Nothing happens when I run mix format - is there something wrong with my .formatter.exs?

Questions / Help

I have the following .formatter.exs in a Phoenix project:

# Used by "mix format"

wildcard = fn glob -> Path.wildcard(glob, match_dot: true) end

matches = fn globs -> Enum.flat_map(globs, &wildcard.(&1)) end

# except = ["config/config.exs"]

except = []

inputs = ["*.{ex,exs}", "{config,lib,test}/**/*.{ex,exs}"]

[

  import_deps: [:phoenix, :phx_formatter],

  inputs: matches.(inputs) -- matches.(except),

  line_length: 80

]

My versions are:
Erlang/OTP 22 [erts-10.7] [64-bit] [smp:8:8] [ds:8:8:10] [async-threads:1]
Elixir 1.11.3 (compiled with Erlang/OTP 21)

I use Windows 10.

At times, when I run mix format, nothing happens.
Then I perform a fake update of .formatter.exs (adding a space and saving)
and then the next mix format works.
Is there something wrong with my .formatter.exs?

Why does it have to be “nudged” to “wake up”?

Thanks

It should work. I would try getting an existing project with the formatter, change a file, and see if it works. If it works, it is an issue with your formatter, otherwise the issue is elsewhere. :slight_smile:
