v4.5-alpha002

ANTLR 4.5 C# Target Preview Release

This release is available through NuGet, with complete installation instructions described in the Readme.md.

Changes since 4.4.1-alpha001

Some non-breaking changes included in this release are not yet described in these release notes.

• This code is now based on commit fc5b7c5, which is equivalent to the 4.5-opt release.
• Breaking changes
  • The assembly strong name key and policy changed to allow library developers to more easily use ANTLR across an array of runtime environments.
  • Changed the signature of the AmbiguityInfo constructor.
  • IEdgeMap<T>.ToMap() now returns a ReadOnlyDictionary<int, T> for all runtimes.
  • DFAState.EdgeMap and DFAState.ContextEdgeMap are now ReadOnlyDictionary<int, DFAState> for all runtimes.
  • ParserRuleContext.GetTokens now returns ITerminalNode[] in all runtimes (previously .NET 4.5+ did not).
    • Note that IReadOnlyList<ITerminalNode> x = context.GetTokens(Type); will still work, because ITerminalNode[] implements IReadOnlyList<ITerminalNode> in .NET 4.5.
  • ParserRuleContext.GetRuleContexts<T>() now returns T[] in all runtimes (previously .NET 4.5+ did not).
  • The signature of generated context accessors was changed to ContextType[] in all runtimes (previously .NET 4.5+ returned IReadOnlyList<ContextType>)
  • The Func<...> delegates for runtimes prior to .NET 3.5 were moved from namespace Antlr4.Runtime.Sharpen to System.
  • The HashSet<T> class for runtimes prior to .NET 3.5 were moved from Antlr4.Runtime.Sharpen to System.Collections.Generic.

• This code is now based on the 4.2.2-opt release of ANTLR 4.

Users updating from earlier than 4.2.0-alpha001

If you are updating from a version of the C# target prior to 4.2.0-alpha001, make sure to read the release notes for 4.2.0-alpha001 as well, as several changes were made that affect the usage of this target.

v4.2.1-alpha001

ANTLR 4.2.1 C# Target Preview Release

This release is available through NuGet, with complete installation instructions described in the Readme.md.

Changes since 4.2.1-alpha001

• This code is now based on the 4.2.1-opt release of ANTLR 4.

Users updating from earlier than 4.2.0-alpha001

If you are updating from a version of the C# target prior to 4.2.0-alpha001, make sure to read the release notes for 4.2.0-alpha001 as well, as several changes were made that affect the usage of this target.

v4.2.0-alpha001

ANTLR 4.2 C# Target Preview Release

This release is available through NuGet, as described in the Readme.md.

Changes since 4.1.0-alpha003

• This code is now based on the 4.2-opt release of ANTLR 4.
• Runtime/Semantics
  • Improved support for the HIDDEN and EOF constants in the grammar. It is no longer necessary to declare these in an @members{} block in order to use them.
  • By default, the DFA will not be used for full-context parsing. This decision is due to substantial performance improvements such that the memory overhead of using the DFA for full-context parsing is no longer an obvious win. The old behavior can be enabled by setting parser.Interpreter.enable_global_context_dfa = true.
  • The lexer semantics now match the reference release of ANTLR 4, so #28 is no longer a problem.
• Build
  • Improved detection of Java for the build process.
  • Improved installation instructions.
