System Utilities version 2·30 - ReadMe file
---------------------------------------------
This application allows useful operations to be performed from the
RiscOS desktop:
- The current, library or user root directory can be set either by
name, or by dragging a file or directory to the icon bar. This
comes in very useful for applications such as compilers, which
expect the current directory to be set up.
- The current contexts can be displayed.
- A directory display can be opened directly on a currently set
context, or by an entered name.
- A file finder searches a directory tree for filenames matching a
given specification.
- System data can be saved by the normal RiscOS dragging method:
· Character set (as a BBC Font file)
· Configuration (CMOS RAM data)
· Wimp sprite pool, Wimp ROM sprites or system sprites
A saved configuration file can be reloaded.
- Key translation can be selected to make First Word Plus version
2 a bit more "keyboard-friendly".
Running
-------
The shared C library must be installed, as is usual with desktop
applications now. A WimpSlot of 96K is required.
Simply open a directory viewer on the !SysUtil application, and double-
click on it. It will install itself on the left of the icon bar, to
emphasise its association with (mainly) disc filing.
Interactive help is fully supported, and can be used to find out the
functions of all the windows and buttons.
Detailed information
--------------------
All options are controlled via the menu obtained by clicking MENU over
the SysUtil icon. The menu options, in order, are:
Info The normal RiscOS-style information box.
Contexts Allows the current directory context to be manipulated
or displayed. Has the sub-options:
Set Set a context; pops up the
"Set context" dialogue box. See
the relevant section below. Can
also be selected by clicking
ADJUST on the SysUtil icon, or
by dragging a file or directory
to it.
Show Displays the current directory
contexts. Can also be shown by
clicking SELECT on the SysUtil
icon.
Show after change If this option is set (ticked),
the contexts will be shown
automatically every time they
are changed by SysUtil.
Open filer Allows a desktop filer display to be opened directly.
Has the sub-options:
Current Open a display for the current
directory (@).
Volume root Open a display for the volume
root directory ($). For ADFS,
this has the same effect as
clicking on the drive icon on
the icon bar.
User root Open a display for the current
user root directory (&). For
NetFS, this has the same effect
as clicking on the net icon on
the icon bar.
Library Open a display for the current
library directory (%).
Enter Open a display for a directory
name entered in the menu box.
The pathname is translated and
expanded before use, so system
variables and any filing system
prefix can be used.
Find File Locate a file; pops up the "Find File" dialogue box.
See the relevant section below.
Save misc Saves the following as files. The "Save as" box is used
in the normal RiscOS way.
Character set Saves the current System Font as
a 'BBC Font' file, i.e. as a
sequence of VDU 23 statements
which can be *PRINTed to set up
those font definitions. The
upper and lower limits for the
range of characters to be saved
(in decimal) can be entered;
the lowest character that can be
saved is 32 (space) and the
highest is 255.
Configuration Saves the current CMOS RAM
settings as a 'Config' file
(type &FF2; this is an Acorn
allocated file type). All 240
bytes of memory are saved.
To reload the saved config-
uration, drag a Config file to
the SysUtil icon on the icon bar
and confirm that you really want
to reload it. Location zero
(the Econet station number)
cannot and will not be reloaded;
a special network administration
utility is required to do this.
A Ctrl-Break may be necessary to
recognise the new configuration.
Wimp sprites Save the sprites contained in
the RAM portion of the Wimp
sprite pool as a sprite file.
ROM sprites Save the ROM part of the Wimp
sprite pool as a sprite file.
System sprites Save the contents of the system
sprite area as a sprite file.
1stWord Keys When ticked, enables keyboard translation for use with
First Word Plus version 2. See the relevant section
below.
Quit Removes the application from memory.
Using "Set context"
-------------------
To set a directory context, pop up the "Set context" window from the
menu or by clicking ADJUST on the SysUtil icon.
To select what is to be set, tick the 'Current', 'Home' or 'Library'
option. The current setting for that context, on the current filing
system, is displayed in the 'Path' box.
To select the filing system to be used, if required, click on 'adfs',
'ram', 'net' or 'Special'. A filing system name, or existing one with
special fields included, can be entered in the box to the right of
'Special'.
To enter the current setting, click on '$', '@', '%' or '&' as
appropriate.
A pathname can be entered directly in the 'Path' box if required.
However, the most expedient way to use this is to drag a file, directory
or application to the window or to the SysUtil icon. The full pathname
of that object (or the directory part, in the case of a file) will be
entered. Clicking 'Up' will remove the last leaf name component of the
path.
When the correct path has been entered, clicking 'OK' will set the
selected context to that. If the "Show after change" option is set on,
all three contexts will be shown in a transient window.
Click 'Cancel' or the close box to close the window and not change the
current context.
Using "Find File"
-----------------
This option will search the directory tree for file names matching a
given name. Searching is done in the background, so other desktop work
can continue while the search is running.
Select the "Find File" option from the menu to display the window.
Enter the name to be searched for in the 'Name' box. The four options
to the right of this determine how the name is matched:
Exact The name is matched exactly as entered.
Containing Any file name which includes the entered
sequence of characters will match.
Arthur wildcard The normal RiscOS wildcard characters are recog-
nised (* matches any string, # matches any
character).
Unix wildcard Wildcard characters similar to those used on the
Unix (TM AT&T) system are recognised. * matches
any string, ? matches any character. []
encloses a set of characters, for example [abcd]
matches the letter 'a', 'b', 'c' or 'd'. A
range of characters can also be specified, for
example [a-e] matches the letter 'a', 'b', 'c',
'd' or 'e'. \ can be used to remove the special
meaning of any of these special characters.
When searching for files, a RiscOS file type can be entered (in hex) in
the 'Type' box to further restrict the search. The name of the file
type will be shown in the box to the right.
A directory for the search to begin from can be entered in the 'From'
box. Another way of doing this is to drag a directory or application to
the window or the SysUtil icon.
The options 'Files' and 'Directories' can be selected singly using
SELECT, or in combination using ADJUST, to define what is to be searched
for. 'Directories' will also find applications.
Select one of the 'Action' options to indicate what is to be done with
any matching objects found. 'List details' will simply show the
pathnames (relative to the search root), types and sizes in a listing
window. 'Open viewers' will open a directory viewer for the parent
directory of each object.
When all is set up, click on 'OK' and the search will start. It can be
halted by clicking on 'Abort'; normally the window is displayed until
the search is over.
First Word Plus keyboard translation
------------------------------------
One of the things that greatly annoys me about First Word Plus version 2
is the function key rearrangement that has been done (is there anybody
from GST reading this?). Reformat has moved off f12 - fair enough,
since this is used for another function in the RiscOS desktop - but it
has been put on f7, which is far too near the Delete Line (f8) key for
my liking, especially as there is no Undo facility to get back the line
lost when f8 is pressed by mistake. Copy Block has been lost from Ctrl-
f8 for no apparent reason, and Indent is too far away (on f9) from the
main keyboard area.
To this end, when the '1stWord Keys' option on the menu is selected
(ticked), certain key translations are performed as below. I find them
most useful.
Print This gives Reformat, identical to f7. This key is
easier to find than f7, and hitting an adjacent key by
mistake does not have disastrous effects.
Ctrl-f8 This gives Copy Block, identical to ^C (or to ^f8 on the
original 1stWord version).
Shift-Tab This gives an indent, identical to f9. Does nothing
when not in WP Mode.
