The Options Editor
While the Environment controls the Opus 5 visual display elements, the
Options settings provide control over many of the operational commands.
These functions are:-
Caching
For speed of operation, Opus 5 can internally buffer each directory list.
This is known as the Directory Cache.
*** See Fig 8-01 ***
Maximum number of dirs cached: Specify the number of internal buffers to
be allocated for directories. You may
use any value from one to 65535.
Disable directory caching: When selected, this turns off directory
caching.
85 Directory Opus 5
Re-read modified caches: When this option is selected, each cached
directory is monitored. If the contents of a
cached directory have changed when it is next
activated, Opus 5 will re-read the directory.
Copy
This controls the actions taken when Opus 5 copies files.
*** See Fig 8-02 ***
Update destination free space: Once the copy has finished, this option
causes Opus 5 to recalculate the free
space remaining on the destination drive.
Set source archive bit: After Opus 5 copies a file, the archive bit of
the original file will be set if this option is
checked. This action can be used to indicate
that the file had been archived.
Also copy source's: These flags tell Opus 5 that when it copies a file,
it must also copy these parts of the file
information as well. You may select all, none, or
any combination of these options.
Delete
Major warning messages can be provided when deleting files and
directories. Select as required from the following:-.
Commencing delete: Tells Opus 5 to check with you before actually
starting to delete. A very useful option. It's
always better to be safe than sorry.
86 Directory Opus 5
*** See Fig 8-03 ***
Deleting files: Tells Opus 5 to ask for confirmation before deleting
every file.
Deleting directories: Tells Opus 5 to ask for confirmation before
deleting directories.
Hide Method
These options allow you to specify and control the method Opus 5 will use
to iconify itself.
*** See Fig 8-04 ***
Clock: Opus 5 will iconify to a one line clock display window on
Workbench. To un-iconify the window, simply activate it by
clicking on it with the left mouse button, then press the right
mouse button.
Hotkey Only: Opus 5 will close all windows and not place any visual
indication on the Workbench screen. To un-iconify, press
the hotkey combination as defined in the PopKey field
below.
Directory Opus 5 87
+------------------------------------------------------------------+
| The hotkey combination is always active, even when Opus 5 is not |
| iconified. |
+------------------------------------------------------------------+
Pressing the hotkeys will have the following effects:-
* if Directory Opus 5 is iconified, it will be un-iconified;
* if the Directory Opus 5 screen is open, but at the back of the
display, it will be brought to the front;
* if the screen has been pulled down using the screen drag bar, it
will be brought to the top;
* if the screen is already at the front of the display, it will be
moved to the back.
AppIcon (Workbench Only): Opus 5 will open an icon on Workbench. Simply
double click on the icon to un-iconify it. When iconified as an appicon,
you can drop Workbench icons on the Directory Opus 5 appicon. This will
have the same effect as if you displayed the file in a Lister window and
double-clicked on it. For example, if you drop an IFF picture on the
appicon, it will call the Show command.
AppMenu (Workbench Only): Opus 5 will add a menu to the Workbench's
application Tools menu. To un-iconify, simply
select the Directory Opus 5 menu item.
PopKey: Here you may enter the system hot key combination. If the
string gadget is left blank, Opus will use the historic default
combination of Ctrl, left Shift, left Alt.
With Opus 5.5, key sequences are automatically recognised. You may
select any combination of Shift, Alt, Ctrl and Amiga qualifiers plus a
key. If you wish to manually enter your own key sequence, depress the
Caps Lock key first, then enter the desired command string. If you wish
to delete a previously entered hot key, you will need to depress the Caps
Lock key to enter string mode first, then clear the string. Note that if
you choose other than the default combination, you cannot just enter
qualifiers alone, you must enter a key as well.
88 Directory Opus 5
Icons
These options define how Opus 5 processes files with associated icons or
'.info' files.
*** See Fig 8-05 ***
Perform all actions on icons: When selected, whatever happens to a file
will happen to that file's icon as well.
For instance, if you delete the file DATA,
and the file DATA.info also exists, it
will be deleted too. If you rename the
file FROG to BUFFALO, then FROG.info (if
it exists) will be renamed as BUFFALO.info
automatically.
Select icons automatically: This option works in a similar way.
Whenever you select a file, its associated
.info file will also be selected (if it
exists).
Trap 'More' in default tool: When you double-click or Open a project
icon whose default tool is set to 'More',
the file's contents will be displayed in
the Opus 5 text viewer instead of invoking
the More program.
Locale
Directory Opus 5 uses the Amiga Locale system to allow you to use Opus 5
in a variety of countries with different languages. This is determined
automatically from the Locale options you have selected when you installed
your Amiga OS and Workbench. Opus 5 also provides some extra control over
the display of certain strings of data.
Directory Opus 5 89
*** See Fig 8-06 ***
Date Format: These options control the way Directory Opus 5 formats
dates. The Amiga's operating system uses the first setting
(DD-MMM-YY) by default, but you may choose whichever one
you prefer.
Misc. flags...
Name substitution: Causes words like Today, Tomorrow or Tuesday to be
substituted for a date, if appropriate.
12 hour clock: Chooses whether the clock format used by Directory Opus 5
is displayed in 12 hour or 24 hour format.
Thousands separator: Determines whether numbers have a separator between
thousands. The character is determined from the
current languages you have selected from the
Workbench Locale installation.
Miscellaneous
This requester lets you set various special options.
*** See Fig 8-07 ***
90 Directory Opus 5
Mouse buttons over inactive banks: With Opus 5.11, the window holding a
Listers or Button Bank behaved in a
manner similar to Workbench, where
you have to activate the window
before it can see any button events.
In Opus 5.5, this has changed! With
this option enabled, Button banks and
Listers will see the right and middle
mouse buttons even if their window is
not active. Also, It is now possible
to select a button from a button bank
with the left mouse button without
the button bank becoming active.
This leaves the active focus on the
current Lister.
Quick quit: When set, Opus 5 will quit immediately when asked to without
first asking for confirmation.
Extended lister key selection: With this turned on, you can quickly find
files in large directories even if many
files begin with the same letters. When
you type the first letter, a string
gadget will appear over the Lister
toolbar enabling you to type as much of
the filename as is necessary for it to
scroll into view. As soon as you begin
any other action the string gadget will
disappear once more.
Filetype Sniffer: If enabled, Opus will automatically run the
FindFiletype command when a file with no defined
Filetype is double-clicked. With the option turned
off, Opus will run the SmartRead command to view the
file as either text, ansi or hexadecimal.
Priority
The priority requester allows you to customise the task priorities used
by various parts of Opus 5.
*** See Fig 8-08 ***
Directory Opus 5 91
Main priority: This is the priority of the main Opus 5 process. You may
specify a higher or lower priority for when Opus is busy.
Listers: Each Opus 5 Lister runs a separate task which allows the
smoothest multitasking possible. You may set the priority that
all Listers will use for both normal and busy operation.
+-------------------------------------------------------------------+
| We recommend leaving the priorities at zero (0) unless you have a |
| clear understanding of Amiga scheduling and a very good reason to |
| change it! |
+-------------------------------------------------------------------+
Replace
This controls certain aspects of the requester which appears when copying
a file over another with the same name.
*** See Fig 8-09 ***
*** See Fig 8-10 ***
92 Directory Opus 5
Verbose 'Replace?' requester: Changes the requester from a simplified
display to one with a more 'user-friendly'
style showing extra information about the
difference between the two files.
Automatically check version: This option invokes a version check when
you attempt to replace an existing file and
reports the results of the version
comparison in the replace requester. If
turned off, the version check may be
performed manually from an extra button on
the replace requester.
+-----------------------------------------------------------------------+
| HINT: When replacing large files it is recommended that you turn this |
| option off, since searching for the version information on |
| large files can take some time. |
+-----------------------------------------------------------------------+
+-----------------------------------------------------------------------+
| The version check understands version information in libraries and |
| devices and also looks for the version string as recommended in the |
| Amiga Style Guide ( This is defined as "$VER: Name version.revision |
| <(DD/MM/YY)>" ). If the version information in the file does not |
| follow the recommended standard, Opus may report anomalous results. |
+-----------------------------------------------------------------------+
Obsolete Options - Options/Path Formats
In earlier versions of Opus, we used a special section called Path
Formats where you could define a special format for a specific path plus
add an special hot key for quick access to this path and format. With the
extra display modes and other features of Opus 5.5, a separate section for
this has become obsolete. However, you can still define specific path
formats but in a more powerful way than before. Now, you can save not
only the format for a Name Mode Lister but even the actual size, position
and display mode for any desired path. This can be done as follows:-
Path Format for Name Mode Lister
Display the desired path in a Name Mode Lister, invoke the Lister Format
Editor, set the required format, then select Save from the Format Editor.
Directory Opus 5 93
Size, Position and Display Mode for any Lister
Display the desired path in a Lister in the required display mode, size
and position the Lister to exactly where you wish it to appear on the
screen, and take a direct snapshot from the Lister/Snapshot menu or from
the Lister's RMB pop-up menu.
Hot Keys for a Special Path
In the HotKey Editor, add a new entry plus special hot key for your
desired directory path similar to the following:-
Command SCANDIR WorkDir: MODE=name
or maybe
Command SCANDIR WorkDir: NEW MODE=icon
The SCANDIR command gives you the power to display your chosen directory
exactly as required. Any special snapshots or previously saved display
format will be used for this path.
