        About
        -----
        
        **gcinvoice** generates invoices from Gnucash XML files using templates.
        
        gcinvoice (https://foss.heptapod.net/accounting/gcinvoice) is a tool to parse Gnucash XML data
        files, and create invoices from this data using templates. It is similar to
        g2latex (http://stefans.datenbruch.de/gnucash/gc2latex.shtml) by Stefan
        Tomanek, but the latter was not powerful enough for my needs, and did somehow
        not work for me.
        
        Features of gcinvoice:
        
        * works with data files from Gnucash starting with version 2.0, tested up
          to Gnucash 3.1.
        
        * does *not* need the gnucash python bindings, but reads the Gnucash
          XML-file directly from python.
        
        * powerful templating; not only latex, but arbitrary templates can be used.
        
        * full support for discount and taxes, but **warning**:
        
          In my opinion, POSTTAX discounts in Gnucash are not very useful, see
          bug https://bugs.gnucash.org/show_bug.cgi?id=520547  in the Gnucash bug
          database. As long there is not an option in gnucash to calculate
          tax included discounts a better way, gcinvoice abuses POSTTAX to calculate
          the taxes the way I think it should be, and thus gives a different result
          for invoices with such discounts. If such discounts occure in a invoice
          generated by gcinvoice, a warning is generated.
        
        * needs only a working Python version 2.7 or 3.x installation (tested with 2.7
          and 3.4). There are no external requirements, apart from the future module if
          running with python 2.7.
        
        * can be run standalone, or easily integrated into python applications.
        
        * gcinvoice is free software.

        gcinvoice was written by Roman Bertle <bertle@smoerz.org> 2007-2008. It
        contains an adapted version of YAPTU, a templating utility written by Alex
        Martelli (ActiveState python Cookbook recipe 52305). gcinvoice has been
        refactored and ported to python3 by Fabian Köster 2017, and rewritten by
        Roman Bertle in 2018.

        Hosting
        -------
        
        Thanks to the people at `Octobus <https://octobus.net/>`_ and `CleverCloud <https://clever-cloud.com/>`_
        for providing the repository / issue tracker hosting, as well as the development of `Heptapod <https://heptapod.net/>`_
        
        Installation
        ------------
        
        The only prerequisite of gcinvoice is a working installation of Python.
        For python 2.7, package 'future' has to be installed. For python 3.x, no
        additional packages are needed.
        
        Installation using pip
        ~~~~~~~~~~~~~~~~~~~~~~
        
        gcinvoice can be installed using pip from https://pypi.org/::
        
          python -m pip install gcinvoice
        
        See the python installation documentation for options
        (https://packaging.python.org/tutorials/installing-packages).
        
        Building from source
        ~~~~~~~~~~~~~~~~~~~~
        
        For building from source, download the sdist using pip from https://pypi.org/::
        
          python -m pip download --no-binary gcinvoice
        
        Install the build dependencies, if not already installed::
        
          python -m pip install setuptools wheel
        
        Untar the file and enter the directory::
        
          tar xvfz gcinvoice-X.Y.Z.tar.gz
          cd gcinvoice-X.Y.Z
        
        Build a wheel::
        
          python setup.py bdist_wheel
        
        Install the wheel using pip::
        
          python -m pip install dist/gcinvoice-*.whl
        
        
        Testing
        -------
        
        From the unpacked source directory, various tests can be run after
        gcinvoice have been installed. To this end change into the 'tests'
        directory and run e.g.::
        
          python test.py
        
        There might be a warning about a missing locale 'de_DE.UTF'; this special
        locale is used to test formatting of currency and quantity values. If it is
        not available, these tests are not performed, but this does not indicate any
        further problems. One test (testScriptrun) might also fail if you have
        already installed a global /etc/gcinvoicerc or a $HOME/.gcinvoicerc, or have
        a changed gcinvoicerc in the directory you run the test from, because it
        assumes the default settings of gcinvoice.
        
        If package 'pytest' is installed, the tests are nicer run by::
        
          python -m pytest test.py
        
        If tox is installed, testing for multiple python versions can be done
        quickly::
        
          tox -e py27,py36,py37
        
        Usage
        -----
        
        There are two ways to use gcinvoice. First, it can be run as a
        stand-alone script by simply executing it. Installing gcinvoice provides
        a script 'create_gcinvoice'. The help message can be got typing::
        
          create_gcinvoice --help
        
        An example for running gcinvoice as a script::
        
          create_gcinvoice -t mytemplate.tex  -o out.tex 13
        
        This uses the invoice with id '13' to fill out the template 'mytemplate.tex'
        and put the result into 'out.tex'. The gnucash data file is inferred in this
        example from the configuration files, as described in the next section.
        
        Another way is to import gcinvoice from your python session::
        
          import gcinvoice
        
        See the docstring of gcinvoice.Gcinvoice for further information.
        
        Configuration
        -------------
        
        gcinvoice reads configuration files from the following places:
        
        * /etc/gcinvoicerc
        
        * $HOME/.gcinvoicerc
        
        * ./gcinvoicerc
        
        and all files given to gcinvoice as a configuration option. The format of
        the configuration files is defined by the python standard library module
        'ConfigParser'; the file 'gcinvoicerc' in folder 'tests' of the source
        distribution of gcinvoice is a well documented sample configuration file
        which can be adapted for your needs.
        
        Templates
        ---------
        
        gcinvoice uses a template file to generate invoices from the parsed
        Gnucash data. The templating engine 'YAPTU' is built into gcinvoice, for
        detailed information see
        http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/52305.
        In short, the template file can contain python statements, and python
        expressions identified by (configurable) regular expressions. There is
        no restriction on the used python code, hence be careful, a malicious
        template could execute any code.
        
        The source distribution of gcinvoice contains an example template file
        'tests/invoice_template.tex'.
        
        By default, python expressions are written as @{}, where the expression
        is inside the curly brackets. Below are the defined variables extracted
        from the Gnucash data file, with there type indicated. These variables
        can also be None if not found in the Gnucash data file. The type
        'formatted' is special: For each of such a variable 'x', there is a
        variable `x_`, which is a decimal.Decimal instance. The variable 'x' is
        the value formatted as a string according to the configurated settings.
        
        ::
        
          guid        -- The guid of the invoice (string).
          id          -- The id of the invoice (int if possible, else string).
          billing_id  -- The billing_id of the invoice (string).
          owner       -- The owner (customer or vendor) of the invoice (dict).
          job         -- The job of the invoice (dict).
          date_opened -- The open date of the invoice (Date).
          date_posted -- The post date of the invoice (Date).
          terms       -- The terms of the invoice (dict).

          amount_gross -- The total gross amount of the invoice (formatted).
          amount_taxes -- The total amount of taxes of the invoice (formatted).
        
        In addition these useful functions and classes are provided::
        
          _currencyformatting -- A function to format monetary values.
          _quantityformatting -- A function to format other quantities.
          cformat -- The function to format monetary values as used by gcinvoice.
          qformat -- The function to format other quantities as used by gcinvoice.
          Decimal -- The decimal.Decimal class.
        
        The dict 'owner' contains data of the customer or vendor::
        
          guid        -- The guid of the owner (string).
          id          -- The id of the owner (int if possible, else string).
          name        -- The name of the owner (string).
          address     -- The address of the owner (list of strings).
          email       -- The email of the (string).
          full_name   -- The full name of the (string).
        
        The dict 'job' containes::
        
          guid        -- The guid of the job (string).
          id          -- The id of the job (int if possible, else string).
          name        -- The name of the job (string).
          reference   -- The reference of the job (string).
          owner       -- The owner (customer or vendor) of the job (dict).
                         The owner of the invoice is also accessible directly
                         in variable 'owner', see above.
        
        The dict 'terms' contains::
        
          guid        -- The guid of the terms (string).
          name        -- The name of the terms (string).
          desc        -- The description of the terms (string).
          due-days    -- The due days of the terms (string).
          disc-days   -- The discount days of the terms (string).
          discount    -- The discount of the terms (Decimal number).
        
        'entries' is a list of dicts, where amount_net, amount_gross and
        amount_taxes are amounts after applying the discount::
        
          guid        -- The guid of the entry (string).
          date        -- The date of the entry (Date).
          entered     -- The datetime of entering of the entry (DateTime).
          description -- The description of the entry (string).
          action      -- The action of the entry (action).
          qty         -- The quantity of the entry (formatted).
          price       -- The price of the entry (formatted).
          amount_raw  -- The amount of the entry as entered into Gnucash,
                i.e. qty x price (formatted).
          amount_net  -- The amount of the entry without taxes (formatted).
          amount_gross -- The amount of the entry including taxes (formatted).
          amount_taxes -- The amount of the taxes for the entry (formatted).
          amount_discount -- The amount of the discount for the entry (formatted).
                for POSTTAX, this is the gross discount, else its the net discount.
          discount    -- The discount of the entry (Decimal number).
          discount_type -- The type of the discount (DISCOUNT/VALUE) (string).
          discount_how -- Taxing of the discount (PRETAX/SAMETIME/POSTTAX) (string).
          taxable     -- Flag if the entry is taxable (int).
          taxincluded -- Flag if the tax is included in amount_raw (int).
          taxtable    -- Tax table for the entry (dict).
        
        The dict 'taxtable' contains::
        
          guid        -- The guid of the taxtable (string).
          name        -- The name of the taxtable (string).
          percent_sum -- Sum of percent entries of the taxtable (Decimal number).
          value_sum   -- Sum of value entries of the taxtable (Decimal number).
        
        Python statements are identified by default by lines in the template
        starting either with '%+', '%-' or '%='. The first one is for start
        statements like 'for e in entries' or 'if ...', the second one marks
        usually empty lines ending a python 'if' or 'for' construct, and the last
        one is for continuations like e.g. 'else'.
        
        Be aware that a template file must be encoded either as ascii or UTF-8.
        
        Issues
        ------
        
        * Because templates can contain arbitrary python expression, malicious
          templates could execute code with the permissions of the user.
        
        * I think that the calculation on POSTAX discounts is not useful in Gnucash
          (see bug report https://bugs.gnucash.org/show_bug.cgi?id=520547). gcinvoice
          calculates such discounts in invoices in a way which is more useful, but
          unfortunately still missing in Gnucash. Hence the result differs for
          invoices with such discounts from the Gnucash result.
        
        Possible Improvements
        ---------------------
        
        * After porting to python3, one test does not work any more and is skipped
          for now.
        
        * rewrite gcinvoice using a functional instead of an object oriented style.
        
        * Implement accessing not only XML-files, but also the database backends of
          Gnucash.
        
        * After python2.7 is obsolete, remove python 2 compatibility.
        
        * Testing on windows
        
        * Alternative templating engines like jinja2.
