Jaskell Java8 is Java8 Edition of Jaskell Core library. It rewritten completed by Java 8. So easy to use in Java8 projects.

It includes a parsec combinators library , a SQL expressions library and a arithmetic expressions parser.

• SQL add sum function
• make sum and count functions as literal, so them could have alias
• add parsec common namespace for common jobs
• make parsec combinators easier to use
• make group/order by accept name list
• add choice(list of parsecs) function
• make name could escape
• make parameters of sql more clean

1.2 着重 SQL 组件重构

• add text state constructor
• add int tests
• bugs in int parser fixed
• all SQL statements generate upper case words

• add expression parser library
• bugs fixed

• parsec can parse a Seq or String once by shortcut method
• add scientific number parser
• add a test include scientific number new test
• bug fixed

• where could order and group

• add parameter expression

• make sql components easier to used.
• add distinct
• add select list
• add select function
• add order by and group by list
• add in predicate
• bug fixed, Select.From now is CouldFrom

• add more default methods sugar for parsec functions
• make binary public

• having now is a query

• add could having

• add weak expression sample mix boolean and arithmetic expression

• add could order, limit offset for having

• add could union for query
• add could returning

• add predicate parser

• formal sync as jaskell-dotty

• try now named attempt
• create a try type like scala try

• reflections of Try

• add map and recover for try

• add simple failure for try

• auto attempt in option
• add attempt method in parsec

• improve Try type

• code clean in Try

• use junit 5
• add croupier type for custom random select algo

• add lite scaled algo for croupier
• add binary scaled
• add binary rank

• fixed edge condition mistake in damping
• make invert smoothness. now it just be a negative damping

• add enumerate parser
• add enumerate utils methods in object Txt and Combinator

• add join map/flat map from 1 to 8 for Try type

• add tryIt methods for function types
• make Try Class final
• function types could throw when apply call

  • tail method
  • last method
  • butLast method
  • add static methods for tuple construct
  • size method
  • get by pos method
  • toList method
  • toMap method

• add methods for triable interface make it as lazy try
  • joinMap
  • joinFlatMap
  • map
  • flatMap accept argument typed Function<T, Try<U>>
  • async methods
• triable collect method return try object

• rename tryIt of Functions to collect
• add stream method for try

• add try tests
• upgrade project settings
