Emacs折叠模式错误

发布于 2024-09-16 18:40:46 字数 566 浏览 9 评论 0原文

我希望能够使用 http://www.emacswiki 中的 Folding.el 提供的 emacs 折叠模式.org/emacs/FoldingMode

我将以下内容放入我的 .emacs 文件中：

(setq load-path (cons (concat (getenv "HOME") "/.emacs.d") load-path))
(load "folding")
(folding-mode-add-find-file-hook)
(folding-add-to-marks-list 'latex-mode   "%{"  "%}"  nil t)

然后，当我选择一个区域并运行时，

M-x folding-fold-region

我收到错误

Wrong type argument: char-or-string-p, nil

I want to be able to use the emacs folding mode provided by folding.el from http://www.emacswiki.org/emacs/FoldingMode

I put the following in my .emacs file:

(setq load-path (cons (concat (getenv "HOME") "/.emacs.d") load-path))
(load "folding")
(folding-mode-add-find-file-hook)
(folding-add-to-marks-list 'latex-mode   "%{"  "%}"  nil t)

Then, when I select a region and run

M-x folding-fold-region

I get the error

Wrong type argument: char-or-string-p, nil

有两个问题：

您不必重新声明乳胶模式的标记，因为这已经在 folder.el 第 4411 行。因此，您应该删除行 (folding-add-to-marks-list 'latex-mode "%{" "%}" nil t)
您收到错误 类型错误参数：char-or-string-p, nil（当未启用folder-mode 时）。默认情况下，添加行 (folding-mode-add-find-file-hook) 不足以在 folder-mode 中打开文件。要以文件夹模式打开，您还应该将折叠文件局部变量放在要打开的文件的第一行，例如在 lisp 中：< /p>

;; -*- folded-file: t; -*-

：这个局部变量，以及 .emacs 中的 (folding-mode-add-find-file-hook) 命令，folder-mode 是启用后，在区域上调用 folding-fold-region 时不再有问题。

执行 Ch f folding-mode-add-find-file-hook RET 对此进行解释机制。

There are two problems :

you don't have to re-declare marks for latex-mode as this is already done in folder.el line 4411. Thus you should remove the line (folding-add-to-marks-list 'latex-mode "%{" "%}" nil t)
You get the error Wrong type argument: char-or-string-p, nil when the folder-mode is not enabled. Adding the line (folding-mode-add-find-file-hook) is not enough to open a file in folder-mode by default. To open in folder-mode, you should also place the folded-file local variable in the first line of the file you want to open, for example, in lisp :

;; -*- folded-file: t; -*-

With this local variable, and the (folding-mode-add-find-file-hook) command in your .emacs the folder-mode is enabled and you don't have problem anymore when calling folding-fold-region on a region.

Do a C-h f folding-mode-add-find-file-hook RET to have the explanation of this mechanism.
