Feature request: add renderable for code

[adrhill]

It would be great to have something akin to RenderableText that prints highlighted Julia code.

Similar functionality seems to already exist in Term's Markdown support.

Hey,

What do you mean highlighted "Julia code"? How do you pass the code to the print function?
If you have your code as a string you can already do this:

using Term
import Term: highlight_syntax


mycode  = 
"""
# function to calculate the volume of a sphere
function sphere_vol(r)
    # julia allows Unicode names (in UTF-8 encoding)
    # so either "pi" or the symbol π can be used
    return 4/3*pi*r^3
end

# functions can also be defined more succinctly
quadratic(a, sqr_term, b) = (-b + sqr_term) / 2a

# calculates x for 0 = a*x^2+b*x+c, arguments types can be defined in function definitions
function quadratic2(a::Float64, b::Float64, c::Float64)
    # unlike other languages 2a is equivalent to 2*a
    # a^2 is used instead of a**2 or pow(a,2)
    sqr_term = sqrt(b^2-4a*c)
    r1 = quadratic(a, sqr_term, b)
    r2 = quadratic(a, -sqr_term, b)
    # multiple values can be returned from a function using tuples
    # if the return keyword is omitted, the last term is returned
    r1, r2
end

"""

Sorry for the noise, I must have missed this in the docs!
