This allows us to add a docstring to .append() so users can see
the names of the arguments that are being passed, and means we
don't have to remember to prepend run_ when calling a hook.
Still todo:
- Add separate module for GUI hooks
- Update the remaining runHook/runFilter() calls
- Document the changes, including defensive registration
- The front and back are rendered in one call now. If the front
side contains no custom filters, we can bake {{FrontSide}} into the
rear side. If it did contain custom filters, we return the partially
complete rear template instead, and the calling code can inject
the FrontSide in after it has been fully rendered.
- Instead of modifying "cloze" into something like "cq-2", the card
ordinal and whether we're rendering the question or answer are now
passed in to the rendering filters as context.
- The Rust code doesn't need to support filter names split on '-'
anymore.
- Drop the "Show" part of hint descriptions so i18n support can be
deferred.
- Ignore blank filter names caused by user using two colons instead
of one.
- Fixed hint field and text transposition.
This extends the existing Rust code to handle conditional
replacement. The replacement of field names and filters to text
remains in Python, so that add-ons can still define their own
field modifiers.
The code is currently running the old Pystache rendering and the
new implementation in parallel, and will print a message to the
console if they don't match. If you notice any problems, please
let me know.
In the process of factoring out the field filtering, the "extra"
and "fullname" args are just passed in as a blank string now.
Extra was functionality that allowed a field modifier to be defined
as "filtername(arg1,arg2):field", and fullname was the name of the
field including any provided field modifiers. From grepping through
the add-ons on AnkiWeb, neither appears to have been used.
