Package Loyc.Syntax.Les

Contains classes related to Loyc Expression Syntax (LES), including the parser and printer (reachable through Loyc.Syntax.Les.LesLanguageService). More...

Classes
struct	CustomLiteral
	A custom literal is a normal number or string paired with a (typically unrecognized) type prefix or suffix. More...
interface	INodePrinterWriter
	This interface is implemented by helper objects that handle the low-level details of node printing. It is used by Les2Printer. More...
class	Les2LanguageService
	The Value property provides easy access to the lexer, parser and printer for Loyc Expression Syntax (LES). More...
class	Les2Lexer
	Lexer for EC# source code. More...
class	Les2Parser
	Parses LES (Loyc Expression Syntax) code into a sequence of Loyc trees (LNode), one per top-level statement. More...
class	Les2PrecedenceMap
class	Les2Printer
	Prints a Loyc tree in LES (Loyc Expression Syntax) format. More...
class	Les2PrinterOptions
	Options to control the way Loyc trees are printed by Les2Printer. More...
class	Les3LanguageService
class	Les3Lexer
class	Les3Parser
class	Les3PrecedenceMap
	This class's main job is to maintain a table of Precedence values for LES operators. When you ask about a new operator, its precedence is chosen by this class and cached for future reference. More...
class	Les3PrettyPrinter
	A variant of Les3Printer that adds syntax highlighting in one of three ways: as console output, as HTML output, or as LesColorCode control codes. More...
class	Les3Printer
class	Les3PrinterOptions
	A set of extended options supported when printing in LES3. More...
class	LesLanguageService
	Alternate name for Les2LanguageService (will change to Les3LanguageService in the future) More...
class	LesPrecedence
	Contains Precedence objects that represent the precedence levels of LES. More...
class	NodePrinterWriterBase
	Abstract base class for INodePrinterWriter. Has an protected _indentLevel field that is increased by Indent() and decreased by Dedent(). More...
class	TokenExt
	Provides the Type() extension method required by Token and the ToString(Token) method to express an LES token as a string, for tokens that contain sufficient information to do so. More...

Typedefs
using	TT = TokenType
using	S = CodeSymbols
using	P = LesPrecedence

Enumerations

	These codes are produced as control characters (i.e. cast to char) in the output of Les3PrettyPrinter. More...

Detailed Description

Contains classes related to Loyc Expression Syntax (LES), including the parser and printer (reachable through Loyc.Syntax.Les.LesLanguageService).

Enumeration Type Documentation

enum Loyc.Syntax.Les.LesColorCode

These codes are produced as control characters (i.e. cast to char) in the output of Les3PrettyPrinter.

A note about implementation coupling: Les3PrettyPrinter relies on color codes provided to it by the base class Les3Printer.
