add CLI

[paolostivanin]

Currently, there's no way to use OTPClient on a system without a desktop environment (e.g. server).
As many of you asked for this feature, I'm gonna go ahead and implement it. This will take some time though because the implementation most likely will involve some refactoring.

• design
  • part of v2.0
  • simple terminal interface
• implementation
  • show option
  • list option
• testing

I'm a big supporter of this feature! :)
And if I can help I will happily do.
In my view the best would be a simple terminal interface via regular command line parameters, no ncurses should be needed (of course there will be limitations for importing, e.g. no webcam scanning :))

Help is always appreciated 😄 currently, I don't have a clear idea about how to implement this feature. The only sure thing is that I have to refactor the existing code because it's tightly coupled to GTK+ at the moment.
I will write here once this feature is ready to be implemented and, therefore, contributors can start helping 👍

otpclient-cli will have the following options:

• version
• help
• list
• show

The list option will simply list all the items in the following form:

Account | Issuer
testAccount, myself
testAccount2, myself2
...

---

The show option will accept the following parameters:

• -a (account): mandatory if issuer is not specified, optional otherwise
• -i (issuer): mandatory if account is not specified, optional otherwise
• -m: match exactly (only output if given string is matched)

Example:
otpclient-cli show -a testAccount

The following entries have been found:
1) testAccount
2) testAccount2
3) TestAccOUNT
Type the number to show: 2
Account:    testAccount2
Issuer:     myself2
OTP:        234123
Validity:   19s

I like the proposed idea a lot!
If I understand it correctly, you would be able to get the next token by issuing: "otpclient-cli show -a testAccount" directly, with no interactive selection, right?

Another minor question : is it possible to see also the currently displaying token sequence number?

And thanks!

• otpclient-cli show -a testAccount would show the current valid OTP value
• otpclient-cli show -a testAccount will require no input if there are no other matching accounts (testACCOUNT, teSTaccOunt, etc). Otherwise, you have to use -m if you want to be sure not to have interactive input
• good idea, I can implement also a "show current otp and next one"

I'm still not sure whether I should develop a feature complete CLI version or not 🤔
If I do that, for every thing I do for the GUI version I'd have to do it also for the CLI version. This means double work and double maintenance (on mt scarce free time) because not all the code can be reused, unfortunately.
What is your exact use case for the CLI @tentator ? A 1 to 1 copy of the GUI version or just a subset would be enough? (e.g. show and list)

[tentator]

I'd say that a functional minimal set is more than enough.. I'd even be satisfied with GUI only import but CLI show. In the end the problem is that there is nothing available elsewhere working from CLI.

[paolostivanin]

For now I'll implement only show and list then 👍

[tentator]

It works!! Thank you!!

[paolostivanin]

You already compiled and installed it? :D you're fast 🤣
Glad to hear that it's working 👍

[tentator]

you can bet on it.. was long waiting for.. I'm planning to use some ansible magic on top of it, will let you know how it coasts! :)

[paolostivanin]

ansible? :D now I'm curios to hear your use case ;)
