Symbol (programming) - Support - Lisp - Examples

Examples

The following is a simple external representation of a Common Lisp symbol:

this-is-a-symbol

Symbols can contain whitespace (and all other characters):

|This is a symbol with whitespace|

In Common Lisp symbols with a leading colon in their printed representations are keyword symbols. These are interned in the keyword package.

:keyword-symbol

A printed representation of a symbol may include a package name. Two colons are written between the name of the package and the name of the symbol.

package-name::symbol-name

Packages can export symbols. Then only one colon is written between the name of the package and the name of the symbol.

package:exported-symbol

Famous quotes containing the word examples:

    “In the examples that I here bring in of what I have [read], heard, done or said, I have refrained from daring to alter even the smallest and most indifferent circumstances. My conscience falsifies not an iota; for my knowledge I cannot answer.”
    —Michel de Montaigne (1533–1592)

    “No rules exist, and examples are simply life-savers answering the appeals of rules making vain attempts to exist.”
    —André Breton (1896–1966)

    “It is hardly to be believed how spiritual reflections when mixed with a little physics can hold people’s attention and give them a livelier idea of God than do the often ill-applied examples of his wrath.”
    —G.C. (Georg Christoph)
