Hi all,

There is an exciting new release of Gerbil, as we now support the #lang form for custom language preludes with arbitrary syntax. The release also comes with an extensive parsing/lexing library, so that you can easily write new language grammars in declarative syntax.

Custom languages are documented in the Guide and the Custom Languages tutorial: https://github.com/vyzo/gerbil/blob/master/doc/tutorial/lang.md
