This page gives an in-depth specification of the DomTool language. Most members would probably prefer the more informal presentation in DomTool/UserGuide.

1. Source code

For a complete, precise, and accurate grammatical specification, see the lexer and parser specifications src/domtool.lex and src/domtool.grm in the DomTool source code. See src/tycheck.sml for the type-checker implementation. ["DomTool/Building"] has information on obtaining the source.

2. Token conventions

In the grammars that follow, we use these lexical token class names:

3. Predicates

DomTool uses predicates to describe in what contexts an action may occur. For instance, web-related actions should only occur inside the scope of a virtual host directive. Predicates are built up following the grammar in the table below, using the letter P as the non-terminal for predicates.

Meanings are given as statements that must hold about the context where an action is found. The context is represented as a stack of context IDs which have been declared with context declarations.
