17 : * This file implements a somewhat more sophisticated readline "TAB
18 : * completion" in psql. It is not intended to be AI, to replace
19 : * learning SQL, or to relieve you from thinking about what you're
20 : * doing. Also it does not always give you all the syntactically legal
21 : * completions, only those that are the most common or the ones that
22 : * the programmer felt most like implementing.
23 : *
24 : * CAVEAT: Tab completion causes queries to be sent to the backend.
25 : * The number of tuples returned gets limited, in most default
26 : * installations to 1000, but if you still don't like this prospect,
27 : * you can turn off tab completion in your ~/.inputrc (or else
28 : * ${INPUTRC}) file so:
29 : *
30 : * $if psql
31 : * set disable-completion on
32 : * $endif
33 : *
34 : * See `man 3 readline' or `info readline' for the full details.
35 : *
36 : * BUGS:
37 : * - Quotes, parentheses, and other funny characters are not handled
38 : * all that gracefully.

2129 : * a loop in psql_completion()). Compilers tend to be more ready to deal
2130 : * with many-arm switches than many-arm else-if chains.
2131 : *
2132 : * Each if-condition in this function must begin with a call of one of the
2133 : * functions Matches, HeadMatches, TailMatches, MatchesCS, HeadMatchesCS, or
2134 : * TailMatchesCS. The preprocessor gen_tabcomplete.pl strips out those
2135 : * calls and converts them into entries in tcpatterns[], which are evaluated
2136 : * by the calling loop in psql_completion(). Successful matches result in
2137 : * calls to this function with the appropriate pattern_id, causing just the
2138 : * corresponding switch case to be executed.
2139 : *
2140 : * If-conditions in this function can be more complex than a single *Matches
2141 : * function call in one of two ways (but not both!). They can be OR's
2142 : * of *Matches calls, such as
2143 : * else if (Matches("ALTER", "VIEW", MatchAny, "ALTER", MatchAny) ||
2144 : * Matches("ALTER", "VIEW", MatchAny, "ALTER", "COLUMN", MatchAny))
2145 : * or they can be a *Matches call AND'ed with some other condition, e.g.
2146 : * else if (Matches("CREATE", "PUBLICATION", MatchAny, "FOR", "TABLE", MatchAny) &&
2147 : * !ends_with(prev_wd, ','))
2148 : * The former case is transformed into multiple tcpatterns[] entries and

2151 : *
2152 : * This is split out of psql_completion() primarily to separate code that

5682 : * provided in completion_ref_schema. Those strings should be set up
5683 : * by calling set_completion_reference or set_completion_reference_verbatim.
5684 : * Simple queries should return a single column of matches. If "verbatim"
5685 : * is true, the matches are returned as-is; otherwise, they are taken to
5686 : * be SQL identifiers and quoted if necessary.
5687 : *
5688 : * 2. A schema query used for completion of both schema and relation names.
5689 : * This is represented by a SchemaQuery object; see that typedef for details.
5690 : *
5691 : * See top of file for examples of both kinds of query.
5692 : *
5693 : * In addition to the query itself, we accept a null-terminated array of
5694 : * literal keywords, which will be returned if they match the input-so-far
5695 : * (case insensitively). (These are in addition to keywords specified
5696 : * within the schema_query, if any.)
5697 : *

5702 : * "text" and "state" are supplied by Readline. "text" is the word we are
5703 : * trying to complete. "state" is zero on first call, nonzero later.
