Custom language in Chez Scheme

[Michał Pociecha-Łoś]

I'm using Chez Scheme to implement a new language with non-scheme syntax, and I'd like to configure Scheme to use a different `read` procedure when loading a code in that language. It does not seem to be possible at this moment.

What would work for me is a special thread parameter, which would allow me to pick a custom `read` procedure based on file extension. Is it possible to implement such behaviour in Chez Scheme?

Best,

Michał

read is for reading scheme data (i.e., s-expressions plus the extensions that chez scheme has added to reader syntax).  load is for loading scheme files.  If you want to implement a new language then don't use those.

For an interpreter for a new language, just define different functions (or define your own versions with those names that work however you want).

If you are asking about how to implement a compiler for a new language and want to integrate with all of Chez Scheme's fancy automatic compilation on import, etc., then you want the compile-library-handler and compile-program-handler thread parameters.
