If you open a GITHub commit, click on the 'changed file' link and click on any one of the changed files, the commit url in the browser will append a diff hash id like this:
'#diff-3db08c3ce067ae92af324b2d8bd6b5e2'.
Can anybody please explain me what exactly is this diff hash id, is there any git command to generate this id for a changed file?
I have by coincidence asked support, and github aswered me that this is non documented. We should instead use some sort of API to recover the URI.
I don't like the answer but it is what it is.
The 32 characters following "diff-" is an MD5 hash of the path and filename. Here's an example using node.js:
const crypto = require('crypto');
var hash = crypto.createHash('md5').update(path+'/'+filename).digest('hex');
