如何创建Emacs SQL缓冲区?

我可以通过执行以下操作手动连接:

M-X SQL Postgres

并键入用户、数据库、主机、服务器

我想做些类似的事情:

(连接foo(用户“me”)(数据库“bar”)(主机“earth”))

目前的解决方案:

我从sql.el中获取了一些代码并对其进行了更改,以便可以非交互地使用它。

(defun sql-create-buffer (profile)
  "derived from sql-product-interactive in sql.el which is"
  "covered by GNU General Public License version 3."

  (setq sql-user     (cdr (assoc 'user profile))
        sql-password (cdr (assoc 'password profile))
        sql-server   (cdr (assoc 'server profile))
        sql-database (cdr (assoc 'database profile)))
  (setq product 'postgres) ;;(cdr (assoc 'product profile)))
  (when (sql-product-feature :sqli-connect product)
    (if (comint-check-proc "*SQL*")
    (pop-to-buffer "*SQL*")
      ;; Connect to database.
      (message "Login...")
      (funcall (sql-product-feature :sqli-connect product))
      ;; Set SQLi mode.
      (setq sql-interactive-product product)
      (setq sql-buffer (current-buffer))
      (sql-interactive-mode)
      ;; All done.
      (message "Login...done")
      (pop-to-buffer sql-buffer))))

(setq bar-profile '(
      (product  . "postgres")
      (user     . "me")
      (password . "")
      (server   . "earth")
      (database . "bar")))

我不知道该怎么处理'product'参数,所以我暂时把它硬编码了。 这是“sql.el中的postgres”。

(sql-create-buffer bar-profile)
