* handle explicit generic routine instantiations in sigmatch (#24010)metagn2024-09-021-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | fixes #16376 The way the compiler handled generic proc instantiations in calls (like `foo[int](...)`) up to this point was to instantiate `foo[int]`, create a symbol for the instantiated proc (or a symchoice for multiple procs excluding ones with mismatching generic param counts), then perform overload resolution on this symbol/symchoice. The exception to this was when the called symbol was already a symchoice node, in which case it wasn't instantiated and overloading was called directly ([these lines](https://github.com/nim-lang/Nim/blob/b7b1313d21deb687adab2b4a162e716ba561a26b/compiler/semexprs.nim#L3366-L3371)). This has several problems: * Templates and macros can't create instantiated symbols, so they couldn't participate in overloaded explicit generic instantiations, causing the issue #16376. * Every single proc that can be instantiated with the given generic params is fully instantiated including the body. #9997 is about this but isn't fixed here since the instantiation isn't in a call. The way overload resolution handles explicit instantiations by itself is also buggy: * It doesn't check constraints. * It allows only partially providing the generic parameters, which makes sense for implicit generics, but can cause ambiguity in overloading. Here is how this PR deals with these problems: * Overload resolution now always handles explicit generic instantiations in calls, in `initCandidate`, as long as the symbol resolves to a routine symbol. * Overload resolution now checks the generic params for constraints and correct parameter count (ignoring implicit params). If these don't match, the entire overload is considered as not matching and not instantiated. * Special error messages are added for mismatching/missing/extra generic params. This is almost all of the diff in `semcall`. * Procs with matching generic parameters now instantiate only the type of the signature in overload resolution, not the proc itself, which also works for templates and macros. Unfortunately we can't entirely remove instantiations because overload resolution can't handle some cases with uninstantiated types even though it's resolved in the binding (see the last 2 blocks in `texplicitgenerics`). There are also some instantiation issues with default params that #24005 didn't fix but I didn't want this to become the 3rd huge generics PR in a row so I didn't dive too deep into trying to fix them. There is still a minor instantiation fix in `semtypinst` though for subscripts in calls. Additional changes: * Overloading of `[]` wasn't documented properly, it somewhat is now because we need to mention the limitation that it can't be done for generic procs/types. * Tests can now enable the new type mismatch errors with just `-d:testsConciseTypeMismatch` in the command. Package PRs: - using fork for now: [combparser](https://github.com/PMunch/combparser/pull/7) (partial generic instantiation) - merged: [cligen](https://github.com/c-blake/cligen/pull/233) (partial generic instantiation but non-overloaded + template) - merged: [neo](https://github.com/andreaferretti/neo/pull/56) (trying to instantiate template with no generic param)
* remove nontoplevel type hack + consider symbol disamb in type hash (#23969)metagn2024-08-161-0/+9
| | | | | | | | | | | | | | fixes #22571 Removes the hack added in #13589 which made non-top-level object type symbols `gensym` because they couldn't be mangled into different names for codegen vs. top-level types. Now we consider the new `disamb` field (added in #21667) of the type symbols in the type hash (which is used for the mangled name) to differentiate between the types. In other parts of the compiler, specifically the [proc mangling](https://github.com/nim-lang/Nim/blob/298ada3412c9cf5971abc2b3b891b9bb8612e170/compiler/mangleutils.nim#L59), `itemId.item` is used instead of the `disamb` field, but I didn't use it in case it's the outdated method.

* Refactor and doc package handling, module name mangling (#19821)quantimnot2022-05-301-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Refactor and doc package handling, module name mangling * Consolidate, de-duplicate and extend package handling * Alter how duplicate module names of a package are handled * Alter how module names are mangled * Fix crash when another package is named 'stdlib' (test case added) * Doc what defines a package in the manual Modules with duplicate names within a package used to be given 'fake' packages to resolve conflicts. That prevented the ability to discern if a module belonged to the current project package or a foreign package. They now have the proper package owner and the names are mangled in a consistent manner to prevent codegen clashes. All module names are now mangled the same. Stdlib was treated special before, but now it is same as any other package. This fixes a crash when a foreign package is named 'stdlib'. Module mangling is altered for both file paths and symbols used by the backends. Removed an unused module name to package mapping that may have been intended for IC. The mapping was removed because it wasn't being used and was complicating the issue of package modules with duplicate names not having the proper package owner assigned. * Fix some tests * Refactor `packagehandling` * Remove `packagehandling.withPackageName` and its uses * Move module path mangling from `packagehandling` to `modulepaths` * Move `options.toRodFile` to `ic` to break import cycle * Changed import style to match preferred style Co-authored-by: quantimnot <quantimnot@users.noreply.github.com>
