[Tools] v1.1 of ConTeXt BBLM for BBEdit
by Paul Mazaitis 21 Jul '15

21 Jul '15

I've released a version of the ConTeXt BBLM that better manages files referenced by environment or project structure commands. The language module populates the BBEdit Includes Menu with files referenced by: \environment \project \product \component The language module begins looking for any file matches in the parent directory, and then searches recursively downward in the file system for any matching files. Available here: https://github.com/pmazaitis/ConTeXtBBLM/releases/tag/v1.1.0 Thanks! -Paul

Temporary spacing between letters
by Procházka Lukáš Ing. - Pontex s. r. o. 20 Jul '15

20 Jul '15

Hello, is it possible to affect the space between letters temporarily? The following code provides it, but I guess there is a better ConTeX way: ---- \starttext \startluacode t = function(str, filler) return str:gsub("(.)", "%1" .. (filler or "~"), #str - 1) end \stopluacode Doslov\par \cldcontext{t("Doslov", "\\,")}\par \cldcontext{t("Doslov", "\\;")}\par \cldcontext{t("Doslov")}\par \cldcontext{t("Doslov", "~~")}\par \cldcontext{t("Doslov", "\\quad ")}\par \cldcontext{t("Doslov", "\\qquad ")}\par \stoptext ---- Best regards, Lukas -- Ing.

User-Defined Commands With Key-Value Options

Is the data stored in lua?*Yes, I imagine that the data (for instance, the value of the keys "number", "name", "abbreviation", "title", etc.) is stored somewhere when the compilation process reads, say, "\startbiblebook", and that they are available to define the the formatting done by "\startbiblebook". Thank you.

User-Defined Commands With Key-Value Options
by Joas Yannick 19 Jul '15

19 Jul '15

Dear everyone, I am currently typesetting the old (published in 1707) French Bible of David Martin using ConTeXt MkIV. The source code looks like this: \startproduct martin1707 \startproject bibles % Page layout, fonts, language, etc. \startbiblebook[number={1}, name={Genéſe}, abbreviation={Gen.}, title={Le premier livre de Moyſe dit la Genéſe}] \startbiblechapter[number={1}] \startbibleverse[number={1}] Au commencement Dieu créa les cieux & la terre. \stopbibleverse \stopbiblechapter \stopbiblebook \startbiblebook[number={45}, name={Romains}, abbreviation={Rom.}, title={Epiſtre de ſaint Paul apoſtre aux romains}] \startbiblechapter[number={12}] \startbibleverse[number={1}] Je vous exhorte donc, \bibleaddition{mes} fréres, par les compaſſions de Dieu, que vous préſentiez vos corps en ſacrifice vivant, ſaint, agréable à Dieu, \bibleaddition{qui eſt} vôtre raiſonnable ſervice. \stopbibleverse \startbibleverse[number={2}] Et ne vous conformez point à ce préſent ſiecle, mais ſoyez transformez par le renouvellement de vôtre entendement, afin que vous éprouviez quelle eſt la volonté de Dieu, bonne, & agréable, & parfaite. \stopbibleverse \stopbiblechapter \stopbiblebook \stopproduct As you may know, all the Bibles are divided into books, and each book into chapters, and each chapter into verses. The purpose of \startbiblebook, \startbiblechapter, and \startbibleverse is to control the formatting thereof respectively (as \startsection, \startsubsection, etc., control the formatting of sections, subsections, etc.) Now, as you see. these commands are user-defined commands with key-value options. My goal is to define the way they do the formatting with Lua. But I do not know how to do. I know a bit about programming, so learning Lua is not a problem. Thanking you in advance, All the best, Yours faithfully.

em-/en-dashes and newotf

Hans, with the following sample: \usemodule[newotf] %~ \setupbodyfont %~ [palatino] \starttext --- em--dash (with en--dash inside) \stoptext I discovered that em- and en-dashes aren’t enabled by default. Is this intended? Many thanks for your help, Pablo -- http://www.ousia.tk

As you see, theses commands are user-defined and take key-value options. My goal is to define their semantics (the way they do the formatting) with Lua. But I do not knwo how to do this. I know a bit about programming, and learning Lua is not a problem for me. Thanking you in advance, All the best.

SyncTeX (TeXworks) - \enabledirectives[system.synctex]
by Procházka Lukáš Ing. - Pontex s. r. o. 18 Jul '15

18 Jul '15

Hello, two questions related to SyncTeX (and maybe on TeXworks): 1. The following code: ---- \enabledirectives[system.synctex] \starttext Hello! \startluacode % line 6 context("Something") \stopluacode \stoptext ---- doesn't produce SyncTeX file (SyncTeX.synctex.gz). When I compile the file with "context.exe --synctex" option, the file is produced. Does it mean that "\enabledirectives[system.synctex]" is deprecated? 2. In the code above, text "Hello!" is generated in "normal TeX scope" whilst "Something" is generated from within Lua. When I click "Jump to source" from TeXworks editor and previewer, jumping from "Something" works well and goes to the source "SyncTeX.mkiv" correctly. "Jumping to source" from "Something" yields "Cannot read file <directory-of-the-source-file>" error (see attached picture). I don't know whether this relates to ConTeXt or rather TeXworks; for the case it should relate to ConTeXt, would it be possible generate an anchor (e.g.) to the nearest encapsulating \startluacode (if present; or \ctxlua, \cldcontext and so), so that "Jump to source" over "Something" would jump to \startluacode on "line 6"?

Math - how to mix fonts?
by Procházka Lukáš Ing. - Pontex s. r. o. 18 Jul '15

18 Jul '15

Hello, I am not very familiar with mixing fonts in math. I would need to mix several font styles: 1. "normal" (default - slanted, serif) for general variables, 2. slanted serif bold for vectors, 3. slanted sans bold for varieties. In the following snippet, the right fonts are displayed in the \text scope, but not in the math: ---- \definetypeface[boldmath][mm][boldmath][latin-modern][default] \starttext \startformula \text{\sl 1. Normal:}\quad Abcd \alpha \stopformula \startformula \text{\bs 2. Bold:}\quad\boldmath{Abcd \alpha} \stopformula \startformula \text{\bs\ss 3. SansBold:}\quad\ss\boldmath{Abcd \alpha} \stopformula \stoptext ---- You can see that \boldmath has no effect (although "\definetypeface[boldmath][mm][boldmath][latin-modern][default]" was used, as described on http://wiki.contextgarden.net/Bold_Math ). So - what is the best way to define (enable) and use fonts styles 1.-3. in math? ( Notes: - The font must allow to type Greek letters - \alpha. - Other font(s) than LatinModern may be used for math, if it enables bold and sans switching. ) Best regards, Lukas -- Ing.

What is a better way to do this macro?
by Idris Samawi Hamid ادريس سماوي ح امد 17 Jul '15

17 Jul '15

Dear gang, Consider the following (also attached): =====choice-cs.tex==== \def\CHOICE#1#2{\leavevmode\vbox{\tabskip=0pt\everycr={} \halign{\strut\hfil##\hfil\cr#1\cr#2\cr}}} \setuppagenumber[state=stop] \setupwhitespace[big] \starttext (One~* Two~* Three~* Four) is even. (\CHOICE{x}{One}~* \CHOICE{1}{Two}~* \CHOICE{x}{Three}~* \CHOICE{2}{Four}) is even. \stoptext ====================== What is best way to define the \CHOICE macro without low-level TeX commands, only high-level ConTeXt commands? Thanks in advance and Best wishes Idris -- Idris Samawi Hamid Professor of Philosophy Colorado State University Fort Collins, CO 80523

But my question asked where are the config files : I want to get a Python pretty-printing. The module abr-01 seems the key but I couldn't find it. It seems that the answer could be in the t-vim (third party) module. It uses the syntax analysis from VIm (you have to install it :)) -- Eric Détrez Informatique Lycée Faidherbe, Lille http://eric-detrez.fr
