# `Gno.CommitLogger`
[🔗](https://github.com/rdf-elixir/gno/blob/v0.1.0/lib/gno/commit_middlewares/logger.ex#L1)

A `Gno.CommitMiddleware` for logging commit operations.

Logs key commit events and collects log entries from other middlewares
through the processor's `:log` assign.

## Manifest Configuration

    @prefix gno: <http://gno.app/> .

    <Service> a gno:Service
        ; gno:serviceCommitOperation <CommitOperation>
        # ...
    .

    <CommitOperation> a gno:CommitOperation
        ; gno:commitMiddleware ( <Logger> )
    .

    <Logger> a gno:CommitLogger
        ; gno:commitLogLevel "debug"       # optional (default: "info")
        ; gno:commitLogChanges true        # optional (default: false)
        ; gno:commitLogMetadata true       # optional (default: false)
    .

## Options

- `:log_level` (`gno:commitLogLevel`) - the log level to use (default: `"info"`)
- `:log_states` (`gno:commitLogStates`) - list of states to log; `"all"` logs all
  states, `"none"` logs no state changes (default: `["initializing", "completed"]`)
- `:log_changes` (`gno:commitLogChanges`) - whether to log changeset details (default: `false`)
- `:log_metadata` (`gno:commitLogMetadata`) - whether to log commit metadata (default: `false`)
