Symbol Munger

A Common Lisp library to make it easy to change the capitalization and spacing of a “sentence”. This is used for converting between space & capitalization rules of various systems.

• Converts to and from lisp, english, underscores and camel-case
• Useful for converting database column names to lisp-symbols and english column header names
• Useful for converting between common lisp variables names and javascript variable names
• Removes excess word separators along the way (:foo–bar ⇒ “Foo Bar”)
• All conversion “→” functions accept lisp-trees of strings, symbols, and other lisp objects.
• all lisp objects (other than the tree structure which is flattened) are converted by symbol-munger::%coerce-to-string into strings.
• Each object part is treated as a separate word

(s &key (capitalize :each-word) (word-separators #\space) word-separators-to-replace stream in-place) * Will recapitalize a string and replace word-separators with a standard one (in-place if desired and possible) * If s is a lisp tree, then each part will be %coerce-to-string'ed and treated as a separate part of the phrase being normalized (ie: each part implicitly starts a new word) * Will write to a stream if given it otherwise. * Defaults to capitalizing each word but can be any of * {:each-word :first-word T (:all is an alias for T) nil :but-first-word (likeJavaScript) } * word-separators are used to distinguish new words for the purposes of capitalization * The first of these will be used to replace word-separators-to-replace * word-separators-to-replace helps normalize word separators so that spaces or underscores become the appropriate word-separator. * If this contains :capitals it assumes capital letters indicate a new word separation

returns a string (new or the one passed in if in-place) unless :stream is provided"
