This is an experimental project to write a portable (Web + Desktop) editor in java and kotlin

This demo is designed to investigate performance limits of this approach and compare with other Web editors like Monaco and VSCode

In order to build it one need to

1. Clone and build TeaVM compiler locally:

   git clone https://github.com/konsoletyper/teavm.git
   cd teavm 
   gradle publishToMavenLocal -x test
   

2. Also, you need to get the latest emscripten for wasm compilation:

   install python from Microsoft Store
   https://apps.microsoft.com/store/detail/python-310/9PJPW5LDXLZ5
   
   git clone https://github.com/emscripten-core/emsdk.git
   cd emsdk
   ./emsdk install latest
   

   setx EMSDK D:\emsdk  
   set EMSDK D:\emsdk  
   

3. If you also need to build the desktop app, you need Microsoft Visual Studio 2022

   Do not use installer UX, there is a commandline below that installs only necessary components

   IDE: https://aka.ms/vs/17/release/vs_community.exe

   vs_community.exe --wait --p --norestart --nocache --locale en-US --add "Microsoft.VisualStudio.Workload.NativeDesktop;includeRecommended"  
   set MSBuildPath=C:\Program Files\Microsoft Visual Studio\2022\Community\Msbuild\Current\Bin\amd64
   

   If, for some reason, you do not need IDE to be installed, you can try BuildTools instead, but vs_community is recommended: BuildTools: https://aka.ms/vs/17/release/vs_BuildTools.exe
   https://learn.microsoft.com/en-us/visualstudio/install/workload-component-id-vs-build-tools?view=vs-2022

   vs_BuildTools.exe --wait --p --norestart --nocache --locale en-US --add "Microsoft.VisualStudio.Workload.VCTools;includeRecommended"  
   set MSBuildPath=C:\Program Files (x86)\Microsoft Visual Studio\2022\BuildTools\MSBuild\Current\Bin
   

4. Edit environment:

   rundll32 sysdm.cpl,EditEnvironmentVariables
   

   add the components to the user %path% manually or (not recommended) by setx command

   • MSBuild: %MSBuildPath% from step 3
   • Clang: %EMSDK%\upstream\bin from step 2

   setx Path "%Path%;%EMSDK%\upstream\bin;%MSBuildPath%" 
   

5. Finally check that compilers work, and review Environment Variables. You need a new console instance to apply env changes

   MSBuild --help
   clang --help
   

6. Clone and build TeaVM-compatible version of ANTLR:

   git clone https://github.com/pertsevpv/antlr4-teavm-compatible.git
   cd antlr4-teavm-compatible
   mvn install -DskipTests
   

   6.1. If you need to edit grammars and generate parsers, you need to install ANTLR4. The easiest way is installed antlr4-tools:

   pip install antlr4-tools
   

   Now you can build the demo with

   mvn package

7. To run desktop version one need to get libGLESv2.dll - Angle library. One way of getting it is to run org.sudu.experiments.nativelib.CopyAngleToResources You may also need to build native parts of project with this maven command: mvn package -am -pl graphics-jvm After this steps you can simply run org.sudu.experiments.DemoEditJvm

8. If you want to build ES module with its demo, you need Node.js version 18+. Steps:

   1. Run maven task to build the module (any of "a" or "b")
      1. run IDEA run-configuration "Module package"
      2. or with maven mvn package -am -pl demo-edit-es-module in root
   2. Build the webpack demo using file demo-edit-es-module/webpack-test/package.json
      1. run npm script "i"
      2. run npm script "build-editor-on-java-sample"
