Replace `ifNil:[...]` with `isNil ifTrue:[...]` The latter is optimized by compilers and therefore faster.

Issue #239: Fix all Smalltak/X source files to be in unicode (UTF8 without BOM) and prefixed by "{ Encoding: utf8 }" when any unicode character is present - All source *.st files are now Unicode UTF8 without BOM Files are in two groups (fileOut works this way in Smalltalk/X): - containing a unicode character have "{ Encoding: utf8 }" at the header - ASCII only are without the header

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.

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!

Fix in codegen for inlined sequence nodes. For inlined sequence nodes, generate nested ifs rather than sequential code which does not work when inlined. The reason is that #codeReturn: in inline generates instvar assignment, not method return, so in sequential code the next child of a sequence will be probed even if previous failed. If that happends, the whole sequence fail and therefore we must generate nested ifs to correctly handle this w.r.t. inlining.

Avoid creation of intermediate collection for mapped action nodes.

Fix in codegen: fixed compilation of unknown node: do not hardcode return variable name ...use `self retvalVar` instead

Renamed #codeStoreValueOf:intoVariable: to #codeAssignParsedValueOf:to: to use same naming as #codeAssign:to:

Fixed codegen for empty (mapped) action block. Although empty blocks are useless in practice, they may occur (and do occur in tests)

Do not create intermediate collection when parsing sequence if not necesary. The collection is not needed when the result of a choice is being used in mapped parser. In that case, store parsed objects in variables and inline action code to use these variables to access parsed objects.

Oops, fixed subproject definition (wrong package names)

Updated .mcz exporting code to include a commit message digest ...instead of just exported revision commit message.

Introduced PPCMappedActionNode for PPMappedActionParser. It's compilation is not yet ideal, bot works for now.

Introduced PPMappedActionParser, a specialized parser for map:ped actions. In order to compile nicer code, compiler has to be able to tell between simple (==>) action parser and mapped (map:) action parser.

Action inlining [1/x]: Initial support for inlining actions parsers (i.e., ==>) The code of the action is now inlined into parsing method rather then delegated to stored block. Mapping parser (i.e., map:[...]) are not supported and not detected, so using them cause crash. This will be fixed later.

Codegen refactoring [2/x]: Added PPCCompiler>>codeIf:then:else: this allows for more structured coding of conditionals. then/else code is evaluated inside new block so it may allocate its own temporaries.

Codegen refactoring [1/x]: Introduced a PPCCodeBlock A PPCCodeBlock is an abstraction of a block of statements with temporaries. This will allow for scoped temporary management in code generator - temporary variables could be allocated for block only. (i.e., make them block-temporaries)

Fixed choice inlining.

Add inspector tab to present parser tree.

More fixes for inlining of nodes

Oops, merged code which contained Pharoism's

Avoid using of a bridge parser for top-most composite parser ...by converting PPCompositeParser to PPCDelegatePrser.

Added two more tests for inlining

Added inspector representation to show PPC node tree.

Oops. re-added classes lost during merge...

Indent by 4 spaces on Smalltalk/X

Fixed code generation for deterministic choice w.r.t inlining For PPCDeterministicChoiceNode generate code in form if () else if () else if () else error instead of sequence of ifs. The former is safe w.r.t inlining.

Fixed MNU in PPCSpecializingVisitor>>visitTrimmingTokenNode: node Set child of PPCTrimmingCharacterTokenNode before setting name as child is used to compute meaningful name.

Do not try to inline PPCPluggableNode on Smalltalk/X Sadly, on Smalltalk/X blocks cannot be inlined because the VM does not provide enough information to map it back to the source code. Very bad indeed!

Compatibility fixes: * do not use 'class methods size', use 'class methodDictionary size' * do not use 'class methods do:', use 'class methodDo:'

Merged JK's work on PetitCompiler Name: PetitCompiler-JanKurs.57 Author: JanKurs Time: 05-11-2014, 05:10:47 AM UUID: 4c625efe-77fd-465d-bd63-72ead0b5d3ba Name: PetitCompiler-Tests-JanVrany.13 Author: JanVrany Time: 05-11-2014, 09:31:07 AM UUID: 189ae287-6bc1-40ba-8458-b8392c4260a0

Classes renamed to ease following merge wirh Pharo version. * PetitBenchmark renamed to PPCBenchmark * PetitBenchmarkSources renamed to PPCBenchmarkResources * PetitCompilerTest renamed to PPCCompilerTest

Fixed mcz make target.

Removed PPTrimmingParser>>trim

Portability fixes in PPPredicateTest>>charactersDo: / parsedCharacterSet: * It is my understanding that charactersDo: should iterate over all signle byte characters. If so, the method suffer from off-by-one error, it should generate characters with code points 0..255. 256 is actually a two-byte character. Method changed accordingly. * Use Character>>asString instead of `String>>with:` which is safer w.r.t. multi-byte characters. Under Smalltalk/X, String may contain only signle byte characters.

Removed weird PPExtensionTest>>testOrdered

Removed obsolete Character>>ppMinus:

Removed unused / obsolete methods from PPToken * remove PPToken class>>on:start:stop * remove PPToken>>initializeOn:start:stop

Removed PPRepeatingParser>>parseOn: - class is now abstract

Merged PetitParser and PetitTests Name: PetitParser-JanKurs.253 Author: JanKurs Time: 30-10-2014, 03:55:46 AM UUID: c7100f9c-e875-4453-8f26-e0c91dd49b91 Name: PetitTests-JanKurs.63 Author: JanKurs Time: 30-10-2014, 12:54:37 PM UUID: 7afbeef7-eadf-4d65-bce5-7204e2727edb

Removed class PPAbstractParseTest. It was a duplicate of PPAbstractParserTest.

Removed autoload attribut for tests. As all classes are in a test package, when package is loaded likely tests are required, so load them right away.

Reverted back change from `assert: x equals: y` to assert: (x = u). Actually, even Smalltalk/X SUnit has assert:equals:

Portability fix: do not use Behaviour>>methods. On Smalltalk/X it returns a category reader (in order to be able to read Dolphin fileouts): * use`class methodsDo:` instead of `class methods do:` * use `class methodDictionary size` instead of `class methods size`

Fixed PPCCompiler: must refetch class afer updating instance variables of a given class. The reason is, that in (at least) Smalltalk/X modyfing a layout of a class results in creating a new class rather than updating an old one and migrating instances, i.e., the old class is not identical with the new class. Therefore, to install methods in in correct class, we have to refetch new version from system dictionary. On Pharo it should not harm

Fix in PPCMethod>>addVariable: make sure variable is added only once. Having two variables with the same name is forbidden.

Added teardown to PetitCompilerTests to clean up a generated parser after tests.

Portability fix PPCAbstractCharacterNode>>body: use #storeString instead of #printString.

Fixed PPCGuard>>compileCharacter: Use #storeString instead of #printString - #storeString is defined as string whose evaluation would return the receiver (resp. object equal to reveiver).

Portability fix in PPCompiler>>cleanGeneratedMethods: Use more portable coding.

Portability - test if RPackageOrganizer is present... ...if not, do not register new package using it. RPackage is Pharo specific thing not present in other Smalltalks.

Override #new in classes that implement #initialize. Not all Smalltalks call #initialize automatically. Actually, mose of them does not.

Fixed PPCNode>>doOptmizationLoop:status: Must report status to changeStatus as caller is checking its value. Also, added PPCOptimizationResult class>>new as Smaltalk/X (actually, most Smalltalks) does not call #initialize by default.

Ported PetitCompiler-(Tests).

Updated to PetitSmalltalk-JanKurs.75 Author: JanKurs Time: 13-10-2014, 05:00:14 AM UUID: 6254f8f7-aa47-4ddd-a373-167bccb0d4e5 Ancestors: Smalltalk token decomposed into the PEG expression

Updated smalltalk parser to PetitSmalltalk-JanKurs.75 Name: PetitSmalltalk-JanKurs.75 Author: JanKurs Time: 13-10-2014, 05:00:14 AM UUID: 6254f8f7-aa47-4ddd-a373-167bccb0d4e5

Workaround to fix PPComposedTest>>testLeftRecursion - make PPStream>>size returning size of the input. For whatever reason, in Smalltalk/X ReadStream>>size returns size remaning data, not the size of a whole stream. This is a bug and should be fixed in Smalltalk/X libbasic. Meanwhile, override PPStream>>size to return proper value. In Pharo, the method is not needed as the inherited method is exactly the same.

Commited a island parser support (MC package PetitIslands) Name: PetitIslands-JanKurs.10 Author: JanKurs Time: 06-10-2014, 11:50:57 AM UUID: 19560ad2-4899-43d5-8c69-cf7274ad4f04 Repository: http://smalltalkhub.com/mc/Moose/PetitParser/main

Smalltalk parser almost fixed (except few pragma-related tests). Code is bit ugly sometimes....

Commited a Smalltalk parser (MC package PetitSmalltalk) Name: PetitSmalltalk-JanKurs.71 Author: JanKurs Time: 19-08-2014, 02:18:05 AM UUID: d1d11836-f3e2-4709-abd3-e2ff3b72d7c4 Repository: http://smalltalkhub.com/mc/Moose/PetitParser/main Ancestors: Fixes to be compatible with PPContext

Fixed stx_goodies_petitparser_analyzer class>>testSuite Return testsuite from stx:goodies/petitparser/analyzer/tests.

Removed leftover Smalltalk/X-ism: end-of-line comments. Not supported by Pharo.

Added target `mcz` to export .mcz package out of Smalltalk/X package.

`PPParser>>allParsers`, `allParsersDo:(seen:)` moved to base PetitParser package. The method #allParsersDo: is actually used used by PPContext>>initializeFor: therefore it has to be in the package stx:goodies/petitparser (MC package PetitParser) and _NOT_ in stx:goodies/petitparser/analyzer (MC package PetitAnalyzer)

Remove Pharoisms to make code more portable and running on Smalltalk/X * Use ANSI `(Character codePoint: 13)` (`10`) instead of `Character cr` (`lf`), This is more portable and does not depend on dialects interpretation of `#cr` - Smalltalk/X convert it according to platform line end convention (UNIX/Windows/Mac) * Do not assume exact value of a printstring in tests, i.e., instead of `msg includesSubstring: '$a' code `msg includesSubstring: $a printString. This way, the test is independent on the printString value, which may differ among dialects. Q: Is printString value of String and/or Character defined in ANSI? * In assestions, instead of `#equals:` use plain old `#=`, which is more portable. * Removed Character>>- used to create range parser. Use portable `(Interval from: $a to: $z) asParser` instead of just `$a - $z`. Do not use ($a to: $z) asParser as in Pharo, Character>>to: does not create an Interval but an Array (sigh).

Some tests fixed.
