In addition to the antlr4-graps NodeJS module release there is also a new one of antlr4-vscode, the Visual Studio Code extension (see also the vscode market place). New in this version is the visual ATN graph:
A new release of the ANTLR4 grammar parsing service (antlr4-graps) NodeJS module has been published. Besides some bug fixing a big new feature was added: ATN graphs. This is something especially useful for core ANTLR4 developers (target writers or those working directly on ANTLR4) as it generates data about the internal ATN that can be visualized for a better understanding about it's structure (see also the ANTLR4 grammar support extension in vscode for such a visualization).
A few days ago I published a new release of the ANTLR4 extension for Visual Studio Code, which contains a number of fixes and new features. The light color theme is now complete as well and you get railroad diagrams for your grammar rules and even entire files. These can be saved to disk (as HTML with embedded svg), so that you can use them in other documents. Code lens support was added as well, which allows to (optionally) show rule reference counts. Hope you enjoy the new release.
Recently Sam Harwell released the ANTLR4 Typescript runtime as a Node.JS module, which opens a great way to implement ANTLR support in Node.JS modules and Visual Studio Code extensions. I took the opportunity and rewrote my antlr-graps Node.JS module and my vscode-antlr4 extension. If you are working with Visual Studio Code and want ANTLR grammar support in it then go ahead and install the extension. While it's on a good way it still cannot compete with IDEs like antlrworks2 (also written by Sam Harwell).
A few days ago Terence Parr merged the ANTLR4 C++ runtime into the main ANTLR4 repository. So it is now part of the official distribution. I had some trouble getting the runtime tests compiling on Travis CI but finally the job is done. Let's celebrate the achievement.
