NAME

Text::VisualPrintf - printf family functions to handle Non-ASCII characters

SYNOPSIS

use Text::VisualPrintf;
Text::VisualPrintf::printf FORMAT, LIST
Text::VisualPrintf::sprintf FORMAT, LIST

use Text::VisualPrintf qw(vprintf vsprintf);
vprintf FORMAT, LIST
vsprintf FORMAT, LIST

VERSION

Version 4.03

DESCRIPTION

Text::VisualPrintf is a almost-printf-compatible library with a capability of handling:

- Multi-byte wide characters
- Combining characters
- Backspaces

When the given string is truncated by the maximum precision, space character is padded if the wide character does not fit to the remained space.

FUNCTIONS

printf FORMAT, LIST

sprintf FORMAT, LIST

vprintf FORMAT, LIST

vsprintf FORMAT, LIST

Use just like perl's printf and sprintf functions except that printf does not take FILEHANDLE.

Take a look at an experimental Text::VisualPrintf::IO if you want to work with FILEHANDLE and printf.

VARIABLES

$REORDER

The original printf function has the ability to specify the arguments to be targeted by the position specifier, but by default this module assumes that the arguments will appear in the given order, so you will not get the expected result. If you wish to use it, set the package variable $REORDER to 1.

By doing so, the order in which arguments appear can be changed and the same argument can be processed even if it appears more than once.

IMPLEMENTATION NOTES

Strings in the LIST which contains wide-width character are replaced before formatting, and recovered after the process. Replacement is implemented in the Text::Conceal module.
