README for the xdoc and docindex packages. The standard LaTeX doc package is well-known to all LaTeX hackers. Without its support for the .dtx-file style of literate programming, the TeX world would probably be much more plagued by the horrors of poorly commented and mysterious code than it is today. The past good decade that doc has been with us has been -- good. But even the sun has spots; doc is an old package and, as old code often tends to do, it breaks if you try to bend it into doing something new. The xdoc package is (or rather is meant to be) a rewrite from scratch which both can take a lot more bending and is ready for LaTeX2e*. What exists so far is only xdoc2: the "second prototype" for the xdoc package. xdoc2 is not a complete rewrite of doc, but rather an add-on to doc which reimplements many of its mechanisms (more precisely those mechanisms which I think should be possible to "bend" into doing new things, but have found to be fixed to their present behaviour) and provides a few new features of its own. Even though xdoc2 is a prototype and some of the code in it is experimental, I consider it to be safe enough to build productive applications on, as I intend to keep xdoc2 available even after the final xdoc package is released. Among the features of xdoc2 are: - new commands for describing things (cf. \DescribeMacro) and a package/class writer's interface for defining new such commands. - new environments for defining things in (cf. the macro environment) and a package/class writer's interface for defining new such environments. - support for two-sided document designs. - support for external cross-referencing. - improved sorting of macros, with support for defining prefixes that should be ignored when sorting. - support for CVS-style version numbering. The other new features are of little interest to the mere user, but they may be ever so useful to those who are in the habit of hacking doc. Here we have for example: - basic commands implementing a robust "string" datatype. - an abstract command interface for making index entries; this would simplify supporting a different index sorting program. Besides xdoc2, there are also the docindex/docidx2e packages. These provide mechanisms for a more flexible formatting of the index and list of changes than is possible with the mechanisms for this in the doc package. In particular docindex/docidx2e provides for automatic collapsing of trivial index levels, something which often happens in automatically generated multilevel indices such as the list of changes. The reason there are two packages is that docindex is a LaTeX2e* package, whereas docidx2e is a "downgraded" variant which runs on a normal LaTeX2e installation. Both do however follow the same internal logic.

xdoc – Extending the LaTeX doc system
Xdoc is a project to rewrite the implementation of the LaTeX doc package (in a broader sense) to make its features more general and flexible. For example, where doc only provides commands for documenting macros and environments, xdoc also provides commands for similarly documenting package options and switches. This is furthermore done in such a way that it is very easy to add more such commands for documenting things, such as e.g., templates (an important concept in the future LaTeX3) and program components for other languages (functions, classes, procedures, etc.). A side effect is that many minor bugs in doc are fixed.The design aims to take advantage of many still experimental features of future versions of LaTeX, but since these are neither reasonably stable nor widely available, the configuration interfaces and package author commands of xdoc are likely to change. To still provide a stable interface for other packages to build upon, the actual package names include a "major version number" of sorts. The drop-in replacement package for standard doc is xdoc2; it requires nothing outside standard LaTeX2ε. The docindex/docidx2e package changes the index and list of changes typesetting so that none of the formatting has to be controlled via the index style file. The docindex package provides control of formatting via templates (nice interface, but requires several experimental packages), whereas the docidx2e package has traditional raw macro interfaces and works with standard LaTeX2ε.
