./devel/py-astor, Read/rewrite/write Python ASTs

[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ] [ Add to tracker ]


Branch: CURRENT, Version: 0.8.1nb1, Package name: py39-astor-0.8.1nb1, Maintainer: pkgsrc-users

astor is designed to allow easy manipulation of Python source via the AST. There
are some other similar libraries, but astor focuses on the following areas:

* Round-trip back to Python via Armin Ronacher's codegen.py module:
** Modified AST doesn't need linenumbers, ctx, etc. or otherwise be directly
compileable
** Easy to read generated code as, well, code
* Dump pretty-printing of AST
** Harder to read than round-tripped code, but more accurate to figure out
what is going on.
** Easier to read than dump from built-in AST module
* Non-recursive treewalk
** Sometimes you want a recursive treewalk (and astor supports that, starting
at any node on the tree), but sometimes you don't need to do that. astor
doesn't require you to explicitly visit sub-nodes unless you want to:
** You can add code that executes before a node's children are visited,
and/or
** You can add code that executes after a node's children are visited, and/or
** You can add code that executes and keeps the node's children from being
visited (and optionally visit them yourself via a recursive call)
** Write functions to access the tree based on object names and/or attribute
names
** Enjoy easy access to parent node(s) for tree rewriting

Log message:
py-astor: updated to 0.8.0

0.8.0:

New features
Support ast.Constant nodes being emitted by Python 3.8 (and initially created in \ 
Python 3.6).
Support Python 3.8's assignment expressions.
Support Python 3.8's f-string debugging syntax.
:func:astor.to_source now has a source_generator_class parameter to customize \ 
source code generation.
The :class:~SourceGenerator class can now be imported from the :mod:astor \ 
package directly. Previously, the astor.code_gen submodule was needed to be \ 
imported.
Support Python 3.8's positional only arguments. See PEP 570 for more details.

Bug fixes
Fix string parsing when there is a newline inside an f-string.
Fixed code generation with escaped braces in f-strings.
Fixed code generation with attributes of integer literals, and with u-prefixed \ 
string literals.
Fixed code generation with very large integers.
Fixed :class:astor.tree_walk.TreeWalk when attempting to access attributes \ 
created by Python's type system (such as __dict__ and __weakref__)

Log message:
py-astor: updated to 0.6

0.6:

New features
* New astor.rtrip command-line tool to test round-tripping of Python source to \ 
AST and back to source. (Contributed by Patrick Maupin.)
* New pretty printer outputs much better looking code:
  . Remove parentheses where not necessary
  . Use triple-quoted strings where it makes sense
  . Add placeholder for function to do nice line wrapping on output
* Additional Python 3.5 support: - Additional unpacking generalizations (PEP 448)
  .  Async and await (PEP 492)
* Added Python 3.6 feature support:
  . f-strings (PEP 498)
  . async comprehensions (PEP 530)
  . variable annotations (PEP 526)
* Code cleanup, including renaming for PEP8 and deprecation of old names. See \ 
:ref:`deprecations` for more information.

Bug fixes
* Don't put trailing comma-spaces in dictionaries. astor will now create \ 
{'three': 3} instead of {'three': 3, }.
* Fixed several bugs in code generation.
