Component of a product (correction!)

Hello, suppose the following case: ---- Book.mkiv \startproduct * \component A.mkiv \component B.mkiv \stopproduct ---- ---- A.mkiv \startcomponent * \section{A} \stopcomponent ---- ---- B.mkiv \startcomponent * \section{B} \stopcomponent ---- When compiling "Book.mkiv", I'm getting the following sections (obviously): 1. A 2. B Similarly, when compiling "A.mkiv", I'm getting: 1. A and for "B.mkiv": 1. B But: is there a way to say to ConTeXt - when compiling just B.mkiv - that B.mkiv is supposed to be a part of a product (Book.mkiv) and so that the chapter should be numbered from 2, so to get: 2. B ... <<<--- Correction here compared with the previous mail ? I supposed that project/product/component abilities of ConTeXt were mentioned for this, but...? Best regards, Lukas -- Ing.

How to typeset differential (math)?
by Procházka Lukáš Ing. - Pontex s. r. o. 17 Jun '15

17 Jun '15

Hello, how to typeset differential in math correctly? Here are my attempts: ---- \definemathcommand[dif][nolop]{\mfunction{d}} % Based on http://wiki.contextgarden.net/Math/functions \starttext \startformula \sin x {\tf d} x \stopformula \startformula \sin x \dif x \stopformula \stoptext ---- But: - case 1: there is no space between "d" and "x" (should be similar to that between "sin" and "x") - case 2: "d" in the formula is shifted down (?!) somehow. So - ? Other questions: I need to typeset some math text. - Variables should be typeset slanted, which is OK (see "x" in the example). - Functions (sin, log... "d" in df/dx) should be typeset non-slanted - I guess \definemathcommand is supposed for this (or is there a better way?). - Vector variables should be typeset bold slanted - is there a special command for this? (\vec adds arrow above the expression, so it is not supposed for this). Thank you in advance. Best regards, Lukas -- Ing.

BBEdit Language Module for ConTeXt
by Paul Mazaitis 16 Jun '15

16 Jun '15

Hello, list! I've been working on a BBEdit language module to support editing ConTeXt files: https://github.com/pmazaitis/ConTeXtBBLM ...with binary releases here: https://github.com/pmazaitis/ConTeXtBBLM/releases If there are other BBEdit users here with interest, I'd appreciate feedback. Notes on feature gaps (math?), outright bugs, improvements, and/or fiddly details are all welcome. Thanks! -Paul

Problem with rfc4180splitter in last beta?
by Jaroslav Hajtmar 15 Jun '15

15 Jun '15

Hi Hans, I encountered while experimenting with the latest beta version of standalone context to a problem when using the splitter. When I process without header file then compilation crashed when you compile the latest beta version. Conversely, the processing of a header file is no problem. ConTEXt while compiling the 2014 TL is fine in both cases. I do not know from which beta version was a problem, I discovered it by accident until now. Send minimal example. When gCSVHeader = true everything is OK when it is gCSVHeader = false and compilation fails. Thanx for any advice Jaroslav Hajtmar Here is my minimal version of problematic example: % csvfile.txt content: % first,second,third,fourth % 1,"2","3","4" % "a","b","c","d" % "foo","bar""baz","boogie","xyzzy" % \starttext \startluacode --gCSVHeader=true -- works fine when compiled any version of ConTeXt gCSVHeader=false -- crashed, when compiled by last beta version of standalone gColNames={} gColumnNames={} local inpcsvfile='csvfile.txt' local currentlyprocessedcsvfile = io.loaddata(inpcsvfile) local mycsvsplitter = utilities.parsers.rfc4180splitter{ separator = ',', quote = '"', } if gCSVHeader then gTableRows, gColumnNames = mycsvsplitter(currentlyprocessedcsvfile,true) inspect(gTableRows) inspect(gColumnNames) for i=1,#gTableRows[1] do gColNames[tostring(gColumnNames[i])] = i -- for indexing use end else gTableRows = mycsvsplitter(currentlyprocessedcsvfile) inspect(gTableRows) -- ad now set column names for withoutheader situation: for i=1,#gTableRows[1] do context(gTableRows[i]) gColumnNames[i]='c'..(i) end end gNumRows=#gTableRows -- Getting number of rows gNumCols=#gTableRows[1] -- Getting number of columns context.setgvalue("numrows",tostring(gNumRows)) context.setgvalue("numcols",tostring(gNumCols)) context.setgvalue("filename",tostring(inpcsvfile)) \stopluacode File \filename\ has \numrows\ lines and \numcols\ columns. \stoptext

TikZ and wrong drawing order
by Mojca Miklavec 15 Jun '15

15 Jun '15

Hi, I would like to ask for help for either finding a fix or some clever workaround for the following problem. If I use a TikZ picture as item symbol and additionally use background text, then the first symbol in itemize environment gets covered by the background. Here's an example: \usemodule [tikz] \definesymbol[1] [{\tikz\shade[shading=ball,ball color=blue] (0,0) circle (.2cm);}] \definecolor [backcol] [s=1,a=1,t=0.1] \starttext \startframedtext[width=4cm,background=color,backgroundcolor=backcol] \startitemize \item one \item two \item three \stopitemize \stopframedtext \stoptext Thank you, Mojca

new beta
by Hans Hagen 15 Jun '15

15 Jun '15

Hi, I uploaded a beta. The most significant (visible) change is in the way mp handles outlines. Here are some examples: % outlinetext (text) transformations ; % outlinetext.d (text) (draw options) transformations ; % outlinetext.f (text) (fill options) transformations ; % outlinetext.b (text) (draw options) (fill options) transformations ; % outlinetext.r (text) (fill options) (draw options) transformations ; \starttext \startMPpage draw outlinetext.b ("\framed[align=normal]{\input{tufte}}") (withcolor .5white) (withcolor red withpen pencircle scaled 1/10) xsized 10cm ; \stopMPpage \startMPpage draw outlinetext.r ("\framed[align=normal]{\input{tufte}}") (withcolor red withpen pencircle scaled 1/10) (withcolor .5white) xsized 10cm ; \stopMPpage \startMPpage draw outlinetext.d ("\framed[align=normal]{\input{tufte}}") (withcolor .5white) xsized 10cm ; \stopMPpage \startMPpage picture p ; p := outlinetext.p("PX") ; for i within p : draw i withcolor red withpen pencircle scaled 1/10 ; endfor ; \stopMPpage \stoptext If you say (will b edefault when no complaints): \startMPdefinitions let graphictext = new_graphictext ; \stopMPdefinitions the graphictext macro will also use this method. If you want a nice view on a font you can say: \useMPlibrary[outlines] \showshape[character=a,alternative=page] \stoptext or for a whole font: \setupbodyfont[pagella] \showshape[character=all,alternative=page] or \definedfont[almfixed] \showshape[character=all,alternative=page] Another change is a much faster reload of fonts database but as that doesn't happen often it might go unnoticed.

selecting font by (file) name
by Pablo Rodriguez 13 Jun '15

13 Jun '15

Dear list, I have the following sample: \definefontfamily [mainface] [rm] [TeX Gyre Pagella] \definefontfamily [mainface] [tt] %~ [file:lmmonoproplt10-regular.otf] [name:lmmonoproplt10regular] \setupbodyfont [mainface] \starttext \type{monospace font} \stoptext Either by file or name, I’m not able to select the font. I get the following list from mtxrunjit: $ mtxrunjit --script font --list --file --pattern=lmmonoproplt10regular latinmodernmonoproplight light normal normal normal lmmonoproplt10regular lmmonoproplt10-regular.otf What am I doing wrong here? Many thanks for your help, Pablo -- http://www.ousia.tk
