module Rigor::ModuleGraph::EdgeIO

JSONL reader / writer for Edge rows. Used by the plugin collector and the +rigor-module-graph+ renderer subcommands.

Public Instance Methods

Source

# File lib/rigor/module_graph/edge.rb, line 159
def read(io)
  edges = []
  io.each_line do |line|
    line = line.strip
    next if line.empty?

    row = JSON.parse(line)
    edges << Edge.build(
      from: row.fetch("from"),
      to: row.fetch("to"),
      kind: row.fetch("kind"),
      path: row["path"],
      line: row["line"],
      column: row["column"],
      confidence: row.fetch("confidence", "syntax"),
      raw: row["raw"]
    )
  end
  edges
end

Parse JSONL from +io+ into Edge instances. Blank lines are skipped. Missing +confidence+ defaults to +“syntax”+ so the format stays backwards-compatible with earlier outputs.

write (edges, io)

Source

# File lib/rigor/module_graph/edge.rb, line 145
def write(edges, io)
  seen = {}
  edges.each do |edge|
    key = edge.dedup_key
    next if seen[key]

    seen[key] = true
    io.puts(JSON.generate(edge.to_h))
  end
end

Stream +edges+ to +io+ as JSONL, deduping by Edge#dedup_key so re-runs don’t accumulate duplicate rows.
