wezterm.column_width(string)

Since: Version 20210502-130208-bff6815d

The functionality described in this section requires version 20210502-130208-bff6815d of wezterm, or a more recent version.

Given a string parameter, returns the number of columns that that text occupies in the terminal, which is useful together with format-tab-title and update-right-status to compute/layout tabs and status information.

This is different from string.len which returns the number of bytes that comprise the string.
