Graphics.Text.Width
Description
This module provides functions to measure the terminal column width of characters and strings.
The functions provided in this module all ultimately make calls to
the C implementation in cbits/mk_wcwidth.c
. That code manages some
global state that carries a table of Unicode character widths. For
more details, see Install
, the C
code, and the "Multi-Column Character Support" section of the project
README
.

Documentation
safeWcwidth :: Char -> Int Source #
Returns the display width of a character. Assumes all characters with unknown widths are 0 width.
safeWcswidth :: String -> Int Source #
Returns the display width of a string. Assumes all characters with unknown widths are 0 width.
safeWctwidth :: Text -> Int Source #
Returns the display width of a text. Assumes all characters with unknown widths are 0 width.
safeWctlwidth :: Text -> Int Source #
Returns the display width of a lazy text. Assumes all characters with unknown widths are 0 width.
