About tailspin
🌀 A log file highlighter
tailspin 7.0.0
🌀 A log file highlighter
- By bensadeh
- Open Source
- Updated Jul 14, 2026
What's new in 7.0.0
Added
- --extras jvm-stack-trace highlights JVM stack traces (Java, Kotlin, Scala, etc.)
- TAILSPIN_EXTRAS environment variable to set extras without the --extras flag
Performance
- Cache ANSI style prefixes in a thread-local, avoiding per-line allocation in the render pipeline
Fixed
- Theme parse and read errors now include the path of the offending file
- Reject unknown fields in theme.toml so they surface as errors instead of being silently ignored
- --exec no longer tears down the pager the moment the spawned subprocess exits
- Kill the pager when tailspin exits due to a stream error, instead of leaving it orphaned
- Overriding builtin keywords in theme.toml should always take precedence over the builtin ones
- (#267)
