Possible issue with climaformat.jl after Merge 1172

[smarras79]

Description

The commit listed below (Merge #1172) has possibly broken climaformat.jl as shown in the error trace posted below the commit:

commit 7f9d08dc66c1c0068c57b4f7778b7f68000bab3f (origin/master, origin/HEAD, master)
Merge: 03850273a 6e1b7786b

    Merge #1172

Steps to reproduce

Steps to reproduce the behavior:

1. Output of git log -1. In the case of bugs from code that has significantly diverged from master, a separate branch can be created and linked.

commit bfbf19eff9aaf57b84cc16556d65953fb4437aa3 (HEAD -> sm/mountain-waves, origin/sm/mountain-waves)

Date:   Wed May 27 03:36:43 2020 -0700

    Mountain gravity waves:
    - hydrostatic linear and non-linear setups
    - removed agnesi-equilibrium.jl. IT will be added with its own PR.
    - Smagorinsky run with  0.23
    - Formatted
    - Reduced time end to avoid wave issue after the flow went through a few times
    - Replaced ClimateMachine.init() with ClimateMachine.cli() after merging with 7f9d08dc66c1c0068c57b4f7778b7f68000bab3f

This is PR #1163

2. Exact sequence of commands run (REPL, terminal, or script) to reproduce this issue issue.
3. Expected runtime for issue/bug to reveal itself (particularly useful in the case of problems with physics / set-ups that require longer time to solution)

Expected behavior

A clear and concise description of what you expected to happen.

Problem is with the file not the formatter

ClimateMachine.cli ()

should have no space

ClimateMachine.cli()

in tutorials/Atmos/agnesi_hs_lin.jl

[smarras79]

Shouldn't the formatter identify these issues and fix them?

[smarras79]

issues solved.

Shouldn't the formatter identify these issues and fix them?

The formatter only works on syntactically correct julia code. It cannot fix bugs

[jkozdon]

fair enough, but a space after before a parenthesis is not a bug in the real sense. It is a syntax error due to a wrong format of the text in the file. Anyway, that solved it.

A space before a parenthesis is a bug in julia. Since the code won't run.

julia> f() = nothing
f (generic function with 1 method)

julia> f ()
