Add formatter rule to normalize keyword-argument sugar

[ultimatile]

Julia supports keyword-argument syntax sugar where a bare identifier (or dot expression) after ; implies the keyword name:

When a bare identifier or dot expression occurs after a semicolon, the keyword argument name is implied by the identifier or field name. For example plot(x, y; width) is equivalent to plot(x, y; width=width) and plot(x, y; options.width) is equivalent to plot(x, y; width=options.width).

(quoted from the Julia manual: https://docs.julialang.org/en/v1/manual/functions/#Keyword-Arguments)

Both styles (plot(x, y; width) and plot(x, y; width=width)) can appear in my codebases, and I would like to unify them automatically via a formatter rule.

Request

Add an option/rule to normalize this syntax:

• Prefer the sugar form: f(; x=x) → f(; x)
• Or prefer the explicit form: f(; x) → f(; x=x)

I apologize if I have overlooked existing options or prior discussions.
