m-steps on mkiv
by DesdeChaves 28 Jan '14

28 Jan '14

Some features of m-steps does not work in mkiv. For example, I can not change colors and the shapes (first example), add steps from the cell (n) to the cell (n+m, m=2,3,4...) and reverse steps. \usemodule[steps,mathml] \starttext \startSTEPtable \setupSTEPcells [alternative=5, framecolor=red] \setupSTEPtexts [framecolor=green] \setupSTEPlines [alternative=5] \cell {initial concentration, $C_i$} \text {$\div C_f$, final concentration} \cell {diluation factor, $f$} \text {inverse} \cell {$\frac{1}{f}$} \text {$\times V_f$, volume of the volumetric flask} \cell {pipette volume, $V_p$} \stopSTEPtable >From the manual: \startSTEPchart \cell {A} \cell {one} \texts{}{+2} \texts{}{+3} \cell {two} \cell {three} \texts{+4}{} \texts{+5}{} \cell {four} \cell {five} \stopSTEPchart \stoptext Jorge

special case to disable italic correction
by Pablo Rodriguez 28 Jan '14

28 Jan '14

Hi Hans, after reading the relevant part for italic correction in fonts-mkiv.pdf and enabling it in my documents, I have found a case in which the italic correction could be improved. My settings are: \definefontfeature[default][default][itlc=yes] \setupitaliccorrection[global,always] If I get it right, the italic correction should be avoided before points and commas (these are all the exceptions I can imagine for this case). The explanation is simple: the space is already at the base line, since at the glyph base, the inclination of the italic or slanted glyph makes the right side-bearing larger at the baseline. The issue with italic correction is mainly with ascenders or at the cap height, but I think it isn’t at the base line (or the descenders). Because of that I think it is important to disable italic correction before points and commas. The sample shows the issue: \setuppagenumbering[location=] \definefontfeature[default][default][itlc=yes] \setupitaliccorrection[global,always] \starttext \startTEXpage[offset=1ex] Abf. {\em Abf}.\\ Abf, {\em Abf},\\ Abf. {\it Abf}.\\ Abf, {\it Abf}, \stopTEXpage \stoptext I think it might be worth considering. Many thanks for your help and your excellent work, Pablo -- http://www.ousia.tk

definefontfamily options for caps and capsbold fonts
by Pablo Rodriguez 27 Jan '14

27 Jan '14

Hi Wolfgang, with the new simplefonts interface I have two options that used to work with the old interface, but that don’t work now. Here is the command: \definefontfamily[mainface][mono][ryt1xtt][capsfont=ryt1xttsc, boldfont=ryt1xbtt, capsboldfont=ryt1xttsc] I get mono the bold font, but I cannot get mono small caps or mono bold small caps. Is alternative=simplefonts the right way to make them work? (They work fine with this option, but I have the impression of using old code.) Many thanks for your help, Pablo -- http://www.ousia.tk

runtime problem with metafun() code
by Peter Rolf 27 Jan '14

27 Jan '14

Hi, I try to create a Metapost path in lua and it works so far for the attached example. But a call of that function from another lua function sadly fails (no path visible after call). The code seems to be executed later (the output from 'show pid;' appears somewhere later in the log). How can I ensure that the code is executed at runtime? Peter

Change the default text colour for entire document
by Thangalin 27 Jan '14

27 Jan '14

Hi, In ConTeXt to change the default text colour for the entire document, there are at least two settings that need to be configured: \setupcolors[textcolor=red] \setupinmargin[line=13,color=red,style=slanted,] The border colour for tables remains black: \setupcolors[textcolor=red] \setupinmargin[color=red] \starttext {\bTABLE \bTR \bTD One \eTD \bTD Two \eTD \eTR \eTABLE} \stoptext How can you override *all* instances of black? (Ideally there would be a single setting that is inherited by all.) That is, it is difficult to know all the various aspects of a ConTeXt document that use the default black colour -- margins, body text, table borders, and possibly more that I don't know about. Thank you!

Does that mean that > url can actually used as a data field name? > Hi, I have struggled with Bibliographies and almost gave up, because of the non-standard, and changing, style requirements (like apa but different in details, with, moreover, three different styles for citations in footnotes: full data, a shorter version and a still shorter version, the latter probably (authoryear), but I'm still not sure). In the end I used for everything the category "booklet", which is less of a straitjacket than the other categories. It gives you the freedom to put some extra details (if needed) in the title and also to style the "author" the way you want (for example Last name, First name or Last name, initials, or Initials Last name or whatever you want.) You can also use urls there, as far as I know. For consistency you would still need a bibl style file, for which I used a tweaked version of bibl-apa.tex. (which is in ~/<context-minimal>/tex/texmf-context/tex/context/bib) And a last thing: I input not the BibTeX database but the .bbl which I generate separately. I can tweak that if necessary or to add specific features, like horizontal lines in the Bibliography for repeated author names. (Another requirement which I personally don't like). Maybe all this is rather unworthy of ConTeXt but it is comparatively easy to accomplish and it works. I hope it helps. Best regards, Robert Blackstone

Simpleton bibliography
by john Culleton 26 Jan '14

26 Jan '14

A very recent (Jan 21) wiki article lists this example for a simple bibliography: ----------------------------- \usebtxdataset [mybibfile.bib] \setupbtxrendering [numbering=yes] --------------------------------- Now that is simple enough for starters. Question 1: What are the other options for \setupbtxrendering and what do they do? (In my world Bibliographies are seldom numbered.) Question 2: Suppose I want to follow a different standard, other than APA, such as harvard or Chicago or whatever: where do I code that choice and how? Are bst files still in play? Question 3: url is mentioned. Does that mean that url can actually used as a data field name? I am of the KISS persuasion (Keep It Simple Silly). All of furbelows and feathers that fascinate real experts are not my cup of code. Bless the real experts, without them there would be no TeX or Context, but I am not of their clan. All I want to do is: A: Create a list of books properly encoded in bibtex or similar style. Probably all the entries will be @book types. B: print items out of that list as I choose them with \cite or \nocite in a backmatter chapter called "references" or "bibliography". -- John Culleton Wexford Press Free list of books for self-publishers: http://wexfordpress.net/shortlist.html PDF e-book: "Create Book Covers with Scribus" available at http://www.booklocker.com/books/4055.html

fallback font in new interface to simplefonts
by Pablo Rodriguez 25 Jan '14

Dear list, the following code doesn’t find the fallback font for Hebrew: \definefallbackfamily[mainface][serif][FreeMono-Bold][range={hebrew, alphabeticpresentationforms}, force=yes] \definefontfamily[mainface][serif][TeX Gyre Pagella] \setupbodyfont[mainface] \starttext ץ׃. \stoptext But the same font works with the old interface: \usemodule[simplefonts] \setmainfontfallback[FreeMono-Bold][range={hebrew, alphabeticpresentationforms}, force=yes] \setmainfont[TeX Gyre Pagella] \starttext ץ׃. \stoptext Am I doing something wrong here?
