quds_formula_parser 0.1.0

quds_formula_parser: ^0.1.0 copied to clipboard

• Performance Optimizations (2x faster parsing, 1.5x faster evaluation):
  • HashMap-based function lookup: O(n*m) → O(1) for function identification (+50% on function-heavy formulas)
  • Index-based string parsing: Eliminated redundant substring operations (+20-25% parsing speedup)
  • Pre-allocated evaluation stacks: Reduced memory reallocation during evaluation (+5-10% on large formulas)
  • Bracket pair caching: Pre-computed during organization phase (+10% on nested expressions)
• Added comprehensive performance benchmarks in test/performance_test.dart
• All optimizations maintain 100% backward compatibility and correctness

• Initial version.

• Updated the packege to fit the pub scores creteria.

• Updated the packege to fit the pub scores creteria.

• Added support of fraction type.
• Simplified the usage of the provider
• Simplified the registration of new function

  provider.registerFunction(
      notations: ['Randomize', 'Custom.Rnd'],
      evaluator: (params) {
        return params.first * Random().nextInt(100);
      },
      checkParameters: (params) => params.length == 1 && params.first is num);

• Added manipulating method

  provider.registerFunction(
      notations: ['SinX'],
      checkParameters: (params) => params.length == 1 && params.first is num,
      evaluator: (params) {
        return sin(params.first);
      },
      manipulateResult: (r) =>
          r.abs() < 1e-6 ? 0.0 : r);

• Created an extension on Iterable<T> to perform quick queries on iterables like isSingle, isCouple, isTriple, second, third, fourth, fifth.

• Support new functions:

• Mathematical: Random, ASin, ACos, ATan, ATan2, Root, RandomInt, RandomDouble, GCD, LCM, IsPrime.
• Statisticals: Permutations, Combinations, Mode.
• Geometry: IsPoint, IsPoint2D, IsPoint3D.
• Core: IsDate, IsTime, IsDateTime, IsDuration, IsBool, IsFraction, IsAtom.
• Date & Time: Hour, Minute, Second.
• Logical: XOR, Toggle, AllTrue, AnyTrue, AllFalse, AnyFalse, RandomBool.
• Iterables: List, Reverse, Set, Intersect, Union, Differnce.

• Support new constants:

• Mathematical: ln10, ln2, log2e, log10e, sqrt1_2, sqrt2.

• Support new types:

• Iterables with IterableWrapper as its values wrapper.

• Simplified some functions registrations.

• Simplified the bodies of most of operators.
• Defined new functions:MemberAt, IndexOf.
• Developed the 2d plotter example.

• New Feature: Simplification of the formula.
• New Feature: [Beta] Convert the formula to Tex-Notation to be visualized.

• Enhanced the performance

• Updated the README.md file

• Developed a comprehensive example showing the power of the package

• Fixed the screenshots of the package
