`decimal` is stored as exact TEXT, but SQLite has no native decimal type,
so arithmetic/aggregation implicitly coerces it to an IEEE-754 double.
The computed result carries no playground type, so `sum(price * qty)`
rendered the double's full noise — `298.59999999999997` for `298.60` — a
confusing, off-topic float lesson for a teaching tool.
Add `format_real_display`: round REAL values to 15 significant figures
(a double's reliable precision) then take the shortest round-tripping
form, collapsing `298.59999999999997` to `298.6`. Wired into `format_cell`
(result-set / `show data` cells) only — the sole surface where the noise
appears, since it arises from arithmetic.
Every other f64->string path keeps full precision for semantic, not
cosmetic, reasons: CSV persistence stays byte-exact for round-trip;
`render_value` is a canonical identity key for the uniqueness dry-runs
(dry_run_unique, check_uniqueness_collisions), where rounding would
report collisions the exact-valued engine wouldn't; FK-key matching and
EXPLAIN-SQL literals likewise stay exact.
ADR-0005 Amendment 1; +7 tests.
A bare table alias typed where a column is expected — `… GROUP BY o`,
with `o` aliasing `FROM Orders o` — was a blind spot: completion offered
nothing for `o`, and the hint panel called the in-scope alias an unknown
column (`no such column o on table Orders, ...`).
Completion now offers each FROM source's qualifier (alias-if-present-else
table-name) at a bare sql_expr_ident slot, folded into the column
candidate list; on an exact-qualifier partial the alias source steps
aside so the diagnostic can surface. The bare-reference diagnostic arm
emits a targeted `alias_used_as_column` / `table_used_as_column` hint
("`o` is a table alias — write `o.<column>` ...") after the
projection-alias check, so ORDER-BY alias refs still win and a genuine
unknown column still reports `unknown_column`.
Two guards keep the qualified-form advice correct: SQL only (role
`sql_expr_ident`, so the DSL `expr_column` path keeps `unknown_column`
since the DSL has no `table.column` syntax) and effective-qualifier
match (alias-if-present-else-table, so an aliased source referenced by
its shadowed real name falls through rather than being advised as
`name.<column>`). The diagnostic is a drop-in replacement for
`unknown_column` at the same span/Error severity, so verdict/overlay/hint
paths are unchanged.
ADR-0032 Amendment 3; +10 tests.
The `:` one-shot escape (ADR-0003) is stripped at submission, but the
*live* feedback kept the leading `:` in the buffer it handed the
walker — so Tab completion, the validity verdict, and the highlight
overlays all bailed at the `:` and treated the SQL as an unknown
command. Effect: in `:`-mode, Tab completed nothing and a valid query
could flash an error, while the identical line in full `mode advanced`
worked. (The ambient hint already stripped it, which is why the hint
showed the right column name while Tab did nothing.)
Add `App::feedback_view()` — the `:`-stripped SQL view, the cursor
mapped into it, and the stripped byte offset — and route all four live
paths through it:
- completion (Tab): complete against the view, then shift the returned
`replaced_range` back by the offset so the edit lands in the buffer;
- validity verdict: verdict the SQL, not the sigil;
- highlight/overlays: new `render_input_runs_feedback` highlights and
diagnoses the view (shifted by the offset) while the `:` renders as
plain text;
- ambient hint: consolidated onto `feedback_view`, replacing the
duplicate local `strip_one_shot_prefix`.
In a SELECT, the projection can reference a table alias whose defining
FROM binding sits textually *after* the cursor — e.g.
`select sum(ol.count*p.price) … from … OrderLines ol …`. The candidate
engine already recovers that scope via the §10.6 full-input lookahead
(ADR-0032), but the typing-time validity indicator
(`invalid_ident_at_cursor`) walked only the text before the cursor,
found `ol` in no scope, and flagged it as an unknown column — a red
"ERR" overlay on an otherwise-valid query. (Other aliases escaped only
by coincidentally prefix-matching real columns.)
Give the validity check the same full-input lookahead: at a SQL
expression slot, recover the from-scope from the whole input and bail
when the partial prefix-matches a binding's alias or table name.
The partial-token walk stopped at `-`, so after typing `-` (or `--`)
the partial was empty and the replaced range was a zero-width point
*after* the dash. Two bugs followed at a flag position (e.g.
`add 1:n relationship … -`): the `on` keyword was offered (it
prefix-matched the empty partial), and accepting a candidate inserted
after the dash — `-on`, `---create-fk`, `----all-rows`.
Detect a dash-prefixed token at a word boundary as a flag-in-progress
and fold the whole dash-run into the partial, gated on a flag actually
being expected there (so `where x = -5` stays a signed number, not a
flag). The flag matcher now strips leading dashes and matches the body
uniformly (empty / `-` / `--` → all flags; `--cr` → create-fk).
Keywords like `on` no longer appear after a dash, and accept replaces
the dash(es) so `-` → `--create-fk` and `--all` → `--all-rows`. Two
partial-flag snapshots updated (they had captured the old behaviour).
Build the two SD2 surfaces Phase 1 deferred:
- `set` override clause (D2): comma-separated per-column pins —
`= 'v'` (fixed), `in ('a','b')` (pick-list), `as <generator>`
(named), `between x and y` (range; numeric and quoted dates).
Type-aware via the typed `current_column_value` slot; an override
drops its column from the generic-fill advisory (D13). Folded from
the flat matched path (build_seed_overrides) and applied to the
per-column plan (apply_seed_overrides).
- `<table>.<column>` column-fill (D1 form 2): an UPDATE over existing
rows. Refuses PK/autogen targets, empty-table no-op, FK-samples the
parent, collision-free for UNIQUE/identifier targets, one undo step;
`set` may only adjust the filled column.
Supporting work: KNOWN_GENERATORS vocabulary + generator_for_name
(src/seed/vocabulary.rs, D9); a range Generator + range_bounds_reason;
IdentSource::Generators and HighlightClass::Function; completion of the
generator vocabulary after `as` and the set/.col column slots; the
typing-time validity indicator for an unknown generator; help,
parse-error pedagogy rows, and the D13 advisory's Phase-2/3 wording.
A bounded override (fixed value / too-short pick-list) on a
single-column-UNIQUE target is a friendly error rather than a silent
uniqueness cap (post-implementation /runda finding, user-chosen).
Dates in the range form are quoted (no date-literal token exists);
ADR-0048 D2 amended accordingly. Both modes (D5); reproducible (D4).
P1.4 — user-visible surface:
- Grammar: `seed <table> [count] [--seed <n>]` (the first DSL flag with a
value); build_seed disambiguates the seed value from the positional count.
- Verified the auto-wired surface: table-name completion, --seed offered as
a candidate, validity consistent with `show data`, an ADR-0042 near-miss
row for bare `seed`, and render tests for the seed outcome.
/runda hardening — eight DA findings, all resolved:
- FK sampling now uses ORDER BY so --seed reproducibility no longer relies
on SQLite's unspecified DISTINCT order (D4).
- shortid columns now generate from seed's seeded RNG (new
shortid::generate_with_rng) — D4 now holds with no exceptions.
- Added the missing coverage the DA flagged: undo-one-step (D15), replay
re-runs a seed line (D16), advanced-mode (D5), atomic rollback on a
constraint failure, seed 0 no-op, complex-CHECK advisory (D17), and
FK + shortid reproducibility.
2358 pass / 0 fail / 0 skip, clippy all-targets clean.
do_seed inserted row-by-row through do_insert, re-writing the whole
table CSV each time — O(N^2). Extract do_insert's row core into a new
insert_one_row (bind + serial/shortid autofill + FK-enriched execute,
no tx/persist), shared by:
- do_insert: one row in its own transaction (behaviour unchanged).
- do_seed: all rows in ONE transaction, with a single
finalize_persistence before the single commit — O(N), preserving
ADR-0015 §6 commit-db-last. A mid-batch failure now rolls the whole
seed back atomically; the capped preview is read back by rowid.
A near-max 10000-row seed drops from ~tens of seconds to well under
one. do_insert behaviour unchanged (whole suite green: 2346 pass /
0 fail / 0 skip, clippy clean); seed's existing tests exercise the
batch path.
A dedicated SeedResult replaces the borrowed insert outcome (X5):
- CommandOutcome::Seed + DslSeedSucceeded event + handle_dsl_seed_success
render: the echo, "N row(s) seeded into T", a capped preview table
(D18, first 20 rows; full count always reported), and a Hint-styled
advisory naming enum-ish / un-derivable-CHECK columns filled with
generic text (D12/D13, Phase-1 wording).
- SeedResult carries requested vs produced, so a junction cap is now
reported to the user, not only logged.
- Count cap (D6): a seed over 10000 rows is refused with a friendly error.
- Catalog keys ok.rows_seeded / seed.capped / seed.advisory_generic.
4 new tests (advisory flag, IN-check not flagged, preview cap, excess
count). 2346 pass / 0 fail / 0 skip, clippy clean.
do_seed now enforces value uniqueness and derives enum values:
- Uniqueness groups (D10): the user-fillable PK, compound UNIQUE
constraints, and single-column UNIQUE / identifier columns stay
distinct across the batch and against existing rows (retry per row).
Junction distinct-combos fall out of PK-tuple uniqueness and cap at
the available parent combinations (logged when capped; the
user-facing note arrives with the advisory in P1.3c).
- Identifier-int columns get a monotonic sequence past MAX(col) (D10),
so they never collide.
- IN-CHECK derivation (D17): a simple `col IN ('a','b')` CHECK becomes
the value source via the new, unit-tested seed::parse_in_check_values,
so the enum-as-CHECK pattern just works.
8 parser unit tests + 4 integration tests (unique column, identifier
sequencing, junction cap, IN-check enum). 2343 pass / 0 fail / 0 skip,
clippy all-targets clean.
Deferred to P1.3c: dedicated SeedResult + capped preview (D18) + the
enum/CHECK advisory incl. the cap note (D12/D13); P1.3d: multi-row path.
do_seed fills foreign-key columns by sampling existing parent rows
(D14): sample_parent_key_tuples reads distinct parent keys, and a
compound FK reads all its child columns from one sampled parent row per
child row. An empty parent is refused with a friendly "seed the parent
first" error. The block guard (D1) refuses a NOT NULL blob column (seed
can't generate one); a nullable blob is omitted (-> NULL).
4 integration tests (valid FK references, empty-parent refusal, NOT NULL
blob refusal, nullable-blob omission). 2331 pass / 0 fail / 0 skip,
clippy all-targets clean.
Deferred to P1.3b: identifier/constraint uniqueness incl. junction
distinct-combos (D10), IN-CHECK derivation (D17), dedicated SeedResult +
capped preview (D18) + advisory (D12/D13), and the multi-row path.
The pure generation half of `seed` — no command wiring yet:
- src/seed/: ColumnSpec + Generator model and a seeded StdRng; the
type-gated name-heuristic catalogue (D7) with documented
false-positive guards; table-context name disambiguation (D11);
identifier (D10) and enum-ish (D12) detection; per-type + bounded-date
generators (D8); the hand-rolled product generator (D9); and PickFrom
for IN-CHECK / enum lists.
- Adds the `fake` crate (v5, default features). Verified: single rand
0.10.1 (no duplication), determinism via one seeded StdRng driving
both fake and the hand-rolled generators, security-clean across
osv/grype/trivy.
- ADR-0048 D3 updated to record the dependency verification.
32 Tier-1 tests (exact-value via fixed --seed); 1673 lib tests pass,
clippy all-targets clean.
Render the keystroke badge and step caption as a solid yellow rectangle
with no border glyphs and a one-cell text margin, instead of a
rounded-border box — deliberately unlike the app's bordered panels so
the demo overlays read as a distinct, eye-catching callout. Shared
fill_overlay_rect helper (borderless Block fill + inset Paragraph).
Snapshots regenerated; ADR-0047 D4 wording updated.
Ctrl+] (decodes to Char('5')+CONTROL) toggles an invisible capture
buffer: typed characters accumulate without touching the input/output,
Backspace edits, every other key is inert, and a second Ctrl+] commits
the text to a caption box (empty commit dismisses). Handled at the top
of handle_key — before the badge and modal gates — so captions can be
authored over the load picker (the #24 cast); an ordinary keystroke
clears a visible caption. The caption renders as a floating
black-on-yellow box at the output panel's bottom-right, wrapped to <=3
lines (then ellipsised), with the keystroke badge stacked directly
above it when both are present.
Tier 1: capture/commit, invisible accumulation, backspace, inert keys
(incl. no badge), empty-commit dismiss, next-key clear, over-modal,
demo-off inert. Tier 2: caption / stacked / wrapped snapshots. Phase C
of ADR-0047 — feature complete.
In --demo mode, an otherwise-invisible key (Tab, Enter, arrows,
Ctrl-O, …) raises a transient [LABEL] badge — a floating
black-on-yellow box inset at the output panel's bottom-right. Set in
App::update before the modal gate (so it shows over the load picker,
the #24 cast); pure demo_badge_label maps the key set. The runtime
expires it on a ~1.5s timer via a new nearest_deadline helper that
extends the existing time-boxed-recv arm condition without disturbing
the ADR-0027 indicator debounce. New App.last_output_area lets the
top-level draw anchor the overlay; overlay colours centralised in
theme.rs.
Tier 1 (label fn, badge set/seq, over-modal), Tier 2 (dark/light
snapshots, black-on-yellow style, too-small clamp), runtime unit
(nearest_deadline). Phase B of ADR-0047; captions land in C.
Add `--demo` (and the RDBMS_PLAYGROUND_DEMO env fallback) to enter
demonstration mode, threaded onto App.demo_mode through run_loop —
mirrors the --no-undo plumbing. Off by default, zero footprint when
off. The --help line advertises only the visible keystroke badges;
the Ctrl+] caption trigger is kept low-profile (ADR-0047 D6 updated).
Phase A of ADR-0047; behaviour (badges/captions) lands in B and C.
Add j (down), k (up), g (first) and G (last) to the load picker's
list sub-mode, alongside the existing arrow keys. Typeable keys keep
the picker drivable by autocast in the website's documentation casts,
which cannot emit arrow keys. Footer hint left unchanged.
DC3 — navigation-mode scroll: the focused Tables / Relationships panel
scrolls (Up/Down by a line, PageUp/PageDown by its visible-row count).
Per-panel offsets are clamped to content at render time, and the
renderer reports each panel's visible rows for paging — mirroring the
output panel's scroll. render_items_panel / render_relationships_panel
take &mut App, count their rows, and store+clamp the offset before
building the borrowing lines.
DC2 refinement: the expand-on-focus overlay now clears only the sidebar
strip plus a one-column gutter, leaving the base output/input/hint
visible (unchanged) to the right rather than blanking the whole area —
truer to "underneath keeps its layout", with the gutter keeping the
cut-off edge clean (chosen after eyeballing both variants). ADR DC2 and
the overlay snapshot updated to match.
Tests: line/page scroll move only the focused panel and clamp; the
render clamps a past-the-end offset so the last row stays visible.
Ctrl-O enters a navigation mode orthogonal to the input mode, cycling
focus Input -> Tables -> Relationships -> Input (Esc exits). While a
sidebar panel is focused the sidebar is revealed (a peek, even when
width-hidden) and drawn as an expanded 45-column overlay over a cleared
main area, so the schema is browsable without the cramped 26-column
unfocused width. The focused panel gets an accent border.
Routing lives in the main key handler after the modal gate, so Ctrl-O
and nav keys are inert while a modal is open; in nav mode every
non-navigation key (printable/Enter/Tab/Backspace/...) is inert because
the input is occluded. Scroll keys (Up/Down, PageUp/PageDown) are
reserved for DC3 (next).
New App state: NavFocus { Input, SidebarTables, SidebarRelationships }.
Tests: the focus cycle, Esc exit, input-keys-inert, overlay reveal +
expansion, the accent-border style, and an overlay snapshot.
The left column now stacks a Tables panel over a Relationships panel.
Each relationship renders as three narrow lines — its name, then the
endpoints broken at the arrow (Customers.id -> / indented
Orders.customer_id) — ellipsized past the inner width. The panel is
content-sized within [5 rows ("(none)" when empty), half the column];
the Tables panel keeps the rest (>=3 rows). Phase C adds focus+scroll
for content beyond the cap (clipped for now).
Data path: a new worker Request::ReadAllRelationships +
Database::read_all_relationships returns full RelationshipSchema
records; the runtime posts them via a RelationshipsRefreshed event
alongside the schema-cache refresh, and the App holds them in a new
`relationships` field.
ADR deviation (recorded in ADR-0046 DB2 + index): DB2 specified this
data on SchemaCache; it lives on the App instead — SchemaCache is
walker/completion-facing and needs only relationship names (untouched),
while the full records are UI-only, so App is the cleaner home and it
avoids editing ~23 SchemaCache literals. No behavioural difference.
Tests: panel-height bounds, the three-line render, the empty "(none)"
case, a snapshot, read_all_relationships end-to-end (real DB via the
m:n junction), and the event->field handler.
The schema sidebar (the left Tables column) is now shown only when the
terminal is wider than 90 columns; at or below that it is hidden and
the output/input panels span the full width. This reclaims horizontal
space on narrow terminals — notably the 90-column screencasts, where
the sidebar added little and cost the output panel its width.
Visibility is a pure function of terminal width (sidebar_visible);
the Ctrl-O peek-reveal lands in Phase C. render() splits the layout
conditionally — full-width right column when the sidebar is hidden.
Snapshots/tests that rendered at 80 wide now reflect the hidden
sidebar; those whose intent IS the sidebar (populated_with_table, the
items-panel and drop-table integration checks) render at 110 so the
Tables list is actually exercised — one masked-intent integration
check (matched "Customers" in the output, not the panel) is corrected
the same way. New tests cover the width gate and the show/hide
boundary.
On a comfortable terminal (height >= 40) the input panel shows two
rows: the single logical command soft-wraps across them — the first
row stops 6 columns short for the ADR-0027 validity indicator, the
second uses the full width — so a medium command is fully visible
without horizontal scrolling. A line longer than both rows still
scrolls (DA3-style, one column each side reserved for < / > markers)
to keep the cursor visible.
hint_rows generalises to panel_heights(area) -> (input_rows, hint_rows):
compact (<40) stays input 1 / hint 2; comfortable becomes input 2,
degrading hint-then-input on tiny terminals to protect the output
Min(5). render_input_panel splits into render_input_one_row (the
existing DA3 path, unchanged) and render_input_two_rows, with a new
expand_runs_to_cells helper placing styled cells across the rows.
Tests: panel_heights geometry, two-row wrap, overflow-scroll, the
indicator-stays-on-the-first-row case, and a two-row layout snapshot.
Compact one-row snapshots are byte-identical (that path is untouched).
A command longer than the input field used to clip silently at the
right edge, hiding the cursor and the command tail. Now the single
logical input line scrolls horizontally to keep the cursor in view,
with muted `<` / `>` markers at the reserved edge columns signalling
hidden content on either side.
The offset is a pure function of (line length, cursor column, field
width, previous offset) — input_scroll_offset — so the view only moves
when the cursor would leave the window, and one column is held on each
side for the markers so a marker never hides the cursor. The stored
App::input_scroll_offset resets when the buffer is replaced wholesale
(submit, history recall). The ADR-0027 6-column indicator reserve is
preserved.
Tests: pure-offset cases, tail-visible + head-visible render checks,
and the reset-on-submit/history check. One layout snapshot now shows a
long command's tail instead of its clipped head.
The hint panel's height was recomputed every frame from the wrapped
hint content (1–3 rows), so it resized as the user typed and shoved
the input/output panels — the flicker visible in the screencasts.
Make the height a pure function of terminal geometry (new hint_rows),
fixed between resizes: 2 content rows on compact (<40-row) terminals,
3 only on comfortable terminals narrow enough (<54 inner cols) to wrap
the longest catalog hint past two lines, degrading toward 1 on tiny
terminals to protect the output Min(5). resolve_hint_lines clamps to
that fixed budget (long hints ellipsize; short ones leave rows blank).
This reverses issue #12's shrink-to-content "reclaim"; its two tests
are replaced by an anti-jump invariant plus geometry-helper and
third-row tests. Two layout snapshots regenerated.
`create m:n relationship from <T1> to <T2> [as <name>]` generates a
junction table with one FK column per parent PK column ({table}_{pkcol},
typed via fk_target_type), a compound PK over them, and two CASCADE 1:n
relationships -- all in one do_create_table call = one undo step.
Auto-named {T1}_{T2} (optional `as`), both modes, compound-parent PKs
supported (ADR-0043). Self-referential m:n / PK-less parent / internal
junction name / name collision all refused.
Wired across every surface: grammar (separate CREATE_M2N node), worker
executor, runtime dispatch, completion ("m:n" composite), hints,
highlighting, help + usage catalog + disambiguator, and the advanced-mode
DSL->SQL teaching echo (render_create_m2n, round-trips as valid SQL).
Generalized/fixed framework assumptions the build + two /runda passes
surfaced (all behaviour-preserving for existing commands):
- simple-mode dispatch committed simple.first() unconditionally -> tries
candidates, so `create table` no longer shadows `create m:n`.
- the completion continuation-merge was advanced-only -> runs in simple
mode too when an entry word has >1 DSL form (gated simple_count>1).
- do_create_table now rejects internal `__rdbms_*` names (closes a
pre-existing hole on the DSL create-table path too, not just m:n).
- usage disambiguator now recognizes the `m:n` opener.
Tests: 14 integration (tests/it/m2n.rs), 7 typing-surface matrix, echo /
highlight / usage / internal-name units. Closes C4.
2237 pass / 0 fail / 1 ignored. Clippy clean.
ADR-0043 residual: a compound-FK violation's friendly error named only the
first child->parent column pair (the ADR-0019 facts model is single-column).
enrich_fk_violation now gathers all pairs of the matched relationship and
carries them comma-joined in the existing single-column facts slots, so the
headline reads e.g. "no parent row in `Region` has `country, code` = `7, 8`."
instead of naming just `country`.
Single-column behaviour is unchanged (a one-element join is the element
itself). No facts-model or catalog change -- the joined strings flow through
the existing `{parent_column}` / `{value}` placeholders.
Tests: enrichment facts (compound names every pair, single-column
regression) + translate rendering (headline names both columns). 2211 pass
/ 0 fail / 1 ignored. Clippy clean.
ADR-0043 D4 residual: an inline column-level FK (`<col> REFERENCES P(a,b)`)
is single-column by construction, so referencing a parent's compound PK
gave the generic arity error ("1 foreign-key column(s) on the child side,
but `P`'s key has 2..."). It now points the user at the table-level form:
"an inline column reference can only name one column ... Use the table-level
form instead: FOREIGN KEY (<columns>) REFERENCES P (a, b)".
- Adds `inline: bool` to SqlForeignKey, set by the grammar's single shared
builder consume_fk_reference (true for the inline path, false for the
table-level and ALTER paths).
- resolve_fk_parent_columns takes `inline` and tailors the arity-mismatch
message when an inline FK meets a compound key.
Tests: parse-layer (inline=true / table-level=false) + end-to-end worker
refusal wording. 2209 pass / 0 fail / 1 ignored. Clippy clean.
Completes the X1 full sweep started in a8ad0c6 (db.rs). Closes X1 -> [x].
- persistence/mod.rs: debug! on every yaml/CSV/history write -- the
silent-failure-prone disk paths (write_schema, write_table_data incl.
the empty->delete branch, append_history/_failure).
- runtime.rs: debug! on execute_command_typed dispatch (one per executed
command, complements the db.rs executor logs).
- app.rs: debug! on submit (route + submission mode), dispatch_app_command,
and the ADR-0044 diagram-vs-prose render-mode choice.
- dsl/parser.rs: trace! on parse begin/outcome at the parse_command_inner
choke point -- trace, not debug, because the live overlay/completion
re-parse per keystroke (hot path).
- logging.rs: documented level discipline (error/warn/info/debug/trace) so
the convention survives across sessions.
Levels verified end-to-end through the real worker thread + logging::init.
~75 -> 135 tracing sites total. Tests: 2207 pass / 0 fail / 1 ignored.
Clippy clean.
Instrument db.rs to the CLAUDE.md "log liberally" bar (X1). 26 -> 67
tracing sites:
- Entry-level debug! on all 34 do_* executors (DDL, DML, relationship,
index, read paths), matching the existing do_sql_delete/do_run_select
style -- so the route through delegating executors (e.g. add_column ->
add_constrained_column_via_rebuild) is visible in the log sequence.
- Decision-point logs: rebuild_table primitive (begin/commit; FK-check
failure and foreign_keys re-enable failure as warn), do_insert autofill
summary, do_delete cascade summary, do_create_table FK resolution.
- Worker lifecycle (start/exit) raised debug! -> info! so it shows at the
default level.
Levels per the X1 discipline: debug for per-command detail (off by
default, opt-in via RDBMS_PLAYGROUND_LOG=debug), info for lifecycle, warn
for fallbacks. Loops log summary counts, never per-row.
Tests: 2207 pass / 0 fail / 1 ignored (unchanged). Clippy clean.
Completes requirement V1. A compound (multi-column) FK now routes a
bus connector — each paired endpoint's stub merges into a shared
vertical channel that splits to the other side — plus an explicit
"(a, b) ▶ P.(x, y)" pairing line; the bus generalises the single-column
jog (reproducing it exactly, so prior snapshots are unchanged).
Self-referential FKs render as two same-named boxes.
- output_render.rs: gutter_seg routes all endpoint pairs via a
junction() bus; pairing line for compound FKs; compound, self-ref,
and compound-from-data (build_diagram_table glue) tests + snapshots
- compound_fk.rs: worker test that show_relationship carries both
paired column lists into the diagram payload
- db.rs: document do_show_one's now-app-superseded relationship prose
branch (retained as a worker-API/text fallback; could back a future
non-visual display option, cf. ADR-0044 OOS-7)
Second /runda pass over the implementation: confirmed ADR-compliance,
UTF-8/byte-range safety, and edge-case routing. The ADR §3 last-resort
helper line was considered and rejected (vertical fallback + ratatui
truncation cover all realistic cases). ADR-0044 marked implemented;
requirements.md V1 -> [x].
Full suite 2207 pass / 0 fail / 1 ignored; clippy nursery clean.
show table <T> and add/drop relationship echoes now render the focal
structure box plus a Relationships section of compact stacked
connector diagrams (child-left/parent-right, n…1, actions); incidental
DDL echoes keep the prose References:/Referenced by: form. Selected by
command in handle_dsl_success via the "relationship-relevant" reach.
- output_render.rs: render_structure refactored into section helpers
(box/prose/index/constraint), byte-identical output; new
render_structure_with_diagrams + compact-box rendering
- app.rs: handle_dsl_success routes ShowTable/Add/DropRelationship to
the diagram path, others to prose
- fixes: eager widths[1] index on compact (1-col) boxes; body-cell
padding under title-widening (name wider than columns)
Tests: unit + snapshot + integration; add-relationship echo test
updated to the diagram form. Full suite 2203 pass / 0 fail / 1 ignored;
clippy clean. V1 still [/] (compound routing + self-ref remain).
The first wired slice of relationship visualization (V1). `show
relationship <name>` now renders the relationship as two full
structure boxes joined by a width-jogging connector (child-left /
parent-right, n…1 cardinality, on delete/update actions), styled
App-side, with a vertical-stack fallback for narrow terminals.
- db.rs: RelationshipDiagramData + show_relationship worker path
(structured data: the relationship + both endpoint TableDescriptions)
- runtime.rs: named relationships route to the structured outcome
(boxed); other show <kind> forms stay prose
- app.rs/event.rs/ui.rs: DslShowRelationshipSucceeded rendered App-side;
new diagram OutputStyleClass variants; App::last_output_width from ui.rs
- output_render.rs: styled Seg layout engine (boxes, connector routing,
side-by-side + vertical), composing the ADR-0016 box primitives
Tests: 4 unit + 4 integration; full suite 2201 pass / 0 fail / 1 ignored;
clippy nursery clean. requirements.md V1 stays [/] (show table diagrams,
compound routing, DDL-echo wiring remain).
Multi-column FK parsing on both surfaces: DSL from P.(a, b) to
C.(x, y) (parenthesized endpoint; single bare form unchanged) and
SQL FOREIGN KEY (a, b) REFERENCES P(x, y) incl. bare-reference
auto-expand. consume_fk_reference + the table-level/ALTER FK
parsers collect column lists; the from P. completion now offers
( (snapshots updated). 12 integration tests in
tests/it/compound_fk.rs cover parse (both surfaces), engine-enforced
FK, arity + partial-PK + per-pair-type-mismatch refusal,
--create-fk per-column, save->rebuild round-trip, undo (one step),
and single-column preservation. Mark T3 [x]; ADR-0043 implemented.
Fold the singular per-item forms into Command::ShowList { kind,
name: Option<String> } (name: Some = one item). Two grammar
branches reuse the relationship/index completion sources; worker
do_show_one renders a labelled detail block or a friendly
"No ... named X." line, reusing the V5 render path. Help +
parse-usage entries, two ADR-0042 near-miss rows, 5 integration
tests. Mark V5a [x] — V5's [<name>] clause now complete.
HELP node takes an optional single-word topic (BarePath);
AppCommand::Help { topic }. note_help_topic renders the help
block(s) of every command sharing that entry word (so `help
create` covers both create forms), plus `help types` and a
friendly "no help for X" pointer for unknown topics. Full help
gains a detail-hint footer. Catalogued help.detail_hint /
help.unknown_topic; parse-error matrix updated (help now takes a
topic, so the near-miss is the multi-word case). 9 integration
tests in tests/it/help_command.rs. Mark H3 [x].
Add the list-all show family as one Command::ShowList { kind }
variant. A read-only worker show_list formats count-headed lists
(reusing do_list_tables / read_all_relationships /
read_table_indexes, so it never drifts from the items panel);
internal __rdbms_* tables excluded. Help + parse-usage entries
added; 10 integration tests in tests/it/show_list.rs.
Mark V5 [x]. Split the singular show relationship/index <name>
detail forms (the [<name>] half) into a new tracked V5a [ ] item
rather than leaving them as an untracked footnote.
Empirically re-checking ADR §3's advanced-SQL "gaps" reversed two of
three — the code survey that produced the list was wrong:
- INSERT…SELECT column-count: already handled (verdict=Error, "the
column list names N column(s) but M value(s) are given";
insert_select_arity_mismatch_fires).
- RETURNING scope: already handled (completion offers the table's
columns; `returning <unknown>` → unknown_column diagnostic).
The one genuine residual is fixed: `select … cross join b on …`
rejected the ON with a bare "expected end of input". Add
parse.cross_join_no_on — "a CROSS JOIN has no ON clause — it pairs
every row; for a join condition use `JOIN … ON`, or filter with
`WHERE`" — rendered when the failing token is `on` and the most
recent consumed join is a CROSS join (a precise signature: every
other join requires `on`, so `on` is expected there, not a failure).
Render-only in format_walker_error; two misfire guards locked (plain
join still asks for ON; a stray `on` with no join does not fire).
ADR-0042 §3 corrected + Implementation-outcome records the advanced-SQL
re-check and the user-confirmed low-priority residual (submit-time
expression first-set at non-projection positions, where typing-time
completion already offers the right candidates).
Full suite green (lib 1578 / it 388 / typing_surface_matrix 192); clippy clean.
The /runda DA pass found G3 over-corrected: advanced-mode `create`/`drop`
showed SQL forms only, hiding the DSL fallback forms that are valid input
in advanced mode (verified: `create table Foo with pk`, `drop column …`
parse and dispatch). Per the user decision, the advanced usage block now
shows every form valid in the mode, SQL-primary first, then the DSL
fallback forms — a usage hint must never hide working input. Simple mode
unchanged (DSL forms only).
Matrix completion (closing the residual coverage tail):
- arg-less app commands (help/rebuild/new/load/undo/redo/export/import)
audited + locked — all reject trailing junk with "expected end of
input" + usage.
- committed multi-forms (add index/constraint/1:n relationship, drop
index/constraint/relationship, show table, change column, create index,
alter table add/drop) audited + locked in
near_miss_matrix_committed_multiforms — each renders its own
form-specific missing-keyword message + usage.
Also from the DA pass:
- G2 distinct+all detector empirically verified unique to projection
start (no misfire at count( / union / union all / select distinct).
- stale `chumsky` comment removed (app.rs import handler).
- ADR-0042 Implementation-outcome section records G1–G4, the
user-confirmed G3 decision, and the now-complete matrix coverage.
Full suite green (lib 1578 / it 387 / typing_surface_matrix 192); clippy clean.
Close the three remaining ADR-0042 triage gaps, each test-first, and
lock the advanced-mode near-miss matrix.
G2 — bare `select` dumped the 14-item expression first-set. Collapse
it to "a projection: `*`, a column, or an expression" in the error
message only (parser::format_walker_error), detected by the joint
`distinct`+`all` quantifier signature unique to a projection start.
Render-only: completion/hints still expand the full set (typing-surface
matrix unchanged).
G3 — the usage block was mode-blind: advanced `create table` showed the
DSL `create table … with pk …` template. usage_key(s)_for_input gain
mode-aware `_in_mode` variants selecting candidates by CommandCategory;
render_usage_block and the typing-time ambient usage thread the
submission mode. Advanced `create` now shows both SQL forms. A fallback
covers shared SQL nodes (insert/update/delete) that declare no
usage_ids of their own — without it they regressed to the
available-commands fallback (caught by the new advanced matrix).
G4 — `with` borrowed `select`'s usage template; give it its own
parse.usage.with CTE template.
Tests: new near_miss_matrix_advanced_mode (12 SQL-surface cases incl.
the available-commands regression guard) + per-gap tests; removed the
temporary baseline_dump. Full suite green (lib 1578 / it 386 /
typing_surface_matrix 192); clippy clean.
Start the ADR-0042 §1 near-miss matrix: a table-driven
near_miss_matrix_simple_mode locking 26 simple-mode parse-error
renderings (every DSL entry word's bare/missing-clause cases plus the
mode arg-errors and the "this is SQL" rail), and an #[ignore]
baseline_dump capturing the full rendering for ongoing triage.
G1 fix: the bare `1` cardinality literal that opens `add 1:n
relationship …` rendered cryptically in expected-sets. Render it as
`1:n relationship` in error wording only (format_expectation) —
completion/hints still read the raw Expectation::Literal("1"), so the
candidate surface is unchanged. Updated the one anchor test.
Full suite green (lib 1578 / it 382 / typing_surface_matrix 192).
Verification found H1 (ADR-0019) fully implemented and tested: the
friendly::translate_error chokepoint is wired on the live failure path
(runtime + app + DbError::friendly_message), covers all five error
categories (UNIQUE, FOREIGN KEY both sides, NOT NULL, CHECK,
type-mismatch) with operation×kind×verbosity wording, the messages
verbosity command, and §6 row-pinpointing via runtime-resolved facts —
backed by 44 friendly unit tests + 12 full-stack friendly_enrichment
integration tests. The "partial / FK-only" notes were stale.
Mark requirements H1 done; fix the obsolete "diagnostic_table is
always None" comment in translate.rs (pinpointing landed in 431645a).
Remaining ADR-0019 scope (§9 i18n sweep, §OOS-2 advanced-SQL
sanitization, §OOS-3 messages persistence) stays deferred.
serde_yml (RUSTSEC-2025-0068) and its libyml backend
(RUSTSEC-2025-0067) are archived, unsound, and unmaintained with no
patched version. Swap to serde_norway, the maintained serde_yaml fork
on unsafe-libyaml-norway — a drop-in for our from_str / to_string /
Value usage across persistence, undo, and the catalog parser.
Clears both advisories (cargo audit / osv-scanner / grype all clean;
serde_yml + libyml gone from the tree). No behaviour change; full
suite 2151/0/1.
New app-level `copy` / `copy all` / `copy last` command (ADR-0041).
Delivery is OSC 52 *and* a best-effort native write (arboard), always
both — OSC 52 acceptance is undetectable, so a true fallback can't be
built. Payload is the panel's plain text exactly as rendered (tags,
✓/✗, box-drawing), drift-locked to render_output_line. arboard added
--no-default-features (X11-only; OSC 52 covers Wayland).
Amends ADR-0003's command registry; requirements V6.
The post-/runda DA pass on 4cd574b found the persist-on-unload wiring
(quit + project switch calling Database::set_mode) had no integration
test — only the db-level set_mode behaviour was covered, not that the
runtime actually invokes it on unload.
Add runtime::switch_persists_the_outgoing_projects_mode, driving the
real handle_project_switch end-to-end and asserting the outgoing
project's project.yaml recorded the mode it was left in. Red-first
verified: with the set_mode call disabled it fails (None vs
Some(Advanced)). The quit unload site shares the same set_mode call;
Action::Quit emission is already covered in app tests.
Updates ADR-0015 Amendment 1 coverage note.
The input mode always started in simple; a learner who quit in advanced
had to re-toggle every launch. Store the mode per-project in project.yaml
(project.mode:, optional, default simple) and restore it on every open.
Mode is live UI state, not schema: the worker stamps the current mode
into project.yaml on every write, so a later command rewrites the live
value rather than clobbering it — no db round-trip needed. The mode is
persisted on unload (quit + project switch) so the mode you leave a
project in is always what reopens; the `mode` command also persists
immediately. A switch saves the outgoing mode, then restores the
incoming project's stored mode.
New --mode simple|advanced CLI flag (precedence --mode > stored >
simple; combines with --resume). A teacher can ship a project that
opens in advanced mode and export it to students (the mode travels in
the zip).
ADR-0015 Amendment 1; ADR-0003 note; help banner; requirements L1b.
The output tag was tinted by submission mode for every line kind, so a
[system] line and an [error] line rendered with an identical leftmost
tag — distinguishable only by body colour. And flooding the whole error
body in red made long messages hard to read.
Colour the tag by message status instead (its OutputKind): [system] →
green, [error] → red; the echo tag keeps the mode tint (ADR-0037's
actual purpose — per-command success rides the ✓/✗ marker). Bodies go
neutral; the error body stays bold for weight (rustc-style: severity-
coloured label, readable bold message). Yields a status traffic-light
matching the ✓/✗ palette.
Narrows ADR-0037's mode side-channel to the echo line it was always for.
ADR-0037 Amendment 1; closes the tag-colour gap ADR-0040 flagged as OOS.
Add src/dsl/sql_functions.rs (KNOWN_SQL_FUNCTIONS) as the shared source
of truth at sql_expr_ident slots:
- #15: offer the functions as Tab candidates under a new
CandidateKind::Function + ninth Theme colour tok_function (blue,
distinct from keyword/identifier/type).
- #16: restore the column-typo flag the #6 fix had dropped wholesale —
invalid_ident_at_cursor now bails only when the partial prefix-matches
a known function, else falls through to the schema-column check.
A column named like a function (e.g. `count`) is deduped (column wins).
`cast` is excluded — CAST(x AS type) is not a plain-call shape.
The no-validation-allowlist posture stands: the list drives completion +
the typo hint only, never parse-time acceptance.
Docs: ADR-0022 Amendment 6, ADR-0031 status note, README index,
requirements I3/I4 + refreshed test baseline.
An audit of the command surface found the `[ok] <verb> <subject>`
summary line duplicated the echo line above it everywhere; its only
unique signal was success-vs-error. Retire it: a command's echo line
now resolves from `running: <input>` to `<input> ✓` / `<input> ✗`
on completion, and the symmetric `"<verb> <subject>" failed:` prefix
is dropped (only the reason remains). Content lines (row counts,
structure, plan tree, teaching echo) are unchanged.
Echo lines carry an EchoStatus; executed commands push Pending and
resolve the oldest-pending echo on their result event (FIFO worker —
correct under interleaving). Parse-time and pre-flight rejections are
not executed and keep their running: + caret rendering. App-command
[ok] lines (rebuild/export/replay) are payload-bearing and untouched.
ADR-0040.
