Module documentation for Lua files
by Wolfgang Schuster 05 Nov '12

05 Nov '12

Hi Hans, the scripts to generate the documentation from Lua files don’t work in the beta. When I run context --ctx=x-ldx x-ldx.lua not even the xml file “x-ldx.ldx” is generated. When I use the two step method with mtxrun --internal x-ldx x-ldx.lua I get the xml file but the second step context --usemodule=ldx --forcexml x-ldx.ldx gives no output. Wolfgang

Reversed alignment for left and right

Hi Hans, while for backwards compatibility you won’t change \setupalign[leftt|right] the current implementation makes it possible to change the behavior with a simple change in the code. \unprotect \newconstant\c_spec_align_state_method %\setvalue{\??aligncommand\v!right }{\c_spac_align_state_horizontal\plustwo } %setvalue{\??aligncommand\v!left }{\c_spac_align_state_horizontal\plusthree} \setvalue{\??aligncommand\v!right }{\c_spac_align_state_horizontal\ifcase\c_spec_align_state_method\plustwo\else\plusthree\fi} \setvalue{\??aligncommand\v!left }{\c_spac_align_state_horizontal\ifcase\c_spec_align_state_method\plusthree\else\plustwo\fi} \unexpanded\def\enablereversealignment{\c_spec_align_state_method\plusone} \protect %\enablereversealignment \starttext \startalignment[left] \input ward \stopalignment \blank \startalignment[right] \input ward \stopalignment \stoptext Wolfgang

Environments for alignment commands
by Wolfgang Schuster 30 Oct '12

30 Oct '12

Hi Hans, can we add the following definitions to space-ali.mkiv \unexpanded\def\startleftaligned {\doalignline\relax \hss \bgroup} \unexpanded\def\startmidaligned {\doalignline\hss \hss \bgroup} \unexpanded\def\startrightaligned{\doalignline\hss \relax\bgroup} \unexpanded\def\startmaxaligned {\doalignline\relax \relax\bgroup} \unexpanded\def\stopleftaligned {\unskip\egroup} \unexpanded\def\stopmidaligned {\unskip\egroup} \unexpanded\def\stoprightaligned{\unskip\egroup} \unexpanded\def\stopmaxaligned {\unskip\egroup} The \unskip (would be \removeunwantedspaces better?) because otherwise the space at the end of the text appears in the output: \startmidaligned Centered? \stopmidaligned Wolfgang

Combinations and \startcontent/\startcaption commands
by Wolfgang Schuster 30 Oct '12

30 Oct '12

Hi Hans, with the use of \stopcaption a visible space is added to the caption of the combination. Can you change the definition of the command from \let\stopcaption \egroup to \def\stopcaption {\unskip\egroup} or something similar. Example: \starttext \startcombination[2*1] {\framed{Content 1}}{Caption 1} {\framed{Content 2}}{Caption 2} \stopcombination \startcombination[2*1] \startcontent \framed{Content 1} \stopcontent \startcaption Caption 1 \stopcaption \startcontent \framed{Content 2} \stopcontent \startcaption Caption 2 \stopcaption \stopcombination \stoptext Wolfgang

2 patches for grph-inc

Hi Hans, Could you please add these 2 patches (or something similar), because the grph-downsample module¹ would work much better then: 1.)

Wrong counter settings
by Wolfgang Schuster 18 Oct '12

18 Oct '12

Hi Hans, in the following three files the additional check is necessary because otherwise changes for the counter (e.g. prefix=…) would also change the global counter settings from \setupstructurecounting. strc-not.mkvi: \appendtoks - \strc_notes_setup_counter\currentnotation + \ifx\currentnotation\empty \else + \strc_notes_setup_counter\currentnotation + \fi \to \everysetupnotation strc-enu.mkvi: \appendtoks - \strc_enumerations_setup_counter\currentenumeration + \ifx\currentenumeration\empty \else + \strc_enumerations_setup_counter\currentenumeration + \fi \to \everysetupenumeration strc-lab.mkvi \appendtoks - \strc_labels_setup_counter\currentlabel + \ifx\currentlabel\empty \else + \strc_labels_setup_counter\currentlabel + \fi \to \everysetuplabel In the following two files you can remove the \strc_counters_check_setup\… line because it’s already called from \strc_counter_setup_using_parameter in the previous line. strc-flt.mkvi: \appendtoks \let\currentfloat\currentfloatcaption \ifx\currentfloat\empty \else \strc_counter_setup_using_parameter\currentfloatcaption\floatcaptionparameter - \strc_counters_check_setup\currentfloatcaption \fi \to \everysetupfloatcaption strc-mat.mkiv: \appendtoks \strc_counter_setup_using_parameter\v!formula\formulaparameter - \strc_counters_check_setup\v!formula % yes or no \to \everysetupformula Wolfgang
