Julia: How to clear console

Question

I am using Julia Studio and would like to know the command for clearing the console of text and memory like imports or variables? Something like matlabs "clc" and "clear" commands.

Answer 1

To clear the console, you can go into the shell and run clear (or cls) from there:

julia> ;
shell> clear

That's the elegant way to do that! – Nutty

ERROR: IOError: could not spawn clear: no such file or directory (ENOENT) – Penultimate

@CTZStef: your console's equivalent of UNIX's clear command must be in your path. If you are using Windows, you can try cls. What system are you using? – During

Answer 2

To clear Julia REPL, press Ctrl + L.

Nice to clear the screen, but do not free the memory. – Protonema

Answer 3

As mentioned workspace() provides a fresh Main. One can clear variables (and the screen) with the following:

function clear()
    Base.run(`clear`)
    for var in names(Main)
        try
            eval(parse("$var=0"))
        catch e
        end
    end
    gc()
end

Variable definitions are permanent but can be nulled. To free types and the like wrap them in modules. For more info see the first two questions here.

TERM environment variable not set. failed process: Process(`clear`, ProcessExited(1)) [1] – Novelty

gc() not found. This needs to be updated – Sulphurous

Answer 4

can try this:

function clc()
    if Sys.iswindows()
        return read(run(`powershell cls`), String)
    elseif Sys.isunix()
        return read(run(`clear`), String)
    elseif Sys.islinux()
        return read(run(`printf "\033c"`), String)
    end
end

use like:

clc();

In my case, read(run(powershell cls), String) is great. Thanks! – Presentable
