slashes in paths (Lua code)

Dear list, I need to add checksums to files I attach to PDF documents. Following the suggestion from https://stackoverflow.com/a/326715, I wrote: \starttext \startluacode function document.capture(cmd, raw) local f = assert(io.popen(cmd, 'r')) local s = assert(f:read('*a')) f:close() if raw then return s end s = string.gsub(s, '^%s+', '') s = string.gsub(s, '%s+$', '') s = string.gsub(s, '[\n\r]+', ' ') return s end function document.sha256(file) command_output= document.capture("sha256sum -b " .. file) context(command_output:sub(0,64)) end function document.sha512(file) command_output= document.capture("sha512sum -b " .. file) context(command_output:sub(0,128)) end \stopluacode \def\shatwo#1% {\ctxlua{document.sha256("#1")}} \def\shafive#1% {\ctxlua{document.sha512("#1")}} \shatwo{Desktop/i-context.pdf} \shafive{i-context.pdf} \stoptext Directories are a problem here. I mean, \shatwo{Desktop/i-context.pdf} cannot work in Windows. Which would be the way to make it work in Windows? Many thanks for your help, Pablo -- http://www.ousia.tk

mathmatrix and grid: followup
by Henri Menke 01 Jun '17

01 Jun '17

Dear list, some time ago I asked about the interplay of mathmatix with grid typesetting: https://mailman.ntg.nl/pipermail/ntg-context/2016/087018.html I noticed that when the grid is enabled, the height of a mathmatrix is rounded down which leaves less space above than below. In my opinion either the height should be rounded up or the depth rounded down here. In the original thread Wolfgang proposed using \setupformula[grid=tolerant] and adding a blank line before the formula (otherwise grid=tolerant is applied to the paragraph before). This workaround leads to the depth being rounded down in the example below which produces a more balanced output. Could this somehow be made the default behaviour or something? Currently it requires the user to notice that vertical spacing is off and correct it manually, including adding a blank line before the formula to prevent grid=tolerant being applied to the paragraph. Cheers, Henri --- \setuplayout[grid=yes] \showgrid \starttext \input knuth \startformula \vrule % make lineheight and depth visible \startmathmatrix \NC A \NR \NC B \NR \NC C \NR \stopmathmatrix \stopformula \input tufte \stoptext

Modes in Lua
by Henning Hraban Ramm 01 Jun '17

01 Jun '17

Hi, this should be easy: How can I access ConTeXt’s modes in Lua? Is it any different with language modes (*en)? e.g. \startluacode if context.modes['specialmode'] then context('I’m special.') end \stopluacode Greetlings, Hraban --- http://www.fiee.net http://wiki.contextgarden.net GPG Key ID 1C9B22FD

Fw: APA Bibliographic refs. | Hyphenated first names | Lower case first letter of Title

Dear Readers, Following up on this post ... I've recently updated to `ConTeXt ver: 2017.05.28 19:30 MKIV beta' and have found that the APA code base seems to have changed a little. Previously (BibTeX ---> ConTeXt output): Hans-Georg Gadamer and H.-G. Gadamer &c. ---> H. -G. Gadamer but now I'm getting: ditto ---> HG. Gadamer Is this possible instead?

Hi, Hans— The problem with mathmode in footnotes is gone with the latest beta. And without any adverse side effects in any of my projects. My thanks to you and Wolfgang for your work on this.

aligning a table alignment with local footnotes
by Alan Bowen 30 May '17

30 May '17

What is the best way to center a table and control/fix the textwidth of the local footnotes? I currently have: \starttext \startbuffer[Tab01] \startlocalfootnotes \bTABLE \bTR\bTD So\eTD\bTD what% \footnote{\input knuth} % <= \eTD\eTR \eTABLE {\placelocalfootnotes} \stoplocalfootnotes \stopbuffer \startplacetable[title=Test, align=middle] {\getbuffer[Tab01]} \stopplacetable \stoptext If the footnote is commented out, the table is centered (as I want it). With the footnote, the table is flushleft. I have managed to get what I need by defining the \hsize of the footnotes and tweaking the loffset of the table. But a general, less “empirical” approach would be vastly better. Alan Alan

Many thanks, Hans. This is very fine solution for the tables that I have, since they are quite wide.

Formula numbers in RTL mode
by Mohammad Hossein Bateni 28 May '17

28 May '17

Hi Hans, I recall something like this was reported a few months back, and you said you were reworking math alignment mechanisms at the time. Now that you're getting ready for the Tex Live version, I want to bring attention to this issue once again, in the hope of getting it resolved. Formula numbers are not placed at the far end when in RTL. Here is a MWE: \starttext \input knuth \placeformula \startformula E = mc^2. \stopformula \righttoleft \placeformula \startformula E = mc^2. \stopformula \stoptext Attached is the result from context version 2017.05.14 19:09. Using \setupformula[location=left] gives similar results with directions swapped: output is as desired in LTR but slightly off the edge in RTL. Thanks, MHB
