Parse template parameters to DOM or other non-wikitext types where possible
Closed, ResolvedPublic

Description

To do this, we will need knowledge of which template parameters can be parsed to DOM or other types and which need to remain wikitext. A start tag parameter should probably not be parsed to DOM for example (as a passed-in start tag would be balanced in the process), while most content parameters can. Apart from wikitext string vs. DOM we could also eventually refine parsing further for things like dates, numbers etc. Our DOM spec for templates [1] is already prepared to represent DOM and other representations of individual parameters.

The main thing that we'll need for the next step is information on where it is safe to do so. This information can come from something like TemplateData or DBPedia.

My current patch (WIP at https://gerrit.wikimedia.org/r/#/c/110381/ ) crashes on parser test "Templates: Indent-Pre: 1e. Wrapping should be based on expanded content" when testing "{{echo|{{echo| }}bar}}", although the same wt works when using parse.js.

This has been merged into master, but it's not enabled by default. To test it out, add

parsoidConfig.addHTMLTemplateParameters = true;

to localsettings.js, or use the option --addHTMLTemplateParameters=true with command line tools.

Current status: This is not yet enabled in production while we are investigating the performance impact.
