The nowiki and preformatted markup syntax doesn't let us quote actual markup for nowiki and preformatted -- this is especially needed when talking about the syntax or explaining it.
The nowiki and preformatted markup syntax doesn't let us quote actual markup for nowiki and preformatted themselves-- this is especially needed when talking about the syntax or explaining it. That's why there is a need to modify or extend the syntax, so that it is possible to include "{{{~}}}}}}" in them.
At line 3 changed one line
One possible solution is to include any trailing "}" into the nowiki or pre block, like this: {{{{{{foo~}}}~}}}}}} produces {{{<nowiki>foo~}}}</nowiki>}}}. This solution, however, only allows you to put the curly braces at the end of the block. While this is enough for our current use cases, it's not a general solution.
The solution chosen for nowiki is to include any trailing "}" into the nowiki span, so that this:

That's why it may be good to have a special markup, as an exception parsed inside the pre and nowiki blocks, that "escapes" the closing of these blocks. Even when it's just adding special cases, as now we can't possibly inslude *that* markup in a pre block.
{{{
{{{foo}}}}}}
}}}

Note, that -- as the escape is only valid inside the pre blocks, and then only before the actual end marker -- there is little chance for conflict.

----
!Tilde "~"
Advantages:
* Used on:
** JSPWiki
* Has semantic connotation wit "not", which might suggest the meaning when seen
Disadvantages:
* Not available on many [Keyboards]
* Hard to type under Microsoft Windows (Could you be more precise? I have no trouble typing it using MS Windows with a US or German keyboard)
* Traditionally used in text as an alternative to hyphen (eg. in number ranges) or meaning "roughly".
----
!Backslash "\"
Advantages:
* Extremely widespread for escaping in:
** Programming languages
** File names
** Regular expressions and search queries
Disadvantages:
* Used in Microsoft Windows for paths
* A bit confusing considering the double backslash proposed in Creole 0.4.
----
!Caret "^"
Advantages:
* Sometimes used to mean "not"
Disadvantages:
* Not on all [Keyboards]
* No precedent (?)
----
!Percent "%"
Advantages:
* Commonly used for an alternate escape character, when backslash is not available
** for printf parameters
** for time and date formatting
** for colored text
Disadvantages:
----
{{{
<nowiki>foo}}}</nowiki>
}}}
The preformatted markup syntax requires some kind of an escaping mechanism. Fortunately, the escaping is only necessary when there is "{{{~}}}}}}" at the beginning of a line present in the block. In this case, to avoid treating the braces as markup for the end of the block, it needs to be indented with a single space. Furthermore, any line consisting of only indented three closing curly braces will have one space removed from the indentation -- to allow representing any possible text inside the preformatted block.
So, for example, this markup:
{{{
int main(int argc, char *argv[]) {
if argc>0 {
if argc<=1 {
--argc;
}}}
}}}
will produce this result:
{{{
<pre>
int main(int argc, char *argv[]) {
if argc>0 {
if argc<=1 {
--argc;
~}}}
}}}
