Detect an empty page of a .pdf?
by Procházka Lukáš Ing. 11 Jul '16

11 Jul '16

Hello, is there a ConTeXt-Lua way to detect whether i-th page of a .pdf is empty (meaning "has no text on it")? Best regards, Lukas -- Ing.

Dear list, I have the following sample: \setupexternalfigure[location=default] \starttext \insertpages[cow.pdf][width=\textwidth] \stoptext Using latest beta from 2016.07.08 17:19, scaling doesn’t work. Am I missing something or have I hit a bug? Just in case it might me causing the issue, I’m using LuaTeX-0.95 for Linux 32bit. Could anyone check this issue? Many thanks for your help, Pablo -- http://www.ousia.tk

Issue with tex.hangindent with latest beta 2016-07-08 17:24
by josephcanedo＠gmail.com 10 Jul '16

10 Jul '16

Dear list, In some lua code I have in my project, I’ve started getting this error when upgrading to latest beta (used to work fine for lots of versions for months) : attempt to perform arithmetic on field 'hangindent' (a nil value) when using expression: tex.hangindent in lua code. I am quite sure hangindent is not zero for this paragraph (on purpose). Is there a change in way to access hangindent value for a paragraph ? Many thanks Best regards Joseph Canedo

Invoking ConTeXt from inside php web appliction
by Pavneet Arora 10 Jul '16

Dear Hraban, Sorry that this has taken me so long. The report card application has been deployed, and although I am still going through and resolving minor bugs, it is very much in use (350 students leaving on Tu who already have their foundation work marked and commented within the system; output via ConTeXt). Anyway, I have updated the Wiki, but am unsure if I missed anything. So can everyone have a look and let me know: http://wiki.contextgarden.net/ConTeXt_Standalone#Apache_webserver_installat… Regards. > Henning Hraban Ramm texml at fiee.net > Fri Jun 17 20:49:11 CEST 2016 > > Please document this in the wiki (I had similar problems, should have done it at that time) -- Pavneet Arora m: 647.406.6843 Waroc Informatik w: 416.937.9276

Thanks for the kind words, Luigi. Glad you enjoyed the interview. It is a bit unsettling to find that you have revealed so much about yourself ;). Dave is an excellent interviewer.

\defineparagraphs

The code below works with context2016.02.15, but fails with context2016.05.19. Itemize within the defined paragraph (Mypar) no longer puts the thinrule in the margin (see the third question.) The \ansblank command seems to the second part of Mypar is the margin? Pdf of the success and fail attached. Thanks! John \defineparagraphs[Mypar][n=2] \setupparagraphs[Mypar][1][width=0.5\textwidth] % label subquestions (a, b, c, etc) with answerblanks \defineconversionset[myitemize][n,a][n] % define the answerblank in right margin \define\ansblank {\inright{\simplealignedbox{2em}{flushleft}{\convertedcounter[itemgroup:itemize][numberconversionset=myitemize,numberstopper=.]}\thinrule}\ignorespaces} % \define\noblank \define\noblank {\inright{~}} % put them together to toggle printing of the answerblank \define\blankon{\setupitemgroup [itemize] [style=bold,command=\ansblank]} \define\blankoff{\setupitemgroup [itemize] [style=bold,command=\noblank]} \starttext \showframe \startitemize[n] \blankon \item First question. \blankoff \item Second question has two parts. \startitemize[a] \blankon \item subquestion a \item subquestion b \stopitemize \blankon \startMypar \item Third question refers to graphic at right. \Mypar <A graphic/MPcode goes herer> \stopMypar \item Final question. \stopitemize \stoptext

ppchTeX
by Henri Menke 09 Jul '16

09 Jul '16

Dear list, I just wanted to check whether chemical structures typeset in ConTeXt can be exported as XML. Therefore I wanted to setup a simple example with ppchTeX. I copied example 3.1 from the manual [1] > \usemodule[chemic] > \starttext > > \startchemical[height=4500,bottom=2500] > \bottext{$\beta$-D-Fructopyranose} > \chemical[SIX,FRONT,BB1236,+SB4,-SB5,Z5][O] > \chemical[SIX,FRONT,+R12346,+RZ12346][\SR{HO},H,H,H,OH] > \chemical[SIX,FRONT,-R12346,-RZ12346][H,OH,\SR{HO},H,CH_2OH] > \stopchemical > > \stoptext Unfortunately, typesetting with MkIV distributed with TL 2016 produces something really weird (see attached). Is the module `chemic` compatible with MkIV or am I doing something wrong? Cheers, Henri [1] http://www.pragma-ade.nl/general/manuals/mp-ch-en.pdf
