Sublime Text3 OmniMarkupPreviewer 404

什么是 Markdown

Markdown 是一种轻量级标记语言，创始人为约翰·格鲁伯（John Gruber）。它允许人们“使用易读易写的纯文本格式编写文档，然后转换成有效的XHTML(或者HTML)文档”。

OmniMarkupPreviewer : 作为 Sublime Text 的一款强大插件，支持将标记语言渲染为 HTML 并在浏览器上实时预览，同时支持导出 HTML 源码文件。

第一次使用时报了如下的错误:

OmniMarkupPreviewer 404

Sorry, the requested URL 'http://127.0.0.1:51004/view/61' caused an error:
'buffer_id(61) is not valid (closed or unsupported file format)'
**NOTE:** If you run multiple instances of Sublime Text, you may want to adjust
the `server_port` option in order to get this plugin work again.

SublimeText console log

SyntaxError: unexpected EOF while parsing

    if isinstance(self.config[key][0], bool):
    KeyError: 'configs'

解决方案

错误原因是默认扩展中的strikeout不能正常加载。

Sublime Text > Preferences > Package Settings > OmniMarkupPreviewer > Settings - User

{
    "renderer_options-MarkdownRenderer": {
        "extensions": ["tables", "fenced_code", "codehilite"]
   }
}

设置保存后就可以正常使用了.

结束语

这虽然是一个小问题，但是由于还不熟悉Python，花了一些时间折腾，OmniMarkupPreviewer+ MarkdownEditing插件的结合，使用Sublime Text3 中进行markdown语法编辑和写作十分的方便,特此记录下来.
