Get the expanded string of entire command executed even if entered string is partial

[DeekshaBhandary]

cli> show list1 ?
value1
data1
string1
cli> show list1 s  <Enter>

cv_string_get(cvec_i(cvv, 0)); this method returns "show list1 s" instead of "show list1 string1" in the above case
Should be able to retrieve the entire string

I am not sure. If you inspect the cvv argument, you see the following:

(gdb) p cvec_print(stderr,cvv)
0 : cmd = show list1 s
1 : show = "show"
2 : list1 = "list1"
3 : string1 = "string1"

The first argument is the string as entered by the user. Since the user entered "s", that is returned.
If you want the third argument, you can get it via cv_string_get(cvec_i(cvv,3)) in that example.

One can also construct a string from the argv[1]..argv[3] that corresponds to the string you need.

Added a replacement of the cvv[0] cmd parameter from the original string to the expanded string.
However it turned out the expanded string depended on excludekeys settings and needed to be reverted.
Need somewhat larger take and will have to wait.

There is now a solution to this issue.
To get the behavior requested in this ticket, you need to call: cligen_expand_first_set(h,1)
Please see also cligen_tutorial Section 6.1
Please verify the solution

[olofhagsand]

To clarify, to test it, you need to initialize it properly, such as call cligen_expand_first_set(cli_cligen(h), 1) at some point in main() in apps/cli/cli_main.c and recompile. No specific config option is added yet.
