Parse time durations with support for days

haproxytime

haproxytime is a command-line utility designed to facilitate the conversion of human-readable time durations into a format precisely represented in milliseconds, tailored specifically for HAProxy configurations.

This tool is useful for developers and administrators who work with HAProxy, providing a straightforward mechanism to ensure that timeout configurations are accurately specified in a format that HAProxy can understand. Whether you're inputting durations directly or piping them from standard input, haproxytime streamlines the process of dealing with time durations, supporting a wide range of units from days to microseconds. With features to display durations in both machine- and human-readable formats, as well as the ability to print the maximum HAProxy timeout value, haproxytime minimises the risk of configuration errors in your HAProxy setup.

Install

To install without versioning information:

$ go install github.com/frobware/haproxytime@latest

To install with versioning information:

$ go install -ldflags "-X 'main.buildVersion=$(git describe --tags --abbrev=8 --dirty --always --long)'" github.com/frobware/haproxytime@latest

Usage

haproxytime - Convert human-readable time duration to millisecond format

General Usage:
  haproxytime [-help] [-v]
  haproxytime [-h] [-m] [<duration>]

Usage:
  -help Show usage information
  -v	Show version information
  -h	Print duration value in a human-readable format
  -m	Print the maximum HAProxy timeout value
  <duration>: value to convert. If omitted, will read from stdin.

The flags [-help] and [-v] are mutually exclusive with any other
options or duration input.

Available units for time durations:
  d   days
  h:  hours
  m:  minutes
  s:  seconds
  ms: milliseconds
  us: microseconds

A duration value without a unit defaults to milliseconds.

Examples:
  haproxytime -m           -> Print the maximum HAProxy duration.
  haproxytime 2h30m5s      -> Convert duration to milliseconds.
  haproxytime -h 4500000   -> Convert 4500000ms to a human-readable format.
  echo 150s | haproxytime  -> Convert 150 seconds to milliseconds.
