# `Snakepit.RunID`
[🔗](https://github.com/nshkrdotcom/snakepit/blob/v0.13.0/lib/snakepit/run_id.ex#L1)

Generates short, unique BEAM run identifiers.

Format: 7 characters, base36-encoded
Components: timestamp (5 chars) + counter (2 chars)
Example: "k3x9a2p"

These IDs are embedded in Python process command lines for reliable
identification and cleanup across BEAM restarts.

# `extract_from_command`

Extracts run ID from a process command line.
Supports both --snakepit-run-id and --run-id formats.

## Examples

    iex> cmd = "python3 grpc_server.py --snakepit-run-id k3x9a2p --port 50051"
    iex> Snakepit.RunID.extract_from_command(cmd)
    {:ok, "k3x9a2p"}

    iex> Snakepit.RunID.extract_from_command("no run id here")
    {:error, :not_found}

# `generate`

Generates a unique 7-character run ID.

## Examples

    iex> run_id = Snakepit.RunID.generate()
    iex> String.length(run_id)
    7
