Package Chrome extensions with Ruby. Inspired by (Loosely based on? Stolen from?) crxmake. Use the CLI or the Ruby API.

Install

gem install extensionator

What you need

You need a private key so sign the extension with, and this is a BYOK (bring your own key) library. So first, you need a PEM file. If you have one, cool. If not, do this:

openssl genrsa -out key.pem 2048

You'll also need a directory to package up. Extensionator doesn't pay any attention to the contents; it just repackages them. So if you're misssing a manifest.json or your files are encoded wrong or whatever, you won't find out until you try to load the packed extension into Chrome.

Command line

extensionator -d directory/with/extension -i key.pem -o output.crx

You can also exclude files with a regex, which will be applied to each level of the path (so if you have foo/bar/baz.stuff, we compare the regex to "foo", "foo/bar", and "foo/bar/baz.stuff"):

extensionator -d directory/with/extension -i key.pem -o output.crx -e "\.md$"

If you're one of those people, here's this thing:

-> extensionator -h
usage: /Users/isaac/.gem/ruby/2.1.5/bin/extensionator [options]
    -d, --directory  Directory containing the extension. (Default: .)
    -i, --identity   Location of the pem file to sign with. (Required)
    -o, --output     Location of the output file. (Default: 'extension.crx')
    -e, --exclude    Regular expression for filenames to exclude. (Default: \.crx$)
    -v, --version    Extensionator version info.
    -h, --help       Print this message.

Programmatically

Same as above, but:

require "extensionator"
Extensionator.create("directory/with/extension", "key.pem", "output_file.crx")

Or with an exclude option:

Extensionator.create("dir", "key.pem", "output_file.crx", exclude: /\.md$/)
