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.

2105 : * a loop in psql_completion()). Compilers tend to be more ready to deal
2106 : * with many-arm switches than many-arm else-if chains.
2107 : *
2108 : * Each if-condition in this function must begin with a call of one of the
2109 : * functions Matches, HeadMatches, TailMatches, MatchesCS, HeadMatchesCS, or
2110 : * TailMatchesCS. The preprocessor gen_tabcomplete.pl strips out those
2111 : * calls and converts them into entries in tcpatterns[], which are evaluated
2112 : * by the calling loop in psql_completion(). Successful matches result in
2113 : * calls to this function with the appropriate pattern_id, causing just the
2114 : * corresponding switch case to be executed.
2115 : *
2116 : * If-conditions in this function can be more complex than a single *Matches
2117 : * function call in one of two ways (but not both!). They can be OR's
2118 : * of *Matches calls, such as
2119 : * else if (Matches("ALTER", "VIEW", MatchAny, "ALTER", MatchAny) ||
2120 : * Matches("ALTER", "VIEW", MatchAny, "ALTER", "COLUMN", MatchAny))
2121 : * or they can be a *Matches call AND'ed with some other condition, e.g.
2122 : * else if (Matches("CREATE", "PUBLICATION", MatchAny, "FOR", "TABLE", MatchAny) &&
2123 : * !ends_with(prev_wd, ','))
2124 : * The former case is transformed into multiple tcpatterns[] entries and

2126 : * transformed into a case label and a contained if-statement.
2127 : *
2128 : * This is split out of psql_completion() primarily to separate code that

5597 : * third '%s', it will be replaced by a suitably-escaped version of the string
5598 : * provided in completion_ref_schema. Those strings should be set up
5599 : * by calling set_completion_reference or set_completion_reference_verbatim.
5600 : * Simple queries should return a single column of matches. If "verbatim"
5601 : * is true, the matches are returned as-is; otherwise, they are taken to
5602 : * be SQL identifiers and quoted if necessary.
5603 : *
5604 : * 2. A schema query used for completion of both schema and relation names.
5605 : * This is represented by a SchemaQuery object; see that typedef for details.
5606 : *
5607 : * See top of file for examples of both kinds of query.
5608 : *
5609 : * In addition to the query itself, we accept a null-terminated array of
5610 : * literal keywords, which will be returned if they match the input-so-far
5611 : * (case insensitively). (These are in addition to keywords specified
5612 : * within the schema_query, if any.)
5613 : *

5616 : * and reconstruct suitable quoting afterward.

5618 : * "text" and "state" are supplied by Readline. "text" is the word we are
5619 : * trying to complete. "state" is zero on first call, nonzero later.
5620 : *
