Aha. I like the idea, though I prefer to use the buffer name rather than the header. Aquamacs’ tabbar-mode takes the header over, so if you set anything there, the tabs break.

I’m definitely appropriating the concept, though.

I find this handy — it puts the SQL server’s name, and the database name, in the header line:

(defun sql-update-header-line ()
(setq header-line-format
‘(:propertize
(“” sql-server “:” sql-database)
face highlight)))

(defun sql-update-db-from-input (input)
(when (string-match (rx bos “use”
(one-or-more blank)
(group (one-or-more graphic))
(zero-or-more blank)
“;”)
input)
(setq sql-database (match-string 1 input) )
(sql-update-header-line)))

(add-hook ’sql-interactive-mode-hook
(lambda ()
;; so I don’t forget what db I’m connected to!
(set (make-local-variable ‘comint-input-filter-functions)
(list ’sql-update-db-from-input))
(sql-update-header-line)))
