v1.0.0 - Rewrite + Improved Performance

What's Changed

Summary:

• Simplified loader logic, moving cvars logic to templatetags
• Dropped internal requirement for component keys throughout
• Improved component template caching
• Cleaned shared responsibility of slot tag and created new internal tag - 'attr' to handle attribute expressions
• Simplified context handling, now keep all cotton related state in own context object
• Up to 32% faster*

Performance vs old*

These benchmarks were run over 5 iterations with 500 iterations per test case (representing the rare cases you may have ~500 components on the page), comparing Django native vs. Cotton for loops, block and extends, and includes.

For loop

Django average: 2.18 ms

- Cotton before: 4.65 ms
- Cotton after: 3.17 ms

✅ 31.83% improvement with the overhaul

---

Block and Extends (Django equivalent)

Django average: 9.38 ms

- Cotton before: 11.38 ms
- Cotton after: 10.56 ms

✅ 7.21% improvement with the overhaul

---

Include

Django average: 3.12 ms

- Cotton before: 3.16 ms
- Cotton after: 3.04 ms

✅ Cotton performs on-par with Django when used as partial inclusion.

⚠️ Possible breaking changes:

• Boolean attributes were previously triggered even when an attribute had an intentional empty srtring:

<c-comp myattr />
<c-comp myattr="" />
<c-comp :myattr="i_evaluate_as_empty_string" />

{{ myattr }} <!-- All cases above parse as True

This has now been fixed and only valueless attributes will render as True. Although this was unintentional, some of you may have relied on this defunct behaviour, so be sure to test.

• Support quoted json-like values in {{ attrs }} by @mattbha in #137
• updated render benchmarks by @wrabit in #138
• Support proper boolean attributes by @wrabit in #139
• Tags rewrite + optimisations (up to 28% faster) by @wrabit in
