it's different, I admit it may have been a bit on
the sombre side before.. thanks, it looks much better now!
Suddenly I feel so strangely... cheerful... Drat! =)
