RubyMakeScript

Or install it yourself as:

```
$ gem install ruby_make_script
```

Write ruby_make_script like this:

require "ruby_make_script"

make do
    :run .from "a.out" do
        r "./a.out"
    end
    "a.out" .from "test.c" do
        r "gcc test.c"
    end
end

then run:

$ ruby make.rb
$ ruby make.rb run

It works very similar to GNU Make.

Here is a little complex one:

require "ruby_make_script"

def CC(*str)
    r "gcc", "-I.", *str
end

mkdir? ".build"                     # `?` take error as warning, and also return a bool to indicate success/failure.
sources = Dir.glob("**/*.c")        # Dir.glob will be very useful
objects = sources.map{
    |f| ".build/" + f.gsub('.c', '.o')
}
headers = Dir.glob("**/*.h")

make do
    :app .from "prog" do
        runfile $d[0]               # $d: dependencies array
    end
    "prog" .from(*objects) do
        CC "-o", $t[0], *$d         # $t: targets array
    end
    sources.zip(objects).each do |s, o|
        o .from(s, *headers) do
            CC "-c", "-o", $t[0], $d[0]
        end
    end
end
