eventlog-socket-0.1.2.0: eventlog-socket.cabal

cabal-version:      2.2
name:               eventlog-socket
version:            0.1.2.0
synopsis:           Stream GHC eventlog events to external processes.
description:
  The @eventlog-socket@ package lets you stream the GHC eventlog over a socket in realtime.
  This package exports both a Haskell API (from "GHC.Eventlog.Socket") and a C API (from [@eventlog_socket.h@](./docs/c/index.html)).
  For most uses, the Haskell API is sufficient.
  However, if you want to instrument your application from a C main or install custom command handlers you need the C API.
