The package ltxnew provides \new, \renew and \provide prefixes for checking definitions. It is designed to work with e-TeX distributions of LaTeX and relies on the LaTeX internal macro \@ifdefinable. Local allocation of counters, dimensions, skips, muskips, boxes, tokens and marks are provided by the etex package. \new and \renew as well as \provide may be used for all kind of control sequences.

ElegantNote is designed for writing working papers, especially for economics students. This template is based on the standard LaTeX article class. The goal of this template is to make the writing process easier and more comfortable.

This is an article, in French, based on a presentation made in Dunkerque for the Stage LaTeX on 12 June 2019. The article gives three examples of code in expl3 with (lots of) comments: Knuth's algorithm to create a list of primes, the sieve of Eratosthenes, Kaprekar sequences. The package contains the code itself, the documentation as a PDF file, and all the files needed to produce it.

This package provides EAN-8 and EAN-13 forms.

This package provides LaTeX, pdfLaTeX, XeLaTeX and LuaLaTeX support for the PoiretOne family of fonts, designed by Denis Masharov. PoiretOne is a decorative geometric grotesque with a hint of Art Deco and constructivism. There is currently just a regular weight and an artificially emboldened bold.

The package is a LaTeX package for ducks to be used in TikZ pictures.

The package chemstyle provides an extensible system for formatting chemistry documents according to the conventions of a number of leading journals. It also provides some handy chemistry-related macros.

The package provides a set of macros based on PSTricks to draw medical pedigrees according to the recommendations for standardized human pedigree nomenclature. The drawing commands place the symbols on a pspicture canvas. An interface for making trees is also provided. The package may be used both with LaTeX and PlainTeX. A separate Perl program for generating TeX files from spreadsheets is available.

Package TIPA uses the T3 encoding for producing IPA characters. The package is widely used in the field of linguistics, but because of the old encoding, the output documents are less productive than Unicode-based documents. This package redefines most of the TIPA-commands for outputting Unicode characters. Users can now use their beloved TIPA shortcuts with the benefits of Unicode, i.e., searchability, copy-pasting, changing the font and many more.

As this package needs the fontspec package for loading an IPA font, it needs to be compiled with XeLaTeX or LuaLaTeX. This package can also be viewed as an ASCII-based input method for producing IPA characters in Unicode. It needs the New Computer Modern font for printing IPA characters.

This package provides a collection of experimental programs and developments based on, or complementary to, the matter in his distribution directories.

This package can be used to include every kind of Scratch program in LaTeX documents. This may be particularly useful for Math Teachers and IT specialists.

This package provides commands for creating abstract argumentation frameworks via TikZ.

This package provides an English translation of the documentation for the wrapstuff package.

Mathtools provides a series of packages designed to enhance the appearance of documents containing a lot of mathematics. It is based on amsmath and fixes various deficiencies of it and standard LaTeX. It provides:

• Extensible symbols, such as brackets, arrows, harpoons, etc.;

• Various symbols such as \coloneqq (:=);

• Easy creation of new tag forms;

• Showing equation numbers only for referenced equations;

• Extensible arrows, harpoons and hookarrows;

• Starred versions of the matrix environments for specifying the column alignment;

• More building blocks: multlined, cases-like environments, new gathered environments;

• Maths versions of \makebox, \llap, \rlap etc.;

• Cramped math styles; and more...

The package suppresses fi and fl (and other ligatures) in Serbian text written using Roman script.

This package (ab)uses the inline enumeration capabilities of enumitem to add a displayed enumeration mode, triggered by adding gathered to the key-value option list of the enumerate environment. The end result is similar to a regular enumerate environment wrapped in a multicols environment, with the following advantages:

• it can pack items depending on their actual width rather than a fixed, constant number per line;

• it fills items in a line-major order (instead of column-major order).

The longfigure package uses and relabels components of the well-known longtable package to provide a table-like environment that can display a stream of figures as a single figure that can break across pages.

The package facilitates the use of stealth prefixes for counter names in order to help distinguish between counters from multiple input files. The package also provides a means to generate random counters and save such counter values for future typesetting.

This package defines several useful environments for a beautiful printable semester plan. It includes a timetable (which is using the schedule-Package) as well as appointments, deadlines, and exams.

This package provides a LaTeX package for students of Tsinghua University to write coursework more efficiently. It can also be used by students from other universities.

This LaTeX package gives meaning to various Unicode space characters.

This package provides font encodings, metrics and Lua script fragments for generating font support packages for 8-bit engines with l3build. An optional template-based system enables the automatic generation of font tables and l3build tests. It also eases addition of variable scaling to .fd files (unsupported by some tools).

It is primarily designed for fontinst, but can be adapted for use with other programs. Default configuration is intended to be cross-platform and require only tools included in TeX Live, but the documentation includes a simple adaption for integration with FontForge and GNU make.

With pxpic you draw pictures pixel by pixel. It was inspired by a lovely post by Paulo Cereda, among other things (most notably a beautiful duck) showcasing the use of characters from the Mario video games by Nintendo in LaTeX.

The style is designed for use with the musuos class, but it should be usable with other classes, too.
