XeTeX "hangs"

XeTeX "hangs"

[Mojca Miklavec]

[-- Attachment #1: Type: text/plain, Size: 499 bytes --]

If I try to compile the folllowing code with XeTeX, it "hangs" (as if
it was waiting for further input):

\catcode`ð=\active \defð{^^f0} % only hangs for "F0", other numbers are OK
\starttext
ð
\stoptext

I didn't manage to test the same example with "plain" XeTeX (tetex is
a bit misconfigured since the standalone ConTeXt is installed), but
Jonathan says that it runs OK on his computer. Is my system broken
again or are some other black forces working anywhere?

Thanks,
    Mojca

Hi Mojca,

Trying your minimal file on my Mac OS X, with XeConTeXt or with plain  
XeTeX, I observe the same hanging...

However, the following, taken out of an example sent to you by  
Jonathan K., works fine with both (indeed commenting out \starttext  
and \stoptext in plain XeTeX):

\starttext
\font\lmec = ec-lmr10 at 36 pt

\lmec
Testing... ð

Testing... ^^F0

\catcode`č=\active \defč{^^a3}
\catcode`š=\active \defš{^^b2}
\catcode`ž=\active \defž{^^ba}

Testing... čšž

\stoptext

while the following results in a PDF file with "Testing... ° 0"

\starttext
\catcode`ð=\active \defð{^^F0}

Testing... ð

\stoptext

Needless to tell you that all this seems extremely obscure to me...

Best regards: OK

Hi Hans,

This file:
%% eth-hans-1.tex
\starttext
what do you get when you run that with \tracingall

Testing... ð

\catcode`ð=\active \defð{^^F0}
\tracingall

Testing... ð

and what does

%\show ð

return? and what

Testing... ðaaa

Hans

\stoptext
%% end eth-hans-1.tex

typeset with XeConTeXt gives a PDF where again one has "Testing... ð"  
in the first occurence, and then "Testing... ° 0", and the process  
takes some 41 seconds...


If the above file is typeset with ConTeXt alone it stops with the  
error message:

! Missing number, treated as zero.

                    ∞
l.9 \catcode`√∞
                =\active \def√∞{^^F0}
?
Process aborted

If the line \show ð is uncommented in the above file, then XeConTeXt  
stops with this error message:

[]\*12ptrmtf* and what does

making posters with ContexT

[batela]

Hi

I am trying to making a scientifique poster in Context. I need some 
suggestions,
foreground an example, to start. Somebody has a nice example to share?
What is the correct scales for the fonts?

Have a nice day/night

Thanks to all

Jorge

Hi,

I always start tasks like that by setting the paper size and switching
\showframe ;). About the font size: the poster should be readable from 1.5
meter distance. It's good to start from at least 24 pt. You surely realise
that you have to be extremely concise in your texts, so you may end up at
something like 21 pt (which is suboptimal but acceptable).

Attached you find an example (figures not included). Feel free to modify
it, share and enjoy.

> Jorge

BTW, we'd appreciate if you used your real name in the From: header.

Have a nice towel day,
D.A.

\chapter{Introduction}

Personal Computer (PC) as a router is
\startitemize
\item Reliable and highly functional
\item Comparable to middle-class routers (e.g., CISCO~7500)
\stopitemize
But\dots
\startitemize
\item Configurable with difficulties (via \type{/etc} files)
\item Limited mainly by PCI system bus (up to 2~Gbps with 64bit/66MHz bus)
\stopitemize

The goal of the \externalfigure[liberouter][height=0.5\baselineskip]{}
project: IPv6 router solving
those limitations. How?
\startitemize
\item Hardware accelerator {\em Combo6}
\item XML based configuration system {\em Netopeer}
\stopitemize

\chapter{Router Architecture}

Combo6 is a PCI card containing FPGA, memories (SSRAMs and DRAM), expansion
connectors, and supporting logic. Network interfaces are mounted on an
expansion daughter card for interfaces to be changed easily.

\startlinecorrection
\midaligned{\externalfigure[combo6][height=12\baselineskip]}
\stoplinecorrection

Design rules (just pure instance of {\em hardware/software codesign}
principles):
\startitemize
\item Packet switching and filtering will be performed by Combo6
\item PC can do the rest; routing path calculations, configuration,
statistics computation
\item Communication through PCI is limited to configuration, routing table
updates, statistics collection, and exception handling
\item Usual Operating System tools can be used, like \type{ifconfig} and
routing daemons
\stopitemize

\chapter{Packet Processing in Hardware}

Key idea: Packet processing in FPGA is done by a chain of dedicated
processors with simple, specialized instruction sets designed for their
particular purposes. We call them {\em nanoprocessors}---they are
interpreted by FPGA's microcode. Instruction sets are \quotation{between
FSMs and RISC processors.}

\startitemize
\item Changing nanoprograms in runtime is possible (with no need of VHDL
compilation)---this differs from Partial Reconfiguration
\item VHDL tools are not needed to change nanoprograms, our free
development environment can be employed
\item New features can be added step-by-step
\item On the contrary, Partial Reconfiguration may produce more efficient
designs
\stopitemize

Packet processing is pipelined. A packet flows through the FPGA and
memories. An incoming packet is received by the Input Packet Buffer and
passed to the Header Field Extractor. The HFE pushes the body of the packet
into the dynamic memory. Meanwhile, it parses its headers and creates a
{\em Unified-header} and a structure reflecting actual arrangement of the
headers. The Unified-header is a fixed structure containing information
relevant for routing and filtering decisions.

The Lookup Processor (LUP) processes the Unified-header performing a lookup
nanoprogram. The lookup nanoprogram is kept in CAM and SRAM. Using CAM is
fast, unfortunately, IPv6 requires nearly 600~bits to check. Widest
available CAMs have less than 300~bits, therefore a combination of CAM
search and lookup instructions (conditional jumps) is used.

\startlinecorrection
\midaligned{\externalfigure[combo.1][height=8\baselineskip]}
\stoplinecorrection

Packet Replicator and Block of Output Queues (RQU) replicates the packet ID
to queues computed by LUP. Output Packet Editor modifies headers of the
packet before it is sent out. Operating system is one of the output
interfaces. It allows to deliver packets to the host computer as well as
handling packets hardware is not able to process.

\chapter{Software Support}

Software drivers are developed for NetBSD (and FreeBSD) and ported to
Linux. Driver operations include FPGA chip configuration, accessing
memories in the card, and hardware/software interface operations.

Other part of router software {\em hides presence of Combo6 in the host
computer}. The card should perform the same routing and filtering
functionality as the host computer itself, only faster. Host computer uses
routing table, configuration of interfaces, and firewall setting, Combo6
has to run the LUP nanoprocessor just once to make a decision how to handle
a packet.

To be able to combine routing table and firewall setting into one lookup
operation, we developed a concept of {\em routing/firewalling
table}---firewall rules are applied on routing table rows a-priori.

\chapter{Netopeer Configuration System}

PC based routers are running under various operating systems with various
configuration files causing problems to network administrators. To
overcome this we are working on a unified configuration environment {\em
Netopeer}. The primary configuration is kept in an XML repository. User
interfaces implement Command Line Interface, web interface, and SNMP.
Configurations for several operating systems and commercial routers can be
generated from the XML, also allowing to convert among the representations.

Hi Hans,

Typesetting the following with XeConTeXt:

%% eth-hans-2.tex
\starttext

Testing... ð

\bgroup
\let\unicodechar\unicodenumber
\catcode`ð=\active \defð{^^F0}
\egroup

Testing... ð
\stoptext

gives what is intended, that is a PDF with twice "Testing... ð".
However the above cannot be typeset with ConTeXt alone, since an  
error is diagnosed saying

! Missing number, treated as zero.
<to be read again>
                    ∞
l.11 \catcode`√∞
                 =\active \def√∞{^^F0}
?

Best regards: OK

i need a bit more info:

= the file eth-hans2.tex (zipped!)

= how you call it, yopu say that it works ok with xecontext, so what do 
you mean with 'context alone'

ok, what you see happen in 'non xetex context' is ok,

\catcode`ð=\active \defð{^^F0}

will fail because pdftex is *not* utf and only sees 8 bit characters, so 
you can only set the catcodes 0-255

\catcode `<number>=<number>

and in your case `Ã will become a number ° but ° not

\bgroup
\let\unicodechar\unicodenumber
\catcodeð=\active \defð{^^F0}
\egroup

could work (watch out: no `) but again, \catcode<16 bit number> is not 
accepted by regular 8 bit tex

so, a the moment, what you observe is ok; at the end of this year, in a 
32 bit pdftex, things may work different

That's true for pdftex, but XeTeX should handle them OK (assuming that
you're using the proper encoding in your file). If you change ^^f0 to
^^f1 or whatever other number, it works without any problems. It's
just ^^f0 that's causing problems for some weird reason. I don't know
if this is XeTeX or ConTeX bug (or the wrong usage perhaps, but it was
Jonathat who sent this example, only for other letters).

Hans, in what encoding are you sending/using this? Seems like UTF-8
file opened as if it was "latin1" (might be the same).

You should use utf-8-encoded "eth" literally, not two different character
   \catcode`ð=\active \defð{^^f0}  ð
