Reducing scroll spam from dzil by:
- Providing ABSTRACTs for all packages.
- Leaving VERSION vertical space where necessary.
Addresses #600 plus other annoyances in the process.
By extension, this also permits negative exponents.
Also breaks a calculator test with a crazy expression where we can't
differentiate between subtrction and negative numbers. Leaving it
broken for now, since the tokenizing is known broken, anyway.
This also required some additional changes to how number_regex is
computed. That was sort of overdue, anyway.
HTML styling is simply display styling plus super-scripted exponents, at
thispoint.
The major change is matching the exponentials more carefully. They only
count if they have <number>E<integer> otherwise they won't work.
Also include a suggested change from @mintsoft to better handle the
spacing of numbers and units in Conversions, by separating them using
our defined regexes.
All-in-all, much more resilient!
Also, minor updates to Conversions to make it work there.
NB: This is clearly not properly factored, yet! This is the first step
to get feedback and improvements from @mintsoft.
- Make number style stuff aware of how to deal with case-insensitive
expoentials.
- Produce consistent output of such strings.
The display format was chosen to be consistent with the output for
Calculator. Also, the parsing is not quite correct as you can't have a
mantissa in the exponent, but this won't catch that.
Should we also do "for_display" on the factors for consistency?
Any and all feedback or improvements are appreciated.
This also breaks the Calculator tests, but I will worry about fixing
those once everything stabilizes.
Considering how all of this works, I'm not sure roles are quite the
right fit. It seems like we might just want a shared "Utility" package
or namespace to let us have access to some common library functions.
DDG::GoodieRole::NumberStyle is a particularly horrible name because
it's not even a role!
Also, the comments suck.
But such is the nature of a proof-of-concept.
