INSTALL: Installation instructions for XMLterm source code
----------------------------------------------------------
*NOTE* This is work in progress. User beware!
*NOTE* Check the XMLterm web site <http://xmlterm.org> for updates.
29 Nov 1999
In the following discussion, file and directory names are relative
to the main ("mozilla/extensions/xmlterm") directory. See the end of the
README file for a brief description of the subdirectories.
1. Source tree (skip this step if XMLterm is already in the source tree)
------------------------------------------------------------------------
The XMLterm source code is distributed as a tarball, xmlterm.tar.gz
This tar file needs to be untarred in the "mozilla/extensions" directory,
or any any other "mozilla/dir" directory one level below the top-level.
A subdirectory called "xmlterm" will be created there.
("mozilla" denotes the root directory of the Mozilla source tree)
If you have already untarred it elsewhere, simply move the "xmlterm" directory
to the right place.
2. Configuration
----------------
To recursively create all Makefiles from Makefile.in files, type the following:
makemake -r
The file "config/xmlterm_config.mk" contains XMLterm specific configuration
information that is needed in addition to any Mozilla configuration
information. It has already been hand-configured for Linux2.0/Linux2.2, and
Solaris2.6 platforms. It may need to be modified slightly to compile XMLterm
on other platforms.
At present XMLterm has been tested only on Linux (RedHat6.0) and Solaris2.6
platforms, using the M11 release as the base version of Mozilla.
XMLterm typically uses the UNIX pseudo-TTY interface to communicate with the
shell. At present, this interface is implemented only for Linux and Solaris
platforms.
XMLterm may compile on other Unix platforms, but it will use NSPR pipes,
rather than a pseudo-TTY, for process communication; this means that the
terminal control characters, such as Control-C for interrupting jobs, will not
work on those platforms. (See the file doc/PORTABILITY for a discussion of
portability issues)
3. Creating the dynamically loaded XPCOM/XPCONNECT component
------------------------------------------------------------
To create the dynamically loaded XPCOM library, type the following in the main
directory
make all
This creates the self-registering library "libxmlterm.so" and installs it in
the "mozilla/dist/bin/components" directory, along with some chrome
files. After this step, the following interfaces become accessible in Mozilla
through XPCOM/XPCONNECT:
mozIXMLTermShell (interface to XMLterm)
mozILineTerm (interface to the stand-alone LINETERM)
To clean up completely, type
make clean
4. Using the lightweight "xmlterm" stand-alone program
----------------------------------------------------
Step 3 creates an executable called "xmlterm" in the "mozilla/dist/bin"
directory. This is a lightweight program implementing XMLterm using the Gecko
layout engine only, without the added baggage of the full browser. Executing
"xmlterm" will create an XMLterm window. Click on this window to give it focus
before typing Unix commands.
The command line can be edited using EMACS-style key bindings.
Command completion should also work with TCSH and BASH, as should history
recall.
**NOTE**
The command prompt is assumed to be terminated by one of the characters
"#$%>?", followed by a space. If this is not the case, many features will not
work. This restriction will be relaxed in the future.
By default, blue coloring is used to indicate clickable display elements.
Note that the prompt and the input command line are clickable.
(Of course, the appearance of XMLterm is completely configurable
using the CSS stylesheet chrome://xmlterm/skin/default/xmlterm.css)
After typing one or two commands, click on the prompt string of any previous
command to see what happens! Then click again on the same prompt string.
Also click on "Hide all output" button at the top of the document.
Clicking on a previous command line (to the right of the prompt) re-executes
the command.
The sample Perl script "xls", the iconic/hypertext version of the Unix "ls"
command, is in the "tests" directory. Copy it to some directory in your path
to use it.
Note: At present, xmlterm only works with the GTK front end.
5. Creating an XMLterm window using the browser
-----------------------------------------------
At this time, XMLterm cannot be accessed through the menu bar. Instead, load
the URL "chrome://xmlterm/content/xmlterm.html" in the browser, either at the
command line or by typing it in the URL box. Then click on the browser window
with the mouse to shift focus and then start typing UNIX commands.
6. Stand-alone mode (optional)
------------------------------
Although XMLterm resides in the Mozilla source tree, portions of it are
capable of being compiled and linked completely independent of Mozilla. You
may want to do this for testing purposes. The "config" directory contains
make files that are used for this stand-alone mode. There is even a dumb
script called "makemake" which can be used to re-create make files, if the
corresponding Makefile.in files have been changed.
*NOTE* The executable "lterm" requires the NCURSES include file "curses.h"
To create the stand-alone executables, type
make STAND_ALONE=1 all
(To clean up stand-alone modules, type "make STAND_ALONE=1 clean")
This creates the stand-alone library in "base/lib" and some stand-alone
executables in the "linetest/lib" directory, in particular, one called
"lterm".
The executable "lterm" implements a line terminal (LINETERM), i.e., a
non-graphical version of XMLterm. In the future, this may be implemented using
NCURSES for full screen operation. At present, it only provides line-at-a-time
functionality and is used only for testing.
LINETERM acts as an "engine" for XMLterm, carrying out all the non-graphical
tasks, completely independent of Mozilla. It is written in C and is licensed
under both MPL and GPL. It provides functionality similar to the EMACS shell
mode or the GNU readline package.
LINETERM has various options where trace output may be redirected to a
different TTY device, for debugging purposes. LINETERM may be used like the
shell command "sh", e.g.,
prompt% lterm
prompt% ls
<listing>
prompt% exit
The "tests/escape" program can be used to generate terminal escape sequences
to test the XMLterm API. In particular, the following command enables
extensive trace output, if executed within an XMLterm or LINETERM:
tests/escape 1 98 D

xmlterm --- A graphical command line interface
==============================================
An early prototype of XMLterm, an XTERM-like terminal program implemented
using the open source Mozilla layout engine, is now available to tinker
with. XMLterm aims to add graphical and hypertext capabilities to the XTERM
command line interface, while maintaining backwards compatibility.
The basic design philosophy of XMLterm is that the user interface is a dynamic
XML document. The user and the computer interact by taking turns at appending
to this XML document. The plain text content of the XML document, i.e.,
excluding any markup, corresponds to the plain text that would be displayed by
a plain XTERM. The markup in the XML document is used to add graphical and
hypertext features. XMLterm uses the Mozilla layout engine to display the XML
document.
XMLterm is an open source project in its early stages. Comments and
contributions are welcome!
R. Saravanan <svn@xmlterm.org>
28 Nov 1999
===========
NOTES:
1. See the INSTALL file for configuration/installation instructions.
2. See the file doc/INSTALL.xmlterm for binary installation instructions.
3. Check the XMLterm web site <http://xmlterm.org> for updates.
===========================================================================
DOCUMENTATION
a. There is a README file in each directory that provides some basic
information.
b. The file "base/README" provides a brief overview of the XMLterm code
architecture.
c. The header files (*.idl, *.h) have comments describing class methods
and member variables in JAVADOC format. Look at them before delving
into the *.cpp files

XMLterm may be invoked one of two ways:
1. By loading the URL chrome://xmlterm/content/xmlterm.html in mozilla, or
2. By running the stand-alone executable "../geckoterm/xmlterm".
The diagram above shows the control-flow/layering hierarchy for both ways
of invoking XMLterm.
28 Nov 1999
===========================================================================
FILES:
The core source code for XMLterm in this directory consists of two distinct
families of files, those with names that begin with the prefix "moz" and all
the other files. The former are the Mozilla-specific portions of XMLterm,
written in C++. The remaining files constitute the Mozilla-independent portion
of XMLterm, referred to as "LineTerm".
============================================================================
LINETERM:
LineTerm is a line-oriented terminal program, in some respects similar in
functionality to the GNU Readline package. It is completely independent of the
Mozilla source code, is written in plain C, and dually licensed under GPL and
MPL.
============================================================================
INTERFACES:
lineterm.h Plain C interface to LineTerm
(used by mozLineTerm)
mozILineTerm.idl Scriptable XPCOM/XPCONNECT interface to LineTerm
(not used at the moment)
mozILineTermAux.h XPCOM interface to LineTerm, with extra features
(used by mozXMLTerminal)
mozIXMLTermShell.h Scriptable XPCOM/XPCONNECT interface to XMLterm
(used by the Javascript glue code in the XMLterm
start page at ../ui/content/xmlterm.html)
mozIXMLTerminal.h XPCOM interface to XMLterm
(used by mozXMLTermShell, ../geckoterm/mozGeckoterm)
mozIXMLTermStream.h XPCOM interface for displaying HTML/XML streams in
IFRAMES (used by mozXMLTermSession)
IMPLEMENTATIONS:
mozLineTerm.h/cpp Implementation of mozILineTerm, mozILineTermAux
Uses LineTerm to access shell
mozXMLTermShell.h/cpp Implementation of mozIXMLTermShell
Uses mozIXMLTerminal to create XMLterm
mozXMLTerminal.h/cpp Implementation of mozIXMLTerminal,
nsIDocumentLoaderObserver, and
nsIObserver
Uses mozILineTermAux to create LineTerm
Uses mozXMLTermListeners to capture user input
Uses mozXMLTermSession to display input/output
mozXMLTermListeners.h/cpp Implementations of nsIDOMKeyListener,
nsIDOMTextListener,
nsIDOMMouseListener,
nsIDOMDragListener
mozXMLTermStream.h/cpp Implementation of mozIXMLTermStream
CLASSES:
mozXMLTermSession.h/cpp Class to manage session input/output display
(used by mozXMLTerminal)
Uses mozIXMLTermStream to display streams
mozXMLTermUtils.h/cpp Abstract class for static utility functions
(for use by all classes)
============================================================================
The following are dually licensed under MPL and GPL:
LineTerm package:
lineterm.h Public interface to LineTerm
ltermPrivate.h Private common header file
ltermManager.c LineTerm manager
ltermIO.c Overlapping I/O functions
ltermInput.c Input handler
ltermOutput.c Output handler
ltermEscape.c Escape sequence handler
Low-level packages:
ptystream.h/c Stream-like interface to Unix pseudo-TTY
tracelog.h/c Simple tracing/logging diagnostic library
unistring.h/c Simple Unicode manipulation library

* Returns -1 if an error occurred while reading,
* -2 if pseudo-TTY has been closed,
* -3 if more than COUNT characters are present in the line
* (in this case the first COUNT characters are returned in BUF,
* and the rest are discarded).
* If the return value is -1, any further operations on the LTERM,
* other than LTERM_CLOSE, will always fail with an error return value.
* (If return value is -2, it means that the subordinate process has closed
* the pseudo-TTY. In this case, the LTERM still needs to be explicitly
* closed by calling LTERM_CLOSE for proper clean-up.)
*
* TIMEOUT is the number of platform-dependent time units
* (usually milliseconds on Unix) to wait to read data.
* A zero value implies no waiting.
* A negative TIMEOUT value implies infinite timeout, i.e., a blocking read.
* Non-zero values of TIMEOUT should be used only when the output thread
* is allowed to block.
*
* STYLE should be an array of same length as BUF, and contains
* the style bits associated with each character on return (see below).
*
* OPCODES contains a bit mask describing the type of output (see below).
* Using Extended Backus-Naur Form notation:
*
* OPCODES ::= STREAMDATA NEWLINE? COOKIESTR? XMLSTREAM? DOCSTREAM? WINSTREAM?
* if StreamMode data is being returned.
*
* OPCODES ::= SCREENDATA BELL? ( CLEAR
* | INSERT MOVEDOWN?
* | DELETE MOVEDOWN?
* | OUTPUT )
* if ScreenMode data is being returned.
*
* OPCODES ::= LINEDATA BELL? ( CLEAR
* | ( PROMPT | OUTPUT)? INPUT ( NEWLINE HIDE? )?
* | PROMPT? INPUT META ( COMPLETION | NEWLINE HIDE? )
* | OUTPUT NEWLINE? )
* if LineMode data is being returned.
*
* If OPCODES == 0, then it means that no data has been read.
*
* If the returned OPCODES has META and COMPLETION bits set, then the completed
* version of the meta input should be supplied through a call to
* LTERM_WRITE, with an input data type, as if the user had typed it.
*
* BUF_ROW and BUF_COL denote the row and starting column at which to
* display the data in BUF.
* (If character count returned by lterm_read is zero, implying there is no
* data in BUF, then values of BUF_ROW and BUF_COL should be ignored.)
* In ScreenMode or LineMode, CURSOR_ROW and CURSOR_COL denote the final
* cursor position after any data in BUF is displayed.
*
* The bottom left corner of the screen corresponds to row 0, column 0.
* BUF_COL, CURSOR_COL are always >= 0, with 0 denoting the leftmost column.
* (BUF_COL is always zero if NOPARTLINE flag is set for LTERM.)
* (CURRENT IMPLEMENTATION: BUF_COL is always zero.)
* BUF_ROW, CURSOR_ROW are always set to -1 when LTERM is in line mode,
* BUF_ROW, CURSOR_ROW are always >=0 when LTERM is in screen mode,
* with 0 denoting the bottom row.

"Finalize tree" to break XPCOM cycles and have clean shutdowns
--------------------------------------------------------------
XMLterm class embedding hierarchy
=================================

mozXMLTerminal
+-----------------+----------------+

mozXMLTermStream... (lineterm)
We would like to have clean shutdowns of an XMLterm, since we are using
external resources, e.g., a shell process or an rlogin process. However, the
XPCOM reference counting can hinder shutdowns, if there cycles. To avoid
that, the XMLterm interfaces have a Finalize or Close method. A shutdown
event triggers a call to the Finalize method of the root interface in the
"Finalize tree". When the Finalize method of any interface is called, it
first calls the Finalize methods of any child nodes in the Finalize tree, then
releases all the XPCOM references it owns, de-initializes itself and quietly
waits for its reference count to go to zero. In this "closed" state of the
interface, any attempts use it result in an error return.
The destructor of an object simply checks if all its interfaces have been
finalized, and calls the Finalize methods for any that have not been.

XMLterm installation instructions for Linux binaries
----------------------------------------------------
*NOTE* This work in progress. User beware!
*NOTE* Check the XMLterm web site <http://xmlterm.org> for updates.
19 Nov 1999
1. First obtain the Mozilla Linux binary tar file
ftp://ftp.mozilla.org/pub/mozilla/releases/m11/mozilla-i686-pc-linux-gnu-M11.tar.gz"
and untar it in any convenient location. This will create a
directory named "package" containing the binaries.
2. Untar the XMLterm binary tar file "xmlterm-i686-pc-linux-gnu-M11.tar.gz"
in the "package" directory created above.
3. Type the following command in the "package" directory:
./mozilla chrome://xmlterm/content/xmlterm.html
This should create an XMLTerm in the browser window. Then click on
that window with the mouse to shift focus and start typing UNIX
commands.
**NOTE**
The command prompt is assumed to be terminated by one of the characters
"#$%>?", followed by a space. If this is not the case, many features will
not work. This restriction will be relaxed in the future.
4. To use the stand-alone XMLterm executable called "xmlterm",
type the following command in the "package" directory:
./run-mozilla.sh xmlterm
(The Mozilla component registry may need to be updated by running the
full browser using step 3 at least once before running "xmlterm".)
5. The command line can be edited using EMACS-style key bindings.
Command completion should also work with TCSH and BASH, as should history
recall.
6. By default, blue coloring is used to indicate clickable display elements.
Note that the prompt and the input command line are clickable.
(Of course, the appearance of XMLterm is completely configurable
using the CSS stylesheet chrome://xmlterm/skin/default/xmlterm.css)
After typing one or two commands, click on the prompt string of any previous
command to see what happens! Then click again on the same prompt string.
Also click on "Hide all output" button at the top of the document.
Clicking on a previous command line (to the right of the prompt) re-executes
the command.
7. The sample Perl script "xls", the iconic/hypertext version of the Unix
"ls" command, is also installed in the "package" directory. Adding
the "package" directory to your path should enable you to use the "xls"
command.

Contributor with other software (except as part of the Contributor
Version) or other devices; or 4) under Patent Claims infringed by
Covered Code in the absence of Modifications made by that Contributor.
3. Distribution Obligations.
3.1. Application of License. The Modifications which You create
or to which You contribute are governed by the terms of this
License, including without limitation Section 2.2. The Source
Code version of Covered Code may be distributed only under the
terms of this License or a future version of this License
released under Section 6.1, and You must include a copy of this
License with every copy of the Source Code You distribute. You
may not offer or impose any terms on any Source Code version that
alters or restricts the applicable version of this License or the
recipients' rights hereunder. However, You may include an
additional document offering the additional rights described in
Section 3.5.
3.2. Availability of Source Code. Any Modification which You
create or to which You contribute must be made available in
Source Code form under the terms of this License either on the
same media as an Executable version or via an accepted Electronic
Distribution Mechanism to anyone to whom you made an Executable
version available; and if made available via Electronic
Distribution Mechanism, must remain available for at least twelve
(12) months after the date it initially became available, or at
least six (6) months after a subsequent version of that
particular Modification has been made available to such
recipients. You are responsible for ensuring that the Source Code
version remains available even if the Electronic Distribution
Mechanism is maintained by a third party.
3.3. Description of Modifications. You must cause all Covered
Code to which You contribute to contain a file documenting the
changes You made to create that Covered Code and the date of any
change. You must include a prominent statement that the
Modification is derived, directly or indirectly, from Original
Code provided by the Initial Developer and including the name of
the Initial Developer in (a) the Source Code, and (b) in any
notice in an Executable version or related documentation in which
You describe the origin or ownership of the Covered Code.
3.4. Intellectual Property Matters (a) Third Party Claims. If
Contributor has knowledge that a license under a third
party's intellectual property rights is required to exercise
the rights granted by such Contributor under Sections 2.1 or
2.2, Contributor must include a text file with the Source
Code distribution titled "LEGAL'' which describes the claim
and the party making the claim in sufficient detail that a
recipient will know whom to contact. If Contributor obtains
such knowledge after the Modification is made available as
described in Section 3.2, Contributor shall promptly modify
the LEGAL file in all copies Contributor makes available
thereafter and shall take other steps (such as notifying
appropriate mailing lists or newsgroups) reasonably
calculated to inform those who received the Covered Code
that new knowledge has been obtained.
(b) Contributor APIs. If Contributor's Modifications
include an application programming interface and Contributor
has knowledge of patent licenses which are reasonably
necessary to implement that API, Contributor must also
include this information in the LEGAL file.
(c) Representations. Contributor represents that,
except as disclosed pursuant to Section 3.4(a) above,
Contributor believes that Contributor's Modifications are
Contributor's original creation(s) and/or Contributor has
sufficient rights to grant the rights conveyed by this
License.
3.5. Required Notices. You must duplicate the notice in Exhibit
A in each file of the Source Code. If it is not possible to put
such notice in a particular Source Code file due to its
structure, then You must include such notice in a location (such
as a relevant directory) where a user would be likely to look for
such a notice. If You created one or more Modification(s) You
may add your name as a Contributor to the notice described in
Exhibit A. You must also duplicate this License in any
documentation for the Source Code where You describe recipients'
rights or ownership rights relating to Covered Code. You may
choose to offer, and to charge a fee for, warranty, support,
indemnity or liability obligations to one or more recipients of
Covered Code. However, You may do so only on Your own behalf,
and not on behalf of the Initial Developer or any
Contributor. You must make it absolutely clear than any such
warranty, support, indemnity or liability obligation is offered
by You alone, and You hereby agree to indemnify the Initial
Developer and every Contributor for any liability incurred by the
Initial Developer or such Contributor as a result of warranty,
support, indemnity or liability terms You offer.
3.6. Distribution of Executable Versions. You may distribute
Covered Code in Executable form only if the requirements of
Section 3.1-3.5 have been met for that Covered Code, and if You
include a notice stating that the Source Code version of the
Covered Code is available under the terms of this License,
including a description of how and where You have fulfilled the
obligations of Section 3.2. The notice must be conspicuously
included in any notice in an Executable version, related
documentation or collateral in which You describe recipients'
rights relating to the Covered Code. You may distribute the
Executable version of Covered Code or ownership rights under a
license of Your choice, which may contain terms different from
this License, provided that You are in compliance with the terms
of this License and that the license for the Executable version
does not attempt to limit or alter the recipient's rights in the
Source Code version from the rights set forth in this License. If
You distribute the Executable version under a different license
You must make it absolutely clear that any terms which differ
from this License are offered by You alone, not by the Initial
Developer or any Contributor. You hereby agree to indemnify the
Initial Developer and every Contributor for any liability
incurred by the Initial Developer or such Contributor as a result
of any such terms You offer.
3.7. Larger Works. You may create a Larger Work by combining
Covered Code with other code not governed by the terms of this
License and distribute the Larger Work as a single product. In
such a case, You must make sure the requirements of this License
are fulfilled for the Covered Code.
4. Inability to Comply Due to Statute or Regulation.
If it is impossible for You to comply with any of the terms of
this License with respect to some or all of the Covered Code due
to statute, judicial order, or regulation then You must: (a)
comply with the terms of this License to the maximum extent
possible; and (b) describe the limitations and the code they
affect. Such description must be included in the LEGAL file
described in Section 3.4 and must be included with all
distributions of the Source Code. Except to the extent
prohibited by statute or regulation, such description must be
sufficiently detailed for a recipient of ordinary skill to be
able to understand it.
5. Application of this License.
This License applies to code to which the Initial Developer has
attached the notice in Exhibit A and to related Covered Code.
6. Versions of the License.
6.1. New Versions. Netscape Communications Corporation
(''Netscape'') may publish revised and/or new versions of the
License from time to time. Each version will be given a
distinguishing version number.
6.2. Effect of New Versions. Once Covered Code has been
published under a particular version of the License, You may
always continue to use it under the terms of that version. You
may also choose to use such Covered Code under the terms of any
subsequent version of the License published by Netscape. No one
other than Netscape has the right to modify the terms applicable
to Covered Code created under this License.
6.3. Derivative Works. If You create or use a modified version
of this License (which you may only do in order to apply it to
code which is not already Covered Code governed by this License),
You must (a) rename Your license so that the phrases ''Mozilla'',
''MOZILLAPL'', ''MOZPL'', ''Netscape'', "MPL", ''NPL'' or any
confusingly similar phrase do not appear in your license (except
to note that your license differs from this License) and (b)
otherwise make it clear that Your version of the license contains
terms which differ from the Mozilla Public License and Netscape
Public License. (Filling in the name of the Initial Developer,
Original Code or Contributor in the notice described in Exhibit A
shall not of themselves be deemed to be modifications of this
License.)
7. DISCLAIMER OF WARRANTY.
COVERED CODE IS PROVIDED UNDER THIS LICENSE ON AN "AS IS'' BASIS,
WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED,
INCLUDING, WITHOUT LIMITATION, WARRANTIES THAT THE COVERED CODE
IS FREE OF DEFECTS, MERCHANTABLE, FIT FOR A PARTICULAR PURPOSE OR
NON-INFRINGING. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE
OF THE COVERED CODE IS WITH YOU. SHOULD ANY COVERED CODE PROVE
DEFECTIVE IN ANY RESPECT, YOU (NOT THE INITIAL DEVELOPER OR ANY
OTHER CONTRIBUTOR) ASSUME THE COST OF ANY NECESSARY SERVICING,
REPAIR OR CORRECTION. THIS DISCLAIMER OF WARRANTY CONSTITUTES AN
ESSENTIAL PART OF THIS LICENSE. NO USE OF ANY COVERED CODE IS
AUTHORIZED HEREUNDER EXCEPT UNDER THIS DISCLAIMER.
8. TERMINATION.
8.1. This License and the rights granted hereunder will
terminate automatically if You fail to comply with terms herein
and fail to cure such breach within 30 days of becoming aware of
the breach. All sublicenses to the Covered Code which are
properly granted shall survive any termination of this
License. Provisions which, by their nature, must remain in effect
beyond the termination of this License shall survive.
8.2. If You initiate litigation by asserting a patent
infringement claim (excluding declatory judgment actions) against
Initial Developer or a Contributor (the Initial Developer or
Contributor against whom You file such action is referred to as
"Participant") alleging that:
(a) such Participant's Contributor Version directly or indirectly
infringes any patent, then any and all rights granted by such
Participant to You under Sections 2.1 and/or 2.2 of this License
shall, upon 60 days notice from Participant terminate
prospectively, unless if within 60 days after receipt of notice
You either: (i) agree in writing to pay Participant a mutually
agreeable reasonable royalty for Your past and future use of
Modifications made by such Participant, or (ii) withdraw Your
litigation claim with respect to the Contributor Version against
such Participant. If within 60 days of notice, a reasonable
royalty and payment arrangement are not mutually agreed upon in
writing by the parties or the litigation claim is not withdrawn,
the rights granted by Participant to You under Sections 2.1
and/or 2.2 automatically terminate at the expiration of the 60
day notice period specified above.
(b) any software, hardware, or device, other than such
Participant's Contributor Version, directly or indirectly
infringes any patent, then any rights granted to You by such
Participant under Sections 2.1(b) and 2.2(b) are revoked
effective as of the date You first made, used, sold, distributed,
or had made, Modifications made by that Participant.
8.3. If You assert a patent infringement claim against
Participant alleging that such Participant's Contributor Version
directly or indirectly infringes any patent where such claim is
resolved (such as by license or settlement) prior to the
initiation of patent infringement litigation, then the reasonable
value of the licenses granted by such Participant under Sections
2.1 or 2.2 shall be taken into account in determining the amount
or value of any payment or license.
8.4. In the event of termination under Sections 8.1 or 8.2
above, all end user license agreements (excluding distributors
and resellers) which have been validly granted by You or any
distributor hereunder prior to termination shall survive
termination.
9. LIMITATION OF LIABILITY.
UNDER NO CIRCUMSTANCES AND UNDER NO LEGAL THEORY, WHETHER TORT
(INCLUDING NEGLIGENCE), CONTRACT, OR OTHERWISE, SHALL YOU, THE
INITIAL DEVELOPER, ANY OTHER CONTRIBUTOR, OR ANY DISTRIBUTOR OF
COVERED CODE, OR ANY SUPPLIER OF ANY OF SUCH PARTIES, BE LIABLE
TO ANY PERSON FOR ANY INDIRECT, SPECIAL, INCIDENTAL, OR
CONSEQUENTIAL DAMAGES OF ANY CHARACTER INCLUDING, WITHOUT
LIMITATION, DAMAGES FOR LOSS OF GOODWILL, WORK STOPPAGE, COMPUTER
FAILURE OR MALFUNCTION, OR ANY AND ALL OTHER COMMERCIAL DAMAGES
OR LOSSES, EVEN IF SUCH PARTY SHALL HAVE BEEN INFORMED OF THE
POSSIBILITY OF SUCH DAMAGES. THIS LIMITATION OF LIABILITY SHALL
NOT APPLY TO LIABILITY FOR DEATH OR PERSONAL INJURY RESULTING
FROM SUCH PARTY'S NEGLIGENCE TO THE EXTENT APPLICABLE LAW
PROHIBITS SUCH LIMITATION. SOME JURISDICTIONS DO NOT ALLOW THE
EXCLUSION OR LIMITATION OF INCIDENTAL OR CONSEQUENTIAL DAMAGES,
SO THIS EXCLUSION AND LIMITATION MAY NOT APPLY TO YOU.
10. U.S. GOVERNMENT END USERS.
The Covered Code is a ''commercial item,'' as that term is
defined in 48 C.F.R. 2.101 (Oct. 1995), consisting of
''commercial computer software'' and ''commercial computer
software documentation,'' as such terms are used in 48
C.F.R. 12.212 (Sept. 1995). Consistent with 48 C.F.R. 12.212 and
48 C.F.R. 227.7202-1 through 227.7202-4 (June 1995), all
U.S. Government End Users acquire Covered Code with only those
rights set forth herein.
11. MISCELLANEOUS.
This License represents the complete agreement concerning subject
matter hereof. If any provision of this License is held to be
unenforceable, such provision shall be reformed only to the
extent necessary to make it enforceable. This License shall be
governed by California law provisions (except to the extent
applicable law, if any, provides otherwise), excluding its
conflict-of-law provisions. With respect to disputes in which at
least one party is a citizen of, or an entity chartered or
registered to do business in the United States of America, any
litigation relating to this License shall be subject to the
jurisdiction of the Federal Courts of the Northern District of
California, with venue lying in Santa Clara County, California,
with the losing party responsible for costs, including without
limitation, court costs and reasonable attorneys' fees and
expenses. The application of the United Nations Convention on
Contracts for the International Sale of Goods is expressly
excluded. Any law or regulation which provides that the language
of a contract shall be construed against the drafter shall not
apply to this License.
12. RESPONSIBILITY FOR CLAIMS.
As between Initial Developer and the Contributors, each party is
responsible for claims and damages arising, directly or
indirectly, out of its utilization of rights under this License
and You agree to work with Initial Developer and Contributors to
distribute such responsibility on an equitable basis. Nothing
herein is intended or shall be deemed to constitute any admission
of liability.
13. MULTIPLE-LICENSED CODE.
Initial Developer may designate portions of the Covered Code as
?Multiple-Licensed?. ?Multiple-Licensed? means that the Initial
Developer permits you to utilize portions of the Covered Code
under Your choice of the NPL or the alternative licenses, if any,
specified by the Initial Developer in the file described in
Exhibit A.

Portability issues
---------------------
16 Sep 1999
Much of the XMLterm code is cross-platform. Implementation features that
affect portability at the moment are:
1. Main event handling:
By default, the present implementation of XMLterm directly uses a GTK
call to set up a handler for XMLterm output events. This can be disabled
by setting NO_CALLBACK=1 in the make command line, and calling the
method mozIXMLTermShell::Poll() frequently to poll for readable output
from LineTerm.
(A better event/callback mechanism needs to be implemented.)
2. pseudo-TTY (PTY) operations:
The PTY interface for XMLterm is currently implemented only for
two platforms, Linux and Solaris. At some point, the PTY interface
should be ported to most Unix platforms. On platforms where PTY
operations are not implemented, the cross-platform NSPR process mechanism
is used to create a "slave" process. However, this process uses NSPR
pipes for communication, which prevents the use of terminal control
characters such as the most usefule Control-C. (Is there a way around
this restriction?)
What about Windows? It should be possible to use XMLterm even under Windows,
using the NSPR process/pipe functions for communication and
using the Cygwin utilities to simulate the Unix environment.
3. The lightweight GeckoTerm uses GTK.
4. The "unistring" module uses wchar functions which do not always have
the same names.

doc --- Some implementation notes and documentation
This directory contains some rudimentary documentation and notes.
See the README file in the "base" directory (../base/README) for a brief
overview of XMLterm code architecture
For a discussion of XMLterm from the user's point of view, check the XMLterm
home page at <http://xmlterm.org>.
Eventually, an XMLterm project page at mozilla.org
<http://www.mozilla.org/projects/not-ready-yet/> will contain a description

12 Sep 1999
Appending each output line separately, separated by <BR> elements, to a
displayed HTML document seems to be rather slow. See the file
base/mozXMLTermSession.cpp
As a workaround, multiple output lines are batched into a single <PRE>
element. This will basically only work for plain text output, without markup.
To disable this workaround and expose the "bug", create the XMLterm libraries
as described in the INSTALL file. Then execute the following to make the
"buggy" libraries:
cd base
rm mozXMLTermSession.o
make NO_WORKAROUND=1 mozXMLTermSession.o
make libs
(If you are using the "gterm" executable, you will need to re-make it as
well)
Now execute any command which produces several lines of output in an
XMLterm window.
