Parsing error

Octogonapus opened this issue · comments

I've run into this parsing error during formatting that occurs when my format action runs in CI. When I run the same version of JuliaFormatter on what I think is the same code locally, I don't get an error.

Line 84, offset 4 is the end of the triple quote in this snippet if it helps:

Foo(2, 3)
\`\`\` # backslashes since GitHub formatting is being difficult here
"""
function foo

Do you have any advice on how I can debug this further?

Julia v1.9.0
JuliaFormatter v1.0.33

Correct. I've replicated my CI setup locally, and the error happens only in CI.

I've managed to reproduce it locally. Here are some cases where the error happens:

    module foo
    """
    ```julia
    ```
    """
    function a() end
    end
    module foo
    """
    ```julia-repl
    julia> Base.@kwdef struct Foo
        x::Int
        y::Int
    end
    ```
    """
    function a() end
    end

And some cases where the error does not happen:

    module foo
    """
    ```julia
    1
    ```
    """
    function a() end
    end
    module foo
    """
    ```julia-repl
    julia> 1
    1
    ```
    """
    function a() end
    end
commented

what are your options set to?
