Wing Pro Reference Manual

Index of All Documentation »

Wing Pro Screenshot

This manual documents the entire feature set of Wing Pro, which is a Python IDE designed for professional developers.

It covers installation, customization, setting up a project, package management, editing, code warnings, refactoring, comparing files and directories, navigating source code, using the integrated Python shell, executing operating system commands, unit testing, debugging, version control, source code analysis, remote development, and extending the IDE with user-defined scripts and plugins.

Trouble-shooting information is also included, for installation and usage problems, as well as a complete reference for Wing Pro's preferences, command set, and available key bindings.

If you are looking for a gentler introduction to Wing's feature set, try the Tutorial in Wing's Help menu. A more concise overview of Wing's features is also available in the Quick Start Guide.

Our How-Tos explain how to use Wing with specific Python frameworks for web and GUI development, 2D and 3D modeling, rendering, and compositing applications, matplotlib, Raspberry Pi, and other Python-based libraries and tools.

A collection of Wing Tips, available on our website and by weekly email subscription, provides additional tips and tricks for using Wing productively.

Wing Personal and Wing 101 are free versions of Wing that omit many of the features documented here. In those Python IDEs, the Wing Manual in the Help menu is an appropriately abridged version of this manual. Compare Products
