This package can generate documents with and without answers from a single file by toggling a switch. However, it can only be used to create documents to be printed on paper.

This is a collection of macros to draw histogram bars inside a LaTeX picture environment.

This package ports PEG (Parsing Expression Grammars) to TeX. Following the design in LPEG (Parsing Expression Grammars for Lua), it defines patterns as LaTeX3 variables, and offers several operators to compose patterns.

This package generates alphabet soup puzzles (aka word search puzzles), and variations using numbers or other symbols. It provides macros to generate an alphabet soup style puzzle (also known as word search puzzles or find-the-word puzzles). It also allows creating number soup and soups with custom symbol sets.

Sans serif maths (produced by the beamer class or the sfmath package) often has accents positioned incorrectly. This package fixes the positioning of such accents when the default font (cmssi) is used for sans serif maths.

This package extracts the letters of a command's name (e.g., foo for command \foo), in a reliable way.

This package provides a collection of fonts that reproduce those used in old German printing and handwriting. The set comprises Gothic, Schwabacher and Fraktur fonts, a pair of handwriting fonts, Sutterlin and Schwell, and a font containing decorative initials. In addition, there are two re-encoding packages for Haralambous's fonts, providing T1, using virtual fonts, and OT1 and T1, using Metafont.

Some publishers organize book series with subseries. In this case, two numbers are associated with one volume: the number inside the series and the number inside the subseries. This package provides new fields to manage such system.

This package provides primitives for drawing Business Process Modelling and Notation (BPMN) models. It includes tasks, subprocesses, events, task markers and gateways. The symbols aim to follow the BPMN standard as closely as possible.

This lightweight package provides the colorstrip environment, that places its contents into a full page width colour strip.

This module provides the french style that can be set using \DTMsetstyle provided by datetime2.sty.

The bundle offers macros and BibTeX styles for the American Economic Review (AER), the American Journal of Agricultural Economics (AJAE), the Canadian Journal of Economics (CJE), the European Review of Agricultural Economics (ERAE), the International Economic Review (IER) and Economica.

The macro sets are based on (and require) the harvard package, and all provide variations of author-date styles of presentation.

This package provides some LaTeX support for the use of EBGaramond12 in mathematics.

TeX's \let assignment does not work for LaTeX macros with optional arguments or for macros that are defined as robust macros by \DeclareRobustCommand. This package defines \LetLtxMacro that also takes care of the involved internal macros.

The package provides the language definition file for support of Esperanto in Babel. Some shortcuts are defined, as well as translations to Esperanto of standard LaTeX names.

This package defines a command \titleref that allows you to cross-reference section (and chapter, etc) titles and captions just like \ref and \pageref. The package does not interwork with hyperref; if you need hypertext capabilities, use nameref instead.

Product integrals are to products, as integrals are to sums. They have been around for more than a hundred years, they have not become part of the standard mathematician's toolbox, possibly because no-one invented the right mathematical symbol for them. The authors have remedied that situation by proposing the symbol and providing this font.

This package allows defining additional meta data within the PDF file which can be interpreted by the PDF presenter console (pdfpc) program.

The package provides a set of style files for use with BibLaTeX and Biber to produce citations and bibliographies in accordance with the widely-used Oxford Standard for the Citation of Legal Authorities. It also includes facilities for constructing tables of cases and legislation from citations (in conjunction with appropriate indexing packages).

This package provides a package which provides access to some interesting characters of the Text Companion fonts (TS1 encoding) in maths mode.

The bundle provides two packages: commado and filesdo. The package commado provides the command \DoWithCSL, which applies an existing one-parameter macro to each item in a list in which terms are separated by commas.

The package filesdo provides the command \DoWithBasesExts, which runs the single parameter command on each file whose base and extension are provided through two comma-separated lists.

These loop'-like commands are (themselves) entirely expandable.

TeX and LaTeX provide few facilities for dates by default, though many packages have filled this gap. This package fills it, as well, with a pure TeX-primitive implementation. It can print dates, advance them by numbers of days, weeks, or months, determine the weekday automatically, and print them in (mostly) arbitrary format. It can also print calendars (monthly and yearly) automatically, and can be easily localized for non-English languages.

The bundle provides three packages: printsudoku, which provides a command \sudoku whose argument is the name of a file containing a puzzle specification; solvesudoku, which attempts to find a solution to the puzzle in the file named in the argument; and createsudoku, which uses the random package to generate a puzzle according to a bunch of parameters that the user sets via macros.

The bundle comes with a set of ready-prepared puzzle files.

Diagxy is a general diagramming package, useful for diagrams in a number of mathematical disciplines.
