Collapsible Tokens

Hi Markus,

The outlining mechanism of SyntaxEditor is pretty open-ended so really it can support outlining for anything.

If you are using a dynamic language, then the default outlining mechanism (where we do the hard work of updating the outlining) does outlining based on various token pairs. Like for C# it looks for { and } tokens. There are several samples of that in the sample project in the dynamic language code-behind files.

For languages where you do more advanced parsing and create ASTs, we have a mechanism like in the Simple language sample that takes the AST and can build outlining nodes from that.

The final option is to write your own outlining mechanism by calling the various methods on our Outlining class however I will warn you, it's pretty tricky to do it right. So that's why I would recommend one of the two above approaches instead.

Hello,

yes I have seen the possibilities of the outlining, but I am wondering (or needing) the possibility to collapse tokens in the middle of a line, not like in the examples of c#.

an example would be;

collapsed
if (|+|value = true) {

}

expanded
if (|-|tree/temp/value = true) {

}

Thanks
Markus Alexander

Well the outlining node toggle boxes must appear in the margin area, not within text flow. If you mean you want the +/- where you indicate in your code example, that isn't possible.

However any outlining node can cover characters on a single line if that is what you are asking. By that I mean outlining nodes don't have to span more than one line.
