Learn With Me: Elixir

In the previous section, I created a merging mechanism in the form of a merge stream that can produce a stream of merged integers from multiple integer files. That merge stream is really useful, but we haven't done anything with it yet. Today I'm

It's been a while since the last post. I had actually finished this project long ago and wrote the rought drafts of these posts as I was working on the project, but I haven't had time recently go over those and publish them. I've

In the last section, I created the building blocks for chunking integers and creating sorted chunk files. Today, I'll discuss how I composed them to actually do something. Naming the Intermediate Files I knew I was going to have to pass a callback function

We start with the IntSort project, creating the functions necessary to create chunk files

We update the IntGen project with a progress bar to show integer generation progress

I create a CLI interface for the IntGen program

I start working on the ElixirLargeSort project, creating the IntGen tool, which generates a file of random integers.

We learn about the functions in the File module and how to use them.

We learn about File I/O and the various methods of reading from and writing to files.

Elixir does not have loops, and that can be hard to get used to. So we learn what to do in Elixir when you need looping behavior.

We learn about Elixir protocols and how to use them.

We learn about behaviours and how they play a similar role to interfaces.

I talk about the editor and extensions I've been using for writing Elixir code

We learn about type specifications and how they help us understand Elixir code

We learn about functions in the Kernel module.

We learn about dependency injection and how it is used in Elixir

We learn about how to write and run doctests, which are unit tests embedded as examples in the documentation.

We learn about unit testing in Elixir and how to write your own tests.

We learn about Elixir documentation and how to create your own documentation for your code. Elixir makes this easy to do.

We learn about application packages and how to package the code in a project and run it.

We learn about some binary and math functions found in the Kernel module.

We learn about configuring an Elixir application

We learn about what Elixir considers to be an application vs what we typically think of as an application.

We learn about using dependencies in an Elixir project

We learn about managing dependencies in an Elixir project.
