run(window, code) should support JSONText

[hhaensel]

Currently run() for Electron windows is defined as

function Base.run(win::Window, code::AbstractString)
# <...>
end

It would be great to also support JSONText, as that would allow for js-Syntax-Highlighting in VS-Code

Base.run(w::Window, code::JSON.JSONText) = run(w, JSON.json(code))

run(win, js"""
    console.log('This looks pretty!')
""")

Oh, and you have to define the macro js_str

macro js_str(expr)
  :( JSONText($(esc(expr))) )
end

[hhaensel]

And to support string interpolation we could even

macro js_str(s)
  :( JSONText($(esc(s))) )
end

macro js_str(s, flags)
  flags == "i" || @warn "Only 'i' flag currently supported (string interpolation)."
  if 'i' in flags
    :( JSONText($(esc(Meta.parse("\"$s\"")))) )
  else
    :( JSONText($(esc(s))) )
  end
end

and then

julia> js"hello $(1+2)"i
"JSONText(hello 3)"

or more complicated

julia> js"""Say $("1-$(5-3)" * "-3")"""i
JSONText("Say 1-2-3")

EDIT: update macro with correct brackets
EDIT 2: else case of 'i' in flags
EDIT 3: remove escape_string() and keep JSONText outside the escaped expression

I got lost, wrong repo.
Terrribly sorry.

[hhaensel]

Well, I DID get lost.
The first part should indeed be part of this repo, the js macro part should most probably be defined in JSON.jl
So @davidanthoff or @SimonDanisch please reopen, if this seems interesting for you.

[hhaensel]

I'll submit the js macro definition to a PR in JSON.jl
