What is xcb? |
| 3 |
|
|
============ |
| 4 |
|
|
Do you ever wish you could cut two or more separate pieces of text |
| 5 |
|
|
at once from a window? Do you ever need to save the output from one |
| 6 |
|
|
command for reuse in several subsequent tasks? Do you ever find |
| 7 |
|
|
yourself wanting some easy means of globally exporting data, e.g. |
| 8 |
|
|
to a parent shell, to another xterm or application, or to another |
| 9 |
|
|
machine or user? If you answer yes to any of these questions, then |
| 10 |
|
|
xcb is for you. |
| 11 |
|
|
|
| 12 |
|
|
Xcb provides access to the cut buffers built into every X server. |
| 13 |
|
|
It allows the buffers to be manipulated either via the command line, |
| 14 |
|
|
or with the mouse in a point and click manner. The buffers can be |
| 15 |
|
|
used as holding pens to store and retrieve arbitrary data fragments, |
| 16 |
|
|
so any number of different pieces of data can be saved and recalled later. |
| 17 |
|
|
The program is designed primarily for use with textual data. |

What is so good about this release? |
| 21 |
|
|
=================================== |
| 22 |
|
|
Release 2.3i add I18n and Unicode support to the base xcb. It also |
| 23 |
|
|
supports more formats, so applications requiring compound text |
| 24 |
|
|
for example work. You cna also paste utf-8 and japanese text... |
| 25 |
|
|
|
| 26 |
|
|
Release 2.3 fixes a bug found in the XView code that prevented data |
| 27 |
|
|
from being pasted from xcb to XView applications such as cmdtool. |
| 28 |
|
|
|
| 29 |
|
|
The release also adds a Motif GUI, selectable as a compile-time option. |
| 30 |
|
|
Now you can choose between the Athena or the Motif look and feel. |
| 31 |
|
|
|
| 32 |
|
|
|
| 33 |
|
|
Yes, but has it been ported to WHIZ-IX 12.1A.00x, on SRS-80 27-bit CPUs? |

Xcb has been written to compile using both ANSI and non-ANSI compilers. |
| 61 |
|
|
It is in use in X11 R3, R4, R5 and R6 environments. The current version |
| 62 |
|
|
uses either the Athena widgets (libXaw.a) or the Motif widgets (libXm.a), |
| 63 |
|
|
plus the X Toolkit library (libXt.a). |
| 64 |
|
|
|
| 65 |
|
|
|
| 66 |
|
|
Ok, where is it available? |
| 67 |
|
|
========================== |
| 68 |
|
|
|
| 69 |
|
|
This version is a branch of the original xcb sources. It's homepage can be |
| 70 |
|
|
found at http://xcb.plan9.de/ |
| 71 |
|
|
|
| 72 |
|
|
|
| 73 |
|
|
So, it will compile, will it? |
| 74 |
|
|
============================= |
| 75 |
|
|
Yes! The makefiles will, by default, build the Athena widgets version |
| 76 |
|
|
of xcb. If you prefer Motif, you should adjust the $(GUI) definition |
| 77 |
|
|
to be -DMOTIF. In addition, if you wish to cut and paste text between |
| 78 |
|
|
xcb and XView applications, you should also add the -DXVIEW flag. |
| 79 |
|
|
|
| 80 |
|
|
AT&T SVR4 sites need libnsl.a during linking. If you are using |
| 81 |
|
|
SVR4, and you don't like Imakefiles, you will need to add -lnsl to the |
| 82 |
|
|
LIBS in Makefile.std. |
| 83 |
|
|
|
| 84 |
|
|
HP-UX users may find that the Athena widgets are not installed on their |
| 85 |
|
|
machine, even though the components are freely available as part of the |
| 86 |
|
|
MIT X11 distribution. There is an HP maintained, but unsupported, set |
| 87 |
|
|
of X11R4 libraries and utilities (including the Athena widgets) for the |
| 88 |
|
|
HP 9000 Series 300, 400, 700, and 800. You can get the libraries, |
| 89 |
|
|
include files, and config files (imake) via anonymous FTP from |
| 90 |
|
|
hpcvaaz.cv.hp.com (15.255.72.15) - look for pub/MitX11R4/libs.s*00.tar.Z |
| 91 |
|
|
|
| 92 |
|
|
AIX 3.2 users may find their Athena components are installed in a |
| 93 |
|
|
non-standard place. Check the directory /usr/lpp/X11/Xamples/lib/Xaw. |
| 94 |
|
|
|
| 95 |
|
|
VMS and ULTRIX users may find their Athena components are installed in |
| 96 |
|
|
a non-standard place too. Check the directory /usr/include/mit for the |
| 97 |
|
|
Athena include files. |
| 98 |
|
|
|
| 99 |
|
|
|
| 100 |
|
|
And how do I set the thing up? |
| 101 |
|
|
============================== |
| 102 |
|
|
That is pretty easy too. Once you have compiled the program, |
| 103 |
|
|
you can start using it straight away - just put it in your favourite |
| 104 |
|
|
bin directory. The program contains a minimal set of fallback resources |
| 105 |
|
|
so that it will behave itself even if there are no X resource specifications |
| 106 |
|
|
for it to feed on. To install the program, plus its application defaults |
| 107 |
|
|
file, and the man page, simply type 'make install install.man', after |
| 108 |
|
|
checking the target directories for the install in the Imakefile/Makefile.std. |
| 109 |
|
|
|
| 110 |
|
|
|
| 111 |
|
|
Who is to blame? Where do I send complaints? |
| 112 |
|
|
============================================= |
| 113 |
|
|
Blame me. If you have any bug reports, porting problems, comments, |
| 114 |
|
|
more comments, suggestions, patches, unwanted cash etc. please tell me. |

I couldn't reach the original author, who wrote most of xcb, but your |
| 123 |
|
|
mileage may vary. Xcb was originally brought to you by: |
| 124 |
|
|
|
| 125 |
|
|
Better still, if you really like xcb, send me a postcard! |
| 126 |
|
|
(to P.O. Box 213, Belgrave, Victoria, Australia. 3160). |

Enjoy. |
