It sources Tcl code from a Text resource. +Currently only sources the resource by name, file IDs may be supported +at a later date. +.PP +\fBTcl_MacConvertTextResource\fR converts a TEXT resource into a Tcl +suitable string. It mallocs the returned memory, converts ``\\r'' to +``\\n'', and appends a null. The caller has the responsibility for +freeing the memory. +.PP +\fBTcl_MacFindResource\fR provides a higher level interface for +loading resources. It is used by \fBresource read\fR. +.PP +\fBTcl_NewOSTypeObj\fR is used to create a new resource name type +object. The object type is "ostype". +.PP +\fBTcl_SetOSTypeObj\fR modifies an object to be a resource type and to +have the specified long value. +.PP +\fBTcl_GetOSTypeFromObj\fR attempts to return an int from the Tcl +object "objPtr". If the object is not already an int, an attempt will +be made to convert it to one. +.PP +\fBTcl_MacSetEventProc\fR sets the event handling procedure for the +application. This function will be passed all incoming Mac events. +This function usually controls the console or some other entity like +Tk. + +.SH RESOURCE TYPES +.PP +Resource types are 4-byte values used by the macintosh resource +facility to tag parts of the resource fork in a file so that the OS +knows how to handle them.

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 |
