Hyphenation again
by Denis Maier 06 Jun '21

06 Jun '21

Hi, another weird thing: In this example I use \startexceptions to set hyphenation exceptions: ``` \mainlanguage[en] \startexceptions[en] appli-cable obli-gated \stopexceptions \setuplayout[width=1cm] \starttext \currentmainlanguage \currentlanguage \hyphenatedword{applicable} applicable \hyphenatedword{obligated} obligated \stoptext ``` What am I missing? Best, Denis

Converting footnotes to endnotes
by Idris Samawi Hamid ادريس سماوي ح امد 05 Jun '21

05 Jun '21

Dear gang, Generally, I do not use endnotes - see Robert Bringhurst's criticisms of endnotes in typography - but a publisher is demanding them. Converting footnotes to endnotes must be quite simple yet I'm missing it: \setupnotation[footnote] [way=bychapter] % \setupnote[footnote] % [way=bychapter] \starttext \startsection[title={},reference={}] \input ward \startfootnote \input ward \stopfootnote{} \input ward \startfootnote \input ward \stopfootnote{} \stopsection \startsection[title={},reference={}] \input ward \startfootnote \input ward \stopfootnote{} \input ward \startfootnote \input ward \stopfootnote{} \stopsection \startsubject[title={},reference={}] \placenotes [footnote] \stopsubject \stoptext What's the best way to convert the above to endnotes? Thank you in advance! Best wishes Idris -- Idris Samawi Hamid, Professor Department of Philosophy Colorado State University Fort Collins, CO 80512

issue with link (MkIV & LMTX)

Dear list, I have the following sample: \setuppapersize[A10] \setupinteraction[state=start] \enabledirectives[references.border] \unexpanded\def\MyURL#1% {\bgroup\goto{{\tt\hyphenatedurl{#1}}}[url(#1)]\egroup} \starttext \startTEXpage[offset=1ex] \startitemize \item \MyURL{a.b\\/c.d\letterhash e} \stopitemize \stopTEXpage \stoptext I’m using current latest from 2021.06.04 17:28. LuaTeX generates the link rectangle right. LuaMetaTeX generates a wrong link rectangle. In the attached image, you can see the output I get (MkIV and LMTX). Could anyone confirm the issue? Many thanks for your help, Pablo -- http://www.ousia.tk

Hi♥ How do I get the quotes to potrude out in the left margin? For example in the following text, I want the "y" in "you are so" to be aligned with the "oh" in "oh hi there" and the "here" in "here here". \definefontfeature [default] [default] [protrusion=quality,expansion=quality] \setupalign[hz,hanging] \starttext oh hi there "you are so" here here \stoptext Also in the real text I'll also be using \definefontfamily [praise][serif][junicode] but, the above min via behavior I couldn't get to work at live.contextgarden

yscale not working
by Hans van der Meer 05 Jun '21

05 Jun '21

Why is there no effect of the yscale parameter in \externalfigure when the width-parameter is given? In the MWE it is the intention to stretch the height of the figure by a factor of two. But nothing happens. Leaving out the width does stretch the height, but then it becomes too wide. \starttext Test \tex{externalfigure} scaling - \ConTeXt\ \contextversion \blank \type{\externalfigure[test][width=0.50\textwidth]}\crlf \externalfigure[test][width=0.50\textwidth] \blank \type{\externalfigure[test][width=0.50\textwidth,yscale=2000]}\crlf \externalfigure[test][width=0.50\textwidth,yscale=2000] \stoptext dr.

Struggling with SQL!
by Gerard Verhaag 05 Jun '21

05 Jun '21

Hi, I'm trying to get MySQL data access working but can't solve the issues I'm encountering. Part of my code looks like: \startluacode productsheet = productsheet or {} function productsheet.sqldatabase(database,user,password) productsheet:sql(database,user,password) end function productsheet:sql(db,us,pw) print("SQLDATABASE: database: " .. db) print("SQLDATABASE: username: " .. us) print("SQLDATABASE: password: " .. pw) local sql = require("util-sql") local presets = {database = db,username = us,password = pw,host= "localhost",port= 3306} local template = [[SELECT `nom`, `name_alias` FROM `llx_societe` WHERE `nom` = '%nom%' ;]] presets.id = "mysql" local data, keys = utilities.sql.execute {presets=presets,template=template,variables={nom = "Life"}} ... This generates the following issues: sql > start loading method 'library' lua error > lua error on line 153 in file /home/gverhaag/Stock/ProductSheet/productsheet_KG594.tex: /usr/share/texmf/tex/context/base/mkiv/l-sandbox.lua:180: module 'luasql.mysql' not found: no field package.preload['luasql.mysql'] no file '/usr/local/share/lua/5.2/luasql/mysql.lua' no file '/usr/local/share/lua/5.2/luasql/mysql/init.lua' no file '/usr/local/lib/lua/5.2/luasql/mysql.lua' no file '/usr/local/lib/lua/5.2/luasql/mysql/init.lua' no file './luasql/mysql.lua' no file '/usr/local/lib/lua/5.2/luasql/mysql.so' no file '/usr/local/lib/lua/5.2/loadall.so' no file './luasql/mysql.so' no file '/usr/local/lib/lua/5.2/luasql.so' no file '/usr/local/lib/lua/5.2/loadall.so' no file './luasql.so' stack traceback: [C]: in function 'requiem' /usr/share/texmf/tex/context/base/mkiv/l-sandbox.lua:180: in function </usr/share/texmf/tex/context/base/mkiv/l-sandbox.lua:165> (...tail calls...) ...are/texmf/tex/context/base/mkiv/util-sql-imp-library.lua:74: in main chunk [C]: in function 'requiem' /usr/share/texmf/tex/context/base/mkiv/l-sandbox.lua:180: in function </usr/share/texmf/tex/context/base/mkiv/l-sandbox.lua:165> (...tail calls...) /usr/share/texmf/tex/context/base/mkiv/util-sql.lua:114: in function '__index' /usr/share/texmf/tex/context/base/mkiv/util-sql.lua:288: in function 'execute' [ctxlua]:21: in function 'sql' [ctxlua]:5: in function 'sqldatabase' [ctxlua]:1: in main chunk Must be something basic, I guess!

different prefixsegments for \in
by Pablo Rodriguez 04 Jun '21

04 Jun '21

Dear list, I have the following sample: \setupreferencestructureprefix [default] [prefixsegments=*:*] \starttext \section{One Section} \subsection[sec0]{Subsection} As told in \in[sec0] and \in[sec1]… \section{Another Section} \subsection[sec1]{Subsection} … \stoptext The output reads: As told in 1.1 and 2.1… I would like to be able to supress the section number in the reference, if the current section is the same as the referenced one. I mean, I would like that the output reads: As told in 1 and 2.1… Which would be the way to do it automatically? BTW, in my real--world document, I need to remove part and chapter numbers from the reference when in the same part and chapter (when compiling XML sources). Many thanks for your help, Pablo -- http://www.ousia.tk

new upload
by Hans Hagen 04 Jun '21

04 Jun '21

Hi, I uploaded a new version of lmtx: a next step in this matrix and such graphic part ... (also bTABLE done). The matrix bit has a high level MP interface, also because it's a nice example of implementing one (not much code needed actually). Support in bTABLE .. eTABLE is kind of interesting as it separates the ornamental part from the text part. The sxample only shows some simple stuff. I'll probably also add this to the other table mechanisms. (Not hard but I don't want to impact performance when it's not used.) The \startoverlayMPgraphic{mp:whatever-6} is new and automatically defines the overlay so that saves some code. \startMPoverlaydata is just a collector that can be flushed in-line (which wilkl also reset it). All this is probably mostly useful in an educational setting. We'll see.

metafun transformation error
by Ajith R 04 Jun '21

04 Jun '21

Hi all, I am new to context and need help in solving an error. I am trying to print some numbers in a grid onto a transparent sheet as mirror images so that the numbers are correctly displayed when I view it from the non printed side. The numbers have a particular sequence which cannot be obtained from calculations. So, they are stored in an array of strings : l[0][0] := "38"; ... I place them at the centre of the grid squares using the code below: for i= 0 upto (row - 1): for j= 0 upto (col - 1): middle := 0.5[((( i * unit) + lm), ((j * unit) + bm)), ((((i+1) * unit) + lm), (((j +1) * unit) + bm))]; p := thelabel(l[j][i], middle); draw p; % q := p reflectedabout (0.5[urcorner p, ulcorner p], 0.5[lrcorner p, llcorner p]); % draw q; endfor endfor This works as expected. But, when I try to reflect the label by means of the commented code, I get an error : tex error > mp error on line 643 in file /home/ajith/Desktop/PlayGround/numgrid.tex: >> (xpart T_,ypart T_,-0.00581xpart T_+0.00497ypart T_+0.15294,-0.00497xpart T_ -0.00581ypart T_+0.98824,-0.00497xpart T_-0.00581ypart T_+0.98825,0.00581xpart T_-0.00497ypart T_-0.15294) !

Proceed, and I'll omit the transformation. I tried a mock example without the loops and that didn't throw an error. How can I make it work within the loops? Thanks, ajith
