ClipTool V38.1
**************
ClipTool is a Commodities Exchange program that among other things is a
graphic user interface to the Amiga system clipboard. It can function as
a storehouse for multiple text clips and it can use all the clipboard
units; thus you can move data from one unit to another. It is also
possible to load and save data to and from the clipboard. Its convenient
ARexx interface makes it easy to operate it by remote control. A simple
example script that shows how clipboard support can be added to the Ed
text editor is included.
[This is an unfinished version of the documentation. ClipTool was
intended as the prototype of a more ambitious clipboard tool, capable of
handling graphics, having scrollbars so you could move around the
clipped data, etc. Nothing has been done about the code and this
document for almost a year and I haven't got time to work on them in the
foreseeable future. For that reason, I have decided to release the
"package" in its unfinished state, hoping that somebody will pick it up
and improve it.

Distribution
*************
ClipTool is "free"; this means that everyone is free to use it and free
to redistribute it on a free basis. ClipTool is not in the public
domain; it is copyrighted and there are restrictions on its
distribution, but these restrictions are designed to permit everything
that a good cooperating citizen would want to do. What is not allowed
is to try to prevent others from further sharing any version of ClipTool
that they might get from you. The precise conditions are found in the
GNU General Public License that comes with ClipTool and also appears
following this section.
The easiest way to get a copy of ClipTool is from someone else who has
it. You need not ask for permission to do so, or tell any one else;
just copy it.
If you have access to the Internet, you can get the latest distribution
version of ClipTool from Aminet:
Scandinavia
`ftp.luth.se'
Switzerland
`litamiga.epfl.ch'
Germany
`ftp.uni-kl.de'
`ftp.uni-erlangen.de'
`ftp.cs.tu-berlin.de'

Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.
675 Mass Ave, Cambridge, MA 02139, USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
========
The licenses for most software are designed to take away your freedom
to share and change it. By contrast, the GNU General Public License is
intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by
the GNU Library General Public License instead.) You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not price.
Our General Public Licenses are designed to make sure that you have the
freedom to distribute copies of free software (and charge for this
service if you wish), that you receive source code or can get it if you
want it, that you can change the software or use pieces of it in new
free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid anyone
to deny you these rights or to ask you to surrender the rights. These
restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether gratis
or for a fee, you must give the recipients all the rights that you
have. You must make sure that they, too, receive or can get the source
code. And you must show them these terms so they know their rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
Finally, any free program is threatened constantly by software patents.
We wish to avoid the danger that redistributors of a free program will
individually obtain patent licenses, in effect making the program
proprietary. To prevent this, we have made it clear that any patent
must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and
modification follow.
TERMS AND CONDITIONS
1. This License applies to any program or other work which contains a
notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The "Program",
below, refers to any such program or work, and a "work based on
the Program" means either the Program or any derivative work under
copyright law: that is to say, a work containing the Program or a
portion of it, either verbatim or with modifications and/or
translated into another language. (Hereinafter, translation is
included without limitation in the term "modification".) Each
licensee is addressed as "you".
Activities other than copying, distribution and modification are
not covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the
Program is covered only if its contents constitute a work based on
the Program (independent of having been made by running the
Program). Whether that is true depends on what the Program does.
2. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any
warranty; and give any other recipients of the Program a copy of
this License along with the Program.
You may charge a fee for the physical act of transferring a copy,
and you may at your option offer warranty protection in exchange
for a fee.
3. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 2
above, provided that you also meet all of these conditions:
* You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
* You must cause any work that you distribute or publish, that
in whole or in part contains or is derived from the Program
or any part thereof, to be licensed as a whole at no charge
to all third parties under the terms of this License.
* If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display
an announcement including an appropriate copyright notice and
a notice that there is no warranty (or else, saying that you
provide a warranty) and that users may redistribute the
program under these conditions, and telling the user how to
view a copy of this License. (Exception: if the Program
itself is interactive but does not normally print such an
announcement, your work based on the Program is not required
to print an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the
Program, and can be reasonably considered independent and separate
works in themselves, then this License, and its terms, do not
apply to those sections when you distribute them as separate
works. But when you distribute the same sections as part of a
whole which is a work based on the Program, the distribution of
the whole must be on the terms of this License, whose permissions
for other licensees extend to the entire whole, and thus to each
and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or
contest your rights to work written entirely by you; rather, the
intent is to exercise the right to control the distribution of
derivative or collective works based on the Program.
In addition, mere aggregation of another work not based on the
Program with the Program (or with a work based on the Program) on
a volume of a storage or distribution medium does not bring the
other work under the scope of this License.
4. You may copy and distribute the Program (or a work based on it,
under Section 3) in object code or executable form under the terms
of Sections 2 and 3 above provided that you also do one of the
following:
* Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of
Sections 2 and 3 above on a medium customarily used for
software interchange; or,
* Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 2 and 3 above on a
medium customarily used for software interchange; or,
* Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with
such an offer, in accord with the previous Subsection.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus
any associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However,
as a special exception, the source code distributed need not
include anything that is normally distributed (in either source or
binary form) with the major components (compiler, kernel, and so
on) of the operating system on which the executable runs, unless
that component itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
5. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this
License. However, parties who have received copies, or rights,
from you under this License will not have their licenses
terminated so long as such parties remain in full compliance.
6. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so,
and all its terms and conditions for copying, distributing or
modifying the Program or works based on it.
7. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program
subject to these terms and conditions. You may not impose any
further restrictions on the recipients' exercise of the rights
granted herein. You are not responsible for enforcing compliance
by third parties to this License.
8. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent
issues), conditions are imposed on you (whether by court order,
agreement or otherwise) that contradict the conditions of this
License, they do not excuse you from the conditions of this
License. If you cannot distribute so as to satisfy simultaneously
your obligations under this License and any other pertinent
obligations, then as a consequence you may not distribute the
Program at all. For example, if a patent license would not permit
royalty-free redistribution of the Program by all those who
receive copies directly or indirectly through you, then the only
way you could satisfy both it and this License would be to refrain
entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable
under any particular circumstance, the balance of the section is
intended to apply and the section as a whole is intended to apply
in other circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of
any such claims; this section has the sole purpose of protecting
the integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is
willing to distribute software through any other system and a
licensee cannot impose that choice.
This section is intended to make thoroughly clear what is believed
to be a consequence of the rest of this License.
9. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces,
the original copyright holder who places the Program under this
License may add an explicit geographical distribution limitation
excluding those countries, so that distribution is permitted only
in or among countries not thus excluded. In such case, this
License incorporates the limitation as if written in the body of
this License.
10. The Free Software Foundation may publish revised and/or new
versions of the General Public License from time to time. Such new
versions will be similar in spirit to the present version, but may
differ in detail to address new problems or concerns.
11. Each version is given a distinguishing version number. If the
Program specifies a version number of this License which applies
to it and "any later version", you have the option of following
the terms and conditions either of that version or of any later
version published by the Free Software Foundation. If the Program
does not specify a version number of this License, you may choose
any version ever published by the Free Software Foundation.
12. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the
author to ask for permission. For software which is copyrighted by
the Free Software Foundation, write to the Free Software
Foundation; we sometimes make exceptions for this. Our decision
will be guided by the two goals of preserving the free status of
all derivatives of our free software and of promoting the sharing
and reuse of software generally.
NO WARRANTY
13. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO
WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE
LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS
AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT
LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS
FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND
PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE
DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR
OR CORRECTION.
14. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY
MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE
LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL,
INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR
INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU
OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY
OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN
ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
Appendix: How to Apply These Terms to Your New Programs
=======================================================
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these
terms.
To do so, attach the following notices to the program. It is safest to
attach them to the start of each source file to most effectively convey
the exclusion of warranty; and each file should have at least the
"copyright" line and a pointer to where the full notice is found.
ONE LINE TO GIVE THE PROGRAM'S NAME AND A BRIEF IDEA OF WHAT IT DOES.
Copyright (C) 19YY NAME OF AUTHOR
This program is free software; you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation; either version 2 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License
along with this program; if not, write to the Free Software
Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) 19YY NAME OF AUTHOR
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the
appropriate parts of the General Public License. Of course, the
commands you use may be called something other than `show w' and `show
c'; they could even be mouse-clicks or menu items--whatever suits your
program.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary. Here a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
`Gnomovision' (which makes passes at compilers) written by James Hacker.
SIGNATURE OF TY COON, 1 April 1989
Ty Coon, President of Vice
This General Public License does not permit incorporating your program
into proprietary programs. If your program is a subroutine library, you
may consider it more useful to permit linking proprietary applications
with the library. If this is what you want to do, use the GNU Library
General Public License instead of this License.
Introduction
*************
ClipTool is basically a storehouse for text you may want to paste into
other programs, perhaps multiple times.
Options
********
ClipTool understands the following icon tooltypes:
`CX_PRIORITY=PRIORITY'
lets you change the priority of ClipTool relative to other
Commodities Exchange programs. The default priority is 0. The
valid range is -128 to 127; the higher the number, the higher the
priority. This only changes the order in which the Commodities
gets to look at input events.
`CX_POPKEY=HOTKEY STRING'
specifies the key or keys that must be pressed to pop up ClipTool's
window. The default is `control lalt c'. Please refer to your
Workbench manual for a list of valid key combinations.
`CX_POPUP=yes|no'
determines whether the GUI window is opened when ClipTool is
launched. The default is `yes'. You will probably want to change
this if you put the program in the `WBStartup' drawer.
`EMBOSSED=yes|no'
Normally ClipTool will use embossed imagery to give its buttonbar
a 3-D look, unless it is run on a two colour screen. Setting
EMBOSSED=no forces ClipTool to always use its simpler 2-D imagery.
This may be useful if your colour preferences make the 3-D buttons
look strange.
`CREATEICONS=yes|no'
can be used to enable or suppress the creation of icons when data
is saved to a file. The default is to create icons. This can be
turned on and off at will.
`UNIT=0-255'
is the clipboard unit to use when ClipTool is launched. It can be
changed while the program is running. The default is 0.
`APPICON=yes|no'
determines whether ClipTool shall put an AppIcon, a dropbox, on the
Workbench. The default is `yes'.
`PORTNAME=AREXX PORT NAME'
is used to override the default port name, which is `CLIPTOOL'.
When started from the shell, ClipTool accepts arguments corresponding to
the icon tooltypes according to this AmigaDOS template:
CX_PRIORITY/K/N,CX_POPKEY/K,CX_POPUP/K,EMBOSSED/K,CREATEICONS/K,UNIT/K/N,APPICON/K,PORTNAME/K
The case and order of the keywords doesn't matter. The defaults are the
same as when used as tooltypes.
ARexx Interface
****************
ARexx Commands
===============
In this section, each ARexx command is explained following a standard
outline:
The format listing shows all the arguments and keywords accepted by the
command. Square brackets enclose arguments and keywords that are
optional. They are accepted by the command but are not required. A
vertical bar is used to separate options of which you may only choose
one.
In the command template, each argument is specified by a keyword (a
preset argument that the command understands) followed by a modifier
`/X' where `X' is one of the characters `A', `K', `N', or `S'. Each
keyword can have several of the modifiers. Neither the keywords nor the
modifiers are case-dependent.
This is followed by a description of the command.
OPEN
-----
Format: OPEN FILENAME FILE [DIR DIRECTORY]
Template: NAME=FILENAME/K/A,DIR/K
This command tries to open the file specified by the FILE argument,
load it, and make it the current buffer. It recognizes IFF FTXT files
automatically.
If you specify a relative pathname, ClipTool may not be able to locate
the file, because its current directory may differ from the current
directory of the process that sent the OPEN command. To overcome this
problem, you can use the DIR keyword to tell ClipTool to *temporarily*
change its current directory to DIRECTORY:
'open filename' foo 'dir' pragma('D')
The built-in ARexx function `pragma()', with the option `D', returns
the *full* path of the current directory.
The keyword NAME is provided as an alternative to the AUISG compliant
FILENAME.
SAVEAS
-------
Format: SAVEAS NAME FILE [FTXT] [DIR DIRECTORY]
Template: NAME/K/A,FTXT/S,DIR/K
This command saves the contents of the current buffer to the file
specified by the FILE argument. If the FTXT switch is used, it will be
saved as an IFF FTXT file.
If you specify a relative pathname, the result may not be what you
expect, because ClipTool's current directory may differ from the current
directory of the process that sent the SAVEAS command. To overcome this
problem, you can use the DIR keyword to tell ClipTool to *temporarily*
change its current directory to DIRECTORY (for a full example, *note
SaveClip.rexx::.):
'saveas name' foo 'dir' pragma('D')
The built-in ARexx function `pragma()', with the option `D', returns
the *full* path of the current directory.
SHOW
-----
Format: SHOW
Template: (none)
This command opens ClipTool's main window on the default public screen.
If it is already open, it is moved in front of the other windows on the
screen and made active.
SHOW is a synonym for the AUISG compliant command ACTIVATE.
HIDE
-----
Format: HIDE
Template: (none)
This command closes ClipTool's main window. It is not an error, if the
window is already closed.
HIDE is a synonym for the AUISG compliant command DEACTIVATE.
ACTIVATE
---------
Format: ACTIVATE
Template: (none)
This command opens ClipTool's main window on the default public screen.
If it is already open, it is moved in front of the other windows on the
screen and made active.
ACTIVATE is an AUISG compliant synonym for the SHOW command.
DEACTIVATE
-----------
Format: DEACTIVATE
Template: (none)
This command closes ClipTool's main window. It is not an error, if the
window is already closed.
DEACTIVATE is an AUISG compliant synonym for the HIDE command.
QUIT
-----
Format: QUIT
Template: (none)
This command stops ClipTool.
CUT
----
Format: CUT
Template: (none)
This command removes the current buffer and places it in the current
clipboard unit.
COPY
-----
Format: COPY
Template: (none)
This command places a duplicate of the current buffer into the current
clipboard unit.
PASTE
------
Format: PASTE
Template: (none)
This command puts the contents of the current clipboard unit into a new
buffer. This buffer is made the current buffer.
ERASE
------
Format: ERASE
Template: (none)
This command removes the current buffer.
PREVIOUS
---------
Format: PREVIOUS
Template: (none)
This command makes the previous buffer the current buffer.
NEXT
-----
Format: NEXT
Template: (none)
This command makes the next buffer the current buffer.
GETNUMBER
----------
Format: GETNUMBER VAR NAME
Template: VAR/K/A
Returns the number of clip buffers in the ARexx variable NAME.
GETCURRENT
-----------
Format: GETCURRENT VAR NAME
Template: VAR/K/A
Returns the number of the current buffer in the ARexx variable NAME.
CREATEICONS
------------
Format: CREATEICONS ON|OFF
Template: ON/S,OFF/S
This command controls the creation of icons when saving files. One of
the switches must be given.
GETCREATEICONS
---------------
Format: GETCREATEICONS VAR NAME
Template: VAR/K/A
Returns the current state of the `Create icons?' menu item in the ARexx
variable NAME. The state is one of two possible strings: `ON' or `OFF'.
Thus, the contents of NAME can be used as an argument to CREATEICONS
(*note CREATEICONS::.).
APPICON
--------
Format: APPICON ON|OFF
Template: ON/S,OFF/S
This command turns the AppIcon on and off.
GETUNIT
--------
Format: GETUNIT VAR NAME
Template: VAR/K/A
Returns the clipboard unit number in the ARexx variable NAME.
SETUNIT
--------
Format: SETUNIT NUMBER
Template: /N/A
This command sets the clipboard unit to NUMBER.
Examples
=========
This section contains a few example scripts, showing how you may control
ClipTool from ARexx.
LoadClip.rexx
--------------
/*
* loadclip - Load a file into the clipboard.
*/
parse arg fname
address cliptool
'open filename' fname 'dir' pragma(d)
'cut'
SaveClip.rexx
--------------
/*
* saveclip - Save the contents of the clipboard to a file.
*/
parse arg fname
address cliptool
'getnumber var before'
'paste'
'getnumber var after'
if before < after then do
'getcreateicons var state'
'createicons off' /* we don't want an icon */
'saveas name' fname 'dir' pragma('Directory')
'erase'
'createicons' state /* restore the previous state */
end
else say 'Clipboard is empty'
EDCopy.ed
----------
/*
* EDCopy - Copy the marked block to the current clipboard unit.
* Assumes ClipTool is running.
* You can add it to Ed's EDIT menu if you put
* the following command in S:Ed-startup:
*
* SI n 2 "Copy to Clipboard" "rx!EDCopy.ed!"
*
* where n is the menu item number.
*
* You can also add it to a key with something like
*
* SF n "rx!EDCopy.ed!"
*
* where n range from 1 to 57. Please refer to the Ed docs for details.
*/
