Turn the hardcoded straight-line sweep into a strategy system behind three
seams so new patterns are easy to add and, for the first time, testable
without nut.js or a real screen:
- src/device.ts: injectable Device seam over nut.js (autoDelayMs lives
here now); the only module that touches the native lib.
- src/strategies.ts: pure per-pattern path generators + registry + lenient
name resolution. Ships line, diagonal, jitter, walk,
arc, figureEight.
- src/executor.ts: single executePath driver owning bounds policy
(abort/clamp/reflect), pacing, interrupt detection, and
restore-on-clean.
keeper.ts's simulateActivity now selects a strategy and delegates to the
executor; the default `line` pattern is byte-for-byte the previous behavior.
New config surface, layered CLI > file > default with strict validation:
- -p/--pattern <name> movement strategy (names matched case/-/_-insensitive)
- -s/--step-size <px> pixels per step; stepCount is now a step *count*
Robustness for the new edge-seeking patterns: interrupt detection compares
against the last commanded (rounded) point with a 2px tolerance, and
clamp/reflect stay a couple pixels off the screen edge, so sub-pixel cursor
placement on scaled/multi-monitor displays isn't misread as user activity.
jitter's radius scales with sweep length so it moves at the default stepSize.
Tests: new suites for strategies, the executor (all bounds policies,
rounding, interrupt, tolerance, pacing), and the keeper loop; config and
configFile suites extended for pattern/stepSize. editor.test.ts moved to
tests/ for consistency. 64 pass.
src/ now contains only source code; tests live alongside it under
tests/. Bun's test runner discovers '**/*.test.ts' so no test-runner
config change is needed.
Changes:
- tests/config.test.ts (was src/config.test.ts)
- tests/configFile.test.ts (was src/configFile.test.ts)
- Imports updated: ./config.ts -> ../src/config.ts (likewise for
configFile.ts and errors.ts).
- tsconfig.json include adds 'tests/**/*.ts' so tsc type-checks
the test files too.
All 25 tests still pass; tsc clean.
