Steps to reproduce

1. Use SimpleTraits.jl and create a @traitfn function foo(bar::T) where {T; IsTrait{T}} end The Juno automatic formatting (Ctrl+J, Ctrl+F) give the error "no method matching rem_where(::Nothing)"

Works fine for me. What version of JuliaFormatter.jl do you have installed (you can check with pkg> st -m JuliaFormatter)?

Edit: Oh, actually, it doesn't error but still messes up: @traitfn function foo(bar::T) where {T; IsTrait{T}} end -> @traitfn function foo(bar::T) where {TIsTrait{T}} end

JuliaFormatter is at version 0.3.8

Are you sure it's that line that causes the error (you can check by only selecting that before formatting)?

[theogf]

Here is what it gives when I select a line with @traitfn :

Parsing error for input:
@traitfn function predict_ar(m::TGP, p::Int = 3, n::Int = 1; y_past = get_y(m)) where {T,TGP<:AbstractGP{T};IsMultiOutput{TGP}}

The rem_where issue was when I was selecting the whole function

[pfitzseb]

Ah ok, I can repro with that function. Wanna open an issue about this at the JuliaFormatter repo?

[theogf]

Sure! Probably it's the combination of comas and semicolumn...
