Ideas List

This year we plan to apply to Google Summer of Code. Currently we are looking for project ideas. If you are a student, you are welcome to explore existing project ideas towards the GSoC application phase. There are ways to reach out to mentors, and many projects have lists of newcomer friendly issues you can start from. Students are also welcome to propose their own project ideas.

Propose Project

If you have a project idea, edit the “Project Ideas” section below by filling the required details and sending a pull request (this page is editable at, even if you could not mentor (we will find a mentor).

Projects Ideas

Move ETL library code to synfig-core

- Description

ETL is an Extended Template Library, like an extension of STL (Standard Template Library) For those who don’t know. Synfig began to be developed in the early 2000s, when there was no C++11, multithreaded programming, and other things that had already become part of the standard (std). The current task is to understand the logic of classes in ETL and replace them with an analogue from std, or if there are no analogs, transfer these classes as-is to synfig-core.

- Expected Results

From 3 packages (ETL, synfig-core, synfig-studio) 2 remains (synfig-core, synfig-studio)

- Difficulty Medium

- Skills required C++

- Mentor(s) Artem Konoplin (, Ankit Kumar Dwivedi (, Ayush Chamoli (

Replacement of deprecated Gtk classes

- Description

  • get rid of deprecated Gtk::StockId (since before 2013)

  • convert deprecated Gtk::Action to Gio::Action (since 2016)

  • convert/get rid of deprecated Gtk::UIManager to Gtk::Builder (since 2013)

  • (possibly) convert deprecated Gtk::Main 2 to Gtk::Application (since 2012)

- Expected Results

Let Synfig Studio code avoid unmantained code, as they can led to stability and security issues. Besides, it will ease porting of Synfig Studio to upcoming Gtk 4, that deletes all currently deprecated classes and methods.

Synfig compiles with the -DGDK_DISABLE_DEPRECATED -DGTK_DISABLE_DEPRECATED flags on Ubuntu 16.04 and Ubuntu 20.04

- Difficulty Easy

- Skills required* C++, Gtkmm

- Mentor(s) Rodolfo Ribeiro Gomes (, Ankit Kumar Dwivedi (

Performance enhancements

- Description

Improve the speed of Synfig export to files and rendering speed.

If you want to learn about how to find bottlenecks in an application, especially in a complicated one like Synfig, and fix them - select this project :)

This project is only for Linux (Linux has the necessary tools)

- Expected Results

Improved Synfig rendering speed, allowing users to work faster and create more complex animations.

- Difficulty Medium

- Skills required C++ (perf optional)
