This document was automatically generated by the {\em BNF-Converter}. It was generated together with the lexer, the parser, and the abstract syntax module, which guarantees that the document matches with the implementation of the language (provided no hand-hacking has taken place).

|
||||
\section{The lexical structure of GF}
|
||||
\subsection{Identifiers}
|
||||
Identifiers \nonterminal{Ident} are unquoted strings beginning with a letter,
|
||||
followed by any combination of letters, digits, and the characters {\tt \_ '},
|
||||
reserved words excluded.
|
||||
|
||||
|
||||
\subsection{Literals}
|
||||
Integer literals \nonterminal{Int}\ are nonempty sequences of digits.
|
||||
|
||||
|
||||
String literals \nonterminal{String}\ have the form
|
||||
\terminal{"}$x$\terminal{"}, where $x$ is any sequence of any characters
|
||||
except \terminal{"}\ unless preceded by \verb6\6.
|
||||
|
||||
|
||||
Double-precision float literals \nonterminal{Double}\ have the structure
|
||||
indicated by the regular expression $\nonterminal{digit}+ \mbox{{\it `.'}} \nonterminal{digit}+ (\mbox{{\it `e'}} \mbox{{\it `-'}}? \nonterminal{digit}+)?$ i.e.\
|
||||
two sequences of digits separated by a decimal point, optionally
|
||||
followed by an unsigned or negative exponent.
|
||||
|
||||
|
||||
|
||||
|
||||
\subsection{Reserved words and symbols}
|
||||
The set of reserved words is the set of terminals appearing in the grammar. Those reserved words that consist of non-letter characters are called symbols, and they are treated in a different way from those that are similar to identifiers. The lexer follows rules familiar from languages like Haskell, C, and Java, including longest match and spacing conventions.
|
||||
|
||||
The reserved words used in GF are the following: \\
|
||||
|
||||
\begin{tabular}{lll}
|
||||
{\reserved{PType}} &{\reserved{Str}} &{\reserved{Strs}} \\
|
||||
{\reserved{Type}} &{\reserved{abstract}} &{\reserved{case}} \\
|
||||
{\reserved{cat}} &{\reserved{concrete}} &{\reserved{data}} \\
|
||||
{\reserved{def}} &{\reserved{flags}} &{\reserved{fun}} \\
|
||||
{\reserved{in}} &{\reserved{incomplete}} &{\reserved{instance}} \\
|
||||
{\reserved{interface}} &{\reserved{let}} &{\reserved{lin}} \\
|
||||
{\reserved{lincat}} &{\reserved{lindef}} &{\reserved{of}} \\
|
||||
{\reserved{open}} &{\reserved{oper}} &{\reserved{param}} \\
|
||||
{\reserved{pre}} &{\reserved{printname}} &{\reserved{resource}} \\
|
||||
{\reserved{strs}} &{\reserved{table}} &{\reserved{transfer}} \\
|
||||
{\reserved{variants}} &{\reserved{where}} &{\reserved{with}} \\
|
||||
\end{tabular}\\
|
||||
|
||||
The symbols used in GF are the following: \\
|
||||
|
||||
\begin{tabular}{lll}
|
||||
{\symb{;}} &{\symb{{$=$}}} &{\symb{:}} \\
|
||||
{\symb{{$-$}{$>$}}} &{\symb{\{}} &{\symb{\}}} \\
|
||||
{\symb{**}} &{\symb{,}} &{\symb{(}} \\
|
||||
{\symb{)}} &{\symb{[}} &{\symb{]}} \\
|
||||
{\symb{{$-$}}} &{\symb{.}} &{\symb{{$|$}}} \\
|
||||
{\symb{?}} &{\symb{{$<$}}} &{\symb{{$>$}}} \\
|
||||
{\symb{@}} &{\symb{!}} &{\symb{*}} \\
|
||||
{\symb{{$+$}}} &{\symb{{$+$}{$+$}}} &{\symb{$\backslash$}} \\
|
||||
{\symb{{$=$}{$>$}}} &{\symb{\_}} &{\symb{\$}} \\
|
||||
{\symb{/}} & & \\
|
||||
\end{tabular}\\
|
||||
|
||||
\subsection{Comments}
|
||||
Single-line comments begin with {\symb{{$-$}{$-$}}}. \\Multiple-line comments are enclosed with {\symb{\{{$-$}}} and {\symb{{$-$}\}}}.
|
||||
|
||||
\section{The syntactic structure of GF}
|
||||
Non-terminals are enclosed between $\langle$ and $\rangle$.
|
||||
The symbols {\arrow} (production), {\delimit} (union)
|
||||
and {\emptyP} (empty rule) belong to the BNF notation.
|
||||
All other symbols are terminals.\\
