The goal of these example scripts is to export invoices to LaTeX or other output formats as desired.

Files:

latex_invoices.py

A first approach which exports invoice data to an .lco file which is subsequently included into the template
- Templates:
  - Invoice.tex
    
    File derived vom scrlttr2.tex v0.3. by Juergen Fenn.
    
    rechnung.sty is used to create the table of entries
gncinvoice_jinja.py

A second step. Imports jinja2 templates and fills in the invoices values. More flexibility in creating the output files. Output can be anything: LaTeX, HTML, CSV, XML, ...
- Templates:
  - Invoice.tex.tmpl
    
    LaTeX template using rechnung.sty, close to the one used by latex_invoices.py.
  - Invoice_2.tex.tmpl
    
    LaTeX template using a table to fill in the invoices values. No rechnung.sty required.
gncinvoicefkt.py

Some helping functions. Included by latex_invoices.py and gncinvoice_jinja.py.

Goals / Issues:

How much logic in the template, how much preprocessing in the python script ?
Internationalization - currencies, formatting of numbers, templates
Providing data of gnucash owner.

At the moment this has to be put into the invoices (template/final file) by hand. Access of this data is in KVPs. No support in python-bindings at the moment. c-API to access these values is work in progress. A fork to access these is https://github.com/c-holtermann/gnucash/tree/python-kvp. This is very much work in progress. A discussion can be found in thread https://lists.gnucash.org/pipermail/gnucash-devel/2014-June/037768.html.
