[NTG-context] further experiments with lua
Hi Hans, I'm doing some further experiments with the utf and lpeg libraries. This code fails, and I don't understand why: local s = "Ä" print(characters.uccode(s)) mtxrun --script test.lua ./test.lua:3: attempt to index global 'characters' (a nil value) Thomas ___ 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://context.aanhet.net archive : https://bitbucket.org/phg/context-mirror/commits/ wiki : http://contextgarden.net ___
Re: [NTG-context] issue: multiple viewer layers
You're right, my example was broken. With \stops it works as intended, as does your example.

Re: [NTG-context] Get list of all buffer names from lua

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:
\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)
be aware of the fact that such a list would also include buffers not
created by you (ones that the system uses)

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. Interesting... Actually it should not work, because this way you can escape the sandboxing. I guess Hans will fix that in the future, so you shouldn't rely on that. @Hans: To disable debug completely you should add `package.loaded["debug"] = nil` somewhere. we never disable it completely (we keep the traceback for instance) but indeed we also need to adapt loaded Hans - Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl - ___ 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://context.aanhet.net archive : https://bitbucket.org/phg/context-mirror/commits/ wiki : http://contextgarden.net ___
