dubdiff
A diff viewer for markdown-formatted documents.
Uses the wdiff tool as a diffing engine. This produces an output that is more useful for copy-editing tasks. This wdiff comparison is then processed in a way that is aware of markdown formatting. The resulting output attempts to show differences of copy within the final document format (rather than differences of format).
The markdown-sensitive processing of the wdiff comparison is at server/components/wdiff/index.js, for the curious.
Live Version
The tool is live at http://dubdiff.com, feel free to use it there.
Provisioning
You'll need the following:
- node & npm
- grunt and bower (
npm install -g grunt bower) - ruby (
apt install ruby) - sass (
gem install sass) - wdiff (
apt install wdiff)
The wdiff binary should be placed in the bin subfolder, or a link should be made to the binary. Eg. ln -s /usr/bin/wdiff bin/wdiff.
npm install && bower install
mkdir data
Low-memory environments
On a low-memory machine, eg. a DigitalOcean 512MB instance, you will need to enable virtual memory. Use this guide:
