Sylvester cannot be used with browserify

[DavidBruant]

Browserify emits en error message:
Error: Cannot find module 'lapack' from '<path>/node_modules/sylvester/lib/node-sylvester'

One way to fix the issue would be to add lapack as dependency of sylvester. In the meantime, I use browserify's --ignore lapack option.

Looks like the suspect portion might be getLapack:

function getLapack() {
    try {
        return require('lapack');
    } catch(e) {}
}

Browserify finds and acts on these requires regardless of surrounding logic, right? (In other words, no conditional requires)

Perhaps this needs to be removed and replaced with dependency injection? I.e.:

require('sylvester')( require('lapack') )
or
require('sylvester')()

That's kind of a major breaking change though. Disclaimer: just a guess on my part. I haven't tried any of this. Is there an alternate approach to dependency injection that wouldn't break plain require('sylvester')?

Possible workaround: substack states that a solution to the halting problem would enable conditional requires. Looks like there's a node module for that 😉

Blarf! I'll stick to --ignore as a workaround for now :-p
