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, the argument check in \cmd_show_setup_yes has to go away. \def\cmd_show_setup_yes[#1]% - {\iffirstargument - \cmd_show_setup_nop{#1}% - \else - \expandafter\cmd_show_setup_nop - \fi} + {\cmd_show_setup_nop{#1}} Wolfgang

tabl-xtb.lua xtables and samepage option
by Wolfgang Schuster 16 Nov '18

16 Nov '18

Hi, the samepage option for xtables doesn’t work because of bugs in the Lua code. 1. On line 895 the value has to be taken from the rp-variable itself. 2. On line 905 the second index to get the value for the samepage option is missing. function xtables.construct() ... result[nofr] = { hbox, size, i < nofrange and rowdistance > 0 and rowdistance or false, -- might move false, - rp and rp.samepage or false, + rp or false, } end end if nofr > 0 then -- the [5] slot gets the after break result[1] [5] = false result[nofr][5] = false for i=2,nofr-1 do - local r = result[i] + local r = result[i][5] if r == v_both or r == v_before then result[i-1][5] = true elseif r == v_after then result[i][5] = true end end end return result end ... end Wolfgang

Hi Hans, can you add \setupxml[\c!entities=\v!yes] to the module because I need a few entities (&blank; and &percnt;) from the extended list. Wolfgang

ARMv7 hardfp or softfp detection
by Sebastian Miele 09 Nov '18

09 Nov '18

first-setup.sh from ConTeXt standalone contains the following lines: readelf -A /proc/self/exe | grep -q '^ \+Tag_ABI_VFP_args' if [ ! $? ]; then That probably does not work as intended, because [ ! $? ] is equivalent to [ ! -n $? ]. It does not return the negation of the return code of the previous command. [ ! 0 ] and [ ! 1 ] both have exit code 1, because the strings '0' and '1' are both non-null. Probably no-one actually uses ARMv7 with softfp, including me.

Adding before and after keys to setupcaption
by Aditya Mahajan 01 Nov '18

01 Nov '18

Hi Hans, There have been a few questions on TeX.SX asking essentially for a frame around a float that covers both the caption and the content. 1. https://tex.stackexchange.com/questions/25180/adding-a-frame-and-background… 2. https://tex.stackexchange.com/questions/457412/context-place-rules-above-an… I have provided a hacky solutions to both questions (the internals changed quite a bit between the two questions), but as I was playing around with the code, I thought that the simplest solution will be to add a `before` and an `after` key to `\setupcaptions`: \def\strc_floats_build_box {\global\setbox\floatbox\vbox % pack ? probably not {\strc_floats_set_local_hsize \forgetall \ifconditional\c_floats_store_minimal_package \strc_floats_build_box_separate_make \else % \let\floatcaptionarrangement\s!default \let\floatcaptionarrangement\v!bottom % for Alan \processcommacommand[\floatcaptionparameter\c!location]\strc_floats_build_box_step \floatcaptionparameter\c!before %AM: Added \ifcsname\??floatbuilder\floatcaptionarrangement\endcsname \lastnamedcs \else \strc_floats_build_box_default \fi \floatcaptionparameter\c!after %AM: Added \fi}} A simple usage example is the following: \setupexternalfigures[location={local,global,default}] \setupcaption [ before={\startframedtext[widht=fit, background=color, backgroundcolor=gray, frame=off]}, after=\stopframedtext, ] \starttext \section{A figure with rules} \startplacefigure[location={left,high},title={A dutch cow}] \externalfigure[cow] \stopplacefigure \input knuth \startplacefigure[title={\input zapf \relax}] \externalfigure[cow] \stopplacefigure \dorecurse{4}{\input knuth \endgraf} \stoptext Does it make sense to add this or something similar? Thanks, Aditya
