Configure formatter to ignore some part of code

Hello everyone, I have a noob question about formatter…

I have this code

  @attack_array [
    0,0,0,0,0,0,0,0,0,5,0,0,0,0,0,0,2,0,0,0, # 0-19
    0,0,0,5,0,0,5,0,0,0,0,0,2,0,0,0,0,0,5,0, # 20-39
    0,0,0,5,0,0,0,0,2,0,0,0,0,5,0,0,0,0,0,0, # 40-59
    5,0,0,0,2,0,0,0,5,0,0,0,0,0,0,0,0,5,0,0, # 60-79
    2,0,0,5,0,0,0,0,0,0,0,0,0,0,5,6,2,6,5,0, # 80-99
    0,0,0,0,0,0,0,0,0,0,6,4,1,4,6,0,0,0,0,0, # 100-119
    0,2,2,2,2,2,2,1,0,1,2,2,2,2,2,2,0,0,0,0, # 120-139
    0,0,6,3,1,3,6,0,0,0,0,0,0,0,0,0,0,0,5,6, # 140-159
    2,6,5,0,0,0,0,0,0,0,0,0,0,5,0,0,2,0,0,5, # 160-179
    0,0,0,0,0,0,0,0,5,0,0,0,2,0,0,0,5,0,0,0, # 180-199
    0,0,0,5,0,0,0,0,2,0,0,0,0,5,0,0,0,0,5,0, # 200-219
    0,0,0,0,2,0,0,0,0,0,5,0,0,5,0,0,0,0,0,0, # 220-239
    2,0,0,0,0,0,0,5,0,0,0,0,0,0,0,0,0        # 240-256
  ]
  @delta_array [

    -17,   0,   0,   0, -16,   0,   0,   0, -15,   0,   0,   0,   0,   0,   0,   0,   0, -17,   0,   0,
    -16,   0,   0, -15,   0,   0,   0,   0,   0,   0,   0,   0,   0,   0, -17, -33, -16, -31, -15,   0,
    0,   0,   0,   0,   0,   0,   0,   0,   0,   0, -18, -17, -16, -15, -14,   0,   0,   0,   0,   0,
    0,  -1,  -1,  -1,  -1,  -1,  -1,  -1,   0,   1,   1,   1,   1,   1,   1,   1,   0,   0,   0,   0,
    0,   0,  14,  15,  16,  17,  18,   0,   0,   0,   0,   0,   0,   0,   0,   0,   0,   0,  15,  31,
    16,  33,  17,   0,   0,   0,   0,   0,   0,   0,   0,   0,   0,  15,   0,   0,  16,   0,   0,  17,
    0,   0,   0,   0,   0,   0,   0,   0,  15,   0,   0,   0,  16,   0,   0,   0,  17,   0,   0,   0,
    0,   0,   0,  15,   0,   0,   0,   0,  16,   0,   0,   0,   0,  17,   0,   0,   0,   0,  15,   0,
    0,   0,   0,   0,  16,   0,   0,   0,   0,   0,  17,   0,   0,  15,   0,   0,   0,   0,   0,   0,
    16,   0,   0,   0,   0,   0,   0,  17,   0,   0,   0,   0,   0,   0,   0,   0,   0
  ]

I would like obviously to keep this structure, but when I run formatter, it will output each number on a single line. I have been looking at mix format — Mix v1.20.2 but could not find a way to preserve format. Is there a way to tell formatter to ignore constants?

Thanks for taking time.

Only way I could think of is to enter the list as a string using heredoc and eval it with Code.eval_string. But I haven’t tried it. I hope that helps.

Thank You for the response, I would prefer to set exclusion rules in formatter, but could not find it yet how to do so. If I cannot, I might use your solution

There aren’t any exclusion rules in the formatter. The closest you could achieve is not formatting the file at all. In the .formatter.exs, you can specify an inputs pattern to match files to format. Make the pattern not match that file to have it not formatted.

@aptinio’s suggestion isn’t a bad one. When I have data like this, I typically prefer to put it in a file that is conducive to the format. For me, that’s typically JSON and CSV. You can make the elixir compiler aware that you depend on a file at compile time by using @external_resource [1].

Thanks for the response, I will put this code apart… and exclude the file. That will solve my problem.

Using @aptinio suggestion I now have this after format…

  @attack_array Code.eval_string("""

This is good enough for me, thank You both for your advices
