Having colours in remote consoles
Hi all,
I was looking around in our deployment process and found out we deploy a file .iex.exs. Upon inspection this file only does Application.put_env(:elixir, :ansi_enabled, true). So I understand that this file is what enables colour when we use the remote_console. Now I don’t really like deploying this file just for that reason, so I started digging around how this works.
I found out that when starting a release, elixir decides to pass -elixir ansi_enabled true when stdin and stdout are both opened in a terminal. But because we start our release using systemd, the flag is not passed (at least I assume that’s the reason).
Although when running the remote_console I can see the flag is being passed to the that elixir process, but (I guess) because the release has ansi_enabled: false configured, there’s no colour.
So my question is in two-fold:
- Can the remote_console have colour based on it’s own ansi_enabled flag?
- Is it safe to just configure
ansi_enabled: truein the release config?

You can configure your own colours like this:
IEx.configure(
colors: [
syntax_colors: [
number: :light_yellow,
atom: :light_cyan,
string: :light_black,
boolean: :red,
nil: [:magenta, :bright],
],
ls_directory: :cyan,
ls_device: :yellow,
doc_code: :green,
doc_inline_code: :magenta,
doc_headings: [:cyan, :underline],
doc_title: [:cyan, :bright, :underline],
]
)
Just put that in .iex.exs
