Types ¶
type DiagCode ¶
type DiagCode string
DiagCode identifies the kind of parse diagnostic.
const ( // Structural errors DiagUnexpectedToken DiagCode = "E001" // unexpected token DiagExpectedToken DiagCode = "E002" // expected specific token DiagBadIndentation DiagCode = "E003" // indentation mismatch DiagUnterminatedStr DiagCode = "E004" // unterminated string literal // Declaration errors DiagDuplicateDecl DiagCode = "E010" // duplicate declaration name DiagReservedName DiagCode = "E011" // use of reserved name (done/fail) as declaration DiagUnknownProperty DiagCode = "E012" // unknown property in a node block DiagMissingProperty DiagCode = "E013" // required property missing // Value errors DiagInvalidValue DiagCode = "E020" // invalid value (e.g. bad session mode) DiagInvalidType DiagCode = "E021" // invalid type expression )
type Diagnostic ¶
type Diagnostic struct {
Code DiagCode
Severity Severity
Message string
File string
Line int // 1-based
Column int // 1-based
}
Diagnostic represents a positioned parse error or warning.
func (Diagnostic) Error ¶
func (d Diagnostic) Error() string
type Lexer ¶
type Lexer struct {
// contains filtered or unexported fields
}
Lexer tokenizes an iterion DSL source file with indent-sensitive INDENT/DEDENT tokens.
type ParseResult ¶
type ParseResult struct {
File *ast.File
Diagnostics []Diagnostic
}
ParseResult is the output of Parse.
func Parse ¶
func Parse(filename, src string) *ParseResult
Parse parses an iterion DSL source file and returns the AST and any diagnostics.
type Token ¶
type Token struct {
Type TokenType
Value string // raw text of the token
Line int // 1-based
Column int // 1-based
}
Token is a single lexical token produced by the lexer.
type TokenType ¶
type TokenType int
TokenType identifies the kind of a lexical token.
const ( // Special TokenEOF TokenType = iota TokenError // lexer error TokenIndent // virtual: indentation increase TokenDedent // virtual: indentation decrease // Literals TokenIdent // identifier TokenString // "..." string literal TokenInt // integer literal TokenFloat // float literal TokenPromptLine // raw prompt body line // Punctuation TokenColon // : TokenArrow // -> TokenEquals // = TokenComma // , TokenLBrack // [ TokenRBrack // ] TokenLBrace // { TokenRBrace // } TokenLParen // ( TokenRParen // ) TokenDot // .
