The abstract syntax itself might change with each Python release; this module helps to find out programmatically what the current grammar looks like and allows modifications of it. An abstract syntax tree can be generated by passing `ast.PyCF_ONLY_AST` as a flag to the `compile()` builtin function or by using the `parse()` function from this module. The result will be a tree of objects whose classes all inherit from `ast.AST`. A modified abstract syntax tree can be compiled into a Python code object using the built-in `compile()` function. Additionally various helper functions are provided that make working with the trees simpler. The main intention of the helper functions and this module in general is to provide an easy to use interface for libraries that work tightly with the python syntax (template engines for example). :copyright: Copyright 2008 by Armin Ronacher. :license: Python License.

This is mainly useful for debugging purposes. If annotate_fields is true (by default), the returned string will show the names and the values for fields. If annotate_fields is false, the result string will be more compact by omitting unambiguous field names. Attributes such as line numbers and column offsets are not dumped by default. If this is wanted, include_attributes can be set to true. If indent is a non-negative integer or string, then the tree will be pretty-printed with that indent level. None (the default) selects the single line representation. rc sdur*d7d}d}nd}d}t|trt|}g}d}}|jD]}zt||} Wntyd}YqXYn0| durt||ddurd}qX| \} } |o| }|r|d|| fqX|| qXrh|jrh|jD]t}zt||} WntyYqYn0| durz(dump.._format..)r ASTr!_fieldsgetattrAttributeErrorappend _attributesr9 __class____name__joinr1repr) rrQprefixsepclsr6Z allsimpler7namer"simplerPannotate_fieldsinclude_attributesrG)rQrrPzsX          &zdump.._formatzexpected AST, got %rN )r)r rT TypeErrorrZr[rD)rrdrerGrrcrdumpns 0 rhcCsVdD]L}||jvr||jvrt||d}|dusDt||r|drt|||q|S)z Copy source location (`lineno`, `col_offset`, `end_lineno`, and `end_col_offset` attributes) from *old_node* to *new_node* if possible, and return *new_node*. )lineno col_offset end_linenoend_col_offsetNZend_)rYrVhasattr startswithsetattr)new_nodeZold_nodeattrr"rrr copy_locations rrcs fdd|dddd|S)a{ When you compile a node tree with compile(), the compiler expects lineno and col_offset attributes for every node that supports them.

This function may return a value which is forwarded by the `visit` method. This class is meant to be subclassed, with the subclass adding visitor methods. Per default the visitor functions for the nodes are ``'visit_'`` + class name of the node. So a `TryFinally` node visit function would be `visit_TryFinally`. This behavior can be changed by overriding the `visit` method. If no visitor function exists for a node (return value `None`) the `generic_visit` visitor is used instead. Don't use the `NodeVisitor` if you want to apply changes to nodes during traversing. For this a special visitor exists (`NodeTransformer`) that allows modifications. cCs"d|jj}t|||j}||S)z Visit a node.visit_)rZr[rV generic_visit)selfrmethodvisitorrrrvisits zNodeVisitor.visitcCsTt|D]F\}}t|tr:|D]}t|tr||qqt|tr||qdS)z9Called if no explicit visitor function exists for a node.N)r|r r1rTr)rrr{r"r}rrrrs   zNodeVisitor.generic_visitc Cs|j}tt|}|dur@tD]\}}t||r$|}q@q$|durd|}zt||}WntypYn&0ddl}| |dt d||S| |S)Nrrz" is deprecated; add visit_Constant) r"_const_node_type_namesgetr!itemsr rVrWwarningswarnDeprecationWarningr) rrr" type_namer`rarrrrrrvisit_Constants&   zNodeVisitor.visit_ConstantN)r[ __module__ __qualname____doc__rrrrrrrrs rc@seZdZdZddZdS)NodeTransformeraC A :class:`NodeVisitor` subclass that walks the abstract syntax tree and allows modification of nodes. The `NodeTransformer` will walk the AST and use the return value of the visitor methods to replace or remove the old node. If the return value of the visitor method is ``None``, the node will be removed from its location, otherwise it is replaced with the return value. The return value may be the original node in which case no replacement takes place. Here is an example transformer that rewrites all occurrences of name lookups (``foo``) to ``data['foo']``:: class RewriteName(NodeTransformer): def visit_Name(self, node): return Subscript( value=Name(id='data', ctx=Load()), slice=Constant(value=node.id), ctx=node.ctx ) Keep in mind that if the node you're operating on has child nodes you must either transform the child nodes yourself or call the :meth:`generic_visit` method for the node first. For nodes that were part of a collection of statements (that applies to all statement nodes), the visitor may also return a list of nodes rather than just a single node. Usually you use the transformer like this:: node = YourTransformer().visit(node) cCst|D]\}}t|trvg}|D]D}t|tr\||}|durFq"nt|ts\||q"||q"||dd<qt|tr||}|durt||qt|||q|Sr) r|r r1rTrrrXdelattrro)rrr{ old_valueZ new_valuesr"rprrrrs&         zNodeTransformer.generic_visitN)r[rrrrrrrrrs#rrycCs|jS)zDeprecated.
