This is primarily change to the Go target itself and its release location, which has moved to https://github.com/antlr4-go/antlr. The code still lives and this repository, but for release purposes we've created a new organization and repository so that Go users can pull versions down according to the repository and label rules

Just fixes 4.11.0 release issue. I forgot to change runtime tool version so it didn't say SNAPSHOT.

4.11.0 consist primarily:

  • a major rebuild of the Go target by Jim Idle. Please see Go target doc for more information, as it now requires the go module stuff.
  • huge internal refractoring of testing and various target speed improvements by Ivan Kochurkin
  • Getting all targets to run on all operating systems using github actions by HS.

The details by type and target follow.

ANTLR version 4.10

This is a very major release with a number of important changes. There have been many valuable contributions, but I welcome @KvanTTT and @jcking as recent "official" major ANTLR contributors. :)

WARNING: Generated 4.10 lexers and parsers are incompatible with code generated by previous versions of ANTLR. You must regenerate all of your code from grammars to use the new runtime. This is true of all targets (except probably javascript).

Repo branching structure

We have changed the branching structure of the repository. The default branch for this repo remains master and it is the latest stable release with tags for the various releases; e.g., see release tag 4.9.3. We now do development work in branch dev between releases and all pull requests should be derived from that branch. The dev branch is merged back into master to cut a release and the release state is tagged (e.g., with 4.10-rc.1 or 4.10.) Visually our process looks roughly like this:

Targets such as Go that pull directly from the repository can use the default master branch but can also pull from the active dev branch:

$ go get github.com/antlr/antlr4/runtime/Go/antlr@dev

Developers certificate of origin

In order to bring ANTLR more in line with current standard standards for contribution processes, as of 4.10, ANTLR uses the Linux Foundation's Developer Certificate of Origin, DCO, version 1.1. See file https://github.com/antlr/antlr4/raw/master/developer-cert-of-origin.txt . It is simpler than the original contributors license agreement, which required programmers to sign the contributors.txt file, which has now moved to file historical-contributors-agreement.txt .

Each commit in pull requests must have a "signature", which is simple as using -s (not -S) on the git commit command:

$ git commit -s -m 'This is my commit message'

Github's pull request process enforces the sig and gives instructions on how to fix any commits that lack the sig. See https://github.com/apps/dco for more info.

4.10-generated parsers incompatible with previous runtimes

ANTLR not only generates recursive-descent parsers; it generates a state machine called an augmented transition network (ATN) in serialized form as a bunch of integers stored in the generated parser and lexer files. This serialization format was changed for 4.10 to remove a size limit on the supported ATNs. See #3591.

The key point here is that we changed the version number stored inside the serialization format and so, in order to use this new version of ANTLR, you must regenerate all of your lexers and parsers using the 4.10 tool and then use the new runtime. Parsers generated with 4.10 or not compatible with previous versions of the runtime.

Increasing minimum java version

Going forward, we are using Java 11 for the source code and the compiled .class files for the ANTLR tool. The Java runtime target, however, and the associated runtime tests use Java 8 (bumping up from Java 7).

JavaScript target

The JS target has been substantially reworked.

Miscellaneous improvements

  • Lexer rules can use the caseInsensitive option now.
  • Improved error messages
  • We rebuilt the runtime testing rig and made continuous integration improvements; part of this was done to support more recent versions of Java
  • We cleaned up the maven pom and brought it up to date (still has errors if somebody can make a suggestion.)
