* Basic grammar and parser for the Fix language. We use libsglr and friends to do the parsing. The parse table is embedded in the Fix executable using bin2c, which converts an arbitrary file into a C character array. 2003-10-29 16:05:03 +00:00			`#ifndef __PARSER_H`

* Maintain integrity of the substitute and successor mappings when deleting a path in the store. * Allow absolute paths in Nix expressions. * Get nix-prefetch-url to work again. * Various other fixes. 2003-11-22 18:45:56 +00:00			/* Parse a Nix expression from the specified file. If `path' refers

* Clean up the imploded parse tree. Quotes around strings are removed, paths are absolutised relative to the path containing the expression we just parsed, and integer literals are converted to actual integers. 2003-10-30 16:18:40 +00:00			`Expr parseExprFromFile(Path path);`
