0.10.0

• Removed trailing trivia concept from Token, leaving only leading trivia, as suggested in #13. This is a breaking change for users of 0.9.0.
• Fixed a bug where tokens in embedded HLSL blocks in ShaderLab shaders would have incorrect Position when using PreProcessorMode.DoNothing.

0.9.0

• Preserve comments in the syntax tree by adding a "trivia" concept inspired by Roslyn. Comments will be attached to nearby tokens, and accessibly via Token.LeadingTrivia and Token.TrailingTrivia.
• Added some helpers to HLSLSyntaxFacts for querying info about texture types.
• Fix bug in parsing of samplerCUBE declarations.

0.8.0

• Added a flag that can be used to prevent automatically attempting to include 'UnityCG.cginc' before CGPROGRAM blocks. This flag is called ShaderLabParserConfig.IncludeProgramBlockPreamble
• Made the preprocessor more configurable, by converting PreProcessorMode to a bitflag. You can use this to enable and disable various parts of the preprocessor logic. This is a minor breaking change.

0.7.0

• Changed the arguments to AttributeNode to be of type ExpressionNode rather than LiteralExpressionNode. This allows the parser to handle attributes like [numthreads(1+1, 2, 3)]. This is a minor breaking change.
• Added [DebuggerStepThrough] to most methods in HLSLSyntaxVisitor and ShaderLabSyntaxVisitor. This should make stepping through visitor implementations with a debugger less painful.
• Fixed a bug where compound declarations like int a = 3, b = 4; were parsed incorrectly. (#11)
• Fixed a bug where scientific float literals were being incorrect parsed as integers.
• Added support for char variable declarations.
• Fixed a null reference exception when passing no tokens to the constructor for HLSLSyntaxNode.

0.6.2

Bugfix: ParseStatements wasn't working due to an inverted loop condition.

0.6.1

Full Changelog: 0.6.0...0.6.1

• Added support for PackageRequirements blocks in ShaderLab code (https://docs.unity3d.com/Manual/SL-PackageRequirements.html)
• Fixed a small bug in the printing of ColorMask in ShaderLabPrinter.
• Add newlines after program blocks in ShaderLabPrinter.

0.6.0

This release contains breaking changes

Full changeset: 0.5.4...0.6.0

Changes:

• Feature: Added ShaderLabPrinter, which can be used to pretty-print ShaderLab syntax trees. There is also a new helper function ShaderLabSyntaxNode.GetPrettyPrintedCode that invokes it.
• Feature: Added support for the stringizing (#) operator in the embedded HLSL preprocessor.
• Breaking: Allowed for disambiguating CG, HLSL and GLSL program blocks. TokenKind.ProgramBlock and TokenKind.IncludeBlock have been removed in favor of specialized variants like TokenKind.HlslProgramBlock. HLSLProgramBlock and HLSLIncludeBlock have a new field Kind which describes which kind of code the block represents.
• Breaking: Marked ShaderPassNode, ShaderLabCommandNode and ShaderLabBasicToggleCommandNode as abstract, and remove their associated methods from ShaderLabSyntaxVisitor. These AST nodes don't provide additional info, and having them as concrete classes was confusing.
• Add some more helper functions to ShaderLabSyntaxFacts.
• Fixed a bug where ShaderLabParser would occasionally get stuck in an infinite loop.
• Added newlines between function attributes when using HLSLPrinter.
• Added a type-erased version of PrintingUtil.GetEnumName, called PrintingUtil.GetEnumNameTypeErased.

0.5.4

• Fix bug where character and string literals aren't printed correctly #6
• Fix expansion of recursively defined/delayed function-like macros #7

Thanks @pashanhenlei

0.5.3

Fix a bug where mul-assign (*=) was parsed as a single asterisk (*). Thanks to @pashanhenlei for spotting.

0.5.2

Fix bug where floating point literals using scientific notation with positive exponent were not parsed correctly.
