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.

RSyntaxTextArea is a syntax highlighting, code folding text component for Java Swing. It extends JTextComponent so it integrates completely with the standard javax.swing.text package. It is fast and efficient, and can be used in any application that needs to edit or view source code.

cobib is a command-line based bibliography management tool. It uses a plain-text database, a location-independent library, and features git integration, command-line support, and a curses-based TUI.

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

This package provides the tldr command allowing users to view tldr pages from a shell. The tldr pages are a community effort to simplify the man pages with practical examples described in https://tldr.sh/.

This package provides converters for various bibliography formats (e.g. Bibtex, RIS, etc.) using a common XML intermediate.

ack is a tool for finding text inside files. It is designed for hackers and programmers by being fast, ignoring VCS directories, letting a user easily specify file types, match highlighting, Perl-Compatible Regular Expressions, and being faster to type than grep.

Libconfig is a simple library for manipulating structured configuration files. This file format is more compact and more readable than XML. And unlike XML, it is type-aware, so it is not necessary to do string parsing in application code.

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.

This package transforms JSON into discrete assignments to make it easier to use line-based tools such as grep to search for what you want and see the absolute "path" to it.

utf-8-lineseparator provides a tool to efficiently check text files for valid UTF-8 use and to report which line endings they use.

GoAWK is a POSIX-compatible version of AWK that also has a CSV mode for reading and writing CSV and TSV files.

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.

This package provides yq, a command-line YAML, JSON and XML processor. It uses jq-like syntax but works with YAML files as well as JSON, XML, properties, CSV and TSV.

The drm_tools package contains the following commands:

accudate

An extended version of the "date" program that has sub-second accuracy.

binformat

Format complex binary data into text.

binload

Load data into a binary file using simple commands from the input.

binorder

Sort, merge, search, retrieve or generate test data consisting of fixed size binary records.

binreplace

Find or find/replace in binary files.

binsplit

Split test data consisting of fixed size binary records into one or more output streams.

chardiff

Find changes between two files at the character level. Unlike "diff", it lists just the characters that differ, so if the 40,000th character is different only that one character will be shown, not the entire line.

columnadd

Add columns of integers, decimals, and/or times.

datasniffer

A utility for formatting binary data dumps.

dmath

Double precision interactive command line math calculator.

extract

Extract and emit data from text files based on character or token position.

execinput

A utility that reads from STDIN and executes each line as a command in a sub-process.

indexed_text

A utility for rapid retrieval of text by line numbers, in any order, from a text file.

mdump

Format binary data.

msgqueue

Create message queues and send/receive messages.

mbin

dtmbout

Multiple buffer in and out. Used for buffering a lot of data between a slow device and a fast device. Mostly for buffering streaming tape drives for use with slower network connections, so that streaming is maintained as much as possible to minimize wear on the tape device.

pockmark

Corrupt data streams - useful for testing error correction and data recovery.

tarsieve

Filter, list, or split a tar file.

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.

Countdown 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.

This library brings the Olson tz database into Python. It allows accurate and cross platform timezone calculations using Python 2.4 or higher. It also solves the issue of ambiguous times at the end of daylight saving time. Almost all of the Olson timezones are supported.

Time is a command that displays information about the resources that a program uses. The display output of the program can be customized or saved to a file.

This library provides a timezone database for Python.

This small Python module parses various kinds of time expressions.

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

The main purpose of this package is to provide more complex arithmetic operations on dates/times. Heavy use is made of the relativedelta type from the dateutil library. Much of this package is just a light wrapper on top of this with some added features such as range generation and business day calculation.

This package provides a thin Python wrapper around tzdata.
