[gentoo-dev] [PATCH 0/2] Add esed.eclass for sed that dies if caused no changes

[Ionen Wolkens]

Often preferable to use patches so this happens, but sed have its
uses/convenience and this intend to help reduce the amount of old
broken seds causing issues that go unnoticed on bumps.

Inspired by app-portage/iwdevtools' qa-sed (warns on any seds), but
this is for more deterministic use in ebuilds.

Also slightly shortens sed use, -i is default, and no need to || die.
(see @EXAMPLE in eclass for a quick usage overview).

Implementation / available wrappers / usefulness still up for debate,
but without further comments I consider this ready (albeit first time
touching / making an eclass, so I could be overlooking simple things).
Also partly uses >=bash-4.4, so EAPI-7 is not considered.

See github PR[1] for old changelog background.

Up to maintainers but personally would encourage to slowly replace
(almost) all use of sed with either this or patches. Some cases
where it can be inconvenient like eclasses "guessing" that a package
may or may not have something to replace, and that nothing happened
is not an issue.
