I am trying to use mix format
to format some graphql code but when I define the plugin it will work with a capital sigil IE ~G
but not a lowercase one ~g
. The problem is that some of the test code requires string interpolation which will not work with the uppercase sigil.
Is there a way to get a formatter plugin to work with a lowercase sigil? It has not worked when I have tried it?
You might open a feature request over on Absinthe to add sigil support to their formatter plugin, maybe?
I wrote a wrapper plugin, but it won’t format if you use the sigil ~g
it wants an uppercase letter.
I’d share the source code for your plugin if you want help!
sure, the module looks like this. What I want is to use the sigil ~g
vs ~G
so it does string escaping but that does not seem to work with mix format.
defmodule GraphqlFormatter do
@moduledoc """
Format graphql code when marked with the sigil ~G
"""
@behaviour Mix.Tasks.Format
def features(_opts) do
[sigils: [:G], extensions: []]
end
def format(contents, opts \\ []) do
Absinthe.Formatter.format(contents, opts)
end
end
I don’t think the expecation for external formatters is to be able to support elixir interpolation. With uppercase sigils and no interpolation you can be sure the to-be-formatted code is complete, uninterruped and only of syntax of the external format.
Have you tried adding :g
to the sigils list?
