question: why the large diff ? 😰

[jackshirazi]

try viewing with whitespace turned off. Git seems to have got really confused with me editing on the PC (it doesn't normally, and I tried switching to the ubuntu subsystem but it still did this)

This file has Windows (CRLF) line endings now, hence the huge diff. I could push a commit changing it back to Unix (LF) line endings if you like.

I was going to push a commit to fix the line-endings, but was denied :)

If it helps, here is a single-file, no-deps Python script for querying and change the line-endings of files: https://github.com/trentm/eol/blob/master/lib/eol.py

% eol $(git diff --name-only main...)
eol: info: changelogs/head.asciidoc: Unix (LF)
eol: info: packaging.mk: Windows (CRLF)
eol: info: packaging/apm-agent-java-public-key.asc: Unix (LF)

% eol -c unix packaging.mk
eol: info: converted `packaging.mk' to LF EOLs

I ran dos2unix, looks like it worked
