Overview ¶
Package parser implements a parser for Go source files. Input may be provided in a variety of forms (see the various Parse* functions); the output is an abstract syntax tree (AST) representing the Go source. The parser is invoked through one of the Parse* functions.
The parser accepts a larger language than is syntactically permitted by the Go spec, for simplicity, and for improved robustness in the presence of syntax errors. For instance, in method declarations, the receiver is treated like an ordinary parameter list and thus may contain multiple entries where the spec permits exactly one. Consequently, the corresponding field in the AST (ast.FuncDecl.Recv) field is not restricted to one entry.

Functions ¶
func MakeQuote ¶
func MakeQuote(p_or_nil *parser, op token.Token, pos token.Pos, node ast.Node) (*ast.UnaryExpr, *ast.BlockStmt)
MakeQuote creates an ast.UnaryExpr representing op{node}: usually one of quote{node}, quasiquote{node}, unquote{node} or unquote_splice{node}. Returns both the unaryexpr and the blockstmt containing its body
Types ¶
type Mode ¶
type Mode uint
A Mode value is a set of flags (or 0). They control the amount of source code parsed and other optional parser functionality.
const ( PackageClauseOnly Mode = 1 << iota // stop parsing after package clause ImportsOnly // stop parsing after import declarations ParseComments // parse comments and add them to AST Trace // print a trace of parsed productions DeclarationErrors // report declaration errors SpuriousErrors // same as AllErrors, for backward-compatibility CopySources // copy source code to FileSet AllErrors = SpuriousErrors // report all errors (not just the first 10 on different lines) )
