3. 8 5 Compound Completion The package slime c p c provides a different symbol completion algorithm which per forms completion in parallel over the hyphen delimited sub words of a symbol name Formally this means that a b c can complete to any symbol matching the regular ex pression a b c where dot matches anything but a hyphen Examples give a more intuitive feeling e m v b completes to multiple value bind e w open is ambiguous it completes to either with open file or with open stream The symbol is expanded to the longest common completion with open and the point is placed at the first point of ambiguity which in this case is the end e w stream completes to with open stream The variable slime c p c unambiguous prefix p specifies where point should be placed after completion E g the possible completions for f o are finish output and force output By the default point is moved after the f because that is the unambiguous prefix If slime c p c unambiguous prefix p is nil point moves to the end of the inserted text after the o in this case In addition slime c p c provides completion for character names mostly useful for Unicode aware implementations CL USER Sp lt TAB gt Here SLIME will usually complete the character to Space but in a Unicode aware implementation this might provide the following completions Space Space Sparkle Spherical Angle Spherical Angle Opening Left Sph

At this point SLIME is up and running and you can start exploring 2 5 Setup Tuning This section explains ways to reduce SLIME s startup time and how to configure SLIME for multiple Lisp systems Please proceed with this section only if your basic setup works If you are happy with the basic setup skip this section For contrib modules see Section 8 1 Loading Contribs page 30 Chapter 2 Getting started 4 2 5 1 Autoloading The basic setup loads SLIME always even if you don t use SLIME Emacs will start up a little faster if we load SLIME only on demand To achieve that you have to change your 7 emacs slightly setq inferior lisp program the path to your Lisp system add to list load path the path of your slime directory require slime autoloads slime setup The only difference compared to the basic setup is the line require slime autoloads It tells Emacs that the rest of SLIME should be loaded automatically when one of the commands M x slime or M x slime connect is executed the first time 2 5 2 Multiple Lisps By default the command M x slime starts the program specified with inferior lisp program If you invoke M x slime with a prefix argument Emacs prompts for the program which should be started instead If you need that frequently or if the command involves long filenames it s more convenient to set the slime lisp implementations variable in your emacs For example here we d

UCL and SBCL and receives a callback when data is available In this style requests from Emacs are only detected and processed when Lisp enters the event loop This style is simple and predictable SIGIO This style uses signal driven I O with a SIGIO signal handler Lisp receives requests from Emacs along with a signal causing it to interrupt whatever it is doing to serve the request This style has the advantage of responsiveness since Emacs can perform operations in Lisp even while it is busy doing other things It also allows Emacs to issue requests concurrently e g to send one long running request like compilation and then interrupt that with several short requests before it completes The disadvantages are that it may conflict with other uses of SIGIO by Lisp code and it may cause untold havoc by interrupting Lisp at an awkward moment SPAWN This style uses multiprocessing support in the Lisp system to execute each request in a separate thread This style has similar properties to SIGIO but it does not use signals and all requests issued by Emacs can be executed in parallel The default request handling style is chosen according to the capabilities of your Lisp system The general order of preference is SPAWN then SIGIO then FD HANDLER with NIL as a last resort You can check the default style by calling SWANK BACKEND PREFERRED COMMUNICATION STYLE You can also override the default by setting SWANK COMMUNICATION STYLE
