These diffs are intended for use in copy-editing. The diffs are performed word-by-word, similarly to how the [GNU `wdiff`](http://www.gnu.org/software/wdiff/) tool works. This produces a more meaningful diff for English-language editing.
The diff may be further 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 tool is live at http://dubdiff.com, feel free to use it there.
## Provisioning
You'll need node & npm. Then install dependencies with
npm install
To build and launch a dev server:
npm start
npm run server
To build and launch the distribution server:
npm run build:dist
npm run server:dist
Data is saved to a simple flat file db in the `data` folder. If this folder doesn't exist, create it.
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:
[How To Configure Virtual Memory (Swap File) on a VPS](https://www.digitalocean.com/community/tutorials/how-to-configure-virtual-memory-swap-file-on-a-vps#2)
### Start on boot
To make the application start on boot, run the following:
