# Definitions related to run-time type checking. Used in particular

Convert libs to a fixed-point This does break the API of being able to import any lib file and get its libs, however I'm not sure people did this. I made this while exploring being able to swap out docFn with a stub in #2305, to avoid functor performance problems. I don't know if that is going to move forward (or if it is a problem or not,) but after doing all this work figured I'd put it up anyway :) Two notable advantages to this approach: 1. when a lib inherits another lib's functions, it doesn't automatically get put in to the scope of lib 2. when a lib implements a new obscure functions, it doesn't automatically get put in to the scope of lib Using the test script (later in this commit) I got the following diff on the API: + diff master fixed-lib 11764a11765,11766 > .types.defaultFunctor > .types.defaultTypeMerge 11774a11777,11778 > .types.isOptionType > .types.isType 11781a11786 > .types.mkOptionType 11788a11794 > .types.setType 11795a11802 > .types.types This means that this commit _adds_ to the API, however I can't find a way to fix these last remaining discrepancies. At least none are _removed_.

lib/types: Set name of types.package to "package" Nobody seems to have noticed this (except @Profpatsch) that options with a "package" type do not get included in the manual. So debugging this was a bit more involving because while generating the manual there is an optionList' attribute built from the collected attributes of all the option declarations. Up to that point everything is fine except if it comes to builtins.toXML, where attributes with { type = "derivation" } won't get included, for example see here: nix-repl> builtins.toXML { type = "derivation"; foo = "bar"; } "<?xml version='1.0' encoding='utf-8'?>\n<expr>\n <derivation> <repeated />\n </derivation>\n</expr>\n" nix-repl> builtins.toXML { type = "somethingelse"; foo = "bar"; } "<?xml version='1.0' encoding='utf-8'?>\n<expr>\n <attrs> <attr name=\"foo\">\n <string value=\"bar\" />\n </attr> <attr name=\"type\">\n <string value=\"somethingelse\" /> </attr>\n </attrs>\n</expr>\n" The following function in libexpr/eval.cc (Nix) is responsible for toXML dropping the attributes: bool EvalState::isDerivation(Value & v) { if (v.type != tAttrs) return false; Bindings::iterator i = v.attrs->find(sType); if (i == v.attrs->end()) return false; forceValue(*i->value); if (i->value->type != tString) return false; return strcmp(i->value->string.s, "derivation") == 0; } So I've renamed this now to "package" which is not only more consistent with the option type but also shouldn't cause similar issues anymore. Tested this on base of b60ceea, because building the dependencies on recent libc/staging changes on master took too long.

Convert libs to a fixed-point This does break the API of being able to import any lib file and get its libs, however I'm not sure people did this. I made this while exploring being able to swap out docFn with a stub in #2305, to avoid functor performance problems.
