Package-level declarations

Types

object Dsl

Entry point for parsing .qkt DSL files.

enum KeywordCategory : Enum<KeywordCategory>

The role each lexer keyword plays in a .qkt file, for editor tooling. Every keyword the lexer recognizes (see Lexer.keywordSpellings) maps to exactly one category; ARROW is the -> punctuation kind and is not a keyword. Grammars highlight one textMateScope per category and Vim links one vimGroup per category to a stock highlight group.

Lexer

class Lexer(src: String)

Turns .qkt source into Tokens with line and column: identifiers and keywords, numbers and duration literals, quoted strings, and operators, skipping whitespace and --, # and block comments. Lexing errors throw with the offending position.

ParsedFile

sealed interface ParsedFile

Discriminates between STRATEGY and PORTFOLIO files parsed by Dsl.parseAny.

ParseError

data class ParseError(val line: Int, val col: Int, val message: String)

A single parse error with 1-based line + col coordinates pointing into the source.

Parser

class Parser(tokens: List<Token>)

Recursive-descent parser for .qkt files: turns the Lexer's tokens into a StrategyAst or a portfolio AST.

ParseResult

sealed interface ParseResult<out T>

Result of a parse: either Success with the AST or Failure with collected errors.

Token

data class Token(val kind: TokenKind, val lexeme: String, val line: Int, val col: Int)

TokenKind

enum TokenKind : Enum<TokenKind>
