astviewer
Graphical User Interface for viewing Python Abstract Syntax Trees.
Installation:
First install PyQt or
PySide. 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:
>>> from astviewer.main import view
>>> view(file_name='myprog.py')
>>> view(source_code = 'a + 3', mode='eval')
