We require Xcode 9 for the Swift target, and the C++ and .NET tests shouldn't care either way. We no longer need to install cmake: this is already in the Travis Xcode 9.0 image (and it barfs if we try to install it again). We no longer need the rvm bug workarounds; a newer version of rvm is in the Xcode 9.0 image so this is no longer a problem. The openssl package is already installed and up-to-date now, so there is no need to install that. These changes mean that we don't need before-install-osx-cpp.sh or before-install-os-swift.sh at all, and before-install-osx-dotnet.sh gets a bit shorter. .travis.yml gets a small change to handle the fact that some platform / target combos don't need before-install any more. |

ANTLR v4
ANTLR (ANother Tool for Language Recognition) is a powerful parser generator for reading, processing, executing, or translating structured text or binary files. It's widely used to build languages, tools, and frameworks. From a grammar, ANTLR generates a parser that can build parse trees and also generates a listener interface (or visitor) that makes it easy to respond to the recognition of phrases of interest.
Given day-job constraints, my time working on this project is limited so I'll have to focus first on fixing bugs rather than changing/improving the feature set. Likely I'll do it in bursts every few months. Please do not be offended if your bug or pull request does not yield a response! --parrt

The Definitive ANTLR 4 Reference
Programmers run into parsing problems all the time. Whether it’s a data format like JSON, a network protocol like SMTP, a server configuration file for Apache, a PostScript/PDF file, or a simple spreadsheet macro language—ANTLR v4 and this book will demystify the process. ANTLR v4 has been rewritten from scratch to make it easier than ever to build parsers and the language applications built on top. This completely rewritten new edition of the bestselling Definitive ANTLR Reference shows you how to take advantage of these new features.
You can buy the book The Definitive ANTLR 4 Reference at amazon or an electronic version at the publisher's site.

Additional grammars
This repository is a collection of grammars without actions where the root directory name is the all-lowercase name of the language parsed by the grammar. For example, java, cpp, csharp, c, etc...
