Intro
-----
A small Vim plugin for previewing markdown files in a browser.
The aim of this plugin is to be light weight with minimal dependencies. Thus, there is *no* polling engine or webserver involved.
Installation
------------
* With [Pathogen](https://github.com/tpope/vim-pathogen): Place `vim-markdown-preview/` in `.vim/bundle/`.
* With [Vundle](https://github.com/VundleVim/Vundle.vim):
* Add `Plugin 'JamshedVesuna/vim-markdown-preview'` to your `.vimrc`.
* Launch `vim` and run `:PluginInstall`
See more [Options](#options).
Usage
-----
By default, when in a `.markdown` or `.md` file, and `Ctrl-p` is pressed, this plugin will either open a preview in your browser, or refresh your current preview (can be remapped, see [Options](#options)).
Your cursor will remain in Vim.
Requirements
------------
### Mac OS X:
* [Markdown](http://daringfireball.net/projects/markdown/) or [grip](https://github.com/joeyespo/grip) (for [GitHub flavoured markdown](#github))
* If using Grip, put `let vim_markdown_preview_github=1` in your `.vimrc` file
* [Safari](https://www.apple.com/safari/)
### Unix:
* [Markdown](http://daringfireball.net/projects/markdown/) or [grip](https://github.com/joeyespo/grip) (for [GitHub flavoured markdown](#github))
* If using Grip, put `let vim_markdown_preview_github=1` in your `.vimrc` file
* [xdotool](https://github.com/jordansissel/xdotool)
* [Google Chrome](https://www.google.com/chrome/browser/) or [other browser](https://github.com/JamshedVesuna/vim-markdown-preview/wiki/Use-other-browser-to-preview-markdown#ubuntu-or-debian)
It is recommended to use grip when rendering Unicode characters.
Options
-------
All options have default values and work out of the box. If you prefer to change these, just add the following lines to your [.vimrc](http://vim.wikia.com/wiki/Open_vimrc_file) file.
Note that after changing an option, you have to restart Vim for the change to take effect.
### The `vim_markdown_preview_toggle` option
This option does two things (to be fixed by [#17](https://github.com/JamshedVesuna/vim-markdown-preview/issues/17)):
1. Display images in the preview
2. Generate preview on buffer write (Example: on `:w`)
There are a total of four values (`0`, `1`, `2`, `3`) this option can take.
Default: `0`, which maps Control p (*not* a buffer write) to generating the preview and does *not* display images.
Example: To display images with the [hotkey](#hotkey) mapping (defaults to Control p).
```vim
let vim_markdown_preview_toggle=1
```
Example: To display images automatically on buffer write.
```vim
let vim_markdown_preview_toggle=2
```
Example: To disregard images and still automatically preview on buffer write.
```vim
let vim_markdown_preview_toggle=3
```
### The `vim_markdown_preview_hotkey` option
By default, this plugin maps `` (Control p) to activate the preview. To remap Control p to a different hotkey, change the binding. Don't forget to add the single quotation marks.
Default: `''`
Example: Mapping Control M.
```vim
let vim_markdown_preview_hotkey=''
```
### The `vim_markdown_preview_browser` option
By default, if you are using Unix, [Google Chrome](https://www.google.com/chrome/) is the default browser. If you are on Mac OS X, [Safari](https://www.apple.com/safari/) is the default.
Note that bug [#16](https://github.com/JamshedVesuna/vim-markdown-preview/issues/16) does not allow cross operating system and browser support. See the [wiki page](https://github.com/JamshedVesuna/vim-markdown-preview/wiki/Use-other-browser-to-preview-markdown) for more help.
Default: `'Google Chrome'`
Example: Using Google Chrome.
```vim
let vim_markdown_preview_browser='Google Chrome'
```
### The `vim_markdown_preview_temp_file` option
By default, this plugin keeps the rendered `.html` file. If you would automatically like to remove the html file after opening it in a browser, set this option to `1`. Note that removing the rendered html file with a slow browser may err.
Default: `0`
Example: Remove the rendered preview.
```vim
let vim_markdown_preview_temp_file=1
```
### The `vim_markdown_preview_github` option
If you prefer [GitHub flavoured markdown](https://help.github.com/articles/github-flavored-markdown/) you need to install [Python grip](https://github.com/joeyespo/grip). Note that this makes a request to [GitHub's API](https://developer.github.com/v3/markdown/) (causing latencies) and may require [authentication](https://github.com/joeyespo/grip#access). This option also requires a network connection.
Default: `0`
Example: Use GitHub flavoured markdown.
```vim
let vim_markdown_preview_github=1
```
### The `vim_markdown_preview_perl` option
If you prefer to use John Gruber's [Markdown.pl](https://daringfireball.net/projects/markdown/) to render HTML, set the following flag:
Default: `0`
Example: Use Markdown.pl to render HTML.
```vim
let vim_markdown_preview_perl=1
```
### The `vim_markdown_preview_pandoc` option
If you prefer to use John MacFarlane's [Pandoc](http://pandoc.org/) to render HTML, set the following flag:
Default: `0`
Example: Use Pandoc to render HTML.
```vim
let vim_markdown_preview_pandoc=1
```
### The `vim_markdown_preview_use_xdg_open` option
If your system does not come with `see`, and you would like to use `xdg-open` to view your rendered html in the browser, set the following flag:
Default: `0`
Example: Use `xdg-open`.
```vim
let vim_markdown_preview_use_xdg_open=1
```
Behind The Scenes
-----------------
1. First, this plugin renders your markdown as html and creates a temporary html file.
* If [image rendering](#toggle) is on, the html file will be in your [working directory](https://en.wikipedia.org/wiki/Working_directory).
* Otherwise, it will be in `/tmp/`.
2. Next, this plugin either opens the html file or refreshes the Google Chrome or Safari tab.
* If you are using GitHub flavoured markdown, `grip` will make a call to the GitHub API and retrieve the html.
3. Lastly, if you choose, this plugin will remove the temporary file.
