Markdown Preview

$\subset$: 包含于
Sublime Text 2/3 Markdown Preview
=================================

Preview and build your markdown files quickly in your web browser from sublime text 2/3.

You can use builtin python-markdown parser or use the github markdown API for the conversion.

NOTE: If you choose the GitHub API for conversion (set parser: github in your settings), your code will be sent through https to github for live conversion. You'll have Github flavored markdown, syntax highlighting and EMOJI support for free :heart: :octocat: :gift:. If you make more than 60 calls a day, be sure to set your GitHub API key in the settings :). You can also get most of this in the default Markdown parser with by enabling certain extensions; see "Parsing Github Flavored Markdown"" below for more information.

LINUX users: If you want to use GitHub API for conversion, you'll need to have a custom Python install that includes python-ssl as its not built in the Sublime Text 2 Linux package. see @dusteye comment. If you use a custom window manager, also be sure to set a BROWSER environment variable. see @PPvG comments

Features :

3rd party extensions for the Python Markdown parser:

Extension	Documentation
magiclink	Find and convert HTML links and email address to links (MagicLink Documentation).
delete	Surround inline text with `~~strike through~~` to get del tags ~~strike through~~.
insert	Surround inline text with `^^underlined^^` to get ins tags <ins>underlined</ins>.
tasklist	Github Flavored Markdown tasklists (Tasklist Documentation).
githubemoji	Support for Github Flavored Markdown emojis (GithubEmoji Documentation).
headeranchor	Github Flavored Markdown style header anchors (HeaderAnchor Documentation).
github	A convenience extension to add: `magiclink`, `delete`, `tasklist`, `githubemoji`, `headeranchor`, `superfences`, and `nl2br` to parse and display Markdown in a github-ish way. It is recommed to pair `github` with `extra` and `codehilite` (with language guessing off) to parse close to github's way. Be aware of what extensions `github` loads, because you should not load extensions more than once.
progressbar	Create progress bars (ProgressBar Documentation).
superfences	Allow fenced blocks to be nested under lists, blockquotes, etc. and add special UML diagram blocks (SuperFences Documentation).

Installation :

Using Package Control (Recommended)

For all Sublime Text 2/3 users we recommend install via Package Control.

Install Package Control if you haven't yet.
Use <kbd>cmd</kbd>+<kbd>shift</kbd>+<kbd>P</kbd> then Package Control: Install Package
Look for Markdown Preview and install it.

Manual Install

Click the Preferences > Browse Packages… menu
Browse up a folder and then into the Installed Packages/ folder
Download zip package rename it to Markdown Preview.sublime-package and copy it into the Installed Packages/ directory
Restart Sublime Text

Usage :

To preview :

optionally select some of your markdown for conversion
use <kbd>cmd</kbd>+<kbd>shift</kbd>+<kbd>P</kbd> then Markdown Preview to show the follow commands (you will be prompted to select which parser you prefer):
Markdown Preview: Preview in Browser
Markdown Preview: Export HTML in Sublime Text
Markdown Preview: Copy to Clipboard
Markdown Preview: Open Markdown Cheat sheet
or bind some key in your user key binding, using a line like this one:
{ "keys": ["alt+m"], "command": "markdown_preview", "args": {"target": "browser", "parser":"markdown"} }, for a specific parser and target or { "keys": ["alt+m"], "command": "markdown_preview_select", "args": {"target": "browser"} }, to bring up the quick panel to select enabled parsers for a given target.
once converted a first time, the output HTML will be updated on each file save (with LiveReload plugin)

Enabling Other External Markdown Parsers :

External parser commands and arguments should first be mapped to a name. The path to the binary should be first, followed by flags etc.

    "markdown_binary_map": {
        "multimarkdown": ["/usr/local/bin/multimarkdown"]
    },

Then the name can be placed in enabled_parsers to enable use of the new parser.

    "enabled_parsers": ["markdown", "github", "multimarkdown"],

To build :

Just use <kbd>ctrl</kbd>+<kbd>B</kbd> (Windows/Linux) or <kbd>cmd</kbd>+<kbd>B</kbd> (Mac) to build current file.

To config :

Using Sublime Text menu: Preferences->Package Settings->Markdown Preview

Settings - User is where you change your settings for Markdown Preview.
Settings - Default is a good reference with detailed descriptions for each setting.

Configuring Pygments

If you add the codehilite extension manually in the enabled extensions, you can override some of the default settings.

Turn language guessing on or off (on will highlight fenced blocks even if you don't specify a language) codehilite(guess_lang=False) (True|False).
Show line numbers: codehilite(linenums=True) (True|False).
Change the higlight theme: codehilite(pygments_style=emacs).
Inline the CSS: codehilite(noclasses=True) (True|False).
Use multiple: codehilite(linenums=True, pygments_style-emacs).

See codehilte page for more info.

Meta Data Support

When the meta extension is enabled (https://pythonhosted.org/Markdown/extensions/meta_data.html), the results will be written to the HTML head in the form <meta name="key" content="value1,value2">. title is the one exception, and its content will be written to the title tag in the HTML head.

YAML Frontmatter Support

YAML frontmatter can be stripped out and read when strip_yaml_front_matter is set to true in the settings file. In general the, the fronmatter is handled the same as meta data, but if both exist in a file, the YAML keys will override the meta extension keys. There are a few special keys names that won't be handled as html meta data.

Special YAML Key Names

Yaml frontmatter has a few special key names that are used that will not be handled as meta data:

basepath: An absolute path to configure the relative paths for images etc. (for when the markdown is supposed to reference images in a different location.)
references: Can take a file path or an array of file paths for separate markdown files containing references, footnotes, etc. Can be an absolute path or relative path. Relative paths first use the source file's directory, and if the file cannot be found, it will use the basepath setting.
destination: This is an absolute file path or relative file path for when the markdown is saved to html via the build command or the Save to HTML command. Relative paths first use the source file's directory, and if the file cannot be found, it will use the basepath setting.
settings: This is a dictionary where you can override settings that are in the settings file.

Example

---
    # Builtin values
    references:
        - references.md
        - abbreviations.md
        - footnotes.md

    destination: destination.html

    # Meta Data
    title: Test Page
    author:
        - John Doe
        - Jane Doe

    # Settings overrides
    settings:
        enabled_extensions:
        - extra
        - github
        - toc
        - headerid
        - smarty(smart_quotes=False) # smart quotes interferes with attr_list
        - meta
        - wikilinks
        - admonition
        - codehilite(guess_lang=False,pygments_style=github)

Parsing Github Flavored Markdown :

Github Flavored Mardown (GFM) is a very popular markdown. Markdown Preview can actually handle them in a couple of ways: online and offline.

Online :

Parsing GFM using the online method requires using the Github API as the parser. It may also require setting github_mode to gfm to get things like tasklists to render properly.

Offline :

By default almost all extensions are enabled to help with the github feel, but there are some tweaks needed to get the full experience.

GFM does not auto guess language in fenced blocks, but Markdown Preview does this by default. You can fix this in one of two ways:

Disable auto language guessing in the settings file "guess_language": false,
Or if you are manually defining extensions: "enabled_extensions": ["codehilite(guess_lang=False,pygments_style=github)"]

As mentioned earlier, almost all extensions are enabled by default, but as a reference, the minimum extensions that should be enabled are listed below:

  "enabled_extensions": [
      "extra",
      "github",
      "codehilite(guess_lang=False,pygments_style=github)"
  ]

This may be further enhanced in the future.
