dbacl is a fast Bayesian text and email classifier. It builds a variety of language models using maximum entropy (minimum divergence) principles, and these can then be used to categorize input data automatically among multiple categories.

Nkf is yet another kanji code converter among networks, hosts and terminals. It converts input kanji code to designated kanji code such as ISO-2022-JP, Shift_JIS, EUC-JP, UTF-8, UTF-16 or UTF-32.

The Recode library converts files between character sets and usages. It recognises or produces over 200 different character sets (or about 300 if combined with an iconv library) and transliterates files between almost any pair. When exact transliteration are not possible, it gets rid of offending characters or falls back on approximations. The recode program is a handy front-end to the library.

odt2txt is a command-line tool which extracts the text out of OpenDocument Texts, as produced by OpenOffice.org, KOffice, StarOffice and others.

odt2txt can also extract text from some file formats similar to OpenDocument Text, such as OpenOffice.org XML (*.sxw), which was used by OpenOffice.org version 1.x and older StarOffice versions. To a lesser extent, odt2txt may be useful to extract content from OpenDocument spreadsheets (*.ods) and OpenDocument presentations (*.odp).

AutoComplete is a library allowing you to add IDE-like auto-completion (aka "code completion" or "Intellisense") to any Swing JTextComponent. Special integration is added for RSyntaxTextArea, since this feature is commonly needed when editing source code. Features include: Drop-down completion choice list. Optional companion "description" window, complete with full HTML support and navigable with hyperlinks. Optional parameter completion assistance for functions and methods, ala Eclipse and NetBeans. Completion information is typically specified in an XML file, but can even be dynamic.

utf8proc is a small C library that provides Unicode normalization, case-folding, and other operations for data in the UTF-8 encoding.

pfff is a tool for calculating a compact digital fingerprint of a file by sampling randomly from the file instead of reading it in full. Consequently, the computation has a flat performance characteristic, correlated with data variation rather than file size. pfff can be as reliable as existing hashing techniques, with provably negligible risk of collisions.

Vale is a fully extensible linter that focuses on your own writing style by making use of rules in individual YAML files. It is syntax-aware on markup languages such as HTML, Markdown, Asciidoc, and reStructuredText. The community around it also has a list of style guides implemented with Vale in their styles repo.

aha (Ansi Html Adapter) converts ANSI escape sequences of a Unix terminal to HTML code.

This package provides some tools to parse human-readable date/time text in Python.

This module provides a monotonic() function which returns the value (in fractional seconds) of a clock which never goes backwards.

tz helps you schedule things across time zones. It is an interactive TUI program that displays time across a few time zones of your choosing.

This library provides a timezone database for Python.

This is a python package for looking up the corresponding timezone for given coordinates on earth entirely offline.

This module parses the most common forms of ISO 8601 date strings (e.g. 2007-01-14T20:34:22+00:00) into datetime objects.

The package ciso8601 converts ISO 8601 or RFC 3339 date time strings into Python datetime objects.

rdate connects to an RFC 868 time server over a TCP/IP network, printing the returned time and/or setting the system clock.

Tzlocal returns a tzinfo object with the local timezone information. This module attempts to fix a glaring hole in pytz, that there is no way to get the local timezone information, unless you know the zoneinfo name, and under several distributions that's hard or impossible to figure out.

The dateutil module provides powerful extensions to the standard datetime module, available in Python 2.3+.

This package aims to make the transition away from pytz easier. It is intended for temporary usage only, and should allow you to drop your dependency on pytz while also giving your users notice that eventually you will remove support for the pytz-specific interface.

Termdown provides a fancy text display while it counts down to zero from a starting point you provide. The user can pause and resume the countdown from the text user interface. It can also be used in stop watch mode which counts forward or for just showing the current time.

This small Python module parses various kinds of time expressions.

This package provides a thin Python wrapper around tzdata.

The strict_rfc3339 Python module provides strict, simple, lightweight RFC3339 (Date and Time on the Internet: Timestamps) procedures.

It enables or aims to:

• Convert UNIX timestamps to and from RFC3339.

• Produce RFC3339 strings with a UTC offset (Z) or with the offset that the C time module reports is the local timezone offset.

• Be simple with minimal dependencies/libraries.

• Avoid timezones as much as possible.

• Be very strict and follow RFC3339.
