From eb0be361438af64467ef64f2490c48e4ce1ae86f Mon Sep 17 00:00:00 2001 From: Flavio Soibelmann Glock Date: Fri, 6 Feb 2026 11:14:34 +0100 Subject: [PATCH 01/13] Reorganize documentation for better discoverability MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## Major Changes ### New Root Files - **README.md**: Reduced from 255 to 69 lines, focus on "what" and navigation - **QUICKSTART.md**: Get running in 5 minutes with database setup emphasis - **CONTRIBUTING.md**: Comprehensive contributor guide ### Documentation Structure Reorganized docs/ into logical sections: **docs/getting-started/** - installation.md (was BUILD.md) - docker.md - oneliners.md **docs/guides/** - database-access.md (was JDBC_GUIDE.md) - emphasizes driver download - java-integration.md (new - JSR-223 guide) - module-porting.md (was PORTING_MODULES.md) - graalvm.md **docs/reference/** - feature-matrix.md (was FEATURE_MATRIX.md) - testing.md (was TESTING.md) - architecture.md (was ARCHITECTURE.md) - cli-options.md (new - command-line reference) **docs/about/** - why-perlonjava.md (was WHY_PERLONJAVA.md) - roadmap.md (from MILESTONES.md - future plans) - changelog.md (from MILESTONES.md - release history) - support.md (was SUPPORT.md) - resources.md (was RESOURCES.md) - relation-perlito.md (was RELATION_WITH_PERLITO_COMPILER.md) **docs/README.md**: Navigation guide for all docs ### Developer Documentation Reorganized dev/ structure: **dev/architecture/** - control-flow.md - block-dispatcher-optimization.md - method-call-optimization.md - inline-cache.md - large-code-refactoring.md **dev/implementation/** - pack-unpack.md (was docs/PACK_UNPACK_ARCHITECTURE.md) - regex.md - overload.md - tie.md - signal-handling.md - alarm.md **dev/maintenance/** - dependency-updates.md ### Version Updates - Updated references from Perl 5.38 to Perl 5.42 - Clarified "Java 21 or later" (not specific JDK vendor) ### Link Updates - Fixed all internal links to new paths - Updated cross-references throughout documentation ## Benefits 1. **Clear user journey**: Installation → Guides → Reference 2. **Better discoverability**: Logical grouping by purpose 3. **Shorter README**: Quick overview with clear navigation 4. **Separated concerns**: User docs vs developer docs 5. **Quick start emphasis**: Database setup warnings prominent Co-Authored-By: Claude Opus 4.6 --- .gitignore | 2 + CONTRIBUTING.md | 221 +++++++++++++ QUICKSTART.md | 181 +++++++++++ README.md | 280 +++------------- .../block-dispatcher-optimization.md} | 0 .../control-flow.md} | 0 .../inline-cache.md} | 0 .../large-code-refactoring.md} | 0 .../method-call-optimization.md} | 0 dev/{design => implementation}/alarm.md | 0 dev/{design => implementation}/overload.md | 0 .../implementation/pack-unpack.md | 0 dev/{design => implementation}/regex.md | 0 .../signal-handling.md} | 0 dev/{design => implementation}/tie.md | 0 .../dependency-updates.md} | 0 docs/README.md | 59 ++++ docs/about/changelog.md | 303 ++++++++++++++++++ .../relation-perlito.md} | 0 docs/{RESOURCES.md => about/resources.md} | 2 +- docs/about/roadmap.md | 225 +++++++++++++ docs/{SUPPORT.md => about/support.md} | 4 +- .../why-perlonjava.md} | 0 docs/{DOCKER.md => getting-started/docker.md} | 0 .../installation.md} | 0 .../oneliners.md} | 0 .../database-access.md} | 2 +- docs/{GRAALVM.md => guides/graalvm.md} | 0 docs/guides/java-integration.md | 193 +++++++++++ .../module-porting.md} | 0 .../architecture.md} | 0 docs/reference/cli-options.md | 217 +++++++++++++ .../feature-matrix.md} | 0 docs/{TESTING.md => reference/testing.md} | 0 34 files changed, 1452 insertions(+), 237 deletions(-) create mode 100644 CONTRIBUTING.md create mode 100644 QUICKSTART.md rename dev/{design/BLOCK_DISPATCHER_OPTIMIZATION.md => architecture/block-dispatcher-optimization.md} (100%) rename dev/{design/CONTROL_FLOW_IMPLEMENTATION.md => architecture/control-flow.md} (100%) rename dev/{design/INLINE_CACHE_IMPLEMENTATION.md => architecture/inline-cache.md} (100%) rename dev/{design/LARGECODE_REFACTORING.md => architecture/large-code-refactoring.md} (100%) rename dev/{design/METHOD_CALL_OPTIMIZATION_PLAN.md => architecture/method-call-optimization.md} (100%) rename dev/{design => implementation}/alarm.md (100%) rename dev/{design => implementation}/overload.md (100%) rename docs/PACK_UNPACK_ARCHITECTURE.md => dev/implementation/pack-unpack.md (100%) rename dev/{design => implementation}/regex.md (100%) rename dev/{design/signal_handling.md => implementation/signal-handling.md} (100%) rename dev/{design => implementation}/tie.md (100%) rename dev/{design/DEPENDENCY_UPDATES.md => maintenance/dependency-updates.md} (100%) create mode 100644 docs/README.md create mode 100644 docs/about/changelog.md rename docs/{RELATION_WITH_PERLITO_COMPILER.md => about/relation-perlito.md} (100%) rename docs/{RESOURCES.md => about/resources.md} (96%) create mode 100644 docs/about/roadmap.md rename docs/{SUPPORT.md => about/support.md} (96%) rename docs/{WHY_PERLONJAVA.md => about/why-perlonjava.md} (100%) rename docs/{DOCKER.md => getting-started/docker.md} (100%) rename docs/{BUILD.md => getting-started/installation.md} (100%) rename docs/{ONELINERS.md => getting-started/oneliners.md} (100%) rename docs/{JDBC_GUIDE.md => guides/database-access.md} (98%) rename docs/{GRAALVM.md => guides/graalvm.md} (100%) create mode 100644 docs/guides/java-integration.md rename docs/{PORTING_MODULES.md => guides/module-porting.md} (100%) rename docs/{ARCHITECTURE.md => reference/architecture.md} (100%) create mode 100644 docs/reference/cli-options.md rename docs/{FEATURE_MATRIX.md => reference/feature-matrix.md} (100%) rename docs/{TESTING.md => reference/testing.md} (100%) diff --git a/.gitignore b/.gitignore index 9cd0fb8bb..b2c7dfd1b 100644 --- a/.gitignore +++ b/.gitignore @@ -67,6 +67,8 @@ dev/prompts/CONTROL_FLOW_FIX_INSTRUCTIONS.md !LICENSE.md !MILESTONES.md !README.md +!QUICKSTART.md +!CONTRIBUTING.md test_*.log test_*.json diff --git a/CONTRIBUTING.md b/CONTRIBUTING.md new file mode 100644 index 000000000..26b6c4ca8 --- /dev/null +++ b/CONTRIBUTING.md @@ -0,0 +1,221 @@ +# Contributing to PerlOnJava + +We welcome contributions!

-Linux/Mac - -```bash -./jperl -E 'say "Hello World"' -``` -
- -
-Windows - -```bash -jperl -E "say 'Hello World'" -``` -
- -3. Use Perl in your Java application: - ```java - import javax.script.*; - - public class TestPerl { - public static void main(String[] args) throws Exception { - ScriptEngineManager manager = new ScriptEngineManager(); - ScriptEngine engine = manager.getEngineByName("perl"); - engine.eval("print 'Hello from Java-integrated Perl!\n'"); - } - } - ``` - -4.

Takes longer but provides comprehensive validation with detailed JSON reports. - -See [Testing Guide](docs/TESTING.md) for detailed information about: -- Test organization and categories -- Using `perl_test_runner.pl` (like `prove`) -- JUnit/Gradle integration for CI/CD -- Performance tips and debugging - -## Running the JAR File - -1. **Show Instructions**: -

Updated README.md badge and license section - Matches actual LICENSE.md content 2. **EmitterVisitor location**: Clarified architecture - EmitterVisitor (astvisitor/) coordinates bytecode generation - Emit* classes (codegen/) generate actual JVM bytecode - Matches CLAUDE.md description 3. **Test structure**: Corrected perl5_t/ location - perl5_t/ is at project root, not in src/test/resources/ - Created by dev/import-perl5/sync.pl script - Contains perl5_t/t/ (core tests) and perl5_t/[Module]/ (module tests) 4. **sync.pl description**: Made clearer - Explained that sync.pl reads config.yaml - Copies from perl5/ (Perl 5 source) to perl5_t/ - Applies patches from dev/import-perl5/patches/ 5. **GraalVM docs**: Moved to dev/ directory - Moved docs/guides/graalvm.md to dev/graalvm.md - Removed from user-facing guides (experimental feature) - Updated navigation in README.md and docs/README.md 6. **MILESTONES.md**: Converted to redirect stub - Reduced from 523 lines to 21 lines - Points to docs/about/roadmap.md (future plans) - Points to docs/about/changelog.md (release history) - Eliminates duplicate content ## Files Changed - README.md - License badge and text corrected - CONTRIBUTING.md - Architecture and test structure clarified - MILESTONES.md - Now a redirect stub - docs/reference/testing.md -

Track progress and catch regressions over time **Features documented:** - Clean process (killall java, rm tmp files) - Extended timeout for comprehensive tests (--timeout 300) - Timestamped log format (YYYYMMDD_HHMMSS) - Comparing before/after test runs - Log organization strategy **Use cases:** - Before/after feature implementation - Daily progress tracking - Identifying when regressions were introduced - Measuring optimization impact This documents the actual developer workflow for tracking test suite improvements during feature development and debugging.
