separate or rename dot.Util

[pixelzoom]

JO was considering moving each function in dot.Util to a separate file. Though having them all in one file is a little more convenient when you're going to use multiple functions, only requires one import.

If we don't separate them, then this should be renamed to something like MathUtils. var Util = require("DOT/Util") doesn't really tell me what Util is when I'm reading code.

I don't feel too strongly about it one way or the other. Maybe keep it in a single file (DotUtil or MathUtil) for now and re-evaluate if it starts getting too big?

This issue has been open for 5 months and dot.Util usage is proliferating. Let's make a decision one way or the other.

[jonathanolson]

Due to the number of functions (and that it is growing), I would like these separated out into separate files.

I'm mostly unsure of what the desired packaging / files should be. Do we want DOT/polynomial/solveCubicRootsReal, etc.? Or just DOT/util/solveCubicRootsReal for everything that is in Util right now? Other naming strategies?

[samreid]

First of all, dot.Util isn't too big yet (currently 330 lines, many of which are comments). Second, what about splitting into a few different util files?

NumberUtil:
clamp
moduloBetweenDown
moduloBetweenUp
rangeInclusive
toRadians
toDegrees
cubeRoot

GeometryUtil:
lineLineIntersection
sphereRayIntersection
lineSegmentIntersection
distToSegmentSquared
distToSegment

FunctionUtil:
solveQuadraticRootsReal
solveCubicRootsReal

Not sure where to put linear, and I expect it to be commonly used, perhaps it could be its own file as suggested above?

Also, I'm not opposed to one file per function, but thought this might be a fair medium. Let's discuss.

[pixelzoom]

Too bad we don't have something that strips out unused functions, that would make this a non-issue and maintain the convenience of importing one file.

I'm totally unsure on whether splitting things up a bit like @samreid described would be a good first step, or whether we should just proceed directly to a file-per-function.

[jonathanolson]

I have a preference here for splitting utility functions generally into separate files (so they can be imported with their own name), and I'm willing to put in the work for it.

[pixelzoom]

I'm pretty sure that this will never happen now, due to how painful the refactor would be.

[jonathanolson]

I might try to do one function moved out a week, that probably wouldn't be too bad.

[samreid]

I can't see where in this issue thread it became high priority. Also, the last discussion is nearly a year old. I'm going to demote priority. If @jonathanolson or anyone else wants to self assign or change priority, go for it!
