Constants
| Name |
|
Description |
| A_PROTECT |
= 004 |
We work by substituting non-printing characters in to the text. For now
I‘m assuming that I can substitute a character in the range 0..8 for
a 7 bit character without damaging the encoded string, but this might be
optimistic
|
| HTML_TAGS |
= {} |
This maps HTML tags to the corresponding attribute char
|
| MATCHING_WORD_PAIRS |
= {} |
This maps delimiters that occur around words (such as bold or
tt) where the start and end delimiters and the same. This lets us
optimize the regexp
|
| NULL |
= "\000".freeze |
|
| PROTECTABLE |
= [ "<" << "\\" ] |
A \ in front of a character that would normally be processed turns off
processing. We do this by turning < into <#{PROTECT}
|
| PROTECT_ATTR |
= A_PROTECT.chr |
|
| SPECIAL |
= {} |
And this maps special sequences to a name. A special sequence is
something like a WikiWord
|
| WORD_PAIR_MAP |
= {} |
And this is used when the delimiters aren‘t the same. In this case
the hash maps a pattern to the attribute character
