Replace + V(ltgtstring) by -- + V(ltgtstring) at L175 of 
t-pretty-c.lua as a temporary workaround…

Re: [NTG-context] [OT] − RobotoSlab Italics… or not

[Renaud Aubin]

Hi Hans,

Thank you for the review and your suggestions!

Le 24/11/2013 12:53, Hans Hagen a écrit :

 normally typescripts like that end up in tex/context/third (maybe at
 some point we can collect extra typescripts in one package)

https://github.com/nibua-r/roboto-context/issues/1

Extra typescripts collection is a good idea. I have at least some
typescripts here for Minion, Meta, frutiger, …
Any other contributed typescripts are welcome!


 a few suggestions:

 \definefontfeature[slanted][default][mode=base,slant=.25]

 best define roboto-slanted as you don't want to overload other
 definitions of slanted and this is rather font specific .. and are you
 sure you want base mode here?

https://github.com/nibua-r/roboto-context/issues/2


 \definefontfeature[roboto-slanted][slant=.25]

 \definefontsynonym [\s!SerifItalic] [\s!Serif]
 [\s!features={default,roboto-slanted}]

 should also work and delays default

RobotoSlab doesn't get slanted without mode=base and/or
features={default,roboto-slanted}. I can't explain why but maybe
Wolfgang could explain since he is the one who provided the solution in
the first place.

https://github.com/nibua-r/roboto-context/issues/3
https://github.com/nibua-r/roboto-context/issues/4


 also, name type typescript type-imp-roboto.tex (or .mkiv)

 Hi folks,

 I'm working on a Roboto typescript and starting from the work done by
 Zen Lima back in last July, I would like to push things further.
 Since I work on some Android projects and use Google Keep mostly on a
 daily basis, I was surprised to not find italics for the RobotoSlab
 (either on the web or by extracting the assets of the Keep package).

 Why am I surprised: Keep do have serif title placeholders for the new
 note EditText and I see it everyday!

 $ mtxrun --script font --list --all --pattern=robotoslab

 robotoslab  robotoslabbold  RobotoSlab-Bold.ttf
 robotoslabbold  robotoslabbold  RobotoSlab-Bold.ttf
 robotoslablight robotoslablight RobotoSlab-Light.ttf
 robotoslabregular   robotoslabregular   RobotoSlab-Regular.ttf
 robotoslabthin  robotoslabthin  RobotoSlab-Thin.ttf

 OK, RobotoSlab fonts are accessible and I have a working typescript to
 use RobotoSlab with ConTeXt MkIV (I'll made the git repo public soon).
 At first, my thoughts are: nevermind the Slab italics but now, I'm
 curious since Inkscape, LibreOffice, … propose the italic and bolditalic
 features of the RobotoSlab (check out the attached font-manager screenshot).
 I've worked with different kind of fonts'family (more or less complete)
 and used and modified many typescripts in my ConTeXter's life but there
 I should be missing something obvious. Where are the RobotoSlab
 Italics??? My experience is that italic and bolditalic should correspond
 to files… First guess: no files so the RobotoSlab Italic and BoldItalic
 features are just faked ones composed by my GNU/Linux Debian system. No,
 I must be wrong here too…

 Any thoughts on The Quest of the Hidden Italics of the RobotoSlab fonts!“?

 The font has no italic but inkscape slants the regular and bold styles to get 
 them,
 you can do the same in context with the slant key from \definefontfeature.

 \definefontfeature[slanted][default][mode=base,slant=.25]

 \definefontfamily[roboto][rm][Roboto 
 Slab][it=features:slanted,bi=features:slanted]

 \setupbodyfont[roboto]

 \starttext
 Regular {\it Italic} {\bf Bold} {\bi BoldItalic}
 \stoptext

 No, it shouldn't, because it doesn't work with latest ConTeXt versions.

 You could also try

 but I don't know, if it works with latest ConTeXt.

Fortunately  my c-pretty-printer package does work with a recent (i.e.

 Hi,

 I uploaded a new beta. The most important changes are:

 - Environments and modules are no longer loaded under protection so
 this has to be done explicitly in the files themselves. So far we
 haven't encountered problems with that change.

 - Some more cont-*.tex files have been split in mkii and mkiv
 versions. In mkii a tex file is loaded when no mkii file is found, but
 in mkiv only files with suffix mkiv are loaded. That way we stay
 compatible. This also means that cont-sys.tex is no longer loaded in
 mkiv which is okay as normally nothing in there concerns mkiv. If you
 use that file for setting up for instance another default paperformat,
 you'd better create a cont-sys.mkiv file. (Maybe that file should go
 and we should use the configuration file instead.)

 - The multilingual interface and messages are now loaded at the \LUA\
 end. If you observe problems, please let me know.

 - If you are adventurous you can add the following to cont-new.mkiv

\enablemode[*nofonts]

 This will postpone font loading and will be default soon. This saves
 runtime when you use another font than latin modern. When no font is
 loaded before the first \starttext, modern will kick in. A side effect
 is that any text typeset before \starttext will not show up in the
 output. If you observe that, you need to setup a bodyfont explicitly
 beforehand. In practice there should be no problems. The delayed
 loading is somewhat tricky but has been tested for a while.

 - There have been some fixes to linebreaks in verbatim. Hopefully I
 didn't mess things up too much.

 - An upcoming version will also have \nonknuthmode as default. You can
 test this by putting this macro in cont-new.mkiv.

 Hans

Re: [NTG-context] Custom XML Pretty Printer

[Renaud AUBIN]

Hi Aditya and happy ConTeXters,

I've worked at the beginning to include those spaces in the different
syntax highlighting groups but failed. Considering the definition of
Comment in the grammar provided by t-pretty-ra-xml.lua:

−−−
we have the following lua code:
Comment =
makepattern(handler,comment, Comment_open) *
(
V(line) +
V(whitespace) +
makepattern(handler, comment, Comment_content)
)^0 *
makepattern(handler,comment, Comment_close),

Here I use the fallback mechanism to the default grammar, defined in
v-default.lua, with V(line) and V(whitespace).

−−−
To circumvent the problem described by Aditya, I assumed that I could do
(since I cannot remember my first experiments, ante git versioning):

local line =  patterns.newline * (patterns.emptyline)^0 * patterns.beginline
local whitespace = (patterns.space + line)^1
[…]
Comment =
makepattern(handler,comment, Comment_open) *
(
makepattern(handler, comment, line + whitespace +
Comment_content)
)^0 *
makepattern(handler,comment, Comment_close),

The newlines are no more detected… I've tried some other code but
everything failed…

I don't know if this is related but, as you have probably noticed, I
don't manage multiple empty lines too.

I'm out of ideas, good as bad…


Hans, or another Guru, to the rescue? More than a solution for Aditya,
it would be nice to give me some line/space stuffs' tricks since the
resulting code could be cleaner and leaner too…

Cheers,

Renaud

My experience is that it is best to use minimals, so maybe it can help
if you give it a try… That's trivial with ./first-setup.sh (I usually
suffix the dir name and use a plain ConTeXt symbolic link… just in case
to recover a previous version if the new one… um… doesn't work).

Best regards,

Renaud

 Something is wrong with your installation. Mkiv should have found
 a texmfcnf.lua at this spot. What distribution are you running?

 the system is debian testing.
 i have the distribution packages installed for texlive and so on.

 I got context from here:
 http://packages.debian.org/experimental/all/context/download

Re: [NTG-context] ConTeXt does not execute MetaPost (in debian experimental)

[Renaud AUBIN]

Hi Aditya,

Hum… OK, my english is not so good but Tested on the following
**ConTeXt minimals** version on an up-to-date debian seems clear to me.
And, you are right: /usr/local is one of the place to install stuff
**not** installed by the debian package manager. ;)

Now, I have installed the pointed package for testing and I confirm the
result:

 Are you using the debian package that Jonas linked to?
 /usr/local/ConTeXt_version_2010.11.26 seems to be a strange place for

Re: [NTG-context] ConTeXt does not execute MetaPost (in debian experimental)

I assume from minimals install script that you need to generate the
format with mtxrun --generate --tree=xxx --some --options but failed
at this point…
Maybe Mojca or Arthur (as authors of bin/mtx-update.lua) could complete?

Anyway, the post-install script packaged with that .deb doesn't seem to
do the job for you…

Re: [NTG-context] colors for pretty-printing

I need to not redefine.

Quoting Hans: maybe you should protect the color names as for instance
redefining darkred might not be the intention

In fact, I just need to find unique names for my colors to not overload
the existing ones…

 I still don't understand. Where do you need to redefine darkred?

Re: [NTG-context] colors for pretty-printing

Ok but then why did you define a specific color palet?

local function color_init()
color = 0
local def_colors = -- \setupcolor[ema] introduces new line...
\\definecolor [darkred]   [r=.545098] ..
\\definecolor [orchid][r=.854902,g=.439216,b=.839216] ..
\\definecolor [rosybrown] [r=.737255,g=.560784,b=.560784] ..
\\definecolor [forestgreen]   [r=.13,g=.545098,b=.13] ..
…

Renaud
 With \setupcolor[ema] or \setupcolor[ema, x11, xwi] there are already a lot of
 predefined colors, so I don't think that you need new color definitions in the
 module

Re: [NTG-context] colors for pretty-printing

[Renaud AUBIN]

 You don't need that. There is already a standard interface for color and style
 configuration. Example:

 \setupstartstop[CSnippetComment][color=blue]

 So you can simplify t-pretty-c.mkiv:

 \unprotect

 \setupcolor[ema]

 \definestartstop
 [CSnippetName]
 [\c!color=darkgoldenrod,
  \c!style=]

 and so on...
   
OK, but anyway, I have to protect the color names (to prevent darkred
redefinition for example ;) )… So, I have made the choice to use
Csomething and it is not annoying as soon as the source color names are
kept…

Cheers

Color abstraction.

u-pretty-c renamed to t-pretty-c as suggested by Hans. Colors are now

Concerning the color abstraction patch, one needs just to overload
Ccomment, Cpreproc, Cstring, Ctype, Ckeyword, Cname and Cfuncnbound to
use custom color scheme.

 The only thing in common with emacs, is the default color-scheme. You can get
 any variant just by changing the color setup.

Re: [NTG-context] pret-c.lua - v-c.lua

Hi Peter,
 Yes, I've tested with my standard test.tex and it's really good, even more
 coloring than my pret-c.lua !
I have added variable name coloring as in GNU/Emacs + { } block
delimiters coloring (that's straightforward when starting from Hans's
v-lua.lua).
 I let you add your copy(left) stuff
 Why me?
That code is not directly from your pret-c but You could be credited
since your work is my entry point…
 and I will make a public git repo on gitorious if you agree.
 Good idea (how could I disagree???).
Ok, then it will be done later this evening.
 Many thanks for your efforts!
Your welcome, that's only a small contribution considering all the
questions I have posted to that list until now.

Cheers,

Renaud

Re: [NTG-context] \todo

[Renaud AUBIN]

Hi Jörg,

It would be nice to have a native ConTeXt support… Ok ⇒ on my someday.org ;)
I'm interested by your (even-still-very-primitive) ruby script…

Renaud, implementing GTD with org-mode for 3 months

 Yes. I have been using org-mode for about 2 years, and I'm now doing
 everything except e-mail there. I have files like lectures.org that
 would contain everything pertaining to lectures: Dates and TODOs that
 I can export to the agenda, links to papers, tables with data, code
 blocks acting on those data (babel), and lecture notes and handouts
 that I export to pdf. The way I'm doing that is: export to a (latex)
 .tex file (provided by org-mode) and then converting to a ConTEXt .tex
 file with a (still very primitive) ruby script I wrote for the purpose.

 One of the advantages is that, in order to communicate with my
 colleagues, I can export to html and then (as long as the document is
 not too complicated) import it in OpenOffice.

 Cheers, Jörg

2 − This separator must be followed by text, and the inbetween vertical
space must be configurable (i.e. .5lineheight or a full lineheight
doesn't satisfy me)

My first idea has been to combine a vertically centered line with inleft
or inmargin but that introduces an annoying afterspace…
Another idea could be to combine some \hairlines or full textwidth
fillinline but then don't know how to vertically align my inmargin text…

[NTG-context] Toward the use of inleft for custom secti on's command… or not…

[Renaud AUBIN]

Hello there,

Thanks to a hdd crash, I need to rewrite an old document of mine from
scratch (after setting up a software RAID on my machine).
Unfortunately, I let my ConTeXt faculties to rust…

I must deal with several problems (but I will apply the good old divide
and conquer rule).

So, here is a collection of unforgivable workarounds to produce what I
want to:

−
\enableregime[utf8]

\setuppapersize[A4][A4]

\setupbodyfont[10pt]


\setuplayout[reset]
\setuplayout[
  location=singlesided,
  leftedge=0mm,
  leftmargin=45mm,
  rightedge=0mm,
  rightmargin=0mm,
  backspace=60mm,
  topspace=10mm,
  bottomspace=10mm,
  header=0mm,
  headerdistance=0mm,
  footer=0mm,
  footerdistance=0mm,
  margindistance=0mm,
  height=fit,
  width=fit,
  grid=yes]

\setuppagenumbering[state=stop]

\setupinmargin[style=normal,align=outer]

\define[1]\SectionCommand {
\blank % just because I always need some vertical space just before my
Section
\inleft{\bfa #1}
{\line{\leaders\hbox{\vrule width 1pt height .5\strutht depth
  -\dimexpr.5\strutht-\linewidth\relax} \hfil}}
\blank[-1*big] % Are you kidding me with that negative blank???
}

\define[4]\TopicCommand {
\inleft{{\em #1}}{\bfa #2 \hfill \tfx #3}
% \crlf % OK, give me a newline! But, the problem is that there is a big
%   % after space from inleft!
\blank[-1*big] % REALLY DUMMY WORKAROUND!!!
{\em #4}
}

\starttext

\SectionCommand{A Section}
\TopicCommand{The date}{Knuth's topic}{some text}{The detailled topic
  (more than one line)}

\input knuth

\blank % Are you kidding me???
\TopicCommand{Another date}{Zapf}{some text}{The detailled topic
  (more than one line)}

\input zapf

\SectionCommand{Section}

\TopicCommand{A date}{Tufte}{}{Some details}

\input tufte

\stoptext
−

OK, I need that… but a clean version…

Best Regards,

Renaud

Re: [NTG-context] XML pretty printer?

[Renaud AUBIN]

Hi ConTeXters,

I have a first operational version of my lpeg-based xml pretty
printer: http://www.nibua-r.org/gitsnap/pret-xml/
operational means:

1 − That pretty printer will type only partially valid xml file
test/other will be considered valid
test att=testsome invalid text / is not considered valid
…

2 − A real namespace management is missing, thus foons declarations will
be prettyfied as standard attribute and foo: will be processed just as
plain tag name.

3 − Endlines within CharData are not yet supported.

As I'm a lua and lpeg beginner, the code provided is not subtle nor
optimized…

That pretty printer is slightly different of standard pretty printer
since a lpeg grammar is applied on a full buffer, i.e. not on a
line-pre-line based approach. The main drawback, not verified, is that
if you have a huge xml file to process, it will just explode the stack…
An analogy: in memory tree xml vs. parser…

It's far from perfect but you are welcome to use, review and give feedbacks…

(… and OK, it's not packaged as a third party module yet…)

Re: [NTG-context] XSL-FO to PDF?

[Renaud AUBIN]

XSLT is fully adapted to XML/XML(fo or other target schema) since it was
the design basis…

My experience is:
− good xslt is (relatively) easy to design as soon as you master the
underlying data model
− xsltproc is REALLY REALLY fast for xslt 1 processing
− if you want something smarter, go for java with saxon/xerces, which is
performant too…

I'm the devil's advocate but what's your need to use ConTeXt. I have not
read all your threads but if you just need:
− to produce pdfs from xml data
− without advanced typesettings
you could use xslt to produce DocBook 5 xml file, include them using
xi:include href=./data/stuff.xml/, configure your layout with an
intermediate xslt + Fo xml config…

Once more, it depends on your original ecosystem and constraints…

If you provide a use case, I should provide a sample if you don't need
it within a couple of hours (but a couple of days)…

Best regards,

Renaud

 Actually, I could write some XSLT to convert the XSL-FO into TeX or
 ConTeXt. But I was thinking it might be beneficial to use ConTeXt to
 process the XML (XSL-FO) directly ... get it all under one roof, so to
 speak.

   
 faster too
 

 Interesting point.  I initially assumed it would be faster to do all my XML
 processing in ConTeXt, but it occurred to me that perhaps using XSLT to or
 even home-grown XML processing, I could generate a stream of TeX that could
 be processed while I'm still producing it.  So one process might be looking
 at successive data records and generating TeX for the various pages, and
 another process could be simultaneously running TeX to typeset those pages.


 Plausible?

 Thank you.

Some precision. I don't think you could consider any pret-xml.lua as an

Sorry, but that's not clear to me… You are certainly aware of the fact
that there is a plenty of SAX / XmlPulParser / CodeSynthesis Tree or
parser samples around on the www.

My two cents: depending of the complexity of the underlying data model
tranported by your xml medium, you should consider another tool
(xsltproc, saxon, xsdcxx, …) and integrate it in your production chain.

Could you describe in detail what your need is (in or off-list)?

[NTG-context] Dummy buff-ver.mkiv question

[Renaud AUBIN]

Hi folks,

From
http://wiki.contextgarden.net/Verbatim_text#Defining_your_own_set_of_colors
and considering the following code snippet from buff-ver.mkiv

\definepalet
  [colorpretty]
  [  prettyone=colorprettyone,
 prettytwo=colorprettytwo,
   prettythree=colorprettythree,
prettyfour=colorprettyfour]

I conclude that we are limited to a four colors palet for our custom
pretty printer… Right or wrong?

Ok, from that basis, one solution could be to directly define custom
colors within pret-xxx.lua… but how?

Any ideas?

Re: [NTG-context] XML pretty printer?

[Renaud AUBIN]

The local pret-xml.lua is used when running context on pret-xml_test
from the basedir.
To get the original pret-xml.lua and check the differences, just rename
pret-xml.lua to pret-xml.new and re-run context…
You should see some differences between the good ol'pret-xml and the
draft of mine… I don't remember if that's due to my configuration or if
that's the default behavior…

The color used is indeed the default one… See my last post

 Pardon my ignorance, but where in your test file is your pretty

 Ah OK, now I see. But I don't think this is a good idea - creating
 your own file with the same name as files in the core. You should at
 least add a t- to the name so people see it's a third party addition.

Re: [NTG-context] POV-Ray

[Renaud AUBIN]

Hi, I indeed agree with Taco… but it depends on your input format, your
purpose, etc.

For me, the issue can't be resumed to a power comparison between povray
and metapost because these tools serve differents purposes!

If you want to obtain 3D realistic rendering (with raytracing), you
definitely have to use povray, YafaRay and co. and embed the resulting
image(s), or movies as usual (I myself never try to embed movies and
consequently can't state if that's possible).

Else, if you already have an existing 3D model (using 3ds, blend, lwo, …
format), wanted to *embed* (not just as an image) it within your final
document/pdf with *potential interactivity* and if realistic rendering
is not your point you should consider using u3d or prc format and read
and try to use it. Search the ML for further details. The main point
here is the 3D model conversion to u3d or prc…

If you start from scratch and really want to *embed* your 3D model,
consider using asymptote to produce a prc file and proceed as in the
previous point (see the ML for details). I have never done that.

The real issue is: what's your need ?

For example, on the one hand I have used u3d embedding for my PhD slides
because I wanted to be able to show some details of my 3D model but
doesn't want to open a heavy CAD application… On the other hand, I have
used povray renderings on the very same 3D model in my PhD thesis. I
have used metapost a lot for the same document, but only for 2D
diagrams… 


Best regards,

Renaud

Joshua Thanks in advance.

Hi Joshua,

There we use the following chain:
- Edit UML diagrams with bouml (a really really great tool to design and
  for reverse engineering… )
- Export to SVG (take care of the font with qt-config if you want some
  consistency within your final pdf)
- SVG to PDF conversion with inkscape (command line + fonts embedding
  option if needed)
- just use the PDF as another external figure…

I'll check tomorrow if I have succeeded to optimize the fonts embedding
(this point has annoyed me a lot)…

From my POV, MetaUML is not adapted to a real production environment
(except at pure design stage)…

Worth give à try to bouml - pdf
Your UML diagrams should look great with a few bouml/fonts/qt-config
configuration.

ctxtools --purgeall doesn't exist but ctxtools --purgefiles works well.
Besides, context --purge(all) works but from your question I realize
that context --purge certainly wraps a ctxtools' call.

Re: [NTG-context] from latex pstricks to context

PS: i dont like metapost

Salut,

From my humble experience, I have faced the very same dilemna (back in 
2003) and... I have switched to metapost...
Did you try to use metapost + metaobj ? See sections 10.3 and 7.7 of 
http://tex.loria.fr/prod-graph/momanual.pdf.


What's the complexity of your graphics? Did you use special pst-circ 
stuffs or others?


If you choose to get stuck with pstricks because you don't like 
metapost, you should use \externalfigure.

Re: [NTG-context] Mark IV Syntax highlighting support

[Renaud Aubin]

Hi folks !

I have just finished a first draft of pret-xml.lua:
- I need to improve its coverage (html);
- DTD declaration is not yet managed;
- I do nothing about re-indentation since I prefer to format my xml 
sample by myself (by hand or using xmllint);
- That's my first try to lua/luatex (after several months of Java...) so 
my definitions (esp. for functions) is not clean at all (you have been 
warned);


I have done it the trial/error way without much design reflexion just 
for fun (I'm on vacation)... I'm not sure it will be reusable...


Take all your test files and please report issues (or give me advices)! ;)

Thank you Matthijs!

Where to start with this topic (current state in Mark IV, roadmap, ...) ?

I've been struggling with this a bit as well lately and found there was next
to no documentation. I've managed to create my own pretty printer, and tried
to update the docs a bit. See [1] and [2] on the wiki for more info. There are
still some details I don't get (why is there a line() hook, what is all this
nesting stuff, etc.), so feel free to find out more and improve these pages!

Re: [NTG-context] 3D PDF support (AKA asymptote support)

[Renaud Aubin]

Michail Vidiassov a écrit :
While MeshLab may be of great use if you have to convert old data or 
process output from some existing tool, in cases when you make your 
model from scratch by hand or create 3D model file in your own program 
Asymptote may be a better choice since it supports newer PRC 3D 
format, that is much richer in features and has better prospects when 
it comes to support and development by Adobe. On the minus side 
Asymptote is under active development and some of its advantages are 
not there yet - but so is ConTeXt.
Ouch, another new 3D format! This will never end. I bet no valuable Open 
Source modeler (i.e. blender) support this one. The fact that asy 
supports PRC is good but I have no illusion about the conclusion of the 
3d formats' war (just an endless pain for developpers)...

Re: [NTG-context] TikZ, MKIV and font switching

[Renaud Aubin]

Mojca Miklavec a écrit :

I don't know about helvetica since it's broken at the moment, but with
   \usetypescript[palatino]
   \setupbodyfont[palatino,12pt]
the labels inside the mindmap are already typeset in gyre palatino
here. What version of ConTeXt/LuaTeX/TikZ do you use?

In MKII the colors are broken though. Hans? Has anything changed in
color handling mechanism recently? I don't know whether I need to
bribe you or Till Tantau to fix the issue. (But I need to admit that I
didn't update ConTeXt in the last few days.)
With MKIV (ConTeXt  ver: 2009.04.06 21:42 MKIV  fmt: 2009.4.8  int: 
english/english) and latest t-tikz the result is good with palatino.


I have processed the test file with

\startMPenvironment[global]
 \usetypescript[postscript]
 \setupbodyfont[postscript,ss,12pt]
\stopMPenvironment

and the mindmap labels are in Termes... Any idea about a workaround to 
obtain my labels in Heros ?

[NTG-context] TikZ, MKIV and font switching

[Renaud Aubin]

Hi folks,

I would use TikZ/mindmap to make some figures for a paper. Since I
have to install TikZ, I have updated my minimals yesterday and began
to really use MKIV. My problem is that when I process

\enableregime[utf8]
\useencoding[ffr]
\mainlanguage[fr]

\usetypescript[helvetica][texnansi]
\setupbodyfont[helvetica,12pt]

\setupcolors[state=start]

\usemodule[tikz]
\usetikzlibrary[mindmap]

\starttext
\input knuth

\starttikzpicture[font=\nofont,mindmap,text=white,
 root concept/.style={concept color=blue},
 level 1 concept/.append style=
 {every child/.style={concept color=blue!50}}]
 \node [concept] {Root Concept}
 child[grow=30] {node[concept] {child}}
 child[grow=0 ] {node[concept] {child}};
\stoptikzpicture

\input tufte
\stoptext

the font switching is OK for the \input *** things but not for the
embedded text. That's probably due to my lack of knowledge of TikZ but
I have just found nothing usefull (nothing evident even in the pgf
manual) about font switching within TikZ pictures with ConTeXt...

(This is LuaTeX, Version snapshot-0.37.0-2009040617 (Web2C 7.5.7))

Best regards,

Renaud

[NTG-context] Color rendering transparency with metapost

[Renaud Aubin]

Hi,

I have some trouble using a gradient background (solid) with a 
transparent element :

  \startMPinclusions
def test_shade (expr a, b) =
pickup pencircle scaled 1mm ;
color ca ; ca := \MPcolor{a} ;
color cb ; cb := \MPcolor{b} ;
color cc ; cc := \MPcolor{c} ;
sh := define_linear_shade(origin 
shifted(0cm,.5*\overlayheight),origin,ca,cb) ;
fill fullsquare xscaled \overlaywidth yscaled \overlayheight 
withshade sh;
draw origin withcolor cc;
draw origin shifted(0cm,-.25*\overlayheight) withcolor cc;
enddef ;
  \stopMPinclusions

  \setupcolors[state=start]
  \definecolor[a][r=.57254902,g=.784313725,b=.917647059]
  \definecolor[b][white]
  \definecolor[c][darkred]
  \starttext
 
  \defineoverlay[bgoverlay][\uniqueMPgraphic{bg_top_shade}]
  \setupbackgrounds[page][background=bgoverlay]
  \startuniqueMPgraphic{bg_top_shade}
test_shade(origin, origin shifted(0cm,1cm));
draw fullcircle scaled 10cm shifted (0cm,0.25*\overlayheight) 
withcolor transparent(1,0.5,white) withpen pencircle scaled 2cm;

 If you comment out the previous line the color rendering is 
definitelly different...

  \stopuniqueMPgraphic
 
  \input knuth
 
\stoptext

I have searched the ML without success, any idea ?

Regards,


Renaud

Re: [NTG-context] Color rendering transparency with metapost

[Renaud Aubin]

Thank Luigi for your response,  the problem is that the background color 
rendering isn't the same if you comment out or not the following line : 
draw fullcircle scaled 10cm shifted (0cm,0.25*\overlayheight) withcolor 
transparent(1,0.5,white) withpen pencircle scaled 2cm;

After some experiments, the problem is solved ( hence not understood 
???) using rgb=no in setupcolors...

It's maybe a viewer-centric problem : I use acroread 8.1.2 under linux.

 Mark IV's framework for syntax highlighting is definately easier to
 use if you are somewhat familiar with 'normal' scripting languages
 (as opposed to TeX). But 'end of october' is pretty close, so I would
 suggest using t-vim, maybe with some postprocessing.

This one was only relevant using texfont...

 I had to had the line  \usetypescriptfile[type-buy]  to the test
Ok (as you may already know), you can modify (your TeX

 A good test is:

Re: [NTG-context] luatex

[Renaud Aubin]

Hi,

For my particular case:
1. embed u3d models within a pdf without piping to an external script to 
compute the view (see http://www.nibua-r.org/ConTeXt/devel/new3dartwork/),
2. the ability to use lua script leads to potential interaction with 
MySQL (it could be great for me but I need to verify it's possible).

...

Cheers

[NTG-context] Multiline footer

[Renaud Aubin]

Hi folks,

I need to define a multiline footer for a document of mine. I have 
searched the garden without results.


Considering \input knuth as a disclaimer, here is a non working sample 
to improve:

\setupfootertexts[]
\setupfootertexts[\setups{text a}]

\startsetups[text a]
\input knuth
\stopsetups

TIA

Hi Arthur,

I wasn't able to test my answer because I use myself a different file structure
for the beginners manual and never encountered this problem.

The better solution rather than making a TEXINPUTS entry is to put the
setup module
in the third party directory in your local TeX tree.


It works at least on my debian box with tetex...

I've always the same old problem described in Re: [NTG-context] enco-ffr

TIA

 There is a new current context that Hans uploaded just moments ago,

Hi Hans,
 i'm no sure what you mean here

 Hans
As a sample is better than words, the following code contains the 
problems induced by the use of \useencoding[ffr]. The first part is only 
here to ensure the correct horizontal spacing. The second part raises 
the problem related to the use of : within ref. The last part is 
dedicated to the well identified MP-related problem.

Hi Hans,

I just mean that the problem was not correctly described in the

I've not cleaned up with texutil --purgeallfiles before to process 
prd_phd with texexec.

Could you describe how \installactivecharacter and discretionaries 
work ? (this way, next time I'll maybe be able to debug myself)

[NTG-context] Custom itemization broken by the new release

Hi all,

The following code

  % frenchitemize

  \setupitemgroup[testitemize]

\starttext

\stopfrenchitemize
\input knuth

\page
\input knuth
\starttestitemize

demonstrates (?) the fact that [indentdash,packed,joinedup,intext] 
options don't lead to the expected result, i.e. the intext option break 
the packed one in the definition of testitemize.

[NTG-context] enco-ffr ?

Hi all,

I've installed the latest ConTeXt (+ pdfTeX 
3.141592-1.40.0-beta-20061017-2.2 + MetaPost 0.99, the beta one) from 
scratch on a machine of mine... In order to test this brand new 
installation, I've processed my phd and experienced some problems:
1- the new enco-ffr contains
\installactivecharacter :
\installactivecharacter ;
\installactivecharacter ?
\installactivecharacter !
These \installactivecharacter yield to

! Extra tokens will be flushed.

directdiscretionary
l.54 } enddef \directdiscretionary

Ok, the problem is solved if I comment out these lines and the 
horizontal spacing seems to be correct...

2- I have now the following error:

Re: [NTG-context] How to get a PhD with ConTeXt (+ hard work ;) )

Hi Mojca,

Mojca Miklavec a écrit :

textext? Did it work? On my computer it hangs after approximately 13
plots. The suggested option is to use sometxt now.
  

textext works for me, all my plots use this option.

Even better (faster) if you have a compiled version of plots and only
include PDF ;)
  

Ok, but what about font embedding ? I precisely like to proceed the plot
as mp code because of the embedding of fonts...
I explain: when I began ConTeXt, I included plots as pdf from
LaTeX+PStricks and I observed an annoying fact, i.e. the fonts are
embedded twice !
For this reason, when I heard of a context (via mp) term, I tried it...
with success...

[Renaud AUBIN]

Mojca Miklavec a crit:

  
Nice work! I can't read French, but the figures are very nice and
content is probably interesting as well ;)
  

Thanks!

  I didn't know that people were indeed using the module already (I
started using it more regularly only recently).
  

dunno (but hope so because of the result...)

  Now one question: how exactly did you create/include the plots? With
"which version of the module"? I don't mind if some of my plots break
if I slightly change the interface before officially releasing it, but
I don't want other people to have problems with that.

You're right. I've used the latest darcs' release (up to the "points
added, some options, etc..." patch). For the inclusion, it's better to
have an example in mind:

 file curves.gp
set terminal context input textext linewidth .3 size 1.2

set output "curves.tex"

set xlabel "$x$ (m)"
set ylabel "$z$ (m)"

set notitle
plot sin(x) with lines lw 2 notitle

set xlabel "$t$ (s)"
set ylabel "a label"

set notitle
plot cos(x)

 file gpsample.tex:
\usemodule[t-gnuplot]

\setupcolors[state=start]

\starttext
\processGNUPLOTfile[mybeautifulcurves][curves]

\placefigure[here]{none}{
 \startcombination[1*2]
 {\useMPgraphic{gpg:mybeautifulcurves:1}}{$\sin$}
 {\useMPgraphic{gpg:mybeautifulcurves:2}}{$\cos$}
 \stopcombination
}

\stoptext

The output is processed using:
gnuplot curves.gp
texexec gpsample

With this method, the gnuplot call delivers a curves.tex file one could
keep as long as the plot doesn't change... Can be usefull when you have
a big document! ;)

I'll write a paper entitled "How to get a PhD with... ConTeXt" asap (I
have the summary and the ideas but time is missing these days, as
always and, moreover because of my new job...). It'll mainly be a paper
about integration (m-bib, gnuplot, mp, etc...)

Best regards


Renaud

PS: what will you do to manage your gnuplot module for ConTeXt ?
Include it into official gnuplot ? It's maybe the time to keep it "well
managed", with supelec foundry for example... What your opinion ?

Hi M.J.,

M.J. Kallen a écrit :

Maybe Renaud can tell us a little more about the details of the typesetting? 
What font did you use and what program did you use to make the plots (I 
particularly like the fact that the font in the plots is the same as in the 
text!), it reminds me a little of R plots, but I may be wrong... And the 
flowcharts are made with the chart module if I'm not mistaken?
  

I use lucida fonts (http://www.tug.org/store/lucida/order.html). The
plots are made with t-gnuplot (http://wiki.contextgarden.net/Gnuplot)
thanks to Mojca's work. flowcharts are made with the chart module,
you're right.
