It’s has been a long time since i’m doing a blog, also writing some experiment results or technical tutorial. Now, i’m back. Currently, i’m starting to know more about functional programming and Elixir (because of work). So, i decided to also write this blog using Elixir. More precisely using Serum. Serum is a simple static generator written in Elixir. I don’t need the functionality of Phoenix for just a simple blog. I’ll show you the way on how to deploy Serum

asdf : the multiple runtime version manager

Do you run multiple runtime system for your work ? You maybe run several version of Ruby, multiple version of Python, and also Rust on your machine. Fear not, there is now a single runtime manager for all those languages. Its written on shell script and can be extended with multiple plugins to support your preferred language and runtime environment. It’s called asdf

So, before i start using Elixir and Serum, i installed this manager on the machine with i’m working with as the server for this blog. Here are the steps you need to deploy asdf into your box.

• install the dependencies

  • sudo apt install curl git

• clone asdf latest branch

  • git clone https://github.com/asdf-vm/asdf.git ~/.asdf --branch v0.7.8

• add asdf to our shell

  • add the following to your ./bashrc

    • . $HOME/.asdf/asdf.sh
    • . $HOME/.asdf/completions/asdf.bash

• restart your shell or just sourced your ./bashrc

  • source ~/.bashrc

deploying elixir using asdf

elixir and BEAM vm also can be managed using asdf.

• install asdf erlang/otp plugin and elixir plugin

  • asdf plugin add erlang
  • asdf plugin add elixir

• install BEAM vm and erlang/otp runtime using asdf

  • asdf install erlang 22.3.3 + install elixir using asdf -asdf install elixir 1.10.3-otp-22

creating your serum site

serum is really easy to install, because its already wrapped into Hex package

• install serum as mix archive

  • mix archive.install hex serum_new

• initiate your site

  • mix serum.new $HOME/segmentationfault_xyz

• fetch the dependencies

  • cd $HOME/segmentationfault_xyz
  • mix deps.get && mix compile

• start to write content

  • post in form of pages are located under /pages directory
  • blog posts are located under /posts directory. write a post in a form of markdown document formatted add a theme into your site

• add a theme as dependency on your mix.exs file

    defp deps do
    [
        {:serum, "~> 1.4"},
        {:serum_theme_essence, "~> 1.0"}
    ]
    end

• in order to check your post, you can run a serum server on your box

  • $ mix serum.server --port 8080

• build your site

  • MIX_ENV=prod mix serum.build
• all site structure and assets will be put under /site directory. you can serve this directory using web server such as nginx
• done. enjoy!

Note : this site structure is put under this github repository.
