From a907887158a469b6a21d027fd37bc360e9009b2f Mon Sep 17 00:00:00 2001 From: Eugene Burmako Date: Thu, 22 May 2014 22:21:10 +0200 Subject: adds MacroPlugin.pluginsIsBlackbox This is an important omission in the current macro plugin API, which was designed before the blackbox vs whitebox separation was implemented. Even if one overrides pluginsTypedMacroBody and pluginsMacroExpand, that would still be not enough to write a custom macro expander, because typedImplicit1 uses isBlackbox, which is tightly coupled with the standard way of reading/writing macro signatures. --- src/compiler/scala/tools/nsc/typechecker/Macros.scala | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-) (limited to 'src/compiler/scala/tools/nsc/typechecker/Macros.scala') diff --git a/src/compiler/scala/tools/nsc/typechecker/Macros.scala b/src/compiler/scala/tools/nsc/typechecker/Macros.scala index f4456998c0..aa7a570937 100644 --- a/src/compiler/scala/tools/nsc/typechecker/Macros.scala +++ b/src/compiler/scala/tools/nsc/typechecker/Macros.scala @@ -263,7 +263,12 @@ trait Macros extends MacroRuntimes with Traces with Helpers { } def isBlackbox(expandee: Tree): Boolean = isBlackbox(dissectApplied(expandee).core.symbol) - def isBlackbox(macroDef: Symbol): Boolean = { + def isBlackbox(macroDef: Symbol): Boolean = pluginsIsBlackbox(macroDef) + + /** Default implementation of `isBlackbox`. + * Can be overridden by analyzer plugins (see AnalyzerPlugins.pluginsIsBlackbox for more details) + */ + def standardIsBlackbox(macroDef: Symbol): Boolean = { val fastTrackBoxity = fastTrack.get(macroDef).map(_.isBlackbox) val bindingBoxity = loadMacroImplBinding(macroDef).map(_.isBlackbox) fastTrackBoxity orElse bindingBoxity getOrElse false -- cgit v1.2.3
