GNU GENERAL PUBLIC LICENSE
|
||||
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.
|
||||
|
||||
GNU GENERAL PUBLIC LICENSE
|
||||
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
|
||||
|
||||
0. 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.
|
||||
|
||||
1. 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.
|
||||
|
||||
2. 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 1
|
||||
above, provided that you also meet all of these conditions:
|
||||
|
||||
a) You must cause the modified files to carry prominent notices
|
||||
stating that you changed the files and the date of any change.
|
||||
|
||||
b) 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.
|
||||
|
||||
c) 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.
|
||||
|
||||
3. You may copy and distribute the Program (or a work based on it,
|
||||
under Section 2) in object code or executable form under the terms of
|
||||
Sections 1 and 2 above provided that you also do one of the following:
|
||||
|
||||
a) Accompany it with the complete corresponding machine-readable
|
||||
source code, which must be distributed under the terms of Sections
|
||||
1 and 2 above on a medium customarily used for software interchange; or,
|
||||
|
||||
b) 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 1 and 2 above on a medium
|
||||
customarily used for software interchange; or,
|
||||
|
||||
c) 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 Subsection b above.)
|
||||
|
||||
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.
|
||||
|
||||
4. 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.
|
||||
|
||||
5. 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.
|
||||
|
||||
6. 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.
|
||||
|
||||
7. 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.
|
||||
|
||||
8. 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.
|
||||
|
||||
9. 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.
|
||||
|
||||
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.
|
||||
|
||||
10. 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
|
||||
|
||||
11. 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.
|
||||
|
||||
12. 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 is 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.

||||
|
||||
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.

dialog - Display dialog boxes in shell script (version 0.3)
|
||||
===========================================================
|
||||
|
||||
This is a program that will enable you to present a variety of questions or
|
||||
display messages using dialog boxes from a shell script. Currently, these
|
||||
types of dialog boxes are implemented: yes/no box, menu box, input box,
|
||||
message box, text box, info box, checklist box. The idea of writing this
|
||||
program came from the fact that most questions asked in a shell script (and
|
||||
many interactive programs as well) can be classified into these few types:
|
||||
|
||||
|
||||
1) One that requires the user to answer either yes or no.
|
||||
|
||||
2) One that presents a number of options for the user to choose.
|
||||
|
||||
3) One that requires the user to input a string.
|
||||
|
||||
4) One that displays a message and optionally wait for a key press
|
||||
before continuing.
|
||||
|
||||
5) One that presents a list of options that can be turned on or off.
|
||||
|
||||
|
||||
The program 'dialog' can, say for example, be called in a shell script to
|
||||
present the first type of questions like this:
|
||||
|
||||
|
||||
if dialog --yesno <question text> <height> <width>
|
||||
then
|
||||
...
|
||||
fi
|
||||
|
||||
|
||||
e.g. if dialog --yesno "Do you want to continue?" 7 51
|
||||
then
|
||||
echo "Continuing..."
|
||||
else
|
||||
echo "Aborting..."
|
||||
fi
|
||||
|
||||
|
||||
I've included a sample shell script for each type of boxes in the directory
|
||||
samples. The program requires ncurses to compile. Running 'dialog' without
|
||||
arguments will display the usage.
|
||||
|
||||
|
||||
|
||||
FEATURES
|
||||
--------
|
||||
|
||||
* Friendly dialog box interface with buttons, etc.
|
||||
|
||||
* Auto wrap around of question text if it's too long to fit on
|
||||
one line.
|
||||
|
||||
* "\n" can be inserted in question text to control line breaking
|
||||
explicitly. The real newline character '\n' can also be used.
|
||||
|
||||
* run-time configruation of color settings and other options using
|
||||
a configuration file.
|
||||
|
||||
|
||||
|
||||
WHAT'S NEW SINCE VERSION 0.21?
|
||||
------------------------------
|
||||
|
||||
* some changes for faster screen update.
|
||||
|
||||
* much more flexible color settings. Can use all 16 colors
|
||||
(8 normal, 8 highlight) of the Linux console.
|
||||
|
||||
* added run-time configuration using configuration file.
|
||||
|
||||
* some minor bug fixes and cleanups for menubox, checklist and
|
||||
textbox.
|
||||
|
||||
* added a man page.
|
||||
|
||||
* some changes for easier porting to other Unix systems (tested
|
||||
on Ultrix, SunOS and HPUX)
|
||||
|
||||
|
||||
|
||||
INSTALLATION
|
||||
------------
|
||||
|
||||
1. cd ./src
|
||||
|
||||
2. Go to step 3 if your system has ncurses (e.g. Linux).
|
||||
Edit Makefile and remove -DHAVE_NCURSES from DEFS. Also
|
||||
remove rc.c from SRCS and rc.o from OBJS. Change LIBS as
|
||||
appropriate (Usually, it should be '-lcurses -ltermcap').
|
||||
Go to step 6.
|
||||
|
||||
3. Edit Makefile and remove -DBROKEN_WSCRL from DEFS if you
|
||||
are using ncurses 1.8.3 or newer. Menu scrolling should
|
||||
be faster. DON'T REMOVE IT IF YOU ARE NOT USING AT LEAST
|
||||
VERSION 1.8.3 OF NCURSES.
|
||||
|
||||
4. Edit dialog.h and change USE_SHADOW to FALSE if you don't
|
||||
want shadowed dialog boxes. Also change USE_COLORS to
|
||||
FALSE if you don't want colors. Note that 'dialog' will
|
||||
check if the terminal supports colors, and will use mono
|
||||
settings if it doesn't, so USE_COLORS won't do any harm
|
||||
even if you have a mono display. Also note that USE_SHADOW
|
||||
implies USE_COLORS. These two options can be changed at
|
||||
run-time using the run-time configuration file (see below).
|
||||
|
||||
5. Edit colors.h to change default color definitions if you
|
||||
don't like the defaults. These are only compiled in defaults,
|
||||
you can change them at run-time using the run-time
|
||||
configuration file.
|
||||
|
||||
6. 'make depend; make install' will compile and install the
|
||||
binaries in /usr/local/bin (change BINDIR in Makefile if
|
||||
you want to install elsewhere).
|
||||
|
||||
7. 'make install.man' will install the man page to
|
||||
/usr/local/man (change MANDIR in Makefile if you want to
|
||||
install elsewhere).
|
||||
|
||||
8. You can then try the sample shell scripts in the samples
|
||||
directory (make sure the environment variable DIALOG is
|
||||
not set, the scripts use it to find the dialog binary, if
|
||||
it's not set, "../src/dialog" will be used).
|
||||
|
||||
9. Don't forget to mail me (mail address at end of this file)
|
||||
if you find any bugs, have some good color settings to
|
||||
contribute or just want to tell me that you like it, Don't
|
||||
mail me if you don't like it :-)
|
||||
|
||||
|
||||
|
||||
RUN-TIME CONFIGURATION
|
||||
----------------------
|
||||
|
||||
1. Create a sample configuration file by typing:
|
||||
|
||||
"dialog --create-rc <file>"
|
||||
|
||||
2. At start, 'dialog' determines the settings to use as follows:
|
||||
|
||||
a) if environment variable DIALOGRC is set, it's value
|
||||
determines the name of the configuration file.
|
||||
|
||||
b) if the file in (a) can't be found, use the file
|
||||
$HOME/.dialogrc as the configuration file.
|
||||
|
||||
c) if the file in (b) can't be found, use compiled in
|
||||
defaults.
|
||||
|
||||
3. Edit the sample configuration file and copy it to some place
|
||||
that 'dialog' can find, as stated in step 2 above.
|
||||
|
||||
|
||||
|
||||
|
||||
Comments and bug reports welcome.

Hi, this is a text dialog box. It can be used to display text from a file.
|
||||
The file should not contain any 'tab' characters, so you should 'expand'
|
||||
the file first if it contains 'tab' characters.
|
||||
|
||||
It's like a simple text file viewer, with these keys implemented:
|
||||
|
||||
PGDN/SPACE - Move down one page
|
||||
PGUP/'b' - Move up one page
|
||||
DOWN/'j' - Move down one line
|
||||
UP/'k' - Move up one line
|
||||
LEFT/'h' - Scroll left
|
||||
RIGHT/'l' - Scroll right
|
||||
'0' - Move to beginning of line
|
||||
HOME/'g' - Move to beginning of file
|
||||
END/'G' - Move to end of file
|
||||
'/' - Forward search
|
||||
'?' - Backward search
|
||||
'n' - Repeat last search (forward)
|
||||
'N' - Repeat last search (backward)

|
||||
.SH DESCRIPTION
|
||||
.B Dialog
|
||||
is a program that will let you to present a variety of questions or
|
||||
display messages using dialog boxes from a shell script. Currently,
|
||||
these types of dialog boxes are implemented:
|
||||
.LP
|
||||
.BR yes/no " box," " menu" " box," " input" " box,"
|
||||
.BR message " box," " text" " box," " info" " box, and"
|
||||
.BR checklist " box."
|
||||
.SH OPTIONS
|
||||
.TP
|
||||
.B \-\-clear
|
||||
The screen will be cleared to the
|
||||
.BR "screen attribute" " on exit."
|
||||
.TP
|
||||
.BI \-\-create-rc " file"
|
||||
.RB "Since " dialog " supports run-time configuration,"
|
||||
this can be used to dump a sample configuration file to the file specified
|
||||
by
|
||||
.IR file "."
|
||||
.TP
|
||||
.BI \-\-title " title"
|
||||
Specifies a
|
||||
.I title
|
||||
string to be displayed at the top of the dialog box.
|
||||
.TP
|
||||
.B Box Options
|
||||
.TP
|
||||
.BI \-\-yesno " text height width"
|
||||
.RB A " yes/no" " dialog box of size"
|
||||
.I height
|
||||
rows by
|
||||
.I width
|
||||
columns will be displayed. The string specified by
|
||||
.I text
|
||||
is displayed inside the dialog box. If this string is too long to be fitted
|
||||
in one line, it will be automatically divided into multiple lines at
|
||||
appropriate places. The
|
||||
.I text
|
||||
string may also contain the sub-string
|
||||
.I
|
||||
"\en"
|
||||
or newline characters
|
||||
.I `\en\'
|
||||
to control line breaking explicitly. This dialog box is useful for
|
||||
asking questions that require the user to answer either yes or no.
|
||||
.RB "The dialog box has a" " Yes" " button and a " No
|
||||
button, in which the user can switch between by pressing the
|
||||
.IR TAB " key."
|
||||
.TP
|
||||
.BI \-\-msgbox " text height width"
|
||||
.RB A " message" " box is very similar to a" " yes/no" " box."
|
||||
The only difference between a
|
||||
.B message
|
||||
box and a
|
||||
.B yes/no
|
||||
box is that a
|
||||
.B message
|
||||
box has only a single
|
||||
.B OK
|
||||
button. You can use this dialog box to display any message you like.
|
||||
After reading the message, the user can press the
|
||||
.I ENTER
|
||||
key so that
|
||||
.B dialog
|
||||
will exit and the calling shell script can continue its operation.
|
||||
.TP
|
||||
.BI \-\-infobox " text height width"
|
||||
.RB An " info" " box is basically a" " message" " box."
|
||||
However, in this case,
|
||||
.B dialog
|
||||
will exit immediately after displaying the message to the user. The
|
||||
screen is not cleared when
|
||||
.B dialog
|
||||
exits, so that the message will remain on the screen until the calling
|
||||
shell script clears it later. This is useful when you want to inform
|
||||
the user that some operations are carrying on that may require some
|
||||
time to finish.
|
||||
.TP
|
||||
.BI \-\-inputbox " text height width"
|
||||
.RB "An " input " box is useful when you want to ask questions that"
|
||||
require the user to input a string as the answer. When inputing the
|
||||
string, the
|
||||
.I BACKSPACE
|
||||
key can be used to correct typing errors. If the input string is longer than
|
||||
can be fitted in the dialog box, the input field will be scrolled. On exit,
|
||||
the input string will be printed on
|
||||
.IR stderr "."
|
||||
.TP
|
||||
.BI \-\-textbox " file height width"
|
||||
.RB A " text" " box lets you display the contents of a text file in a"
|
||||
dialog box. It is like a simple text file viewer. The user can move
|
||||
through the file by using the
|
||||
.IR UP/DOWN ", " PGUP/PGDN
|
||||
.RI and " HOME/END" " keys available on most keyboards."
|
||||
If the lines are too long to be displayed in the box, the
|
||||
.I LEFT/RIGHT
|
||||
keys can be used to scroll the text region horizontally. For more
|
||||
convenience, forward and backward searching functions are also provided.
|
||||
.IP "\fB\-\-menu \fItext height width menu-height \fR[ \fItag item \fR] \fI..."
|
||||
As its name suggests, a
|
||||
.B menu
|
||||
box is a dialog box that can be used to present a list of choices in
|
||||
the form of a menu for the user to choose. Each menu entry consists of a
|
||||
.IR tag " string and an " item " string. The"
|
||||
.I tag
|
||||
gives the entry a name to distinguish it from the other entries in the
|
||||
menu. The
|
||||
.I item
|
||||
is a short description of the option that the entry represents. The
|
||||
user can move between the menu entries by pressing the
|
||||
.I UP/DOWN
|
||||
keys, the first letter of the
|
||||
.I tag
|
||||
as a hot-key, or the number keys
|
||||
.IR 1-9 ". There are"
|
||||
.I menu-height
|
||||
entries displayed in the menu at one time, but the menu will be
|
||||
scrolled if there are more entries than that. When
|
||||
.B dialog
|
||||
exits, the
|
||||
.I tag
|
||||
of the chosen menu entry will be printed on
|
||||
.IR stderr "."
|
||||
.IP "\fB\-\-checklist \fItext height width list-height \fR[ \fItag item status \fR] \fI..."
|
||||
.RB "A " checklist " box is similar to a " menu " box in that there are"
|
||||
multiple entries presented in the form of a menu. Instead of choosing
|
||||
one entry among the entries, each entry can be turned on or off by the
|
||||
user. The initial on/off state of each entry is specified by
|
||||
.IR status "."
|
||||
On exit, a list of the
|
||||
.I tag
|
||||
strings of those entries that are turned on will be printed on
|
||||
.IR stderr "."

|
||||
*
|
||||
* HISTORY:
|
||||
*
|
||||
* 17/12/93 - Version 0.1 released.
|
||||
*
|
||||
* 19/12/93 - menu will now scroll if there are more items than can fit
|
||||
* on the screen.
|
||||
* - added 'checklist', a dialog box with a list of options that
|
||||
* can be turned on or off. A list of options that are on is
|
||||
* returned on exit.
|
||||
*
|
||||
* 20/12/93 - Version 0.15 released.
|
||||
*
|
||||
* 29/12/93 - Incorporated patch from Patrick J. Volkerding
|
||||
* (volkerdi@mhd1.moorhead.msus.edu) that made these changes:
|
||||
* - increased MAX_LEN to 2048
|
||||
* - added 'infobox', equivalent to a message box without pausing
|
||||
* - added option '--clear' that will clear the screen
|
||||
* - Explicit line breaking when printing prompt text can be
|
||||
* invoked by real newline '\n' besides the string "\n"
|
||||
* - an optional parameter '--title <string>' can be used to
|
||||
* specify a title string for the dialog box
|
||||
*
|
||||
* 03/01/94 - added 'textbox', a dialog box for displaying text from a file.
|
||||
* - Version 0.2 released.
|
||||
*
|
||||
* 04/01/94 - some fixes and improvements for 'textbox':
|
||||
* - fixed a bug that will cause a segmentation violation when a
|
||||
* line is longer than MAX_LEN characters. Lines will now be
|
||||
* truncated if they are longer than MAX_LEN characters.
|
||||
* - removed wrefresh() from print_line(). This will increase
|
||||
* efficiency of print_page() which calls print_line().
|
||||
* - display current position in the form of percentage into file.
|
||||
* - Version 0.21 released.
|
||||
*
|
||||
* 05/01/94 - some changes for faster screen update.
|
||||
*
|
||||
* 07/01/94 - much more flexible color settings. Can use all 16 colors
|
||||
* (8 normal, 8 highlight) of the Linux console.
|
||||
*
|
||||
* 08/01/94 - added run-time configuration using configuration file.
|
||||
*
|
||||
* 09/01/94 - some minor bug fixes and cleanups for menubox, checklist and
|
||||
* textbox.
|
||||
*
|
||||
* 11/01/94 - added a man page.
|
||||
*
|
||||
* 13/01/94 - some changes for easier porting to other Unix systems (tested
|
||||
* on Ultrix, SunOS and HPUX)
|
||||
* - Version 0.3 released.
|
||||
*
|
||||
* 08/06/94 - Patches by Stuart Herbert - S.Herbert@shef.ac.uk
|
||||
* Fixed attr_clear and the textbox stuff to work with ncurses 1.8.5
|
||||
* Fixed the wordwrap routine - it'll actually wrap properly now
|
||||
* Added a more 3D look to everything - having your own rc file could
|
||||
* prove 'interesting' to say the least :-)
|
||||
* Added radiolist option
|
||||
* - Version 0.4 released.
