Question about cligen supporting command line scope/level

[mgimza]

When a user provides a valid incomplete command, is it possible for cligen to put the user into the scope/level of the syntax structure of that command rather than returning the "Unkown command" error message ?

For example, given the following syntax....
aa {
bb;
cc;
dd {
ee;
}
}

The user types the command : "aa\n" . Cligen would then not return "Unknown Command", but allows the user to perform the commands defined inside the "aa" block at the next prompt. The prompt could contain the current scope/level of the command.

cli>aa
cli(aa)>dd
cli(aa/dd)>ee

Thanks,
Marek Gimza

The building-blocks for this behavior exists, but is only partly made in cligen-only context. See "tree workpoints" in Section 2.7.2 in the cligen-tutorial.

See also the yang-based solution made in clixon, such as in https://clixon-docs.readthedocs.io/en/latest/cli.html#the-auto-cli
where the syntax is made on a YANG specification.

Thanks Olofhagsand ... my apologies for not replying sooner. I have taken a look and will give your proposal a try :)
