Module ListBuilder

A module for building CSV-like strings, or types that extend string, from a custom separator and/or custom types.

Each module provides predicates of2(...) to of8(...) for creating a list of up to 8 items, which take either a string or a custom type as input to be converted to a string. The result will either be a string, or a custom type that extends string.

The following modules are provided:

ListBuilder<separator>: Predicates to build a string from a list of string-valued arguments separated by a custom separator.
ListBuilderOf<separator, T, toString>: Predicates to build a string from a list of arguments of a custom type T, converted to strings via the toString predicate, using a custom separator.
TypedListBuilder<separator, S>: Predicates to build a string from a list of string-valued arguments separated by a custom separator, where the result is a custom type S that extends string.
TypedListBuilderOf<separator, S, T, toString>: Predicates to build a string from a list of arguments of a custom type T, converted to strings via the toString predicate, using a custom separator, where the result is a custom type S that extends string.

A recommended use of this module is by using the predicates defined in the qtil.strings.Chars module, which defines predicates such as Char::comma/0, Char::colon/0, Char::at/0, etc.

Imports

Char	A module that provides a `Char` class — a subtype of `int` representing a single character code, with utilities such as `toUppercase()`, `isDigit()`, and `repeat(n)`.
Join	A module for joining strings with a separator, for example, `join(":", "a", "b") = "a:b"`.
SignaturePredicates	A module for creating signature predicates without requiring separate declarations.
