ctxcli: Extend golang context to CLI

ctxcli is a Go library extending the standard context with handling for OS signals.

Features

• Create a child context that cancels when an OS signal like SIGINT is received.
• Helper functions to exit or panic when the provided context is cancelled.
• Consistent API with the context standard library.

Example

package main

import (
    "context"
    "log"
    "time"
    "github.com/jhulten/go-ctxcli"
)

func main() {
    ctx := context.Background()
    ctx = ctxcli.WithInterrupt(ctx)

    for {
        log.Print(".")
        time.Sleep(500 * time.Millisecond)
        ctxcli.ExitIfCancelled(ctx)
    }
}
