Thank you! Btw I've rebased the PRs

ms: Hey, I just downloaded the docker image and installed hpx. So, since I am new to docker, I was wondering how I can use my editor to view a code file inside the docker image.
<dkaratza[m]>
While building hpx, I came up with a few ideas (in quick start guide) and I would like to try them in order to see how they render
<ms[m]>
dkaratza: you can, kind of
<ms[m]>
I recommend you use the `-v` option to docker run
<ms[m]>
with that you can say e.g. `-v=$PWD:/hpx` and $PWD or whatever you choose will be mounted at /hpx inside the container
<ms[m]>
then you can edit files normally outside the container and the changes will be visible inside the container as well
<ms[m]>
one thing to note is that if you put your build directory inside that mounted directory they'll be owned by root also outside the container
<dkaratza[m]>
alright, since I built hpx inside the docker image, shouldn't I save this image first so that I don't lose my changes?
<dkaratza[m]>
also, this option -v=$PWD:/hpx won't work for me, since I built hpx inside the docker image, right?
<ms[m]>
I'd recommend starting over with a new build directory (e.g. build under the source directory)
<ms[m]>
then the state of the build will be saved even if you shut down the container
<ms[m]>
if you're going to be making frequent changes to the actual packages inside the image it's better to create a new image, but I'd imagine you won't need that too much right now
<ms[m]>
the -v won't help after the fact (as far as I know, there might be some docker trickery that lets you do that, but nothing I know of)
<dkaratza[m]>
I cloned the hpx inside the docker image
<dkaratza[m]>
why creating the build directory under the hpx source would preserve the changes?
<gnikunj[m]>
dkaratza: I think he meant with -v flag
<ms[m]>
Ah, indeed, what gnikunj said
<ms[m]>
It's easier if you also clone hpx on the host system and then mount that inside the container
