Overview

Package ast provides TTCN-3 syntax tree nodes and functions for tree traversal.

Package parser implements a tolerant TTCN-3 parser library.

It implements most of TTCN-3 core language specification 4.10 (2018), Advanced Parametrisation, Behaviour Types, Performance and Realtime Testing, simplistic preprocessor support, multi-line string literals for Titan TestPorts, and optional semicolon for backward compatibility.

Constants

View Source 
const (
	PedanticSemicolon = 1 << iota // expect semicolons pedantically
	IgnoreComments                // ignore comments
	Trace                         // print a trace of parsed productions
)

const (
	LowestPrec  = 0 // non-operators
	UnaryPrec   = 6
	HighestPrec = 15
)

A set of constants for precedence-based expression parsing. Non-operators have lowest precedence, followed by operators starting with precedence 1 up to unary operators. The highest precedence serves as "catch-all" precedence for selector, indexing, and other operator and delimiter tokens.

The list of tokens.

func Lookup added in v0.18.0 

func Lookup(ident []byte) Kind

Lookup maps an identifier to its keyword token or IDENT (if not a keyword).

func (Kind) IsKeyword 

func (tok Kind) IsKeyword() bool

IsKeyword returns true for tokens corresponding to keywords; it returns false otherwise.

func (Kind) IsLiteral 

func (tok Kind) IsLiteral() bool

IsLiteral returns true for tokens corresponding to identifiers and basic type literals; it returns false otherwise.

func (Kind) IsOperator added in v0.18.0

func Parse 

func Parse(src []byte, opts ...ParserOption) (root *Root, names map[string]bool, uses map[string]bool)

Parse the source code of a single file and return the corresponding syntax tree. The source code may be provided via the filename of the source file, or via the src parameter.

If src != nil, Parse parses the source from src and the filename is only used when recording position information. The type of the argument for the src parameter must be string, []byte, or io.Reader. If src == nil, Parse parses the file specified by filename.

The mode parameter controls the amount of source text parsed and other optional parser functionality.

If the source couldn't be read, the returned AST is nil and the error indicates the specific failure. If the source was read but syntax errors were found, the result is a partial AST (with Bad* nodes representing the fragments of erroneous source code). Multiple errors are returned via a ErrorList which is sorted by file position.
