Early Access Program Releases

PyCharm 2019.1 EAP 7

All-new direct Jupyter Notebook editing and running support, type checking on assignment, a new JavaScript debug console, and more features are already available in this week’s Early Access Program (EAP) version of PyCharm 2019.1. Download the EAP now.

New in the EAP

Type Checking on Variable Assignment

Assignment Type Check

PyCharm already checked types passed to a function as a parameter, and returned by a function. But now we’ll also check whether or not the value you assign to a variable matches the type you’ve specified for the variable.

All-new JavaScript Debugger Console

JS Debug Console

PyCharm Professional Edition comes with all the JavaScript tools from JetBrains WebStorm. One of the new features in the current WebStorm EAP is the all new debugger console for JavaScript, which makes it easier to explore the objects in your JS code. Whether your JavaScript runs in the browser, or in Node.js, it’s now easier to explore your code.

If you’re developing with Node.js, make sure to install the Node.js plugin: go to Settings | Plugins and find the Node.js plugin from JetBrains.

Improved CSS docs

CSS Docs

Another improvement from JetBrains WebStorm: For those among us who can’t remember the correct order of every CSS shorthand property, the docs are just one press of Ctrl-Q away (Ctrl-J on macOS).

Further Improvements

  • While writing Python, have you ever written `name_of_your_list.length()`, and only realized midway that it was supposed to be `len(name_of_your_list)`? You can now use postfix completion to be done quicker. Just write `name_of_your_list.len` and press Tab to see the magic happen.

Download this EAP from our website. Alternatively, you can use the JetBrains Toolbox App to stay up to date throughout the entire EAP.

If you’re on Ubuntu 16.04 or later, you can use snap to get PyCharm EAP, and stay up to date. You can find the installation instructions on our website.

PyCharm 2019.1 is in development during the EAP phase, therefore not all new features are already available. More features will be added in the coming weeks. As PyCharm 2019.1 is pre-release software, it is not as stable as the release versions. Furthermore, we may decide to change and/or drop certain features as the EAP progresses.

All EAP versions will ship with a built-in EAP license, which means that these versions are free to use for 30 days after the day that they are built. As EAPs are released weekly, you’ll be able to use PyCharm Professional Edition EAP for free for the duration of the EAP program, as long as you upgrade at least once every 30 days.
