I have a rakefile which takes a C++ source tree, and creates objects
elsewhere.
i.e., source/dir/file.cpp compiles to build/dir/file.o. I created a
rule for this, and all works well.
Often it is handy to compile a single file based on just the source
path, without wanting to resolve what the object file will be. (i.e,
from Vim, calling 'rake expand("%")' ).
So I created a task like this:
task :singleobj do |t|
src = ENV['srcfile']
obj = src.pathmap( "%{^source,build}.o" )
sh( "rake #{obj}" )
end
This allows me to issue the command from Vim
'rake singleobj srcfile=source/dir/file.cpp'
This is good, but the rake command is called twice. Is there a way I
can avoid calling rake recursively?
Thanks,
~S
