如何创建Emacs SQL缓冲区？

Question

我可以手动连接:

Mx sql-postgres

并键入用户,数据库,主机,服务器

我想做点什么:

(connect-foo(用户"我")(数据库"bar")(主机"地球"))

目前解决方案:

我从sql.el中获取了一些代码并对其进行了更改,以便我可以非交互式地使用它.

(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")))

我不知道如何处理'product'参数,所以我现在把它硬编码了.这是'sql.el中的postgres.

(sql-create-buffer bar-profile)

似乎打包不是非交互式使用(可能是为了阻止将登录信息写入init文件,这是一个完美的原则).

但是,如果您真的想避免回答问题,可以简单地重新定义查询功能,如下所示:

(defun sql-get-login (&rest what)
  (setq sql-user     "me"
        sql-password "secret"
        sql-server   "localhost"
        sql-database "MyDB"))
