Hello,
I needed to typeset some poetry and noticed that

Is there a way to make the "tab" render the space "as is"?

[NTG-context] bug in beta: \tab results in text overlap

Hans, I tried the beta of 2013.11.26, and as mentioned in a previous
email, it fixes the \getmarking problem pretty well. However the same
beta has a fatal problem for us: lists using \tab are now broken.
MWE:
\starttext
\tab{AC}Autonomous Community\par
\tab{\it alt.}alternate name for\par
\stoptext
In the TeX Live 2013 version of mkiv, this gives us a nice table with
the headword separated from the definition.
In the beta, the headword and the definition start at the same
horizontal position, and overlap each other.
We use these lists in the context of mixedcolumns, but the overlap
behavior occurs regardless of mixedcolumns.
Any help would be appreciated. If we can't fix or work around this
problem, we may have to abandon the beta and go back to TeX Live 2013,
which means our page header guide words would be incorrect.

Well, it's probably not quite that fatal for our project, because it
looks like the \definedescription mechanism can be used to replace \tab,
and does not suffer from the same problem in the beta.
Nevertheless I thought someone would like to know that \tab has stopped
working, so it can be fixed (or documented as obsolete, in favor of
\definedescription).

There is a workaround:
print(string.format('a\t%s', 'b'))
but I find it weird. Even if the line above gets commented out with
two dashes it still complains.
I understand approximately why this happens, but is that intended?
Should I be using something else than \startluacode in the plethora of
different lua triggering commands?
\start/stopluacode is defined as \startluacode#1\stopluacode
(simplified) and you should take care of TeXs parsing rules.
If you want Lua comments and format command (\n, \t ...) use
a external file for your Lua code.
OK, I will use external files next time. In this quick-and-dirty
approach I just added string.format since it was easier than
restructuring everything.
I thought that \startluacode should be behaving the same way as
verbatim environments where commands inside verbatim have no
influence, but apparently I was wrong.
Thanks,

I thought that \startluacode should be behaving the same way as verbatim environments where commands inside verbatim have no influence, but apparently I was wrong. I also think so. Can be strange, but inside a \startluacode\stopluacode I have no problems to think at -- as comment while I have problems to think to % as comment And put lua code in a separate file not always is a good solution This would be really great, \start/stoplua with % for comments like \ctxlua and \start/stopluacode with -- as comment, the first is used for longer settings in macros and the second for inline functions. @Luigi: You could try to parse the luacode content with Lpeg and with the result back to \directlua. Better to study luat-ini.tex first -- luigi ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : https://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___

Exactly.
In my opinion, this is better than my example, because I don't like to mix
things (and also for namespace document).

no, more like MPcode where one can mix things

[NTG-context] printing tab in lua: print('a\tb') fails
Hello,
Here's a tiny question. The following command complains about
undefined control sequence.
\starttext
\startluacode
print('a\tb')
\stopluacode
hello
\stoptext
There is a workaround:
print(string.format('a\t%s', 'b'))
but I find it weird. Even if the line above gets commented out with
two dashes it still complains.
I understand approximately why this happens, but is that intended?
Should I be using something else than \startluacode in the plethora of
different lua triggering commands?
Thanks,
Mojca

\start/stopluacode is defined as \startluacode#1\stopluacode
(simplified) and you should take care of TeXs parsing rules.
If you want Lua comments and format command (\n, \t ...) use
a external file for your Lua code.

[NTG-context] Possible bug in core-tab?
Hi Hans,
|| does not work with tables, and until now I thought that this was a
limitation of tables. But upon reading core-tab, it appears that you
make a lot of effort to make sure that || works correctly, but it does
not. I think that this is due to a mistake in the definition of
pushouterbarandquote. Currently it is defined as
\gdef\pushouterbarandquote
{\ifForgetTableBarAndQuote
\let|\letterbar
\let\letterdoublequote
\ifnum\catcode`\|=\@@active \let\outertablebar
|\else\let\outertablebar \relax\fi
\ifnum\catcode`\=\@@active
\let\outertablequote\else\let\outertablequote\relax\fi
\fi}
Shouldn't it be the other way round? That is first save the current
meaning of | and , and then redefine it. So,
\bgroup
\catcode`\|=\@@active
\catcode`\=\@@active
\gdef\pushouterbarandquote
{\ifForgetTableBarAndQuote
\ifnum\catcode`\|=\@@active \let\outertablebar
|\else\let\outertablebar \relax\fi
\ifnum\catcode`\=\@@active
\let\outertablequote\else\let\outertablequote\relax\fi
\let|\letterbar
\let\letterdoublequote
\fi}
\egroup
This makes sure that || works correctly. The redefinition of and |
was added last November.

Re: [NTG-context] Feature request: Creating tables from (tab-separated) values
Hi,
Here is a quick hack that converts csv to commalist values.
Perhaps it helpful for someone. Documentation blurb:
This module parses CSV data (somewhat) safely. After
\def\dataline{a,,\j,a,a\j a,t{f}ab}
\convertcsvdata\dataline\to \myascii
\message{\meaning\myascii}
output is:
macro:-{a},{},{\j },{a},{a\j a},{t{f}},{,},{},{ab}
The result is detokenized, like would be with \type{\convertargument}.
Therefore, you will need to run \type{\scantokens} over the list
items if the CVS data was actually \TeX{} code.
Cheers,
Taco

[NTG-context] Feature request: Creating tables from (tab-separated) values
Hello,
This idea described below was partially inspired by gnuplot
contemptations, but mainly because writing tables with both LaTeX
ConTeXt is too complex in most cases.
Natural tables are great since they offer anough flexibility to do
just about anything with tables, but many tables are still simple m
values in n rows and for those it's an annoying task to write those
\NCs, \eTR\bTRs, ... even if it's just a matter of writing a
script to transform the values to a suitable form.
Christopher Creutzig has sent an interesting solution to the mailing
list some time ago (see
http://wiki.contextgarden.net/TABLE#Creating_tables_from_CSV_data_.28Comma_Separated_Values.29)
and since then I've been thinking about a similar, slightly more
powerful solution which could make table-typesetiting easier.
I don't have enough skills to implement it, but here are some
properties listed that such a solution should have. In case anyone
finds this little project doable ... It would solve quite some
headaches.
- [very important] a possibility to define own macros, so that it
would be easy to print any type of tables (natural tables, TaBlEs, ...
or whatever form that could possibly come to someone's mind); for
example \def\MyDef#1#2{\bTR\bTD#1\eTD\bTD#2\eTD\eTR}; the machinery
behind would only have to feed these macros properly according
- [important] possible to separate the data with different characters:
tab, comma, multiple spaces, ampersand (), ...
- [very useful] a possibility to read the data from a block
(\start...\stop...) or from a file; it would be handly to be able to
use the same data file for making a plot and for printing the data
into a table
- [useful] possibility to ignore lines starting with '#' (optional;
usually these are comments)
- [not crucial] if comma (,) is separating the data, a possibility to escape it
- [useful] a possibility to select which rows (columns) to print (for
example rows 1-3,8-last or even, ...)
- [optional, but still useful] replacing decimal points with commas
- [optional] if the table was supposed to have 4 colums and only 2 are
available, ignore/fill with empty arguments (don't panic with
unnecessary errors)
- [with luaTeX in mind] calculating sums of rows columns other
Excel-like calculations references accross tables ;) - well, that
one wasn't meant seriously.
Thanks a lot,
Mojca
