LaunchMenu-calculator applet

A simple calculator in LaunchMenu. This applet is still a work in progress. Current functionality uses custom interpreter to parse and evaluate mathematical expressions. Feature list can be found on the megathread.

TODO

  • Modulo operator
  • Seperated semantics
    • Bracket imbalance error suggestions
  • Copy action to copy result to clipboard (cmd+c/ctrl+c)
  • Search pattern?
    • Consider /^=/ like excel formula
    • Consider a fast way to test if a query looks like a calculate-able query to prevent excessive parser runs (and slowdowns respective to that). Though maybe parser is fast enough? We believe parser to be fast enough
  • Implement ANS and M+ (save as variable)
    • Consider adding variable support
  • Conversions from one unit to another (5kg to lb, 500m in miles)
    • Unit tracking would be great

Maybe a separate math applet?

  • Plotting?
  • Integrals and Derivatives?

Error suggestions:

Query: "123+224+423+3124)/4"
Suggestions: [
  "(123+224+423+3124)/4", //tokenAddition
  "123+(224+423+3124)/4", //tokenAddition
  "123+224+(423+3124)/4", //tokenAddition
  "123+224+423+(3124)/4", //tokenAddition
  "123+224+423+3124/4"   //tokenRemoval
]

Default action of these suggestions should replace search field with the calculation suggested
