An explicit goal of @benfry is to reduce class count and this PR cleans up edits made within preproc to merge supporting classes and utility functions of PdeParseTreeListener into PdeParseTreeListener itself. This includes removal of ImportUtil per https://github.com/processing/processing4/issues/10.
Some difficult to generate code is managed by the RewriterCodeGenerator and some modes may need to modify that logic. This commit makes it easier to extend parts of RewriterCodeGenerator without requiring client code to duplicate too much effort.
In response to https://github.com/processing/processing4/issues/11, allow client code to override preprocessing edit behabior by providing a subclass of PdeParseTreeListener. This does make the construction for PdePreprocessor.java a little bit messier but a builder may help and moving dependent types within enclosing classes can hopefully keep things coherent.
Refactor ANTLR message simplification infrastructure to reduce class count within preproc given @benfy feedback within https://github.com/processing/processing4/pull/1. Note that some supporting are left out but those can be further refactored behind classes as desired but strategies are all made anon or inner.
In response to @benfry feedback within https://github.com/processing/processing4/pull/1, consolidated all of the runtime path calculation into a single class while still maintaining all of the tests and caching logic. This reduces the class count but still adapts to jmod and javafx path calculation requirements for java 11.
* Move to ANTLR 4 with Java 11 lang features and localization.
Introduces ANTLR4 and Java 8 language feature support within IDE while also adding additional hooks for localization of syntax error messages, addressing https://github.com/processing/processing/issues/3054 and https://github.com/processing/processing/issues/3055.
The PR is broadly a continuation of https://github.com/processing/processing/issues/3055, bringing it up to speed with the latest Processing master plus the changes introduced at https://github.com/processing/processing/pull/5753. **Requires https://github.com/processing/processing/pull/5753 as pre-requisite.** This introduces a number of edits beyond https://github.com/processing/processing/issues/3055 beyond compatibility with current Processing master and https://github.com/processing/processing/pull/5753 including:
- Update to the grammar itself
- Change ANTLR listeners to emit `TextTransform.Edit` to unify JDT-based `PreprocessingService` and `JavaBuild`, removing code with duplicate purpose.
- Introduction of syntax error rewriting with support for localization.
- Addition of complete localized strings set for English and Spanish.
- Addition of partial localized strings set for other languages.
- Refactor of ANTLR-related code for testability and readability
- Expansion of tests including full parse tests for new Java features (type inference, lambdas).
* Ask travis for ant upgrade prior to run.
* Ask Travis for java11 update.
* Add openjdk ppa
* Travis no confirmation on add ppa.
* Force newer ant on travis.
* Swtich ant download to www-us mirror.
* Switch ant to 1.10.7
* Start x for unit tests in travis.
* More complete start x in travis.
* Revert x in travis.
* Try x in services.
Moves to Java11 and OpenJDK via AdoptOpenJDK within the processing4 train using a squash of sampottinger processing fork's java11 branch.
**Primary required changes:**
Some changes directly support OpenJFX / OpenJDK 11:
- Response to image loading changes caused by [JEP 320](https://openjdk.java.net/jeps/320)
- Use of jmodules as necessitated by [JEP 261](https://openjdk.java.net/jeps/261)
- Reponse to largely changed file paths caused by [JEP 220](https://openjdk.java.net/jeps/220).
- Modifications in build system related to AdoptOpenJDK and Java 11 which have a different naming structure for downloads.
- Allowing use of non-Oracle Java within internal Processing checks.
**Secondary required changes:**
There were some secondary required changes that impacted the usability of Processing after having moved to OpenJFX / OpenJDK 11:
- Removal of com.apple.eawt calls related to [JEP 272](http://openjdk.java.net/jeps/272)
- Response to HiDPI support on Windows and Linux in [JEP 263](https://openjdk.java.net/jeps/263)
- Removal of `java.ext.dirs`. Would be forced by [JEP 220](http://openjdk.java.net/jeps/220).
- Due to bugs on Windows, updated the JNA jars.
- Changes in downloader build tasks to support AdoptOpenJDK and OpenJFX.
- Updated org.eclipse.* / equinox jars.
- Some optimization around size of distribution.
- Update of AppBundler.
- Some changes in formulation of classpath and modifications in PreprocessingService given [JEP 261](https://openjdk.java.net/jeps/261).
**Incidental changes:**
This was (ahem) a bit of a larger PR with the above modifications. So, I wanted to introduce automated tests when possible and convenient along with a few changes for platform sustainability in order to support development:
- Addition of cross-building capability (!) made possible by AdoptOpenJDK.
- Addition of mockito for testing.
- Upgrade of junit.
- Addition of ant-contrib.
- Standardized nomenclature around JRE / JDK in `build/build.xml`
- Deduplication of code in `jre/build.xml`.
- Addition of JavaDoc in a few places.
- Some refactoring of PImage / Shape to support increased testing and readability in image manipulation code.
While sketch is running, rewriting sketch size to variables and trying to restart the sketch by pressing the play button causes PDE to freeze. Fixed by moving AWT call to EDT.
This adapter invokes all status changes on the EDT instead of worker thread of the Runner. Modifying AWT components from the worker threads may introduce strange bugs and in this case caused UI changes to run out of order, hiding runtime exceptions under problems displayed when cursor moves to the offending line.
