When calling the pretty printer method pp-LangName-string (from the generated pp.str) the transform fails with stack a trace. This is in a file using embedded syntax in the transform rules. here is an example:

<debug> ("some debug message: ", <pp-Booster2-string> x)

We tried both ctree and jar builds, the issue still occurs. Below is a sample stack trace. Without the call the transformation worked fine.

This is either a bug in the pretty-printer, or you're feeding an incorrect term to the pretty printer. Make sure your term conforms to the signatures, otherwise the pretty-printer does not work.


On 5 July 2016 at 13:16 Seyyed Shah commented:

Ah ok, thanks for the feedback. the terms should be valid as they are passed back to us when no strategy matches in one of our transforms. Has the behaviour of the pretty-printer changed when given term fragments?


On 18 July 2016 at 14:18 Gabriël Konat commented:

If you pass partial fragments to the pretty-printer, make sure to use the pp-<LanguageName> strategy, or pp-<Sort> where Sort is the sort of the partial fragment. Otherwise, pretty-printing will fail.
