WIP: Rust implementation of packs and packwerk for ruby
packs!packs can do is generate a cache to be used by the ruby implementation.One simple way to try out packs to generate your cache would be to create a bash function which wraps the call to bin/packwerk, like so:
```bash
packwerk() { if [ "$1" = "check" ] || [ "$1" = "update" ]; then echo "Calling packs generatecache with args: ${@:2}" packs generatecache "${@:2}" fi
echo "Now calling packwerk with args: $@"
bin/packwerk "$@"
} ```
You can also modify the bin/packwerk executable to call packs conditionally, e.g.
```ruby
packsexecutable = which packs.chomp
if !packsexecutable.empty?
if ARGV.first == 'check' || ARGV.first == 'update'
puts "Calling packs generatecache with args: #{ARGV[1..-1]}"
system('packs', 'generatecache', *ARGV[1..-1])
end
end
```
As packs is still a work-in-progress, it's possible it will not produce the same results as the ruby implementation (see below). If not, please file an issue!
To verify:
1. Run rm -rf tmp/cache/packwerk to delete the existing cache.
2. Run packs generate_cache (see directions below to get binary)
3. Run bin/packwerk update to see how violations change using packs.
Deployment ergonomics are still a WIP.
If you want to try it out:
- Go to https://github.com/alexevanczuk/packs/releases
- Download the packs asset and run chmod +x path/to/packs
- Open the containing directory, right click on the binary, click open, and then accept the warning message that says its from an unknown developer (it's me!)
- Execute path/to/packs to see the CLI help message.
You can add path/to/packs to your PATH so it's available in every terminal session.
In the future, I hope to: - Somehow sign the binary so it does not get a warning message - Make it executable before download - Add directions to download via some other tool, or ship as a native ruby gem extension.
Me too! This is my first Rust project, so I'd love to have feedback, advice, and contributions! If you're new to Rust, don't be intimidated! https://www.rust-lang.org has tons of great learning resources.
