The search command supports filter options (`--language`, `--repo`, `--type`, `--limit`) and output options (`--json`, `--quiet`); see [CLI Reference](cli-reference.md#megabrain-search) for details. When you run an ingest (e.g. `megabrain ingest --source github --repo owner/repo`), progress is streamed in the terminal. Use `--verbose` for detailed progress and stack traces on errors. ```bash cd backend diff --git a/docs/implemented-features.md b/docs/implemented-features.md index 4aef6e9..8efdcf2 100644 --- a/docs/implemented-features.md +++ b/docs/implemented-features.md @@ -408,4 +408,10 @@ CLI command to search the MegaBrain index from the command line. - Help text: `megabrain search --help` shows description and usage - Unit tests: `SearchCommandTest` (plain JUnit 5) for command name, `--help` output, execute with one query arg, blank query exit 2 -**Not Yet Implemented:** T2 (filter options), T3 (result formatting), T4 (syntax highlighting), T5 (JSON output), T6 (extended command tests). +**Completed (T2):** +- Filter and output options: `--language`, `--repo`, `--type` (entity_type), `--limit` (default 10), `--json` (default false), `--quiet` (default false).

Pretty-printing uses `writerWithDefaultPrettyPrinter()` when TTY and not quiet and not `--no-color`; compact when piped or `--no-color`. Written to `spec.commandLine().getOut()` and flushed. No new DTOs; `SearchResponse`/`SearchResult` are Jackson-friendly. - **Tests:** `SearchCommandTest`: with `--json` parse stdout as JSON object, assert root has `results`, `total`, `page`, `size`, `query`, `took_ms`, `facets` and one result has `source_file`, `entity_name`, `score`; with `--json --quiet` parse as JSON array, assert length and element fields; empty results: full JSON has `results=[]`, `total=0`, quiet is `[]`. Use `ObjectMapper.readValue(stdout.trim(), ...)`; no exact string assertions. -**Not Yet Implemented:** T6 (extended command tests). +**Completed (T6):** +- **Tests:** Unit tests for SearchCommand covering option parsing, validation, output formatting, JSON mode, and help text using Picocli `CommandLine.execute()` and mocked `SearchOrchestrator`. Council-recommended tests: orchestrator failure (exit 1, stderr "Search failed"), JSON with null ObjectMapper (exit 1), JSON serialization failure (mocked IOException), NO_COLOR env (useColor false via SystemStubs), blank/uppercase filter normalization (--language " " skipped, JAVA → java), --quiet human-readable (formatter quiet true, one line per result), JSON with non-empty facets. Additional: SearchResultFormatterTest, CliSyntaxHighlighterTest. Package `io.megabrain.cli` line and instruction coverage >80% (JaCoCo); SearchCommand 94% instructions, 75% branches. diff --git a/features/user-stories/epic-04-api-cli/US-04-05-cli-search-command-tasks.md b/features/user-stories/epic-04-api-cli/US-04-05-cli-search-command-tasks.md index 1c2a65e..0712b76 100644 --- a/features/user-stories/epic-04-api-cli/US-04-05-cli-search-command-tasks.md +++ b/features/user-stories/epic-04-api-cli/US-04-05-cli-search-command-tasks.md @@ -77,14 +77,14 @@ - **Description:** Create unit tests for SearchCommand.
