Working effectively with legacy Erlang code

TALK LEVEL: INTERMEDIATE / PROFICIENT

Loosely based on the book by Michael Feathers with the same title, this talk summarises Brujo's personal experience developing and maintaining Erlang systems with many years of age.

Brujo will share some techniques and tools that you can use if you ever find yourself in the position of maintaining (and maybe expanding) a legacy code base for a huge system written in Erlang.

THIS TALK IN THREE WORDS

Legacy

Erlang

Maintainability

OBJECTIVES

The goal is to provide tools and techniques to reduce the stress, the fear, and the hopelessness that tend to be common among those who face legacy systems for the first time.

TARGET AUDIENCE

  • People that just started or are considering working in huge, old systems.
  • People who wants to build systems that will be maintainable for many years to come.

OTP behaviours and how to behave around them

One of the first things every newcomer faces when they meet OTP are behaviours. The general explanation for them is usually along the lines of "they're like interfaces for OOP". While that's somewhat accurate, it's also misleading and introduces a lot of confusion on how and when to use the existing behaviours and when it's reasonable to define your own ones. In this talk, Brujo will explain what behaviours are, how they should be used and how to create and expose new ones if you ever need to.

OBJECTIVES

To help newcomers get familiar with OTP behaviours and to help experienced devs rediscover them.

TARGET AUDIENCE

Developers willing to understand what they really do when they implement a generic server or a supervisor. Also folks considering the creation of their own behaviours with the desire to do it right. If you don't know what a behaviour is at all, you're welcome here too.

rebar3 format: A new code formatter for Erlang

In recent years, many language ecosystems have developed automatic code formatters to reduce the mental overhead of code readers and therefore to share code more easily. The Erlang community was lacking a tool like this, so we created a rebar3 plugin just to automatically format code.

OBJECTIVES

To show the new currently available and open-source rebar3 plugin to automatically format Erlang code that we created.

Opaque Structures and Other Yerbas

Opaque Data Structures provide a very nice technique to structure systems and they are particularly useful within the functional programming paradigm. With the addition of maps and the opaque attribute for modules, Erlang is now perfectly suited to get the best of these structures, if you use it properly.

In this talk, Brujo will show what opaque data structures are, how to use them and why they are so useful, even more so if you're developing an open-source library. This talk will be conceptual, but it won't be 100% theoretical.

Brujo will also present examples and tools that assist us in making better use of these techiques.

OBJECTIVES

The main goal of the talk is to showcase a way to structure Erlang systems based on strong type definitions and explain why and how that structure is beneficial to Erlang developers.

AUDIENCE

Everyone, but it might be of particular interest for those building open-source libraries and/or big applications with lots of modules.
