Overview

The IDL parser reads IDL files for the Babel tools. IDL files describe models and web services. The parser package uses Go's built-in lexical analyzer and Go's YACC tool to parse IDL files. The result is placed into the structures defined in the idl package.

For more information, see the README.md file.

Functions

func ParseIdl

func ParseIdl(fileName, lang string) (*idl.Idl, error)

ParseIdl parses the idl in the given file with tests for the given language. The Idl object is returned unless an error occured.

Types

type IdlLex

type IdlLex struct {
	Filename string
	Errors   []string
	// contains filtered or unexported fields
}

IdlLex is a lexer usable by yacc that uses Go's built-in lexer to provide lexical analysis for IDL files.

func (*IdlLex) Error

func (lex *IdlLex) Error(s string)

Error is called when a parsing error occcurs. Errors are collected in an array.

func (*IdlLex) Init

func (lex *IdlLex) Init(src io.Reader, fname string)

Init prepares the lexer for use.

func (*IdlLex) Lex

func (lex *IdlLex) Lex(yylval *yySymType) int

Lex returns the next token in the steam and classifies it.
