Preview - Vim plugin for previewing markup files

by Sergey Potapov (aka Blake)

Intro

Preview plugin is a tool developed to help you to preview markup files such as .markdown, .rdoc, .textile and .html when you are editing them. It builds html files and opens them in your browser.

Supported Formats

The plugin supports the next formats:

• markdown(md, mkd, mkdn, mdown) - depends on

  redcarpet

  ruby gem
• rdoc - depends on

  github-markup

  ruby gem
• textile - depends on

  RedCloth

  ruby gem
• html(htm)
• ronn - depends on

  ronn

  ruby gem
• reStructuredText(rst) - depends on

  RbST

  ruby gem and

  rst2html

  system util

Dependencies

The plugin requires a builtin ruby interpreter. It means that your Vim should be compiled with

--enable-rubyinterp

If output is

1

The second thing you should verify is that you have installed all necessary ruby gems. Please see "Supported Formats" section to find out what gems you need.

For reStructuredText(rst) format except

RbST

rst2html

rst2html

python-docutils

Installation

To install the plugin just copy

autoload

plugin

doc

Usage

• <Leader>P - will open current file converted to HTML in your browser.

I want to remind that <Leader> in most cases is "\" key.

Troubleshooting

If you encountered this err when you press <Leader>P.

Preview: don't know how to handle .modula2 format

You may add this piece of code to .vimrc

autocmd BufNewFile,BufRead \*.{md,mdwn,mkd,mkdn,mark\*} set filetype=markdown

Know bugs

• In some cases vim can do fork if it uses ruby 1.9. To avoid this trouble fork is done via python.

If you found a bug, please report it. Or better send me a pull request:)

TODO

• Make more unique names for temporary files than just base name ending with

  .html

  . There should be

  vim_preview

  prefix, PID of Vim and number of buffer to guarantee avoiding conflicts.
• Add ability to use alternative gems for processing markdown and other formats.
• Handle exception when 'rubygems' is not found.
