From a8758de5bc19e5adb3f618d3038743a164f09912 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Hannu=20Niemist=C3=B6?= Date: Tue, 20 Dec 2016 12:09:30 +0200 Subject: [PATCH] Merged changes from feature/scl to master. This commit contains lots of SCL compiler and runtime changes: * New CHR-rule based sublanguage. This change alters meaning of when-keyword and so some code using when may break. * Removed type classes Eq and Hashable. Compiler now generates and uses Java methods equals and hashCode. This change is needed for better interoperability with Java code. * Type based overloading for symbols imported from different modules * Some expressions ignore their return value (statements in do/let/where, if and match cases if the return value of if/match is ignored). These expressions can have any type and if/match expression branches may have different types. Also if-expressions may have only else branch. If the return value of apply-experssion is ignored, the expression cannot be partial application that does not have side-effects. * View pattern support (https://ghc.haskell.org/trac/ghc/wiki/ViewPatterns) * Lambda-match support (https://ghc.haskell.org/trac/ghc/wiki/LambdasVsPatternMatching) * String interpolation can be used also in patterns * SCL compiler regression test suite has been moved to a new bundle org.simantics.scl.compiler.tests * Improvements to SCL module editor syntax coloring * SCL compiler refactorings, for example all name constants are now in a dedicated class Names and CompilationContext merging old context classes * Improved byte code for comparisons * Improved code generation from string interpolation * Anonymous object support in SCL backend (not yet frontend support) * Bugfixes and new regression tests refs #6888 Change-Id: I9d4c001d0323069d3b86a83369fa3581f02ee305 --- .../scl/Simantics/Image.scl | 1 -
