如何有效搜索信息文档？ [英] How to efficiently search Info documentation?

问题描述

我正在寻找有关 tr 程序的文档。正如你所想象的，人物 t 和 r 的组合在英语中经常发生...虽然我确定关于这个名字，我不知道它所属的部分的名称，所以我不得不显示所有的节点，并尝试搜索像 tr 或 tr（等等。

没有更好的方法吗？

解决方案

嗯，我只能猜测以下不是为你而发生的;但是个别程序的节点真的应该列在顶级目录中，因此在您输入 Mx 信息时显示。 RET d ，您可以从中简单地使用 m tr RET 。

但是，如果您正在搜索不在任何目录文件中的东西，我唯一方便的是 Mx info- apropos （搜索所有的索引而不是节点标题）。

当然，在给定的手册中，您可以使用 I 来搜索其索引，这是更快而不是搜索所有这些。

编辑：这是切向的，但即将到来的Emacs 24.4（目前在NEWS文件中未记录） ）在非当前手册中完成Info节点名称。

eg 我 g （elisp） TAB 现在提供即使您当前没有查看该手册，也可以在elisp手册中的所有节点完成。

这是一个非常欢迎更改！ / p>

I was looking for documentation on tr program. As you would imagine the combination of characters t and r happens fairly often in English language... Although I was sure about the name, I wasn't sure about the name of the section it belongs to, so I had to display all nodes and try searching for something like tr or tr( and so on.

Isn't there a better way to do it?

解决方案

Hmm... I can only guess that the following isn't happening for you; however nodes for individual programs really ought to be listed in the top-level directory, and hence show up when you type M-x info RETd, from where you can simply use m tr RET.

However if you're searching for something which isn't in any of the directory files, the only convenient thing I know of is M-x info-apropos (which searches all of the indexes rather than the node titles).

And of course within a given manual you can use I to search its index, which is much faster than searching all of them.

Edit: This is tangential, but an excellent improvement in the upcoming Emacs 24.4 (currently undocumented in the NEWS file) is completion for Info node names in non-current manuals.

e.g. C-hig (elisp) TAB now provides completions for all the nodes in the elisp manual, even if you are not currently viewing that manual.

This is an extremely welcome change!
