6 It's an ugly workaround, and one that i'd like to remove if possible.
7 Right now that's a fairly big 'if', but one possible way to do it
8 suggests itself:
10 - Modify the sed ebuild to install a gsed -> sed symlink on GNU systems.
11 - Fix sed usages in the tree where that's practical / easy (such as -i /
12 -e argument ordering). Otherwise, explicitly call gsed if we need GNU
13 extensions that aren't present in BSD / others.
14 - Remove the alias in non-gnu systems' profile.bashrcs.
16 As ciaranm said earlier, GNU sed does have a lot of useful extensions;
17 however BSD sed (for example) supports most of them, and I can't help
18 but feel it'd be nice to be able to use a platform's native sed wherever
19 possible. The above scheme is just what seems like the obvious solution
20 that shouldn't affect GNU systems too much, but lets us use native apps
21 where possible. Where those native apps suck too much then those
22 profiles can just keep the gsed alias.
24 At the moment, this is just a random thought that occurred and got
25 written down, so don't be surprised if I've overlooked something.
27 Any comments? Suggestions, flames? (Except from ciaranm, of course...)
