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.

2164 : * with many-arm switches than many-arm else-if chains.
2165 : *
2166 : * Each if-condition in this function must begin with a call of one of the
2167 : * functions Matches, HeadMatches, TailMatches, MatchesCS, HeadMatchesCS, or
2168 : * TailMatchesCS. The preprocessor gen_tabcomplete.pl strips out those
2169 : * calls and converts them into entries in tcpatterns[], which are evaluated
2170 : * by the calling loop in psql_completion(). Successful matches result in
2171 : * calls to this function with the appropriate pattern_id, causing just the
2172 : * corresponding switch case to be executed.
2173 : *
2174 : * If-conditions in this function can be more complex than a single *Matches
2175 : * function call in one of two ways (but not both!). They can be OR's
2176 : * of *Matches calls, such as
2177 : * else if (Matches("ALTER", "VIEW", MatchAny, "ALTER", MatchAny) ||
2178 : * Matches("ALTER", "VIEW", MatchAny, "ALTER", "COLUMN", MatchAny))

2180 : * else if (Matches("CREATE", "PUBLICATION", MatchAny, "FOR", "TABLE", MatchAny) &&
2181 : * !ends_with(prev_wd, ','))
2182 : * The former case is transformed into multiple tcpatterns[] entries and

2186 : * This is split out of psql_completion() primarily to separate code that

5996 : * version of the string provided in completion_ref_object. If there is a
5997 : * third '%s', it will be replaced by a suitably-escaped version of the string
5998 : * provided in completion_ref_schema. Those strings should be set up
5999 : * by calling set_completion_reference or set_completion_reference_verbatim.
6000 : * Simple queries should return a single column of matches. If "verbatim"
6001 : * is true, the matches are returned as-is; otherwise, they are taken to
6002 : * be SQL identifiers and quoted if necessary.
6003 : *
6004 : * 2. A schema query used for completion of both schema and relation names.
6005 : * This is represented by a SchemaQuery object; see that typedef for details.
6006 : *
6007 : * See top of file for examples of both kinds of query.
6008 : *
6009 : * In addition to the query itself, we accept a null-terminated array of
6010 : * literal keywords, which will be returned if they match the input-so-far
6011 : * (case insensitively). (These are in addition to keywords specified
6012 : * within the schema_query, if any.)
6013 : *
6014 : * If "verbatim" is true, then we use the given text as-is to match the
6015 : * query results; otherwise we parse it as a possibly-qualified identifier,
6016 : * and reconstruct suitable quoting afterward.
6017 : *
6018 : * "text" and "state" are supplied by Readline. "text" is the word we are
6019 : * trying to complete. "state" is zero on first call, nonzero later.
6020 : *

6023 : * that is a candidate completion. Return NULL when done.
