Substituting in strings?

[kotx]

I want to do something like this:

sourcedir := "src"
builddir  := "dist"

args := "--no-source-map {{sourcedir}}:{{builddir}} --style=compressed"

build:
    sass {{args}}

dev:
    sass --watch {{args}}

However the command comes out as sass --no-source-map {{sourcedir}}:{{builddir}} --style=compressed, without the substitutions.

Unfortunately there isn't yet a great way to do this, there's an issue #11, and a pr, which is a little bit stalled, but will probably get picked up and finished eventually: 822.

For now I'd do:

args := "--no-source-map " +  sourcedir + ":" + builddir " --style=compressed"

Which is a little more verbose, but should work.
