Concerning the abstract syntax tree and recording absolutely
everything about the source code in it; is this really
What SWI Prolog does to support its debugger is
- retain the source text in a file
- in the AST, record the beginning and length of each term.
For Erlang, 16#fc would be tokenised as
For a Prolog dialect converter I wrote, I adopted the rule
that % comments with a preceding token on the same line were
attached to the *preceding* term while % comments without
such a token were attached to the *following* term, with
%comments preceding a predicate attached to the following
predicate as a whole. Thus
% following predicate
foo(...) :- % foo(...)
bar(...), % also bar(...).
ugh(...). % ugh(...)
This seemed to fit user expectations pretty well.
