如何使Emacs sql模式识别MySQL＃评论？ [英] How to make Emacs sql-mode recognize MySQL #-style comments?

问题描述

我正在读一堆使用＃（到行尾）注释的MySQL文件，但是我的sql模式不支持它们。我发现sql.el的语法表部分定义/ ** /和 - 评论，但根据这，Emacs语法表只支持2种注释样式。

I'm reading a bunch of MySQL files that use # (to end-of-line) comments, but my sql-mode doesn't support them. I found the syntax-table part of sql.el that defines /**/ and -- comments, but according to this, Emacs syntax tables support only 2 comment styles.

有一种方法可以在sql中添加＃注释。 el容易吗？

Is there a way to add support for # comments in sql.el easily?

推荐答案

Rolf的答案似乎不适合我。备选注释样式的用于开始注释的字符类别AFAIK应该是< b，而不是b。这是我使用的：

The answer by Rolf did not seem to work for me. AFAIK, the character class for starting comments, of the alternative comment style should be "< b", not " b". This what I use:

    (add-hook 'sql-mode-hook 'my-sql-mode-hook) 
    (defun my-sql-mode-hook ()   
      ;; Make # start a new line comment in SQL. This is MySQL-specific
      ;; syntax.
      (modify-syntax-entry ?# "< b" sql-mode-syntax-table))
