If I make an improvement to rust-analyzer (and the maintainers approve it), then I've instantly improved every IDE or editor that relies of rust-analyzer. For example, Rust has rust-analyzer as their main LSP implementation - it's not maintained by any particular IDE or editor, but the developers of any IDE can create a plugin that uses it. With an LSP, you move a lot of the hard work out of the editor, which means even quite simple text editors have a lot more capability to do some quite powerful things. The idea behind the LSP was that you could build a small daemon server that could run on a developer's computer that would parse their code, find syntax errors, do refactorings, find places where a method was defined or used, etc. Traditionally, the big IDEs that had all the impressive features had to build these features directly into the IDE: each editor would have its own system for parsing code, checking types, applying refactorings, etc. It was reasonably lightweight, at least compared to traditional IDEs, but, it had some great code analysis for frontend languages (Javascript, Typescript, etc) builtin, and it had a promise of a powerful plugin system that could do anything a normal IDE could.Īround the same time (and not coincidentally), there was a growing push for the "LSP" or Language Server Protocol. Then at some point VSCode came along and set itself up as a sort of middle ground. Text editors tended to be much lighter and quicker, but IDEs tended to be way more powerful, albeit at the cost of requiring a more powerful machine. Generally, IDEs tend to be way more full-featured, with built-in debugging tools, hooks into your version control, much more powerful code analysis and autocompletion. Traditionally, there's been a big split between text editors (Notepad++, Sublime Text, Vim/Emacs, etc) and "real" IDEs (IntelliJ family, Eclipse, etc). It's all set up and ready to hit Run or Debug (ctrl r and ctrl d in my case). So if I have my env and start pycharm with its command line launcher from project directory, then the environment variables are available in Pycharm also. It's easier to manage environments (connection strings, API keys etc etc) in shell plus I can use my shell env directly, outside the IDE, too. Why? Because it enables starting the IDE with whatever environment I have in shell. No more messing with virtualenvs or anything - it handles it magically.Ģ use of Pycharm's command line launcher. Pycharm opens and perhaps asks me to confirm Poetry environment but rather not.ġ poetry is another fantastic tool that has changed the way I create, maintain and build Python libraries. Then, for a new project I do: $ poetry install
