I'm currently working on a [node.js][node] module ([node-genx]) with a C++ component.
|
||
|
|
Each time a change was made to the code its necessary to rebuild the
|
||
|
|
module then run the tests. This was getting tiring so I decided to use
|
||
|
|
[guard] to automate the process.
|
||

guard is a ruby gem that provides a DSL for performing actions when
|
||
|
|
a set of watched files change. There a bunch of "guards" available
|
||
|
|
that provide out of the box support for things like [rspec], [jammit],
|
||
|
|
[sass] and [CoffeeScript][coffee-script]. For simple custom cases
|
||
|
|
like mine there is also [guard-shell], which will run a shell
|
||
|
|
command when one of its watched files changes.

guard uses a Guardfile akin to a Makefile in you project directory to
|
||
|
|
configure the guards. Mine looks like this:
|
||
|
|
|
||
|
|
guard 'shell' do
|
||
|
|
watch(%r".*\.(?:cc|h)") { |m| `node-waf build && jasbin` }
|
||
|
|
watch(%r"spec/.*_spec\..*") {|m| `jasbin --verbose` }
|
||
|
|
end
|
||
|
|
|
||
|
|
This runs `node-waf build && jasbin` to rebuild the module and run the
|
||
|
|
tests when any of the C++ source files or headers change. It just runs
|
||
|
|
the the tests when any of the spec files change.
|
||
|
|
|
||
|
|
Once your Guardfile is setup simply run `guard` in you project directory
|
||
|
|
and it will start watching for changes.
