I've added a link to Doxygen documentation of Nyctergatis engine interface to [[YvesPiguet]].
This will make it more difficult to retract now :-) If I opensource the engine, it should be under
the BSD license.
Answers to your questions:
# Java and Python, most probably. PHP, probably easy, maybe not very efficient because the engine doesn't rely on any library, so it goes down to low-level stuff such as folding CRLF sequences. Concerning Perl, based on my ancient experience, it would be possible, but I wouldn't like to do it myself... I think Perl is more suited to tasks where some of its built-in capabilities, such as regexp, can be exploited; that would require more work.
# My approach would be to compile the engine either as a standalone command-line application (as it's done now) and to call it from these languages, or maybe to compile it as an extension for these languages. Maintaining separate implementations in parallel would require much more work.
# Yes, I think so. Things which require lookahead over more than a few characters would be more difficult. The engine performs one pass, writing directly its output without intermediate storage of the document (just the state which includes nested lists and nested styles).
# Yes, very much. Output is completely factored out from parsing. It relies mainly on strings, with a few functions for character encoding, link encoding (URL), interwiki, etc, all optional.
I've added JSPWiki to the output formats supported by my sandbox...

Ok, my engine is now opensource, under the new BSD license. The
[[http://nyctergatis.com/creole/SimpleMarkup/html/|doxygen documentation]]
covers the whole source code, including the command-line application. I'll add a downloadable
archive very soon. Feedback welcome, of course.
-- [[YvesPiguet]], 2007-Mar-20
I've renamed the library "Nyctergatis Markup Engine" (NME), made its source code available in a downloadable
archive and rewritten the pages @nyctergatis.com. I hope I haven't broken anything.
-- [[YvesPiguet]], 2007-Mar-20
Just wanted to mention that I haven't forgotten NME, but plan to test it as soon as I have time.
-- [[SteffenSchramm]], 2007-Mar-28
No problem! I'll continue improving it, so you'd better download it right before taking a look.

//Discussion begun by email//
I am afraid, I find that the orderd/unordered list bug I reported earlier seems not to be fixed.
Rationale: When in list mode (ordered and unordered list) the parser interprets double {{{**}}} or {{{##}}} at the beginning of the next line as the beginning of a new list, when it should be just {{{<b>}}} or {{{<tt>}}}. It also writes empty {{{<b></b>}}} and places the contents before it (last example).
In my interpretation, this is not correct. I added two plain paragraph examples which show the correct behaviour, IMO.
Please find a few input and output examples below. I am using [[http://nyctergatis.com/creole/|NME-071004.zip]].
Here is the Creole code:
{{{
a b
##c##
a b
**c**
* ##a## b
##c##
# ##a## b
##c##
* ##a## b
**c**
# a
##b##
* a
**b**
}}}
My HTML output looks like this:
{{{
<!-- Generated by Nyctergatis Markup Engine, Oct 5 2007 19:27:19 -->
<html><body>
<p>a b <tt>c</tt></p>
<p>a b <b>c</b></p>
<ul>
<li><tt>a</tt> b</li>
<ol>

</ol>
</ul>
<ol>
<li><tt>a</tt> b</li>

</ol>
</ol>

</ul>
</ul>
</body></html>
}}}

It isn't a bug, imo, it's Creole specifications and implementation choices.
Nested lists are supported in Creole, so double-stars and double-sharps should
begin sublists when they're at the beginning of a line in a list. A design
choice which can be criticized is that item mark mismatches (such as {{{#}}}
following {{{*}}}, or {{{##}}} following *) are ignored. It's documented, though
("For clarity, list markers should be used in a consistent way; but only the
first item of each list fixes the kind of the whole list").
I've "fixed" the problem with {{{##}}} in readme.nme you mentionned in a previous
message by moving it so that it doesn't appear at the beginning of a line.
My error is a proof that my design choice leads too easily to ambiguities.
I'm probably going to change it.
Finally, concerning the empty {{{<b></b>}}}, it's caused by a trailing style marker
at the end of a paragraph (the first occurence of {{{**}}} is the sublist item marker).
Not really a problem, I think: it reflects accurately the source, even if it's
useless.
If you generate automatically Creole markup, a simple way to avoid the
ambiguities of {{{**}}} and {{{##}}} in lists is to avoid line breaks in lists items,
and in paragraphs for the sake of consistency. That's how we've converted
our help files for Sysquake from XML.

From my novice common sense understanding I believe that the following could make sense:
New list items of any kind ({{{*}}}, {{{**}}}, {{{#}}}, {{{##}}}) are only started if there is at least one white space chacter after the list characters (all list examples in the documentation also do it this way):
{{{
##text## -- <tt>text</tt>
**text** -- <b>text</b>
}}}
but
{{{
## text -- <ol><ol><li>text</li></ol></ol>
** text -- <ul><ul><li>text</li></ul></ul>
}}}
It would also solve the dilemma I reported previously, and it would also allow to start 2nd level nested cells with no prior 1st level nesting.
The rationale is that most list markers are white-space separated from the list in the final output. Because this is so common, I believe that it also makes the Wiki Syntax easier to read. And it there is not much sense in bold whitespace like {{{** text**}}} anyway (it would not be rendered by HTML for sure).
If I was to change the documentation, it would read like:
"List items begin with a {{{*}}} or a {{{#}}} at the beginning of a line. Whitespace is optional before the {{{*}}} or {{{#}}} characters, but at least one space is required to separate it from the item's text. A list item ends at the line which begins with a new list or sublist item (* or # character followed by a space), blank line, heading, table, or nowiki block; like paragraphs, it can span multiple lines and contain line breaks forced with {{{\\}}}."
I can see now why the {{{<b></b>}}} is there. But from a common sense persepective, I still believe it should not.

Your suggestion was already discussed here: [[Require Space After Bullet Proposal]]. It wasn't retained...
-- [[YvesPiguet]], 2007-Oct-6
In NME-071009, list markup must be consistent: in the example below, the first item spans two lines with //bar// displayed in monospace, and a one-item numbered sublist.
{{{
* foo
## bar
*# baz
}}}
