Adding headers to an already existing file

[aminya]

I use the Parcel bundler to generate my built script. It would be nice if we could prepend the header to this generated file (by specifying the path).

Agreed, that's already planned - for now, we've been using the following simple shell script to prepend the headers:

#!/bin/bash

dist="dist"
output=$dist"/headers.js"

generate-headers tampermonkey \
    -o $output \
    -m all meta \
    -g get set delete unsafe \
    --collapse \
    --pretty

# given the output is "dist/something.js" and the metadata file is "dist/headers.js"
userscript="$(find -iwholename "./$dist/*\.js" -type f -not -iname "*headers\.js")"

sed -i -e "{1e cat $output; echo; echo" -e "; N}" $userscript
