Hello,

I'm exploring the Python customization possibilities of Serna. Although I've been studying the source code of the supplied plugins, I'm new to both Serna and Python.

What development/debugging methods are most helpful? Text editor and pdb? Others?

I'd like to perform stack traces, set breakpoints, etc.

Regards,

John

The important tip, and it is not obvious, is to restart Serna when you have modified the source code of your plugin, otherwise the changes will have no effect. Reloading the document is not enough.

As for debugging, personally I use "print" as a best debugger

Hi Timofey,

I know that the print statement can be my friend, but there are cases when I'd rather not have to instrument my code to perform basic operations such as setting breakpoints, single-step, step-into, step-out, etc.

Even though you prefer the print statement, I just wanted to know if you can tell me if the pdb package indeed does work in Serna's environment. I looks like I can import the package, but when I tried a few pdb commands, it just hangs Serna.

Regards,

John

I don`t use pdb, maybe it waits for some user input and thus hang Serna.
By the way, in a day or two Serna Free will be available as an open source software, so you will be able to trace the problem.

Timofey,

Two questions:

(1) Will the Enterprise version also be open source or just the free version? From your banner announcement on your website, it only mentions the Free version.

(2) What type of development environment/language is used for the core Serna modules?

There's an alternative to pdb, called winpdb. It has a mode for attaching to embedded Python interpreters. I'll give it a try with Serna, but wondered if anyone has tried this already.

Winpdb - A Platform Independent Python Debugger Embedded Debugging

1. Serna Enterprise source code will be available for the paid customers.
2. Serna core is written in C++. Some plugins are also written in C++, others - in Python.
