# About Krish Pandya
13+
14+
I'm Krish, aka MostlyK, a B.Tech student in Electronics and Communication Engineering at IIITH. While my degree might say ECE, I've completely fallen down the open source rabbit hole. I believe in doing things right the first time, even if it takes longer, and I approach problems by understanding the "why" behind changes, not just the "what."

18+
- Systems engineering and graphics programming
19+
- Open source development and contribution
20+
- C/Python development
21+
- Linux and System Adminstration

# Week 2: Strategic Pivot and Foundation Building
15+
16+
**Project:** [GTK4 Exploration](https://summerofcode.withgoogle.com/programs/2025/projects/rsHsYZKy)
17+
**Mentors:** [Walter Bender](https://github.com/walterbender), [Ibiam Chihurumnaya Ibiam](https://github.com/chimosky), [Juan Pablo Ugarte](https://github.com/xjuan)
18+
**Reporting Period:** June 06, 2025 till June 14, 2025

## The Meeting that changed everything
24+
25+
On Friday(06-06-2025), we had a pivotal video call with Juan Pablo Ugarte and Ibiam Chihurumnaya that completely reshaped the porting approach.
26+
What started as a discussion about my initial porting work evolved into something much more strategic and forward-thinking.
27+
28+
> While the time of writing this, another meet that happened on 13-06-2025 , we discussed about the API versioning and updating with pytest, ideas about testing, more porting golden advice, more about this on next week's blog.
29+
30+
### The New Architecture Vision
31+
32+
The mentors introduced a brilliant modular approach that addresses the core challenges of the GTK4 migration:
33+
34+
**1. Two Separate Libraries Strategy**
35+
- C Library 'sugar-ext': Core objects and reusable GTK widgets
36+
- Python Wrapper Library: Python widgets and wrapper functions
37+
38+
![GTK4 Planning](assets/Images/gtk4drawing.png)
39+
40+
> Subject to change
41+
42+
**2. Independent Development & Testing**
43+
Each library will be developed in its own repository with simple Python example scripts. This approach offers several advantages:
44+
- Clear separation of concerns between C and Python components
45+
- Easier debugging and testing
46+
- Better CI/CD pipeline management
47+
- Modular, incremental development that reduces complexity
48+
49+
**3. Meson Build System Foundation**
50+
We'll use Meson's shared library template from GNOME Builder as our base. This gives us:
51+
- Modern build system designed for GTK4
52+
- Better dependency management
53+
- Cleaner project structure
54+
55+
### Why This Approach Made Sense
56+
57+
The more I thought about this strategy, the more I realized how elegant it is. Instead of trying to port everything at once (my initial approach, by changing the orignal toolkit and it's systems), we're building a solid foundation that can support the entire Sugar ecosystem. This modular approach means:
58+
59+
- Maintainability — Each component can be updated independently
60+
- Testing — Smaller, focused libraries are easier to test thoroughly
61+
- Future-proofing — The architecture can adapt as GTK continues to evolve
62+
- Support — Due to the new build system, we would have more support and we can also remove things we find deprecated.
63+

64+
65+
## Implementation
66+
67+
Following the meeting – I immediately got to work implementing.
68+
The result that came out was [Pull Request #1](https://github.com/sugarlabs/sugar-ext/pull/1) in the new 'sugar-ext' repository.
69+
70+
### What I Built
71+
72+
**Project Structure:**
73+
- Complete Meson build system setup
74+
- GObject Introspection integration for seamless Python bindings
75+
- Initial API implementation (starting with XO Colors for testing)
76+
- Comprehensive documentation and development tools
77+
78+
**Key Technical Decisions:**
79+
```c
80+
// API versioning strategy
81+
api_version = '1.0' // Maintaining compatibility with existing SugarExt
82+
package_version = '0.122.0' // Following Sugar's versioning convention
83+
84+
// GIR configuration for Python bindings
85+
symbol_prefix: 'sugarext'
86+
identifier_prefix: 'SugarExt'
87+
```
88+
89+
> This was discussed later in the meet and we decided to keep the packages version 2.0 or 4.0 because GTK4. Will be confirmed by the next blog,
90+
91+
- Included comprehensive build and test scripts
92+
93+
### Testing Framework
94+
95+
The project includes a robust testing setup:
96+
```bash
97+
meson test -C builddir
98+
```
99+
100+
This runs the test suite, validating that the C library builds correctly and the test written should pass.

## Lessons from the PR Review Process
211+
212+
- To be added on week 3 as it gets merged!

214+
215+
# Migration List
216+
217+
- Here Use as-is means if we decide to keep it we use it or it's newer version or alternatives. Port meaning we would have to change stuff, and whenever I have mentioned GTK4 we will use the new API directly rather than implementing from scratch.
218+

257+
- Sugar-Grid was added on 14-June-2025 while I am writing this.
258+
259+
2. Begin Python Wrapper Development
260+
- Set up the Python-side repository
261+
- Create example scripts demonstrating usage
262+
263+
