Re: [NTG-context] Using Postscript Type 1 fonts in ConTeXt/XeTeX?
by Roland 04 Mar '08

04 Mar '08

Seems we never posted the conclusion about this problem: XeTeX simply doesn't work with the old Mac Type 1 Postscript fonts on Mac OS X (Leopard or before). The reason is that these old fonts store their data in the resource fork, which Unix utilities like XeTeX don't see. Only TrueType or OpenType fonts will be recognised and loaded correctly. PCs don't have the data fork so old Type 1 Postscript fonts for PCs (with .pfb extension) seem to work. Just copying these to the Mac is no solution, however, because Mac OS X does not support PC-style Type 1 fonts (only the Mac ones with the data in the resource fork), and therefore XeTeX will not find these fonts. Therefore the preferred solution is to use fonts of TrueType or OpenType varieties. For those with access to a font conversion program like fondu (?) fontforge (?) or fontlab (?) it may be possible to convert the old Type 1 font to TrueType or OpenType, reinstall it and have XeTeX work with it in that way.

Background color spaning columns.
by Bart Wise 03 Mar '08

03 Mar '08

I am trying change the background color of some text. It works fine if I am using one column. It also works fine if I am using multiple columns, but restricting my background color changes to only a single line of text in a column. However, if I have a section that I want to I change, and that section spans more than one line in a given column it does not work. What happens is that the background starts to change where you have indicated; however, instead of stopping at the end of the column, the background color changes for the entire text. See the subject entitled "Problem 1" below for an example. Is there a fix for this (and no, using a single column is not a solution.) Problem #2 is the same thing only the background change starts in the first column and extends to the second. In this case the output is even worse. It's difficult to describe, so run the code. Solutions? Thanks, Bart ******************************* * Sample Code --- #1 ******************************* \setupcolors[state=start] \definetextbackground[highlight][ backgroundcolor=yellow, frame=off, location=text, color=black] \definestartstop[Highlight][ before={\starttextbackground[highlight]}, after=\stoptextbackground] \starttext \subject{Problem 1} \startcolumns It was a· \starthighlight dark· and stormy night; the rain fell in torrents --- except at occasional intervals, when it was checked by a· violent\stoptextbackground~ gust of wind which swept up the streets (for it is in London that our scene lies), rattling along the housetops, and fiercely agitating the scanty flame of the lamps that struggled against the darkness. \stopcolumns \subject{Problem 2} \startcolumns It was a dark and stormy night; the rain fell in torrents --- except at occasional intervals, when it was checked by a violent gust of wind which· \starthighlight· swept up the streets (for it is in London that our scene lies), rattling along the housetops, and fiercely agitating the scanty flame \stophighlight of the lamps that struggled against the darkness. \stopcolumns \stoptext

multiple pattern with xmltools.rb
by Peter Rolf 03 Mar '08

03 Mar '08

Hi, I tried several variants to use multiple pattern with xmltool. None of them worked and looking in the script didn't help either (me_no_ruby). A (not working) example: xmltools.rb --dir --pattern={*.png,*.jpg} --output=filelist.xml I need the filelist as base for the creation of a resource library (xml part), so multiple pattern support is a prerequisite here.

problem with startitemize and columns option
by mikael MAUNIER 03 Mar '08

03 Mar '08

hi, I am trying to migrate from latex to context and i would like to create an enumeration using this minimal example : ---------------- \startitemize[m,joinedup] \item\startitemize[a,columns,three] \item test 1 \item test 2 \item test 3 \stopitemize \item \startitemize[a,joinedup] \item test 4 \item test 5 \item test 6 \stopitemize \stopitemize ------------------ You can see that test 4 to test 6 are well-aligned with the item number 2 Unfortunately, the test 1 to test 3 are not because of the columns option. I tried to find a solution in all doc on the wiki, but could'nt managed to put test 1 just in front of item 1 ... Somebody can help ? thanks mikael PS : sorry for my english ;-) _____________________________________________________________________________ Ne gardez plus qu'une seule adresse mail !

hz and protrusion
by Hans Hagen 03 Mar '08

03 Mar '08

Hi, The latest luatex beta + mkiv support hz and protruding. The user interface will be extended a bit, but for the moment it goes as follows: % engine=luatex % \setupfontexpansion [quality][stretch=2.5,shrink=2.5,step=.5,factor=1] \setupfontexpansion[oeps][a=1,b=2] \setuptolerance[verytolerant,stretch] \showframe \starttext \definefontfeature[demo][default][mode=node,expansion=quality,protrusion=pure] \start \definedfont[Serif*demo at 12pt] \enableadjusting \enableprotruding \input tufte \par %\definedfont[name:optimanova*demo at 12pt] \enableadjusting \enableprotruding \input tufte \par \stop \stoptext (or the usual \setupalign options) As you may deduce from this example, handling is gone in mkiv. This not only safes some 40K format file, but the new mechanism also runs faster (some 10% overhead on 300 pages of pure text, which is rare). At some point we need to extend the hz/protruding vectors in mkiv to cover non latin scripts as well (currently they default to factors of 1). As with mkiv, latin glyphs fall back to their shape parent. Under some circumstances hz may not work as expected. Fixing this is on the agenda for the next luatex beta release.

new mkiv beta
by Hans Hagen 02 Mar '08

02 Mar '08

Hi, I uploaded a beta release. The biggest change is that image inclusion in mkiv has changed. Currently it's still some mix of tex and lua code, and the backend code is somewhat messy (and not complete yet) but it's a first step towards lua doing things. This will only work with a e recent luatex. The advantage is that file searching in lua is more robust (and when many search paths are used, also faster). Image conversion has been moved to lua too, but currently still uses pdftops (also for svg) but that may move to lua as well. Figure libraries are supported by default now.

Two questions about use of system ttf fonts
by weg＠indiscrete.org 02 Mar '08

02 Mar '08

Hi, I am trying to use truetype fonts with mkiv. When loading a font given a full path name like this: \font\test=/usr/share/fonts/truetype/freefont/FreeSans.ttf at 12pt the log shows report >> load otf: loading: /usr/share/fonts/truetype/freefont//FreeSans.ttf report >> load otf: enhance: before report >> load otf: enhance: enrich report >> load otf: enhance: registering tlig feature report >> load otf: enhance: registering trep feature report >> load otf: enhance: flatten report >> load otf: flattening 'specifications' tables report >> load otf: flattening 'anchor' tables report >> load otf: flattening 'gpos' tables report >> load otf: flattening 'gsub' tables report >> load otf: enhance: analyze report >> load otf: enhance: after report >> load otf: replacing 'kerns' tables by 'mykerns' tables report >> load otf: enhance: patch report >> load otf: enhance: strip report >> load otf: enhance: pack report >> load otf: file size: 458648 report >> load otf: saving: in cache fonts : resetting map file list {/usr/local/share/texmf/fonts/map/pdftex/context/original-empty.map} fonts : using map file: original-base {/usr/local/share/texmf/fonts/map/pdftex/context/original-base.map} fonts : using map file: lm-math {/usr/share/texmf/fonts/map/dvips/lm/lm-math.map} fonts : using map file: lm-rm {/usr/share/texmf/fonts/map/dvips/lm/lm-rm.map} fonts : using map file: original-ams-base {/usr/local/share/texmf/fonts/map/pdftex/context/original-ams-base.map} fonts : using map file: original-ams-euler {/usr/local/share/texmf/fonts/map/pdftex/context/original-ams-euler.map} fonts : using map file: original-public-lm {/usr/local/share/texmf/fonts/map/pdftex/context/original-public-lm.map} [1.1] systems : end file 11 at line 24 ) !luaTeX error (file FreeSans.ttf): cannot open OpenType font file for reading ==> Fatal error occurred, no output PDF file produced! How can I tell what's wrong? Defining \font\test=FreeSans.ttf at 12pt results in error >> define font: font with name FreeSans is not found error >> define font: name: FreeSans, loading aborted ! Font \test=FreeSans at 12pt not loadable: metric data not found or bad. while using this construction with luatex's plain format seems to work (I assume some definition to register the font). What does context need to find the font? Thanks, Eythan

ConTeXt XSLT plugin for MultiMarkdown> anyone know XSLT?
by Roland 01 Mar '08

01 Mar '08

Hi, I have been experimenting with using standard text formats like Markdown and Multimarkdown to produce texts for multiple outputs (HTML, RTF, ConTeXt etc) The basic Markdown syntax is quite limiting; but unfortunately, the more advanced MultiMarkdown syntax does not yet have an XSLT translator available for ConTeXt. It seems that creating one is simple, but that the author needs people with more understanding of ConTeXt syntax than he has. See my request on the MultiMarkdown website http://fletcherpenney.net/Comments_on_Feature_Requests[copied below]. Anyone on the mailing list have enough understanding of XSLT and ConTeXt to help out with creating such a translator? Like the Pandoc converter, it would help to promote ConTeXt towards a broader audience... Thanks Roland Would it be difficult to also create an XSLT file for output to ConTeXt? I know it's not used as much as LaTeX but given the focus on highly customisable ouput, I find it more suitable to writing and publishing needs than LaTeX. Also, the syntax seems more consistent, therefore an XSLT file might not be all that hard to produce? There is some more info on http://tex.loria.fr/formats/context/LaTeX2ConTeXt.pdf and on http://wiki.contextgarden.net/From_LaTeX_to_ConTeXt Pandoc (an alternative for converting Markdown documents into various formats) already has ConTeXt support built in but unfortunately it does not allow multimarkdown syntax… – siros 2008-02-24 15:57 An XSLT setup can be made for any TeX derivative, since they all rely on a plain text document format. I am not too familiar with the ConTeX syntax, but I suspect most of it would be quite similar to LaTeX, and that the preamble stuff would be the biggest changes. – Fletcher Penney 2008-02-25 22:55
