逐块更改文件类型(或其他Vim设置)? [英] Change filetype (or other Vim settings) blockwise in a file?

问题描述

我在Vim中编写了很多Perl.通常，我只是一起整理一些CGI脚本，然后将CSS放入程序代码中.因此，最近我问自己是否可以在代码中围绕这些块添加一些特定于Vim的注释，以便vim可以将特定区域突出显示为不是层叠的样式表，而不是Perl脚本.

I program a lot of Perl in Vim. Often I just hack together some CGI script and put the CSS right into the program code. So lately I asked myself if it was possible, to put some Vim-specific comments around such blocks in my code, so that vim highlights the specific area not as a Perl script, but as a cascading stylesheet.

与Mojolicious一起使用时，这也很整洁，您可以将整个模板仅嵌入到DATA区域中，但随后会丢失所有HTML高亮显示.

This also would be neat when working with Mojolicious where you can embed entire templates just into the DATA-area but lose all the highlighting of the HTML then.

当然，我可以在文件类型/突出显示之间手动切换.但我想知道是否有更好的方法.

Of course, I could switch manually between the filetypes/highlighting. But I wonder if there is better way.

谢谢， 斯文

推荐答案

您可以为单个文件设置多种文件类型:

You can have multiple filetypes set for a single file :

:set ft=perl.css

这样一来，您将获得两种语言的全功能(如果有的话，还提供摘录)和半正确的高亮显示:如果将CSS规则放在引号中，它将被高亮显示为字符串.

With that you get omnicompletion (and snippets if applicable) for both languages and semi-correct highlighting: if you put your CSS rules in quotes it will be highlighted as a string.

(昨天)我刚刚发现了一个受Emacs功能启发的酷插件，名为 NrrwRgn .它允许您选择代码的区域"，例如说说Perl文件的CSS部分，然后在您为:set ft=css的临时窗口中对其进行编辑.每次保存都会反映在原始窗口中.在处理包含PHP/HTML/JS/CSS的PHP模板时非常有用.

I've just found (yesterday) a cool plugin inspired by an Emacs feature called NrrwRgn. It allows you to select a "region" of code, say the CSS part of your Perl file and edit it in a scratch window for which you :set ft=css. Each save is reflected in the original window. Very useful when dealing with PHP templates full of PHP/HTML/JS/CSS.
