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.

Full Changelog: 0.5.1...0.5.2

0.5.1

Added rudimentary support for the unity-specific #include_with_pragmas directive.

0.5.0

This is a (slight) breaking change

• Made most of the members in HLSLPrinter protected instead of private, allowing for customization of pretty printing.
• Introduced a new IdentifierNode type and use it in place of raw strings wherever the syntax tree stores identifiers. IdentifierNode can be implicitly converted to string, so most code should keep working, but this is technically a breaking change. If this breaks your code, the fix is usually simple, like changing decl.Name to decl.Name.Identifier or decl.Name.ToString().
