#210 on MacOS

Installing Elixir on MacOS

Notes

Trying two options for running Elixir on MacOS - brew and docker

Using Homebrew

Installing with brew and the Elixir Homebrew Fomula

$ brew update
$ brew install elixir
$ brew info elixir
elixir: stable 1.10.0 (bottled), HEAD
Functional metaprogramming aware language built on Erlang VM

install-on-request: 7,290 (30 days), 22,832 (90 days), 94,499 (365 days)
build-error: 0 (30 days)

Installed version:

$ elixir --version
Erlang/OTP 22 [erts-10.6.2] [source] [64-bit] [smp:8:8] [ds:8:8:10] [async-threads:1] [hipe] [dtrace]

Elixir 1.10.0 (compiled with Erlang/OTP 22)

Running the REPL:

$ iex
Erlang/OTP 22 [erts-10.6.2] [source] [64-bit] [smp:8:8] [ds:8:8:10] [async-threads:1] [hipe] [dtrace]

Interactive Elixir (1.10.0) - press Ctrl+C to exit (type h() ENTER for help)
iex(1)> System.version
"1.10.0"
iex(2)> :c.uptime
34 seconds
:ok
iex(3)>

Running scripts:

$ elixir demo.exs
System.version: 1.10.0

Using Docker

Official Elixir Docker images are published on Docker Hub

Running interactive:

$ docker run -it --rm elixir
Unable to find image 'elixir:latest' locally

Status: Downloaded newer image for elixir:latest
Erlang/OTP 22 [erts-10.6.2] [source] [64-bit] [smp:4:4] [ds:4:4:10] [async-threads:1] [hipe]

iex(1)> System.version

:ok
iex(3)>

Run a single Elixir exs script: this command maps the current directoty to /usr/src/myapp in the container and sets this as the working directory to run the names script:

$ docker run -it --rm --name elixir-lckdemo -v "$PWD":/usr/src/myapp -w /usr/src/myapp elixir elixir demo.exs
System.version: 1.10.0

LittleCodingKata is my collection of programming exercises, research and code toys broadly spanning things that relate to programming and software development (languages, frameworks and tools).

These range from the trivial to the complex and serious. Many are inspired by existing work and I'll note credits and references where applicable. The focus is quite scattered, as I variously work on things new and important in the moment, or go back to revisit things from the past.

This is primarily a personal collection for my own edification and learning, but anyone who stumbles by is welcome to borrow, steal or reference the work here. And if you spot errors or issues I'd really appreciate some feedback - create an issue, send me an email or even send a pull-request.
