# 260614 — Glamorous Toolkit (moldable development) deep dive
|
|
|
|

## What this is
|
|
|
|
A deep dive into **Glamorous Toolkit** (GT, on Pharo): **moldable development** — cheap,
|
|
custom, **domain-specific views** (`gtView` methods) so any object explains itself through an
|
|
**open set of co-equal projections, none canonical** — plus **Lepiter**, GT's live notebook/
|
|
knowledge base (git-versionable JSON page files with live, inspectable code results).
|
|
|
|
## Why it matters
|
|
|
|
- Strongest prior art for **moldable, multi-view projection**: projection is not *a* view
|
|
but an **open, type-keyed set of co-equal, possibly-computed views, none privileged** —
|
|
refines SHARD-WP-0002 **T16** and unifies replication-/derivation-/dimensional-/query-
|
|
projection under "many co-equal views."
|
|
- Generalizes ZigZag dimensional views (UC-47/48) and query/computed views (UC-54) into a
|
|
**pluggable view registry** keyed by content type (answers UC-55's open question on a
|
|
content-type registry).
|
|
- Reinforces **files-canonical, liveness-above, degrade-to-snapshot** (Lepiter files vs the
|
|
Pharo image; same boundary as Jupyter UC-84 / Squeak T6).
|
|
|
|
## Yield
|
|
|
|
- **No new UC** (design prior art, not a candidate shard — like the UseModWiki lineage dive).
|
|
- Enrich **UC-47, UC-48, UC-54**; links **UC-55, UC-83, UC-84, UC-79**.
