Progress meter for long-running computations

ProgressMeter.jl

Progress meter for long-running operations in Julia

Installation

Within julia, execute

Pkg.add("ProgressMeter")

Usage

This works for functions that process things in loops. Here's a demonstration of how to use it:

using ProgressMeter

function my_long_running_function(filenames::Array)
    n = length(filenames)
    p = Progress(n, 1)   # minumum update interval: 1 second
    for f in filenames
        # Here's where you do all the hard, slow work
        next!(p)
    end
end

You should see a green status line that indicates progress during this computation, including ETA and final duration.

If your computation runs so quickly that it never needs to show progress, no extraneous output will be displayed.

Optionally, a description string can be specified which will be prepended to the output, and a progress meter M characters long can be shown. E.g.

p = Progress(n, 1, "Computing initial pass...", 50)

will yield

Computing initial pass...53%|###########################                       |  ETA: 0:09:02

in a manner similar to python-progressbar.
