Luatex 1.08.0 announcement
by luigi scarso 28 Oct '19

28 Oct '19

============================================================== LuaTeX 1.08 2018-08-28 ============================================================== (1) This release is a prelude to 1.10, the next stable iteration of LuaTeX after version 1.00. (2) Lua 5.3 is now considered to be default and we might use 5.4 in version 1.10. There are no real functional changed expected. You still need to rename the binary for 5.3! (3) Binary mode is no longer available in MPlib but it is still available in stand alone MetaPost. This simplifies compilation and reduces dependencies. (4) The dependency on Poppler for pdf image inclusion has been removed. We now use a small dedicated library written by Pawel Jakowski. We no longer need c++ compilers. We're in the process of making it behave well on all platforms. It has been tested on intel platforms. (5) We know that there can be some (alignment) issues with the arm platform but these are looked into. Therefore, later this year we will release 1.09. Version 1.10 is planned for TeXlive. We hope that ffi works ok on intel and arm platforms at that point. (6) There have been some extensions to the Lua libraries and some callbacks have been added. Also, a few new primitives have been introduced. The documentation mentions the stable extensions. (7) There are the usual bug fixes and cleanups but there have been no real fundamental changes in the API. The LuaTeX team

Hi Hans, when you use “text” alternative for \setuphead and enable text indentation the paragraph after the section title isn’t indented. \setupindenting[yes,big] \setuphead[section][alternative=text] \starttext \section{Introduction} \input knuth \stoptext This is caused by the \noindentation (needed for the “margintext” alternative) in \strc_rendering_stop_placement, adding a check for \headissomewhere fixes it. \def\strc_rendering_stop_placement {\n_strc_rendering_hang_lines\zerocount ... \ifconditional\headisdisplay \useindentnextparameter\headparameter \else - \ignoreparskip - \noindentation % recently added, was a bug + \ifconditional\headissomewhere + \ignoreparskip + \noindentation + \else + \ignoreparskip + \fi \fi} Wolfgang

Hi, the conditional for ##3 is wrong (should be true). \unexpanded\def\processassignlist#1[#2]#3% {\def\syst_helpers_process_assign_list_assign[##1=##2=##3]% - {\doifnot{##3}\relax{#3{##1}}}% + {\doif{##3}\relax{#3{##1}}}% \def\syst_helpers_process_assign_list_step##1% {\syst_helpers_process_assign_list_assign[##1==\relax]}% \processcommalist[#2]\syst_helpers_process_assign_list_step} Wolfgang

Caption in floatcombination is too low
by Wolfgang Schuster 06 Feb '19

06 Feb '19

Hi Hans, there is a big gap between the content and the caption of each float in a floatcombination environment. %%%% begin example \useMPlibrary[dum] \starttext \startplacefigure[title={First graphic}] \externalfigure[one] \stopplacefigure \startfloatcombination \startplacefigure[title={Second graphic}] \externalfigure[two] \stopplacefigure \stopfloatcombination \stoptext %%%% end example This is probably a result of the following two command from strc-flt.mkvi where you put the caption in a \vbox with a height of 1pt and flush it afterwards in \vtop which shifts the content down to the baseline. As a result of this a empty space was added at the top of the caption. A simple fix for this is to raise the box with the caption when it is added to the combination. %%%% begin strc-flt.mkvi \def\strc_floats_build_box_separate_make {\offinterlineskip \vpack to \onepoint{\box\b_strc_floats_content}\break \vpack to \onepoint{\box\b_strc_floats_caption}} \def\strc_floats_build_box_separate_split#1% {\setbox\scratchbox\vbox{% \setbox\scratchbox\vpack{#1}% \unvbox\scratchbox\relax \setbox\scratchbox\lastbox %\doloop{% \unvbox\scratchbox \setbox\scratchbox\lastbox % \ifdim\ht\scratchbox=2\onepoint \unvbox\scratchbox \setbox\scratchbox\lastbox % \exitloop % \fi}% \splittopskip\zeropoint \global\setbox\b_strc_floats_separate_content\vsplit\scratchbox to \onepoint \global\setbox\b_strc_floats_separate_caption\vsplit\scratchbox to \onepoint \global\setbox\b_strc_floats_separate_content\vpack{\unvbox\b_strc_floats_separate_content\setbox0\lastbox\unvbox0}% \global\setbox\b_strc_floats_separate_caption\tpack{\unvbox\b_strc_floats_separate_caption\setbox0\lastbox\unvbox0}% }} %%%% end strc-flt.mkvi Wolfgang

Hi, In the definition of “setupcolumns”, there are two cd:inherits misrepresented as cd:constants: <cd:parameter name="align"> <cd:constant type="setupalign"/> </cd:parameter> <cd:parameter name="tolerance"> <cd:constant type="setuptolerance"/> </cd:parameter> Best wishes, Taco

math-ini.mkiv: \mathminus
by Wolfgang Schuster 05 Feb '19

05 Feb '19

Hi Hans, the definition for \mathminus uses a en dash for math mode which seems wrong to me. Shouldn’t math use a normal hyphen character? \unexpanded\def\mathminus{\ifmmode –\else\iffontchar\font`−−\else –\fi\fi} Wolfgang

Hi Hans, you pass the wrong argument (#1 instead of #2) to the Lua function for the \date command. \def\syst_converters_date[#1][#2]% {\dontleavehmode \begingroup \scratchcounterone \normalyear \scratchcountertwo \normalmonth \scratchcounterthree\normalday \iffirstargument \letdummyparameter\c!y\empty \letdummyparameter\c!m\empty \letdummyparameter\c!d\empty \getdummyparameters[#1]% \edef\temp{\dummyparameter\c!y}\ifx\temp\empty\else\scratchcounterone \temp\fi \edef\temp{\dummyparameter\c!m}\ifx\temp\empty\else\scratchcountertwo \temp\fi \edef\temp{\dummyparameter\c!d}\ifx\temp\empty\else\scratchcounterthree\temp\fi \relax \fi \the\everycurrentdate \clf_currentdate - {#1}{\currentdatespecification}{\labellanguage}% + {#2}{\currentdatespecification}{\labellanguage}% \scratchcounterone\scratchcountertwo\scratchcounterthree \endgroup} Wolfgang
