the real time editing feature
by Marius 25 Sep '10

25 Sep '10

Hello, While working with ConTeXt and other TeXes I miss the real time editing feature, it is very time consuming to write formulas, tables, position images, format text and after every change recompile. So, after some google, I found the BaKoMa TeX. It's very impressive how fast it is. The author on his page [1] writes: "The reason of this scalability is that only one page of document is reformatted at editing document." [1] http://www.bakoma-tex.com/menu/texword.php So, the question is: how does he do that with latex? Or how to recompile just one page of a document with ConTeXt? As I am not very competent with internals of ConTeXt, I can't imagine how to do that. With a very simple scenario my guess is: context --pipe 1) input preamble, 2) input text up to the page X, generate pdf and wait for user input, 3) if user edits page X, input text from page X and update pdf replacing page X. The problem with this algorithm is that a complete pdf document is produced just after the \stoptext command is input, but atfter this command the pipe is closed too. The other problem is that I don't now how to implement with ConTeXt commands the part of the step 3: "update pdf replacing page X". Maybe you have answers to these questions or a better solution to this problem. Marius

Bug: English versions of manuals mention Dutch command
by Sietse Brouwer 12 Sep '10

12 Sep '10

Dear ConTeXt-devs, The English-language versions of "ConTeXt, the manual" (http://www.pragma-ade.com/general/manuals/cont-eni.pdf) and "ConTeXt, an excursion" (http://www.pragma-ade.com/general/manuals/ms-cb-en.pdf) both contain mentions of \inmarge, which should be \inmargin. This slipped through the net when ConTeXt was translated from Dutch to English, I expect. In the manual, \inmarge is found on PDF pages 364 and 64 (numbered 361 and 61, respectively). In the excursion, \inmarge is found on PDF pages 33 and 63, 64 (which are numbered 31, 61, and 62). Kind regards, and many thanks for working on ConTeXt, Sietse Brouwer Who is learning ConTeXt, and likes it a lot so far.

cont-en.xml
by Wolfgang Schuster 12 Sep '10

12 Sep '10

Hi, i plan to update cont-en.xml with changes in mkiv (new keys and commands) but i'm unsure if it's good to mix mkii and mkiv. I think it's to make a separate definition file for mkiv which contains the extra keys for the commands (e.g. sectionsegments for \setuphead) and use the current one for mkii only. Wolfgang

Luatex 0.63.0 announcement
by Taco Hoekwater 09 Sep '10

09 Sep '10

Hi, I have just uploaded the archives for a new luatex release, 0.63.0. This is a development release. News: * Drop tex.ht[], tex.wd[], tex.dp[]. * Drop OCP support (and associated primitives). * Add tex.catcode[], tex.lccode[], tex.sfcode[], tex.uccode[], tex.mathcode[] and tex.delcode[] and associated functions. * Add CIDset tables to the output pdf where appropriate. * Added a 'string' field to late_lua nodes on the lua side. This field does not convert the assigned string to a tokenlist. * The result of fontloader.open() now has some virtual accessors (as well as fontloader.to_table). * There is now a `short reference' in the manual folder (functionref.pdf) Bugfixes: * Fix a crash on an empty font (bugreport #468). * Fix a crash for extremely long pattern arguments. * Fix a crash on bad virtual character arguments in lua. * Fix hyphenation exceptions. * Prevent linebreak between initial local_par paragraph whatsit and a following skip (bugreport #437). * Fix placement of scripts on textstyle big operators in MATH fonts (bugreport #466). * Fix a crash on the return value of MPlib's 'postscript' operation on images. * Fix a crash on \leftghost & \rightghost in math mode. The archives can be downloaded from supelec as usual: http://foundry.supelec.fr/gf/project/luatex/ You could also check out the sources via anonymous svn: svn co http://foundry.supelec.fr/svn/luatex/tags/beta-0.63.0 Bugs and feature requests can be added to the issue tracker at http://tracker.luatex.org Have fun, Taco

Luatex 0.62.0 announcement
by Taco Hoekwater 23 Aug '10

23 Aug '10

Hi, I have just uploaded the archives for a new luatex release, 0.62.0. This is a development release, but it also fixes some nasty bugs in beta 0.61.0, so if you use that right now, upgrading is recommended. News: * LuaTeX now uses libpoppler (0.12.4) instead of xpdf. * All backend functions now report what file they were searching for whenever a file cannot be found. * Input-ed lua files are now mentioned in the fls file if the --recorder switch is specified on the command line. * Paragraph indentation hlist nodes and hlist and vlist nodes generated by alignment rows and cells now have a subtype (3 for indent box, 4 for rows/columns, 5 for cells). * The 'epdf' lib is in active development and still growing. * The 'fontforge' table is finally removed (was deprecated since 0.40). Bugfixes: * A new mplib import fixes two bad bugs in mplib: - string equality test was wrong - type declarations could delete pre-existing variables * PNG images with transparency could create random size differences in the generated PDF. * In some special cases, font expansion could cause wrong spacing in the generated PDF. * \letterspacefont was broken since a very long time. * The node subtype of the \leftskip and \rightskip glues was wrong. * Some memory leaks have been removed. * Various manual fixes. The archives can be downloaded from supelec as usual: http://foundry.supelec.fr/gf/project/luatex/ You could also check out the sources via anonymous svn: svn co http://foundry.supelec.fr/svn/luatex/tags/beta-0.62.0 Bugs and feature requests can be added to the issue tracker at http://tracker.luatex.org Have fun, Taco

by Taco Hoekwater 28 Jul '10

28 Jul '10

Hi, I have just uploaded the archives for a new luatex release, 0.61.0, the first of the betas toward 0.70.0. New features: * New lua library 'epdf' for introspection of PDF inclusions, see the manual for details. * Mplib version 1.502 is now included (which is still beta, so be careful). * new "finish_pdffile" and "pre_dump" callbacks. * new function pdf.pageref() * In the lua 'tex' library: assignment to internal glue parameters is now allowed. * New lua function tex.error(). Bugfixes: * Fix for crashes on fonts with bad Panose values. * Fix for a box placement bug that could sometimes cause text to overlap. * Fix for a few small PDF/A1-a compatibility bugs. * Fix \letterspacefont. * Fix \Ustopdisplaymath in combination with aligned displays. * In math delimiters, the last of a chain of predefined sizes was always ignored if there were also extensible parts. The archives can be downloaded from supelec as usual: http://foundry.supelec.fr/gf/project/luatex/ You could also check out the sources via anonymous svn: svn co http://foundry.supelec.fr/svn/luatex/tags/beta-0.61.0 Bugs and feature requests can be added to the issue tracker at http://tracker.luatex.org Have fun, Taco

MetaPost 1.502 (beta version)
by Taco Hoekwater 27 Jul '10

27 Jul '10

I am happy to announce a new beta release of MetaPost: ---------------------------------------------------------------------- MetaPost 1.502 ---------------------------------------------------------------------- The standalone distribution package and a win32 binary can be downloaded immediately from http://foundry.supelec.fr/gf/project/metapost/ This is a beta release following the major internal rewrite done for 1.500. After quite a lot of community feedback on the previous two releases (a big thank you! goes to the testers) most of the bugs should be gone now, but just in case: please be careful and check the output of this metapost version when it is used in production work. The win32 binary is intended for texlive or a similar web2c-based installation, this executable will *not* work for miktex. Of course, we welcome any comments (either good or bad) that you may have. Simply replying to this message is fine, but see the bottom of the message for a more formal way to report bugs and feature requests. ---------------------------------------------------------------------- What is new in MetaPost version 1.502: ---------------------------------------------------------------------- * New build system and kpathsea imported from TeX Live. * Many small bugfixes to 1.501. ---------------------------------------------------------------------- What is new in MetaPost version 1.501: ---------------------------------------------------------------------- * The maximum number of variable instances has increased from approx. 33 million (2^25-1) to 2 billion (2^31-1). * New build system and kpathsea imported from TeX Live. * Many small bugfixes to 1.500. ---------------------------------------------------------------------- What is new in MetaPost version 1.500: ---------------------------------------------------------------------- * Actual memory dump files do not exist any more. --mem=<MEM> and all other methods of supplying a MEM file are now interpreted somewhat like this pseudo-metapost-code: begingroup; let dump = end; input MEM[.mp]; endgroup; this process is supposed to be transparent besides the facto that there is some extra terminal output and logging. * All memory is now allocated and freed dynamically. There are only two remaining overflow errors(1): "expansion depth" : this is a guard against infinite recursion, the value is 10000. "sizes per font" : this is maxed out for data-structure reasons, the value is 32767. from texmf.cnf, now only the "error_line", "half_error_line" and "print_line settings" are used. (1) but now you can reach the operating system limits, of course. * As this is an alpha release containing lots and lots of new code, MetaPost starts up with the internal equivalent of 'loggingall;' in effect. This results in log files that can help in debugging. * Expect bugs and (minor) memory leaks. ---------------------------------------------------------------------- Legal notice / license / bug reports ---------------------------------------------------------------------- MetaPost is a system for producing graphics developed by John Hobby at AT&T, based on Donald Knuth's Metafont.
