Example text

A char-table can also specify a single value for a whole character set. Chapter 2: Lisp Data Types 21 The printed representation of a char-table is like a vector except that there is an extra ‘#^’ at the beginning. 6 [Char-Tables], page 93, for special functions to operate on char-tables. 9 [Case Tables], page 60). 9 [Categories], page 696). 21 [Display Tables], page 807). • Syntax tables (see Chapter 35 [Syntax Tables], page 684). 11 Bool-Vector Type A bool-vector is a one-dimensional array of elements that must be t or nil.

This chapter describes the purpose, printed representation, and read syntax of each of the standard types in GNU Emacs Lisp. Details on how to use these types can be found in later chapters. 1 Printed Representation and Read Syntax The printed representation of an object is the format of the output generated by the Lisp printer (the function prin1) for that object. Every data type has a unique printed representation. The read syntax of an object is the format of the input accepted by the Lisp reader (the function read) for that object.

When you evaluate an expression interactively, the Lisp interpreter first reads the textual representation of it, producing a Lisp object, and then evaluates that object (see Chapter 9 [Evaluation], page 110). However, evaluation and reading are separate activities. Reading returns the Lisp object represented by the text that is read; the object may or may not be evaluated later. 3 [Input Functions], page 271, for a description of read, the basic function for reading objects. 2 Comments A comment is text that is written in a program only for the sake of humans that read the program, and that has no effect on the meaning of the program.
