The BNF Converter (bnfc) is a wizard generating syntax trees, parser and printer from a Labelled BNF (LBNF) grammar. It is currently able to generate Haskell, Agda, C, C++, Java, and OCaml representations. Supported parser generators: Happy, ocamlyacc, Menhir, ANTLR, CUP, Bison. More information: http://bnfc.digitalgrammars.com Changes in 2.9.4: - LBNF: empty tokens types are now forbidden [#388] - Agda: support position information via --functor [#405] - C/C++: use size_t and -Wsign-conversion [#391] - C++: repair broken --line-numbers [#390], regression in 2.9.2 by [#349] - Haskell: fix a problem with layout stop words and top-level layout [#399,#413] - Haskell: generated test parser can parse several files now [#400] - Java: use L.valueOf() instead of deprecated new L() for literal classes L [#402] - Ocaml: non-terminals in generated parser are now type-annotated [#407] - Ocaml: sanitize bound variables in define - Ocaml/Menhir: update parse error mechanism to Menhir 2021/12/30 [#414] Cheers, Andreas -- Andreas Abel <>< Du bist der geliebte Mensch.

I’m pleased to announce the initial release of fresnel, an optics library optimizing for few dependencies, familiar tools, and decent error messages, without sacrificing functionality. fresnel is available at: - https://hackage.haskell.org/package/fresnel-0.0.0.0 - https://github.com/fresnel/fresnel/releases/tag/0.0.0.0 Feature requests, issues, and other feedback are welcome at https://github.com/fresnel/fresnel/issues Overview: - Most of the optic types from lens and optics. No Indexed*, however. - Compose optics using . much like in lens. - Decent error messages, much like in optics. - Few dependencies. I’m considering pulling At/Ixed into a new package to reduce the dependency list that much more, out of a desire to “pay for what you use.” I’m considering divesting the package of the profunctors dependency for much the same reason. - Named for a real-world optic which has saved countless lives by its use in lighthouses around the world. Best regards, Rob
