Step one of crawling a web page is getting a fully fleshed out URL pointing to that page. The problem is that people usually think of URLs in fuzzy, incomplete terms. Thankfully, fleshing out the missing details is simple with Elixir.

I used to think that because length/1 was slow in guard clauses and could easily be replaced by pattern matching, that all guard clauses should be replaced by pattern matching. Turns out, some of those guard clauses are really quite quick!

Posted a new proposal to the mailing list, please take the time to read over it and let me know your thoughts! As new features can only be added if they’re supported on the mailing list, it’s vital that thoughts make it there :)

For those interested in deploying an Elixir/Phoenix app to Google Cloud, I’ve posted three getting-started tutorials on Google’s community site:

• Deploying to App Engine for spinning up an app with a minimum of work
• Deploying to Kubernetes Engine to get on board with containers
• Deploying to Compute Engine if you want complete control over your cloud resources

I love that mix hex.docs open ecto opens Ecto’s docs in my Browser. I’d love to have something like mix hex.readme open plug to open README.md files just as easy.

Given the current rage in team registrations (we have 28 already 😱), we decided to extend the registration deadline for @spawnfest one more day! #erlang, #elixir, #lfe devs… you have until tomorrow to register your team at https://spawnfest.github.io/registration and win some awesome prizes!

• Elimination of accidentally quadratic/maybe exponential, Data and Chart, negative-look-ahead in stab (do or fn body) parsing that led to slow parsing and slow reparse on hitting Enter.

Installation Instructions

Hey all, we recently released a major update to our error reporting client for Elixir at Honeybadger. Check it out!

Join us next weekend for a world-wide Beam-based hackathon at SpawnFest! You can win some amazing prizes provided by our sponsors :)

PlugCheckup provides a Plug for adding simple health checks to your app

https://github.com/whitfin/child-spec-compat

Provides compatibility macros for Supervisor.child_spec/2 inside libraries which support Elixir versions older than v1.5. Minimal, but it works!

All observer_cli Users are encouraged to upgrade to version 1.2.1.

• Add application status UI.
• Improve the rendering of UI(More efficient).
• Rearrange the UI and adjust the color(Easier to understand).
• Automatically adjust the row of the UI.
• Upgrade recon to 2.3.4.

Atom Elixir Formatter has received several improvements in the last month:

• Preserves document metadata (bookmarks, folds, etc) across formatting
• Supports conditional formatOnSave based on .formatter.exs file presence in project
• Dismisses outstanding notifications automatically on format success
• Full support for Windows

I have started a new tutorial series in which we will be covering the following topics:

• Create a new Phoenix project.
• Add a new Phoenix context for marketing leads.
• Add an API endpoint to insert a lead’s data into the database.
• Build the landing page template using Phoenix and Bulma as our CSS framework of choice.
• Add Elm to the project and build a subscription form that points to the API endpoint described previously.
• Add Google’s reCAPTCHA widget to the Elm subscription form, and how to render it and how to handle a visitor’s reCAPTCHA response.
• Build an HTTP client using HTTPoison to verify the token received by the reCAPTCHA widget against Google’s reCAPTCHA API from our backend.
• Build another HTTP client to subscribe leads to an email marketing service such as MailChimp.
• Add tests covering the subscription process using mocks for the HTTP clients.

I hope you enjoy it and happy coding!

This articles talks about a journey that started with an intention to better understand some of the concepts in Elixir via learning by doing and it takes one through the roadblocks I faced along the way and how I found ways of getting unstuck that lead me to reflect about things beyond Impostor Syndrome and how the overall learning experience helped me to be a better programmer in general.

• EEx support
  • Lexer for EEx format
  • Parser for EEx format
  • EEx as a Template Language
    • Any file with .eex as the final extension will be treated as EEx. To determine the Template Data Language, the .eex extension will be stripped and any remaining extension will be looked up to get the File Type and its associated Language. For example, *.txt.eex will be EEx with Plain Text (.txt) as the Data Template Language. Likewise, *.html.eex will be EEx with HTML as the Data Template Language. There’s no need to register *.txt.eex or *.html.eex or any other *.DATA_TEMPLATE_LANGUAGE_EXTENSION.eex pattern explicitly: the nested extension will be looked up using the normal extension setup.
• Decompile LocT chunk for private macros and functions and the derived names of anonymous functions.
• Parse HEAD-<SHA1> as 0.0.<SHA1> for sorting versions from homebrew homepath. It will almost always be last unless there is an unknown version, which uses 0.0.0.
• Ensure any unparsable version sorts as 0.0.0 (UKNOWN_VERSION).

Recently released benchee (the benchmarking library of your choice ;) ) in version 0.11 including a bugfix and optionally more statistics!

How do you deploy your application? Is Docker necessary, or even useful? What about service discovery, configuration and testing. Let’s take a simple chat application and make it scalable, fault-tolerant and available.

A brief introduction to Stream, talks about the similarity with lists and the kind of transformations that could be done on streams.

nerves_neopixel v0.3.2 has been released, primarily to add support for Raspberry Pi Zero and Zero W. Support for RGBW NeoPixels is not included but coming soon in a v0.4.0 release! https://hex.pm/packages/nerves_neopixel
