`create table … with pk` parsed column types as `name:type`,
while `add column` uses `name(type)`. Unify on the parens
form so column-type syntax is consistent across the DSL:
create table T with pk id(serial), name(text)
Only `COL_SPEC` changes (`:` → `( … )`); `build_create_table`
reads columns by role, so it is unaffected. The `:` that
separates table from column in `add column` / `drop column`
is unchanged. Sweeps the test suite, the typing-surface
matrix (two `after_colon` cells renamed to `after_paren`,
4 snapshots regenerated), the friendly catalog's usage
templates, ADR-0009's example, and requirements.md.
1039 passing / 0 failing / 1 ignored; clippy clean.
Implement ADR-0025 — indexes as a DSL DDL feature.
- Grammar: `add index [as <name>] on <T> (<cols>)`, `drop index
<name>` / `drop index on <T> (<cols>)`, plus a `--cascade`
flag on `drop column`.
- db.rs: index operations over the engine's native index
catalog (no metadata table). The rebuild-table primitive now
captures and recreates indexes, so `change column` and the
relationship operations no longer silently drop them.
- `drop column` refuses an indexed column unless `--cascade`,
which drops the covering indexes and reports each.
- Persistence: additive `indexes:` list in `project.yaml`
(version unchanged); round-trips through rebuild/export/import.
- Display: an `Indexes:` section in the structure view and a
nested tables/indexes items panel (S2).
Reconciles requirements.md (C3 index portion, S2 satisfied)
and CLAUDE.md. 1038 tests passing (+31), clippy clean.
Adds the explicit `rebuild` app-level command (ADR-0015 §7, §11)
and a modal UI infrastructure to host its confirmation dialog.
Typing `rebuild` emits Action::PrepareRebuild; the runtime reads
project.yaml + data/ to compute a summary ("3 tables and 47 rows
will be reconstructed; the existing playground.db will be
replaced") and posts AppEvent::RebuildPrepared, which opens the
modal. Y confirms, N/Esc cancels. While the modal is open,
normal input is gated.
The worker's do_rebuild_from_text now wipes existing user tables
and metadata before reloading from text, so it works on both
fresh and populated databases. Source text is plumbed through
rebuild_from_text so the explicit rebuild logs to history.log
while the silent on-load rebuild from Iteration 3 stays silent.
Modal infrastructure (App.modal field + key routing + centered
overlay rendering + word-wrap) is reused by Iteration 4b's save
/ save as / load / new flows.
Tests: 314 passing (268 lib + 9 + 5 + 6 new + 9 + 17),
0 failing, 0 skipped. Clippy clean.
When the runtime opens a project whose playground.db is missing,
it now rebuilds the database from project.yaml + data/<table>.csv
per ADR-0015 §7. The rebuild path:
1. Parses project.yaml (serde_yml). Unknown versions / types /
actions surface as PersistenceFatal.
2. Recreates each user table with FK constraints inline
(PRAGMA foreign_keys=OFF), then populates the column-type,
relationship, and project metadata tables.
3. Loads each table's CSV via a hand-rolled reader that
preserves the NULL-vs-empty distinction (the csv crate
doesn't expose whether a field was quoted; ours does).
4. Runs PRAGMA foreign_key_check before commit; any violation
aborts.
5. Restores foreign_keys=ON regardless of success.
Row-level failures get DbError::RebuildRowFailed with row
number, file, table, and a friendly per-type detail. They land
in the runtime as a fatal stderr message ("unable to load row N
from `data/T.csv` into table `T`: ...") before the alternate
screen is entered.
created_at from project.yaml overwrites the configure-time
placeholder so timestamps round-trip stably.
Tests: 307 passing (267 lib + 9 + 5 new + 9 + 17), 0 failing,
0 skipped. Clippy clean with nursery lints.
