Re: [NTG-context] Invoking ConTeXt from inside php web appliction

In principle this is workable up to the point that the output PDF needs to be handed off to the user. In my case, it is the (authenticated) parent who is requesting their child’s report card in one of two forms each of which is created dynamically at any point along the school “term”. The user is waiting for the output PDF from the browser. In Laravel this is accomplished by using: return response()->download($full_output_filename)->deleteFileAfterSend(true); whereupon the end user sees the familiar Open, Save, … dialogue. But the dispatcher pattern is very useful, and I like it very much. In another area, I use it to monitor a directory for forms input, which are done off-line on W10 tablets using a browser and the Mongoose lightweight httpd, and then uploaded using sftp (under Cygwin). Thanks, again, for the suggestions. Pavneet Arora m: +1 (647) 406-6843 e: pavneet_arora(a)waroc.com From: luigi scarso

Product-component structure

Hi, This is based on a question on tex.sx: http://tex.stackexchange.com/q/316504/323 In file-job.lua, we have: local processors = utilities.storage.allocate { ... [v_product] = { [v_text] = { "many", processfilemany }, [v_project] = { "once", processfileonce }, [v_environment] = { "once", processfileonce }, [v_product] = { "many", processfilemany }, [v_component] = { "many", processfilemany }, }, [v_component] = { [v_text] = { "many", processfilemany }, [v_project] = { "once", processfileonce }, [v_environment] = { "once", processfileonce }, [v_product] = { "none", processfilenone }, [v_component] = { "many", processfilemany }, } } Then, why is the product file processed multiple times?

10th ConTeXt meeting update
by Taco Hoekwater 11 Jul '16

11 Jul '16

Hi all, It is high time I sent out some news about the next ConTeXt meeting. First off, the deadline for early bird payment happened in the middle of my vacation. An unfortunate side-effect: I completely forgot to send out a reminder to the list! Bad me! To make it up to you, we will allow an extra few days of early bird registration. All registrations done during the current week will still be considered ‘early’, as long as the bank transfer happens at the same time. The new cut-off date is therefore Sunday July 17 (I have no desire to update the web pages with the new deadline, so just ignore the July 1st date given there). After that embarrassing disclosure, here is the other information I wanted to share: * As noted before, the meeting will be held in Kalenberg, The Netherlands, from Sunday September 25 until Saturday October 1, 2016. Sunday Sep 25 and Saturday Oct 1 are the arrival/departure days, the actual meeting will be from Monday to Friday. * The theme of the meeting is “Piece of Cake” * We have a lot to celebrate: 10 years of meetings, 20 years of ConTeXt availability, and 30 years of Pragma ADE. * The website is here: http://meeting.contextgarden.net/2016 * The abstracts page has been updated with a dozen or so abstracts provided by Hans. Some of those are marked optional, which means the talk may be cancelled if there is not enough room in the final program. That is, unless there is popular demand. Have a look and see if something catches your interest! * As always, we are looking for more presentation submissions. Please have pity on Hans’ vocal cords and consider giving a talk! * Those of you who are known participants should have received a welcome message from the participants mailing list by now. If you did not get that message, something could have gone wrong with your registration, so please contact me in that case. Hoping to see many of you this autumn, Taco

Invoking ConTeXt from inside php web appliction
by Pavneet Arora 11 Jul '16

11 Jul '16

I am stuggling with getting ConTeXt to run from inside a php script under Apache. First off, let me say that the installation works fine from the command line as a logged in user. Initially, I tried to do it inline: cmd = ". /opt/context/tex/setuptex /opt/context/tex/setuptex; cd $spool_dir; context $full_input_filename"; system($cmd); which returns exit status 2, "Incorrect usage". Then I created a small bash script with the following lines: #!/usr/bin/env bash . /opt/context/tex/setuptex /opt/context/tex context $1 When I trap the output, I get the following error in the log file: resolvers | caches | fatal error: there is no valid writable cache path defined I also attempted this manually at a bash prompt resulting in the same error: sudo -u www-data bash -c bin/proccontext.sh $FILENAME What would be the correct design pattern to invoke ConTeXt from a web application? This is all under Ubuntu 14.04, BTW. advTHANKSance -- Pavneet Arora m: +1 (647) 406-6843 Waroc Informatik t: +1 (416) 937-9276

Issue with tex.hangindent with latest beta 2016-07-08 17:24
by josephcanedo＠gmail.com 10 Jul '16

10 Jul '16

Dear list, In some lua code I have in my project, I’ve started getting this error when upgrading to latest beta (used to work fine for lots of versions for months) : attempt to perform arithmetic on field 'hangindent' (a nil value) when using expression: tex.hangindent in lua code. I am quite sure hangindent is not zero for this paragraph (on purpose). Is there a change in way to access hangindent value for a paragraph ? Many thanks Best regards Joseph Canedo
