Ignore typst context contents with a filter: can it be done?

[alametti]

A typst source such as this cannot be converted to Pandoc AST:

#context {
  if target() == "html" {
    [HTML]
  } else {
    [Not HTML]
  }
}

Presumably this is because Pandoc attempts to evaluate the content of the context block:

Context e -> do
  evalExpr e -- TODO for now we just ignore "context"

This also occurs any time a context block attempts to call any unsupported built-in typst function.

Is there a way to write a filter to completely ignore the contents of a context block instead (similar to what is requested in the last comment of #9712)?

I'm not sure if this is possible since no AST is generated to filter upon:

$ pandoc -s -t native test.typ
"test.typ" (line 3, column 2):
Identifier "target" not found

If filtering isn't possible in this scenario, I'll try using pre-pandoc makefile directives instead.

No - the problem is in the parsing phase, and filters are applied after parsing succeeds.

Thanks! (and off-topic but pandoc.org/app is amazing, congrats to all contributors!)
