## Installation

You can install MarkdownEditing either from Package Control (recommended) or manually. Package Control automatically download the package and keeps it up-to-date. Manual installation is required if you need to tweak the code.

If you are using Sublime Text 2, you have to disable the native package _manually_. To do that, add `Markdown` to your `ignored_packages` list in ST user settings:

"ignored_packages": [..., "Markdown"],

> Getting "Error loading syntax file..."? See [this](#error-loading-syntax-file).

### Package Control

The preferred method of installation is via [Sublime Package Control][PackageControl].

1. [Install Sublime Package Control][InstallPackageControl]

2. From inside Sublime Text, open Package Control's Command Pallet: <kbd>CTRL</kbd> <kbd>SHIFT</kbd> <kbd>P</kbd> (Windows, Linux) or <kbd>CMD</kbd> <kbd>SHIFT</kbd> <kbd>P</kbd> on Mac.

3. Type `install package` and hit Return. A list of available packages will be displayed.

4. Type `MarkdownEditing` and hit Return. The package will be downloaded to the appropriate directory.

5. Restart Sublime Text to complete installation. Open a Markdown file and this custom theme. The features listed below should now be available.

### Manual Installation

1. In Sublime Text, open the menu "Preferences" -> "Browse Packages...". This is the Sublime Text Packages directory.

2. [Download and unzip](https://github.com/SublimeText-Markdown/MarkdownEditing/archive/master.zip) or [clone](https://help.github.com/articles/cloning-a-repository/) this repository to a directory `MarkdownEditing` in the Sublime Text Packages directory.

3. The folder structure should look like `.../Sublime Text 3/Packages/MarkdownEditing/[files]`.

4. Restart Sublime Text to complete installation. Open a Markdown file. The features listed below should now be available.

## Features

You can access most features through Command Palette. You can launch it from `Tools -> Command Palette...`. MarkdownEditing commands start with `MarkdownEditing:`. And they are only visible when a markdown file is open and active.

### Markdown features

* __Pairing__

- Asterisks and underscores are autopaired and will wrap selected text.

- If you start an empty pair and hit backspace, both elements are deleted.

- If you start an empty pair and hit space, the right element is deleted.

- Backticks are paired. So entering `` ` `` will expand to `` `(cursor here)` ``.

* __List__

- At the end of a list item, pressing <kbd>Enter</kbd> will automatically insert the new list item bullet.

- Pressing <kbd>Tab</kbd> on the blank list item will indent it and switch the list bullet to another one (Order is `*`, `-`, `+` in a cycle).

- Pressing <kbd>Shift</kbd> <kbd>Tab</kbd> on the blank list item will unindent it in the same way as above.

- Sequential <kbd>Tab</kbd> s or <kbd>Shift</kbd> <kbd>Tab</kbd> s are supported.

- You can disable automatic bullet switching or choose which bullets to be used, in your settings file (`mde.list_indent_bullets`).

- If a list item contains a [GFM task][], pressing <kbd>Enter</kbd> at the end of the line will continue with a new blank task.

* __Blockquote__

- At the end of a blockquote line, pressing <kbd>Enter</kbd> will automatically extend blockquote.

- Selecting some text and pressing <kbd>></kbd> will convert it to blockquote. The first and the last line don't have to be fully selected; partial select works, too.

* __Link__

- Left bracket pairing is modified to eliminate the selection and leave the cursor at a point where you can insert a `[]` or `()` pair for a link.

- If you leave the cursor on a link, you can right click and jump between reference and url.

* __Navigation__

- Displays Markdown headers in the Project Symbol List (`Goto -> Goto Symbol in Project...`). They will start with `#`, so you will know they belong to markdown files at a glance. Also they will be on top of the list because of the precedence of `#`.

- Headers also appear in Document Symbol List (`Goto -> Goto Symbol...`)

- You can fold current section with <kbd>Ctrl</kbd> <kbd>Tab</kbd>

- You can navigate between adjacent headers with `Find Next(Previous) Heading` command.

* __Strikethrough__

- <kbd>~</kbd> wraps selected text with `~~` (strikethrough). When you for instance select the word "foo" and hit `~`, the result will be `~~foo~~`.

* __Header__

- Typing `#` when there's a selection will surround it with `#` to make it a headline. Multiple presses add additional hashes, increasing the level of the header. Once you hit 6 hashes, it will reset to 0 on the next press. The `mde.match_header_hashes` will determine if the `#` are mirrored on both sides or just at the beginning of the line.

- Typing return at the end of a line that begins with hashmarks will insert closing hashmarks on the headline. They're not required for Markdown, it's just aesthetics, and you can change the `mde.match_header_hashes` option in your settings to enable (disabled by default).

- Setext-style headers can be completed with `Tab`. That is, typing `Tab` on a line containing only `=` or `-` characters will add or remove enough characters to it to match the length of the line above.

- New documents will be named automatically based on the first header.

### Wiki features

Wiki links are defined by surrounding a (wiki) word with double square brackets, for example:

[[SampleWikiPage]]

The user can `open` wiki page using a sublime command. This will search the current open file's directory (and sub-directories) for a file with a matching name and a markdown extension. For example, opening the previous wiki link

will look for and open a file named:

SampleWikiPage.md

Note that, if the wiki page does *not* yet exist, if will be created with a header matching the page name. However the file will only actually be created on the file system, when it is saved by the user.

The user can `list back links` and of course to open them. Back links are pages that reference the current page. This allows pages to be tied together into a personal wiki. A common technique is to define *tag* wiki pages and to list any tags for a page as references to the tag pages at the bottom of the page, for example:

[[TagSyntax]] [[TagDev]] [[TagPython]]

This allows the user to list all pages with a specific tag, by opening the tag page and list all back links.

Journal wiki pages are also supported. A journal page is just a wiki page with a name matching the current date.

Lastly the command to open the *home* page is provided, where the home page is just a wiki page named `HomePage`.

## Configuration

The plugin contains 3 different Markdown flavors: Standard Markdown, GitHub flavored Markdown, MultiMarkdown. Default is GitHub flavored Markdown. If you want to set another one as default, open a Markdown file and select your flavor from the menu: `View > Syntax > Open all with current extension as`. You're done.

You may want to have a look at the default settings files. They are located at:

Packages/MarkdownEditing/Markdown.sublime-settings [GitHub flavored Markdown]

Packages/MarkdownEditing/Markdown (Standard).sublime-settings

Packages/MarkdownEditing/MultiMarkdown.sublime-settings

If you want to override any of the default settings, you can open the appropriate user settings file using the `Preferences > Package Settings > Markdown Editing` menu. Each flavor has a different settings file.

Bold and italic markers are configurable through ST shell variables. You can use `Preferences > Package Settings > Markdown Editing` menu to see the default settings file. In order to override it, copy & paste its content into the user settings file (`Packages/User/Bold and Italic Markers.tmPreferences`) from the menu and make your edits. It is pretty straightforward.

In order to activate the dark or the yellow theme, put one of these lines to your user settings file of the flavor (`Packages/User/[flavor].sublime-settings`):

"color_scheme": "Packages/MarkdownEditing/MarkdownEditor-Dark.tmTheme",

"color_scheme": "Packages/MarkdownEditing/MarkdownEditor-Yellow.tmTheme",

"color_scheme": "Packages/MarkdownEditing/MarkdownEditor-ArcDark.tmTheme",

If you want to go with your already existing theme, you can reenable it with the same method as above. Keep in mind that, that theme may not cover all the parts of the Markdown syntax that this plugin defines.

### Additional color themes:

- [Blackboard theme][linkBlackboardTheme] by [@mdesantis][mdesantis]

- [monokaiC](https://github.com/avivace/monokaiC) by [@avivace][avivace]

By default, when you install the plugin, files with these extensions will be assigned to Markdown syntax: "md", "txt", "mdown", "markdown", "markdn". If you want to prevent any of these extensions to be opened as Markdown, follow these steps:

1. Click on the language menu at bottom right

2. Select "Open all with current extension as"

3. Choose your preferred syntax for that extension

## Tips

We are maintaining a [tips section][tips] in our [Wiki][]. Jump there to learn from others or share your experiences with others.

## Enable WYSIWYG

Sublime can be configured into a WYSIWYG (what you see is what you get) editor with two other plugins:

1. Markdown Preview (https://packagecontrol.io/packages/Markdown%20Preview)

1. Livereload (https://packagecontrol.io/packages/LiveReload)

Install them if you haven't. Then

1. Open Palette

1. LiveReload: Enable/Disable Plugins

1. Enable Simple Reload.

Now open palette and choose "Preview in Browser" and you will get a WYSIWYG editor.

## Troubleshooting

### Error loading syntax file...

__Are you getting this error after installation: _**Error loading syntax file** "Packages/Markdown/Markdown.tmLanguage": Unable to open Packages/Markdown/Markdown.tmLanguage_?__

> This is caused by open markdown files at the install time. You have to __manually change their syntax to your newly installed Markdown syntax__. Read the below paragraph for more details on this.

_Note_: Sublime text has a native tiny package for Markdown. However, when MarkdownEditing is enabled, native package causes some conflicts. For this reason, MarkdownEditing will automatically disable it. Since it doesn't bring anything new over MarkdownEditing, this is not a loss. But remember, when you disable MarkdownEditing, you have to reenable the native one manually (if you want).

### Roll back to an older version

When you notice any undesired behavior introduced by the latest update, your feedback is always welcome in our [issue page](https://github.com/SublimeText-Markdown/MarkdownEditing/issues). However before it's fixed, you can rollback to [an earlier version](https://github.com/SublimeText-Markdown/MarkdownEditing/releases). Find the desired version and download the zip file, then follow [manual installation guide](#manual-installation)

## Related Plugins

* [Knockdown][]

Knockdown offers useful Markdown features and a custom Markdown theme. All of its unique features except its theme are ported to MarkdownEditing and some of them are actually improved further in MarkdownEditing.

* [Sublime Markdown Extended][]

* [SmartMarkdown][]

* [MarkdownTOC][]

- Sublime Text 3 plugin for generating a Table of Contents (TOC) in a Markdown document.

* See https://packagecontrol.io/search/markdown for more.

## Known Bugs

* Setext-style headers (`===` and `---`) do not show up in the symbol list. This is due to a Sublime Text limitation (see [#158][]). However, we are able to put a placeholder to indicate the existence of the header. We encourage you to use Atx-style headers (`#`).

* Installing for the first time while having markdown files opened may cause MarkdownEditing to behave unexpectedly on those files. Close and reopen those files to fix it.
