This package draws atomic s, p and d orbitals, as well as molecular orbital diagrams.

The Bembo-like font family, ETbb, expands ET-Bembo features to include a full set of figure styles, small caps in all styles, superior letters and figures, inferior figures, a new capital Sharp S with small caps version, along with macros to activate these features in LaTeX.

The package provides a LISP interpreter written using TeX macros; it is provided as a LaTeX package. The interpreter static scoping, dynamic typing, and eager evaluation.

This package provides basic utility programs, comprising: dvitype, which converts a TeX output (DVI) file to a plain text file; pooltype, which converts a TeX-suite program's pool (string) file into human-readable form; tftopl and pltotf, which convert TeX Font Metric (TFM) file to human readable Property List (PL) files and vice versa.

Typeset good-looking set notation as well as similar things such as Dirac braket notation, conditional probabilities, etc. The package is at least inspired by braket.

The package supports typesetting hacm, the alphabet of the constructed language Arka. The bundle provides nine official fonts, in Adobe Type 1 format.

Many languages --- like German or French --- use masculine and feminine grammatical genders. There are many ideas how to promote gender neutrality in those languages. The gender package uses alternately masculine and feminine forms. It is also possible to use just one form out of a template.

This package generates a calendar included events provided as .events files.

This package provides fancy cross-referencing support, based on the package's reference commands (\fref and \Fref) that recognise what sort of object is being referenced.

The current version does special formatting for the first line of text in a paragraph. The package is part of a larger body of tools which remain in preparation.

The style is intended to have enough features to draw any extensive game with relative ease. The facilities of PSTricks are used for graphics.

This package provides a class and a bibliography style for the FCAV-UNESP Brazilian university, written based on the institution rules for thesis publications.

This package collects together examples that have been posted to the PSTricks mailing list, together with many additional features for the basic pstricks, pst-plot and pst-node, including: bugfixes; new options for the pspicture environment; arrows; braces as node connection/linestyle; extended axes for plots (e.g., logarithm axes); polar plots; plotting tangent lines of curves or functions; solving and printing differential equations; box plots; matrix plots; and pie charts.

Writing a TeX length with \the writes the value and the unit without a space. Package isopt provides a macro \ISO which inserts a user defined space between number and unit.

This bundle contains three AMS classes: amsart (for writing articles for the AMS), amsbook (for books) and amsproc (for proceedings), together with some supporting material. The material is made available as part of the AMS-LaTeX distribution.

This is a simple TSV (tab-separated values) reader for LuaLaTeX and plain LuaTeX. It also supports (non-quoted) comma-separated values, or indeed values separated by any character.

The package allows you to enter Python code within a LaTeX document, execute the code, and access its output in the original document. There is also support for Bash, JavaScript, Julia, Octave, Perl, R, Raku (Perl 6), Ruby, Rust, and SageMath. Code is only executed when it has been modified, or when it meets user-specified criteria. Code may be divided into user-defined sessions, which automatically run in parallel. Errors and warnings are synchronized with the LaTeX document, so that they refer to the document's line numbers. External dependencies can be tracked, so that code is re-executed when the data it depends on is modified. PythonTeX also provides syntax highlighting for code in LaTeX documents via the Pygments syntax highlighter.

The package also provides a depythontex utility. This creates a copy of the document in which all Python code has been replaced by its output. This is useful for journal submissions, sharing documents, and conversion to other formats.

Using this package, \nolbreaks{some text} to prevent line breaks in some text. This has the advantage over \mbox that glue (rubber space) remains flexible. Most common cases are handled here (\linebreak is disabled, for example) but spaces hidden in macros or { and } can still create break-points.

The package checks references in a document, looking for numbered but unlabelled equations, for labels which are not used in the text, for unused bibliography references. It can also display label names in text near corresponding numbers of equations and/or bibliography references.

The package provides a consistent way of producing references throughout a project. Enough flexibility is provided to make local changes to a single reference. The user can configure their own setup. The package offers a direct interface to varioref (for use, for example, in large projects such as a series of books, or a multivolume thesis written as a series of documents), and name references from the nameref package may be incorporated with ease. For large projects such as a series of books or a multi volume thesis, written as freestanding documents, a facility is provided to interface to the xr package for external document references.

The package provides a command \telprint for formatting German telephone numbers.

This package, which works both for Plain TeX and for LaTeX, defines the \ifPDFTeX, \ifXeTeX, and \ifLuaTeX conditionals for testing which engine is being used for typesetting. The package also provides the \RequirePDFTeX, \RequireXeTeX, and \RequireLuaTeX commands which throw an error if pdfTeX, XeTeX or LuaTeX (respectively) is not the engine in use.

This package breaks with some of LaTeX's principles and redefines basic LaTeX commands with the aim of producing well-designed and clearly structured handouts: a sans-serif font is used by default; sections are not numbered, but highlighted by underlining; head- and footline display document information; and in order to avoid too much whitespace around the text the margin sizes are adjusted to smaller values. All in all, fancyhandout provides a means of typesetting documents not exclusively consisting of running text in a beautiful way.

The package provides BibLaTeX support for citations in the format specified by the MLA handbook.
