Redcloth upwards - Jan 2007 - Strikethroughs and dashes

Who really uses strikethroughs??  This is one of the most common
tripwires in RedCloth.

  You are the friend--the only friend--who has offered to help.

Obviously em dashes.

  I died in -2006- wait, no, two-thousand-FIVE!

Obviously strikethrough.

  I''m going on a trip - a long one - to the Virgin Islands.

That''s got to be en dashes.

  Such a cheap, no-hassle, no-worry guarantee!!

Hyphens, but can be confusing to parsers.

All but the first work with Trad. RedCloth.  Have you encountered other
sticky scenarios I can add to the tests?  Maybe I can scale back the
strikethroughs in SuperRC?

_why

> Maybe I can scale back the strikethroughs in SuperRC?
That would be great!  I''ve seen many people get hung up with em-dash- 
laden sentences.  The more advertising background they have, the  
worse they are with this. :-)

Okay, in SuperRedCloth:

  space dash words+ dash space

Strict just like that!!

You can can have spaces and some punctuation between words, but the
dashes must be up against the first and last words of the phrase.

It still smells, though.  What if you have to strike-out something
with dashes in it??  I guess it''s back to <del>..</del>.

There should be a syntax for grouping text.

  I died in -(two thousand six -- yes i did -- fell off a cliff)-
  -- no, wait, I died in 2005 while jogging...

Who knows.

Hmm, is that sufficient?
irb(main):006:0> str = " what - will - this - do?"
=> " what - will - this - do?"
irb(main):007:0> str =~ regexp
=> nil

No, I haven''t prised the lid off to see if this uses regexps
or a Proper parser.

I don''t know enough about Super Red Cloth to add anything useful,
except that if it makes it easier to maintain, that is good.  I''m
not clear about how Ragel fits into the picture yet, whether we
need to install that as well to get it to work or what.

One sticky scenario we get a lot in our application is people putting two
smilies somewhere in their post.

Here is a smilie :-) And another :-( Bugger!

Comes out with a strikethrough... Undesired!

Definitions are already a part of RedCloth 3.  I''m not sure who
introduced them or when, but...

  - Foo :  definition
  - Bar := definition

Some Textile hacks use:

  @ Foo ~ definition
  @ Bar ~ definition

Textil.pm is:

  dl. Foo:definition
  Bar:definition
  
I think I like the WikiCode syntax better.  I''m open to this in
SuperRC, let''s just be sure to allow styling and alignment as with
the other elements.

  ;(highlight) Foo : definition
  ;{color:red} Bar : definition

Also, PyTextile and Textile v2 should be checked for a precedent
perhaps.

Not quite.  The definition of "words" isn''t (.*). 
It''s a bit more
complicated!!

That''s correct.  Dashes are found up against the "2048" and
"dogfood", so that would be a strike.

But you bring up yet another great ambiguity: negative numbers!!

That''s also correct.  Those dashes are en dashes.  There''s no
question there.

You won''t need to install Ragel unless you''re compiling from
the
repo.  The tarball and gem dists will be premade for ya.  See
Hpricot and Mongrel -- same thing.

Oh, yes.  That''s a good one.

SuperRC does:

  <p>Here is a smilie :&#8211;) And another :&#8211;(
Bugger!</p>

While RedCloth 3 does:

  <p>Here is a smilie :<del>) And another :</del>(
Bugger!</p>

So, progress.

_why

Is there a spec for textile? Is redcloth supposed to conform to a spec?

I am concerned that we are seeing the development of several incompatible
dialects of textile.

It''s an informal sort of thing.  I mean the reference[1] is very basic,
giving plenty of room for interpretation.

Like: type a few long-nosed smilies into that page.  There''s no
science to the dwimmyness of it.

um...doesn''t work for me.

rico:~ murphy$ gem list redcloth

RedCloth (3.0.4)

rico:~ murphy$ redcloth
- foo := bar
<p>- foo := bar</p>


am I wrong?
[murphy]

It is in svn trunk, not 3.0.4

:-) This was just to get the ends about right as a first
shot.

New dimensions in temporal physics... :-)  Good point though, I
hadn''t thought of that.  How to strikeout a negative number?
           -\-2048 -- That was way back in negative
time!-

Thanks. (OT: Is it pronounced more like Rigel or Bagel, soft or hard
g?)
