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.

2150 : * with many-arm switches than many-arm else-if chains.
2151 : *
2152 : * Each if-condition in this function must begin with a call of one of the
2153 : * functions Matches, HeadMatches, TailMatches, MatchesCS, HeadMatchesCS, or
2154 : * TailMatchesCS. The preprocessor gen_tabcomplete.pl strips out those
2155 : * calls and converts them into entries in tcpatterns[], which are evaluated
2156 : * by the calling loop in psql_completion(). Successful matches result in
2157 : * calls to this function with the appropriate pattern_id, causing just the
2158 : * corresponding switch case to be executed.
2159 : *
2160 : * If-conditions in this function can be more complex than a single *Matches
2161 : * function call in one of two ways (but not both!). They can be OR's
2162 : * of *Matches calls, such as
2163 : * else if (Matches("ALTER", "VIEW", MatchAny, "ALTER", MatchAny) ||
2164 : * Matches("ALTER", "VIEW", MatchAny, "ALTER", "COLUMN", MatchAny))

2172 : * This is split out of psql_completion() primarily to separate code that

5980 : * output LIKE '%s'

5984 : * version of the string provided in completion_ref_object. If there is a
5985 : * third '%s', it will be replaced by a suitably-escaped version of the string
5986 : * provided in completion_ref_schema. Those strings should be set up
5987 : * by calling set_completion_reference or set_completion_reference_verbatim.
5988 : * Simple queries should return a single column of matches. If "verbatim"
5989 : * is true, the matches are returned as-is; otherwise, they are taken to
5990 : * be SQL identifiers and quoted if necessary.
5991 : *
5992 : * 2. A schema query used for completion of both schema and relation names.
5993 : * This is represented by a SchemaQuery object; see that typedef for details.
5994 : *
5995 : * See top of file for examples of both kinds of query.
5996 : *
5997 : * In addition to the query itself, we accept a null-terminated array of
5998 : * literal keywords, which will be returned if they match the input-so-far
5999 : * (case insensitively). (These are in addition to keywords specified
6000 : * within the schema_query, if any.)
6001 : *
6002 : * If "verbatim" is true, then we use the given text as-is to match the
6003 : * query results; otherwise we parse it as a possibly-qualified identifier,
6004 : * and reconstruct suitable quoting afterward.
6005 : *
6006 : * "text" and "state" are supplied by Readline. "text" is the word we are
6007 : * trying to complete. "state" is zero on first call, nonzero later.
6008 : *
6009 : * readline will call this repeatedly with the same text and varying

6011 : * that is a candidate completion. Return NULL when done.
