* Rename PolyParam --> TypeParamRefMartin Odersky2017-04-0628-173/+166

* Refactor ParamRef so that no type params are neededMartin Odersky2017-04-064-51/+31
|
* Disable -strict when compiling dotty.Martin Odersky2017-04-061-3/+3
| | | | | | It seems we need a more refined way to deal with non-variant variables in pattern matches. See branch change-patmat-undet for a WIP. For the moment we disable -strict to be able to compile latest version of dotty. (reverted from commit c8fe830f8a382eb965c2231064fa286ee8f0a4ec)

* Get rid of Name parameter for LambdaType and ParamRefMartin Odersky2017-04-064-24/+32
| | | | Use an abstract type instead.
* ParamType refactoringsMartin Odersky2017-04-064-77/+78
| | | | Trying to bring PolyTypes closer to TypeLambdas
* Harmonize paramTypes and paramBoundsMartin Odersky2017-04-0643-213/+216
| | | | | | MethodTypes have paramTypes whereas PolyTypes have paramBounds. We now harmonize by alling both paramInfos, and parameterizing types that will become common to both.
* Break out functionality from MethodTypeMartin Odersky2017-04-0620-134/+176
| | | | | and generalize MethodParam to ParamRef, and TypeParamInfo to ParamInfo
* Drop name checking scheme for type parametersMartin Odersky2017-04-062-10/+3
| | | | | It was a red herring. Symbolic names are expanded anyway to $plus / $minus, so they can't be confused with a variance prefix.
* Don't let illegal parameter names propagate into typesMartin Odersky2017-04-061-4/+4
|
* Fix dottydoc parameter printingMartin Odersky2017-04-061-4/+1
|
* Add neg test for illegal parameter namesMartin Odersky2017-04-062-1/+2
| | | | and fix typo
* Encode variances in parameter namesMartin Odersky2017-04-0613-41/+76
| | | | | | | | | | This leads to a slight overall simplification, harmonizes pickle format with internal representation, and makes MethodTypes and PolyTypes more similar to each other. I believe the change is useful as it is, but in particular it is a useful step for an eventual unification of MethodTypes and PolyTypes.
* Merge pull request #1958 from dotty-staging/add-enumodersky2017-04-0647-184/+834
|\ | | | | Add "enum" construct
| * Emit enum utility methods only if enum class is not genericMartin Odersky2017-04-061-6/+8
| |
| * Another test fixedMartin Odersky2017-04-051-1/+1
| |
| * Update test and add check fileMartin Odersky2017-04-052-1/+9
| |
| * Implementation of proposal changesMartin Odersky2017-04-055-50/+107
| | | | | | | | | | - rename utility methods - generate utility methods also for object cases
| * Add check fileMartin Odersky2017-04-051-0/+1
| |
| * New and updated testsMartin Odersky2017-04-044-3/+37
| |
| * Infer enum type args from type parameter boundsMartin Odersky2017-04-042-12/+57
| | | | | | | | | | | | Infer type arguments for enum paraments from corresponding type parameter bounds. This only works if the type parameter in question is variant and its bound is ground.
| * Fix rebase breakageMartin Odersky2017-04-041-1/+1
| |
| * Avoid assertion failure on neg testMartin Odersky2017-04-041-1/+8
| | | | | | | | This commit can hopefully be reverted once #2121 is in.
| * Fix neg test error countMartin Odersky2017-04-041-1/+1
| | | | | | | | | | Previous expansion caused 3 spurious follow-on errors which are now avoided.
| * Support cases with type parameters that extend a non-parameterized baseMartin Odersky2017-04-043-16/+46
| | | | | | | | | | | | | | | | Support cases with type parameters that implicitly extend a non-parameterized base without needing their own extends clause. The proposal has been updated to make clear that this is supported. Also address other reviewers comments.
| * Support comma-separated enum constantsMartin Odersky2017-04-045-30/+48
| |
| * Change enumeration members.Martin Odersky2017-04-045-26/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | Based on the discussion in #1970, enumeration objects now have three public members: - valueOf: Map[Int, E] - withName: Map[String, E] - values: Iterable[E] Also, the variance of case type parameters is now the same as in the corresponding type parameter of the enum class.
| * Change return type of `apply`.Martin Odersky2017-04-042-8/+11
| | | | | | | | | | | | | | | | | | | | | | In an enum case like case C() extends P1 with ... with Pn ... apply now returns `P1 & ... & Pn`, where before it was just P1. Also, add to Option test.
| * Don't change the return type of the `copy` methodMartin Odersky2017-04-041-1/+1
| | | | | | | | | | `copy` should always return the type of it's rhs. The discussion of #1970 concluded that no special treatment for enums is needed.
| * Check that cases with type parameters also have an extends clauseMartin Odersky2017-04-042-1/+6

| * Fix typo in syntaxMartin Odersky2017-04-041-1/+1

| * Fix cheeky comment in nested scopeFelix Mulder2017-04-042-6/+47

| * More fine-grained distinctions when flags are defined.Martin Odersky2017-04-044-9/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Flags like Trait are in fact not always defined when a symbol is created. For symbols loaded from class files, this flag, and some other is defined only once the classfile has been loaded. But this happens in general before the symbol is completed. We model this distinction by separating from the `FromStartFlags` set a new set `AfterLoadFlags` and distinguishing between the two sets in `SymDenotations#is`. Test case is enum-Option.scala. This erroneously complained before that `Enum` was not a trait.
| * Fix typoMartin Odersky2017-04-041-1/+1
| |
| * New test caseMartin Odersky2017-04-043-0/+44
| |
| * Be more systematic about result of apply methodMartin Odersky2017-04-041-8/+18
| | | | | | | | | | | | The same type needs to be used as a result type for the copy method, and the function type implemented by the companion module.
| * Link generic test to actual implementations of Enum and EnumValuesMartin Odersky2017-04-043-26/+2
| | | | | | | | These are now implemented in scala.runtime.
| * Another testMartin Odersky2017-04-042-0/+11
| |
| * Make `getDocComment` referentially transparentFelix Mulder2017-04-041-36/+12
| |
| * Fix "closest" computation for docstringsMartin Odersky2017-04-041-1/+3
| |
| * Improvement to REPL testMartin Odersky2017-04-041-1/+4
| | | | | | | | In case of difference, dump transcript to file for easier comparisons.
| * Comment out unused method in ContextMartin Odersky2017-04-041-2/+3
| |
| * Add testsMartin Odersky2017-04-047-0/+47
| |
| * Implement enum desugaringMartin Odersky2017-04-046-36/+215
| |
| * Change handling of enum defs.Martin Odersky2017-04-042-15/+34
| | | | | | | | | | | | | | The previous scheme did not work because desugaring cannot deal with repeated expansions. We now sidestep the issue by doing the expansion in the parser. Luckily, positions work out perfectly, so that one can reconstruct the source precisely from the parsed untyped trees.
| * Adapt generic tests to model modified enum values schemeMartin Odersky2017-04-045-21/+35
| |
| * Allow value expansion of modules in mergeCompanionDefsMartin Odersky2017-04-041-1/+0
| |
| * Simplify syntaxMartin Odersky2017-04-046-17/+17
| | | | | | | | `enum' only allowed as a prefix of classes, dropped from traits and objects.
| * Don't pass docstring as a parameter.Martin Odersky2017-04-041-39/+33
| | | | | | | | | | It's completely redundant, docstring is just the comment found at the `start` offset, which is passed anyway.
