Ragex.Analysis.Cache (Ragex v0.9.1)

View Source

Persistence layer for code analysis results (issues).

Caches issue discovery results (dead code, security, smells, duplicates, etc.) alongside file fingerprints. On load, compares stored fingerprints with current file state to determine cache freshness.

Data is stored at ~/.cache/ragex/<project_hash>/analysis.etf.

Usage

# Save analysis results
:ok = Analysis.Cache.save(issues, "/path/to/project")

# Load cached results (validates freshness)
{:ok, issues} = Analysis.Cache.load("/path/to/project")
{:stale, cached_issues, changed_files} = Analysis.Cache.load("/path/to/project")

# Check cache freshness
Analysis.Cache.fresh?("/path/to/project")

load(path)

@spec load(String.t()) ::
  {:ok, map()} | {:stale, map(), [String.t()]} | {:error, term()}

Loads cached analysis results and validates freshness.

Parameters
