Hi All,

I'm following this lecture[1] series and stuck at the module creation section.

Even though I understand the idea of the module I can't figure out the exact syntax to module creation.

Do we have to compile the Haskell file containing the module declaration?

For an example:

Do I have to compile this;

module metricCalc(.....) where ... in a file metricCalc.hs

(First off, I believe module names must start with an uppercase letter, i.e. call it MetricCalc.)

It depends on what you mean more exactly.

You can use `ghci` to load the source file directly:

~~~ Prelude> :l MetricCalc.hs *MetricCalc> ~~~

If you use Cabal you can compile it and place it in a library which you subsequently can install, so that you can use it from other projects you work on.
