string-pad - pad strings to a fixed width
=========================================

Synopsis
--------

.. BEGIN SYNOPSIS

.. 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 :envvar:`fish_emoji_width` and :envvar:`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.
