This command is only supported on the Macintosh platform. Each Macintosh file consists of two \fIforks\fR: a \fIdata\fR fork and a \fIresource\fR fork. You use the normal open, puts, close, etc. commands to manipulate the data fork. You must use this command, however, to interact with the resource fork. \fIOption\fR indicates what resource command to perform. Any unique abbreviation for \fIoption\fR is acceptable. The valid options are: .TP \fBresource close \fIrsrcRef\fR Closes the given resource reference (obtained from \fBresource open\fR). Resources from that resource file will no longer be available. .TP \fBresource delete\fR ?\fIoptions\fR? \fIresourceType\fR This command will delete the resource specified by \fIoptions\fR and type \fIresourceType\fR (see RESOURCE TYPES below). The options give you several ways to specify the resource to be deleted. .RS .TP \fB\-id\fR \fIresourceId\fR If the \fB-id\fR option is given the id \fIresourceId\fR (see RESOURCE IDS below) is used to specify the resource to be deleted. The id must be a number - to specify a name use the \fB\-name\fR option. .TP \fB\-name\fR \fIresourceName\fR If \fB-name\fR is specified, the resource named \fIresourceName\fR will be deleted. If the \fB-id\fR is also provided, then there must be a resource with BOTH this name and this id. If no name is provided, then the id will be used regardless of the name of the actual resource. .TP \fB\-file\fR \fIresourceRef\fR If the \fB-file\fR option is specified then the resource will be deleted from the file pointed to by \fIresourceRef\fR. Otherwise the first resource with the given \fIresourceName\fR and or \fIresourceId\fR which is found on the resource file path will be deleted. To inspect the file path, use the \fIresource files\fR command. .RE .TP \fBresource files ?\fIresourceRef\fR? If \fIresourceRef\fRis not provided, this command returns a Tcl list of the resource references for all the currently open resource files. The list is in the normal Macintosh search order for resources. If \fIresourceRef\fR is specified, the command will return the path to the file whose resource fork is represented by that token. .TP \fBresource list \fIresourceType\fR ?\fIresourceRef\fR? List all of the resources ids of type \fIresourceType\fR (see RESOURCE TYPES below). If \fIresourceRef\fR is specified then the command will limit the search to that particular resource file. Otherwise, all resource files currently opened by the application will be searched. A Tcl list of either the resource name's or resource id's of the found resources will be returned. See the RESOURCE IDS section below for more details about what a resource id is. .TP \fBresource open \fIfileName\fR ?\fIaccess\fR? Open the resource for the file \fIfileName\fR. Standard file access permissions may also be specified (see the manual entry for \fBopen\fR for details). A resource reference (\fIresourceRef\fR) is returned that can be used by the other resource commands. An error can occur if the file doesn't exist or the file does not have a resource fork. However, if you open the file with write permissions the file and/or resource fork will be created instead of generating an error. .TP \fBresource read \fIresourceType\fR \fIresourceId\fR ?\fIresourceRef\fR? Read the entire resource of type \fIresourceType\fR (see RESOURCE TYPES below) and the name or id of \fIresourceId\fR (see RESOURCE IDS below) into memory and return the result. If \fIresourceRef\fR is specified we limit our search to that resource file, otherwise we search all open resource forks in the application. It is important to note that most Macintosh resource use a binary format and the data returned from this command may have embedded NULLs or other non-ASCII data. .TP \fBresource types ?\fIresourceRef\fR? This command returns a Tcl list of all resource types (see RESOURCE TYPES below) found in the resource file pointed to by \fIresourceRef\fR. If \fIresourceRef\fR is not specified it will return all the resource types found in every resource file currently opened by the application. .TP \fBresource write\fR ?\fIoptions\fR? \fIresourceType\fR \fIdata\fR This command will write the passed in \fIdata\fR as a new resource of type \fIresourceType\fR (see RESOURCE TYPES below). Several options are available that describe where and how the resource is stored. .RS .TP \fB\-id\fR \fIresourceId\fR If the \fB-id\fR option is given the id \fIresourceId\fR (see RESOURCE IDS below) is used for the new resource, otherwise a unique id will be generated that will not conflict with any existing resource. However, the id must be a number - to specify a name use the \fB\-name\fR option. .TP \fB\-name\fR \fIresourceName\fR If \fB-name\fR is specified the resource will be named \fIresourceName\fR, otherwise it will have the empty string as the name. .TP \fB\-file\fR \fIresourceRef\fR If the \fB-file\fR option is specified then the resource will be written in the file pointed to by \fIresourceRef\fR, otherwise the most recently open resource will be used. .TP \fB\-force\fR If the target resource already exists, then by default Tcl will not overwrite it, but raise an error instead. Use the -force flag to force overwriting the extant resource. .RE .SH "RESOURCE TYPES" Resource types are defined as a four character string that is then mapped to an underlying id. For example, \fBTEXT\fR refers to the Macintosh resource type for text. The type \fBSTR#\fR is a list of counted strings. All Macintosh resources must be of some type. See Macintosh documentation for a more complete list of resource types that are commonly used. .SH "RESOURCE IDS" For this command the notion of a resource id actually refers to two ideas in Macintosh resources. Every place you can use a resource Id you can use either the resource name or a resource number. Names are always searched or returned in preference to numbers. For example, the \fBresource list\fR command will return names if they exist or numbers if the name is NULL. .SH "PORTABILITY ISSUES" The resource command is only available on Macintosh. .SH "SEE ALSO" open(n) .SH KEYWORDS open, resource
