我为什么需要首先在座标上 by子的次要功能时,打上C-u 0。
原标题:Why do I need to type c-u 0 first when I call byte-recompile-directory function in emacs?

我正在安装“org-mode”。 某个地方的辅导网告诉我,我应当采取这些步骤:c-u 0 m-x byte-recompile-directory<RET>。 我知道我正在采取什么步骤(m-x byte-recompile-directory<RET>,但此处的含义是什么? 感谢!

最佳回答

From the byte-recompile-directory documentation:

If the .elc file does not exist, normally this function does not compile the corresponding .el file. However, if the prefix argument ARG is 0, that means do compile all those files. A nonzero ARG means ask the user, for each such .el file, whether to compile it. A nonzero ARG also means ask about each subdirectory before scanning it.

C-u是向互动职能提供数字论据的通常方式。 除非你提供C-u 0的零动力,否则没有.elc的卷宗就重新编造。
