The name `NAME' and property key`PROPKEY' arguments below should be interned symbols. Identity matching is performed. -- procedure: getprop (getprop NAME PROPKEY [DEFVAL]) Returns the first property `PROPKEY' value of name `NAME', or the optional default value `DEFVAL', when no such property. When a default value is not supplied #f is assumed. -- procedure: putprop! (putprop! NAME [PROPKEY VALUE] ...) Sets the first property `PROPKEY' value of name `NAME' to the supplied value `VALUE'. Does not replace an existing property! -- procedure: setprop! (setprop! NAME [PROPKEY VALUE] ...) Sets the property `PROPKEY' value of name `NAME' to the supplied value `VALUE'. Replaces any existing property! -- procedure: remprop! (remprop! NAME [PROPKEY] ...) Removes the first property `PROPKEY' of name `NAME'. -- procedure: remprop/all! (remprop/all! NAME [PROPKEY]) Removes every property `PROPKEY' value of name `NAME' matching the specified key, or removes name when a key is not specified. -- procedure: get-proplist (get-proplist NAME [PROPKEY ...]) Returns the first property `PROPKEY' value of name `NAME' for every property key specified, as a property list. All properties returned when no key specified. -- procedure: get-properties (get-properties NAME [PROPKEY ...]) Returns the first property `PROPKEY' value of name `NAME' for every property key specified, as an association list. All properties returned when no key specified. -- procedure: rem-properties! (rem-properties! NAME PROPKEY ...) Removes the first property `PROPKEY' value of name `NAME' for every property specified. -- procedure: rem-properties/all! (rem-properties/all! NAME [PROPKEY ...]) Removes every property `PROPKEY' value of name `NAME' for every property specified, or deletes name when a key is not specified.  File: proplist.egg.info, Node: Disembodied property list, Next: Property list I/O, Prev: Property list, Up: Documentation 2.2 Disembodied property list ============================= Pre-2.2 CHICKEN-like property list procedures. These are not particularly useful, as no new functionality is provided. However, they allow the property list procedures to accept hash-tables, and do something reasonable. -- procedure: getprop (getprop HASHTABLE PROPKEY [DEFVAL]) Returns the property `PROPKEY' value of the hashtable `HASHTABLE', or the optional default value`DEFVAL', when no such property. When a default value is not supplied #f is assumed. -- procedure: putprop! (putprop! HASHTABLE [PROPKEY VALUE] ...) Sets the property `PROPKEY' value of the hashtable `HASHTABLE' to the supplied value `VALUE'. -- procedure: setprop! (setprop! HASHTABLE [PROPKEY VALUE] ...) Sets the property `PROPKEY' value of hashtable `HASHTABLE' to the supplied value `VALUE'. Replaces any existing property! -- procedure: remprop! (remprop! HASHTABLE PROPKEY ...) Removes the property `PROPKEY' from the hashtable `HASHTABLE'.  File: proplist.egg.info, Node: Property list I/O, Prev: Disembodied property list, Up: Documentation 2.3 Property list I/O ===================== Property list SRFI-10 support procedures. A reader-ctor is defined for the external text representation of a property list. -- procedure: print-proplist (print-proplist NAME [PORT]) Writes the external text representation of the property list for name `NAME' to the output port `PORT'. Port defaults to the (current-output-port). -- procedure: set-proplist! (set-proplist! NAME PROPLIST) Sets the property list for name `NAME' to the supplied property list `PROPLIST'. Though not an I/O operation this procedure is considered too dangerous for regular use and buried in this section.
