Lua equivalent of \getvariable{}{}
by Pablo Rodriguez 11 Oct '20

11 Oct '20

Dear list, I have the following sample: \starttext \ctxlua{ context.setvariable("environment", "filename", "abc123") } \ctxlua{ c = context.getvariable("environment", "filename") or "a" } \ctxlua{ d = [[\env{filename}]] } c: \cldcontext{c}\\ \doifelse{\cldcontext{c:match("\letterpercent d+")}} {123}{yes}{no}\\ d: \cldcontext{d}\\ \doifelse{\cldcontext{d:match("\letterpercent d+")}} {123}{yes}{no} \stoptext Which is the Lua equivalent of \getvariable{}{}? I get nil now. BTW, I wonder why \setvariable prints the variable, botn in Lua and ConTeXt. Many thanks for your help, Pablo -- http://www.ousia.tk

\setregisterentry levels with colon (keys:1, entries:1) in lua
by Jano Kula 10 Oct '20

10 Oct '20

Greetings! One can can set register levels with keys and entries \setregisterentry[MyIndex] [keys:1=Sorting Key Level 1, entries:1=Entry Level 1, keys:2=Sorting Key Level 2, entries:2=Entry Level 2] Rewriting the code in lua works until colon (:) is used. \startluacode context.setregisterentry({ "MyIndex" }, { keys:1="C Level 1", entries:1="C Level 2"}) \stopluacode which stops with error: <name> expected near '1' Can the colon be escaped or underlying \xdef\currentregisterkeysa{\registerparameter{\c!keys:1}}% \xdef\currentregisterkeysb{\registerparameter{\c!keys:2}}% \xdef\currentregisterkeysc{\registerparameter{\c!keys:3}}% redefined? Tried without success. MWE (mkiv, latest beta) attached. Thank you, Jano

problem with string matching
by Pablo Rodriguez 10 Oct '20

10 Oct '20

Dear list, I have this sample: \starttext \startluacode a = "asdfasd123" b = a:match("%d+") context(b) c = "123" context(c) if b==c then context("yes") else context("no") end function document.numbers_only(str) context(str:gsub("[%a%p]", "")) end function document.only_numbers(str) context(str:match("%d+")) end function document.compare_strings(one, two) if one == two then context("Yes") else context ("No") end end \stopluacode \unexpanded\def\numbersonly#1% {\ctxlua{document.numbers_only("#1")}} \unexpanded\def\onlynumbers#1% {\ctxlua{document.only_numbers("#1")}} \unexpanded\def\comparestrings#1#2% {\ctxlua{document.compare_strings("#1", "#2")}} \def\rstring{abc123} \numbersonly{abc123} \onlynumbers{abc123} \doifelse{\numbersonly{\rstring}}{abc123}{yes}{no} \doifelse{abc123}{\onlynumbers{\rstring}}{yes}{no} \comparestrings{\numbersonly{\rstring}}{123} \comparestrings{123}{123}, \comparestrings{1}{123} \stoptext I need to extract the digits from a string, which actually comes from the "--arguments" option in the command line. I need to compare the string with real numbers. But for some reason unknown to me, this is more complex than I thought. Could anyone explain me what I am doing wrong? Many thanks for your help, Pablo -- http://www.ousia.tk

\doifelse not working, \doiftextelse breaking
by Pablo Rodriguez 09 Oct '20

09 Oct '20

Dear list, I have the following sample: \starttext \startluacode function document.starts_with(str, start) if str:sub(1, #start) == start then context(start) end end \stopluacode \unexpanded\def\startswith[#1][#2] {\cldcontext{document.starts_with("#1", "#2")}} \startswith[getjobid764572121][getjobid] yes: \doifelse{\startswith[getjobid764572121][getjobid]}{getjobid} {yes}{no} no: \doifelse{\startswith[getjobid764572121][getjobid]}{} {yes}{no} %% \doiftextelse{\startswith[getjobid764572121][getjobid]} % {yes}{no} \stoptext I don’t know why comparing doesn’t work with \doifelse. I’m surprised that \doiftextelse breaks when \startswidth if inside. How could i make \startswith work inside \doiftext? Or how could I catch positives when command contents start with a given string? Many thanks for your help, Pablo -- http://www.ousia.tk

Local custom notes affect regular footnotes
by Henning Hraban Ramm 09 Oct '20

09 Oct '20

If I use local notes, regular footnotes disappear in the following example: \definenote[testnote] \starttext \startlocalnotes[testnote] Test\testnote{Custom note} Other text inbetween with normal footnotes.\footnote{Footnote} Test\testnote{Another custom note} Other text afterwards with normal footnotes.\footnote{Other Footnote} :::\placelocalnotes[testnote] ::: ---\placelocalnotes[footnote] --- % just to be sure, no output %\stoplocalnotes % a NOP? \stoptext (LMTX or MkIV 2020.09.20 23:02) The use case is a commented edition of historical letters. Footnotes of letter contents should be local and numbered per letter, while general footnotes should behave as usual and are numbered by text. (This setup works otherwise, no need to explain.) Actually, the “normal text” part appears only after a letter, but before \placelocalnotes. The logical structure would be: \startlocalnotes[testnote] \startnarrower \input lorem\testnote{bla bla} \input lorem\testnote{bla bla} \stopnarrower \stoplocalnotes % forgets local notes \input knuth\footnote{Donald dixit} \placelocalnotes[testnote] % nothing In the MWE, the footnotes just disappear. In the actual project the problem is different, but I couldn’t reproduce it in a MWE. I guess the interference of different note types is the cause of both problems. I tried using the same custom note for the last comment as a workaround, but it gets placed twice: once at the bottom of the current page (i.e. like a normal footnote, out of order) and once after the other custom notes. (The letter is in a delimitedtext environment.) Hraban

Fine tuning an index
by Duncan Hothersall 09 Oct '20

09 Oct '20

I'm doing my first mkiv index (it took me a long time to upgrade from mkii!) and I really like the processor feature to format elements differently. But there are a couple of things I would really like to achieve that I'm struggling with: 1. Elided numbers in an index range entry. For example if I have a \startregister - \stopregister pair resulting in an index entry like entry 354--356 I would like to be able to make this read entry 354--6 There are different conventions for number span elision but usually teens aren't elided so entry 314--316 would become entry 314-16. It strikes me that if I could set up a processor specifically for page number ranges I could possibly write a macro to do elision; but I don't think that's currently possible? Maybe it's possible in lua to write code which both identifies range page numbers and carries out the elision. I'm not quite sure where to start. 2. Fine tuning column and page breaking in an index. This is tricky, because there are usually very few "good" places to break an index, and automatic breaking seems to alter slightly depending on whether interactions are set up or not, but is there a way to manually insert a column or page break into the register before or after a certain entry, the way there is for a table of contents? Sorry for no MWE, for obvious reasons. Any pointers to what might be able to be done on these would be much appreciated. Thanks. Duncan

Hyperref-style borders around clickable links
by Denis Maier 08 Oct '20

08 Oct '20

Hi, I prefer links to be styled as normal text, but I'd nevertheless to highlight them somehow on screen. The LaTeX package Hyperref adds red frames to clickable content. Is something like that possible with ConTeXt? Best, Denis
