Formatting Code

Code formatting is powered by JuliaFormatter.jl. Both the Format Document command (Ctrl-Shift-I) and Format Selection (Ctrl-K Ctrl-F) are supported.

The default formatting is fairly conservative and unintrusive, but you can customise it with a JuliaFormat.toml file in your project:

style = "blue"

[options]
margin = 92

style picks one of the presets — default, yas, blue, sciml, minimal (the default) or runic — and [options] adjusts individual settings on top of it, accepting any JuliaFormatter.jl option. You can also keep folders out of formatting altogether with exclude, or format part of the project differently. See Configuration Files for all of that.

Note: the extension does not read JuliaFormatter.jl's own .JuliaFormatter.toml. If you have one, copy its settings into JuliaFormat.toml, putting the individual options under [options].

Formatting helps to keep code readable by automatically aligning indentations and spaces.

The Julia formatter can automatically make this code:

f(x)=2x+3
print(f'( 2 ))

open("myfile.txt", "w") do io
	write(io, "Hello world!")
    end;

look like this:

f(x) = 2x + 3
print(f'(2))

open("myfile.txt", "w") do io
    write(io, "Hello world!")
end;

It's the very same code, though now it's much easier to read.
