MessageFormatterDefault

Default formatter for messages of i18n4k

Format must be similar to the Java MessageFormat:

MessageFormat uses patterns of the following form:

MessageFormatPattern:
     String
     MessageFormatPattern FormatElement String

FormatElement:
     { ArgumentIndex }
     { ArgumentIndex , FormatType }
     { ArgumentIndex , FormatType , FormatStyle }

ArgumentIndex: argument with the given index in the parameter list.
               Zero-base (0 is the index of the first argument).
               Use "~" if the index is irrelevant

FormatType: type to format, like number,date, etc. Defined be registered formatter

FormatStyle: Specific style to the FormatType
     StyleModifier
     StyleModifierNames: StyleModifier [ | StyleModifierNames: StyleModifier ] [ | StyleModifier ]

StyleModifier: Free text description of the style.
               Call also contain format pattern. So the patterns can be nested.

StyleModifierNames: Names of the modifier. Can be a list of name separated by slash
     StyleModifierName
     StyleModifierName [ / StyleModifierName ]

StyleModifierName: free text name of the modifier.

Within a String, a pair of single quotes can be used to quote any arbitrary characters except single quotes. For example, pattern string "'{0}'" represents string "{0}", not a FormatElement. A single quote itself must be represented by doubled single quotes '' throughout a String. For example, pattern string "'{''}'" is interpreted as a sequence of '{ (start of quoting and a left curly brace), '' (a single quote), and }' (a right curly brace and end of quoting), not '{' and '}' (quoted left and right curly braces): representing string "{'}", not "{}".

Any unmatched quote is treated as closed at the end of the given pattern. For example, pattern string "'{0}" is treated as pattern "'{0}'".

Any curly braces within an unquoted pattern must be balanced. For example, "ab {0} de" and "ab '}' de" are valid patterns, but "ab {0'}' de", "ab } de" and "''{''" are not.

The FormatType is evaluated by MessageValueFormatter. The MessageValueFormatter defines the possible values of the FormatStyle.

The following MessageValueFormatter are added by default
