This makes it so we link to the very top of the document instead of a special anchor we manually include. So clicking e.g. :doc:`string <cmds/string>` will link you to cmds/string.html instead of cmds/string.html#cmd-string. I would love to have a way to say "this document from the root of the document path", but that doesn't appear to work, I tried `/cmds/string`. So we'll just have to use cmds/string in normal documents and plain `string` from other commands.

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.

Examples

.. BEGIN EXAMPLES

abc
|
|
abcdef
|
|
|
|
>_ string pad --right --char=🐟 "fish are pretty" "rich. "
|
|
fish are pretty
|
|
rich. 🐟🐟🐟🐟
|
|
|
|
>_ string pad -w$COLUMNS (date)

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