This folder contains my patches for various pkgsrc packages.
This README describes how to create and apply them.

= Modifying a package =

	cd /usr/pkgsrc/path-to/package
	make fetch
	cd /usr/pkgsrc/distfiles
	tar xf archived-package.tgz
	cd extracted-package/
	git init

I like tracking my modifications with Git, if only temporarily.

= Generating a patch =

	cd /path-to/extracted-package/
	git diff ... | conv -i

The resulting patch will be placed in ~/patches.

= Applying a patch =

Be sure to set the LOCALPATCHES variable in mk.conf:

	echo LOCALPATCHES = $HOME/patches >> /etc/mk.conf

After that, local patches will be applied automatically, assuming
they are formatted correctly and placed in the correct directory.

= Undoing patches =

I haven't tried it yet, but the following command should work:

	cd /usr/pkgsrc/path-to/package/work/
	find . -name '*.orig' | while read f; do
		mv "$f" "${f%.orig}"
	done

It probably won't work if you've tried to apply patches twice, as
each do-patch theoretically presumably creates new .orig files.

= Rebuilding with new patch =

First, you may want to undo the old patches as described above.

	make do-patch
	make do-build

The first step will complain if patches have already been applied
(and not undone), but your new patch should be applied regardless.
