Example: Sorting in LuaTeX
by Jonathan Sauer 09 Aug '07

09 Aug '07

Hello, yesterday I experimented a little with \directlua, and I decided to code a sorting routine, since sorting in TeX (as i.e. implemented in the experimental LaTeX 3 code or in Bernd Raichle's paper "Sorting in TeX's mouth") is quite slow. The example is in PlainTeX. ------------------------------------- CUT ----------------------------------- % We `preload' the necessary functions into the Lua state % % Note that comments inside \directlua must be TeX comments (``%''); % Lua comments (``--'') do not work % % The sorting code has been copied from the Lua users wiki (page % ``MakingLuaLikePhp'') \directlua0{ function explode(str,div) if (div=='') then return false end local pos,arr = 0,{} % For each divider found for st,sp in function() return string.find(str,div,pos,true) end do % Attach chars left of current divider table.insert(arr,string.sub(str,pos,st-1)) % Jump past current divider pos = sp + 1 end % Attach chars right of last divider table.insert(arr,string.sub(str,pos)) return arr end function implode(t,div) return table.concat(t,div) end } % #1 = continuation (called with the sorted list as its only % parameter), #2 = delimiter, #3 = <delimiter>-separated list \def\sort#1#2#3{% \directlua0{% % We prevent expansion and then escape all characters special % to lua in the parameters. This is necessary to prevent them % from (a) executed right now and (b) being misunderstood by % Lua. % % We convert the string into a table, delimited by a % (unexpanded, escaped) delimiter: local t = explode("\luaescapestring{\unexpanded{#3}}", "\luaescapestring{\unexpanded{#2}}") % We sort the table in-place: table.sort(t) % We output the table as a string. % % We use a single call to tex.print to prevent spaces in % the output, since all tex.print calls except the last add % an \endlinechar (LuaTeX manual 4.1.10.1): tex.print("\luaescapestring{\unexpanded{#1}}{" .. implode(t," ") .. "}") }% } % Output tokens without expansion \def\typeout#1{\message{\unexpanded{[#1]}}} % Example (text taken from Wikipedia, ``Hyperreality'') \sort{\typeout}{ }{% In semiotics and postmodern philosophy, the term hyperreality characterizes the inability of consciousness to distinguish reality from fantasy, especially \in technologically advanced postmodern cultures. Hyperreality is a means of characterising the way consciousness defines what is actually `real' in a world where a multitude of media can radically shape and filter the original event or experience being depicted. Some famous theorists of hyperreality include Jean Baudrillard, \Albert Borgmann, Daniel Boorstin, and Umberto Eco. % Most aspects of hyperreality can be thought of as `reality by proxy.' For example, a viewer watching pornography begins to live in the non-existent world of the pornography, and even though the pornography is not an accurate depiction \of sex, for the viewer, the reality of `sex' becomes something non-existent. Some examples are simpler: the McDonald's `M' arches create a world with the promise of endless amounts of identical food, when in `reality' the `M' represents nothing, and the food produced is neither identical nor infinite. % Baudrillard in particular suggests that the world we live in has been replaced by a copy world, \where we seek simulated stimuli and nothing more. Baudrillard borrows, from Jorge Luis Borges (which Borges also borrowed from Lewis Carroll), the example of a society whose cartographers create a map so detailed that it covers the very things it was designed to \represent. When the empire declines, the map fades into the landscape and there is neither the representation nor the real remaining -- just the hyperreal. % Baudrillard's idea of \hyperreality was heavily influenced by phenomenology, semiotics, and Marshall McLuhan.} \bye ------------------------------------- CUT ----------------------------------- Sorting in Lua is really, really fast, even though the token list has to be converted into a table and back. At least, it is a lot faster than sorting in TeX. Caveat: In TeX, braces can be used to hide the <delimiter>; this is not possible in the above code. I plan to code a "string.findOutsideBraces" function to handle braces correctly, but I wonder if this should not be a library routine. In any case: Imagine the possibilities when using Lua not only for manipulating the node list, but also for parsing user input! Delighted, Jonathan

Comments in \directlua
by Jonathan Sauer 09 Aug '07

09 Aug '07

Hello, while experimenting with \directlua, I noticed that Lua comments ('--') do not work as one would expect, i.e.: \directlua{ function hello() -- Just say hello tex.print("Hello world) end } This results in the error message "end expected at <eof>". Why? Because TeX (most of the time) converts line endings into spaces, to above code is a single line as far as Lua is concerned: \directlua{function hello() -- Just say hello tex.print("Hello world) end} So Lua comment should not be used inside \directlua. TeX comments of course do work. This behaviour is puzzling at first, but then just as expected. Still, I think a note describing this should be in the manual. Jonathan

Pattern memory?
by Arthur Reutenauer 08 Aug '07

08 Aug '07

Hello, When I try to compile the recent Mark IV formats I get the following error: ! TeX capacity exceeded, sorry [pattern memory=80000]. and I don't know which setting it is in texmf.cnf (no pattern_memory, and no variable equal to 80000 either). This problem had already been reported to me by Yannis as he tried to compile the LaTeX format at the end of June. Where should I look for that? Arthur

LuaTeX roadmap
by Simon Spiegel 08 Aug '07

08 Aug '07

I think the roadmap on luatex.org is wrong, it says: "The first formal release will be at TUG 2009 in Cork (Ireland)". AFAIK TUG 2008 will be in Cork. Just a small thing, but I thought I should report it. simon -- Simon Spiegel Steinhaldenstr. 50 8002 Zürich Telephon: ++41 44 451 5334 Mobophon: ++41 76 459 60 39 http://www.simifilm.ch "Was soll aus mir mal werden, wenn ich mal nicht mehr bin?"

HZ in beta 0.10.1
by Jonathan Sauer 08 Aug '07

08 Aug '07

Hello, feeling adventurous, I tried to typeset a document of mine using the LuaTeX beta 0.10.1. The document makes use of the HZ features of pdfTeX. I remembered a message from Taco (from 02 Mar 2007, to be precise), that HZ should work again, so I decided to give it a try. The resulting PDF is interesting. Fonts are switched seemingly at random, text overlaps and runs into the margin (even though there are no overfull boxes). Very artistic ;-) I created a Plain-based minimum example to test only font expansion, not protrusion. Then I discovered some weird behaviour when typesetting paragraphs, even when not using font expansion: ------------------------------------- CUT --------------------------------- \pdfoutput1 % Without the next two lines, the fonts are ok. With only the first % or only the second line, the fonts are ok as well. With both lines, % most of the time \tentt is used, even when \tenrm is set % % Perhaps one expanded font overwrites the other? \pdffontexpand\tenrm 30 10 10 autoexpand\relax \pdffontexpand\tentt 30 10 10 autoexpand\relax % Does not matter if this is 1 or 2: \pdfadjustspacing2 \baselineskip13.6pt \tenrm % In the following text, the fonts are quite messed up: Hello {\tentt world} with Lua\TeX. Hello {\tentt world} with Lua\TeX. Hello {\tentt world} with Lua\TeX. Hello {\tentt world} with Lua\TeX. Hello {\tentt world} with Lua\TeX. Hello {\tentt world} with Lua\TeX. Hello {\tentt world} with Lua\TeX. Hello {\tentt world} with Lua\TeX. % The following text is typeset in a narrow column and cut off at the % left. This also happens when font expansion is turned off (but not % in pdfTeX 1.40.3). This is just {\tentt test}. Just a {\tentt test}. Nothing more than a {\tentt test}. Just a {\tentt test}. Nothing more than a {\tentt test}. Just a {\tentt test}. Nothing more than a {\tentt test}. Just a {\tentt test}. Nothing more than a {\tentt test}. Just a {\tentt test}. Nothing more than a {\tentt test}. Just a {\tentt test}. Nothing more than a {\tentt test}. % The following text is typeset in a narrow column as well: This is just test. Just a test. Nothing more than a test. Just a test. Nothing more than a test. Just a test. Nothing more than a test. Just a test. Nothing more than a test. Just a test. Nothing more than a test. Just a test. Nothing more than a test. % The following *was* typeset across the whole page, until I added % the `-- not' et cetera: Some more text, just to check if the weird typesetting of the last paragraph can be repeated. Still, it would be strange if not. But it looks like -- not, at least if the paragraph is short. If it is longer, the text is typeset incorrectly. % The following is typeset across the whole page, just like it should % be: But only if the paragraph is a little bit longer, a few lines. \bye ------------------------------------- CUT --------------------------------- The corresponding log file: ------------------------------------- CUT --------------------------------- This is luaTeX, Version 3.141592-beta-0.10.1-2007071919 (Web2C 7.5.6) (format=luatex 2007.8.4) 7 AUG 2007 20:25 **FontExpandTest (FontExpandTest.tex pdfTeX warning (font expansion): font should be expanded before its first use pdfTeX warning (font expansion): font should be expanded before its first use Overfull \hbox (11721.41785pt too wide) in paragraph at lines 26--32 [][]\tentt (-10) This is just test.
