skdiff

Command to generate visual differences between two sketch files. Useful as a git diff for your Sketch files.

This is a bash script that will run in your macOS using Terminal app.

Usage

skdiff -h for help information

What changed since the last commit of this Sketch file?

skdiff example_1.sketch will check if this file is tracked by git and, if it is, will provide a summary of what artboards have been added, deleted or changed.

<> S1_10.png has changed
-- S1_End.png removed
<> S1___Overview@2x.png has changed
++ S2___Overview@2x.png added

A directory called changes is written to the current directory that contains all the artboards listed in this summary.

Artboards that have changed are represented by a composite image of the before, after and overlayed before and after artboards using red coloring to highlight the specific changes.

Using the functionality of skdiff as part of another script

skdiff is written so the internal functions can be called from your own bash script. Just source the skdiff script and you'll have access to its variables and functions.

Installation

Run the following command to download and install

curl https://raw.githubusercontent.com/ali5ter/sketchDiff/master/skdiff -o skdiff && chmod 755 skdiff && mv skdiff /usr/local/bin/

skdiff will check the following prerequisites:

1. You're running skdiff on macOS

2. You have Sketch installed

3. You have NPM installed

4. You have blink-diff installed. If you're familiar with npm, you could install this manually using

    npm install -g blink-diff
   

The blink-diff utility is used to generate the composite of two images. skdiff will attempt to install this utility if npm is present but the utility is not.
