Automates ImageOptim, ImageAlpha, and JPEGmini for Mac to make batch optimisation of images part of your automated build process.
$ npm install -g imageoptim-cli
ImageOptim-CLI is written in Shell and AppleScript, so you don't need Node.js or npm. You can install manually by downloading the latest zip then adding ImageOptim-CLI to your $PATH.
$ curl --output imageoptim-cli.zip https://codeload.github.com/JamieMason/ImageOptim-CLI/zip/1.7.10
$ unzip imageoptim-cli.zip
$ export PATH=$PATH:imageoptim-cli/bin
See how ImageOptim performs compared to other image optimisation tools.
The ImageOptim-CLI Grunt plugin is grunt-imageoptim.
There's a short video demo to give you an idea of how it works.
This command will optimise all image files in your Awesome project.
imageOptim --directory ~/Sites/Awesome # [options]
This command will optimise just the .jpg files in your Awesome project.
find ~/Sites/Awesome -name '*.jpg' | imageOptim # [options]
The long format for enabling options is as follows;
imageOptim --jpeg-mini --image-alpha --quit --directory path/to/images
The equivalent of the above in short format is as follows;
imageOptim -j -a -q -d path/to/images
Adding the below to your_project/.git/hooks/pre-commit will run ImageOptim-CLI each time you commit new and changed files into your project. Any files which aren't images will be ignored.
git diff --cached --name-only --diff-filter=ACM | imageOptim # [options]
