This all reminds me that I so much disliked the idea of creating a .c
file by running sed against virsh.c and then #include'ing that .c file
into virsh.c that I instead made a separate function for
cmdInterfaceEdit rather than adding to it. I had thought that someone
refactored that long ago so that the main bit of code was a helper
function called by all (thus removing the sed trickery), but apparently
we only talked about it. (*adds a line to todo list*)
Heh, thanks for pointing that out. I've completely forgotten about
iface-edit. So my patch is incomplete. :(
On the other hand, seems like sed script is doing its work well. I've
taken look at generated code and it was good. Even when I've introduced
this dom_edited variable, it was renamed to network_edited and
pool_edited respectively in those generated functions. So honestly,
unless we are doing some different magic in cmdInterfaceEdit (quick look
doesn't say so) I think we can believe the sed script and make
cmdInterfaceEdit being generated as well. The advantage is - if somebody
(this time it's me) introduce any feature, fix a bug, all other *-edit
commands benefit from it immediately.
