1 Introduction

Universally useful Lisp code that lives in package com.google.base.

The intent is that the base package only contains code that's highly likely to
be useful in every Lisp application.  Currently it contains:

    a nicer version of DEFCONSTANT
    a macro for generating simple PRINT-OBJECT methods
    a MISSING-ARGUMENT function for use in DEFCLASS forms
    functions for manipulating utf-8 strings stored as vectors of 8-bit octets
    common compiler optimization settings
    functions for extracting the prefix or suffix of a sequence
    Lisp type definitions for common C integer types

4 Packages

Packages are listed by definition order.

4.1 com.google.base

Basic code used by all applications. The code in BASE should be universally useful, since most packages will import BASE symbols by including
(:USE #:COM.GOOGLE.BASE) in their DEFPACKAGE form.

5 Definitions

Definitions are sorted by export status, category, package, and then by lexicographic order.

5.1 Exported definitions

5.1.1 Constants

Constant: +maximum-vector-index+

Largest valid vector index.

Package

type.lisp (file)

5.1.2 Special variables

Special Variable: *optimize-default*

Compiler optimization settings that emphasize debugging over speed. Most code should use these settings.

Package

com.google.base

Source

optimize.lisp (file)

Special Variable: *optimize-fast-unsafe*

Compiler optimization settings that emphasize speed at the expense of debugging and run-time safety. Only low-level performance sensitive code that has been extensively tested should use these settings.

Package

com.google.base

Source

optimize.lisp (file)

5.1.3 Macros

Macro: defconst NAME VALUE &optional DOCUMENTATION

Identical to CL:DEFCONSTANT except that the global constant variable NAME is bound to VALUE at compile time so it can be used in #. reader forms. Additionally, if the DEFCONST form is evaluated a second time, the constant is not rebound if the new value is EQUALP to the old. CL:DEFCONSTANT requires that the two values be EQL to avoid undefined behavior.

Package

com.google.base

Source

syntax.lisp (file)

Macro: define-print-object CLASS-NAME ACCESSOR-INFO

Generates a CL:PRINT-OBJECT generic function for class CLASS-NAME using ACCESSOR-INFO, a list containing elements of the form
(accessor initarg [format-string]).

If a format-string is not provided for a slot, then the generated PRINT-OBJECT function outputs nothing for that slot when *PRINT-READABLY* is false.

Given a POINT class with slots X, Y, and HIDDEN. The following DEFINE-PRINT-OBJECT form:

(define-print-object point
((x :x "x is ~D")
(y :y "y is ~D")
(hidden :hidden)))

expands to a PRINT-OBJECT function similar to:

(defmethod print-object ((point point) stream)
(if *print-readably*
(progn (write-string "#." stream)
(write ‘(make-instance ’point
:x ,(x point)
:y ,(y point)
:hidden ,(hidden point))
:stream stream))
(print-unreadable-object (point stream :type t :identity t)
(format stream "x is ~D y is ~D" (x point) (y point)))))

5.1.4 Functions

Function: make-octet-vector OCTET-COUNT &key INITIAL-CONTENTS

Create an OCTET-VECTOR containing OCTET-COUNT octets. If INITIAL-CONTENTS is not supplied, each element of the vector is initialized to zero. Otherwise, the vector is initialized to the contents of list INITIAL-CONTENTS.

Function: missing-argument ()

Signal an error indicating that an &OPTIONAL or &KEY argument is missing. Use (MISSING-ARGUMENT) as the default value of required &KEY function arguments and as the initform in DEFCLASS and DEFSTRUCT slot definition forms when the slot’s initform must always be supplied to MAKE-INSTANCE.
