math-fen.mkiv: \lfence, \rfence and \mfence
by Wolfgang Schuster 15 Sep '15

15 Sep '15

Hi, when you pass a undefined argument to \lfence (or \rfence and \mfence) you get the "unknown" alternative \setvalue{\??mathleft \s!unknown}{\setfalse\c_math_fenced_done\ifconditional\c_math_fenced_unknown\normalleft \nexttoken\fi} which doesn’t work here because \nexttoken is never set by \lfence but only by \left.

Hi Hans, is it intended that you used the same names for \left and \right in the defintions below? \installmathfencepair \ulcorner \Luppercorner \ulcorner \Ruppercorner \installmathfencepair \llcorner \Llowercorner \llcorner \Rlowercorner \installmathfencepair \lmoustache \Lmoustache \lmoustache \Rmoustache \installmathfencepair \llbracket \Lopenbracket \llbracket \Ropenbracket \installmathfencepair \lgroup \Lgroup \lgroup \Rgroup Wolfgang

math-fen.mkvi: \fenced

Hi, the \fenced command doesn’t decrement the nesting counter at the end. \unexpanded\def\math_fenced_fenced[#1]#2% {\math_fenced_fenced_start{#1}% #2% \math_fenced_right \stopusemathstyleparameter - \endgroup} + \endgroup + \advance\c_math_fenced_nesting\minusone} Wolfgang

math-stc.mkvi: \singlebond (was: math-arr.mkiv: \singlebond)

I have no need for the commands, I was only surprised why this happened because it made no sense when you look at the definition of \singlebond in math-arr.mkiv. What I noticed now that Hans redefines the command later in math-stc.mkvi where a number delimiter is missing. When you stop TeX’s number scanner with a \relax you get the right output even with a number after \singlebond. -\unexpanded\edef\singlebond{\mathematics{\mathsurround\zeropoint\char\number"002D}} -\unexpanded\edef\doublebond{\mathematics{\mathsurround\zeropoint\char\number"003D}} -\unexpanded\edef\triplebond{\mathematics{\mathsurround\zeropoint\char\number"2261}} +\unexpanded\edef\singlebond{\mathematics{\mathsurround\zeropoint\char\number"002D\relax}} +\unexpanded\edef\doublebond{\mathematics{\mathsurround\zeropoint\char\number"003D\relax}} +\unexpanded\edef\triplebond{\mathematics{\mathsurround\zeropoint\char\number"2261\relax}} Wolfgang

Hi, the \singlebond (as well as the \doublebond and \triplebond) command doesn’t produce a symbol when you put a number after it. \starttext $ l\singlebond r $\crlf $ 1\singlebond 2 $\crlf %$ 1\doublebond 2 $\crlf %$ 1\triplebond 2 $ \stoptext Wolfgang

font-ini.mkvi: \bodyfontenvironmentlist
by Wolfgang Schuster 14 Sep '15

14 Sep '15

Hi, the allocation of the token list \bodyfontenvironmentlist on line 1192 \newtoks\bodyfontenvironmentlist can be removed because the command is redefined a few lines below. Wolfgang

Hi, the mathcommand defintion in line 151 misses a "colon" in its name. \definemathcommand [approxcoloncolon] [rel] {\approx\coloncolon\colonsep} -\definemathcommand [colonsim] [rel] {\coloncolon\colonsep\sim} +\definemathcommand [coloncolonsim] [rel] {\coloncolon\colonsep\sim} \definemathcommand [simcoloncolon] [rel] {\sim\coloncolon\colonsep} Wolfgang

lxml-ini.lua: \clf_xmlafterdocumentsetup
by Wolfgang Schuster 13 Sep '15

13 Sep '15

Hi, the command \clf_xmlafterdocumentsetup takes three arguments and not two. -implement { name = "xmlafterdocumentsetup", actions = lxml.installsetup, arguments = { 4, "string", "string" } } +implement { name = "xmlafterdocumentsetup", actions = lxml.installsetup, arguments = { 4, "string", "string", "string" } } Wolfgang

lang-lab.mkiv: \commalistsentence
by Wolfgang Schuster 09 Sep '15

09 Sep '15

Hi Hans, the \commalistsentence doesn’t use the default language dependant separator because the Lua function expects “separator" and “last" as variable names but you pass them from TeX with the variables "first" and "second". \def\typo_helpers_concat_comma_list[#1][#2]% {\clf_concatcommalist text {#1}% separators {#2}% first {\detokenize\expandafter{\normalexpanded{\labeltext{and-1}}}}% second {\detokenize\expandafter{\normalexpanded{\labeltext{and-2}}}}% \relax} Wolfgang

Font key for \language
by Wolfgang Schuster 08 Sep '15

08 Sep '15

Hi Hans, the processing of the font key for \language doesn’t work because \feature takes the value as an unknown argument. \appendtoks \edef\p_language_font{\languageparameter\s!font}% \ifx\p_language_font\v!auto - \feature\currentlanguage + \doaddfeature\currentlanguage \fi \to \everylanguage Wolfgang
