Changelog

This project follows Semantic Versioning.

v0.11.3

  • Fixes
    • Set the minimum log viewer line width to 25 so that the viewer works when the terminal forgets how wide it is

v0.11.2

  • Fixes
    • Don't crash when logging corrupt data. This is not common, but can caused when logging output from system commands.

v0.11.1

  • Fixes
    • Fix minor pagination issues with viewer
    • Adjust boot start search string to work with more Nerves systems

v0.11.0

  • New features
    • Add small TUI. Run RingLogger.viewer and type h for help to try it out. Thanks to @doawoo for this feature.

v0.10.5

  • Fixes
    • Reset potentially outdated indexes when persisted logs are loaded. Fixes the case where the persisted logs might have a much higher index than the current buffer, so every new log gets added before the loaded logs

v0.10.4

  • Fixes
    • History from loaded persistance file would be reset and lost if multiple buffers were configured outside the default buffer when RingLogger was reconfigured (at startup or runtime)

v0.10.3

  • Improvements
    • Add ability to grep text of a metadata key (thanks @levex! ❤️). See RingLogger.grep_metadata/2 for more info.

v0.10.2

  • Fixes
    • Fix remaining Elixir 1.15 warnings

v0.10.1

  • Improvements
    • Add guards to prevent some bad API inputs from crashing in places disconnected from the original calls.

v0.10.0

This latest release removes support for Elixir versions before 1.11 to fix deprecation warnings on Elixir 1.15. Elixir 1.11 to 1.14 are officially supported and Elixir 1.15 will be supported when released.

  • Improvements
    • Support for syncing the RingBuffer to disk at periodic intervals. This provides an option between a standard file logger and a fully in-memory log. This doesn't provide additional history, but does enable logs to survive reboots (assuming they were saved). It's disabled by default. See the :persist_path and :persist_seconds options for details. Thanks to @oestrich for adding this feature.

v0.9.0

This latest release removes support for Elixir versions before 1.9.

  • Improvements
    • Support multiple circular buffers and filtering based on log level. This makes it possible to separate out debug and info messages so they don't push out error messages. See the README.md for configuration examples. Thanks to @oestrich for this feature.
    • Fixed and added specs throughout

v0.8.6

  • Improvements
    • Fixed crashes when converting unicode chardata. Thanks to @x4lldux for this fix.

v0.8.5

  • Improvements
    • RingLogger.grep/2 supports :before and :after options
    • Support OTP 25

v0.8.4

  • Fixes

    • Default color enabled option now correctly evaluated at runtime for the active IO

  • Improvements

    • RingLogger.grep will now highlight matches in the output if color is enabled

v0.8.3

  • Fixes
    • Pull all application environment configuration from :logger, RingLogger rather than some from there and some from :ring_logger. Adding configuration under :ring_logger is still supported, but prints a deprecation warning. Thanks to Jason Axelson for this fix.

v0.8.2

  • Improvements
    • Circular buffer improvements are all upstream in the circular_buffer library, so this release makes it official by deleting the internal implementation and using the hex package.

v0.8.1

  • New features

    • RingLogger.next/1 now outputs a summary line that says how many log messages were recented and how many were filtered. This makes it easier to identify when the ring buffer is being overtaken by filtered log entries

  • Improvements

    • Several internal refactorings were made to reduce memory usage and the number of reductions run in the RingLogger.Server GenServer. This makes a noticeable improvement when monitoring resource usage on a device.
    • Improved tests to verify more edge conditions

v0.8.0

  • New features
    • Support filtering by OTP application. This uses the same mechanism as per-module filtering by automatically adding in all modules that are part of an OTP application. It is super useful! See the README.md. Thanks to Jon Carstons for adding this feature.
    • Support setting defaults on RingLogger clients so that you can configure things like a global default to info level messages and then only show debug messages from some applications

v0.7.0

  • New features
    • Added save/1 to save the current set of log messages in the ring buffer to a file

v0.6.1

  • Bug fixes
    • Make RingLogger.grep friendlier by supporting strings as arguments

v0.6.0

Important: RingLogger.tail is now RingLogger.next. RingLogger.tail shows the last n lines of the log (default is 10).

  • New features
    • grep greps the whole log entry rather than just the message portion. You can grep on timestamps and message levels now.
    • Functions that print log messages do the printing in the caller's context so that printing timeouts don't happen in RingLogger GenServers calls.
    • Added :none as a per-module log level to completely silence a module.
    • Added :pager option to specify a custom printer for the interactive commands.

v0.5.0

  • New features

    • Add support for changing the log levels on a per-module basis. Thanks to Matt Ludwigs for this change. See the README.md for details.
    • Add a :format option to accept a custom format function similar to how Logger supports custom formatting. Thanks to Tim Mecklem for this.
    • Bumped default ring buffer size from 100 messages to 1024.

  • Bug fixes

    • Log clients are now fully configurable. Previous versions inadvertantly limited the options that could be set.

v0.4.1

  • Bug fixes
    • Fix crash when grep'ing iodata
    • Fix init/1 callback return value when only specifying the module.

v0.4.0

  • New features
    • Added grep
    • Automatically add the backend if it's not running when using the IEx helpers

v0.3.0

Renamed LoggerCircularBuffer to RingLogger and made backwards incompatible API changes. Please review docs when upgrading.

  • New features
    • Simplified use from IEx by autostarting the Client GenServer
    • Added support for tailing logs

v0.2.0

Renamed LoggerCircularBuffer to LoggerCircularBuffer

v0.1.0

Initial release
