APPENDIX: The Visage Language in Depth > String Formatting and Internationaliza...
String Formatting and Internationalization
This section examines two more features of strings: the fine-grained formatting of numerical, date/time, and other types of values using format specifiers and the internationalization and localization of Visage applications.
Using String Format Specifications
Visage supports another, more versatile, form of string expression in which each brace-delimited segment may contain a string format specification and a Visage expression. Listing A-67 shows some examples of this form of string expression.
Listing A-67. Format Specifiers in String Expressions
var b = true;
var i = 1024;
var n = 3.14;
var str = "Hello, World";
println("Display b in a 15 character field [{%15b b}].");
println("Display i in a 15 character field [{%15d i}].");
println("Display n in a 15 character field [{%15f n}].");
println("Display str in a 15 character field [{%15s str}].");
