set -e, -u, -o pipefail

The "set" lines These lines deliberately cause your script to fail. Wait, what? Believe me, this is a good thing. With these settings, certain common errors will cause the script to immediately fail, explicitly and loudly. Otherwise, you can get hidden bugs that are discovered only when they blow up in production.

set -euo pipefail is short for:

set -e
set -u

No need for sed or grep here. I solved the issue in a deploy script with

awk '/version/{gsub(/("|",)/,"",$2);print $2};' package.json

here's a stupid but fun way w/o awk or sed

grep version package.json | cut -c 15- | rev | cut -c 3- | rev

Cheers

Guide to your first Tree-sitter grammar

NOTE: The Tree-sitter API and documentation has changed and improved since this guide was created. I can't guarantee this is up to date.

About

Tree-sitter is the new way Atom is providing language recognition features, such as syntax highlighting, code folding, autocomplete, and more. In contrast to TextMate grammars, which work by regex matching, Tree-sitter will generate an entire syntax tree. But more on that can be found in it's own docs.

Here, we look at making one from scratch.
