2020-12-14 13:10:00 An incremental parsing system for programming tools written in #rust

Tree-sitter is a parser generator tool and an incremental parsing library. It can build a concrete syntax tree for a source file and efficiently update the syntax tree as the source file is edited.

Tree-sitter aims to be:
- General enough to parse any programming language
- Fast enough to parse on every keystroke in a text editor
- Robust enough to provide useful results even in the presence of syntax errors
- Dependency-free so that the runtime library (which is written in pure C) can be embedded in any application

Beartype brings Rust inspired zero-cost abstractions into the lawless world of dynamically-typed pure Python.

Beartype is portably implemented in Python 3, continuously stress-tested via GitHub Actions + tox + pytest, and permissively distributed under the MIT license. Beartype has no runtime dependencies, only one test-time dependency, and supports all Python 3.x releases still in active development.

Feature highlights:
- Construct templates using a familiar, easy-to-use syntax
- Template code is compiled into your crate for optimal performance
- Benefit from the safety provided by Rust's type system
- Optional built-in support for Actix, Gotham, Iron, Rocket, tide, and warp web frameworks

> While I do like flower, to me it's not been totally up to the task (pun intended :).
Why is that? flower needs page refreshes, filters only one task type at a time, displays results as plain strings without any formatting or syntax highlighting, and on top of that also truncates them!

> And clearly is actually real time, has multiple simultaneous filters, a beautiful syntax highlighting system, an advanced formating system that shows parameters, results and tracebacks just as an ipython would, has complete un-truncated results and is very easy to use! Also you can install it very easily with a docker image!

> It's great to actually see in a totally real time way what's going on in your celery workers! So it's very nice for inspecting, debugging, and even demonstrating your company async-superpowers (put clearly on a big screen TV showing all tasks of your production environment)!

> Clearly is composed of a server, which collects real time events from the celery cluster, generates missing states, and streams filtered data to connected clients; and a client, which you use to send filter commands and display both real time and stored data. They communicate with each other via gRPC and ProtocolBuffers.
