This article was discussed on Hacker News. This is a continuation of my last post on how to write a tree-sitter grammar in an afternoon. Building on the grammar we wrote, now we’re going to write a linter for Imp, and it’s even easier! The final result clocks in less than 60 SLOC and can be found here. Recall that tree-sitter is an incremental parser generator. That is, you give it a description o
About two months ago, @maxdeviant and I began the project of making Zed extensible. In a code editor, extensibility can include many features that require many different capabilities, but for the first phase of the project, we have focused on extensible language support. We want people to be able to code in Zed in any programming language, not just a select few. We've just reached that first miles

Tree Sitter and the Complications of Parsing Languages I talk about tree sitter, CEDET, and Combobulate – my "paredit-style" package that's designed to work with most programming languages. You might be surprised to hear when you visit a file in Emacs that the syntax highlighting you are shown on your screen is – most likely – a potpourri of regular expressions with a dash of functions and syntax

Combobulate: Structured Movement and Editing with Tree-Sitter
Combobulate: Structured Movement and Editing with Tree-Sitter Combobulate is a package that adds advanced structured editing and movement to many programming modes in Emacs. Here's how it works, and how it can enrich your editing experience in Emacs. About a year ago I released an alpha – prototype, really – version of a tool I call Combobulate. I’d been using it personally for a while before I le
