[NTG-context] Re: [ using horizontal table lines ]

I'm probably using the \starttable incorrectly:

with this code I only get only *one* horizontal line in the header

[...]

with this code I get two horizontal lines, but the second is too short.

[...]

with this code I get two horizontal lines, with correct length, but 
above the wrong columns


[...]


diff:
\NC\DC\DC\DC\DL[4]\DL[4]\AR
\NC\DC\DC\DC\DL[4]\DL[3]\AR
\NC\DC\DC\DL[4]\DL[4]\AR

There is (probably) a correct way to solve this.


My suggestion is to switch to either natural table or extreme tables but 
it seems to me there is a problem with the division lines which always 
leave an empty column afterwards.


The following example should add horizontal lines above the first and 
third column but this setting results in an error. When I omit the last 
\DC the error disappears but as can be seen in the output the second 
line appears above the fourth column.

Yes, the \'s need to be escaped in Lua. And it's made me realise that the 
process of identifying the four lines of the question is separate from the 
typesetting of the question later. The amended version below uses your 
\tareaABC macro to format the question so you can more easily change the layout 
without having to understand ConTeXT Lua Documents in detail.

\startluacode
  userdata = userdata or {}
  
  function userdata.formatTestQuestions()
local the_buffer = buffers.getlines("TestQuestions")
local tracker = 0
local the_question = {}

-- Go through the buffer of questions one line at a time
for i = 1,#the_buffer do

  -- Skip blank lines but 'collect' non-blank lines until we have four
  -- (which is assumed to be a whole question)
  if  string.strip(the_buffer[i]) == "" then
tracker = 0
the_question = {}
  else
tracker = tracker + 1
the_question[tracker] = the_buffer[i]
  end
  
  -- If tracker has got to 4 then we've read four lines
  if tracker == 4 then
context.tareaAbc(
  the_question[1],
  the_question[2], 
  the_question[3],
  the_question[4])
  
-- Reset for the next question (in case no blank line)
tracker = 0
the_question = {}
  end
  
end
  end
\stopluacode

\def\startTestQuestions
  {\dostartbuffer[TestQuestions][startTestQuestions][stopTestQuestions]}
\def\stopTestQuestions
  {\ctxlua{userdata.formatTestQuestions()}}

Thanks a lot Bruce, that did the trick! definitely I will have to learn a bit 
lua in summer.
I just got an error on \qquad and found searching in internet that it was 
because escape character conflicts between tex and lua. For the time i removed 
it and since I will create itemizes I hope I dont get that error if I use \item 
instead of \qquad.
Thanks again, I spent hours of trial and error, error, error... on this matter.

A variation on Hans original suggestion is to use a buffer instead of a 
separate text file, combined with Lua.

\startluacode
  userdata = userdata or {}
  
  function userdata.formatTestQuestions()
local the_buffer = buffers.getlines("TestQuestions")
local tracker = 0
local the_question = {}
local letters = {"-", "a", "b", "c"}

-- Go through the buffer of questions one line at a time
for i = 1,#the_buffer do

  -- Skip blank lines but 'collect' non-blank lines until we have four
  -- (which is assumed to be a whole question)
  if  string.strip(the_buffer[i]) == "" then
tracker = 0
the_question = {}
  else
tracker = tracker + 1
the_question[tracker] = the_buffer[i]
  end
  
  -- If tracker has got to 4 then we've read four lines
  if tracker == 4 then
context.startlines()
context("{\\bf Beispiel:} %s", the_question[1])
context(true)
for answer = 2,4 do
  context("\\qquad %s) %s", letters[answer], the_question[answer])
  context(true)
end
context.stoplines()
  
-- Reset for the next question (in case no blank line)
tracker = 0
the_question = {}
  end
  
end
  end
\stopluacode

\def\startTestQuestions
  {\dostartbuffer[TestQuestions][startTestQuestions][stopTestQuestions]}
\def\stopTestQuestions
  {\ctxlua{userdata.formatTestQuestions()}}

\starttext
Here are some questions:

no, I just want to split at the end of each sentence to get the four arguments: 
now I pass this four lines to my macro \tareaAbc (with the dirty trick of ñ)

In den Büchereien gibt es auch …ñ 
… Kuchen.ñ   
… Theater.ñ

and I wish your context.foo(lines[i]) iteration would become a single 
context.tareaAbc(the four arguments somehow separated so that I can manage each 
line with the corresponding context formatting)

As you see my definition is: \def\tareaAbc #1ñ#2ñ#3ñ#4ñ{...context formating 
for each #)}; Its the clue to pass each sentence as an independent argument 
that I don't get to work.

I need to detect \par or whatever sign marks the newline character as an

For the example, I use this macro definition (which does no work!)

\long\def\prueba

I get: tex error on line 493 in file ./prueba.tex: The file ended when 
scanning an argument.


the macro seems to  read to the end of file not detecting \par; I know 
its the \par that causes the problem; I used ^^M also which I read is a 
sinonym for return but it also does not work.


Help would be appreciated (my computer keyboard would appreciate it too...)

better start thinking something:

TeX primitives ?

Apologies if you are already aware:

There are 21 ConTeXt manuals entitled "low-level TeX" here:

https://wiki.contextgarden.net/Documentation

These might be a good place to begin exploration of interactions between TeX 
primitives and ConTeXt.

As I already wrote you can use \parindent etc. in your document but 
unless you

know what you're doing you should keep it to a minimum to avoid conflicts
with other mechanism which rely on certain settings, e.g. changing the 
\parindent

value can result in unwanted result with paragraph indentation set with
\setupindenting[...].

You mix up two different things here.

1. Plain TeX is a collection of TeX macros like ConTeXt or LaTeX.

2. LuaMetaTeX is a program like pdfTeX or LuaTeX which provides commands 
which are used by above mentioned collections to create macros.


Even though ConTeXt provides some commands which available in plain TeX 
not all of the are supported which means you can't process plain TeX 
documents.


On the other hand commands which are provided by the engine like 
\parindent can be used in a ConTeXt document but higher level mechanism 
like \setupindenting are the better choice.

Found it:

\registerunit [prefix] [µ=micro]

\starttext
  \unit{10 micro meter} \crlf
  \unit{10 µm}
\stoptext

Should this be the default (µ assigned to micro)?

You're right \unit{10 Farad} works.

Makes sense if you think about it. Never crossed my mind that ft not
meaning feet in this instance and also never contemplated the
existence of a “femto tonne”.

That gives some insight, indeed. Thanks.

What about:

\unit{10 um}
\unit{10 µm}

Can I assign µ to mean micro (prefix)?

Hi!

I struggle using the unit Farad (unit of capacitance):


The unit "farad" exists.


\starttext

%% prints 10 10 ft
\unit{10 F}
\unit{20 ft}

\registerunit  [F=Farad]
\setupunittext [Farad=F]

%% prints 10 F 20 F⋅t
\unit{10 F}
\unit{20 ft}

\stoptext

When registering Farad as new unit it messes up feet. This looks
like a bug to me, since “20 ft” does not contain a capital “F” and
units are case-sensitive. How to use Farad correctly without messing
up other units?


The unit for feet is "foot" and "ft" is a combination of a prefix 
(femto) and a unit (tonne).


You can list the individual parts in the log file with the 
"physics.units" tracker.


To get a short unit you have to use the following method (it works 
because farad exists):


    \registerunitshortcut [F=farad]

You need a box to get the author on a separate line.

Thank you so much, Wolfgang!

Why do you need protected here? I’ve realized that \protected\def also 
helps a bit, but, of course, paragraph breaks are ignored there as well…


You probably haven't noticed it yet but unlike the other predefined 
layouts for sections you don't have to write "alternative=command" to 
use the layout which is passed to the command key.


To make this work ConTeXt has to check whether the argument of the 
command key is empty or not but this is problematic when you pass 
commands with arguments.


When you try to example below you can see that the first definition of 
\Mycommand fails because \edef\CheckMycommand tries to expand its 
argument which causes problems because \Mycommand tries to read the 
following argument. To solve this problem you can use the \protected 
modifier when you create \Mycommand.


\starttext

\def\Mycommand#1{#1}% fails
%\protected\def\Mycommand#1{#1}% works

\edef\CheckMycommand{\Mycommand}
\ifempty\CheckMycommand
   \tex{Mycommand} is empty
\else
   \tex{Mycommand} has content
\fi

\stoptext



If just found the following in the lowlevel-macros manual:

«Traditional TEX has three prefixes that can be used with macros: 
\global, \outer and \long. The last two are no-op's in LuaMetaTEX and if 
you want to know what they do (did) you can look it up in the TEXbook.»


So, \long is gone, but why is that? Is there a new mechanism that serves 
the same purpose? Other than using a vbox, I mean…


The purpose of the \long modifier is to specify whether the argument of 
a command can or cannot contain multiple paragraph (either by an empty 
line or with \par). This was needed by TeX in the early days where 
memory was limited but not on the current machines.


For a very long time ConTeXt made each command definition long by 
default (i.e. \def\...{...} behaved the same way as \long\def\...{...}) 
and as a result \long was dropped.


\def\CommandA#1{#1}

\long\def\CommandB#1{#1}

\starttext

\CommandA{xxx}% works

\CommandA{xxx

yyy}% fails because you have a empty line in the argument

\CommandA{xxx\par yyy}%fails because you have \par in the argument

\CommandB{xxx\par yyy}% works because \CommandB is \long

\stoptext

Hi,

is it possible to access a structureuservariable before the heading's title ?
Using the  key does not seem to work.

There are ways but not in a general way because you try to access the values
before they are known to ConTeXt. To provide a proper solution you have
to tell what you're trying to achieve.

I'm just trying to output the author's name above a chapter heading. Do you 
need more information?

You can create a custom header for the chapter page and show the value of the 
author key
which works without problems because the header is added after to the finished 
page
after the value is available.

Another option when the name should appear in the same space as the chapter 
title
is a custom layout for the title.
Yes, I've tried that in the original MWE:

...

Here, I'm getting  just before <3 Third>. So I guess this goes in 
the right direction, but \define doesn't allow for blanks etc. 
\starttexdefinition and \def on the other hand gave me erros.

You need a box to get the author on a separate line.

 Hello Maurí­cio,

 You'll need to convince the author to make a generic package.

 I'm not sure if he's familiar with ConTeXt or not. The changes that
 are needed might be doable in reasonable amount of time (from my first
 impression there are not too many LaTeX-specific commands present),
 but the package won't work out of the box as it stands at the moment.

[NTG-context] re-using ConTeXt typescripts ?

[Steffen Wolfrum]

Hi Adam,

the simplicity of XeTeX's font handling is amazing -- when starting 
from scratch.
But I am wondering how can I continue to use the typescripts (and 
virtual files) that I used to use with ConTeXt?!


texexec --xtx --example.file

ends in an error log containing:

This is METAFONT, Version 2.71828 (Web2C 7.5.4)
kpathsea: Running mktexmf AGaramond-Regular

! I can't find file `AGaramond-Regular'.



As I do not have *any* idea where to start searching for my mistake 
(resp. the place where changes have to be made) I dare to send you a 
complete minimal example (that worked with pure texexec --pdf 
--example.file)


Any feedback might probably help me...

Thank you,

Steffen




I have an example-file, a typescript-file and a map-file.


The example-file goes like this:

[Patrick Gundlach]

Hello Thomas,


[...]

  following the TeXFont manual for ConTeXt, do I have to reinstall 
 them from scratch for ConTeXt starting with the pfb- and afm-files from 
 texmf-local/fonts/source, or can I use the already distributed pfb- and 
 afm-files? 

Yes, as I already answered on the german tex-d-l mailing list. Did you
try my suggestion to add a typescript and just use the fonts?

[NTG-context] Re: Using LateX packages

[Patrick Gundlach]

Hello Holger,

 I want to use a LaTeX Package (clrscode), or at least I want to port
 it to Context.

 http://www.cs.dartmouth.edu/~thc/clrscode/

 Is there some way to use LaTex Packages (I guess not).

No. The low level commands are different in LaTeX and ConTeXt. The
named package does not use a lot of unique LaTeX features, so a port
shouldn't be too difficult. But as I guess from your question, you are
unable to do that, so the question is: who else does the job? And I
guess, nobody rises his hand now.


 Is there documentation about writing ConTeXt modules? (I didn't find any).

There is an API documentation project Taco has written a paper on
some commands, but there is much more to do.

See HH answer about a similar request.
I think this solution could be the start of your package.
Hans had extended the startlines environment with an option
which keep spaces, so that it's easier to write
algorithms without having some \it begining every lines !

Would it make sense to create the metrics and put the online?

- false font names
- missing font names

[NTG-context] Re: using fonts

[Patrick Gundlach]

Hello Wolfgang,

 I think I´mgetting confused with all of the font selection within context.

You are not the first one...

 First: I have a miktex environment on on W2K.

That should be OK for all needs.

 1. to change single fonts:

see http://contextgarden.net/Psnfss

 \definetypeface [palatino] [rm] [serif] [palatino] [default] [encoding=ec]
 \switchtotypeface[palatino][12pt,rm]

I have never used \switchtotypeface.

 2.
 I thought that the default encoding should be texnansi

This depends on your setup. See cont-sys.tex as a place where
defaultencoding is sometimes set.

 3.
 should be there some font-switching macros on the system called
 font-xxx.tex (example font-lbr.tex)? These are missing on my system.
 I think these are needed forthings like:
 \setupbodyfont[lbr, sans, 12pt]

Well the font-xxx.tex files have nothing (not completely true) to do
with the font switching commands.

 4.
 within miktex there are lucida font files from yandy (lbr.tfm
 ). Is that a free version of lucida-font?

No. There is no really free version of lucida. They once came with
staroffice and there was a script that was able to pull them out and
make them accessable for TeX. But I think that the quality is lower
than the original ones (once read a statement from Walter Schmit about
them, don't remember when and where) and math is not included.

 (is that for math? [there is anotherfile called math-lbt.tex in
 \context\base])

No math fonts like lucida for free.


 do I need to get the missing fonts/files and why are they not
 provided with miktex. Perhaps a change of the distribution is to
 prefer? (which one)

No, go ahead with MikTeX. Try out the stuff that is on the wiki and
please report on your success/failure.

 Is there a manual which explains how to change fonts (in a way that a
 normal user who is new to context can understand it)?

yes and no. See the wiki for links.

Re: [NTG-context] Re: using fonts -- installation

[Rob Ermers]

Dear friends,
Let's join the font discussion!
Two years ago I installed under latex an adapted cyrillic font family, 
along with a new encoding (which I named l2t.enc -- a variant of t2a), 
for  koi8 texts, which makes it possible to call special diacritics 
(like \cyrkdot) by means of regular input codes, such as \= and \d. (In 
this way the text can still be processed without the special font and 
its code, but looks less nice.) As anybody can imagine, it was the 
toughest latex thing I ever did, I guess, but it worked and still does.

I am telling you this because after this complicated job I have been 
trying several times to install a simple type 1 font under Context, the 
last time being two days ago, but without any success. (I got the same 
simple font working under latex, though.) I carefully read Adam's 'My 
Way' over and over again, but I cannot get it work in my system. I put 
all the files exactly on the indicated places! (Texfont is very handy, 
but it seems to me, that nevertheless mapping files are not found.) 
Could anybody give me, and some others, a hand?

The font is simply not recognised (log file message: bodyfont: unknown 
variant johanna). Of course, I am still miles away of getting my 
cyrillic font working under context...

Let's not take the font Palatino, because it's already there, but a 
simple font: say, johanna, which consists of two files:

johanna.pfb
johanna.afm.
Which concrete steps do we have to take to make johanna work under 
Context with Miktex? And, perhaps more important, where do I put my map 
files and font files, etc. so that they be recognised?
The next step would be the installation of a ttf font. After that a 
whole font family should not be that difficult anymore.

Thank you very much in advance!
Kind regards,
Robert Ermers

Okay, that sounds odd. How do you define/use the font in ConTeXt?

Let's not take the font Palatino, because it's already there, but a 
simple font: say, johanna, which consists of two files:

johanna.pfb
johanna.afm.

Okay, stick those two files in a temp directory together. What happens with:
 texfont --make --install --co=johanna --ve=something --show

?

Which concrete steps do we have to take to make johanna work under 
Context with Miktex? 

as before, I don't know about MikTeX specifically...

Re: [NTG-context] Re: using fonts -- installation

[Rob Ermers]

Hi Adam,
Thanks for your quick reaction. Before ending this eventful day, I ran 
texexec as you suggested.

The font in question is Hudson (vendor=softmaker = Berry 5), for which I 
 invented the name 5hu (+r for roman). I have the two files 5hur.pdf 
and 5hur.afm.

Texfont generated a number of files and put them in several directories:
- texnansi-softmaker-hudson.map in 
J:\tex\localtexmf\fonts\map\pdftex\context
- texnansi-5hur.tfm in J:\tex\localtexmf\fonts\tfm\softmaker\hudson
- texnansi-5hur.vf in J:\tex\localtexmf\fonts\vf\softmaker\hudson
- 5hur.afm in J:\tex\localtexmf\fonts\afm\softmaker\hudson
- 5hur.pfb in J:\tex\localtexmf\fonts\type1\softmaker\hudson

Texfont also generated the following:
D:\Fonts\hudson\hudson: texnansi-softmaker-hudson.log
D:\Fonts\hudson\hudson: texnansi-softmaker-hudson.tex
D:\Fonts\hudson\hudson: texnansi-softmaker-hudson.tmp
D:\Fonts\hudson\hudson: texnansi-softmaker-hudson.pdf
The pdf file does not show the hudson font - I wonder if it should.
Perhaps I should mention that Texfont was interrupted; atf2tfm gets 
stuck - a conflict with a dll, but if click on OK, nothing serious seems 
to be the matter. The tfm file is generated after all. If I test afm2tfm 
 without texfont, it works normally.

I have a test file, which is called testhuds-con.tex.
Kind regards,
Robert

there is support for cyrillic in context but there are many encodings; i'm sure

that message is an indication that you didn't define it as bodyfont
for instance:
  \definetypeface[johanna][rm][serif][palatino][default]
will provide
  \setupbodyfont[johanna,10pt,rm]
the combination [serif] [palatino] is the main typescript filter, while [rm] is 
what it gets mapped onto; [default] concerns the size
