PyCharm 2016.2 EAP 发布了，PyCharm是由JetBrains打造的一款Python IDE。

改进记录如下：

• Python Related Improvements

  • Function return values are now shown in the PyCharm’s debugger after stepping out from a function

  • Postfix code completion has been improved with the “main” and “print” postfix templates extracting your [expression].main and [expression].print code snippets respecting Python 2 and Python 3 versions

  • A number of fixes related to parsing requirements.txt files

• General

  • The Inspection tool window has been redesigned for better ergonomics: now code location for each of the problems is displayed along with controls to either apply a quick-fix or suppress inspection

  • More friendly popup IDE notifications in the rightmost bottom corner which are now more compact, and grouped by the subsystem they came from

  • The brand new Set Background Image option that makes your IDE look different by choosing a background image for the editor and the IDE frame

  • The installer for Windows now comes with our custom JDK build where we address some issues with focus and font rendering

•  Editor

  • Better spell-checking suggestions based on Damerau–Levenshtein distance

  • Support for font ligatures (highly voted request)

  • Coding assistance for Regex has been extended with better error reporting and added code completion for named group references

  • Language injection now works in YML files

•  Version control integration

  • The Commit dialog now shows unversioned files (so you don’t forget to commit something important)

  • Patches can now be applied from the clipboard (the IDE will offer to apply the patch when it obtains focus), or by dragging a file into the IDE

  • If a file has been moved or renamed since a patch was created for it, the IDE will try to figure that out or let you manually choose the file to apply the patch to

  • The VCS log continues getting better with a handy loading progress indicator, a shortcut to navigate to the filter field, and tooltips for graph arrows

  • The Git Log can now display commit details for several selected commits (this works for Git and Mercurial)

  • Brand new Apply Patch dialog to apply the changes from patch using a Merge-like dialog

•  Web development improvements

  • Small but neat improvements for TypeScript support

  • You can now configure whether you want IDE to add single, double or no quotes at all when autocompleting attributes in HTML and JSX

  • You can now drag a JavaScript or CSS file into the opened HTML file, and PyCharm will automatically create a script or a link tag inside the head tag for you.

  • Thanks to the integration with Angular CLI, you can now create new Angular 2 projects with ease. Install angular-cli globally via npm and create a new project in PyCharm.

  • Grunt, gulp or npm tasks as a Before launch task in a Run/Debug configuration
