map and pmap to fix #32

[zsunberg]

This PR will add support for both map and pmap

Primary usage will be through @showprogress, e.g.

@showprogress pmap(x->x^2, 1:10)

I have implemented the progress_map function, which uses channels to pass progress information back to the main process that prints the progress meter. It works for both map and pmap. Now I just need to modify showprogress to convert map and pmap calls into progress_map calls.

Comments welcome.

Ok, I think this is nearly ready to merge.

There is one problem - currently ProgressMeter has to be loaded on all processes for this to work. I believe this is because the anonymous function defined on line 575 apparently is defined only in the ProgressMeter module. I am not sure how to fix it.

I have put a fair amount of effort into creating concise code that works in all the cases I could think of, so I hope it can get merged soon :)

Is there an end in sight for this? Would be really useful to have it working.

It doesn't have to be perfect, for example

• https:/slundberg/PmapProgressMeter.jl

has worked in every place I've ever used it?

Not sure what the cruel joke is - this PR is v0.7 compatible. Just need a maintainer to merge it @timholy . I think there might be another package that uses the builtin julia logging that people are switching to.

[zsunberg]

@garrison are you the right one to ask to merge this?

[timholy]

Sorry for the unconscionable delay, I have too many packages that I maintain and need to ditch responsibility for some. I'll give more people rights to this one.

Turns out there were 5 people already authorized to merge PRs here, but I added you too @zsunberg.
