Synopsis

Parsing modules

parseModule Source

Arguments

:: String	The input stream (python module source code).
-> String	The name of the python source (filename or input device).
-> Either ParseError Module	An error or the abstract syntax tree (AST) of the python module.

Parse a whole Python source file.

Parsing statements

parseStmt Source

Arguments

:: String	The input stream (python statement source code).
-> String	The name of the python source (filename or input device).
-> Either ParseError [Statement]	An error or maybe the abstract syntax tree (AST) of zero or more python statements.

Parse one compound statement, or a sequence of simple statements. Generally used for interactive input, such as from the command line of an interpreter.

Parsing expressions

parseExpr Source

Arguments

:: String	The input stream (python statement source code).
-> String	The name of the python source (filename or input device).
-> Either ParseError Expr	An error or maybe the abstract syntax tree (AST) of the python expression.

Parse an expression. Generally used as input for the 'eval' primitive.
