Subnet: Making working with IP addresses in Crystal easy

In Ruby there are a slew of different options for working with IP addresses, including the built in IPAddr class, but up till now Crystal has been lacking such functionality.

But no more! Subnet is a shard that makes working with IP addresses in Crystal not only possible, but extremely simple. It allows addresses to be used in Range literals, the creation of subnets and supernets, and many other things.

You can check out the readme documentation here or check out the api documentation here. And don't forget to give it a star if you like it!

Sorry for bombarding you with projects ;)

Announcing Arachnid: A powerful web scraper for Crystal

I love Crystal and have been using it for years, but one of the things I've felt like was missing for a long time was a good web scraper. So, because I definitely don't have enough personal projects, I decided to start building one myself.

Arachnid is based heavily off of the Spidr Ruby gem, with the main difference currently just being Crystal (and Spidr probably works better at the moment). The whole goal of Arachnid is to provide an easy to use DSL for scraping the web, whether you're looking for html pages, javascript, zip files, images, or anything else.

You can see some examples in the README and more will be coming very soon, as well as full documentation.

Announcing Strange: A more powerful logger

I know what you're thinking, "why another logger?!" I'll tell you why. Nothing out there currently has the features that I'm looking for in a logger. It seems like every logger in the Crystal ecosystem is super opinionated and lacks support for custom formatting and transports, so I created Strange.

Strange is a logger for those who want to do more with logs than just print them to the console. It supports all of the levels outlined in RFC5424, custom transports that allow you to define exactly where your logs go (whether that be the console, a file, or an external service), and custom formatters that let you format the output exactly how you want.

Strange is inspired by Winston, a powerful logger for NodeJS.

Please check it out and make sure to visit the issue tracker if you have any questions, a feature request, or just want to tell me I suck 😝

The official Crystal snap is available

During the Snapcraft Summit Crystal team released the official snap package of the Crystal language

On Ubuntu 16.04 or later, you can install the Crystal snap with the following command:

sudo snap install crystal --classic

Snap uses the "channel" feature to release multiple Crystal series concurrently. For example, without specifying a channel, currently Crystal 0.29.0 will be installed. But if you want to install 0.30.0-dev, specify the latest/edge channel as follows:

sudo snap install crystal --edge --classic
