Re: [PATCH v2 0/2] MI: Add new command -complete

[Pedro Alves <palves at redhat dot com>]

I'm totally not against this new command at all, but I have to say that I'd be
much more thrilled if someone just spent the time to make separate CLI/MI
channels work on Windows too.  The channel doesn't _have_ to be a PTY.

Jan, please consider the wildmatching case.  E.g., when debugging GDB itself:

(gdb) b push_bac<TAB>
Display all 102 possibilities? (y or n)
debug_names::offset_vec_tmpl<unsigned int>::push_back_reorder(unsigned long)
debug_names::offset_vec_tmpl<unsigned long>::push_back_reorder(unsigned long)
std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >::push_back(char)
...

The frontend needs to complete "b push_bac" -> "b push_back", and present
the matches.

But the least common denominator is not at the start of the matches
strings.  How will a frontend compute the LCD from the matches list alone?

Please mind the "2018" copyright year in the testcase.

Thanks,
