Yesterday I finally got down to it and made a few additions to the
customFormat formatter, specifically the class ("{{") case.
- Very often I will want to have a div with a class and an ID, and the
only way I know to do it by default is to use the HTML tag, which means I
can't use markup.
- I changed the lookahead regex in the "{{" select case to recognize
periods and pound signs as well. Before it only recognized spaces and
letters.
- Before (I just now discovered) multiple classes could be included by
adding spaces. I don't know if that takes away some of the need for this as
core functionality. This is also retained as default.
- The default behaviour is retained, and since my code only changes the
handler, not the match regex, it shouldn't change what markup gets snagged.
- Currently if periods or pound signs are included the result looks like
this: .hi.there{hi too}}} I don't think that is considered correct
functionality, but rather a syntax error.
- The one change to the default behaviour is the addition of a null
(HTML: no '="") id attribute in Chrome. I haven't checked Firefox. I don't
know if this matters or not.
- Once I've thought about it some more, I'm not sure if this is even
needed since you can include more than one class, which as I said I just
discovered. But, oh well, here it is in case anyone wants it.
So, without further ado, here is the code -- as a plugin.
--Arlen
for (var i = 0; i < config.formatters.length; i++){
if(config.formatters[i].name == "customFormat"){ //look for the
customFormat formatter.
config.formatters[i].handler = function(w)
{
switch(w.matchText) {
case "@@":
var e = createTiddlyElement(w.output,"span");
var styles = config.formatterHelpers.inlineCssHelper(w);
if(styles.length == 0)
e.className = "marked";
else
config.formatterHelpers.applyCssHelper(e,styles);
w.subWikifyTerm(e,/(@@)/mg);
break;
case "{{":
var lookaheadRegExp =
/\{\{[\s]*([#\.\w]+[\s\w\.#]*)[\s]*\{(\n?)/mg; //changed this to
include . and #
lookaheadRegExp.lastIndex = w.matchStart;
var lookaheadMatch = lookaheadRegExp.exec(w.source);
if(lookaheadMatch) {
w.nextMatch = lookaheadRegExp.lastIndex;
var lam = String(lookaheadMatch[1]);
var cl = "";
var id = "";
if(lam.indexOf('.') != -1 || lam.indexOf('#') != -1){
//lam = lam.replace(/ /g, "");
var i = lam.length;
var cur = "";
while (i--) {
if (lam[i] == '.' && cur.length > 0) {
cl = cl + " " + cur
cur = "";
} else if (lam[i] == '#' && cur.length > 0) {
id = id + " " + cur;
cur = "";
} else if ((lam[i] == '#' || lam[i] == '.') &&
cur.length == 0) {
continue;
} else cur = lam[i] + cur;
}
if(id == "" && cl == "") cl = lam; //this shouldn't get hit
} else cl = lam;
//the trim removes extra spaces from the beginning and end
e = createTiddlyElement(w.output,lookaheadMatch[2] == "\n"
? "div" : "span",id.trim(),cl.trim());
w.subWikifyTerm(e,/(\}\}\})/mg);
}
break;
}
}
}
}
