What's New in PyCharm 2.0

Mako & Jinja2 Templates

Mako and Jinja2 templates can be used for any PyCharm project now with syntax highlighting, code completion, formatting, quick navigation and Structure view.

The template format used in the project (Django, Mako or Jinja2) can be selected in Settings | Template Languages.

Cython

Cython is a language that allows you to write C extensions for the Python language using the familiar Python syntax.

PyCharm provides Cython support with

• Syntax highlighting, error checking and code formatting
• Context-sensitive code completion for Cython keywords, fields of structs, and attributes of extension types

  

• Code navigation and Structure view
• Quick Usages Search and refactoring tools
• Code inspections for Cython such as unresolved references detection.

  

In PyCharm you can set up an external tool for compiling your Cython code from the IDE.

Code Analysis

Reporting of parameter type mismatch errors in function calls and binary operators (when the types can be inferred, of course);

New inspection to highlight usages of deprecated modules, classes and functions.

IPython

Support for IPython in the built-in Python console

PyPy

PyCharm allows running your applications using PyPy interpreter.

Debugger

Smart Step Into action in the debugger, allowing you to select the call to step into, when the current line contains multiple method calls.

Possibility to debug applications that spawn multiple Python processes (for example, Django applications that don't run in --no-reload mode, or applications using many other Web frameworks that use a similar approach to code auto-reloading).

Updated UI

Some specific examples include: Live templates settings, Keymap Editing UI, Plugin Manager, etc.
