I'm not taking things like this which solve a given specialist use case
but would need to result in every recipe changing where someone wanted
to do this. To be blunt, your choice of variable name also sucks.
Embrace the power of the scripting we have, there are much more
interesting ways to solve this problem generically. For example, I wrote
this piece of code in a few minutes (admittedly untested):
urlremapper.bbclass:
python () {
mod = False
newsrcuri = []
srcuri = (d.getVar("SRC_URI", True) or "").split()
maps = d.getVarFlags("URLREMAP")
for uri in srcuri:
for u in maps:
if uri.startswith(u):
uri.replace(u, maps[u])
mod = True
newsrcuri.append(uri)
if mod:
d.setVar("SRC_URI", " ".join(newsrcuri))
}
URLREMAP[git://git.yoctoproject.org/linux-yocto-3.4.git] =
"git:///home/nitin/linux-yocto-3.4.git/;protocol=file"
which should do what you want but in a generic way which doesn't require
us to hack each recipe. You can do it completely locally if you create a
classes directory alongside your conf directory and place the .bbclass
there, then add INHERIT += "urlremapper" in local.conf.
Cheers,
Richard
