Strings

\[\begin{align*} [ \ \KEY{Type} \quad & \NAMEREF{strings} \\ \KEY{Funcon} \quad & \NAMEREF{string} \\ \KEY{Funcon} \quad & \NAMEREF{string-append} \\ \KEY{Funcon} \quad & \NAMEREF{to-string} \ ] \end{align*}\] \[\begin{align*} \KEY{Type} \quad & \NAMEDECL{strings} \leadsto \NAMEHYPER{../.}{Lists}{lists} ( \NAMEHYPER{../../Primitive}{Characters}{characters} ) \end{align*}\] \[\begin{align*} \KEY{Funcon} \quad & \NAMEDECL{string}( \VAR{C}\STAR : \NAMEHYPER{../../Primitive}{Characters}{characters}\STAR) : \TO \NAMEREF{strings} \\&\quad \leadsto [ \VAR{C}\STAR ] \end{align*}\]

Literal strings are written \(\SHADE{\STRING{C{\UNDERSCORE}1{.}{.}{.}C{\UNDERSCORE}n}}\). A double-quote or backslash needs to be escaped: \(\SHADE{\STRING{{.}{.}{.}{\BACKSLASH}{"}{.}{.}{.}}}\), \(\SHADE{\STRING{{.}{.}{.}{\BACKSLASH}{\BACKSLASH}{.}{.}{.}}}\).

\[\begin{align*} \KEY{Funcon} \quad & \NAMEDECL{string-append}( \VAR{S}\STAR : \NAMEREF{strings}\STAR) : \TO \NAMEREF{strings} \\&\quad \leadsto \NAMEHYPER{../.}{Lists}{list-append} ( \VAR{S}\STAR ) \end{align*}\] \[\begin{align*} \KEY{Built-in Funcon} \quad & \NAMEDECL{to-string}( \_ : \NAMEHYPER{../..}{Value-Types}{ground-values}) : \TO \NAMEREF{strings} \end{align*}\]

The strings returned by \(\SHADE{\NAMEREF{to-string} ( \VAR{GV} )}\) are unspecified, except that when \(\SHADE{\VAR{GV}}\) is already a string, it is returned unchanged.

\[\begin{align*} \KEY{Assert} \quad & \NAMEREF{to-string} ( \VAR{S} : \NAMEREF{strings} ) == \VAR{S} \end{align*}\]
