s:put
~~~
### Support Code
The first couple of words are a variation of `s:put` that
generates HTML codes for specific characters. This ensures
that code output displays correctly.
~~~
:c:put
$< [ '< s:put ] case
$> [ '> s:put ] case
$& [ '& s:put ] case
ASCII:SPACE [ ' s:put ] case
c:put ;
:s:put [ c:put ] s:for-each ;
~~~
For regular text, there are a couple of inline formatting things
to deal with.
These are:
* emphasis
* strong (bold)
* escaped characters
* code
~~~
'Emphasis var
'Strong var
'Escape var
'Code var
~~~

*Headers*
After this, I define detection and formatting of headers. The
headers should look like:
# Level 1
## Level 2
### Level 3
~~~
:header?
dup [ '#_ s:begins-with? ]
[ '##_ s:begins-with? ]
[ '###_ s:begins-with? ] tri or or
over '####_ s:begins-with? or ;
:format:head
ASCII:SPACE s:split
'# [ '
' s:put nl ;
~~~
*Horizontal Rules*
Horizonal rules consist of four or more - characters on
a line. E.g.,
----
--------
This also accepts sequences of `-+-+` which were used in
some older RETRO source files.
~~~
:rule?
dup [ '---- s:begins-with? ] [ '-+-+ s:begins-with? ] bi or ;
:format:rule drop '
s:put nl ;
:indented-list?
dup [ '__-_ s:begins-with? ] [ '__*_ s:begins-with? ] bi or ;
:format:indented-list
'
s:put nl ;
~~~
*Paragraphs*
Blank lines denote paragraph breaks.
~~~
:blank? dup s:length n:zero? ;
'InParagraph var
~~~
*The Formatter*
This ties together the various words above, generating the
output.

test-block? [ toggle-test ] if;
in-test-block? [ format:code ] if;
