Hey! Thank you for creating an issue. Do you have an idea of how an executable script could be run with either nodejs or bun? I can think of a statically built executable (probably with bun) but I have concerns. It would be great to know if there's a common solution for such cases. I will investigate

[cethien]

bun is intended as a node replacement, so just calling a script.js file should work fine.

It would be great to know if there's a common solution for such cases. I will investigate

i will check out some stuff and give a comment

@mrexox @cethien #705 maybe fixes this case as removes require of Node.js and #!/usr/bin/env node

For those of you, that want to utilize this package with bun now, Ive figured out a quick patch solution until bun support has been officially added.

Add these to your package.json file and you'll be good to go.

"prepare:lefthook": "lefthook install && bun -e \"const fs=require('node:fs'); fs.writeFileSync('node_modules/lefthook/bin/index.js', fs.readFileSync('node_modules/lefthook/bin/index.js', 'utf8').replace(/^#!\\/usr\\/bin\\/env\\s+node/gm, '#!/usr/bin/env bun'))\"",
"postinstall": "bun prepare:lefthook"
