[NTG-context] Cannot Install Win Minimals: rsync.exe
Hello, I have just encountered a problem with the Windows minimals. I downloaded the current version today and ran first-setup.bat. The installation failed and reported that cygiconv-2.dll was missing and that rsync.exe could not work without it. So I went to the official cygwin site and got the file myself. When I ran first-setup.bat again, the program reported that something was missing from cygwin1.dll and that rsync.exe still could not run. Has something changed in the minimal installation package in the last few days? This has never happened before. Thank you. ___ 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 : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___
Re: [NTG-context] Loading lua file.
Hello,
I'm using this if loading failure is not fatal:
DoFile = function(fn)
return pcall(function() return dofile(fn) end)
end
DoFile(MyFile.lua) -- instead of 'dofile(MyFile.lua)'
You can play with handling error code
(http://www.lua.org/manual/5.1/manual.html#pdf-pcall):
DoFile = function(fn)
local suc, res = pcall(function() return dofile(fn) end)
if suc then return res
else
-- Your handling code to come here
end
end
Best regards,
Lukas

Hello, Philipp!
If I load a lua file from a module using
\registerctxluafile{file}{1.001}
or
\ctxloadluafile{file}
How can I be sure the file was in fact loaded?
The related tracker output is quite comprehensive:
\enabletrackers[resolvers.locating]
\ctxloadluafile{sometest}
Nice! Thank you.
In my case, it was not being loaded because I had syntax errors in the
lua file. The file was found, but not loaded. I guess it is a very
good reason to halt!
Cheers,
André Caldas.

Re: [NTG-context] New module: simplesteps.
Hello!
thanks for the interesting contribution! Have a look at the patch
I hopefully don’t forget to append.
Thank you! I will take a look and learn... ;-)
[...]
I use \startbuffer and \stopbuffer, and also Lua. As I said, I don't
really know how to write a module... comments are very welcome.
Honestly, it doesn’t work, but that’s a minor flaw!
Sorry! I forgot to mention. Only a little subset of it works. I have
(already - so I don't forget to) attached a tex file that works.
[**lots of advices I will study carefully latter**]
[...]
I could not figure out how exactly the section block thingy is
supposed to work. It does not create the \startframe macro at all
-- is this something custom?
I don't know how to use this startframe yet. So, I am doing like
this right now: (numbers like 2-3 or 2- don't work yet)
=== START code snip ===
\startbuffer[simplesteps]
\startitemize
\item First item
\uncover[2,3,4]{\item Second item}
\uncover[3,4]{\item Second item}
\uncover[4]{\item Second item}
\stopitemize
\stopbuffer
\simplestepsplaybuffer
=== STOP code snip ===
The simplestepsplaybuffer macro simply calls the
simplesteps.playbuffer() lua function. This function plays the buffer
and determines if it has to be played again or not. If it does, then
it tex.print('\simplestepsplaybuffer').
The macros uncover determine how far the specification is from being
played. If it is being played now, then show. If it is played next,
then show in gray. And so on.
I infer it’s about the slide title
so I have \startframe call \section but that should be taken as a
placeholder at most. In my own slide module I use
\{start,stop}section with the option placehead=no and rely on the
page header to display the slide title (i.e. current section
running head). That was the laziest way I could imagine :P
I guess that's what I want to do. I just don't have the necessary
knowledge yet. ;-)
Some remarks:
- you should rename simplesteps.mkiv to t-simplesteps.mkiv,
indicating that it is a thirdparty module
I will. I think I will have a bitbucket repository exclusively for
modules. Then I will have the proper directory structure, the proper
naming scheme and hopefully proper documentation, xml, etc. (lots of
things to learn!)
- if you plan on expanding the code you eventually will come to
love this bit: http://wiki.contextgarden.net/System_Macros
- Context has a namespacing system which you might consider
switching to in the long term:
http://tex.stackexchange.com/q/58654
but it’s arguably an advanced method
Well, I do want to do it the right (recommended) way!
- maybe switch to mkvi as named parameters make rewriting
macros a breeze
Would you elaborate a bit further?
Is it ok if I send a PDF sample to the list?
I hope you can use the TEX file attached.
Cheers,
André Caldas.

[NTG-context] Count the words per line
I am setting with grid-set, and I am wondering, if there is a possibility to count the number of words in the lines (not for each single line, but in average over all lines). That would be helpful to get a perfectly readably book (words per row is one of these readability-measures). That tool could ignore hyphenated words at the end of a line, or count it with 0.5, or whatever.

You can use for the parameter in your macros names instead of number,
as you can see below the first definition uses “#1” for the argument while
the second uses “#text”.
You can force MkIV mode when you add “% macros=mkvi” at the top
of the file. When your code is a external file (e.g. a module) you can
give it “mkvi” as file extension (instead of the normal “tex” or “mkiv”)
and don’t need this line anymore.

% macros=mkvi
\def\mkivhighlight#1{{\red #1}}
\def\mkvihighlight#text{{\green #text}}
\starttext
\mkivhighlight{MkIV}

The file extension/first line is necessary because TeX itself still expects
numbered
parameters and context has to convert the names to numbers before TeX sees them.
To know when such a conversion is necessary the file extension is a hint for
context.
I have one question:

No you don’t have to but you could have checked yourself :)

You’re trying to pass a single to Lua which doesn’t work because you use
in your Lua code for the string.
When you change your definition for \uncover to
\unexpanded\def\uncover[#1]%
{\ctxlua{
distance = simplesteps.distance_to_step(\!!bs#1\!!es)
...
}}
it works because the is now only part of the string.

These expand to Lua long strings, [===[ and ]===] respectively,
without checking, so theoretically the same issue will arise iff
your string contains ]===]. I consider the likelihood for this to
happen to be too low to bother, but if you want to be absolutely
on the safe side you can also use \luaescapestring. See the
Luatex manual, section 2.3.6.

Re: [NTG-context] Cannot Install Win Minimals: rsync.exe

The installation failed and reported that cygiconv-2.dll was missing ... Has something changed in the minimal installation package in the last few days? This has never happened before. I rewrote the scripts and switched to a different server for the distribution on 30th November. The reported problem must have been a slight oversight that nobody noticed so far. I hope that it is fixed now, but I didn't test if it works.

Re: [NTG-context] New module: simplesteps.

thanks for the interesting contribution! Have a look at the patch
I hopefully don’t forget to append.
I didn't quite understood how this works:
\unexpanded\def\startframe{\dosingleempty\frame_start}
This creates the new command \startframe which calls the internal command
\frame_start which has one optional argument.
\def\frame_start[#1]{%
\iffirstargument
\section{#1}%% solution needed here!
\fi
This block checks if the optional argument is used by the user, when the
argument is used the content is typeset as \section.
\begingroup
\grabbufferdata[simplesteps][startframe][stopframe]%
}
With the \grabbufferdata command the content beginning from \startframe until
\stopframe is stored in a buffer with the name “simplesteps”.
\let\stopframe\simplestepsplaybuffer
This makes the \stopframe command a synonym for \simplestepsplaybuffer which is
now called when the frame environment ends.
