Highlights

Interpreter settings

Now it is easier to create an environment for your project and set up all the dependencies at once.
When you clone a project from the repo, PyCharm checks if there is a requirements.txt, setup.py, environment.yml, or pipfile inside it. If there is, the IDE suggests per-project environment creation based on the detected files.

If you skip the environment creation at this step, autoconfiguration will still be available in the editor itself.

Inverting an “if” statement

Now you can easily invert “if” statements and switch them back in PyCharm. Kudos to Vasya Aksyonov, who contributed this feature to our open-source PyCharm Community Edition.

Go to the context menu for “if”, choose Show Context Actions, and then select “Invert ‘if’ condition”. The condition of the “if” statement will be inverted and the branches will switch places, preserving the initial semantics of the code.

invert_if

When there is an “if” statement without an “else”, then after it has been inverted a “pass” will be created for the “if” that was inverted and an “else” clause will be added to the statement.

early_return

This feature works for all “if” statements without “elif” branches. The action also understands control flow, and can handle things like early return, producing sensible code.

VCS

We’ve added a Git tab to the Search Everywhere dialog. In it you can find commit hashes and messages, tags, and branches.

Create a React component from its usage

As you might know, PyCharm constantly checks that referenced variables and fields are valid. When they aren’t, in many cases it can suggest creating the relevant code construct for you. Now it can do this for React components, too. Place the caret at an unresolved component, press Alt+Enter, and then select the corresponding inspection. And you’re done!

Plugins enabled per project

We have taken plugin customization one step further. In Settings | Preferences / Plugins, the drop-down list next to the plugin name has been replaced with a new gear icon that has all the activation options. You can enable the plugin just for the current project or for all of them by selecting Enable for Current Project or Enable for All Projects.

Reader Mode

To make reading comments easier, we’ve implemented Reader Mode for read-only files and files from External Libraries. We’ve added a nicer display for font ligatures, code vision hints with the number of usages, and more. To configure the new mode, go to Preferences | Settings / Editor / Reader Mode.
