ConfigErrorFormatter

class ConfigErrorFormatter(useColors: Boolean = true)

Renders a list of ConfigError instances into a human-readable, optionally ANSI-colored report.

Errors are grouped by their concrete type (e.g. InvalidValue, UnknownKey) and printed with their dot-separated paths highlighted. A trailing summary line counts how many fields fell back to default values due to ConfigError.OutOfRange or ConfigError.PatternMismatch.

Example output (with colors disabled for illustration):

3 config error(s) found in my-service:

  [InvalidValue]
    server.port: Invalid value 'abc', expected Int

  [UnknownKey]
    databse: Unknown key 'databse' - did you mean 'database'?

  [OutOfRange]
    server.maxThreads: Value 9999 is out of range [1.0, 512.0], fell back to 16

  1 field(s) fell back to default values.

Usage:

val formatter = ConfigErrorFormatter(useColors = true)
val report = formatter.format(collector.all(), configName = "my-service")
System.err.print(report)
