Swift Utility

Useful stuff. BSD. Use at your own risk.

A lot of these are "notes" and have not been tested

Cartesian Product

• What it says on the label

CharacterSet

• Don't know if I'll keep this long term, but character set members

Collection

• Useful stuff, not fully updated to Swift 4 See "TODO"s

Core Error

• Basic utility error
• Contextualizing
• ContextError
• Common Error Handler type
• attempt (replaces try? and try!) and Boolean variation testAttempt

Diagnosis

• Postfix printing
  • Also debug-only version, which requires compilation flags
  • Also dump-enabled high octane versions
• Diagnostic printing
  • here: The current file and line number
  • diagnose(object): shows the object in detail with pass-through
• Infix printing
  • offers low-precedence forward-looking print or dump functionality

Dispatch

• General timing and invocation utilities

Math

• Exponentiation
• Double unification

Nostalgia

• Prefix, Postfix increment/decrement

Optional

• Controlled landings for forced unwraps
• do instead of optional.map(action)
• Conditional map/flatmap application
• Zipping optionals / flatmap2 for optionals

Optional Comparison

• What it says on the box. Follows IEEE754 wrt NaN

Precedence

• Custom items including very low and very high

Reflection

• Self-reflecting reference types

Splatting

• 2-, 3-, 4- item

TimeTest

• Avoid using in playgrounds

Unimplemented

• Clean line/source info

With

• Flexible initialization and immutable assignment

Moved from Sources

Most operators have been moved out of the main sources into Various

• Casting
  • Force cast to the type demanded by static context (Groffcast)
  • Unsafe bitcast constrained to equal memory footprint (Ashcast)
  • Dynamic type dispatch (Dynogroff)
  • Dynamic casting without bridging (Groffchoo)
• Assignment
  • In-place value assignment (EridiusAssignment)
  • Conditional in-place assignment (Ashignment)
• Failable and direct chaining (ChainChainChainOfFools operator)
• Interesting things that caught my eye
• Notes on stuff that I'm looking at at the moment
