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

[[TableOfContents()]]

= 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.

= Token conventions =

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

|| '''Name''' || '''Description''' ||
|| `CSymbol` || Capitalized identifier ||

= 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.

|| '''Syntax''' || '''Description''' || '''Meaning''' ||
|| `Root` || Root || The stack is empty. ||
|| `CSymbol` || Context ID || `CSymbol` is on the top of the stack. ||
|| `^P` || Suffixes || Some (not necessarily strict) suffix of the stack matches `P`. ||
|| `!P` || Not || The stack ''doesn't'' match `P`. ||
|| `P1 & P2` || And || The stack matches both `P1` and `P2`. ||
|| `(P)` || Grouping || Identical to `P` ||
