Default input handler without specifying a command

[wangxuw]

Like the switch grammar, how about register a default handler for input?
For example: just input three integers after the prompt, and then call the Add command by default.

cli> 1 2 3
6
cli>

It would be nice when a single command is massively used.

BTW, cli now supports Insert a command name of std::string(""), but it seems this command would never be called.

Since the library uses the first token of the input to lookup a command list, I could add a default handler to manage the cases where the command is unknown or wrong. However, this would comprise also the errors in the types of command parameters.
I'm not quite sure this would constitute a useful feature, however.

[wangxuw]

Yes, of course. It would also be conflict with some commands. e.g: command 1 in aforementioned example.

I think the Insert of command std::string("") should be disabled since it is never called.

BTW, it is somewhat weird when paste something to runtime cli using ctrl-v, the whole content would not echo until a next keyboard is triggered.

cli/include/cli/detail/linuxkeyboard.h

Line 79 in e649e95

std::pair<KeyType,char> Get()

should here be modified to echo pasted content?

Ok, @EFS86340 .
So this issue should be actually split into three:

1. custom default input handler
2. do not allow the insertion of empty command in a menu (i.e., "")
3. missing echo after ctrl-v paste of command

Can you open the issue 2) and 3) please? So that we can continue the discussion of each problem the in the appropriate place :-)

Thank you

Sure, so I would close this issue now.
