base on Heroku's classic buildpack for Ruby applications. # Heroku Buildpack for Ruby  This is a [Heroku Buildpack](http://devcenter.heroku.com/articles/buildpacks) for Ruby, Rack, and Rails apps. It uses [Bundler](https://bundler.io) for dependency management. This buildpack requires 64-bit Linux. ## Usage ### Ruby Example Usage: $ ls Gemfile Gemfile.lock $ heroku create --buildpack heroku/ruby $ git push heroku main ... -----> Heroku receiving push -----> Fetching custom buildpack -----> Ruby app detected -----> Installing dependencies using Bundler version 1.1.rc Running: bundle install --without development:test --path vendor/bundle --deployment Fetching gem metadata from http://rubygems.org/.. Installing rack (1.3.5) Using bundler (1.1.rc) Your bundle is complete! It was installed into ./vendor/bundle Cleaning up the bundler cache. -----> Discovering process types Procfile declares types -> (none) Default types for Ruby -> console, rake The buildpack will detect your app as Ruby if it has a `Gemfile` and `Gemfile.lock` files in the root directory. It will then proceed to run `bundle install` after setting up the appropriate environment for [ruby](http://ruby-lang.org) and [Bundler](https://bundler.io). ## Documentation For more information about using Ruby and buildpacks on Heroku, see these Dev Center articles: - [Heroku Ruby Support](https://devcenter.heroku.com/articles/ruby-support) - [Getting Started with Ruby on Heroku](https://devcenter.heroku.com/articles/getting-started-with-ruby) - [Getting Started with Rails 7 on Heroku](https://devcenter.heroku.com/articles/getting-started-with-rails7) - [Buildpacks](https://devcenter.heroku.com/articles/buildpacks) - [Buildpack API](https://devcenter.heroku.com/articles/buildpack-api) ## Hacking To use this buildpack, fork it on Github. Push up changes to your fork, then create a test app with `--buildpack <your-github-url>` and push to it. ### Testing ```sh $ bundle exec hatchet install ``` ```sh $ bundle exec rake spec ``` ", Assign "at most 3 tags" to the expected json: {"id":"14823","tags":[]} "only from the tags list I provide: [{"id":77,"name":"3d"},{"id":89,"name":"agent"},{"id":17,"name":"ai"},{"id":54,"name":"algorithm"},{"id":24,"name":"api"},{"id":44,"name":"authentication"},{"id":3,"name":"aws"},{"id":27,"name":"backend"},{"id":60,"name":"benchmark"},{"id":72,"name":"best-practices"},{"id":39,"name":"bitcoin"},{"id":37,"name":"blockchain"},{"id":1,"name":"blog"},{"id":45,"name":"bundler"},{"id":58,"name":"cache"},{"id":21,"name":"chat"},{"id":49,"name":"cicd"},{"id":4,"name":"cli"},{"id":64,"name":"cloud-native"},{"id":48,"name":"cms"},{"id":61,"name":"compiler"},{"id":68,"name":"containerization"},{"id":92,"name":"crm"},{"id":34,"name":"data"},{"id":47,"name":"database"},{"id":8,"name":"declarative-gui "},{"id":9,"name":"deploy-tool"},{"id":53,"name":"desktop-app"},{"id":6,"name":"dev-exp-lib"},{"id":59,"name":"dev-tool"},{"id":13,"name":"ecommerce"},{"id":26,"name":"editor"},{"id":66,"name":"emulator"},{"id":62,"name":"filesystem"},{"id":80,"name":"finance"},{"id":15,"name":"firmware"},{"id":73,"name":"for-fun"},{"id":2,"name":"framework"},{"id":11,"name":"frontend"},{"id":22,"name":"game"},{"id":81,"name":"game-engine "},{"id":23,"name":"graphql"},{"id":84,"name":"gui"},{"id":91,"name":"http"},{"id":5,"name":"http-client"},{"id":51,"name":"iac"},{"id":30,"name":"ide"},{"id":78,"name":"iot"},{"id":40,"name":"json"},{"id":83,"name":"julian"},{"id":38,"name":"k8s"},{"id":31,"name":"language"},{"id":10,"name":"learning-resource"},{"id":33,"name":"lib"},{"id":41,"name":"linter"},{"id":28,"name":"lms"},{"id":16,"name":"logging"},{"id":76,"name":"low-code"},{"id":90,"name":"message-queue"},{"id":42,"name":"mobile-app"},{"id":18,"name":"monitoring"},{"id":36,"name":"networking"},{"id":7,"name":"node-version"},{"id":55,"name":"nosql"},{"id":57,"name":"observability"},{"id":46,"name":"orm"},{"id":52,"name":"os"},{"id":14,"name":"parser"},{"id":74,"name":"react"},{"id":82,"name":"real-time"},{"id":56,"name":"robot"},{"id":65,"name":"runtime"},{"id":32,"name":"sdk"},{"id":71,"name":"search"},{"id":63,"name":"secrets"},{"id":25,"name":"security"},{"id":85,"name":"server"},{"id":86,"name":"serverless"},{"id":70,"name":"storage"},{"id":75,"name":"system-design"},{"id":79,"name":"terminal"},{"id":29,"name":"testing"},{"id":12,"name":"ui"},{"id":50,"name":"ux"},{"id":88,"name":"video"},{"id":20,"name":"web-app"},{"id":35,"name":"web-server"},{"id":43,"name":"webassembly"},{"id":69,"name":"workflow"},{"id":87,"name":"yaml"}]" returns me the "expected json"
