Works all one one line..
/**
*
* Some ignored comments here...
* @config { name:'Orange Title (70pt)'}
*/
h1.title_orange {
}
Works on multiple lines, with extra lines in comment
/**
*
* Some ignored comments here...
* @config {
name:'Green Title (70pt)',
order:1
}
*/
div.green_title {
}
Workson multiple lines, with extra lines in comment
/**
* @config { name:'Blue Title (70pt)',
order:1 }
* comments coud be here
*
*/
span.blue {
}
THis doesnt work due to the mutliple classes..... Not sure what im going to do with this yet, probably just match the first one - I suppose we could have multiple @config attributes matched in order to the definitions, but that sounds very hard....
