Nimpretty --maxLineLine seems broken

[Clonk]

The problem is that I'm using Nimpretty in a Vim config file as a parameters 
for the ALE Plugin (<https://github.com/dense-analysis/ale>) : 
    
    
    let g:ale_fixers = { \
     '*': ['remove_trailing_lines', 'trim_whitespace'], \
      'nim': ['nimpretty'], \
    }
    
    
    Run

And it automatically cut the line at 80. I could remove the formatting, I'm 
pretty satisfied I just wish I could increase the line length as 80 character 
is quite short in my opinion (I have a wide screen).
