sourcecodegen 0.6.4

A Python source-code generator based on the ``compiler.ast`` abstract syntax tree.

Overview

This package provides a module-level source-code generator which operates on the AST from the built-in compiler.ast module.

Note that this AST is not compatible with the new ast module in Python 2.6.

Usage

The generator works on AST parse trees.

>>> from compiler import parse
>>> tree = parse("""\
...     print 'Hello, world!'
... """)

We can now generate Python-code equivalent to the original using the source-code generator.

>>> from sourcecodegen import ModuleSourceCodeGenerator
>>> generator = ModuleSourceCodeGenerator(tree)
>>> print generator.getSourceCode()
print 'Hello, world!'

Changelog

0.6.4 (released 24/01/2009)

• Added convenience method to generate code. [malthe]

0.6.3 (released 18/12/2008)

• Allow proper operation under Python 2.4 (try/finally fixes). [chrism]

0.6.2 (released 14/12/2008)

• Fixed issue where lambda blocks would be incorrectly indented; also, function bodies are now always properly cleared. [malthe]

0.6.1 (released 13/12/2008)

• Fixed issue where generators would not be prioritized in certain cases. [malthe]

0.6 (released 13/12/2008)

• Operator precedence is now taken into account such that we can avoid unnecessary use of parentheses. This is done not only for aesthetic reasons, but more importantly to avoid running into parser errors due to Python’s nesting limitation. [malthe]

0.5 (released 28/11/2008)

• Added yield and unary operators. [malthe]

0.4 (released 28/11/2008)

• Make sure all binary operators get parentheses around them; we may be able to improve upon this in the future (for legibility-reasons). [malthe]

0.3 (released 27/11/2008)

• Added logical operators. [malthe]

• Fixed tuple unpacking issues. [malthe]

• Added for-loop. [malthe]

0.2 (released 27/11/2008)

• Fixed issue with tuples and parentheses. [malthe]

• Fixed issue with multiple assignments. [malthe]

• Added support for not operator. [malthe]

• Fixed issue where default arguments would be written incorrectly if no non-keyword arguments were present. [malthe]

• Fixed issue where statements would not be cleared properly. [malthe]

• Assignments are statements and should terminate. [malthe]

0.1 (released 26/11/2008)

• Initial release.
