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. /M -- Magnus Therning OpenPGP: 0xAB4DFBA4 email: magnus@therning.org jabber: magnus@therning.org twitter: magthe http://therning.org/magnus
