How can I post a block of Emacs Lisp code?
How can I post some buffer content including special characters and not have them interpreted as markup?
To include some text in a monospaced font with no formatting, put
``` on a line on its own, then the text, then a
``` line again. You may be familiar with this syntax from Github and other Markdown engines. This syntax is now available on Stack Exchange. Thanks balpha! You can use
~~~ instead of
``` if you prefer.
Here's an example:
This paragraph is <pre>formatted. It uses a `code fence'.
The part of this post between the two horizontal lines above uses the following source syntax:
Here's an example: ``` This paragraph is <pre>formatted. It uses a `code fence'. ```
You can get the same effect by indenting the preformatted block with four spaces.
To typeset Emacs Lisp code, start with
~~~lang-el instead of a plain
~~~. This turns on syntax-based coloring.
(if syntax-indicator (setq coloring t))
can be entered with
```lang-el (if syntax-indicator (setq coloring t)) ```
To get syntax coloring with four-space-indent code blocks, put
<!-- language: lang-el --> in a paragraph of its own immediately before the code block. To get syntax coloring on all the code blocks in an answer, put
<!-- language-all: lang-el --> before the first code block.
If you include a code snippet in some other programming language, you can get syntax coloring with the appropriate
lang-xxx indicator. (Note that on Emacs.SE, because most of the code is Elisp regardless of the tags on a question, the code highlighting is not based on tags.)
