Synopsis
|
|
--------
|
|
|
|
::
|
|
|
|
function fish_breakpoint_prompt
|
|
...
|
|
end
|
|
|
|
|
|
Description
|
|
-----------
|
|
|
|
By defining the ``fish_breakpoint_prompt`` function, the user can choose a custom prompt when asking for input in response to a :ref:`breakpoint <cmd-breakpoint>` command. The ``fish_breakpoint_prompt`` function is executed when the prompt is to be shown, and the output is used as a prompt.
|
|
|
|
The exit status of commands within ``fish_breakpoint_prompt`` will not modify the value of `$status <index.html#variables-status>`__ outside of the ``fish_breakpoint_prompt`` function.
|
|
|
|
``fish`` ships with a default version of this function that displays the function name and line number of the current execution context.
|
|
|
|
|
|
Example
|
|
-------
|
|
|
|
A simple prompt that is a simplified version of the default debugging prompt::
|
|
|
|
function fish_breakpoint_prompt -d "Write out the debug prompt"
|
|
set -l function (status current-function)
|
|
set -l line (status current-line-number)
|
|
set -l prompt "$function:$line >"
|
|
echo -ns (set_color $fish_color_status) "BP $prompt" (set_color normal) ' '
|
|
end
|
