| 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''' || || `Symbol` || Identifier starting with a lowercase letter || || `CSymbol` || Identifier starting with a capital letter || = 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` || = Types = Types describe expressions. As is standard in statically-typed programming languages, they are used only for validation purposes and have no real effect on the "output" of a program. The following table gives the grammar of types `T`. The section on expressions will give the meanings of types in terms of which expressions have which types. || '''Syntax''' || '''Description''' || || `Symbol` || Extern type || || `[T]` || List of `T`s || || `T1 -> T2` || Function from `T1` to `T2` || || `[P]` || Action allowed only when `P` is satisified; requires no environment variables on input and writes none of its own || || `[P] {CSymbol1 : T1, ..., CSymbolN : TN}` || Action that requires environment variables `CSymbol1`, ..., `CSymbolN` to have the given types when run || || `[P] {CSymbol1_1 : T1_1, ..., CSymbol1_N : T1_N} => {CSymbol2_1 : T2_1, ..., CSymbol2_M : T2_M}` || Like the last case, but the second set of typed environment variables describes what the action will write || || `P => T` || A nested action that requires that its nested configuration satisfy `P`; `T` should be some action type || || `(T)` || Grouping || |
