Article contents:== Outdated egg! This is an egg for CHICKEN 4, the unsupported old release. You're almost certainly looking for [[/eggref/5/macosx|the CHICKEN 5 version of this egg]], if it exists. If it does not exist, there may be equivalent functionality provided by another egg; have a look at the [[https://wiki.call-cc.org/chicken-projects/egg-index-5.html|egg index]]. Otherwise, please consider porting this egg to the current version of CHICKEN. [[tags: egg]] == macosx [[toc:]] == Documentation Very incomplete MacOS X Core API. === Environment Query ==== Usage <enscript language=scheme> (require-extension macosx-env) </enscript> ==== Notes ; {{STORE}} : {{(or #f (c-pointer SCDynamicStoreRef))}}. ==== machine-name <procedure>(machine-name) -> string</procedure> The machine name from core services. Probably not the same as {{(get-host-name)}}. ==== short-user-name <procedure>(short-user-name) -> string</procedure> The short name for the user. Based on the current process uid. ==== long-user-name <procedure>(long-user-name) -> string</procedure> The long name for the user. Based on the current process uid. ==== machine-location <procedure>(machine-location) -> vector</procedure> Returns a 4 element vector: ; LATITUDE : {{inexact}} ; Latitude in degrees north to 2 decimal places. ; LONGITUDE : {{inexact}} ; Longitude in degrees east to 2 decimal places. ; DLS-OFFSET : {{fixnum}} ; Number of seconds to add for daylight saving time. ; GMT-OFFSET : {{fixnum}} ; Number of seconds east of GMT, includes daylight saving time status. ==== metric? <procedure>(metric?) -> boolean</procedure> Using the metric system? ==== computer-name <procedure>(computer-name [STORE]) -> string</procedure> The computer name from system configuration. ==== console-user <procedure>(console-user [STORE]) -> (or boolean vector)</procedure> Returns a 3 element vector or {{#f}} for failure. ; NAME : {{string}} ; The (short) name of the console user. ; UID : {{fixnum}} ; The user id of the console user. ; GID : {{fixnum}} ; The group id of the console user. ==== local-host-name <procedure>(local-host-name [STORE]) -> string</procedure> The local host name from system configuration. Probably not the same as {{(get-host-name)}}. ==== location-name <procedure>(location-name [STORE]) -> string</procedure> The location. ==== session-info <procedure>(session-info) -> vector</procedure> Returns a 10 element vector: ; SESSION-ID : {{fixnum}} ; The security session identifier number. ; IS-ROOT : {{boolean}} ; A root session? ; HAS-GRAPHICS : {{boolean}} ; Has graphics access? ; HAS-TTY : {{boolean}} ; Has tty? ; IS-REMOTE : {{boolean}} ; Is a remote session? ; WAS-INITIALIZED : {{boolean}} ; Initialized? (see note below) ; SHORT-USER-NAME : {{string}} ; Short user name. ; USER-ID : {{fixnum}} ; User identification number. ; CONSOLE-SET : {{fixnum}} ; Console hardware number. ; LOGIN-COMPLETED : {{boolean}} ; Login operations complete? ; IS-USER-ACTIVE : {{boolean}} ; On console? The OS API behind {{WAS-INITIALIZED}} is unsupported as of macOS 10.7 so to indicate the value is {{(void)}}. Raises an {{osstatus-condition}} for failure. ==== main-bundle-path <procedure>(main-bundle-path) -> string</procedure> The full pathname of the currently running executable, including the program name. ==== tick-count <procedure>(tick-count) -> number</procedure> Returns an unsigned 32-bit integer that indicates the current number of ticks (1/60th of a second) since the system last started up. ==== delay <procedure>(delay TICKS) -> number</procedure> Suspend execution for the specified number of {{TICKS}}. Returns an unsigned integer that indicates the ticks after the delay. ==== gestalt <procedure>(gestalt SELECTOR) -> number</procedure> Calls the Gestalt Manager with specified {{SELECTOR}} and returns an unsigned 32-bit integer. ; {{SELECTOR}} : {{(or string symbol number)}}. An {{(or string symbol)}} is converted to a Macintosh 4-byte character value. The string length may not be greater than 4 but can be less; space padding will be performed. Raises an {{oserr-condition}} for failure. === Error Conditons ==== Usage <enscript language=scheme> (require-extension macosx-errors) </enscript> ==== osstatus-condition? <procedure>(osstatus-condition? OBJ) -> boolean</procedure> Is {{OBJ}} an {{osstatus}} {{condition}}? ==== oserr-condition? <procedure>(oserr-condition? OBJ) -> boolean</procedure> Is {{OBJ}} an {{oserr}} {{condition}}? === URL Support ==== Usage <enscript language=scheme> (require-extension macosx-url) </enscript> ==== open-url <procedure>(open-url URL)</procedure> Opens the {{(: URL string}} using the system-dependent default application. == Notes * The utility of {{gestalt}} is almost none now. == Bugs & Limitations * The {{macosx-env}} module is on ''life-support''. * {{sessionWasInitialized}} was removed as of MacOS 10.7 (Lion). == Requirements [[dollar]] [[check-errors]] [[condition-utils]] [[test]] [[setup-helper]] == Author [[/users/kon-lovett|Kon Lovett]] == Version history ; 2.2.0 : Remove {{osstatus-condition?}}, & {{oserr-condition?}} ; 2.1.4 : Fix for ticket #630. ; 2.1.3 : Gestalt defunct & sessionWasInitialized not Lion. ; 2.1.2 : Uses [[condition-utils]]. : 2.1.1 : ; 2.1.0 : Needs "check-errors" extension. ; 2.0.0 : Chicken 4 release. == License Copyright (C) 2009-2018 Kon Lovett.
