This LaTeX package provides an interface to define and evaluate key-based replacement rules. It can be used to parse the argument specification of a document command.

This package provides a drop-in replacement for the New Century Schoolbook font from Adobe's basic set.

SticksToo is a reworking of the STIX2 fonts with support files focussing on enhancements of support for LaTeX users wishing to be able to access more of its features. A companion addition to the newtxmath package provides a matching math package using STIX2 letters (Roman and Greek) with newtxmath symbols.

This package uses both tracklang and texosquery to look up the locale information from the operating system and provide commands that can access locale-dependent information, such as the currency symbol and decimal separator.

This is a set of 23 tiny packages designed to make it easier to use fonts from the initials package in LaTeX, e.g., with the lettrine package.

Domain coloring is a technique to visualize complex functions by assigning a color to each point of the complex plane. This package calculates with the help of Lua any complex function to visualize its behavior. The value of the complex function can be described by radius and angle which can be two values of the HSV-color model, which then defines the color of each point in the complex plane.

EncTeX is (another) TeX extension, written at the change-file level. It provides means of translating input on the way into TeX. It allows, for example, translation of multibyte sequences, such as utf-8 encoding.

The package provides basic arithmetic operations to 8 decimal places for plain TeX or LaTeX. Results are exact when they fit within the digit limits. Along with the basic package is an optional extension that adds computation of sin, cos, log, sqrt, exp, powers and angles. These are also exact when theoretically possible and are otherwise accurate to at least 7 decimal places. In addition, the package provides a stack-based programming environment.

The package is an unofficial alternative to the package provided with the Asymptote distribution, for including pictures within a LaTeX source file. While it does not duplicate all the features of the official package, this package is more user-friendly in several ways. Most notably, Asymptote errors are repackaged as LaTeX errors, making debugging less of a pain. It also has a more robust mechanism for identifying unchanged pictures that need not be recompiled.

The package provides a mechanism for inputting non-ASCII text. Nowadays, the job is mostly done by the inputenc package in the LaTeX distribution.

The package offers BibLaTeX support for citations in German legal texts.

MusiXTeX provides a set of macros, based on the earlier MusicTeX, for typesetting music with TeX. To produce optimal spacing, MusiXTeX is a three-pass system: etex, musixflx, and etex again. (Musixflx is a Lua script that is provided in the bundle.) The three-pass process, optionally followed by processing for printed output, is automated by the musixtex wrapper script.

The package uses its own specialised fonts, which must be available on the system for musixtex to run. The MusiXTeX macros are universally acknowledged to be challenging to use directly: the pmx preprocessor compiles a simpler input language to MusiXTeX macros.

This package supports the spelling of cardinal and ordinal numbers. Supported languages are English, French, German, Hungarian, Italian, and Latin.

Graphpaper is a LaTeX document class which allows printing several types of graph papers: bilinear (millimeter paper), semilogarithmic, bilogarithmic, polar, log-polar, Smith charts. It is based on the picture environment and its extensions.

The package provides special PGF/TikZ nodes for the text, marginpar, footer and header area of the current page. They are inspired by the current page node defined by PGF/TikZ itself.

Frederika2016 is an attempt to digitize Hermann Zapf's Frederika font. The font is the Greek companion of Virtuosa by the same designer. This font is a calligraphy font and this is an initial release.

kalendarium is a LaTeX3 package that provides several macros with which to print dates in classical Latin given days on the Julian or Gregorian calendars, using the same syntax used by ancient Roman authors. The format of these dates may be customised either in the package options or on a per-command basis; these options also allow for the generation of date strings according to different eras of the Classical period.

The Orkhun font covers an old Turkic script. It is provided as Metafont source.

This package provides a convenient and coherent way to deal with name of functional spaces (mainly Sobolev spaces) in functional analysis and PDE theory. It also provides a set of macros for dealing with norms, scalar products and convergence with some object oriented flavor (it gives the possibility to override the standard behavior of norms, ...).

This package provides a LaTeX class nanicolle.cls for typesetting collection labels and identification labels in Chinese style or in western style for plant herbarium specimens. So far, documents using this class can only be compiled with XeLaTeX.

This package provides font information needed to load the cmmi and cmmib fonts for use to produce old-style numbers.

This package provides a language support package for Omega and Lambda. This replaces the original Omega package for use with Lambda, and provides extra facilities (including Babel-like language switching, which eases porting of LaTeX documents to Lambda).

This is a PSTricks package which allows placing text over objects without obscuring background colors.

This package provides LaTeX, pdfLaTeX, XeLaTeX, and LuaLaTeX support for Coelecanth fonts, designed by Ben Whitmore. Coelacanth is inspired by the classic Centaur type design of Bruce Rogers, described by some as the most beautiful typeface ever designed. It aims to be a professional quality type family for general book typesetting.
