Re: [HACKERS] Todo claim: psql tab completion on schema names

As this seems to fall under the todo item Allow psql to do table completion for SELECT * FROM schema_part and table completion for SELECT * FROM schema_name I would like if possible to claim this, at least for a week or so. I've been debating a mechanism which could build tab completion tables based on the documentation for a while now -- and was going to give it a try next week. If it works, that file would essentially disappear. It doesn't really change what happens, just the approach. The end goal being a backend independent psql. In this respect couple of general questions: - is there any reason why tab expansion of slash commands is only implemented in a few cases? E.g. for \d but not \di ? . is there any requirement to maintain any kind of backwards compatibilty to pre 7.3 clients? Post 7.3 launch most of these cases were cleaned up, not to say some weren't missed. You might want to take a look at CVS-TIP sources. Feel free to send in patches for ones that have been missed. - pg_catalog.pg_table_is_visible() works on non-table relations as well, right? I would assume so, but haven't checked. -- Rod Taylor [EMAIL PROTECTED] PGP Key: http://www.rbt.ca/rbtpub.asc signature.asc Description: This is a digitally signed message part

How impossible would it be to generate the tab-completion from the _grammar_ (for the SQL) rather than from docs? Something I was musing about when adding cases to this a month or so ago.

Send in the patches: won't hurt, even if they get overridden by alter work - who knows, Rod may get distracted and not complete the grand plan above. In general, it's better to capture existing work than hold of for future, better, implementations, for things like this (no backwards compatability issues) Ross ---(end of broadcast)--- TIP 1: subscribe and unsubscribe commands go to [EMAIL PROTECTED]

Grammer would certainly be nicer but vastly more complicated. Parsing the SGML shouldn't be overly difficult. Perhaps I'll just clean up what I've done -- move describe.c to the backend -- and see how to approach tab completion later.
