Is there a function for printing the REPL content to a file in Julia language?
If those outputs have already been printed in the REPL, I guess the only way to save them to a file is copy-pasting manually. But if you would like to save the REPL output history for future use, one way is to overload display
:
shell> touch repl_history.txt
julia> using REPL
julia> function REPL.display(d::REPL.REPLDisplay, mime::MIME"text/plain", x)
io = REPL.outstream(d.repl)
get(io, :color, false) && write(io, REPL.answer_color(d.repl))
if isdefined(d.repl, :options) && isdefined(d.repl.options, :iocontext)
# this can override the :limit property set initially
io = foldl(IOContext, d.repl.options.iocontext,
init=IOContext(io, :limit => true, :module => Main))
end
show(io, mime, x)
println(io)
open("repl_history.txt", "a") do f
show(f, mime, x)
println(f)
end
nothing
end
then, let's print something random in the REPL:
julia> rand(10)
10-element Array{Float64,1}:
0.37537591915616497
0.9478991508737484

help?> gcd
search: gcd gcdx significand
gcd(x,y)
Greatest common (positive) divisor (or zero if x and y are both zero).
Examples
≡≡≡≡≡≡≡≡≡≡
julia> gcd(6,9)
3
julia> gcd(6,-9)
3
And here is what the file content looks like:
shell> cat repl_history.txt
10-element Array{Float64,1}:
0.37537591915616497
0.9478991508737484

If there is no need to work with REPL interactively, simply use julia script.jl > output.txt
might also do the trick.
