string-pad - pad strings to a fixed width
=========================================
Synopsis
--------
.. BEGIN SYNOPSIS
::
string pad [(-r | --right)] [(-c | --char) CHAR] [(-w | --width) INTEGER] [STRING...]
.. END SYNOPSIS
Description
-----------
.. BEGIN DESCRIPTION
``string pad`` extends each STRING to the given visible width by adding CHAR to the left. That means the width of all visible characters added together, excluding escape sequences and accounting for $fish_emoji_width and $fish_ambiguous_width. It is the amount of columns in a terminal the STRING occupies.
The escape sequences reflect what *fish* knows about, and how it computes its output. Your terminal might support more escapes, or not support escape sequences that fish knows about.
If ``-r`` or ``--right`` is given, add the padding after a string.
If ``-c`` or ``--char`` is given, pad with CHAR instead of whitespace.
The output is padded to the maximum width of all input strings. If ``-w`` or ``--width`` is given, use at least that.
.. END DESCRIPTION
Examples
--------
.. BEGIN EXAMPLES
::
>_ string pad -w 10 abc abcdef
abc
abcdef
>_ string pad --right --char=🐟 "fish are pretty" "rich. "
fish are pretty
rich. 🐟🐟🐟🐟
>_ string pad -w$COLUMNS (date)
# Prints the current time on the right edge of the screen.

--------
- The :ref:`printf <cmd-printf>` command can do simple padding, for example ``printf %10s\n`` works like ``string pad -w10``.
- :ref:`string length <cmd-string-length>` with the ``--visible`` option can be used to show what fish thinks the width is.
