Method sprintf()
- Method sprintf
string sprintf(string format, mixed ... args)
- Description
Print formated output to string.
The format string is a string containing a description of how to output the data in args. This string should generally speaking have one %<modifiers><operator> format specifier (examples: %s, %0d, %-=20s) for each of the arguments.
The following modifiers are supported:
'0' Zero pad numbers (implies right justification).
'!' Toggle truncation.
' ' Pad positive integers with a space.
'+' Pad positive integers with a plus sign.
'-' Left adjust within field size (default is right).
'|' Centered within field size.
'=' Column mode if strings are greater than field size.
'/' Rough line break (break at exactly field size instead of between words).
'#' Table mode, print a list of '\n' separated word (top-to-bottom order).
'$' Inverse table mode (left-to-right order).
'n' (Where n is a number or *) field size specifier.
'.n' Precision specifier.
':n' Field size precision specifier.
';n' Column width specifier.
'*' If n is a * then next argument is used for precision/field size.
"'" Set a pad string. ' cannot be a part of the pad string (yet).
'~' Get pad string from argument list.
'<' Use same argument again.
'^' Repeat this on every line produced.
'@@' Repeat this format for each element in the argument array.
'>' Put the string at the bottom end of column instead of top.
'_' Set width to the length of data.
'[n]' Select argument number n. Use * to use the next argument as selector.
The following operators are supported:
'%' Percent.
'b' Signed binary integer.
'd' Signed decimal integer.
'u' Unsigned decimal integer.
'o' Signed octal integer.
'x' Lowercase signed hexadecimal integer.
'X' Uppercase signed hexadecimal integer.
'c' Character. If a fieldsize has been specified this will output the low-order bytes of the integer in network byte order.
'f' Float.
'g' Heuristically chosen representation of float.
'G' Like %g, but uses uppercase E for exponent.
'e' Exponential notation float.
'E' Like %e, but uses uppercase E for exponent.
'F' Binary IEEE representation of float (%4F gives single precision, %8F gives double precision.)
's' String.
'O' Any value (debug style).
'n' No operation (ignore the argument).
't' Type of the argument.
'{' Perform the enclosed format for every element of the argument array.
'}' Most modifiers and operators are combinable in any fashion, but some combinations may render strange results.
If an argument is an object that implements lfun::_sprintf, that callback will be called with the operator as the first argument, and the current modifiers as the second. The callback is expected to return a string.
