Removing bash prompt

[jonocodes]

Something came up while working on PWDer. here is an idea. if a line in an input block starts with '$ ', then '$ ' would get removed before executing it. This way the markdown can follow the Docker/Arch documentation guidelines a little closer. https://docs.docker.com/opensource/doc-style/#code-and-ui-text-styling

For example if there is '$ docker ps' in the exec block, and it is clicked then 'docker ps' would be executed.

hmm I not sure if I agree with the change, what if you want to execute something like $mybinary?
I prefer to be clear and make sure that the command will execute "as is" in the code block

So we are talking about having an sdk for pwd and and sdk for the tutorials. The tutorials sdk manages the click event of the code snippets and passes them to the pwd sdk to exec on the instance.
I think this logic of removing the starting $ would be implemented on the tutorials sdk.

@marcosnils are you concerned that someone want to write a tutorial where he wants you to run:
$mybinary?
If that is the case, then following the guidelines he would have to put int the <code> tag:

<code>
$ $mybinary
</code>

Which is basically what you would see in your shell, right?

@xetorthio makes sense.

Ok, if this is the "standard" way of defining terminal commands per the styling guides as @jonocodes mentioned, let's go ahead and make the changes 👍

My proposal is to remove only '$ ' (note the space) if it is at the beginning of a line. A space following the dollar would be required if it were to be removed. Here is an example

$ ping google.com
$mybinary
 $ ping google.com

would be interpreted and executed as

ping google.com
$mybinary
 $ ping google.com

The space before the $ might need to be discussed more though. Maybe its ok to strip it actually.

Also good to think about how to deal with '# ' lines. Guidelines say this should be interpreted as a root operation. I know those get confused with comments, but I think in this case its not ambiguous.

I can take a stab at implementing this, but I'll wait for a little more discussion on the proposal.
