Static Resources in Salesforce are often zip files containing multiple files.
If you're keeping static resource under version control using git, here's how
to get useful diffs for them whether they are zip files or single text files.
Create a shell script which will identify whether a file is a zip file or not.
If so, it should unzip the contents to stdout; otherwise, it should just output
the contents of the file. I called it resource-conv.
#!/bin/bash
file -b --mime-type $1 | grep application/zip && unzip -c -a $1 || cat $1
Tell git to use this conversion utility for a new "resource" diff driver:
$ git config [--global] diff.resource.textconv resource-conv
Tell your repo that .resource files should use the "resource" diff driver by
adding the following to your .gitattributes:
*.resource diff=resource
