Fabian Boehm 38b24c2325 docs: Use :doc: role when linking to commands
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.

.. _cmd-fish_breakpoint_prompt:
fish_breakpoint_prompt - define the prompt when stopped at a breakpoint
=======================================================================
Synopsis
--------
.. synopsis::
fish_breakpoint_prompt
::
function fish_breakpoint_prompt
...
end
Description
-----------
``fish_breakpoint_prompt`` is the prompt function when asking for input in response to a :doc:`breakpoint <breakpoint>` command.
The exit status of commands within ``fish_breakpoint_prompt`` will not modify the value of :ref:`$status <variables-status>` outside of the ``fish_breakpoint_prompt`` function.
``fish`` ships with a default version of this function that displays the function name and line number of the current execution context.
Example
-------
A simple prompt that is a simplified version of the default debugging prompt::
function fish_breakpoint_prompt -d "Write out the debug prompt"
set -l function (status current-function)
set -l line (status current-line-number)
set -l prompt "$function:$line >"
echo -ns (set_color $fish_color_status) "BP $prompt" (set_color normal) ' '
end
