add initial support for easyrsa bash completion

[eric-belhomme]

Hello,

The easyrsa CLI is powerful but a bit tricky to use as it support many arguments. Even worst, positional arguments matters !
That's why a started to write a bash completion function to ease daily easyrsa usage.

As I wonder this could be helpful for many others users I propose this PR.

To use it, just source easyrsa.completion from your ~/.bashrc:

source easyrsa3/easyrsa.completion

Then enjoy !
Eric

Hello, Thanks for the link, I didn't knew that tool ! I made a first pass. There is still some warnings related to the way the $COMPREPLY array is built, but that's the usual method seen everywhere on bash completion scripts so I prefer keep it untouched.

@eric-belhomme easyrsa has some new commands:

• show-expire, show-revoke, show-renew and renewable
• revoke-renewed and rewind-renew

Could you please add those to the script ?

The patch to add these new options would also help to serve as documentation of how to do this in future.

If you can support bash completion for EasyRSA then, please, feel free to reopen.

Until then, closed as not planned.

As soon as I closed this I changed my mind. Sorry for the noise.

Re-opened as "would really like this but want help".

I have put a lot of work into EasyRSA, so there were a lot of changes.
This made it difficult to provide bash-completion out-of-the-box.

Now that EasyRSA version 3.1 is stabilizing, bash-completion is a viable addition.
