streamtabs

This makes it easy to follow noisy logs without rerunning commands.

You pipe text in, pass filters as arguments, and get:

• tab 0: (all) lines
• tabs 1..N: one tab per filter

Install

From crates.io:

cargo install streamtabs

This installs both binaries:

• streamtabs
• st (short alias)

Quick Start

Run with at least one filter:

tail -f app.log | st error warn info

More Examples

cat ./file.txt | st foo bar

log stream --style compact | st Error Fault WindowServer

Controls

• Tab: next tab
• 0 to 9: jump to tab number
• Space: pause/resume
• q or Ctrl+C: quit
• Mouse click tab: switch tabs
• Shift+mouse click tab: toggle that tab in the current OR view
• Mouse click line: highlight that line across tabs
• d: cancel highlighted line

Notes

• Run in a terminal (stdout must be a TTY).
• st requires at least one filter argument.
• Each tab stores up to 5000 lines.
