human-time

A command-line tool for converting time durations to human-readable formats, built using the human-time crate.

Installation

cargo install human-time-cli

Usage

human-time [OPTIONS] <TIME_DURATION>

Options

• -u, --unit <UNIT>: Specify the unit of the time duration (milli, micro). If not specified, the tool will first check the default_time_value_units in the config file. If no config file exists or it doesn't specify a unit, it defaults to seconds.
• -c, --config: Specify if there is a config file. (See Configuration section for details on creating a config file.)

Examples

• Convert 120 seconds to human-readable format:

  human-time 120
  

  Output:

  2m
  

• Convert 500 milliseconds to human-readable format:

  human-time -u milli 1500
  

  Output:

  1s,500ms
  

• Convert 7200 seconds using a config file:

  human-time 7200 -c
  

  (See Configuration section for details on creating a config file.)

• Reading from stdin:

  echo 3600 | human-time
  

  Output:

  1h
  

Configuration

The human-time tool supports a configuration file named human-time.toml. It can be placed in either of the following locations:

1. The same directory as the human-time executable.
2. Your home directory.

If a config file is found, the tool will use it to customize the output format and units. If no config file is found, default values are used.

human-time.toml Example

default_time_value_units = "seconds" # Default unit if -u is not provided

[formatting]
format = "{} {}"  # Format string for each time unit. Must contain exactly two "{}" placeholders. The first is for the time value, the second for the unit.
delimiter_text = ", " # Delimiter between time units when multiple units are displayed

[units]
d = "day(s)"
h = "hour(s)"
m = "minute(s)"
s = "second(s)"
ms = "millisecond(s)"
us = "microsecond(s)"

Configuration Options

• default_time_value_units: The default unit to use if the -u or --unit option is not provided on the command line. Valid values are "seconds", "milliseconds", and "microseconds".
• formatting.format: The format string used to display each time unit. It must contain exactly two {} placeholders. The first {} is replaced with the numeric time value, and the second {} is replaced with the unit string.
• formatting.delimiter_text: The string used to separate multiple time units when the duration is expressed in more than one unit (e.g., "1 hour, 30 minutes").
• units: A table of unit strings. Singular/plural forms are automatically handled based on the time value if "(s)" is included (e.g., "second(s)").

Input from Stdin

If no TIME_DURATION is provided as a command-line argument, human-time will attempt to read the duration from standard input (stdin). This allows you to pipe values to the command.

Building from Source

If you want to build human-time from source, you'll need to have Rust and Cargo installed.

1. Clone the repository.
2. Navigate to the project directory.
3. Run cargo build.

The executable will be located in the target/debug directory.
