[NTG-context] Different layout for specific pages
Dear list, I would like to specify in advance that certain pages are to have different layouts. I put together an example based on what read on the wiki (https://wiki.contextgarden.net/Layout#Multiple_layouts): \setuppapersize[A6] \definelayout[bigheader][header=0.5\textheight] \definelayout[smallheader][header=0.1\textheight] \setuplayout[smallheader] \definelayout[1][bigheader] \definelayout[2][smallheader] \starttext \showframe \input knuth \input knuth \input knuth \stoptext However, rather then having the big header only on page 1, I end up with it on every page except page 2. Is this a bug or can someone tell me what I'm doing wrong? I've tried using the lmtx binaries, a recent context standalone version (2019-08-17) and using context live with the same result everywhere.

Dear list,
As the subject line states, I am looking for a means of retrieving a
table of all saved buffer names from lua. A MNWE would looks like:
It's not so easy because ConTeXt stores the buffers in a local variable
`cache` which is an upvalue for all the other functions. However, you
can use the Lua `debug` library to access upvalues. I access the first
upvalue of `buffers.erase`, because it only has a single upvalue which
is `cache`. Then I can easily extract all the names from that. You
can't get them in the order of declaration because `cache` is a hashmap
and not an array. Moreover, ConTeXt is usually in sandboxing mode. To
get access to the `debug` library you have to run ConTeXt with
context --debug test.tex
MWE:
\starttext
\startbuffer[ex1]
Buffer 1
\stopbuffer
\startbuffer[ex2]
Buffer 2
\stopbuffer
% Should return {ex1, ex2} or similar
\startluacode
local _, cache = debug.getupvalue(buffers.erase,1)
local names = {}
for name,_ in pairs(cache) do
names[#names+1] = name
end
context(table.concat(names,", "))
\stopluacode
\stoptext
That's perfect, thank you! I did see the cache variable in buff-ini.lua
but didn't realize it was being used as an upvalue in a closure. Is
there a specific reason for using the --debug flag rather than just
loading the debug module directly in the code? The following seems to
work without the --debug flag but I want to make sure I'm not causing
some sort of side effect.
\starttext
\startbuffer[ex1]
Buffer 1
\stopbuffer
\startbuffer[ex2]
Buffer 2
\stopbuffer
% Should return {ex1, ex2} or similar
\startluacode
local debug = require('debug')
local _, cache = debug.getupvalue(buffers.erase,1)
local names = {}
for name,_ in pairs(cache) do
names[#names+1] = name
end
context(table.concat(names,", "))
\stopluacode
\stoptext
\starttext
\startbuffer[ex1]
Buffer 1
\stopbuffer
\startbuffer[ex2]
Buffer 2
\stopbuffer
% Should return {ex1, ex2} or similar
\ctxlua{context(...)}
\stoptext
The underlying idea is to store a large number of example problems in
individual buffers that could be retrieved either by specific name or as
a complete list. I'm having a problem with the latter as it seems like
all the lua buffer commands I've encountered assume that buffer names
are known in advance:
buffers.getcontent(b)
buffers.raw(b)
buffers.getlines(b)
buffers.erase(b)
buffers.assign(b, text, catcodes)
buffers.append(b, text)
buffers.exists(b)
buffers.collectcontent(names, seperator)

Re: [NTG-context] Can anyone connect context to R or python?
On 2018-10-06 02:06 PM, Aditya Mahajan wrote: I also want to take this opportunity to express my views on intefacing with external programs. The file based interaction provided by the filter module is okay for small projects but it is not ideal. Slightly better is to use pipes (popen to a REPL) or use FFI (e.g https://adityam.github.io/context-blog/post/interfacing-with-julia), but neither of these is easy to implement and needs to be done on a per-language basis. Henri Menke had a Tugboat article on this as well. In my opinion, a better long-term option is to write a jupyter client in lua that can be called by context. Then we can easily interface with all languages that provide a jupyter kernel (https://github.com/jupyter/jupyter/wiki/Jupyter-kernels). The interface of a jupter-client is available here https://jupyter-client.readthedocs.io/en/stable/index.html. It seems relatively straight forward (send a JSON message and receive a JSON message). Translating the JSON messages to ConTeXt should also be easy. Is there anyone who wants to play around trying to implement this? I have recently come across the SciLua project (http://scilua.org/index.html) which has a built-in LuaJIT client for Rserve (http://scilua.org/rclient.html) and may be relevant to the discussion. Although it certainly isn't as general as something like jupyter, leaning on SciLua may be an easier means of getting access to scientific computation with R and basic numerical methods. I am personally planning to look into switching from filter to SciLua if it means that I can get more efficient data transfer between R and ConTeXt. But I'm a ConTeXt and Lua neophyte so I doubt my personal efforts will be translatable into something more general like a module.

Re: [NTG-context] Modifying bibliography entries using lua
Thanks Hans, that's really helpful!
This is not for the fainthearted so here we go
\startluacode
function document.MyBoldPub(set,tag)
-- local a = publications.getfield(set,tag,"author")
-- inspect(a)
-- local c = publications.getcasted(set,tag,"author")
-- inspect(c)
if c[1].surnames[1] == "Myname" then
context.bold(function()
context.btxflush('author')
end )
else
context.btxflush('author')
end
end
\stopluacode
So if I wanted to bold one specific author in a reference of many, I can
just loop over publications.getcasted(...), and print the appropriate
names, initials, etc...
That said -- is there any way to call the appropriate authorconversion
routine based on the \setupbtx settings? I found the
publications.authorhashers method table, which seems to do most of this
work, but I'm not sure how to pick the appropriate method and ensure
that the correct separators are used.

[NTG-context] Modifying bibliography entries using lua
Dear list,
I'm struggling to output bibliography entries into lua for string
modification (like making a particular author name bold). In effect, I
just need something like the following:
\starttexdefinition btx:customauthor
\startluacode
local text = context.btxflush('author')
-- tex.sprint(text) -- fails because text remains nil
\stopluacode
\stoptexdefinition
It's clear that btxflux is the wrong function for this as it writes the
contents to file rather than returning a variable in lua... Is there a
way to directly access what btxflush is writing through the publications
table or other means? I've gone over the source code but I can't
decipher what btxflush is actually doing.
Thanks,
Stan

[NTG-context] Finding lua file for module using \registerctxluafile
Dear list,
I've recently written a small module p-mymod.tex which uses lua code in
p-mymod.lua. In order to load this lua code, I use
\registerctxluafile{p-mymod}{1.001} (copying the example of
m-database.mkiv). However, it seems like the search path for lua files
isn't the same as for context module files.
When a context file that uses p-mymod through \usemodule[mymod] is
placed in a subdirectory, it finds p-mymod, but not the lua portion:
p-mymod.tex
p-mymod.lua
subdir/test.tex
Placing the lua file inside the subdirectory resolves this problem:
p-mymod.tex
subdir/p-mymod.lua
subdir/test.tex
What is the suggested method to change the lua search path? Ideally, I'd
like to avoid placing the files in
$TEXMF/tex/context/third// as this module is quite
intimately tied to the specific project and it doesn't make much sense
to separate the files too much.
Thanks,
Stan

[NTG-context] mtxrun fails to install fonts
Dear list, I have what seems to be an OS- or ConTeXt version-specific issue with mtxrun installing fonts. I've been trying to add new truetype fonts (specifically Archivo ttf files) on Arch Linux using the following command: export OSFONTDIR=~/.fonts//; mtxrun --script font --reload And I've been using the following to check the installation: mtxrun --script font --list --all --pattern=*archi* It seems like a relatively new version of ConTeXt on Arch Linux (2018.04.04 00:51) recognizes but does not install the ttf files located in ~/.fonts/. The (shortened) output is: fonts | names | identifying system font files with suffix 'ttf' fonts | names | globbing path '/home/stanislav/.fonts/**.ttf' fonts | names | identifying system font files with suffix 'TTF' fonts | names | globbing path '/home/stanislav/.fonts/**.TTF' fonts | names | 8 system files identified, 0 skipped, 0 duplicates, 8 hash entries added, runtime 0.006 seconds But when I check the installation, no Archivo files are found. Strangely, an older installation on Linux Mint (2015.05.18 12:26) has no problems with the same ttf files: fonts | names | globbing path '/home/stanislav/.fonts/**.ttf' fonts | names | identifying system font files with suffix 'TTF' fonts | names | globbing path '/home/stanislav/.fonts/**.TTF' fonts | names | 8 system files identified, 0 skipped, 0 duplicates, 8 hash entries added, runtime 0.000 seconds And the check: mtxrun --script font --list --all --pattern=*archi* archivo archivomedium /home/stanislav/.fonts/typecatcher/Archivo_500.ttf archivobold archivobold /home/stanislav/.fonts/typecatcher/Archivo_700.ttf archivobolditalic archivobolditalic /home/stanislav/.fonts/typecatcher/Archivo_700italic.ttf archivodemi archivosemibold /home/stanislav/.fonts/typecatcher/Archivo_600.ttf archivoitalic archivoitalic /home/stanislav/.fonts/typecatcher/Archivo_italic.ttf archivomedium archivomedium /home/stanislav/.fonts/typecatcher/Archivo_500.ttf archivomediumitalic archivomediumitalic /home/stanislav/.fonts/typecatcher/Archivo_500italic.ttf archivonormal archivoitalic /home/stanislav/.fonts/typecatcher/Archivo_italic.ttf archivoregular archivoregular /home/stanislav/.fonts/typecatcher/Archivo_regular.ttf archivosemibold archivosemibold /home/stanislav/.fonts/typecatcher/Archivo_600.ttf archivosemibolditalic archivosemibolditalic /home/stanislav/.fonts/typecatcher/Archivo_600italic.ttf I've been searching for a couple of days and I'm at a loss.

Re: [NTG-context] definenote and localfootnotes

[NTG-context] definenote and localfootnotes
Hi,
I'm not sure if this is a bug or feature, but I noticed that custom
footnotes defined through \definenote do not appear when using
\placelocalfootnotes as per the following example:
%
\setuppapersize [A5]
\definenote [noteone] [footnote]
\setupnotation [noteone] [style=bold, headstyle=bold]
\setupnote [noteone] [textstyle=bold]
\starttext
\startlocalfootnotes
Testing footnote \footnote{this is a footnote}
Testing noteone \noteone{this is noteone}
\placelocalfootnotes
\stoplocalfootnotes
Testing footnote \footnote{this is a footnote}
Testing noteone \noteone{this is noteone}
\stoptext
%
Both the local and global footnotes appear as 1, 2 (so noteone is
numbered locally). Is there an alternative command to
\placelocalfootnotes that I can use to make noteone appear in the local
context?
Thanks,
Stan
