Tagged Smalltalk/X 8.0.0

CI: Use VM provided by Pharo team on both Linux and Windows. Hand-crafter Pharo VM is no longer needed as the Linux slave in SWING build farm has been upgraded so it has compatible GLIBC. This makes CI scripts simpler and more usable for other people.

For tests on Pharo 5.0, use Spur VM

Oops, another type (`url`, should be `curl`) Sigh.

Oops, forgot to export PETITCOMPILER_DATA_DIRECTORY variable ...so Smalltalk code could not read it. Also fixed test for "include" scripts so they are not downloaded again when already downloaded.

Use shared directory for test data on Jenkins ...in order to save bandwidth and disk space.

Fixed CI scripts on Windows For an unknown reason, unzip on Windows reports status code 50 (presumably "the disk is (or was) full during extraction.") even if there's plenty of space. To workaround this, simply ignore status code 50 on Windows. Sigh.

Fixed CI scripts for PetitParser.

Added CI scripts for PetitParser.

Added README and LICENSE

Portability: Removed tests/asserts referring to BlockClosure Due to historical reasons, there's no BlockClosure in Smalltalk/X, the class is named Block. Conversely, there's no Block in Squeak/Pharo.

Oops, re-added list splicemap for stx:goodies/petitparser/compiler It somehow got lost during merge

Forge Monticello ancestry when exporting .mcz Generate ancestry based in Mercurial history and individual package's splice maps.

Portabiluty: use `Exception new signal: message` to throw exceptions ...instead of #signalWith: It seems that this is the only portable way to throw exceptions (at least among Pharo and Smalltalk/X)

Poratbility: do not use #removeAtIndex: under Pharo. Pharo does not have #removeAtIndex: which is actually and ANSI protocol. But Pharoers do not like ANSI and don't give a shit about compatibility. To workaround it, use super-ugly #respondsTo: test.

Use #skipIf: instead of <skip>

Added ,mcz export by-producsts to .hgignore

Merge

Updated splicemaps.

PPCConfiguration refactoring: [10/10]: Cleaned up compilation API The main compilation method is now PPParser>>compileWithOptions: Removed oither old and unused compilation methods from PPParser and other PetitCompiler classes.

PPCConfiguration refactoring: [9/10]: Renamed PPCConfiguration to PPCCompiler.

PPCConfiguration refactoring: [8/10]: Cleaned up compilation API. Methods in PPCConfiguration not meant for public use have been moved to private protocol to make it clear.

PPCConfiguration refactoring: [7/10]: allow to configure passes ...run during compilation by setting a collection of passes to run. Got rid of PPCPluggableConfiguration and PPCConfiguration subclasses. Removed a bunch of options used to suppress certain passes.

PPCConfiguration refactoring: [6/10]: use #runPass: instead of self-sends. ...in PPCConfiguration>>invokePhases. This is a preparation for removing #invokePhases completely and configuring the compilation via list of phases.

PPCConfiguration refactoring: [5/10]: Commented options in PPCCompilationOptions. So it's more clear for what the option is and how to use it. This is a base for user-documentation as options are meant to be set by the end user.

PPCConfiguration refactoring: [4/10]: introduced a class - PPCPass ... representing a compilation pass over the PPCNode tree. The pass has a common api method: #run:in: which is not used in PPCConfiguration. This simplifed the code and removed some code duplication.

PPCConfiguration refactoring: [3/10]: Moved some sime instvars to context Move some context-related options from PPCConfiguration to PPCCompilationContext. PPCConfiguration now access them wia accessor methods.

PPCConfiguration refactoring: [2/10]: introduced PPCCompilationContext Moved parser class/scanner class instvars from PPCConfiguration subclasses to the context. Made PPCConfiguration to keep an instance of context. This is a preparation for having only one PPCConfiguration-like class.

PPCConfiguration refactoring [1/10]: renamed PPCArguments to PPCCompilationOptions Renamed PPCConfiguration>>#arguments/#arguments: to #options/#options:

Removed unused (obsolete) class PPCCompiledMethod

Added missing #new methods

Fixed PEGFsaState>>isFailure: it is not obsolete, actually.

Fixed PEGFsaTransition>>disjunction: - xor: does not take blocks as xor is not subject to lazy evaluation. While in Pharo it worked, it does not work well under Smalltalk/X which does not send value to the passed argument. (partially because xor: is inlined by the stc/JIT compiler)

Fixed support for Smalltalk/X end-of-line comments in PPSmalltalkGrammar.

Fixed LRP tests. Removed tests for tokendized LRPParser (not yet supported)

Added benchmarks for Johan's LRP Parser

Portability: fixed RBLiteralValueNode>>isLiteralNumber to work under both - Pharo and Smalltalk/X

Portability fixes * do not use Object>>asString. Not all Smalltalks implement it. * do not use Object>>name. Not all Smalltalks implement it. * do not use Dictionary keysAndValuesRemove:. Not all Smalltalks implement it. * do not use Class>>methods The semantics is different among Smalltalks. Use `Class methodDictionary values` instead. * do not modify dictionary in #at:ifAbsentPut: block!

Portability: override #new for PPCScannerCodeGenerator. Not all smalltalks send #initialize by default.

Fixed PPCSetUpBefore...Resource to work on Pharo. Few othr minor Pharo fixes.

Portability fix: do not use "/ style comments in PetitParser code.

Added smoke tests for LRPParser

Added LRPParser from Live Robots Prograaming project

Tests refactoring - use generated test cases to make sure all posibilities are tested. Do not generate resource for all combinations, use PPCSetUpBeforeTearDownAfterResource instead that delegates parser compilation to the testcase itself (it calls it's #setUpBefore method).

Inline child of an action node only is its unnamed sequence node. Named nodes should not be inlined as they should make a method. There's little point in inlining non-sequence nodes, so don't enforce inlining on those. Some (JK :-) may prefer them non-inlined (for debugging purposes)

Temporarily disabled #acceptsEpsilon test in PPCTokenizingCodeGenerator>>visitChoiceNode: JK should have a look and come up with proper solution.

Workaround for stc bug.

Added static analysis of blocks when inlining. Allow inlining only when block is functional ...i.e., does not access any shared state (in instance or class variables). If the block does a self-send, the sent method has to be (transitively) functional too. To allow for self-sends in action blocks, copy (transitively) self-sent methods to target parser. This is safe as these self-sent methods are guarnateed to be functional.

Post-merge fixes. PPCCodeBlock refactoring.

Portability fix: override #new for class that implements #initialize #initialize is not sent by default.

Moved PPMappedActionParser>>asCompilerNode to protocol 'converting' If in '*petitparser' it makes some problems with Monticello.

Use RBVariableNode>>name: to change variable's name. The old way - `node token value:` is working in Pharo - there's no token in RBVariableNode. Sigh.

Portability fix: do not use #? ...use `notNil ifTrue:[] ifFalse:[]` instead. #? is not supported in Squeak/Pharo

Moved PPCMappedActionNode to category PetitCompiler-Nodes

Do not use RBProgramNode>>variableNodesDo: as this method is not present in Pharo. Use local helper method instead.

Reverted fc3dbe5654c5: sending #copy should be OK (copy set's parent properly)

Send #sourceNode instead of #ast as there's no #ast in Pharo ...I was mistaken.

Oops, removed EOL comments as they;re not supported in Squeak / Pharo

Fixed target mcz - exit Smalltalk after all packages are exported.

Use #deepCopy instead of #copy when copying RB parse tree ...because #copy make a copy if child nodes but does not set their parents properly. Therefore node replacing does not work because it replaces it in wrong tree (original, not the copy).

Codegen: added support for smart action node compiling. Avoid creation of intermediate result collection for action nodes if all references to action block's argument (i.e., the nodes collection) is in form of: * <nodes> at: <numeric constant> * <nodes> first (second, third...

Oops, renamed testMappedNode3/4/5 to testActionNode3/4/5 which is the correct name!
