12.13.9 Other facilities

A number of other Lisp-specific facilities are available using the menus in the Editor.

If the current buffer is associated with a file that is part of a system as defined by defsystem , choose File > Browse Parent System to browse the system it is part of in the System Browser. See The System Browser for more information about this tool.

Choose Definitions > Undefine... to remove the current definitions from your Lisp image. Similarly, choose Buffers > Undefine... to remove the definitions in the current buffer or selected buffers. By selecting items in the buffers view, or the various definitions views, you can control over the definitions which can be removed with one command. Both of these commands prompt you for confirmation with a second chance to modify the list of definitions to remove.

Choose Definitions > Generic Function to describe the current definition in a Generic Function Browser. See The Generic Function Browser for more details.

Standard action commands can be found on the Expression menu, allowing you to perform a number of operations on the current expression. See Performing operations on selected objects for full details.

Choose Expression > Arguments to print the lambda list of the current expression in the echo area, if it is a function, generic function or method. This is the same as using the EMACS key command Alt+= , except that the current expression is automatically used.

Choose Expression > Value to display the value of the current expression in the echo area.

Choose Expression > Macroexpand or click in the toolbar to macroexpand the current form. The macroexpansion is printed in the Output tab, in the same way that compilation output is shown. Note how an in-package form containing the current package is printed with the macroexpansion, meaning that you can preform a further macroexpansion. Press Space when the cursor is at the end of the output window to return to the Text tab.

Choose Expression > Walk to recursively macroexpand the current form.
