* module/language/ghil.scm (unparse-ghil): Fix unparsing of quasiquoted expressions. * module/language/ghil/spec.scm (join): Define a joiner for GHIL. * module/language/scheme/compile-ghil.scm (cenv-ghil-env): Expand the definition of a CENV so it can have an actual ghil-env, if available. (compile-ghil): Return the actual ghil env in the cenv. * module/system/base/compile.scm (compile-file): Rewrite. `output-file' is now a keyword argument, along with the new kwargs `env' and `from'. We now allow exceptions to propagate up, and instead of printing the output file to the console, we return a string corresponding to its location. (compile-and-load): Use read-and-compile. (compile-fold): Thread around the cenv as well. Return all three values. (find-language-joint, read-and-compile): New exciting helpers. The idea is that compiling a file should be semantically equivalent to compiling each expression in it, one by one. Compilation can have side effects, e.g. affecting the current language or the current reader. So what we do is find a point in the compilation path at which different expressions of a given language can be joined into one. Expressions from the source language are compiled to the joint language, then joined and compiled to the target. (compile): Just return the first value from compile-fold. * module/system/base/language.scm (language-joiner): New optional field. * scripts/compile: Rework for changes to compile-file. |
