Subject: [PATCH] gnu: Add tree-sitter.

From: Luis Henrique Gomes Higino <[email-masked]>
Date: Tue, 25 Jan 2022 11:33:51 -0300

Hi guixers,

this series of patches adds the new required dependency for neovim,
tree-sitter, updates neovim to the newest upstream version and adds
the package variant neovim-luajit, which switches the lua
implementation used from Lua 5.1 to LuaJIT 2.1.0-beta3.

* gnu/packages/text-editors.scm (tree-sitter): New variable.

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