astviewer
=========
Graphical User Interface for viewing Python Abstract Syntax Trees.
### Installation:
First install [PyQt](https://www.riverbankcomputing.com/software/pyqt/download5) or
[PySide](http://wiki.qt.io/Category:LanguageBindings::PySide::Downloads). Either one is fine,
AstViewer automatically detects which Qt bindings are installed. If both bindings are installed
it prefers PyQt over PySide (You can force AstViewer to use a certain binding by setting the
`QT_API` environment variable to `pyqt5`, `pyqt4`, `pyside` or `pyside2`.)
If you are using the Anaconda Python distribution it is recommended to install PyQt as follows:
%> conda install pyqt
or, for PySide use
%> conda install pyside2
If you are *not* using the Anaconda Python distro, you can install the dependencies with Pip as follows:
%> pip3 install pyqt5
or
%> pip install pyside2
There is no conda recipe for the AstViewer, but you can use Pip to install it even if you use
Anaconda. To install it type:
%> pip install astviewer
### Usage:
Command line example:
%> pyastviewer myprog.py
Examples to use from within Python:
```python
>>> from astviewer.main import view
>>> view(file_name='myprog.py')
>>> view(source_code = 'a + 3', mode='eval')
```

The [Green Tree Snakes documentation on ASTs](http://greentreesnakes.readthedocs.org/) is available
for those who find the [Python ast module documentation](http://docs.python.org/3/library/ast) too brief.
