feat(query,viewer): read IfcOpenShell selector syntax in the Filter tab - #4106
Merged
Conversation
The viewer, the CLI and the SDK each take a different structured filter and none reads the selector syntax the IfcOpenShell docs describe, so every example from that page matched nothing and reported nothing (#4091). A trailing `*` made it worse: `IfcWall` found 15 elements in the running viewer and `IfcWall*` found 0, because the star was matched as a literal character. Add `parseSelector` to `@ifc-lite/query`: a tokenizer plus a recursive-descent parser over the full grammar, returning either an AST or an error with the offset that broke. The parser deliberately accepts more than any one surface can evaluate — `type=`, `parent=`, `query:`, `+` unions — so an adapter can name what it dropped instead of silently matching nothing. Tests pin one case per worked example on the docs page, asserting the exact AST, plus quoting, escapes, regex literals, NULL, operator precedence and the error offsets.

The rule model had no way to say "matches this pattern": the Name rule offered
eq / ne / contains / notContains / startsWith, and a property rule compared set
and property names by lowercase equality. So the selector syntax's two regex
forms, `Name=/D[0-9]{2}/` and `/Pset_.*Common/.FireRating`, had nothing to land
on (#4091).
Add `matches` / `notMatches` to StringOp, ValueOp and ClassificationOp, and
route the property and quantity name compare through `nameMatches`, which reads
a `/…/` literal as a regular expression and anything else as the equality it
was. Both reuse `compileNameMatcher` from `@ifc-lite/lists`, so the cache and
the `g`/`y` flag strip that keep `.test()` from alternating are already there.
Regex matching is case-SENSITIVE, unlike every other op here, because the
grammar's `/…/` is a Python regular expression. An invalid or empty pattern
matches nothing rather than throwing. `isFilterRule` keys on `kind` alone, so
saved presets carrying a regex op round-trip unchanged.

The IfcOpenShell page says `location="Level 3"` matches an element contained directly OR indirectly in a spatial element of that name, and its example 17 is a pump sitting in a space on Level 3. ifc-lite's storey rule reads `spatialHierarchy.elementToStorey`, which is built from direct containment plus aggregated parts, so whether it answers example 17 is a question about the parser, not about the rule. Measure it against a real parse rather than reasoning about it: a pump inside a space, a wall directly in the storey, one `Rule.storey(['Level 3'])`. The storey rule matches the wall and does NOT reach the pump; the space itself does map to its storey. That result is what the docs matrix will say, and it is the case a spatial-ancestor rule has to change (#4094).

`selectorToFilterRules` turns the selector AST into `FilterRule[]`: class filters fold into one expanded `ifcType in` rule (and one `notIn` for the `!` subtractions), Name and PredefinedType become their attribute rules, a `Pset.Prop op value` becomes a property rule with `= NULL` / `!= NULL` reading as isNotSet / isSet, a `Qto_`-prefixed set with a numeric value becomes a quantity rule, and material, classification and location become theirs. The class expansion is the part that changes answers: `IfcWall` now reaches `IfcWallStandardCase`, which is why a model full of them stopped answering zero, and `IfcElement` reaches its whole branch. Everything the rule model has no home for — GlobalId terms, `type=`, `parent=`, `query:`, attributes other than Name and PredefinedType, `+` unions, an operator a dimension cannot take, a regex JavaScript cannot compile — comes back in `unsupported`, quoting the text as typed. That list is the point: a construct that produced no rule and no complaint is #4091 exactly. Mutation-checked: deleting the `expandTypes` call fails 16 cases including IfcWall -> IfcWallStandardCase; dropping the GlobalId report fails 4 including example 5.

The Filter tab is a chip builder with no text entry, so someone arriving with the IfcOpenShell syntax in hand had nowhere to put it and fell back to the search bar, which matches the characters literally (#4091). Add a selector field above the rule list. Apply parses, adapts, and replaces the rules; a parse error applies nothing and points at the character that broke it; a construct with no rule is named rather than dropped. `IfcWall*` now says that `*` is only part of `*=` instead of returning zero elements. "Add <query> as rule" reads the search bar as a selector when the whole thing maps cleanly, and keeps `Name contains` otherwise, including when part of the selector is unsupported — falling back is honest, a partial reading is not. Mutation-checked: replacing the Apply handler with a no-op fails 5 of the 7 UI cases.

`@ifc-lite/query` gains `parseSelector` and the AST types, which is a minor bump and a snapshot refresh. Narrow what leaves the package while doing it: the six per-kind filter interfaces and `SelectorKeywordKind` stay module-internal, since a caller narrows on `filter.kind` off the union rather than naming each member, and an export with no consumer is permanent semver liability. `TokenKind` was exported by nothing and is now local to the lexer. The viewer's selector field takes `SelectorParseError` instead of restating its shape.

The gap #4091 reported was as much a documentation gap as a code one: nothing said which parts of the IfcOpenShell selector syntax ifc-lite reads, so a selector that matched nothing looked like a mistake by the person who typed it. Add `docs/guide/selector-syntax.md`: the grammar as ifc-lite reads it, a per-construct support table for the viewer's Filter tab, and a mapping table for the CLI, MCP and SDK filters, which are structured rather than textual and stay that way for now (#4094). Two entries are measured rather than assumed. `location=` reaches an element a storey contains directly and not one nested inside a space on that storey, per the test in `filter-evaluate.test.ts`, so IfcOpenShell's pump example does not carry over. And the clash selectors' `IfcDuct*|IfcPipe*` glob is named as the separate older mini-language it is, since the viewer rejecting `IfcWall*` while the CLI advertises it is otherwise just confusing.

`knip` flagged the six per-kind filter interfaces as exported types nothing consumes: trimming them out of the package index left them still `export`ed from `ast.ts` and reachable from nowhere. Drop the keyword. The emitted `.d.ts` still carries them as the union's constituents, so `SelectorFilter` narrows on `filter.kind` exactly as before, and the API surface snapshot is unchanged.

`Pset_BeamCommon."IsExternal" = FALSE` was a parse error while `/Pset_.*Common/."IsExternal" = TRUE` parsed. The lexer keeps a '.' inside a bare word on purpose, so a decimal value like `1.5` stays one token; the consequence was that a literal property set never reached the dot branch and its quoted property name was read as a stray token. Only the regex spelling worked, one character from the selector the reporter typed. parseFilter now takes a word ending in '.' followed by a quoted or regex token as the property-set/property pair. The decimal case is unchanged and still pinned by its own test.

The adapter re-encoded the AST's discriminator into a `/…/` spelling and the matchers guessed it back out of the text. Both directions of that guess are wrong, and both matched the wrong elements without saying anything, which is the defect #4091 reported reappearing one layer along: "/Wall/".FireRating=2HR quoting is the grammar's only escape hatch for a literal name, and the rule read it as a pattern that swallows Pset_WallCommon. Name=/\/tmp\// the source IS `/tmp/`; sniffed for delimiters it compiled to `tmp`. Rules now carry a `TextKind` per string: 'regex' is a source compiled whole, 'literal' is text that is never a pattern, and an absent kind is free text a human typed into a chip field, where the Lists-panel `/…/` convention (#1591) is the only way to say "pattern" and reading it is the grammar rather than a guess. The chip editors clear the kind on the field they edit. Splits the pure operator matchers out of filter-rules.ts into filter-ops.ts at the op seam: the added fields took the file past the 400-line cap, and an allowlist row would have frozen the debt instead of paying it. Both halves are now well under the cap with no allowlist row. Tests: the reporter's own selector is pinned by name; the two cases above are pinned end to end through parse, adapt and match. With the mechanism removed the adapter suite is 34/42, with it 42/42.

The unknown-class entry quoted `filter.name` where every sibling entry quotes `filter.text`, the exact source substring. `! IfcWaall` therefore read back as `"IfcWaall"`, dropping the "!" and leaving the reader unable to tell which of two similar terms the adapter had rejected.

…the app The selector adapter lower-cased before testing for `qto_`, where all six other `Qto_` prefix tests in the repo (SDK, lists, ids, ifcx) compare the prefix as spelled. That made the selector the only surface answering a different question about the same set name.

`SelectorGroup` was re-exported from the package index with nothing importing it: a caller reaches a group through `SelectorQuery.groups` and narrows on `filter.kind` from there. AGENTS.md is explicit that an unused public export is permanent semver liability, so it goes before the first release rather than after. The interface itself stays, module-internal, where the parser uses it. Snapshot regenerated with `pnpm api-surface:update`; the existing `minor` changeset still describes the surface, which never shipped this name.

The Filter tab's Selector field and its "add the search query as a rule" button each carried their own copy of parse then adapt, down to the same models/activeModelId subscription taken only to reach a schema version. Two copies of a reading is two ways for the same text to be read. `readSelector` in selector-to-rules.ts is now that reading, once, and `useActiveSchemaVersion` is the subscription, once. What each caller does with the answer stays with the caller: one replaces the rule list, one appends to it, and only the caller knows which. No behaviour change.

"Add <query> as rule" fell back to `Name contains <the whole string>` whenever the adapter could not carry every term. `IfcWall, type=WT01` therefore added one rule matching zero elements, with no message: a valid selector, an empty result, nothing to read. That is the defect #4091 reported, reached from the second entry point, and a test pinned it as intended. It now applies the rules it can and names the rest in a toast, the same policy the Selector field directly above it uses; a selector that yields no rule at all reports instead of adding a guaranteed miss. Text that is not a selector — a plain `Wand` — still becomes the `Name contains` it always was. The tests assert the message reaches the DOM through a mounted Toaster, not that the handler was called.

The toolbar search box is the surface #4091's reporter actually typed into, and it answered "No results — try a name, IFC type, or full GlobalId." for a selector it does not read. A valid query, an empty list, and nothing to tell the two kinds of emptiness apart. When the query parses as a selector, the empty popover now says so and points at the Filter tab, which does run it. Tier-0 search itself is unchanged: it still matches names, types and GlobalIds, because rewiring it through the parser changes an existing surface's result set and belongs to #4094.

Two behaviours changed in this branch and the page did not say either. Quoting a name forces a literal and now works after a literal property set as well as a regex one, and the `Qto_` prefix test is case-sensitive like every other one in ifc-lite.

…hole container Both toast assertions in SearchModal.filter.promote.test.tsx matched `container.textContent`, and the promote button's own label carries the query verbatim (`Add "IfcWall, type=WT01" as rule`, 18 chars, untruncated). Deleting `toast.info` and `toast.error` left all 5 tests green: the two that exist to prove the dropped part is named could not fail. Scope them to the toast region instead. The Toaster's stack now carries `role="status"` / `aria-live="polite"`, which is the right semantics for it anyway and gives the test a stable hook. Proved by mutation: with both toast calls deleted the file was 5/5 before this change and 3/5 after; restored it is 5/5 again.

…d of misrouting it A `property` rule reads IFCPROPERTYSET rows; quantities live in their own table. `adaptProperty` only reached `Rule.quantity` for a `Qto_`-prefixed set with a numeric operator and a finite number, and everything else fell through to a property rule that reads the wrong table and added nothing to `unsupported`. Measured before this change: Qto_WallBaseQuantities.NetVolume=NULL property isNotSet -> matched EVERY element Qto_WallBaseQuantities.NetVolume!=NULL property isSet -> matched nothing Qto_WallBaseQuantities.NetVolume*=1 property contains -> matched nothing Qto_WallBaseQuantities.Note=draft property eq -> matched nothing A `Qto_` set that cannot become a quantity rule is now reported, naming the reason, and emits no rule at all. `looksLikeQuantitySet` also missed a pattern whose `Qto_` opens an alternative rather than the pattern, so `/(Qto_Wall|Qto_Slab)BaseQuantities/.NetVolume>1` became a property rule matching nothing; it is a quantity rule now. Not fixed here: making property rules read quantity rows, which is the real remedy and belongs in #4094. That leaves the non-prefixed spellings out of reach — Revit IFC2x3 writes `BaseQuantities`, ArchiCAD writes `ArchiCADQuantities` — so docs/guide/selector-syntax.md now says so instead of carrying an unqualified green row, and a test pins the gap. selector-to-rules.test.ts: 44/46 before (the two new cases fail), 46/46 after.

… names nothing "Add <query> as rule" used to turn any search text into `Name contains <text>`. Reading it as a selector first took that away from text that happens to parse: `IFC`, `ifc`, `IFC-Export`, `Level=1` and `Ø=100` all parse, produce no rule, and used to leave the user with a toast and no rule at all. Multi-word text still fell back, so the loss was invisible on the inputs anyone tried. The adapter now says which of the two it saw. `readsAsPlainText` is true when no rule came out AND every term is a class name no schema knows or an attribute with no rule behind it, which is what a plain search term parses into. `parent=Foo`, `query:…` and a GlobalId term are none of those, so they still report rather than silently becoming a Name contains that matches nothing. Warn-and-apply is unchanged wherever at least one rule survives. `FILTERABLE_ATTRIBUTES` is now the single home for the two attribute names, read by both `adaptAttribute` and the plain-text test, so the pair cannot drift. Comments trimmed where they repeated docs/guide/selector-syntax.md, keeping the module inside the 400-line limit (399). SearchModal.filter.promote.test.tsx: 5/6 before (the new case fails), 6/6 after.

…rule The empty search popover's "that reads as selector syntax, run it from the Filter tab" hint fired on `parseSelector(query).ok`. Parsing is the wrong test: an unknown 22-character GlobalId and a misspelled class such as `IfcWaall` both parse, produce no rule, and are then refused by the tab the hint sends the user to. The GlobalId case is worse than useless, since this box is where GlobalIds are searched. `selectorYieldsRules` asks the question the hint means — does the adapter get at least one rule out of it — and SearchInline reads that instead. Schema version is not passed: it only widens class expansion, and neither the unknown-class nor the unsupported-construct answer depends on it. Comments trimmed where they duplicated docs/guide/selector-syntax.md, so the module lands at 400 lines; SearchInline is unchanged in length (734). SearchInline.empty-state.test.tsx: 3/5 before (both new cases fail), 5/5 after.

When a federation contains models with different schemas, this expands a class using only the active model's schema and then applies the resulting exact type list to every model in evaluateFilterRulesFederated. For example, with an IFC4 model active and an IFC2X3 secondary model, IfcBuildingElement omits IfcReinforcingBar from the IFC2X3 results; making the IFC2X3 model active instead can incorrectly include IFC4 reinforcing bars. Preserve the class intent until per-model evaluation or otherwise expand separately for every loaded schema.

Adding regex operators to these editors exposes selector-generated rules whose valueKind: 'regex' is significant, but the Name, Material, and Classification editor callbacks rebuild rules without that field. After applying a selector such as Name=/\/tmp\//, merely switching from matches to notMatches changes /tmp/ from a regex source containing literal slashes into a slash-delimited pattern matching plain tmp; op-only edits must retain valueKind while actual value edits may clear it.

For a Qto_ selector whose operand starts with a number but contains trailing text, such as Qto_WallBaseQuantities.NetVolume>1m, Number.parseFloat returns 1, so the adapter silently runs a different numeric comparison instead of reporting the documented numeric-only requirement. Validate the complete operand before constructing the quantity rule.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Correct the empty-regex diagnostic.
When readRegex rejects Name=//, the Filter tab displays error.message. An empty regex matches every value, so it filters nothing. The current message states the opposite and can mislead users.
Proposed wording fix
- return { ok: false, error: { message: 'empty regular expression: // matches nothing', offset: start } };
+ return { ok: false, error: { message: 'empty regular expression: // matches every value, so it filters nothing', offset: start } };The existing test checks only the empty regular expression substring.

Closes #4091
A BIM coordinator typed IfcOpenShell selector syntax into ifc-lite's object filter and got nothing back. I reproduced it in the running viewer on AC20-FZK-Haus (275 elements) before writing any code:
WandIfcWallIfcWall*IfcWall, IfcSlabIfcWall[Name*=Wand]The search box is a plain substring matcher, so every selector character is matched literally and adding syntax makes it match less. The Advanced Filter is a structured rule builder whose Name operators are only eq / ne / contains / notContains / startsWith. There is no text grammar on either surface, and ifc-lite disagrees with itself: the CLI's clash selectors already accept
--a "IfcDuct*|IfcPipe*".What this adds
parseSelectorin@ifc-lite/query: a tokenizer plus recursive-descent parser over the whole IfcOpenShell filter grammar, answering with an AST or an error carrying the character offset that broke. PlusselectorToFilterRulesin the viewer adapting that AST onto the existingFilterRulemodel, a selector field in the Filter tab, regex ops in the rule model, and a docs page.The parser lives in the query package, not the viewer, because the CLI, MCP and SDK all already depend on it and should adapt the same AST rather than growing a second grammar. Accepting more than any one surface can evaluate is deliberate: the adapter names what it dropped instead of matching nothing in silence.
Working today:
IfcWall, IfcSlabwith subclasses,IfcElement, ! IfcWall,Name=D01andName=/D[0-9]{2}/,Pset_WallCommon.FireRating=2HRacross all eight operators,/Pset_.*Common/.LoadBearing=TRUE,… != NULL,material=,classification=/Pr_.*/,location="Level 3".Verified by driving the UI, not by asserting
IfcWall*now answers: Character 8 (at "*"): "*" is only valid as part of the "*=" (contains) operator; this grammar has no "*" wildcard. Use a regular expression such as /Ifc.*Wall/ instead. Rules untouched.IfcWall, /Pset_.*Common/.ThermalTransmittance>1becomes two visible, editable rules (IFC TYPE expanded to IfcWall + IfcWallElementedCase + IfcWallStandardCase, plus the property rule) and returns 5 rows in 16 ms.IfcDoor, Name=/T.*/, type=WT01applies the first two and reports "type=WT01": matching an element's type by name is not supported yet (#4094).The reporter's own selector is pinned by name in the test set, as promised in the thread.
Two review rounds, and what they caught
/simplify(4 agents) found the AST's string/regex discriminator was flattened back into ambiguous text and re-derived downstream, so a quoted literal name compiled as a regex andName=/\\/tmp\\//silently lost its slashes. That is this issue's own defect class reappearing at the adapter seam. Fixed by carrying an explicitTextKind./code-reviewthen foundQto_WallBaseQuantities.NetVolume=NULLproduced a property rule reading the pset table, which matched every element in the model. Also that promote had lost itsName containsfallback for plain text that happens to parse, and that two tests passed with the toast deleted. All fixed, each with a before/after mutation count.Measured limitation, documented not guessed
location="Level 3"matches an element contained directly in the storey but not one inside a space on that storey (elementToStorey.get(pump)isundefined), so IfcOpenShell's example 17 does not carry over. A test measures this rather than asserting it, and the docs matrix says so. #4094 tracks it, correctly scoped as a fix to the existing storey rule rather than a new rule kind.Revit's unprefixed
BaseQuantitiesand ArchiCAD'sArchiCADQuantitiesare unreachable from a selector; documented, with a test pinning the gap so it turns red when #4094 closes it.Notes for the reviewer
apps/viewer/src/lib/search/selector-to-rules.tsis at exactly 400 lines, the limit, with no allowlist row. I had it judged rather than split reflexively: it is a deep module (two public functions over 400 lines of implementation), and each candidate seam was measured and rejected. An op-map module needs 11 crossings and would import the rule vocabulary anyway; theunsupportedmessages are 17 inline literals whose value is sitting on the branch that detects the condition; a per-kind split is 4 files and 12+ crossings. When #4094 forces growth, the plan is to absorbregexProblemintofilter-ops.tsfirst (one crossing, and it co-locates two compiles of the same source that can currently disagree), then splitadaptPropertyonly if still over.Deferred on record: NameEditor / MaterialEditor / ClassificationEditor drop the
kindon an op-only toggle, which bites only when the value is itself/…/-shaped.Gates, real exit codes
