[NTG-context] bug in latest beta?
Hans,
after updating to latest beta I get an error when compiling the sample
bellow with beta from 2014.12.09 13:03:
\setupitaliccorrection[global,always]
\definefontfamily[mainface][serif][TeX Gyre Pagella]
\setupbodyfont[mainface,15pt]

\starttext

\par
\currentdate
\stoptext
Beta from 2014.11.26 21:43 compiles it without problems.
Is this a bug or am I missing something?
Many thanks for your help,
Pablo

It's a bug (I updated some discretionary related code so ther might be a
few more border cases not handled well). I'll make a new beta.

Re: [NTG-context] issue with t-scancsv.lua
On 12/09/2014 12:45 AM, Jaroslav Hajtmar wrote:
Hi Pablo.
I am glad that my library for you to use ...
I noticed that you have in your CSV file header with column names (ie.
head of CSV document). I do not know if you noticed the option put this
information into scancsv.lua library. This is done via the command
\setheader. In this case library does not consider the first line of the
CSV file as a data line.
Hi Jaroslav,
I know that, ubt I removed it in the sample I sent because I edited the
CVS file with gedit and I forgot that the first line was the header (I
was in a hurry).
I actually use \setheader to ignore it, since headers with non-ASCII
characters or spaces are problematic. I’m fine invoking \cA, \cB, \cC...
From the header of CSV file are now macros (from header names)
contain later data from rows of the CSV file (changing in cycle). In
addition, you can also use internal hooks. CSV file can even contain
macros (must be defined before processing the CSV file).
Well, your sample needs further study. Internal hooks are fine (once I
know what they really are and how to use them ;-)), but macros are
totally out of question. CVS files come from Excel users (I don’t even
mention what TeX or ConTeXt might be).
Many thanks for your help,
Pablo
Example of use hooks etc. eg. Here:
\usemodule[scancsv]
\setuppapersize[C6, landscape]
\setuppagenumbering[location=]
% Structure of CSV file - you can use macros in CSV table too
% name;address;postcode;city;linecolor
% ME;STREET;;HERE;\green;
% You;Square;;There;\red;
% we;another Square;111;anyplace;\blue;
% Library is making \name, \address, \postcode, \city and \linecolor macros
% when you using \setheader command.
% Your example:
\unexpanded\def\lineaction{
\edef\lowercasename{\lowercase{\name}}
\edef\uppercaseaddress{\uppercase{\address}}
name: {\linecolor\name}\ -- lowercase name: \lowercasename\crlf
address: \address\ -- upercase address: \uppercaseaddress\crlf
\postcode\ \city\crlf
\page
}
% My example with hooks:
\unexpanded\def\tablelineaction{%
\edef\ehname{\hname}%
\edef\ehaddress{\haddress}%
\edef\ehpostcode{\hpostcode}%
\edef\ehcity{\hcity}%
\ehname \ehaddress \ehpostcode \ehcity %
}
% My simple example with hooks:
\def\simpletablelineaction{%
\bTD{\linecolor\numline}\eTD\hname\haddress\hpostcode\hcity%
}
\setsep{;} % set separator
\setheader % set information about header
\setfiletoscan{mailmergedatatable.csv}
\starttext
% process all file
Here is begin of processing...
\filelineaction
And here is end
\page
And now we can use internal hooks:
\def\bch{\bTD } % begin column hook
\def\ech{\eTD} % end column hook
\def\blinehook{\bTR } % begin line hook
\def\elinehook{\eTR} % end line hook
\def\bfilehook{\bTABLE } % begin CSV file hook
\def\efilehook{\eTABLE} % end CSV file hook
Here is begin of processing...
%process all file too (endless cycle)
\doloopif{1}{==}{1}{\tablelineaction}
And here is end
\page
Printing only specific data:
\doloopif{\name}{eq}{You}{\tablelineaction}
\page
Simpletablelineaction:
\doloopif{1}{==}{1}{\simpletablelineaction}
\page
Another using of hooks:
\def\bch{\bgroup\linecolor\bf } % begin column hook
\def\ech{\egroup,\ } % end column hook
\def\blinehook{Here is new \numline. line of CSV file:\crlf } % begin
line hook
\def\elinehook{\hairline\par} % end line hook
\def\bfilehook{Here is all CSV file:\blank[2*big] } % begin CSV file hook
\def\efilehook{\par Here is end of file processing\par} % end CSV file hook
\doloopif{1}{==}{1}{\tablelineaction}

Fixed, thanks for noticing, it had to do with picking up the right

[NTG-context] Ctx XML
Hello, I'm having problem using LuaXml library with Ctx, both using Lua ver. 5.2. LuaXml works fine with Lua standalone programs/scripts; but something weird occurs when used from within Ctx (e.g. a .xml file can be read successfully from standalone Lua with LuaXml lib; but the same code doesn't give the desired result when used in combination with Ctx; a problem might be version mismatch - I'm still using both Lua 5.1 and 5.2 including 3rd party modules in my scripts - but my latest tests with Ctx LuaXml should have avoid this; or namespace mismatch...?). Anyway, does native Ctx XML API (has it its own namespace, like 'context.xml'?) provide a function to load a .xml file and to return its XML tree as a table, with nodes (as a table with node attributes as table members) in a proper sequence... something like LuaXml's 'xml.load(file.xml)' does? Or how to achieve this in a best way under Ctx: XML file - Lua table/tree? Best regards, Lukas -- Ing.

Yes...

It would be great.
local x = xml.load(file.xml)
local t = xml.totable(x)
where x is an index/hash mix plus _tag, _type and _namespace fields as
well (after all I assume that you need to know that too).
(btw, I bet that you can do what you want with the existing

Probably in the next upload,
... Means - some functionality (for me to test or to play with) might be
available tomorrow morning?

BTW, I prepared a really-simple-XML-test which shows XML - Lua table/tree
conversion, which I'd like to achieve (and which (approx.) provides LuaXml lib).
XML
a aaa=AAA
b bbb=B1/
b bbb=B2
c
/b
/a
Lua representation
{ [0] = a, -- Element name
{ [0] = b, -- Element name
-- No nested members
bbb = B1, -- Atts
},
{ [0] = b, -- Element name
{ c, }, -- Nested member
bbb = B2, -- Atts
},
aaa = AAA, -- Atts
}
Thanks again.
Best regards,
Lukas
