I have updated ex_lcd to better handle external dependencies. No new functionality is included in this release.

Just released v0.4 for phone, a parser to extract information from telephone numbers without consulting any external source. This release improves performance a lot, going from 1ms in worst cases to 10µs. This performance gain is due to some complexity in the lib, so expect a long compilation time. In this release was added too a valid?/1 function, to verify if its a valid telephone number without parsing. hex github

In my latest blog post I compare three well-known benchmarking libraries available for Elixir, focusing on their pros and cons with some sample codes to help in understanding. https://blog.digitalnatives.hu/benchmarking-elixir-benchmarking-tools/

Tired of the duplication in writing code like %{id: id, first_name: first_name, last_name: last_name}? Dry it up with ~M{id, first_name, last_name}.

Here are the syntactic variants the macro exposes:

• Atom keys: ~M{a, b} => %{a: a, b: b}
• String keys: ~m{a, b} => %{“a” => a, “b” => b}
• Structs: ~M{%Person id, name} => %Person{id: id, name: name}
• Pinned variables: ~M{^a, b} => %{a: ^a, b: b}
• Ignore matching: ~M{_a, b} => %{a: _a, b: b}
• Map update: ~M{old|a, b, c} => %{old|a: a, b: b, c: c}
• Mixed mode: ~M{a, b: b_alt} => %{a: a, b: b_alt}

~M and ~m (atom vs. string keys) can be used to replace maps anywhere in your code: creating maps from existing variables, creating new variables while destructuring maps, pattern matching in lambdas, function heads or case statements.

See it on Github. Get it with {:shorter_maps, “~> 2.0”},

https://hex.pm/packages/cookie_jar

This lib helps with hacking around (building clients/bots to access) websites that rely on cookies to store user status, e.g. auth, page history, etc. It has httpoison and httpotion integration builtin.

Check the docs and source code.

Normally in MVC frameworks, the view and the template are essentially the same thing. But in the case of Phoenix Framework, they refer to different components…Phoenix templates are compiled to rendering functions and are placed in the corresponding view modules…

I updated the ex_lcd hex package to 0.3.2 to resolve a dependency issue. ExLCD is a library to easily use character matrix LCD displays in your Elixir nerves projects.

Can we have Form Objects in Elixir? It’s a functional language, isn’t it? But thanks to many features it gives us, we can leverage them to mimic Form Object pattern in our applications! Check this out: https://blog.lelonek.me/form-objects-in-elixir-6a57cf7c3d30
