stack

A cli tool to prettify stacktrace in json logs.

Why to write this tool?

When we read the stacktrace info from json logs, it's hard to read without pretty print.

Usage

1. From stdin

{"@timestamp":"2023-01-20T19:56:57.806+08:00","content":"panic\ngoroutine 1 [running]:\nruntime/debug.Stack()\n\t/usr/local/go/src/runtime/debug/stack.go:24 +0x64\ngithub.com/zeromicro/go-zero/core/logx.writeStack({0x14000092008, 0x5})\n\t/Users/kevin/Develop/go/opensource/go-zero/core/logx/logs.go:457 +0x48\ngithub.com/zeromicro/go-zero/core/logx.ErrorStack({0x140002dff58?, 0x1400010e000?, 0x0?})\n\t/Users/kevin/Develop/go/opensource/go-zero/core/logx/logs.go:113 +0x24\nmain.main()\n\t/Users/kevin/Develop/go/opensource/go-zero/adhoc/log/main.go:17 +0x80\n","level":"error"}

$ tail -f error.log | stack -i

main.main()

2. From clipboard
