The package implements the -\fBregistry\fR Tcl command. This command is only supported on the -Windows platform. Warning: this command should be used with caution -as a corrupted registry can leave your system in an unusable state. -.PP -\fIKeyName\fR is the name of a registry key. Registry keys must be -one of the following forms: -.RS -.PP -\fB\e\e\fIhostname\fB\e\fIrootname\fB\e\fIkeypath\fR -.PP -\fIrootname\fB\e\fIkeypath\fR -.PP -\fIrootname\fR -.RE -.PP -\fIHostname\fR specifies the name of any valid Windows -host that exports its registry. The \fIrootname\fR component must be -one of \fBHKEY_LOCAL_MACHINE\fR, \fBHKEY_USERS\fR, -\fBHKEY_CLASSES_ROOT\fR, \fBHKEY_CURRENT_USER\fR, -\fBHKEY_CURRENT_CONFIG\fR, \fBHKEY_PERFORMANCE_DATA\fR, or -\fBHKEY_DYN_DATA\fR. The \fIkeypath\fR can be one or more -registry key names separated by backslash (\fB\e\fR) characters. -.PP -.VS 8.6 -The optional \fI\-mode\fR argument indicates which registry to work -with; when it is \fB\-32bit\fR the 32-bit registry will be used, and -when it is \fB\-64bit\fR the 64-bit registry will be used. If this -argument is omitted, the system's default registry will be the subject -of the requested operation. -.VE 8.6 -.PP -\fIOption\fR indicates what to do with the registry key name. Any -unique abbreviation for \fIoption\fR is acceptable. The valid options -are: -.TP -\fBregistry broadcast \fIkeyName\fR ?\fB\-timeout \fImilliseconds\fR? -. -Sends a broadcast message to the system and running programs to notify them -of certain updates. This is necessary to propagate changes to key registry -keys like Environment. The timeout specifies the amount of time, in -milliseconds, to wait for applications to respond to the broadcast message. -It defaults to 3000. The following example demonstrates how to add a path -to the global Environment and notify applications of the change without -requiring a logoff/logon step (assumes admin privileges): -.RS -.PP -.CS -set regPath [join { - HKEY_LOCAL_MACHINE - SYSTEM - CurrentControlSet - Control - {Session Manager} - Environment -} "\e\e"] -set curPath [\fBregistry get\fR $regPath "Path"] -\fBregistry set\fR $regPath "Path" "$curPath;$addPath" -\fBregistry broadcast\fR "Environment" -.CE -.RE -.TP -\fBregistry delete \fIkeyName\fR ?\fIvalueName\fR? -. -If the optional \fIvalueName\fR argument is present, the specified -value under \fIkeyName\fR will be deleted from the registry. If the -optional \fIvalueName\fR is omitted, the specified key and any subkeys -or values beneath it in the registry hierarchy will be deleted. If -the key could not be deleted then an error is generated. If the key -did not exist, the command has no effect. -.TP -\fBregistry get \fIkeyName valueName\fR -. -Returns the data associated with the value \fIvalueName\fR under the key -\fIkeyName\fR. If either the key or the value does not exist, then an -error is generated. For more details on the format of the returned -data, see \fBSUPPORTED TYPES\fR, below. -.TP -\fBregistry keys \fIkeyName\fR ?\fIpattern\fR? -. -If \fIpattern\fR is not specified, returns a list of names of all the -subkeys of \fIkeyName\fR. If \fIpattern\fR is specified, only those -names matching \fIpattern\fR are returned. Matching is determined -using the same rules as for \fBstring match\fR. If the -specified \fIkeyName\fR does not exist, then an error is generated. -.TP -\fBregistry set \fIkeyName\fR ?\fIvalueName data \fR?\fItype\fR?? -. -If \fIvalueName\fR is not specified, creates the key \fIkeyName\fR if -it does not already exist. If \fIvalueName\fR is specified, creates -the key \fIkeyName\fR and value \fIvalueName\fR if necessary. The -contents of \fIvalueName\fR are set to \fIdata\fR with the type -indicated by \fItype\fR. If \fItype\fR is not specified, the type -\fBsz\fR is assumed. For more details on the data and type arguments, -see \fBSUPPORTED TYPES\fR below. -.TP -\fBregistry type \fIkeyName valueName\fR -. -Returns the type of the value \fIvalueName\fR in the key -\fIkeyName\fR. For more information on the possible types, see -\fBSUPPORTED TYPES\fR, below. -.TP -\fBregistry values \fIkeyName\fR ?\fIpattern\fR? -. -If \fIpattern\fR is not specified, returns a list of names of all the -values of \fIkeyName\fR. If \fIpattern\fR is specified, only those -names matching \fIpattern\fR are returned. Matching is determined -using the same rules as for \fBstring match\fR. -.SH "SUPPORTED TYPES" -Each value under a key in the registry contains some data of a -particular type in a type-specific representation. The \fBregistry\fR -command converts between this internal representation and one that can -be manipulated by Tcl scripts. In most cases, the data is simply -returned as a Tcl string. The type indicates the intended use for the -data, but does not actually change the representation. For some -types, the \fBregistry\fR command returns the data in a different form to -make it easier to manipulate. The following types are recognized by the -registry command: -.TP 17 -\fBbinary\fR -. -The registry value contains arbitrary binary data. The data is represented -exactly in Tcl, including any embedded nulls. -.TP -\fBnone\fR -. -The registry value contains arbitrary binary data with no defined -type. The data is represented exactly in Tcl, including any embedded -nulls. -.TP -\fBsz\fR -. -The registry value contains a null-terminated string. The data is -represented in Tcl as a string. -.TP -\fBexpand_sz\fR -. -The registry value contains a null-terminated string that contains -unexpanded references to environment variables in the normal Windows -style (for example, -.QW %PATH% ). -The data is represented in Tcl as a string. -.TP -\fBdword\fR -. -The registry value contains a little-endian 32-bit number. The data is -represented in Tcl as a decimal string. -.TP -\fBdword_big_endian\fR -. -The registry value contains a big-endian 32-bit number. The data is -represented in Tcl as a decimal string. -.TP -\fBlink\fR -. -The registry value contains a symbolic link. The data is represented -exactly in Tcl, including any embedded nulls. -.TP -\fBmulti_sz\fR -. -The registry value contains an array of null-terminated strings. The -data is represented in Tcl as a list of strings. -.TP -\fBresource_list\fR -. -The registry value contains a device-driver resource list. The data -is represented exactly in Tcl, including any embedded nulls. -.PP -In addition to the symbolically named types listed above, unknown -types are identified using a 32-bit integer that corresponds to the -type code returned by the system interfaces. In this case, the data -is represented exactly in Tcl, including any embedded nulls. -.SH "PORTABILITY ISSUES" -The registry command is only available on Windows. -.SH EXAMPLE -Print out how double-clicking on a Tcl script file will invoke a Tcl -interpreter: -.PP -.CS -package require registry -set ext .tcl - -# Read the type name -set type [\fBregistry get\fR HKEY_CLASSES_ROOT\e\e$ext {}] -# Work out where to look for the command -set path HKEY_CLASSES_ROOT\e\e$type\e\eShell\e\eOpen\e\ecommand -# Read the command! -set command [\fBregistry get\fR $path {}] - -puts "$ext opens with $command" -.CE -.SH KEYWORDS -registry -'\" Local Variables: -'\" mode: nroff -'\" End: |
