peekie coverage

Emit code coverage from a .xcresult bundle as a hierarchical JSON structure (or list).

Synopsis

peekie coverage <xcresult-path> [flags]

Flags

Flag	Default	Notes
<xcresult-path>	—	Required positional. Path to the .xcresult bundle.
--format json|list	json	Output format.
-v, --verbose	false	Debug-level logging to stderr.

There is no --include flag on peekie coverage. Filter modules/files with jq.

Output shape

--format json (default)

{
  "coverage": 0.6234,
  "modules": [
    {
      "name": "Calculator",
      "coverage": 0.71,
      "coveredLines": 167,
      "totalLines": 233,
      "files": [
        {"name": "Calculator.swift", "path": "/.../Calculator.swift", "coverage": 0.71, "coveredLines": 167, "totalLines": 233}
      ]
    },
    {
      "name": "Networking",
      "coverage": 0.42,
      "coveredLines": 84,
      "totalLines": 200,
      "files": [
        {"name": "Client.swift", "path": "/.../Networking/Client.swift", "coverage": 0.50, "coveredLines": 50, "totalLines": 100},
        {"name": "Endpoint.swift", "path": "/.../Networking/Endpoint.swift", "coverage": 0.34, "coveredLines": 34, "totalLines": 100}
      ]
    }
  ]
}

• Top-level coverage is overall percentage as 0.0–1.0 (multiply by 100 for percent).
• Each module and file carries coverage, coveredLines, totalLines.
• path is the absolute source-file path captured at build time.

--format list

Human-readable, indented by module → file. Good for terminal, not for piping.

Recipes

Overall coverage as a percentage integer

peekie coverage Tests.xcresult | jq '.coverage * 100 | floor'

Overall coverage with one decimal place

peekie coverage Tests.xcresult | jq '(.coverage * 1000 | floor) / 10'

(.coverage * 1000 | floor) / 10 keeps it pure jq — no bc, no printf. For two decimals, use * 10000 | floor) / 100.
