VisualEditor: Transclusions editor should support parser functions and variables
Open, LowPublic


Parser function syntax is generally {{#function_name : expr1 | expr2 | expr3 | ...}}

Currently VE sees this as a template with name "#function_name : expr1" and arguments "1 = expr2", "2 = expr3", etc. This makes it impossible to edit expr1 in VE.

Same for parserfunctions like urlencode and template messages. The transclusions editor should be able to handle them, preferably by invisibly detecting them and failing that with a special, user-selected mode. Until we can, we should show an explanatory message when the user attempts to add one.

Yes, we need a special form of editing transclusions which aren't templates; I can't recall whether Parsoid gives us sufficient information to recognise these as different except for introspection.

Many of the parser functions are rarely used in the main namespace (#if, ...), but some of them are really important even in the main namespace. For example {{formatnum:...}} is probably used a lot there.

If Parsoid doesn't automatically tell VE whether something is a template or not, could it not be done by looking at the format of the string (e.g. {{# is never a template) or comparing it to a list of parser functions?
