Luatex 0.45.0 announcement
by Taco Hoekwater 18 Nov '09

18 Nov '09

Hi, I have just uploaded the archives for a new luatex release, 0.45.0. New features: * Loading big OTF fonts via lua is now much faster than before, at the expense of a bit of precision loss in the calculated bounding boxes. * Two new token lists are provided: \pdfxformresources and \pdfxformattr, as an alternative to \pdfxform keywords. * \input and \openin now accept braced filenames. * The \endlinechar can now be set to any value between 0 and 127. * Luatex can now optionally use kpathsea to find lua require() files. * The new primitives \aligntab and \alignmark are aliases for the use of & and # in alignments. * \pdfrefximage [width <dimen>] [height <dimen>] [depth <dimen>] <imageref> overrules settings from \pdfximage for this \pdfrefximage call only * The print precision for small numbers in lua code (tostring) has been improved. * Akira Kakuto suppled a patch that restricts writing to files with names such as latex.bat etc. (on windows only) * (un-feature): from now on luatex now only handles 4 direction specifiers: TLT (latin), TRT (arabic), RTT (cjk), and LTL (mongolian). The other directions now generate an error. * (un-feature): xpdf's automatic lower- and uppercasing retry attempts for nonfound image pdf files has been removed. * The callbacks hpack_filter, vpack_filter and pre_output_filter pass on an extra string argument for the direction, when known (nil == use default). * The lua functions node.hpack(), node.vpack() and node.dimensions() now accept an optional direction argument (not given == use default). * \pdfrefxform [width <dimen>] [height <dimen>] [depth <dimen>] <formref> scales a form object; similar principle as with \pdfximage: depth alone doesn't scale, it shifts vertically. * A change to the relative ordering inside font name discovery for use by the backend: now it tries <f>.psname first, as that is much less likely to contain spaces. * For ttc fonts, now the used subfont name and its index id are printed to the terminal, and if the backend cannot find a ttc subfont, the run is aborted. Bug fixes: * Prevent crashes for lua-loaded fonts without a (tfm) name. * Remove spurious newlines in the output pdf that could be the result of using \pdfximage for an included pdf figure too early. * Full font embedding for wide otf and ttf fonts now really works (older versions only pretended that it did work). * node.dimensions() sometimes continued past the 'stop' node. * Images inside virtual fonts were broken. * The processing of \language=-1 was wrong, resulting in hyphenation attempts even though there was no proper language set up. * Fix for finding files in --output-directory. * Fix for handling of --file-line-error. * tex.box[] assignments are now checked to make sure the assigned node has the right id (hlist or vlist). * show_node_list (as in \showbox) produced spurious local_par whatsit prints in the output after direction nodes. * The handling of pdf literals has been sped up. 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-0.45.0 Bugs and feature requests can be added to the issue tracker at http://tracker.luatex.org Have fun, Taco

numbers formatting
by Paweł Jackowski 15 Nov '09

15 Nov '09

Folks, last changes to number formatting in luatex makes things somewhat confusing. Please consider the following. \directlua{ local floor = math.floor local round = function(n) return floor(10000*n+0.5)/10000 end n = math.pi % generic round doesn't work anymore, print() io.write(round(n)) % but explicit conversion to string helps print() io.write(round(n).."") % now lets take more pleasant n n = 100.4 % now the explicit conversion to string doesn't help either print() print(round(n)) % same with pdf.print, tex.write pdf.print(round(n)) tex.write(round(n)) }?\end This is hardly controlable, as the same operations gives completelly different results for n=10.4 and n=100.4. Obviously much depends on internal representation of the number, but one never had to bother before. The reason I'm concerned is that string.format() function allows only fixed decimal digits "%.<n>f" or fixed all the digits "%.<n>g". And what is actually needed in most cases is "round to <n> digits and omit extra zeros at the end". That is why I tend to use floor(scale*n+0.5)/scale for rounding, which is not a good solution any longer. Can one advice how to write rounded numbers without extra zeros? Thanks, Paweł -- Pawe/l Jackowski P.Jackowski(a)gust.org.pl
