[NTG-context] Django: using ConTeXT mkiv to output PDF

2018-01-24 Thread kaddour kardio 
i have a small Django app  to
manage my patients data, and use LaTeX to output reports. It consists un a
*parent* model called Patients and child models Consultation , StressEcho and
so on. With LaTex this works without problems

def courrier_pdf(request, pk2, pk1):
entry = Courrier.objects.get(pk=pk2)
source = Patient.objects.get(pk=pk1)
context = dict({'courrier': entry, 'patient': source})#buffer =
BytesIO()template = get_template('courrier/courrier.tex')
rendered_tpl = template.render(context,
request).encode('utf-8')#Python3 only. For python2 check out the
docs!with tempfile.TemporaryDirectory() as tempdir:
  # Create subprocess, supress output with PIPE and
  # run latex twice to generate the TOC properly.
  # Finally read the generated pdf.
for i in range(2):
process = Popen(
['xelatex', '-output-directory', tempdir],
stdin=PIPE,
stdout=PIPE,
)
process.communicate(rendered_tpl)
with open(os.path.join(tempdir, 'texput.pdf'), 'rb') as f:
pdf = f.read()
r = HttpResponse(content_type='application/pdf')
r.write(pdf)return r

i tried with this view in order to use ConTeXT but without success

def courrier_mkiv(request, pk2, pk1):

entry = Courrier.objects.get(pk=pk2)
cource = Patient.objects.get(pk=pk1)
context = dict({'courrier': entry, 'patient': cource})# buffer =
BytesIO()template = get_template('courrier/courrier.mkiv')
rendered_tpl = template.render(context, request).encode('utf-8')with
tempfile.TemporaryDirectory() as tempdir:
process = Popen(['context', '--result', tempdir],
stdin=PIPE,
stdout=PIPE,
)
process.communicate(rendered_tpl)
with open(os.path.join(tempdir, 'textput.pdf'), 'rb') as f:
pdf = f.read()
r = HttpResponse(content_type='application/pdf')
r.write(pdf)return r

My feeling is that the problem is in the workspace since i get logfiles in
the root of my app Here is log file from ConTeXT:

open source > level 1, order 1, name '/home/kaddour/context/tex/texmf-
context/tex/context/base/mkiv/cont-yes.mkiv'

l.8 }

I tried this in my view

os.chdirw(tempdir)

just before process without success.

My guess is that ConTeXT option --result= does not behave exactly like
LaTeX's -output-directoryAny help is welcome i really need ConTeXT for my
work and this problem is driving me mad!

I think you can get rid of that horizontal space by adding "offset=overlay"
to the framed environment used in your \ChapterCmd.

Thank you, but those existed only in an old version.
Current is:

\define[2]\ChapterCmd{%
  
\framed[width=\textwidth,frame=off,align=flushleft,style=\ChapterTitleFont]{#2}%
 without framed it’s a hbox?
  \setlayerframed[rightmargin]%
  [frame=off,width=\outermarginwidth,y=0mm,setups=Subtitle,align=flushleft]%
  {\structureuservariable{subtitle}}%
}

And the indent is still there.

Untested, but you have two spurious spaces in your code

\define[2]\ChapterCmd{%
  \inouter{\framed[frame=off,align=flushleft]{%

But author/subtitle still don’t show up in the ToC.
Use the \doiftext check or replace \structurelistuservariable (which is 
never empty because
it is tagged) with \rawstructurelistuservariable (which isn’t tagged and 
contains only the content

of the variable).

Aaargh, I’m blind, sorry, I changed only half of the occurrencies.

Everything’s ok now, _if_ author and subtitle are defined.

But \structurelistuservariable{something} seems to be never empty in the sense 
of \ifempty - I get those \crlf also for chapters without i.e. where I didn’t 
define those or set them to {}.

You’re still using the wrong command to print the variables.

Thank you for the reminder, I should use this more often.
Of course it found a few errors, and now the book runs through.
It’s strange that ConTeXt only stopped at \stoplines.
