Enable syntax highlighting for inline Phoenix LiveView templates by using the polymode library.

Get the code. It should work with all popular frameworks or vanilla configurations.

Started a learn-in-public project to finally learn and love Elixir and Phoenix. This blog post is the first in a series where I document my progress and failures.

Learn Elixir and Phoenix by building a read-it-later service: Project Setup

In this episode of ElixirMix, Mark talks with Fernando Hamasaki de Amorim about his experience adopting Elixir at FindHotel.net. He shares his strategy of introducing Elixir through hack-a-thons, what kinds of projects work well to start with and tips around learning and building a team. We discuss umbrella projects, pattern matching for data transformation, learning about managing configuration in Elixir applications and much more!

Correios CEP allows to find Brazilian addresses by zip code, directly from Correios API. No HTML parsers.

Now you can find address using a proxy.

# Not using a proxy
iex> Correios.CEP.find_address("54250610")
{:ok,
 %Correios.CEP.Address{
   city: "Jaboatão dos Guararapes",
   complement: "",
   neighborhood: "Cavaleiro",
   state: "PE",
   street: "Rua Fernando Amorim",
   zipcode: "54250610"
 }}

# Using a proxy
iex> Correios.CEP.find_address("54250610", proxy: {"myproxyhost", 8888})
{:ok,
 %Correios.CEP.Address{
   city: "Jaboatão dos Guararapes",
   complement: "",
   neighborhood: "Cavaleiro",
   state: "PE",
   street: "Rua Fernando Amorim",
   zipcode: "54250610"
 }}

# Using a proxy with authentication
iex> Correios.CEP.find_address("54250610", proxy: {"myproxyhost", 8888}, proxy_auth: {"myuser", "mypass"})
{:ok,
 %Correios.CEP.Address{
   city: "Jaboatão dos Guararapes",
   complement: "",
   neighborhood: "Cavaleiro",
   state: "PE",
   street: "Rua Fernando Amorim",
   zipcode: "54250610"

This has been a pretty long-running hobby project of mine: A real world traffic light that shows the status of our CI server. I think I maintained and overengineered this for almost a decade and implemented it with various hardware and programming languages.

The newest iteration is done in Elixir, with the help of Nerves and Phoenix.
