Inserting verbatim text in a figure and framed.
by john Culleton 31 Jul '13

31 Jul '13

Here is my code so far. I want to show a file in verbatim form. It compiles but here is no frame around the text and there is no caption. ---------------------------- \startbuffer[ex1] \typefile[]{example1.tex} \stopbuffer \placefigure[here][fig:ex1] {Example 1} {\externalfigure[ex1.buffer][width=.75\textwidth]} -------------------------------------------------- I am following the example at the foot of page 303 in the manual. Any suggestions? John Culleton

Math fallback
by Aditya Mahajan 31 Jul '13

31 Jul '13

Is it possible to use the fallback mechanism for math fonts? For example, I am using Neo Euler for math which has a few missing glyphs. Can I use Cambria (or Xits) as a fallback font for missing glyphs. I am using the simplefonts module, but I am happy to write a typescript file if that makes things easier. I do not really want to define a new virtual font. Aditya

Left-justifying the date in the letter module
by Michael Ash 31 Jul '13

31 Jul '13

I am still having a problem with left-justifying the date in letters. The date is towards the left but is aligned several mm to the right of the other text. \usemodule[letter] %% Omit the word "Date", attempt to left-justify date (doesn't align perfectly) \setupletterlayer[reference][alternative=c] \defineletterelement[layer][address][example]{\correspondenceparameter{toname}\par} \setupletterlayer[address][alternative=example] \starttext \startletter[ toname={The Addressee}, opening={Dear Addressee:}, closing={Best regards,}, signature={I.M. Sender}] \input knuth \stopletter \stoptext BTW are the values for the "alternative" key ("example", "e", "c", etc.) documented somewhere? Thank you again. Best, Michael

Change URL color to match layer
by Michael Ash 30 Jul '13

30 Jul '13

I would like to change the color of URL's in parts of a document. In particular I am using the letter module and would like to have the color of URL's match the color of text in the letterhead and then change to match the color in the main body of the letter. I can set the URL color once with \setupinteraction but I do not see how to change it thereafter. Thank you very much for your guidance. Best, Michael \usemodule[letter] \setupinteraction[state=start,color=black] %% \setupinteraction[state=start,color=red] %% Would like this URL to match the color of the return address ("location") \useURL[author-email][mailto:mash@econs.umass.edu][][mash@econs.umass.edu] %% Would like this URL to match the color of the recipient's address ("address") \useURL[recipient-email][mailto:addressee@gmail.com][][addressee@gmail.com] %% Would like this URL to match the color of the main body \useURL[knuthbio][ http://en.wikipedia.org/wiki/Donald_Knuth][][http://en.wikipedia.org/wiki/D… ] \setupletter[ name={Michael Ash}, email={\from[author-email]} ] \setupletter[signature={Michael Ash}] \defineletterelement[layer][location][example]{\correspondenceparameter{name} \correspondenceparameter{email}\par} \setupletterlayer[location][alternative=example,color=red] \defineletterelement[layer][address][example]{\correspondenceparameter{toname}\par} \setupletterlayer[address][alternative=example,color=blue] \starttext \startletter[ toname={The Addressee\\\from[recipient-email]}, opening={Dear Addressee:}, closing={Best regards,}] Enjoy \from[knuthbio] \stopletter \stoptext

Questions about mathfence
by Aditya Mahajan 30 Jul '13

30 Jul '13

Hi, Some questions/remarks about math fences 1. When using \definemathfence[colorbracket][bar][middle=0x7C,color=red, command=yes] \starttext \startformula \colorbracket{\frac {a}{b}\fence a = b}^n \stopformula \stoptext The delimiter is of the wrong color (black instead of red), and the clause after \fence is red. I am doing something wrong or is it a bug. 2. For some types of expressions, for example, probability, the middle delimiter should have the space similar to mathrel, rather than mathord. For example, while typing I often use: \Pr\left( X = \frac {a}{b} \,\middle|\, Y = \frac{c}{d} \right) Would it be worthwhile to add these extra spaces by default (not sure what is the convention in physics/quantum mechanics for bra and ket notation) or as an option. 3. Finally, why are the default values of left, middle, and right = 0x2E. Isn't 0x7C a better default? Thanks, Aditya

Using backslash in chapter title.
by john Culleton 28 Jul '13

28 Jul '13

Using MKIV and MyriadProBold for my sanserif font I have the following chapter title: "Can You Type \bye?" which I type as \chapter{Can You type \backslash bye?} The slash appears but a bit low and much too thin. I have tried various games including creating a special font just for this character but nothing changes. the \backslash command seems invulnerable to change. Is there a way in MKIV to express a backslash in another way (bigger and bolder)? John Culleton

OSFONTDIR kills gui fonts.
by john Culleton 28 Jul '13

28 Jul '13

I am tryihg to follow the wiki on "Fonts in Luatex." It suggests the following statement for Linux systems: export OSFONTDIR="/usr/local/share/fonts;$HOME/.fonts" But I store my fonts in /usr/share/fonts so I used: export OSFONTDIR="/usr/share/fonts" The net effect of this statement was to wipe out all my text fonts used with XFCE4 or KDE, at least when I use my regular user signon. I examined my /etc/profile, $HOME/.profile, @HOME/.bashrc files and deleted or commented out all references to OSFONTDIR. I still have no gui fonts. If anyone has any suggestions on how I can revive my gui fonts that would be welcome. Only my regular user signon is affected, But I really want to know what kind of OSFONTDIR statement I can use that won't wipe out my gui fonts. I can of course move the pertinent fonts to the fonts directories in my /usr/local/texlive etc. file structure. But I am looking for a more general solution. Slackware 14 64 bit and texlive 2013 As always, thanks in advance to those who reply: John Culleton

Opening quotes problem with context.
by john Culleton 27 Jul '13

27 Jul '13

Did a fresh install of context etc. from the context site. I used this test file: ------------------------------- \starttext ``Hello world.'' And ``Goodbye world.'' \stoptext %\bye ----------------------------------------- The resulting pdf shows two left tick marks for opening quotes but the closing quotes are proper curly quotes. If I modify the file as follows: ------------------------------- %\starttext ``Hello world.'' And ``Goodbye world.'' %\stoptext \bye --------------------------- and use luatex or pdftex from texlive the quotes are OK. I got similar results from context in texlive 2012 and texlive 2013. What is the proper code for opening quotes in context? I use slackware linux 14, the 64 bit version. -- 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

bug in \type?
by Pablo Rodríguez 27 Jul '13

27 Jul '13

Dear list, using the latest beta (it also happens with ConTeXt from TL 2013), I don’t get the space in \type{\em #1}. Here you have a minimal sample that shows the difference with other verbatim commands: \starttext \type{\em #1} \arg{\em #1} \starttyping\em #1\stoptyping \stoptext Is this a bug in \type or am I missing something? Many thanks for your help, Pablo -- http://www.ousia.tk
