ast-grep (via) There are a lot of interesting things about this year-old project.
sg (an alias for ast-grep) is a CLI tool for running AST-based searches against code, built in Rust on top of the Tree-sitter parsing library. You can run commands like this:
sg -p ’await await_me_maybe($ARG)’ datasette --lang python
To search the datasette directory for code that matches the search pattern, in a syntax-aware way.
It works across 19 different languages, and can handle search-and-replace too, so it can work as a powerful syntax-aware refactoring tool.
My favourite detail is how it’s packaged. You can install the CLI utility using Homebrew, Cargo, npm or pip/pipx—each of which will give you a CLI tool you can start running. On top of that it provides API bindings for Rust, JavaScript and Python! # 10th December 2023, 7:56 pm
Writing Python like it’s Rust (via) Fascinating article by Jakub Beránek describing in detail patterns for using type annotations in Python inspired by working in Rust. I learned new tricks about both languages from reading this. # 21st May 2023, 12:18 am
Rye. Armin Ronacher’s take on a Python packaging tool. There are a lot of interesting ideas in this one—it’s written in Rust, configured using pyproject.toml and has some very strong opinions, including completely hiding pip from view and insisting you use “rye add package” instead. Notably, it doesn’t use the system Python at all: instead, it downloads a pre-compiled standalone Python from Gregory Szorc’s python-build-standalone project—the same approach I used for the Datasette Desktop Electron app.
Armin warns that this is just an exploration, with no guarantees of future maintenance—and even has an issue open titled “Should Rye exist?” # 24th April 2023, 4:02 am
