These Lisp variables can be configured via your ~/.swank.lisp file:
SWANK:*CONFIGURE-EMACS-INDENTATION* ¶This variable controls whether indentation styles for
&body-arguments in macros are discovered and sent to Emacs. It
is enabled by default.
SWANK:*GLOBALLY-REDIRECT-IO* ¶When T this causes the standard streams (*standard-output*,
etc) to be globally redirected to the REPL in Emacs.
When :STARTED-FROM-EMACS (default) redirects the output when
the lisp is launched from emacs (i.e. M-x slime), but not
from M-x slime-connect.
When NIL these streams are only temporarily redirected
to Emacs using dynamic bindings while handling requests. Note that
*standard-input* is currently never globally redirected into
Emacs, because it can interact badly with the Lisp’s native REPL by
having it try to read from the Emacs one.
SWANK:*GLOBAL-DEBUGGER* ¶When true (the default) this causes *DEBUGGER-HOOK* to be
globally set to SWANK:SWANK-DEBUGGER-HOOK and thus for SLIME
to handle all debugging in the Lisp image. This is for debugging
multithreaded and callback-driven applications.
SWANK:*SLDB-QUIT-RESTART* ¶This variable names the restart that is invoked when pressing q
(see sldb-quit) in SLDB. For SLIME evaluation requests this
is unconditionally bound to a restart that returns to a safe
point. This variable is supposed to customize what q does if an
application’s thread lands into the debugger (see
SWANK:*GLOBAL-DEBUGGER*).
(setf swank:*sldb-quit-restart* 'sb-thread:terminate-thread)
SWANK:*BACKTRACE-PRINTER-BINDINGS* ¶SWANK:*MACROEXPAND-PRINTER-BINDINGS*SWANK:*SLDB-PRINTER-BINDINGS*SWANK:*SWANK-PPRINT-BINDINGS*These variables can be used to customize the printer in various situations. The values of the variables are association lists of printer variable names with the corresponding value. E.g., to enable the pretty printer for formatting backtraces in SLDB, you can use:
(push '(*print-pretty* . t) swank:*sldb-printer-bindings*).
SWANK:*LOG-EVENTS* ¶Setting this variable to t causes all protocol messages
exchanged with Emacs to be printed to *TERMINAL-IO*. This is
useful for low-level debugging and for observing how SLIME works
“on the wire.” The output of *TERMINAL-IO* can be found in
your Lisp system’s own listener, usually in the buffer
*inferior-lisp*.
