Fixed

• Fix 'Initialization of 'UnsafePointer' results in a dangling pointer' compiler warning.
• Fixed crash in AsyncWriterProxy buffering when buffer is empty.

Added

• Added OutputStreamFormatter protocol to define formatters for use with byte output stream type Writers.
• Added TextFormat, an implementation of a OutputStreamFormatter that formats its output based on a supplied template (this is the default formatter for Console and File output).
• Added JSONFormat, an implementation of a OutputStreamFormatter that formats its output in standard JSON format.
• Added OutputStreamWriter protocol to define types that write byte streams to their output and accept OutputStreamFormatter types to format the output.
• Added LogEntry tuple type to Writer defining the formal types that a Writer writes.
• Added .buffer option for .async concurrency modes to allow for buffering when the writer is not available to write to its endpoint.
• Added protected data monitoring for FileWriter.Strategy.fixed on iOS for use with AsyncConcurrencyModeOption.buffer(writeInterval:strategy:). This allows TraceLog to be started up before protected data is available on iOS.

Upated

• Requires Swift 5 for compilation.
• Changed parameters to .async to include options for configuration of the mode (.async(options: Set<AsyncConcurrencyModeOption>) and .async(Writer, options: Set<AsyncConcurrencyModeOption>)).
• Changed Writer protocol log() method to write(_ entry: Writer.LogEntry) to make it easier to process messages by writers and formatters.
• Changed Writer return to Swift.Result<Int, FailedReason> to return instructions for TraceLog for buffering and error recovery.
• Changed ConsoleWriter to accept new OutputStreamFormatter instances allowing you to customize the output log format (default is TextFormat.)
• Changed FileWriter public interface
  • FileWriter now requires the log directory be passed in, removing default value of ./.
  • Removed the fileConfiguration parameter replacing with new strategy enum.
  • It now accepts the new OutputStreamFormatter instances allowing you to customize the output log format (default is TextFormat.)
• Changed FileWriter archive file name date format to "yyyyMMdd-HHmm-ss-SSS" (This was done for maximum compatibility between platforms and can be overridden in the FileConfiguration object passed at init.)
• TextFormat to add var encoding: String.Encoding { get } requirement.
• JSONFormat to add var encoding: String.Encoding { get } requirement.
• Renamed AsyncOption to AsyncConcurrencyModeOption.
• Changed OutputStreamFormatter, it now requires var encoding: String.Encoding { get }.
• Renamed FileWriter.FileStrategy to FileWriter.Strategy.
• Renamed FileWriter.Strategy.RotateOption to FileWriter.Strategy.RotationOption.

Removed

• Removed TraceLogTestHarness module.

Fixed

• Fixed logTrace when no trace level is passed. It's now the correct default value of 1 instead of 4 (issue #58).

Updated

• Corrected availability of FileWriter and FileStrategyRotate so that they compile correctly on iOS.

Added

• Added protected data monitoring for FileWriter.Strategy.fixed on iOS for use with AsyncConcurrencyModeOption.buffer(writeInterval:strategy:). This allows TraceLog to be started up before protected data is available on iOS.

Added

• Added extensive HTML documentation including user guides and a complete API reference.

Changed

• Renamed AsyncOption to AsyncConcurrencyModeOption.
• Changed OutputStreamFormatter, it now requires var encoding: String.Encoding { get }.
• Renamed FileWriter.FileStrategy to FileWriter.Strategy.
• Renamed FileWriter.Strategy.RotateOption to FileWriter.Strategy.RotationOption.

Removed

• Removed TraceLogTestHarness module.

Fixed

• Adding missing newline to ConsoleWriter output (issue #55).

Added

• Added mode to TraceLog.configuration to allow direct, async, or sync mode of operation. Sync & direct mode are useful for use cases that have short-lived processes (scripts) or require real-time logging.
• Added ability to set the concurrency mode individually for each Writer.
• Added FileWriter class for writing to local log files.
• Added TestHarness to assist developers in testing their own Writer types.
• Added shell utility to assist in testing Writer types.
• Added TraceLogTestTools module/library to allow use of new TestHarness and other Utilities.

Removed

• Removed all Xcode projects, Xcode projects are now generated using Swift Package Manager.
• Dropped iOS 8 support.

Removed

• Removed the UnifiedLoggingWriter and instead using external AdaptiveSystemLogWriter which adapts to various platforms for latest system log.

Added

• Added UnifiedLoggingWriter for Apple Unified Logging system logging using TraceLog.
• Added mode to TraceLog.configuration to allow direct, async, or sync mode of operation. Sync & direct mode are useful for use cases that have short-lived processes (scripts) or require real-time logging.

Removed

• Removed all Xcode projects, Xcode projects are now generated using Swift Package Manager.
• Dropped iOS 8 support.

Updated

• Xcode projects to be swift 4.1 compatible.

Removed

• Removed deprecated TLLogger.configure(). Use TraceLog.configure in swift instead.
• Removed deprecated TLLogger.configureWithEnvironment. Use TraceLog.configure in swift instead.

2.2.0

Updated

• Change build environment requirements to xcode9.2 / Swift 4.0.3 (note: this is ust the build, targets are still the same).

Added

• Log level OFF to allow turning off logging for a specific level (global, prefix, tag).

Updated

• Various documentation updates.

Added

• Added required tests to bring coverage back to 100%.

Updated

• Deprecated TLLogger.configure and TLLogger.configureWithEnvironment. Use TraceLog.configure in swift instead.
• Changed Vagrant file to include libpython2.7 required for Swift REPL.

Fixed

• Removed unnecessary String with formatters call that can result in a crash if the interpolated string includes formatter options that the String(format:) function will never have matching parameters for.

Added

• The OS_ACTIVITY_MODE environment variable to iOS and OSX Example.
• CHANGELOG.md

Updated

• Inline documentation for all public classes and functions.
• Combined TraceLog.configure func's into one with the same symantics as the 3 previous funcs.
• iOS example application converting it to Swift.

Fixed

• Cocoadocs documentation creation.

This release includes the addition of:

• Installable Writers to allow custom writers to be used to write to various output devices/end points such as HTTP services, sys log, files, etc
• Ability to configure the environment statically at the beginning of the application
• Swift 3 Compatibility
• Swift Package Manager support
• Linux support
• Now written in Swift 3
