我刚刚在127.0.0.1 myproject.dev
shr包
即
emacs 24.5.1看起来真的很棒 - 就在我之后
当我打开任何C-x C-f anyfile.html
M-x shr-render-buffer
或emacs文件时，我可以自动shr-render-buffer致电.htm吗？
更新
我已尝试将以下内容添加到我的.emacs中：
.html但是我收到了错误：
(add-to-list 'auto-mode-alist '("[.]htm$" . shr-render-buffer))
(add-to-list 'auto-mode-alist '("[.]html$" . shr-render-buffer))
然后html文件在Fundamental模式下打开，它看起来比HTML模式更糟糕
答案 0 :(得分：2)
一旦打开html文件，您似乎想要自动运行函数shr-render-buffer。如您所说，.htm / .html的模式默认为html-mode，您可以将函数调用添加到html-mode-hook，例如：
(add-hook 'html-mode-hook '(lambda() (shr-render-buffer (current-buffer))))
正如@lawlist指出的那样，把它放在(require 'shr)之后。

因为这是emacs，所以做你想做的最难的部分是决定什么是最好的方法。这在很大程度上取决于个人品味/工作流程。我强烈建议您更详细地查看browse-url包。我使用的一件事是一个允许我在使用eww或我的默认系统浏览器之间切换的功能 - 这意味着我可以轻松地在emacs或chrome / safari /中呈现web内容。
几年前，我写了一个实用程序，它允许我在emacs中查看许多不同的文件格式，包括渲染的html。我现在很少使用它，因为doc-view几乎取代了大部分功能并且更好。但是，它确实显示了如何使用defadvice来修改视图文件功能，以便id根据文件类型执行不同的操作。请注意，由于这是旧的emacs代码和emacs已经改进，现在可能有更好的方法。我也知道'建议'的东西已被重新制作，但这些传统的东西仍然可以正常工作。应该让你开始。请注意，MS doc，docx，pdf等的功能依赖于外部可执行文件。
我首选的工作流程是编写一个函数，允许我将browse-url-browser-function重置为eww-browse-url或browse-url-default-browser并将其绑定到密钥。然后，我可以选择在emacs或外部浏览器中显示html，并利用已在browse-url中完成的所有工作。

"*Association for program convertion.
Each element has the following form:
(REGEXP SYMBOL CONVERTER SWITCHES INVERT REDIRECT-INPUT REDIRECT-OUTPUT HTML-OUTPUT)
Where:
REGEXP is a regexp to match file type to convert.
SYMBOL is a symbol to designate the fyle type.
CONVERTER is a program to convert the fyle type to text or HTML.
SWITCHES is a string which gives command line switches for the conversion
program. Nil means there are no switches needed.
INVERT indicates if input and output program option is to be
inverted or not. Non-nil means to invert, that is, output
option first then input option. Nil means do not invert,
that is, input option first then output option.
REDIRECT-INPUT indicates to use < to direct input from the input
file. This is useful for utilities which accept input
from stdin rather than a file.
REDIRECT-OUTPUT indicates to use > to direct output to the output
file. This is useful for utilities that only send output to
stdout.
HTML-OUTPUT Indicates the conversion program creates HTML output
rather than plain text."
