Highlights

Code With Me

PyCharm EAP 2020.3 now includes Code with Me features by default. If you are practicing pair programming or teaching Python online, it is definitely a tool you will fall in love with.

As a host you can define the level of permissions you want to grant to your guest users. You can allow others to edit files, access the terminal, and run code in your project. Alternatively, you can limit their access level to only viewing what happens while you are live coding.

Apart from the ability to develop collaboratively, a notable feature of Code With Me is its support of code insight features on the guest side, such as code navigation and autocompletion.

Learn more about Code With Me features in this blog post.

Grazie

Grazie provides intelligent spelling and grammar checks for text that you write in PyCharm. It recognizes natural language constructs in programming languages (Python, Java, and others), markup languages (Latex, Markdown, XML, and HTML), comments, commit messages, and more.

Grazie can help you check grammar in your text files (for example in README.md). To get the most out of it, you can also configure it to check textual elements in your source code such as string literals, comments, or commit messages.

Grazie is set to check English text by default, and you can enable over 15 other languages, including German, Russian, Chinese, and others, by opening Settings/Preferences and selecting Editor > Proofreading.

NOTE: All verification is performed locally, inside your IDE.

Learn more about Grazie’s functionality in the PyCharm Web Help.

Web development

Tailwind CSS plugin

PyCharm 2020.3 now supports the Tailwind CSS plugin. Enjoy autocompletion of Tailwind classes in your HTML files and after the @apply directive. You can make customizations using tailwind.config.js files and get autocompletion for them too.

All you need to do is install the plugin from Settings/Preferences|Plugins|Marketplace > Tailwind CSS.

Notable fixes

• Plots layouts in SciView are now displayed correctly.
• Fixed issue with types and parameters not being shown in code completion popup inside the Python Console.
• We’ve implemented easy navigation through the error path within a project for webpack.

Let’s Celebrate PyCharm’s 10th!

PyCharm is celebrating its 10th anniversary. Over the last decade, PyCharm has grown alongside Python, carefully following changes in the language and adjusting to the feedback of Python developers. This whole time, the PyCharm team has spared no effort to make PyCharm more enjoyable and productive for its users to work with.

Looking back, we can clearly see that PyCharm is not just a purely commercial product – it’s also the result of community-driven development. Our users have contributed immensely to making PyCharm better through all these years.

We are proud of the work made up to these days, and prepared PyCharm birthday page with a special ‘thank you’ message to our users, as well as a timeline with important milestiones, and a challenge.

The Podcast

If you feel more like listening to a story than reading it, a nice way to understand where PyCharm comes from is to listen to the latest episode of the Early Access PyCharm Podcast by our developer advocate Nafiul Islam, with one of the PyCharm originators, Dmitry Jemerov. Dmitry shares why PyCharm was created in the first place, and more importantly, why we released PyCharm Community Edition (spoiler: Dmitry loved Python so much that he wanted Python developers to have proper tooling, even if they were just beginning to learn Python).

The Challenge

As we celebrate PyCharm’s 10th anniversary, we want to thank every single PyCharm user and Python developer. You all helped us to get this far, so we think this is the perfect time to put the spotlight on you.

We are looking for 10 the most groundbreaking projects created with PyCharm in the last 10 years so we want to invite you to share the Python project that you are created using PyCharm, and vote for other projects in our showcase.

You can submit your projects in this Twitter thread until the 20th of November, then we will announce the shortlist so the community can vote. The 10 projects with the most votes will be awarded the title PyCharm Project of the Decade, and their authors will receive limited edition hoodies.

SUBMIT A PROJECT

Thank you all for using PyCharm. It has been a great decade and we look forward to the next one! Check out PyCharm’s 10th anniversary birthday page for all celebration details.

PyCharm 2020.3 EAP #3

The third build of PyCharm 2020.3 is now available in the Early Access Program with features and fixes for a smoother, more productive experience.

We invite you to join our EAP to try out the latest features we have coming up, test that they work properly in your environments, and help us make a better PyCharm for everyone!

DOWNLOAD PYCHARM 2020.3 EAP

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.

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.

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.

Learn more.

VCS

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

Web development

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.

Other updates

• PyCharm now supports the Couchbase Query service.
• The Concurrency Diagram button is now moved to the Profiler Executors group panel in the top right-hand corner of the editor.
• PyCharm now recognizes Python 3.10. Yes, we are already getting ready for it!

Notable fixes

The problem that caused copying the prompt together with the code when copying multiline commands is now fixed.

Datalore by JetBrains: Online Jupyter Notebooks Editor With PyCharm’s Code Insight

If you work with Jupyter Notebooks and want to run code, produce heavy visualizations, and render markdown online – give Datalore a try. It comes with cloud storage, real-time collaboration, notebook publishing, and PyCharm’s code insight. In this blog post we’ll give you a quick introduction to what you can do in Datalore.

Try Datalore

Jupyter notebooks in the cloud

Once you register a Datalore account, you can get your first notebook up and running in seconds. No setup is required, and the most popular data science libraries such as NumPy, Matplotlib, pandas, TensorFlow, etc., are already preinstalled.

As soon as you create a new notebook or upload an existing one, you can attach dataset files to it. In Datalore, files are uploaded to cloud storage and then attached to the notebook. The free Datalore plan comes with 10 GB of storage space.

Code insight in Datalore

One of the best features of Datalore is its coding assistance, which it borrows directly from PyCharm.

We firmly believe that code completion, quick-fixes, auto-imports, rename, and reformatting options help make your online coding experience far more productive. Try out the coding assistance and let us know what you think!

Online editor experience

Datalore supports Markdown and LaTeX. All computations are run in the cloud, which improves the time it takes for visualizations and markdown cells to be rendered.

We also support common Jupyter shortcuts and documentation popups. You can find the full list of available action shortcuts in the Help → Command palette menu tab.

Collaboration in Datalore

There are 4 ways to collaborate in Datalore.

1. Share your notebooks

Share your notebooks with your team via File → Share and collaborate in real time. The cursors of your team members will appear with color highlights and name tags. If something goes wrong you can revert to a history checkpoint via Tools → History.

2. Publish your notebooks

Publish your notebooks when you want to share insights and receive comments. Published notebooks can then be shared using a link.

3. Share whole workspaces

Share whole workspaces and work together with colleagues on multiple notebooks. Notebooks and attached files will be shared among all the workspace members. You can create a shared workspace via the Workspace menu on Datalore’s home screen.

4. Publish PyCharm notebooks

Publish PyCharm notebooks to share the results with your colleagues. You can upload them to Datalore from PyCharm IDE via the pre-installed Datalore plugin. Just make sure you are using version 0.1.18 or later.

Give Datalore a try!

Learn more about Datalore’s features from the Datalore blog. The Datalore team is always eager to hear your feedback! Please don’t hesitate to write to us in the comments or post in our forum.

Better user experience with updates in the R plugin

Over more than one and a half months, we introduced many improvements in the plugin to make your work with it more productive and comfortable.

New UI capabilities for managing R interpreters

You can easily switch between R interpreters, or create new ones with the R interpreter selector that is located in the IDE Status Bar.

Also, we modified the remote interpreter configuration: in addition to the host and interpreter path, you can specify the working directory on the remote server.

Better code assistance for R

With this release, R plugin provides additional support for code insight features:

• Static code completion for dplyr
• Code assistance for Shiny including HTML, Markdown, and CSS highlighting
• Support for S4 classes

Convenient import of data sets

We improved the workflow for importing data sets from CSV, TSV, or XLS files: reworked the UI and added a field to prompt an appropriate table name.

Improved testing of R packages

With the recenly added UI elements, you can easily create new tests for R source files in your packages and navigate from a source to a test.
Use the corresponding icon on the editor toolbar:

The same action can be found on the context menu of an R file in the Project tool window.

R Studio API support

With the support for R Studio API, you can now use its powerful features. For example, check R files with lintr:

You can also use the most popular functions: navigateToFile, askForPassword, and showQuestion. More features are to be supported in the next update releases of the plugin.

Interested?

Download PyCharm from our website and install the R plugin. See more details and installation instructions in PyCharm documentation.

PyCharm 2020.3 EAP #2

The second build of PyCharm 2020.3 is now available in the Early Access Program with features and fixes that will make your experience smoother and more productive.

We invite you to join the program to test, share your thoughts, and help us make a better PyCharm for you and all our users!

DOWNLOAD PYCHARM 2020.3 EAP

Highlights

Fast-track setup and reworked Welcome screen

Once PyCharm is installed, you’ll come to a new Welcome screen that includes, besides the project selection, also a variety of dialogs to help you customize your IDE even before starting it!

First of all, the "Projects" page has more space so you can see more projects and easily find the one you are looking for. If your list is too big to fit on the screen, you can always use the search bar that is, now, easier to spot on the top of the dialog modal.

The “Customize” tab lets you configure primary interface settings like the color theme, IDE font size, keymap, and more.

Finally, the “Plugins” tab enables you to browse the plugins marketplace and install any plugins you need (even before opening your project).

Splitting the editor with drag and drop tabs

This is a nice usability improvement! Have you ever needed to split your screen to edit more than one tab at the same time? This approach (very common when coding in TDD mode) used to require a couple of clicks from your side. Not anymore!

In PyCharm 2020.3, if you want to keep several tabs open and visible simultaneously on your screen, you can just drag and drop the tab into the desired position.

Rearranged VCS menu

The VCS menu will, now, match the version control system that you are currently using. Meaning that if you are, for instance, using Git, the VCS menu will look like the one below. The goal is to make the menu more specific and discoverable by making the most useful actions more prominent and no longer hidden in a submenu.

Notable fixes

• We fixed an old problem with ‘show method separators’ on nested functions.
• We fixed a problem that caused endless code analysis when coding with generics.
• We fixed a problem that popped-up the ‘out of memory’ dialog even when there was still memory available.

Early Access PyCharm Podcast — Episode 3: The One where Kirill talks about Version Control

Welcome to Early Access PyCharm, a brand-new podcast that goes behind the scenes of how the PyCharm IDE is made and all the thinking that goes into it. In the upcoming episodes, you will hear from the people who work daily to make you more productive and your code even better.

Episode 3

In this episode, we talk to Kirill, a proud member of the VCS (Version Control System) team, here at JetBrains. This is the team behind all your git support in your IDE. This is an interesting conversation, because the world of Version Control was not always so uniform.

A decade ago there were many competing applications, but most recently, git has come out victorious. Kirill talks about how the initial version control program in IntelliJ came to be, and how it supported both distributed and centralised systems.

Finding and fixing Python vulnerabilities in PyCharm with Snyk’s new plugin

This guest blog post is brought to you by Snyk.

Snyk offers a developer-first solution for open source security and presents now its new PyCharm plugin to help Python developers easily test their open source dependencies for security issues.

We’re happy to inform PyCharm users that a new Snyk plugin is now available, allowing Python developers to find and fix security vulnerabilities in their open source dependencies from within their favorite IDE!

“Shift left” is an important component of any DevSecOps motion but does not guarantee its success. The only way to ensure developers can successfully take on more responsibility for security is by providing them with developer-friendly tooling that integrates seamlessly into their existing workflows.

Being PyCharm the most popular IDE for Python development (with a 54% combined share for PyCharm Professional and Community editions, according to the JetBrains 2020 State of Developer Ecosystem survey), Snyk wanted to ensure Python developers had the ability to easily test their open source dependencies for security issues. The new plugin – the only SCA plugin for PyCharm – enables that.

The Snyk PyCharm plugin is free to use and available in the Jetbrains marketplace here.

Getting started

To use the plugin, first sign up with Snyk for free here. Also, make sure that the Python dependencies have been installed.

Installing the plugin itself is easy, exactly like any other plugin. From within PyCharm, go to Preferences → Plugins and search for “Snyk”. The Snyk plugin is displayed, and all you have to do is follow the instructions.

Hit the Install button – PyCharm downloads and installs the latest version of the Snyk CLI and a new Snyk tab appears at the bottom of PyCharm.

Before you start your first scan, be sure to authenticate your Snyk account. To do this, simply retrieve your API token from within Snyk and add it in the plugin’s settings, at: Preferences → Tools → Snyk:

Once successfully authenticated, open the Snyk tab and hit the Scan button to commence Snyk’s security testing. Within a few seconds, should the plugin identify any vulnerabilities, a list of issues will be displayed:

Scan results contain a wealth of information to help facilitate a quick fix, including the severity level for the vulnerability (based on CVSS) and the title/type of vulnerability. Additional details about the vulnerability expose how it was introduced by information on available exploits in the wild while an overview of the vulnerability explains how it can be exploited.

In terms of remediation, the Snyk plugin will help you fix the vulnerability by recommending the upgrade required. Snyk will always recommend the minimal path required to fix the specific issue to ensure minimal risk of breakage.

Clicking the details link at the bottom of the issue details takes you to Snyk’s vulnerability database, where you can gain more in-depth details on the vulnerability itself – severity scoring, version ranges, the way it can be exploited, and more.

Shifting left, the right way

When using open source, it’s important to check the risks being introduced. Testing the open source dependencies you pull into your Python projects for security issues is critical to ensure you are not sacrificing your organization’s security posture for fast development.

Shifting this testing left into your IDE enables you to surface issues early on in development and before even committing code into your repository. Instead of finding a critical vulnerability later on in the software delivery pipeline and having to re-engineer your code when it becomes more time consuming and technically difficult, testing your dependencies from the very moment you add them is simply more efficient and productive.

Adding to our existing IntelliJ and TeamCity plugins, this new PyCharm plugin is another step towards helping the JetBrains community of developers shift open source security left, the right way.
