Simple String utilities

README

A collection of string utilities.

These utilities simplifies some formatting needs. The main methods are:

• cut() -> Cuts a String at the required length if bigger or returns the origin otherwise.

• cutAndAlign() -> Cuts a String or pads it right or left with a certain character to the required length if needed

• preserveOnlyChars() -> returns a String containing only the required characters. Optionally the removed characters can be substituted by a placeholder.

• splitInLines() -> split a sentence in lines of the required length based on a given separator.

• capitalize() -> Capitalize the first character of the string and lowercase the others.

• onlyContainsDigits() -> returns true if the string contains only digits.

• onlyContainsAlpha() -> returns true if the string only contains alpha characters (RegExp [a-zA-Z])

• isDartIdentifier() -> returns true if the characters starting at the given position are a valid Dart identifier.

• getDartIdentifier() -> return the valid Dart identifier (if any) at certain position in a source string.

  All these methods are presented also as extensions.
