Workbench ARexx Port

Workbench acts as an ARexx host under the name of "WORKBENCH". It supports a number of commands as will be described below. Note that for the ARexx interface to work, rexxsyslib.library must be installed (this library is part of a regular Workbench installation) and the RexxMast program must have been started.

ACTIVATEWINDOW command

Purpose: This command will attempt to make a window the active one.

Format: ACTIVATEWINDOW [WINDOW] <ROOT|Drawer name>

Template: ACTIVATEWINDOW WINDOW

Parameters

WINDOW

Either "ROOT" to activate the Workbench root window (where volume icons and AppIcons live) or the fully qualified name of a drawer window to activate. Note that the drawer window must already be open.

If no WINDOW parameter is specified, this command will try to operate on the currently active Workbench window.

Errors: 10 - If the named window cannot be activated. The error code will be placed in the WORKBENCH.LASTERROR variable.

Result: -

Notes: If you choose to have a window activated that is not the root window you must make sure that the window name is given as a fully qualified path name. For example "Work:" is a fully qualified name, and so is "SYS:Utilities". "Devs/Printers" would not be a fully qualified name. A fully qualified name always contains the name of an assignment, a volume or a device.

Example

/* Activate the root window. */

ADDRESS workbench ACTIVATEWINDOW root /* Activate the "Work:" partition's window. */ ACTIVATEWINDOW 'Work:'

CHANGEWINDOW command

Purpose: This command will attempt to change the size and the position of a window.

Format: CHANGEWINDOW [WINDOW] <ROOT|ACTIVE|Drawer name> [[LEFTEDGE] <new left edge position>][[TOPEDGE] <new top edge position>][[WIDTH] <new window width>][[HEIGHT] <new window height>]

Template: CHANGEWINDOW WINDOW,LEFTEDGE/N,TOPEDGE/N,WIDTH/N,HEIGHT/N

Parameter

WINDOW

Either "ROOT" to resize/move the Workbench root window (where volume icons and AppIcons live), "ACTIVE" to change the currently active Workbench window or the fully qualified name of a drawer window to change. Note that the drawer window must already be open.

If no WINDOW parameter is specified, this command will try to operate on the currently active Workbench window.

LEFTEDGE

New left edge window position.

TOPEDGE

New top edge window position.

WIDTH

New window width.

HEIGHT

New window height.

Errors: 10 - If the named window cannot be changed; this can also happen if you specified "ACTIVE" as the window name and none of the Workbench windows is currently active. The error code will be placed in the WORBENCH.LASTERROR variable.

Result: -

Notes: If you choose to have a window changed that is neither the root nor the active window you must make sure that the window name is given as a fully qualified path name. For example "Work:" is a fully qualified name, and so is "SYS:Utilities". "Devs/Printers" would not be a fully qualified name. A fully qualified name always contains the name of an assignment, a volume or a device.

Example

/* Change the root window; move it to position 10,30 and change its size to 200x100 pixels. */

ADDRESS workbench CHANGEWINDOW root LEFTEDGE 10 TOPEDGE 30 WIDTH 200 HEIGHT 100 /* Change the currently active window. */ CHANGEWINDOW active 20 40 200 100

DELETE command

Purpose: This command is for deleting files and drawers (and their contents).

Format: DELETE [NAME] <File or drawer name> [ALL]

Template: DELETE NAME/A,ALL/S

Parameters

NAME

Name of the file or drawer or volume to delete.

ALL

If the object in question is a drawer, attempt to delete the contents of the drawer as well as the drawer itself. If this option is not specified, the DELETE command will only attempt to delete the drawer itself, which may fail if the drawer is not yet empty.

Errors: 10 - If the named file, drawer or volume could not be found or could not be deleted.

Result: -

Notes: The file name given must be an absolute path, such as in "RAM:Empty". A relative path, such as "/fred/barney" will not work.

Example

/* Delete the contents of the drawer RAM:Empty". */

ADDRESS workbench DELETE 'RAM:Empty' ALL

FAULT command

Purpose: This command will return a human readable explanation corresponding to an error code.

Format: FAULT [CODE] <Error code>

Template: FAULT CODE/A/N

Parameters

CODE

Error code to return a human readable explanation for.

Errors: -

Result: -

Example

/* Query the error message corresponding to error code #205. */

ADDRESS workbench OPTIONS RESULTS FAULT 205 SAY result

GETATTR command

Purpose: This command will retrieve information from the Workbench database, such the names of the drawers currently open and the icons currently selected.

Format: GETATTR [OBJECT] <Object name> [NAME <Item name>][STEM <Name of stem variable>] [VAR <Variable name>]

Template: GETATTR OBJECT/A,NAME/K,STEM/K,VAR/K

Format: HELP [COMMAND <Command name>] [MENUS] [PROMPT]

Template: HELP COMMAND/K,MENUS/S,PROMPT/S

Parameters

COMMAND

Name of the command whose command template should be retrieved.

MENUS

Specify this parameter to retrieve a list of menu items currently available.

PROMPT

Specify this parameter to invoke the online help system.

If no parameter is provided, a list of supported commands will be returned.

Example

/* Retrieve the list of supported commands. */

ADDRESS workbench OPTIONS results HELP SAY result /* Retrieve the command template of the 'GETATTR' command. */ HELP COMMAND getattr SAY result /* Retrieve the list of available menu items. */ HELP MENUS SAY result

ICON command

Purpose: This command is for manipulating the icons displayed in a window.

Format: ICON [WINDOW] <Window name> <Icon name> .. <Icon name> [OPEN] [MAKEVISIBLE] [SELECT] [UNSELECT] [UP <Pixels>] [DOWN <Pixels>] [LEFT <Pixels>] [RIGHT <Pixels>] [X <Horizontal position>] [Y <Vertical position>] [ACTIVATE UP|DOWN|LEFT|RIGHT] [CYCLE PREVIOUS|NEXT] [MOVE IN|OUT]

Template: ICON WINDOW,NAMES/M,OPEN/S,MAKEVISIBLE/S,SELECT/S,UNSELECT/S, UP/N,DOWN/N,LEFT/N,RIGHT/N,X/N,Y/N,ACTIVATE/K,CYCLE/K, MOVE/K

Parameters

WINDOW

Name of the window whose icons should be manipulated. This can be "ROOT" to work on the Workbench root window (where volume icons and AppIcons live), "ACTIVE" to work on the currently active Workbench window or the fully qualified name of a drawer window. Note that the drawer window must already be open.

If no WINDOW parameter is specified, this command will try to operate on the currently active Workbench window.

NAMES

Names of the icons to manipulate.

OPEN

Specifies that the named icons should be opened.

MAKEVISIBLE

Specifies that the named icons should be made visible. This generally works well for the first icon in a list but does not always work for a whole list.

SELECT

Select the named icons.

UNSELECT

Unselect the named icons.

UP, DOWN, LEFT, RIGHT

Move the named icons by the specified number of pixels.

X, Y

Move the named icons to the specified position.

ACTIVATE

This command is for activating the icon closest to the currently selected icon in the window. "Activating" in this context means selecting an icon, whilst at the same time unselecting all others. Thus, the "active" icon is the only selected icon in the window.

You can indicate which direction the next icon to be activated should be searched for, relative to the currently active icon. "UP" searches upwards, "DOWN" searches downwards, "LEFT" searches to the left and "RIGHT" searches to the right.

CYCLE

This command is for cycling through all icons in a window, making each one the active one in turn (for a description of what "active" means in this context, see the "ACTIVATE" description above). You must indicate in which direction you want to cycle through the icons: you can either specify "PREVIOUS" or "NEXT".

MOVE

This command is not for moving icons but for moving through a file system hierarchy. Thus, moving "in" will open a drawer and moving "out" will open the drawer's parent directory. The "IN" parameter will cause the drawer represented by the active icon to be opened. Please note that an icon must be selected and it must be a drawer. The "OUT" parameter will open the drawer's parent directory, and it also requires that in the drawer there is an icon selected. This may sound strange, but this feature is not meant as a replacement for the "Open Parent" menu item.

Errors: 10 - If the named window cannot be found, none of the Workbench windows are currently active and the command was set to work on the currently active Workbench window. The error code will be placed in the WORKBENCH.LASTERROR variable.

Result: -

Example

/* Select the icons of the "Workbench" and "Work" volumes displayed in the root window. */

ADDRESS workbench ICON WINDOW root NAMES Workbench Work SELECT /* Open the "Workbench" volume icon displayed in the root window. */ ICON WINDOW root NAMES Workbench OPEN

INFO command

Purpose: This command is for opening the Workbench icon information requester.

Format: INFO [NAME] <File, drawer or volume name>

Template: INFO NAME/A

Parameters

NAME

Name of the file, drawer or volume to open the information window for.

Errors: 10 - If the named file, drawer or volume could not be found. The error code will be placed in the WORKBENCH.LASTERROR variable.

Result: -

Example

/* Open the information window for SYS:". */

ADDRESS workbench INFO NAME 'SYS:'

KEYBOARD command

Purpose: This command can be used to bind ARexx commands to key combinations.

Format: KEYBOARD [NAME] <Name of key combination> ADD|REMOVE [KEY <Key combination>] [CMD <ARexx command>]

Template: KEYBOARD NAME/A,ADD/S,REMOVE/S,KEY,CMD/F

Parameters

NAME

Name of the key combination to add or remove. Each key combination must have a name with which it is associated. The name must be unique.

ADD

This tells the KEYBOARD command to add a new keyboard combination. You will also need to specify the KEY and CMD parameters.

REMOVE

This tells the KEYBOARD command to remove an existing keyboard combination.

KEY

The keyboard combination to add; this must be in the same format as used by the Commodities programs.

CMD

This is the ARexx command to bind to the keyboard combination. The command can either be the name of an ARexx script to execute or a short ARexx program in a single line.

Errors: 10 - The command will fail if you tried to add a duplicate of an existing key combination or if the key combination to remove does not exist. The error code will be placed in the WORKBENCH.LASTERROR variable.

Result: -

Example

/* Bind an ARexx script to the [Control]+A key combination.

* When pressed, this will cause the ARexx script by the name * "test.wb" to be executed. ARexx will search for that program * in the "REXX:" directory. If no "test.wb" file can be found, ARexx will attempt to execute a script * by the name of "test.rexx". */ ADDRESS workbench KEYBOARD ADD NAME test1 KEY ,"ctrl a", CMD ,'test' /* Bind an ARexx script to the [Alt]+[F1] key combination. * When pressed, this will cause a short inline program to be * executed. */ KEYBOARD ADD NAME test2 KEY ,"alt f1", CMD "say 42" /* Bind an ARexx script to the [Shift]+[Help] key combination. * When pressed, this will cause the "Workbench About" menu item to be invoked. */ KEYBOARD ADD NAME test3 KEY ,"shift help", CMD "MENU INVOKE WORKBENCH.ABOUT" /* Remove the first key combination we added above. */ KEYBOARD REMOVE NAME test1

LOCKGUI command

Purpose: This command will block access to all Workbench drawer windows.

Format: LOCKGUI

Template: LOCKGUI

Parameters: -

Errors: -

Result: -

Notes: It takes as many UNLOCKGUI commands as there were LOCKGUI commands to make the Workbench drawer windows usable again. In other words, the LOCKGUI command "nests".

Example

/* Block access to all Workbench drawer windows. */

ADDRESS workbench LOCKGUI

MENU command

Purpose: This command is for invoking items of the Workbench menu, as if the user had selected them with the mouse and for adding/removing user menus.

MOVEWINDOW command

Purpose: This command will attempt to change the position of a window.

Format: MOVEWINDOW [WINDOW] <ROOT|ACTIVE|Drawer name> [[LEFTEDGE] <new left edge position>] [[TOPEDGE] <new top edge position>]

Template: MOVEWINDOW WINDOW,LEFTEDGE/N,TOPEDGE/N

Parameters

WINDOW

Either "ROOT" to move the Workbench root window (where volume icons and AppIcons live), "ACTIVE" to move the currently active Workbench window or the fully qualified name of a drawer window to change. Note that the drawer window must already be open.

If no WINDOW parameter is specified, this command will try to operate on the currently active Workbench window.

LEFTEDGE

New left edge window position.

TOPEDGE

New top edge window position.

Errors: 10 - If the named window cannot be moved; this can also happen if you specified "ACTIVE" as the window name and none of the Workbench windows is currently active. The error code will be placed in the WORKBENCH.LASTERROR variable.

Result: -

Notes: If you choose to have a window changed that is neither the root nor the active window you must make sure that the window name is given as a fully qualified path name. For example "Work:" is a fully qualified name, and so is "SYS:Utilities". "Devs/Printers" would not be a fully qualified name. A fully qualified name always contains the name of an assignment, a volume or a device.

Example

/* Move the root window to position 10,30. */

ADDRESS workbench MOVEWINDOW root LEFTEDGE 10 TOPEDGE 30 /* Move the currently active window. */ MOVEWINDOW active 20 40

Name of the drawer to be created.

Errors: 10 - If the named drawer could not be created.

Result: -

Notes: The drawer name given must be an absolute path, such as in "RAM:Empty". A relative path, such as "/fred/barney" will not work.

Example

/* Create a drawer by the name of "Empty" in the RAM disk. */

ADDRESS workbench NEWDRAWER 'RAM:Empty'

RENAME command

Purpose: This command is for renaming files, drawers and volumes.

Format: RENAME [OLDNAME] <Name of file/drawer/volume to rename> [NEWNAME] <New name of the file/drawer/volume>

Template: RENAME OLDNAME/A,NEWNAME/A

Parameters

OLDNAME

Name of the file/drawer/volume to be renamed. This must be an absolute path, such as in "RAM:Empty". A relative path, such as "/fred/barney", will not work.

NEWNAME

The new name to assign to the file/drawer/volume. This must not be an absolute or relative path. For example, "wilma" is valid new name, "/wilma" or "wilma:" would be invalid names.

Errors: 10 - If the object cannot be renamed.

Result: -

Notes: The RENAME command does not work like for example the AmigaDOS "Rename" command. For example, RENAME 'ram:empty' ,'newname' will rename the file 'RAM:empty' to 'RAM:newname'.

Example

/* Rename a drawer by the name of "Old" in the RAM disk to "New". */

ADDRESS workbench RENAME 'RAM:Old' 'New'

RX command

Purpose: This command is for executing ARexx scripts and commands.

Format: RX [CONSOLE] [ASYNC] [CMD] <Command to execute>

Template: RX CONSOLE/S,ASYNC/S,CMD/A/F

Parameters

CONSOLE

This switch indicates that a console (for default I/O) is needed.

ASYNC

This switch indicates that the command should be run asynchronously, i.e. the "RX" command will return as soon as ARexx has been instructed to run the command you specified. Otherwise, the "RX" command will wait for the specified ARexx command to complete execution.

COMMAND

This is the name of the ARexx program to execute.

Errors: 10 - If the given ARexx program could not be executed.

Result: -

Example

/* Execute an ARexx program by the name of 'test.wb';

* its output should be sent to a console window. */ ADDRESS workbench RX CONSOLE CMD 'test.wb'

SIZEWINDOW command

Purpose: This command will attempt to change the size of a window.

Format: SIZEWINDOW [WINDOW] <ROOT|ACTIVE|Drawer name> [[WIDTH] <new window width>] [[HEIGHT] <new window height>]

Template: SIZEWINDOW WINDOW,WIDTH/N,HEIGHT/N

Parameters

WINDOW

Either "ROOT" to resize the Workbench root window (where volume icons and AppIcons live), "ACTIVE" to resize the currently active Workbench window or the fully qualified name of a drawer window to change. Note that the drawer window must already be open.

If no WINDOW parameter is specified, this command will try to operate on the currently active Workbench window.

WIDTH

New window width.

HEIGHT

New window height.

Errors: 10 - If the named window cannot be resized; this can also happen if you specified "ACTIVE" as the window name and none of the Workbench windows is currently active. The error code will be placed in the WORKBENCH.LASTERROR variable.

Result: -

Notes: If you choose to have a window resized that is neither the root nor the active window you must make sure that the window name is given as a fully qualified path name. For example "Work:" is a fully qualified name, and so is "SYS:Utilities". "Devs/Printers" would not be a fully qualified name. A fully qualified name always contains the name of an assignment, a volume or a device.

Example

/* Change the root window size to 200x100 pixels. */

ADDRESS workbench SIZEWINDOW root 30 WIDTH 200 HEIGHT 100 /* Resize the currently active window. */ SIZEWINDOW active 200 100

UNLOCKGUI command

Purpose: This command will allow access to all Workbench drawer windows locked with the LOCKGUI command.

Format: UNLOCKGUI

Template: UNLOCKGUI

Parameters: -

Errors: -

Result: -

Notes: It takes as many UNLOCKGUI commands as there were LOCKGUI commands to make the Workbench drawer windows usable again. In other words, the LOCKGUI command "nests".

Example

/* Reallow access to all Workbench drawer windows. */

ADDRESS workbench UNLOCKGUI

UNZOOMWINDOW command

Purpose: This command will attempt to return a window to its original position and dimensions.

Format: UNZOOMWINDOW [WINDOW] <ROOT|ACTIVE|Drawer name>

Template: UNZOOMWINDOW WINDOW

Parameters

WINDOW

Name of the window to operate on. "ROOT" will use the Workbench root window (where volume icons and AppIcons live), "ACTIVE" will use the currently active Workbench window. Any other fully qualified path name will use the drawer window corresponding to the path.

If no WINDOW parameter is specified, this command will try to operate on the currently active Workbench window.

Errors: 10 - If the named window cannot be found. The error code will be placed in the WORKBENCH.LASTERROR variable.

Result: -

Example

/* Change the root window. */

ADDRESS workbench UNZOOMWINDOW root

VIEW command

Purpose: This command will change the position of the viewable display area of a window.

Format: VIEW [WINDOW] <ROOT|ACTIVE|Drawer name> [PAGE|PIXEL] [UP|DOWN|LEFT|RIGHT]

Template: VIEW WINDOW,PAGE/S,PIXEL/S,UP/S,DOWN/S,LEFT/S,RIGHT/S

Parameters

WINDOW

Either "ROOT" to change the Workbench root window view (where volume icons and AppIcons live), "ACTIVE" to change the currently active Workbench window view or the fully qualified name of a drawer window to change. Note that the drawer window must already be open.

If no WINDOW parameter is specified, this command will try to operate on the currently active Workbench window.

Moves the view up by about 1/8 of the window height. If PAGE is specified, moves the view up by a whole page. If PIXEL is specified, moves the view up by a single pixel.

DOWN

Moves the view down by about 1/8 of the window height. If PAGE is specified, moves the view down by a whole page. If PIXEL is specified, moves the view down by a single pixel.

LEFT

Moves the view left by about 1/8 of the window width. If PAGE is specified, moves the view left by a whole page. If PIXEL is specified, moves the view left by a single pixel.

RIGHT

Moves the view right by about 1/8 of the window width. If PAGE is specified, moves the view right by a whole page. If PIXEL is specified, moves the view right by a single pixel.

Errors: 10 - If the named window view cannot be changed; this can also happen if you specified "ACTIVE" as the window name and none of the Workbench windows is currently active. The error code will be placed in the WORKBENCH.LASTERROR variable.

Result: -

Notes: If you choose to have a window view changed that is neither the root nor the active window you must make sure that the window name is given as a fully qualified path name. For example "Work:" is a fully qualified name, and so is "SYS:Utilities". "Devs/Printers" would not be a fully qualified name. A fully qualified name always contains the name of an assignment, a volume or a device.

To find out about a window's current view position, use the GETATTR command and query the window's WINDOW.VIEW.LEFT and WINDOW.VIEW.TOP attributes.

Example

/* Change the root window view; move it up by a whole page. */

ADDRESS workbench VIEW root PAGE UP

WINDOW command

Purpose: This command will change, open, close or snapshot windows.

Format: WINDOW [WINDOWS] <Window name> .. <Window name> [OPEN|CLOSE] [SNAPSHOT] [ACTIVATE] [MIN|MAX] [FRONT|BACK] [CYCLE PREVIOUS|NEXT]

Parameters

WINDOWS

Names of the windows to operate on. This can be "ROOT" for the Workbench root window (where volume icons and AppIcons live), "ACTIVE" for the currently active Workbench window or the fully qualified name of a drawer window.

OPEN

Attempt to open the specified windows.

Close the specified windows. Note that if a window is closed no further operations (such as SNAPSHOT, ACTIVATE, etc.) can be performed on it.

SNAPSHOT

Snapshot the sizes and positions of the specified windows.

ACTIVATE

MIN

Resize the windows to their minimum dimensions.

MAX

Resize the windows to their maximum dimensions.

FRONT

Move the windows into the foreground.

BACK

Move the windows into the background.

CYCLE

This command operates on the currently active drawer window. You can specify either "PREVIOUS", to activate the previous drawer window in the list, or "NEXT", to activate the next following drawer window in the list.

Errors: 10 - If the named windows cannot be opened or operated on; this can also happen if you specified "ACTIVE" as a window name and none of the Workbench windows is currently active. The error code will be placed in the WORKBENCH.LASTERROR variable.

Result: -

Notes: If you choose to have a window operated on that is neither the root nor the active window you must make sure that the window name is given as a fully qualified path name. For example "Work:" is a fully qualified name, and so is "SYS:Utilities". "Devs/Printers" would not be a fully qualified name. A fully qualified name always contains the name of an assignment, a volume or a device.
