feat(#20): add mystery-object lint by VasilevNStas · Pull Request #1241 · objectionary/lints

What

A new Java-based lint mystery-object is added. It is registered in
MonoLints together with the other hand-coded lints (ascii-only,
reserved-name). The full set of artifacts:

src/main/java/org/eolang/lints/LtMystery.java — the lint implementation
src/main/resources/org/eolang/motives/names/mystery-object.md — the motive
src/test/java/org/eolang/lints/LtMysteryTest.java — unit tests
src/test/resources/org/eolang/lints/*.eo — EO fixtures used by the tests

Why

Consider this program:

[] > foo
  bar 42 > x

The object bar is neither defined in the program, nor imported via
+alias, nor one of the org.eolang objects. Such a call is almost always
a typo in the object name. Still, the parser happily compiles it into a
bare Φ.bar reference and nobody complains. The program reaches the
compile/run pipeline and fails there with an obscure error, far away from
the actual mistake.

This lint detects exactly that situation and reports it as an error
right at the source line.

How it works

The parser resolves any object application into a base attribute. There
are three interesting shapes:

Φ.org.eolang.io.stdout — a qualified path (result of +alias or a
fully-qualified name). Always legitimate, never reported.
Φ.number, Φ.bytes, etc. — references to prime org.eolang objects.
Legitimate, but only when the name is really one of the reserved top-level
objects of the home repository.
Φ.bar — a bare single-name reference. This is the suspicious case.

The lint walks every //o[@base] element and applies the simple-name
pattern ^Φ\.[a-z][a-z0-9_-]*$. Any element that matches must prove its
right to exist:

The name is declared somewhere in the current program, i.e. there is a
//o[@name='bar'] node in the same XMIR — a legitimate local object, or
The name is present in ReservedNames — the CSV of the org.eolang
top-level objects, generated from the home repository on the reserved
build profile.

Everything else is a mystery object and gets an error defect.

Aliased objects need no special handling: the parser resolves an alias into
a dotted path (Φ.org.eolang.io.stdout), which never matches the simple
one-word pattern, so they are excluded by construction.

Why not an XSL lint

The decision on "is NAME a legitimate org.eolang object" depends on the
runtime list from the home repository (ReservedNames, backed by
reserved.csv generated on the reserved Maven profile). XSL transforms
cannot read that runtime data, while a Java lint can — this is the same
reason the existing reserved-name lint is implemented in Java.

Robustness against a missing reserved list

reserved.csv exists only when the reserved profile is active (CI does
this in a dedicated reserved.yml workflow). In the default mvn test
run the map is empty. The lint handles this gracefully: with an empty list
it returns no defects. The full behavior matrix is exercised in the
@Tag("reserved") integration test (scansMysteryFromHome), which runs
against the real home data in CI.

Tests

catchesMysteryObject — bar with no definition is caught
reportsCorrectMessageForMysteryObject — message names the object
allowsDeclaredObject — local bar declaration is fine
allowsAliasedObject — +alias import is fine
allowsCanonicalObject — org.eolang literal (42) is fine
allowsAllObjectsDeclaredInline — all inline declarations are fine
scansMysteryFromHome (@Tag("reserved")) — integration against the
real reserved list from home

Both mvn test (592 tests) and mvn clean install -Pqulice pass.

@VasilevNStas Could u update this PR, please?

VasilevNStas · 2026-09-03T07:22:56Z

@volodya-lombrozo Updated — the branch is rebased on the current master and the conflict is resolved.

What changed:

Rebased on master (104 commits behind); the MonoLints conflict was resolved by keeping master’s javaLints() (which now includes LtTestNotVerb and the IOException handling) and adding LtMystery to that list — the diff against master is now exactly the 9 files of this PR.
Dropped javadoc from private methods in LtMystery and LtMysteryTest (qulice 0.32.0 NoJavadocForPrivateMethodsCheck).

Verified locally: mvn clean install -Pqulice (1017 rules) and mvn clean test (663 tests, incl. 6 LtMysteryTest cases) pass.
