[NTG-context] Re: \m vs $ for math mode

[Mikael Sundqvist]

Hi,

you do not need to change the $ into \m. With \m, you can use some
arguments, like \m[color=red]{x+y}.

[NTG-context] \m vs $ for math mode

[Shiv Shankar Dayal]

Hi all,

I had been using $ for math mode. Then I read the new manual that \m
is better for math mode. Can you please give some examples to see this
in action? BTW, I have started using \m but changing all existing
formulas is very tedious.

Hi!

I'm struggling with the rendering of a particular liquid metal:

This is strange, since both “mercury” and “millimetermercury” are

None of your examples work because millimetermercury and mercury are the

A ha! Many thanks; I've gotten it working, along with this hint:

This, too, was useful - as per the Scratch Variables page in the System Macros 
section of the garden 
(https://wiki.contextgarden.net/System_Macros/Scratch_Variables) I've updated 
my tree-sitter parser (https://github.com/pmazaitis/tree-sitter-context_en) to 
put these in the parse tree; I don't know how useful that is, but it seems to

Oh! Indeed: my working ConTeXt environment is under version control;  
experimental nonsense like this gets safely tucked away in a branch (my 
thinking is that I want to try to change as few new variables as possible - 
still learning!).

I'd recommend completely ignoring the interface i-*.xml files. They
don't do anything particularly useful for a third-party module.

>\c!skipheader=\v!no, % <- Added, following the pattern with strip

This line is your issue. Inside \unprotect...\protect, "!" is treated as
a letter, so you're trying to expand the value of the macro
"\c!skipheader". The problem is that that macro isn't defined anywhere. 

Backing up a little further, the \c!... commands are all string
*C*onstants. If you see a command with a name like \c!blah, it almost
certain expands to exactly the string "blah". Why is this useful? Well,
if you run ConTeXt in another language, then the \c!... commands will
instead contain that string but in the other language. So something like
\c!left would be "left" in English, "gauche" in French, "links" in
German, "vlevo" in Czech, etc. 

You could define \c!skipheader to just be "skipheader", or you could
give it a translated value for 10 or so languages. But the easier
solution is to just use the string "skipheader" directly:

   \setupdatabase
 [\c!separator={,},
  \c!quotechar=,
  \c!commentchar=,
  \c!strip=\v!no,
  skipheader=\v!no, % <-- HERE
  \c!before=,
  \c!after=,
  \c!first=,
  \c!last=,
  \c!left=,
  \c!right=]
   
As a more general suggestion, it is usually a really bad idea to modify the
standard ConTeXt files since any changes will be overwritten on updates.
Probably the best solution is to make a new file called "t-xdatabase.mkiv"
stored in your texmf-local/, start the file with "\usemodule[database]"
then add any changes after that. Or, just copy and paste the original file
into your new file. (Maybe you were doing this already though)
   
Hope this helps,

[NTG-context] [m-database] How to properly add module arguments?

[Paul Mazaitis via ntg-context]

Dear list,

## The Incredibly Short Version

I am trying to extend m-database, and I want to add a flag to control behavior. 
I can get it to work, but I am having trouble understanding how to do it 
properly.

## The Short Version

I have a project where I wish to incorporate many CSV files as Natural Tables.

I want to keep the headers in the CSV files so they're useful in other contexts.

The `m-database` module doesn't have a feature to suppress the header row, from 
what I can see.

(I know `handlecsv` can do this, but I'm having troubles with that; if the 
`m-database` line of inquiry doesn't work out, I'll go back it, but I figure 
I'll focus on this solution for now.)

Looking at the module sources, I can implement the functionality I need in the 
Lua part of the module, but:

I seem to only be able to bodge in additional arguments for the commands in the 
module.

On first try, I got the error: `tex error   > tex error on line 30 in file 
/Users/pmazaitis/Opt/context/tex/texmf-context/tex/context/modules/mkiv/m-databaseplus.mkiv:
 ! Undefined control sequence`

And then: `The control sequence at the end of the top line of your error 
message was never
\def'ed.`

Looking at the docs points me to a solution using  `\def`, but it's not clear 
to me how that's working in the case of the database module (the database 
module seems to be initializing these values someplace else?).

If I \def the settings variable in m-database.mkiv,  I can get it to work, but 
I don't think that's the correct way to go about this.

Question: how do I properly define new module arguments for the database module?

## The Long Version, With MWE

### Files Associated With the MWE

Apologies for all of the file inclusions, but I want to be complete.


Here's the .csv file I'm using for the MWE:

--- begin database-mwe.csv ---

Ref. No.,Part No.,Description,Remarks
,RD14C82E000J,Carbon 000𝝮 ±5% 1/4W,

---  end database-mwe.csv  ---

Some notes on database-mwe.csv:

I'd like to keep the header row in place to make this file useful for other 
tools.

These are lists of electronic parts, so I'd like to include uppercase omega, 
lower case mu, and percent sign characters in the CSV file.


Here's the .tex file I'm using for the MWE:

--- begin database-mwe.tex ---

\usemodule[database]

\setupdatabase[quotechar={"},separator={,}]

\defineseparatedlist
  [PartsTable]
  [separator=comma,left=\bTD,right=\eTD,first=\bTR,last=\eTR,before={
\bTABLE[split=repeat,option=stretch]
  \bTABLEhead
  \bTR
\bTH Ref. No. \eTH \bTH Part No. \eTH \bTH Description \eTH \bTH Remarks 
\eTH
  \eTR
  \eTABLEhead
  \bTABLEbody
   },
   after={
  \eTABLEbody
  \eTABLE
   }]

\starttext

test

\startasciimode
\processdatabasefile[PartsTable][parts_list-test.csv]
\stopasciimode

\stoptext

---  end database-mwe.tex  ---

Some notes on database-mwe.tex:

This actually works pretty well with the distributed m-database module!

Some of these lists are quite long, so I want to use a TABLEhead to replicate 
the headings at the top of a new page. I don't think there's a way to automate 
this with `m-database`, so I'm okay with hard-coding the headers. This does 
mean I get a double header row at the top of the table. I want to suppress the 
header row; I'd like to implement this behavior in the module behind a switch.

(I'm using the `asciimode` environment to dodge problems with unescaped `%` 
characters and Greek letters. I tried adding the startasciimode/stopasciimode 
commands to various keys in the \defineseparatedlist command, but I didn't get 
anywhere with it - I got errors. A problem for another time...)

I think I've got a good handle on how to do this in Lua, but I'm struggling 
with what to add to the switch appropriately.

In attempting to add a switch, I tried the following.

Based off of https://wiki.contextgarden.net/Modules#Modules_writing_guidelines,
I added a stanza to the appropriate interface file:

--- begin stanza added to i-database.xml ---






---  end stanza added to i-database.xml  ---

I modeled that after the stanza for the argument `strip`. I think that's the 
only thing I need to do in the interface file.

Changing the i-database.xml file does not break the build.

However, as soon as I add the skipheader argument to the m-database.mkiv file:

--- begin definition in m-database.mkiv ---

\setupdatabase
  [\c!separator={,},
   \c!quotechar=,
   \c!commentchar=,
   \c!strip=\v!no,
   \c!skipheader=\v!no, % <- Added, following the pattern with strip
   \c!before=,
   \c!after=,
   \c!first=,
   \c!last=,
   \c!left=,
   \c!right=]

---  end definition in m-database.mkiv  ---


...the build fails (with the error from the Short Version section).

If I then add the following \def to m-database.mkiv before the \setu

Thanks for the modified documentation of the graph macros. It has been a
great help. Is it in the lmtx distribution somewhere?

I read about the upcoming luagraph in mag-1104-mkiv.pdf (This Way
11/11/2019) and have also played a bit with LuaMetaFun and Aditya's blog
post. Looking forward to that development, thank you!

Thank you again, but the "0.0" remains unchanged. The only way I've been
able to succeed is with a for loop to label explicitly. See mwe below for
things I've attempted. The last two for lines seems to be what it takes
(with the other Auto lines commented out of course.)

The least-squares fit (to a polynomial) is a deterministic calculation,
not an arbitrary non-linear search. As such, it is very robust.

Certain (useful) functions, a Gaussian peak for example, can be
suitably transformed to a polynomial function, so these are handled as
well, robustly.

Examples are given as comments in mp-grap.mpiv that you can follow.
I can send you off-list an adapted version of the original John Hobby
documentation, with extensions described.

Note that the m-graph module is simply a re-write of the John Hobby
graph macros, taking advantage of floating-point MetaPost (thus
simplified).



I have been working on a completely new luagraph module that does much
in lua. It has, notably, arbitrary coordinate systems.

This has been a moving target as I put more and more into lua
and less and less in Metapost. I have also been playing chase with the
development of luametatex (and have fallen behind).

You can set these strings in your source file, no need to have a
private copy of mp-grap.mpiv

Autoform := "@.0e" ;

or, if you want different formats for the X and Y axes:

string Autoform_X ; Autoform_X := "@.0e" ; % or whatever you want ...
string Autoform_Y ; Autoform_Y := "@.0e" ; 

A few notes:

Autoform_X and Autoform_Y are used if known, otherwise it falls back
on the string Autoform.

The format string uses "@" rather then "%", as % is normally scanned as
a comment.

Thanks Alan. I see those lines in the module listing, but could you provide
some guidance on usage? Can the (re)formatting be done from my input file,
or do I need to modify mp-grap.mpiv, or some other way?

(Apologies for double-dipping, but usage direction for the least-squares

% Autoform   is the format string used by autogrid

[NTG-context] Typo in m-tikz

[Aditya Mahajan via ntg-context]

Hi,

There is a typo in m-tikz.mkxl (possibly a carry-over from t-tikz.tex). The 
module ends with a spurious `\stopmodule`:

https://github.com/contextgarden/context-mirror/blob/fe714093ebb95e4a870282782e2124cff2e546e5/tex/context/modules/mkxl/m-tikz.mkxl#L113

(Or rather, the corresponding `\startmodule` is missing). 

This causes an interesting error message on the following test file:

\usemodule[tikz]

\usetypescriptfile[euler]
\definetypeface[mainfont][rm][serif][pagella][default]
\definetypeface[mainfont][mm][math] [pagellaovereuler][default]
\definetypeface[mainfont][tt][mono] [dejavu][default] [rscale=0.8, 
features=none]
\setupbodyfont[mainfont,11pt]

\starttext
$\dfrac{1}{2}$
\stoptext

which gives:

$\dfrac{1}{2}$

And since tikz is a latex module, in the true LaTeX spirit, the error goes away 
(for obvious reasons) if I move the \usemodule[tikz] to after the font 
definitions. It took quite a while to figure out what is happening.

[Akira Kakuto]

(Context Standalone, ver. 2017.01.27, ver.
2017.02.19) and in context from TeX Live 2016 (ver. 2016.05.17) these
two examples give identical tables that differ from results on
the wiki page.


Confirmed.
ConTeXt mkii gives results on the wiki page.

Best,
Akira

[NTG-context] Specifying the cell column: are \TD[n] and \TD[m] broken?

[Vladimir Lomov]

Hello,

on wiki page
[[http://wiki.contextgarden.net/TABLE#Specifying_the_cell_column]] there
are two examples (also I found them in tabl-ntb.mkiv) to "skip" empty
cells:

 8< -
\bTABLE[width=3em]
\bTR\bTD d1 \eTD\bTD[n=2] d2 \eTD\bTD[n=5] d5 \eTD\bTD[n=7] d7 \eTD\eTR
\bTR\bTD f1 \eTD\bTD[n=4] f4 \eTD\bTD[n=5] f5 \eTD\bTD[n=7] f7 \eTD\eTR
\eTABLE
 8< -

and

 8< -
\bTABLE[width=3em]
\bTR\bTD d1 \eTD\bTD[m=2] d2 \eTD\bTD[m=5] d5 \eTD\bTD[m=7] d7 \eTD\eTR
\bTR\bTD f1 \eTD\bTD[m=4] f4 \eTD\bTD[m=5] f5 \eTD\bTD[m=7] f7 \eTD\eTR
\eTABLE
 8< -

but in current context (Context Standalone, ver. 2017.01.27, ver.
2017.02.19) and in context from TeX Live 2016 (ver. 2016.05.17) these
two examples give identical tables that differ from results on the wiki
page.

P.S. I don't use this feature but find it very interesting and sometimes
useful.

Thank you for this insight Alan! Two results immediately helpful are:

Thank you Alan. setrange is the key I had not tried and I will be more careful 
with (2).

This may not be the proper way to ask, but it is related to the topic: how to 
get Hobby’s Figure 9 from the mpgraph manual to work using m-graph?

Re: [NTG-context] m-graph read data and plot

[Alan BRASLAU]

You have two problems:

1) gdraw (4,1)--(7,1);
has a unique ordinate, so graph will fail in this case if you do not
explicitly set the range.

2) You have to take care with your choice of loop variables in MP not
to run into conflicts those eventually used in macros. Also, as Hans
indicated, you do need to declare that a is an array, as in
numeric a[];

Here is a MWE

\enabletrackers[metapost.showlog]
\usemodule[graph]
\startMPpage[instance=graph,offset=3mm]
  draw begingraph(5cm,5cm);
numeric a[];
gdata("data.d", v,
  for j=1 upto 3:
a[j]:=scantokens v[j];
  endfor ;
  );

setrange (whatever,0,whatever,2);
gdraw (a2,a1)--(a3,a1);
  endgraph;
\stopMPpage

Thank you Hans. Do you mean numeric a[n]? It was not explicitly declared; I did 
not think it needed to be—the show commands write what I expect to the

[NTG-context] Using input maps for ITRANS to devanagari with context m-iv

[Shree Devi Kumar]

Hello All,

Xetex allows the use of input maps such as xetex-itrans for taking input in
ITRANS transliteration and converting to devanagari .

xetex-itrans package is at
   http://tug.ctan.org/tex-archive/macros/xetex/generic/itrans/
.  Information is at
   http://tug.ctan.org/pkg/xetex-itrans

I am planning to use context-m-iv for some Sanskrit documents.

Is it possible to use the input maps with Context m-iv ?

Thanks,
Shree Devi

Re: [NTG-context] Devanagari in Siddhanta font with Context m-iv

[Shree Devi Kumar]

Aditya,

sarvaartha should have the r maatraa on top of va - in case of siddhanta
font when used in ConText the maatraa is not coming instead a dot seems
visible halfway on va (I am assuming that you can read devanagari) - when
you compare with Chandas the maatraa is  clearly visible. so
सर्वार्थ is looking like सवार्थ with a dot on वा

It may be a question of correctly stacking the components for building the
vertically stacked glyph (I do not know much about font design and
rendering - this is just a guess).

Metapost now has double precision arithmetic, so one no longer needs to

z = (scantokens v1, scantokens v2);
augment.p(x,0);
augment.p(x,y);
x := x + 0.4 ;
augment.p(x,y);

[NTG-context] bar graphs, m-graph, sarith

[John Kitzmiller]

When trying to make a bar graph with m-graph.mkiv and sarith, the command Ssub 
(string subtract) seems to Sadd instead. An mwe of a bar graph:

 (data1 is a separate file containing
  01 02
  02 03)

\usemodule[m-graph]
\startMPpage[instance=graph]
input sarith;
draw begingraph(5cm,5cm);
 gdata("data1", v,
  path p;
  augment.p(v1,0);
  augment.p(v1,v2)
  augment.p(v1 Sadd "0.4",v2);
  augment.p(v1 Sadd "0.4",0);
  gfill p--cycle withcolor .8white;
  gdraw p--cycle;
  );
endgraph;
\stopMPpage

...which gives bars of width 0.4 starting at abscissa 1 and 2 as expected. To 
increase the width of the bars to 0.8 and have them centered over 1 and 2, I 
expect to Ssub from the first two augments:

\usemodule[m-graph]
\startMPpage[instance=graph]
input sarith;
draw begingraph(5cm,5cm);
 gdata("data1", v,
  path p;
  augment.p(v1 Ssub "0.4",0);
  augment.p(v1 Ssub "0.4",v2);
  augment.p(v1 Sadd "0.4",v2);
  augment.p(v1 Sadd "0.4",0);
  gfill p--cycle withcolor .8white;
  gdraw p--cycle;
  );
endgraph;
\stopMPpage

However, the Ssub adds instead and gives a line at 1.4 and 2.4.

Compiling the above with mpost or mptopdf gives the desired result(s), but I am 
curious if this can be resolved so such bar graphs could be made within 
ConTeXT/METAFUN.

Thanks! John

i patched your version a bit:

local mycsvsplitter = utilities.parsers.rfc4180splitter()

local crap = [[
first,second,third,fourth
"1","2","3","4"
"a","b","c","d"
"foo","bar""baz","boogie","xyzzy"

-- local list, names = mycsvsplitter(crap,true)
-- local list  = mycsvsplitter(crap)

the flag tells to return a header

If you have up to 9 columns, you could use

 \def\ProcessingLine#1#2#3#4#5#6#7{%
 \bTR\bTD#1\eTD\bTD#2\eTD\bTD#6\eTD\bTD#7\eTD}

and then [command=\ProcessingLine]


Well, something like 20 columns (on A4 landscape). ;)

It turns out that my method somehow doesn't work well without setting
also height=0pt; then it's fine, but I'm still wondering about a
cleaner way.


I've added a splutter to the core:

\startluacode

local mycsvsplitter = utilities.parsers.csvsplitter {
separator = ",",

local crap = [[
"1","2","3","4"
"a","b","c","d"

local mycrap = mycsvsplitter(crap)

Re: [NTG-context] "Hiding" columns in m-database & TABLE

For example, easily such files are easily manipulated using awk.

awk "{print $1,$2,$3,$5,$7}" data.csv > interesting.csv

and this can be used in a pipeline...

[NTG-context] "Hiding" columns in m-database & TABLE

[Marcin Borkowski]

Hi all,

I'd like to process a csv file (with the database module) in order to
typeset a (nice) TABLE. However, I have a few columns I'd like to
omit.  I can (of course) hand-edit the csv file; but is there a way to
do it automatically?  Something like

\setupTABLE[column][3,4,5][kill]

I did [empty=yes,width=0pt] in place of [kill], and it worked, but it
seems like a hack (and I don't know whether it does actually process
the cells I'm omitting - which in my case wouldn't bother me, but might
be an additional layer of inelegance;)).  And better ideas?

Best,

Thank you for the suggestion. Tried it, but this
doesn't work, so I must be missing something...

Of course, with MetaPost 2.0 we will certainly come across such a case
with numbers like 1e805. :)

Better to anchor the pattern to the start of the string with `^` (and
then the nonzerodigitmatching is no longer needed):
gsub("^%+*0*", "")
Otherwise, you'll get 805 --> 85.

Figured it out (and we don't want to strip a leading minus sign):

local function strip(s)
return "\\times10^{"..(s:gsub("%+*0*([1-9])","%1")).."}"

Thanks, this "fixes" it for now,
but I believe that the strip is intended to remove leading zeros, as in
  label(format("@g","1e+08"),(2cm,-1cm)) ;

I suppose that the correct syntax must be something like the regex
  s/[+-]*0*\([1-9]\)/\1/
(not sure how to state this in lua gsub()...)

[Sietse Brouwer]

The function strip() is removing 0 throughout the exponent, and I
don't know what purpose that might serve. If we never want to remove
zeroes, this works:

local function strip(s)
-return "\\times10^{"..(s:gsub("%+*0*","")).."}"
+return "\\times10^{"..(s:gsub("%+*","")).."}"
end

Note that if the exponent is zero the "× 10^0" will be left out
completely, in both the old and the new strip() function. This seems
to be by design. Illustration of this behaviour:

\usemodule[graph]
\starttext
\startMPpage
label(format("@g","1e+0"),(2cm,-1cm)) ;
\stopMPpage
\stoptext

[NTG-context] m-graph.mkiv format bug

[Alan BRASLAU]

There is a bug with format() as redefined in m-graph.mkiv
1e10 and 1e-10 truncate the tailing 0.
(I have not been able to fix the code...)

Alan

Minimal example:

\usemodule [graph]

\starttext
\startMPpage
label(format("@g","1e-10"),(0,  0)) ;
label(format("@g","1e+10"),(2cm,0)) ;
label(format("@g","1e-12"),(0,  -.5cm)) ;
label(format("@g","1e+12"),(2cm,-.5cm)) ;

[NTG-context] m-database: setting text style for every first line of a table, and text/cell style for specific parts of the table?

[Sander Maijers]

Hello everyone,

I did manage to get a background color for the first row. This is a snippet 
that I use

\defineseparatedlist
  [CSV]
  [separator=comma,
   
first={\bTR[align=middle,background=color,backgroundcolor=gray]},last=\eTR,
   left=\bTD,right=\eTD,
   before={\bTABLE[align=middle]},after=\eTABLE]

\processseparatedfile[CSV][/tmp/CSV.csv]

Also, can you think of a way to specify the cell and text style for individual 
cells with processseparatedfile?

Regards,
Sander Maijers

Admittedly I feel a bit lost when looking at the various processing

My goal is to create template based output. I have created a rough
mail-merge example (with LibreOffice) and attached it as PDF for

There is a CSV database with currently 8 fields, probably a few more
will be added. These fields need to be placed into a form, in my example
a list of courses. Other forms based on the same data should follow.
These forms/lists will then be printed.

Hope that makes sense. Maybe I'm pushing the database module a bit to
far, but I was just trying to avoid "mail-merges"...


\starttext

\startluacode

-- or: str = io.loaddata(somefile)

local str = [[

local list = string.splitlines(str)

for i=1,#list do
local fields = utilities.parsers.settings_to_array(list[i])
if fields[1] then
context("field 1: %s",fields[1])
context.par()
end
end

\stopluacode

\stoptext

so:

- read in the cvs file
- split them into lines
- loop over each line
- split that line
- and mess around with the fields

I had to look at the example in the module for this and what I saw is that you 
can only use commands with *one* but this isn’t a real problem, when you 
describe what do you want to do with the entries I can provide you with a 
solution for this.

Wolfgang, thanks, that worked for the sample code. However, when 
extended to three fields (I need 8) the field splitting gets rather messy.


Thanks, Martin


Modified code:

\usemodule[database]
\unexpanded\def\SendMe#1#2#3{#1\crlf#2\crlf#3}

\defineseparatedlist
  [Addressen]
  [separator={;},command=\SendMe]

\starttext
\startAddressen
house1;street1;name1
house2;street2;name2
\stopAddressen
\stoptext


Result is in attached PDF (hope that's ok)

[NTG-context] error with m-database example

[Martin]

Sorry to pick up an old topic 
(http://archive.contextgarden.net/message/20101221.082006.4dc83f26.en.html), 
but I seem to have the same problem with m-database at mentioned in this 
old thread.


I am trying to "freely" use the data fields in a layout other than 
(natural) Tables.


An update of context (15.2.2012) doesn't help.

The example from the CSV MyWay fails as well as the simplified example 
below with following error:



\doprocessdatabase ...ameter \c!command \!!es , }}
l.14 \stopAddressen


Modifying m-database.lua as suggested in the old thread seems to have no 
effect on the error... Though I suspect the file has been changed since 
anyhow.


Thanks for any input, Martin

Code used:

\usemodule[database]

\def\SendMe#1#2{#1\crlf#2}

\defineseparatedlist
  [Addressen]
  [separator={;},command=\SendMe]

\starttext

\startAddressen
xyz;Maasstraat
abc;sometown
\stopAddressen

\stoptext


using the variant doesn't help:

\startseparatedlist[Addressen]
xyz;Maasstraat
abc;sometown
\stopseparatedlist

Re: [NTG-context] Why does the oldstyle numerals switch, \os, also switch off m-dashes?

[Pavneet Arora]

Just for the sake of completeness, in case someone else stumbles upon this 
thread, it should be noted that \definefontfeature needs to be set before 
\setupbodyfont, i.e.,


\definefontfeature[default][default][onum=yes]
\definefontfeature[smallcaps][smallcaps][onum=yes]
\setupbodyfont[schola,11pt]

rather than:

\setupbodyfont[schola,11pt]
\definefontfeature[default][default][onum=yes]
\definefontfeature[smallcaps][smallcaps][onum=yes]

I made the mistake of using the latter form in one of my tests and was
left wondering why things weren't working.

Regards.

No, the answer is that smallcaps are activated with the “smcp” feature and this 
is applied to the regular style with the “smallcaps” set. To get now old style 
figures when you use smallcaps letters you need also this setup:

\definefontfeature[smallcaps][smallcaps][onum=yes]

Hi Pavneet,

I do not know which font/kind of font you intend to use. So provided the font 
is a otf-type the following works:

\setupbodyfont[times,rm,12pt]
\definefontfeature[oldstyle][sript=latin,onum=yes]
\starttext
\addff{oldstyle}
1234567890 A Pause---between yes and no.


1234567890 A Pause---between yes and no.

Dear Hans,

The command
\comment[r]{blabla}
does not work anymore  in mkiv when using \usemodule[chart]: one gets an error 
message. (ConTeXt  version 2011.10.19 00:02).
It seems that in the file
m-chart.mkvi
there is a typo at line 277: one finds there
\do_FLOW_commment
instead of \do_FLOW_comment. Fixing this typo eliminates the error message but 
the comment does not show up.


I've added comment to the new code but I'm not sure how compatible it 
is. However, there is more control, compare [t] (anchored at edge) with 
[t:0.5] (anchored halfway along the path) ... comments now relate to the 
connection that they follow so each connection can have a whole bunch of 
comments.

Dear Hans,

The command 
\comment[r]{blabla} 
does not work anymore  in mkiv when using \usemodule[chart]: one gets an error 
message. (ConTeXt  version 2011.10.19 00:02). 
It seems that in the file 
m-chart.mkvi
there is a typo at line 277: one finds there
\do_FLOW_commment
instead of \do_FLOW_comment. Fixing this typo eliminates the error message but 
the comment does not show up.


Best regards: OK

[NTG-context] [m-chart] Focus feature

[Marco]

Hi,

it's  me with  flow chars  again. I  didn't get  the focus
feature  to work.  The  following example  does not  focus
anything. Has the syntax changed or is the feature gone?


%%
\usemodule   [chart]
\setupFLOWfocus  [framecolor=yellow]
\setupFLOWcharts [focus=bar]

\startFLOWchart [mychart]
\startFLOWcell
\name {foo}
\location {1,1}
\shape{action} % mandatory, otherwise error
\text {Foo}
\stopFLOWcell
\startFLOWcell
\name {bar}
\location {1,2}
\shape{action} % mandatory, otherwise error
\text {Bar}
\connection [tb] {foo}
\stopFLOWcell
\stopFLOWchart

\starttext
\FLOWchart [mychart]
\stoptext
%%

Another issue: According to the manual, “action” should be
the default shape. However, when no shape is specified, an
error is raised. Is it a bug?

Regards

Marco Patzer

I see.  Thanks for  checking the  sources. That  means the
syntax is as follows:

   -tt+t
  
 +l || +r
||
  l ||  r
||
 -l || -r
||
  
   -bb+b

I added a section to the wiki.

Neither do I, I don’t use module often enough to remember syntax.

To be sure I looked for the correct input and also MkII expects
the + and - before the location of the node but MkII had “n” as
synonym for + which is now “m” in MkIV.

The order of arguments is now different in MkIV (bug?),
you have to write “tmb” or “t-p” to connect from the center
of the bottom shape the left of the top shape, the two
keywords “m” and “p” are synonyms for “-” (minus) and “+” (plus).

According  to  this, [tb+]  should  yield  to the  desired

Sorry, you need \setuppagenumbering[location=].

The “state=stop” setting isn’t the prefect solution because it stops
pagenumbering. You can see this when you replace in Adityas example
\currentpage with \pagenumber and \lastpage with \lastpagenumber.

Re: [NTG-context] Footer including "Page n of m"

I'm trying to recreate an MS Word document in ConTeXt.  The reason for this
is so the final document won't stand out from the others too much, and also
so that I can have better control over the layout.

One thing I'm having difficulty with is the footer, which consists of a
rule, followed by

"Name of document on the left << space >> Page n of m"

where "n" is the current page number, and "m" is the total number of pages
and is on the right.  Is there an automatic way of obtaining "m",



\setupfootertexts[Page \currentpage\ of \lastpage]


and what's the best way of preceding this footer by a rule?


\setupbackgrounds[footer][text][topframe=on]
