Eric, thank you for showing what I've missed about macros, that is
important for me! I will use that with any variable/macros used only in the
Story River.
But in this case and on the present time links are to be refreshed
everywhere including the Sidebar.
Here is my custom piece of link.js. Later i'll optimize it, as it is my
first touch of JavaScript, styles, etc..
if(!this.isMissing && !this.isShadow) {
var toTiddler = self.wiki.getTiddler(self.to),
toFreq = Number(toTiddler.getFieldString("freq")),
toWeight = Number(toTiddler.getFieldString("weight")),
highlightGain =
Number(this.getVariable("hb-highlight-intensity-kw"));
if (toWeight || toFreq) {
domNode.setAttribute("style","font-weight:"+(highlightGain*4.99*(toFreq)+400-200*highlightGain)+";
background:rgba("+(150+toWeight)+","+(250-toWeight)+",235,"+
(highlightGain*(toFreq/(150)+0.5)) + "); text-decoration: none; color:
inherit;border-color: rgba("+(155+toWeight)+","+(255-toWeight)+",255,"+
(highlightGain*(toFreq/(150)+0.5)) + "); border-radius: 4px;
border-bottom-width: 0px; border-left-width: 2px; border-right-width: 2px;
border-top-width: 0px; padding-inline-end: 1px; padding-inline-start:
1px;border-style: solid");
domNode.setAttribute("data-toWeight",toWeight);
} }
