Good evening, dear all!
Here is the mechanism that implements this:
.
.
.
1673 /* Match the last N words before point, case-sensitively. */
1674 #define TailMatchesCS(...) \
1675 TailMatchesImpl(true, previous_words_count, previous_words, \
1676 VA_ARGS_NARGS(__VA_ARGS__), __VA_ARGS__)
.
.
.
4824 else if (TailMatchesCS("\\ds*"))
4825 COMPLETE_WITH_SCHEMA_QUERY(Query_for_list_of_sequences);
.
.
.
There is a rather large list of meta-commands that are handled by TailMatchesCS(...).
For example:
\ENCODING<TAB> autocompletes to \encoding
\eNcOdInG<TAB> autocompletes to \encoding
\dU<TAB> or \DU<TAB> autocompletes to \du
Including the command under discussion:
\CONNINFO<TAB> autocompletes to \conninfo
For the meta-commands[+], there is no autocomplete.
Regards,
Maiquel Grassi.
