fix(explain): stop bare variable references at hyphens (#219) - #306
Conversation
Match RouterOS token boundaries for bare variable references while preserving quoted hyphenated names. Re-scan the remainder as expression input so subtraction operands remain independently resolvable, and repin the token census. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

Pull request overview
This PR corrects explain symbol resolution to match RouterOS device highlight behavior for hyphen boundaries: a bare $name-with-hyphen reference now stops at the hyphen, while the quoted $"name-with-hyphen" spelling preserves the full name.
Changes:
- Update
$reference scanning so-terminates bare references (and downstream scanning can independently resolve expression operands). - Add/adjust unit tests to assert the new bare-vs-quoted hyphen behavior and token partition expectations.
- Repin the offline token census fixture and update the
explaincommand documentation to reflect the corrected contract.

In `@src/explain/symbols.ts`:
- Around line 83-86: Align braced-reference parsing in readRef and lookup with
the documented S19 contract so unquoted ${set-dns} cannot resolve a hyphenated
declaration, while quoted ${"set-dns"} follows the supported quoted-reference
behavior. Add coverage in test/unit/explain-symbols.test.ts, update the
corresponding cases in test/fixtures/explain/symbols.json, and revise the rule
documentation in src/explain/symbols.ts and commands/explain/README.md to define
these outcomes.

Align the offline symbol resolver with CHR: RouterOS rejects ${...} at the opening brace, so braced contents cannot resolve declarations. Add explicit regressions, repin the token census, and replace the value-token test cast with complete typed fixtures.
