6 Functions and Special Forms

Each line here shows a name and then one of the words expr, fexpr or macro. In some cases there can also be special treatment of functions by the compiler so that they get compiled in-line.

abs expr

 
This takes one argument that should be a number – and returns its absolute value. In Common Lisp mode it would find the magnitude of a complex number, but in normal Standard Lisp mode the only cases that arise are integers are floating point values.

caadr expr

caar …cddddr expr

 
Names that start with c, then have a sequence of a or ds and finally r provide shorthand functions for chains of uses of car and cdr. Thus for instance (cadar x) has the same meaning as (car (cdr (car x))).

cadaar expr

caddar expr

cadddr expr

 
see caar and fourth.

caddr expr

 
see caar and third.

cadr expr

 
see caar and second.

car expr

 
For a non-empty list the function car will return the first element. For a dotted pair (created using cons) it extracts the first component. This is the fundamental low-level data structure access function in Lisp. See cdr for the function that returns the tail or a list or the second component of a dotted pair. In CSL any attempt to take car of an atom should be detected and will be treated as an error. If CSL had been compiled in Common Lisp mode (which is now not probable) a special exemption would apply and car and cdr of the empty lisp nil would be nil.

car!* expr

 
This function behaves like car except that if its argument is atomic then the argument is returned unaltered rather than that case being treated as an error.

library!-members expr

 
Returns a list of all the modules that could potentially be loaded using load!-module. See list!-modules to get a human readable display that looks more like the result of listing a directory, or modulep for checking the state of a particular named module.

list!-modules expr

 
This prints a human-readable display of the modules present in the current image files. This will include “InitialImage” which is the heap-image loaded at system startup. For example

> (list!-modules)  
 
File d:\csl\csl.img (dirsize 8  length 155016, Writable):  
  compat       Sat Jul 26 10:20:08 2008  position 556   size: 9320  
  compiler     Sat Jul 26 10:20:08 2008  position 9880  size: 81088  
  InitialImage Sat Jul 26 10:20:09 2008  position 90972 size: 64040  
 
nil

See library!-members and modulep for functions that make it possible for Lisp code to discover about the loadable modules that are available.

This is a destructive function in that it alters the data structure that it is given as its first argument by updating its car component. The result is the updated object. See rplacd for the corresponding function for updating the cdr component.
