DESCRIPTION

This is a collection of utilities using Text::ANSI::Fold module. All functions are aware of ANSI terminal sequence.

FUNCTION

There are exportable functions start with ansi_ prefix, and unexportable functions without them.

width(text)

ansi_width(text)

Returns visual width of given text.

substr(text, offset, width [, replacement])

ansi_substr(text, offset, width [, replacement])

Returns substring just like Perl's substr function, but string position is calculated by the visible width on the screen instead of number of characters.

If an optional replacement parameter is given, replace the substring by the replacement and return the entire string.

It does not cut the text in the middle of multi-byte character, of course. Its behavior depends on the implementation of lower module.
