Display source code of code tiddlers

I’ve just read about $:/core/ui/ViewTemplate/body/code and have tied this in a tiddler:

<$tiddler tiddler={{!!target}}><$transclude tiddler="$:/core/ui/ViewTemplate/body/code"/></$tiddler>

This will display the code of the tiddler identified by the //target// field. Fine

There’s not much in $:/core/ui/ViewTemplate/body/code, I would generally use the <$codeblock> widget directly:

<$codeblock code={{{ [<currentTiddler>get[text]] }}} language={{{ [<currentTiddler>get[type]else[text/vnd.tiddlywiki]] }}}/>

@jypre

if the target is a tw5 tiddler, its code is shown but without syntax coloration. Is there a way to have this feature enabled?

There should be syntax highlighting if you have the Highlight plugin installed. Note that many content types (notably wikitext) used in TiddlyWiki are not recognised by the plugin, and so won’t have syntax highlighting applied.

@jypre

if the target tiddler had a //code// tag, could there be a way that, by itself, this tiddler would be displayed as code and yet interpreted as usual when transcluded?

We already support setting the code-body field to yes to force a tiddler to be displayed in the story river as code but transcluded as normal. Is there a reason you’d prefer a tag?

In any event, the following filter would achieve what you want:

[tag[code]then[$:/core/ui/ViewTemplate/body/code]]

It would need to be put in a tiddler tagged $:/tags/ViewTemplateBodyFilter with a blank list-before field to force it to the top of the cascade.
