January 2000 See the building guide. The GHC documentation is written using DocBook 3.1, so the DTD line should be: <!DOCTYPE Article PUBLIC "-//OASIS//DTD DocBook V3.1//EN"> This guide is not meant to teach you how to write DocBook; read the DocBook book for that. It is more of a reference than a tutorial, so see the DocBook home page for other links. The rest of this section outlines the use of several tags which may not be obvious (DocBook is rather scholastic in style: it has tags for many things from C function prototypes to keyboard bindings; at the same time it has many omissions and oddities). The current scheme has many infelicities, partly because it was dreamt up in a hurry while the author was learning DocBook and converting the documentation thereto, and partly because DocBook is rather C-centric. Command Used for commands typed into interactive sessions (e.g. cp foo bar and the names of programs such as gmake. Constant Used for system constants such as U_MAXINT and Makefile variables like SRC_FILES (because they are usually constant for a given run of make, and hence have a constant feel to them). Email For email addresses. This is a tag that's easy to overlook if you don't know it's there. Filename Used for paths, filenames, file extensions. Function Used for functions and constructors. IndexTerm The normal way to mark up an index term is <IndexTerm><Primary>term</Primary></IndexTerm>. KeyCapKeyCombo Some more tags you may miss. Used for combinations such as ControlD. Literal Used for everything that should appear in typewriter font that has no other obvious tag: types, monads, small snippets of program text that are formatted inline, and the like. Option Used for compiler options and similar. ProgramListing For displayed program listings (including shell scripts). Screen For displayed screen dumps, such as portions of shell interaction. It's easy to tell the difference between these and shell scripts: the latter lack a shell prompt. VarName Used for variables, but not type variables. Tables are quite complicated to write in SGML (as in HTML, there are lots of fiddly tags), so here's an example you can cannibalise. In the spirit of the LaTeX short introduction I don't repeat all the markup verbatim; you have to look at the source for that. Here's a sample table With differently aligned cells There's not much else to it. Entries can span both extra rows and extra columns; just be careful when using block markup (such as Paras) within an Entry that there is no space between the open and close Entry tags and the adjacent text, as otherwise you will suffer from Pernicious Mixed Content (the parser will think you're using inline markup).
