Some example features: - Parsing and formatting numbers, file sizes, pathnames and timespans in simple, human friendly formats. - Easy to use timers for long running operations, with human friendly formatting of the resulting timespans. - Prompting the user to select a choice from a list of options by typing the option's number or a unique substring of the option. - Terminal interaction including text styling (ANSI escape sequences), user friendly rendering of usage messages and querying the terminal for its size. The `humanfriendly` package is currently tested on Python 2.6, 2.7, 3.4, 3.5, 3.6 and PyPy (2.7) on Linux and Mac OS X. While the intention is to support Windows as well, you may encounter some rough edges. .. contents:: :local: Getting started --------------- It's very simple to start using the `humanfriendly` package:: >>> import humanfriendly >>> user_input = raw_input("Enter a readable file size: ") Enter a readable file size: 16G >>> num_bytes = humanfriendly.parse_size(user_input) >>> print num_bytes 16000000000 >>> print "You entered:", humanfriendly.format_size(num_bytes) You entered: 16 GB >>> print "You entered:", humanfriendly.format_size(num_bytes, binary=True) You entered: 14.9 GiB Command line ------------ .. A DRY solution to avoid duplication of the `humanfriendly --help' text: .. .. [[[cog .. from humanfriendly.usage import inject_usage .. inject_usage('humanfriendly.cli') .. ]]] **Usage:** `humanfriendly [OPTIONS]` Human friendly input/output (text formatting) on the command line based on the Python package with the same name. **Supported options:** .. csv-table:: :header: Option, Description :widths: 30, 70 "``-c``, ``--run-command``","Execute an external command (given as the positional arguments) and render a spinner and timer while the command is running. The exit status of the command is propagated." ``--format-table``,"Read tabular data from standard input (each line is a row and each whitespace separated field is a column), format the data as a table and print the resulting table to standard output. See also the ``--delimiter`` option." "``-d``, ``--delimiter=VALUE``","Change the delimiter used by ``--format-table`` to ``VALUE`` (a string). By default all whitespace is treated as a delimiter." "``-l``, ``--format-length=LENGTH``","Convert a length count (given as the integer or float ``LENGTH``) into a human readable string and print that string to standard output." "``-n``, ``--format-number=VALUE``","Format a number (given as the integer or floating point number ``VALUE``) with thousands separators and two decimal places (if needed) and print the formatted number to standard output." "``-s``, ``--format-size=BYTES``","Convert a byte count (given as the integer ``BYTES``) into a human readable string and print that string to standard output." "``-b``, ``--binary``","Change the output of ``-s``, ``--format-size`` to use binary multiples of bytes (base-2) instead of the default decimal multiples of bytes (base-10)." "``-t``, ``--format-timespan=SECONDS``","Convert a number of seconds (given as the floating point number ``SECONDS``) into a human readable timespan and print that string to standard output." ``--parse-length=VALUE``,"Parse a human readable length (given as the string ``VALUE``) and print the number of metres to standard output." ``--parse-size=VALUE``,"Parse a human readable data size (given as the string ``VALUE``) and print the number of bytes to standard output." ``--demo``,"Demonstrate changing the style and color of the terminal font using ANSI escape sequences." "``-h``, ``--help``",Show this message and exit. .. [[[end]]] A note about size units ----------------------- When I originally published the `humanfriendly` package I went with binary multiples of bytes (powers of two). It was pointed out several times that this was a poor choice (see issue `#4`_ and pull requests `#8`_ and `#9`_) and thus the new default became decimal multiples of bytes (powers of ten): +------+---------------+---------------+ | Unit | Binary value | Decimal value | +------+---------------+---------------+ | KB | 1024 | 1000 + +------+---------------+---------------+ | MB | 1048576 | 1000000 | +------+---------------+---------------+ | GB | 1073741824 | 1000000000 | +------+---------------+---------------+ | TB | 1099511627776 | 1000000000000 | +------+---------------+---------------+ | etc | | | +------+---------------+---------------+ The option to use binary multiples of bytes remains by passing the keyword argument `binary=True` to the `format_size()`_ and `parse_size()`_ functions.
