gnucash | Clone of Gnucash project

My perl script, z.pl, uses Time::Local qw( timelocal_posix timegm_posix ); and File::Rsync. (You will find z.pl at the bottom of this post.)

Currently I work on a macbook pro under macOS Catalina 10.15.7. But I want my code to be portable, so that in the future, if I move my files to a different machine or operating system (or at least another *nix), the code will not need fixing --- other than a possible change in the source and destination paths. To this end, my usual shebang is #!/usr/bin/env perl.

To have access to Time::Local qw( timelocal_posix timegm_posix ); I had to install an up-to-date version of perl. (For this, I used homebrew.) This is because the perl that comes loaded on my macbook pro is antiquated. We see the difference here:

History: I have been using GNUCash for Accounting and it stores all customer information so to integrate Job Delivery of files and invoices i was integrating GNUCash database on Postgres with the existing local server to send and backup files and mark them automatically.

So i did inspectdb> models.py and got all the models from gnucash database. Now 'Customers.objects.all()' is working file and gives list of all the data but 'Customers.objects.get()' doesn't work and gives error.

I'm trying to build a python wrapper for gnucash c++ parts. In QofBackend I encountered the method const std::string && get_message (). In python this message returns instead of a string as in my setting as there is no swig typemap for std::string rvalue reference.

I didn't really find a simple explanation so I rebuilt an example setting and dug into c++ which I barely know. I managed to get the string into python but I'd like to know

• if this typemap(out) approach is correct (also in respect of memory and error handling).
• The conversion in set_s_workaround() is also just a workaround. I don't think that for gnucash the python code ever needs to set this value but for completeness sake it would be nice to also have a typemap(in) std::string&& and
• get rid of get_s_workaround
• get init_s_2 working.

I have an xml file that has elements that look like gnc:account (it's a gnucash accounts file). I want to find all elements with that name.

However, if I do this;
