RText is a programmer's text editor written in Java. It has all the features you would expect:

• Syntax highlighting for 40+ languages
• Code folding
• Regex search and replace
• Find/replace in files
• Varying degrees of code completion for C, Java, Perl, JavaScript, and more
• Varying degrees of syntax checking for various languages (JSHint integration for JavaScript, compiler checking for Perl, XML well-formedness checking, etc.)
• Programmatic macros, write them in either JavaScript or Groovy
• Application lifecycle (bootstrap, plugin loading, cleanup, shutdown)
• Preference loading and saving
• User-configurable key bindings
• Standard modals for Options, Help, About, Printing
• File chooser (richer feature set and improved usability over JFileChooser)
• Dockable windows
• External tools
• Much more

RText uses Gradle to build. To compile, run all unit tests, and create the jar, and run:

./gradlew build installDist
java -jar build/install/rtext/RText.jar

Note that RText requires Java 11 or later to build.

To create the Windows version of the application, run the generateWindowsStarterExe task in addition to installDist. This ensures a trimmed-down JRE is generated, and a starter RText.exe file is added into build/install/rtext:

./gradlew build installDist generateWindowsStarterExe

The generateWindowsStarterExe task uses a JDK 11 install and launch4j as defined in gradle.properties.

After building the installable image, you can create the win32 installer by running the MakeRTextInstaller.nsi NSIS script at the root of the project.

Building the OS X package is a little wonky at the moment. I am working on finding the best way to build an App bundle via Gradle. It doesn't seem like there is a good way to do it as of Java 11+. Previously, the easiest way to do so was:

./gradlew clean build installDist
vi build.gradle
<un-comment the macAppBundle plugin at the top and config at the bottom>
./gradlew createApp
cp -R ./build/install/rtext ./build/macApp/RText.app/Contents/
mv ./build/macApp/RText.app/Contents/rtext ./build/macApp/RText.app/Contents/Java

This used to create a functional RText.app, but note the application icon is not correct yet.
