I was inspired by samwho/spacer, which was written in Rust, and I really liked it. I decided to write it in Go, and here we go! :)
tailer is a simple CLI tool to insert lines when command output stops.
go install github.com/hionay/tailer/cmd/tailer@latestHere are the commands and flags you can use with tailer:
COMMANDS:
exec, e execute a command and tail its output
help, h Shows a list of commands or help for one command
GLOBAL OPTIONS:
--no-color disable color output (default: false)
--after value, -a value duration to wait after last output (default: 1s)
--dash value, -d value dash character to print (default: "─")
--help, -h show help
--version, -v print the version
You can use tailer to execute a command with exec without the need for piping.
$ tailer exec "python3 -m http.ser
