dubdiff
A diff viewer for markdown-formatted and plaintext documents.
These diffs are intended for use in copy-editing. The diffs are performed word-by-word, similarly to how the GNU 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 markdown-sensitive processing of the wdiff comparison is at ..., for the curious.
Version 2
This is a complete rewrite of Dubdiff with:
- simpler project architecture
- client-side diffing engine and simplified server
- server-side rendering
- switch to React from Angular
- clean up of diffing engine
- goal of implementing a HTML diff viewer
Basically I'm rewriting it for fun.
Live Server
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 production server:
npm run build:prod
npm run server:prod
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:
