Sample text

Also, when an if expression is written, the true-or-false-test is usually written on the same line as the symbol if, but the action to carry out if the test is true, the “then-part”, is written on the second and subsequent lines. This makes the if expression easier to read. (if true-or-false-test action-to-carry-out-if-test-is-true) The true-or-false-test will be an expression that is evaluated by the Lisp interpreter. Here is an example that you can evaluate in the usual manner. The test is whether the number 5 is greater than the number 4.

The append-to-buffer function looks exactly like this. ) 36 Chapter 3: How To Write Function Definitions If a function does not have arguments, then interactive does not require any. Such a function contains the simple expression (interactive). The mark-whole-buffer function is like this. Alternatively, if the special letter-codes are not right for your application, you can pass your own arguments to interactive as a list. See section “Using Interactive” in The GNU Emacs Lisp Reference Manual, for more information about this advanced technique.

1 1 It is curious to track the path by which the word ‘argument’ came to have two different meanings, one in mathematics and the other in everyday English. According to the Oxford English Dictionary, the word derives from the Latin for ‘to make clear, prove’; thus it came to mean, by one thread of derivation, ‘the evidence offered as proof’, which is to say, ‘the information offered’, which led to its meaning in Lisp. But in the other thread of derivation, it came to mean ‘to assert in a manner against which others may make counter assertions’, which led to the meaning of the word as a disputation.
