Sublime Text is often the first editor that newer programmers pick up because Learn how these parts fit together in the development environments chapter or view all topics. Thanks to LSP maintainer Rafał Chłodnicki.Sublime Text is an implementation of the text editors and IDEs concept. Remove troubleshooting “index out of range” section which was fixed recently in LSP.Amend incorrect statement that LSP is officially supported by Sublime Text when it’s a community project.Added LSP-pylsp as main method of setup.Disable yapf formatter on LSP general settings as it seems to interfere with Black.Amend Black plugin to python-lsp-black.I would like to thank the Spyder IDE team for taking the time to fork and maintain Python LSP Server as well as to all the maintainers of the different plugins for PyLSP for adapting to the fork and releasing new versions promptly.Īnd, of course, the Sublime HQ team for making an awesome text editor. You may also want to install the following Sublime Text packages: If you find any issues with this setup let me know in this blog’s repo. Typical errors include missing dependencies and disabled or incorrect configurations, the logs will include which plugins are active and inactive. You should see the output of PyLSP in that log file which will help you debug any problems. The server should restart on each change to the project’s configuration file, but you may need to restart ST4 (luckily it’s lightning fast). If you find some of the plugins are not working or ST4 is showing an error about PyLSP crashing, you may want to add the following lines to the command list in the project’s config: If it is not set, or if it is incorrect you will not get errors in Sublime Text but simply no linting information. If you find things are working but you are not getting flake8 errors, make sure you’ve set up the setting in your project and it’s set to the correct absolute path. You should be able to see the effects described in the setup above.Make sure you replace with the absolute path to your virtual environment. Once installed go to the LSP-pylsp preferences and add the following configuration: LSP-pylsp is straight forward to setup as described in its README. Personally, I don’t use Pyright, so I will focus on LSP-pylsp and configuring it with a set of common plugins.

LSP-pyright, will only perform static typing, while LSP-pylsp has a plugin system that allows calling to other types of tools like linters and formatters like mypy, black, or isort. There are two main language servers available for ST4: LSP-pyright, which will perform type checking via Microsoft’s Pyright, and LSP-pylsp, which is based on Python LSP Server. Sublime Text does not officially support language servers, however, there is community support via the LSP project allowing plugins to call into different language servers and render results in ST4, and, of course, Python is no exception. Anaconda still works in ST4 but it’s unfortunately lacking some maintenance and its approach has been superseded by language servers. At the time the state-of-the-art way of working in Python was to use Anaconda (not to be confused with Anaconda, the Python distribution). I’ve used Sublime Text for Python since I bought my first ST3 license in 2017. When you choose ST4 you are sacrificing some IDE features for speed and performance. I will update this post with any developments in the tools and setup.ĭisclaimer: This setup will not make ST4 behave like P圜harm or even like VSCode. I’ve been using ST4 in its beta releases exclusively for some time and arrived at a setup that I enjoy, hopefully you will to. Sublime Text is not an IDE nor it pretends to be, but its powerful plugin system has allowed the community to come up with clever ways to have some IDE capabilities. Sublime Text has had its first major upgrade since 2017 with Sublime Text 4.
