L\"owis}{martin@v.loewis.de} + +The \code{_ast} module helps Python applications to process +trees of the Python abstract syntax grammar. The Python compiler +currently provides read-only access to such trees, meaning that +applications can only create a tree for a given piece of Python +source code; generating byte code from a (potentially modified) +tree is not supported. The abstract syntax itself might change with +each Python release; this module helps to find out programmatically +what the current grammar looks like. + +An abstract syntax tree can be generated by passing \code{_ast.PyCF_ONLY_AST} +as a flag to the \function{compile} builtin function. The result will be a tree +of objects whose classes all inherit from \code{_ast.AST}. + +The actual classes are derived from the \code{Parser/Python.asdl} file, +which is reproduced below. There is one class defined for each left-hand +side symbol in the abstract grammar (for example, \code{_ast.stmt} or \code{_ast.expr}). +In addition, there is one class defined for each constructor on the +right-hand side; these classes inherit from the classes for the left-hand +side trees. For example, \code{_ast.BinOp} inherits from \code{_ast.expr}. +For production rules with alternatives (aka "sums"), the left-hand side +class is abstract: only instances of specific constructor nodes are ever +created. + +Each concrete class has an attribute \code{_fields} which gives the +names of all child nodes. + +Each instance of a concrete class has one attribute for each child node, +of the type as defined in the grammar. For example, \code{_ast.BinOp} +instances have an attribute \code{left} of type \code{_ast.expr}. + +If these attributes are marked as optional in the grammar (using a +question mark), the value might be \code{None}. If the attributes +can have zero-or-more values (marked with an asterisk), the +values are represented as Python lists. + +\subsection{Abstract Grammar} + +The abstract grammar is currently defined as follows: + +\verbatiminput{../../Parser/Python.asdl} \ No newline at end of file diff --git a/Misc/NEWS b/Misc/NEWS index f5f79e4..2cc753f 100644 --- a/Misc/NEWS +++ b/Misc/NEWS @@ -76,7 +76,7 @@ Core and builtins - A new AST parser implementation was completed.
