AST Transformation Techniques
by sean＠clipperadams.com Nov. 18, 2020

Nov. 18, 2020

To generate code, I used to use templates like the following (contrived example): \`\`\`smalltalk `template := 'method1` ` ^ {returnValue}'.` `template format: { #returnValue -> 2 } asDictionary` \`\`\` This is \*okay\* for simple cases, but can get unwieldy, and doesn't benefit from e.g. (early) compiler warnings. It is also lacking when one wants to offer the behavior as a method and also as a script with no dependencies (maybe for CI). To overcome some of these limitations, I started saving the code template as an actual method and transforming the AST, e.g.: \`\`\`smalltalk `"Convert baseline##: method"` ` methodTree := (self methodNamed: selector) parseTree.` ` methodTree selector: #baseline:.` ` methodTree pragmas at: 1 put: (RBPragmaNode selector: #baseline arguments: #()).` ` commonBlockBody := methodTree statements first arguments last body.` ` commonBlockBody statements` ` detect: [ :e | e selector = #repository: ]` ` ifFound: [ :repoSetter | commonBlockBody removeNode: repoSetter ].` ` ` ` "Compile baseline method"` ` baseline compile: methodTree newSource classified: 'baseline'` \`\`\` When I started doing this, I noticed two things: 1\. There were idioms that were repeated over and over. 2\. It still isn't super easy to turn a method into a script with no dependencies (e.g. self sends) So, I did a spike to wrap a few common idioms for this use case. It works like this. Say you have a method like this: \`\`\` `SmallRemoteGitRepository>>#addRemote: urlString as: nameString` ` "Assumes repo is loaded"` ` ` ` | repo remote |` ` repo := IceRepository registry detect: [ :e | e name = self projectName ].` ` remote := IceGitRemote name: nameString url: urlString.` ` repo addRemote: remote.` ` remote fetch` \`\`\` And you want to also provide it as source code for a script with no dependencies. You can do: \`\`\` `SmallRemoteGitRepository >>#scriptToAddRemote: urlString as: nameString` ` | method transformer |` ` method := SmallRemoteGitRepository methodNamed: #addRemote:as:.` ` transformer := method peAST_Transformer` ` beScript;` ` addStatementFirst: #projectName , ' := ' , self projectName printString;` ` addStatementFirst: #nameString , ' := ' , nameString printString;` ` addStatementFirst: #urlString , ' := ' , urlString printString;` ` replaceNodeDetect: [ :e | e isMessage and: [ e selector = #projectName ] ]` ` withNode: (RBVariableNode named: #projectName).` ` ^ transformer newSource` \`\`\` which would generate (for example, for a particular instance): \`\`\` `| repo remote projectName |` `urlString := 'git@github.com:magritte-metamodel/magritte.git'.` `nameString := 'upstream'.` `projectName := 'Magritte'.` `repo := IceRepository registry detect: [ :e | e name = projectName ].` `remote := IceGitRemote name: nameString url: urlString.` `repo addRemote: remote.` `remote fetch` \`\`\` So my questions are: \- Does something like this already exist? \- Are there better ways to solve this problem? \- Does this solution look promising/generally-helpful?

Nov. 12, 2020

We merged 20 pull requests and closed 17 issue tracker entries this week. For someone interested in following this more closely: Github has a feature to get an email for all the changes that happen in both the issues and the pull requests. To get emails for those, on the github page you can (after logging in), "watch" the repository. https://github.com/pharo-project/pharo/ There are more PRs done but not merged, they often just need a final review! You can find them here: https://github.com/pharo-project/pharo/pulls Merge spec 0.7.6 #7713 ====================== Spec is an example of a project that is developed in itâs own repository and then merged only when a release is done. We merged 0.7.6 this week, it consists itself of many commits, of course. Here is the ChangeLog: - several enhancements and bugfixes to SpPopoverPresenter. - in SpStyle, introduced the concept of environment variables. Now we can define EnvirontmentFont and EnvironmentColor to reference environment defined variables. - fixed usage of minWidth/minHeight in styles. - fix pharo-spec/Spec#960 - fixed in how SpBoxLayout calculates widths and heights, allowing the toolbar to take its real place. - fixed alignments in SpBoxLayout (hAlign* and vAlign* options now work properly). - added SpToolbarPopoverButtonPresenter. - SpMillerColumnPresenter now understands removeAllFrom: - in tables, fixed the usage of showColumnHeaders (now it show headers even if headers are nil). - in tables, fixed image columns with fixed widths (now calculate correctly the width). - SpCodePresenter commands use new selector extractor. First Class Variables ===================== - Simplify-MetaLinkInstaller #7669 This PR simplifies MetaLinkInstaller by taking advantage of the new unified Variable hierarchy. (first step, more can be done) https://github.com/pharo-project/pharo/pull/7669 - Unify-OCInstanceScope-Behavior #7704 Simplify Name Analysis even more. self/super and friends are now looked up in the global scope. https://github.com/pharo-project/pharo/pull/7704 Debugger Improvements ===================== - Added <debuggerCompleteToSender> pragma to user-level object error-handling protocol methods #7714 (this fixes TDD style development for these cases) https://github.com/pharo-project/pharo/pull/7714 - Return the package column to the debugger #7700 https://github.com/pharo-project/pharo/pull/7700 Fluid Class Definition ======================= Work is progressing... - 7706-New-class-definition-does-not-like-superclass-change #7717 https://github.com/pharo-project/pharo/pull/7717 - 7687-Cannot-remove-a-Trait-written-with-the-fluid-syntax #7689 https://github.com/pharo-project/pharo/pull/7689 - 7522--Fluid--Adding-Setting-for-fluid-Syntax #7686 https://github.com/pharo-project/pharo/pull/7686 - 7690-fluid-printer-has-some-duplicated-logic- #7691 https://github.com/pharo-project/pharo/pull/7691 - 7684-New-trait-UI-wizard-cannot-display-the-package-name-in-apostrophe #7697 https://github.com/pharo-project/pharo/pull/7697 Fixes ===== Fix issue 7703: Build 817 has broken parser #7703 #7708 https://github.com/pharo-project/pharo/pull/7708 Returning default error value only on Error #7705 https://github.com/pharo-project/pharo/pull/7705 fix-fasttable-minHeight #7685 https://github.com/pharo-project/pharo/pull/7685 Cleanups ======== EmbeddedFreeTypeFontFontDescription should be EmbeddedFreeTypeFontDescription https://github.com/pharo-project/pharo/pull/7709 Typo in ClyClassWithUndeclares class comment #7707 https://github.com/pharo-project/pharo/pull/7707 7682-ClassHierarchyPrinter-on-steroid-should-be-back- #7683 https://github.com/pharo-project/pharo/pull/7683 Cleanup Files-Tests package #7712 https://github.com/pharo-project/pharo/pull/7712 CleanBlockChecker-Cleanup #7666 https://github.com/pharo-project/pharo/pull/7666

NewTools and Spec merge ==================== https://github.com/pharo-project/pharo/pull/7510 v0.4.5 - StInspector and StDebugegr now uses a paginator to better show miller collumns. - Some minor bugfixes - Activated CI NewTools v0.4.4 - new tool SystemReporter (thanks Stef) - some changes on debugger inspector ui, looking to make things more pleasant. - fixes pharo-spec/NewTools#120 - fixes pharo-spec/NewTools#113 - fixes #6940 - fixes #7456 - fixes #7453 - fixes #7451 Spec2 v0.7.5 - SpFilterWithListPresenter was renamed to SpFilteringListPresenter. - lists and trees now use displayIcon: to answer an icon instead icons:. - new presenters SpPaginatorPresenter and SpMillerPaginatorPresenter. - Add decoration attributes to SpStringTableColumn - several fixes to SpMillerColumnPresenter. - fixes pharo-spec/Spec#952 - fixes pharo-spec/Spec#940 - fixes pharo-spec/Spec#954 - fixes pharo-spec/Spec#929 - fixes pharo-spec/Spec#871 - ... and several other bugfixes Breakpoints =========== Some fixes related to styling. Merge-MetaLinkStyler #7596 https://github.com/pharo-project/pharo/pull/7596 535-Variable-Breakpoints-Wrong-Icon-in-gutter #7551 https://github.com/pharo-project/pharo/pull/7551 First Class Variables ===================== 6001-isTemp-might-fail-on-Pharo-AST #7586 This PR intruduces UnresolvedVariable. When the AST is created by the parser, it sets all Variables to this kind. This allows us to - get a meaningful answer to all is*Variable checks: false (as it is not eg. a temp yet) - visitor works correctly and falls back to #visitVariable node no need for any ifs - nice errror messages if you try to generate code https://github.com/pharo-project/pharo/pull/7586 Read-Only Literals ================== isReadOnlyLiteral-Float-Integer #7553 Float and Integers are now read-only if they are referened from the code and not immediate https://github.com/pharo-project/pharo/pull/7553 7592-add-beRecursivelyReadOnlyObject #7593 We have beReadOnlyObject, but often it makes sense to set an Object recursively read-only. One example we see with literal arrays: right now we just make the outer array read-only, but we should recurse into it and make all the content read-only, too. Based on the RecursiveWriteBarrier package by khinsen, with small improvements: - after we merged #7590 , we do not need the exception handler anymore - instead of using instVarNamed:, we should use #instanceVariables and then the reflective read/write API of the first class variable objects https://github.com/pharo-project/pharo/pull/7593 7589-isReadOnlyObject-and-beReadOnlyObject-are-not-consistent-wrt-immediate-objects #7590 1 isReadOnlyObject returns true, but calling #beReadOnlyObject raises an error. #isReadOnlyObject has an explicit check for this case in the fallback code, we should add the same to #beReadOnlyObject. https://github.com/pharo-project/pharo/pull/7590 7591-We-have-isImmediateClass-add-isImmediateObject #7594 https://github.com/pharo-project/pharo/pull/7594 Variables-use-pushLiteral #7597 For both MetaLinks and Slots we added code in the past to not use pushLiteral: directly. The idea was that this would be needed for read-only litereals. But the implementation of read-only literals is now that only literals are compiled read-only, we can use the literal frame to e.g. reference Variables or MetaLinks without any problem. https://github.com/pharo-project/pharo/pull/7597 Fluid Class Definition ======================= ChangeGreaterThanIntoGreaterGreaterForFluidClass #7606 https://github.com/pharo-project/pharo/pull/7606 7602-preparing-fluid-syntax-changes #7603 https://github.com/pharo-project/pharo/pull/7603 7598-SpPresenter-class-does-not-display-instanceVariableNames- #7601 https://github.com/pharo-project/pharo/pull/7601 Small cleanups in FluidClassBuilder package #7577 https://github.com/pharo-project/pharo/pull/7577 Cleanup FluidClassBuilder-Tests package #7579 https://github.com/pharo-project/pharo/pull/7579 Graphics ========= Add support for mesh gradients to Athens #7546 https://github.com/pharo-project/pharo/pull/7546 Fix crashes and memory leaks in OSSDL2AthensRenderer #7543 https://github.com/pharo-project/pharo/pull/7543 Fixes ===== DNU in RubCurrentLineBarDecorator for #compose #7552 https://github.com/pharo-project/pharo/pull/7552 7582-New-Release-of-Microdown--v105 #7583 https://github.com/pharo-project/pharo/pull/7583 isClean-using-CleanBlockChecker #7540 #isClean was implemented using abstractBytecodeMessagesDo: which is slow due to trapping MessageNotUnderstood and creating messages for every bytecode. This PR adds a dedicated CleanBlockChecker that checks for the bytecodes and stops scanning as soon as it determines a block to not be clean. In addition, we move the testIsClean from OCClosureTest to BlockClosureTest and remove the example code from #isClean (the test now has that). https://github.com/pharo-project/pharo/pull/7540 Cleanup for Fonts ================== FontProviderAbstract should be renamed to AbstractFontProvider #7609 https://github.com/pharo-project/pharo/pull/7609 FontFamilyMemberAbstract should be renamed to AbstractFontFamilyMember #7611 https://github.com/pharo-project/pharo/pull/7611 FontFamilyAbstract should be renamed to AbstractFontFamily #7605 https://github.com/pharo-project/pharo/pull/7605 Cleanup FreeTypeCache #7561 https://github.com/pharo-project/pharo/pull/7561 Cleanup FreeTypeCacheLinkedList #7565 https://github.com/pharo-project/pharo/pull/7565 Remove unnecessary comment in FreeTypeCacheConstants #7563 https://github.com/pharo-project/pharo/pull/7563 Small cleanup in FontFamilyAbstract #7567 https://github.com/pharo-project/pharo/pull/7567 Cleanup FreeTypeGlyphRenderer #7559 https://github.com/pharo-project/pharo/pull/7559 Cleanup FreeTypeSubPixelAntiAliasedGlyphRenderer #7557 https://github.com/pharo-project/pharo/pull/7557 Small cleanup in FreeTypeFontProvider #7548 https://github.com/pharo-project/pharo/pull/7548 Cleanup Fonts-Abstract package #7555 https://github.com/pharo-project/pharo/pull/7555 Misc Small Cleanups ============= Cleanup ExternalType>>#cleanupUnusedTypes #7569 https://github.com/pharo-project/pharo/pull/7569 Simplify Form>>#bitsSize #7571 https://github.com/pharo-project/pharo/pull/7571 Cleanup Flashback-Decompiler-Tests package #7581 https://github.com/pharo-project/pharo/pull/7581 Simplify Socket>>#dataAvailable #7573 https://github.com/pharo-project/pharo/pull/7573 Use ifNil: in BitBlt>>#fillColor: #7575 https://github.com/pharo-project/pharo/pull/7575 Move SystemAnnouncement extensions from Calypso #7538 Calypso introduced nice methods for SystemAnnouncement like affectsMethod: , affectsClass:.

This week (43/2020) on the Issue Tracker ========================================= Roassal (Visualisations) and Graphics: -------------------------------- - Load the new version of Roassal, which is 0.9.5 https://github.com/pharo-project/pharo/pull/7461 - Do not disable freetype text hinting in Cairo #7544 https://github.com/pharo-project/pharo/pull/7544 - 7529-ImageReadWriter-should-raise-a-specialised-exception-and-not-Error #7530 https://github.com/pharo-project/pharo/pull/7530 First Class Variables ---------------------- We have now meta-objects that describe any Variable defined, be it a Global, Class Var, instance Var, temp, and others. We are continuing to refine the model and start to see where it can be used to generalise and simply. - Improve DoIt DoIts were loosing the requestor scope on the level of the AST. With that now fixed, we will be able to access variables declared by the Playground from the debugger (and highlight them correctly) These needs multiple steps to be enabled, here are two: Doit-RequestorScope #7511 https://github.com/pharo-project/pharo/pull/7511 DoIt-access-with-ReadVariable #7512 We now read temps from the context with a general "read Variable named" method, this way it will be able to read and write WorkspaceVariable instances, too: https://github.com/pharo-project/pharo/pull/7512 - The new bytecodeset has a bytecode for "push the current process". This should be exposed by the backend. To be done: show how to implement "ThisProcessVariable". CompilerBackend-pushThisProcess #7513 https://github.com/pharo-project/pharo/pull/7513 - Cleanup-referredInstVars #7541 If you look at referredInstVars, it return names of indexed instance variables. No users, no test. With First Class Variables, we can do better as soon as we need it. (we should now operate in terms of Variable *objects* not names!) https://github.com/pharo-project/pharo/pull/7541 - Variables-isTempVariable #7524 The last of the is* renamings. To be consistent with all the other is*Variable, we rename isTemp to isTempVariable (with deprecation) https://github.com/pharo-project/pharo/pull/7524 - Introduce ForeignVariable to model a unified access to variables #7527 This gives a nice perspective on what will be possible with First Class Variables: Introduce special ForeignVariable to model a unified access to variables from any context. For example it will allow us to transparently use temps from the local context in doIt expressions. (This will avoid the rewrite to ThisContext tempNamed: to access variables in a DoitIn:) https://github.com/pharo-project/pharo/pull/7527 Breakpoints =========== The improvements for Breakpoints are, too, driven by First Class Variables. e.g. Class Variables being Objects and easy to query, we can implement VariableBreakpoint for Class Variables very easily: 7421-Variable-breakpoints-do-not-work-on-class-variables #7531 https://github.com/pharo-project/pharo/pull/7531 Variables will open *many* opportunities for cleanups here... e.g. we can unify all Variable Breakpoint code to just operate on Variables. No nedd to check "if this is the name of a temp, do that, if that of an ivar, that other thing". As a first step, we did: MetaLinkResolver-simplify #7528 Use the reflective API directly to discover Variables https://github.com/pharo-project/pharo/pull/7528 VariableBreakPoint-package-merge #7542 https://github.com/pharo-project/pharo/pull/7542 Compiler ======== ScaledDecimal-readOnlyLiteral #7534 Another step for compiling literals read-only that are referred to in the source. We are just missing Boxed Floats and large Integers after this: https://github.com/pharo-project/pharo/pull/7534 CaseOf-Remove-BackendError #7517 The Design of the Opal Compiler, it was made as compatible to the old as possible. Including raising an error where it is better to fall back to just emit non-optimized code for #caseOf: https://github.com/pharo-project/pharo/pull/7517 Cleanup-headerFlagForEncoder #7518 Small cleanup of code that was just there to support the old Compiler https://github.com/pharo-project/pharo/pull/7518 Fluid Class Builder --------------- Work continuous for the Fluid Class definitions: 7515-Fix-dependencies-introduced-by-tests-of-FluidClassBuilder #7516 https://github.com/pharo-project/pharo/pull/7516 7490-definition-on-classDescription-can-be-simplified #7491 https://github.com/pharo-project/pharo/pull/7491 Cleanups/Small Fixes / Comments -------------------- And as always, we did some smaller cleanups and improvements: Add backwards compatibility Pharo9 to Pharo8 #7502 https://github.com/pharo-project/pharo/pull/7502 Fix #7507: Methods comments in Collection #7509 https://github.com/pharo-project/pharo/pull/7509 Replace Character cr asString to String cr #7526 https://github.com/pharo-project/pharo/pull/7526 Introduce symbolic platform independent name to the morphic keyDown and keyUp events #7508 https://github.com/pharo-project/pharo/pull/7508

This week (42/2020) on the Issue Tracker ================================ Debugger ======= Mostly improvements for Breakpoints this week. - Revert "Debugger-should-show-Workspace-bindings" #7452 https://github.com/pharo-project/pharo/pull/7452 - 7413-remove-breakpoint-does-not-remove-breakpoint #7496 https://github.com/pharo-project/pharo/pull/7496 - 7423-Breakpoint-on-while-nodes-do-not-work https://github.com/pharo-project/pharo/pull/7492 Spec ---- merge Spec2 0.7.4 #7493 https://github.com/pharo-project/pharo/pull/7493 - Organise and comment properly ALL widget presenters (children of SpAbstractWidgetPresenter) that are needed to create SpPresenter compositions. - Add missing examples for all widget presenters. - Presenter comments are now implemented through a microdown template, showing interesting sections and pointing to correct API to use (along with examples). - SpAbstractWidgetPresenter hierarchy now understands selectFirst. - New presenter SpTreePresenter. A tree with just one column. - SpTreeTablePresenter now understands expandPath: and expandRoots. - Added SpLinkTableColumn to add links to tables (and trees). - New utility presenter: SpListWithFilterPresenter. - Fixed alignment of cells on SpGridLayout. - SpGridLayout axis constraints now understand alignment (because sometimes you want to align a whole column, not just a cell). - Several fixes on commands for Pharo interaction. - Lots of small bugfixes. - See: https://github.com/pharo-spec/Spec/releases/tag/v0.7.4 Fluid Class Definitions -------------- This is ongoing work to have a better class definiton for what is now called "slot enabeled class defintion" (the one where one can use First Class Variables and where the Layout class is shown explicitly) 7458-Fluid-Class-integration-part-5 #7464 https://github.com/pharo-project/pharo/pull/7464 7465-Fluid-class-integration-part-6 #7466 https://github.com/pharo-project/pharo/pull/7466 7467-Fluid-class-definition-activation #7469 https://github.com/pharo-project/pharo/pull/7469 7470 fluid class a class definition can be expanded #7476 https://github.com/pharo-project/pharo/pull/7476 7472-Fluid-Class-refactor-classParser-hierarchy #7479 https://github.com/pharo-project/pharo/pull/7479 7481-testSharedSlotNodeArePolymorphicToRBVariableNodes-is-failing-in-default-image #7484 https://github.com/pharo-project/pharo/pull/7484 7473-Fluid-Class-clean-definitionWithSlotsdefinitionWithoutSlot #7485 https://github.com/pharo-project/pharo/pull/7485 Bug Fixes --------- 7500-Remove-argument-refactoring-from-Calypso-hangs-forever https://github.com/pharo-project/pharo/pull/7501 Playground-Self-Bindings #7419 https://github.com/pharo-project/pharo/pull/7419 Fix #6448 Add a way to get a FileLocator when possible instead of a FileReference #6449 https://github.com/pharo-project/pharo/pull/6449 7443-Compiling-a-method-with-a-non-declared-temps-raises-a-DNU #7450 https://github.com/pharo-project/pharo/pull/7450 Comments / Documentation ------------- Fix #7462: Enhance the help of how to use Travis #7463 https://github.com/pharo-project/pharo/pull/7463 improvement of the travis help #7506 https://github.com/pharo-project/pharo/pull/7506 CI failing tests ----------------- Skip-HiExamplesTest-testAllExamples #7442 https://github.com/pharo-project/pharo/pull/7442 Better way to design HiExamplesTest #7480 https://github.com/pharo-project/pharo/pull/7480 Cleanups -------- Cleanup-NautilusRefactoring-Shortcuts #7494 https://github.com/pharo-project/pharo/pull/7494
