library/term.m:
library/term_context.m:
As above.
Rename the term.context type as term_context.term_context, with
term.context now being defined as an equivalence type.
Replace the context_init function and predicate and the dummy_context_init
function with just one function: dummy_context. This name includes
the important part (the fact that it return a *dummy* context) and deletes
the nonimportant part (dummy contexts are just about never updated,
so the function does not really "initialize" them).
Reduce function/predicate pairs that do the same thing to just a function.
library/MODULES_DOC:
library/library.m:
Add the new module to the list of standard library modules.
NEWS:
Mention the new module, and the obsoleting of the moved predicates
and functions in term.m.
compiler/*.m:
library/*.m:
Conform to the changes above.

% File: write_module_interface_files.m.
|
|
% Main author: fjh (when this code was in modules.m).
|
|
%
|
|
% This module writes the automatically generated .int3, .int2 and .int files
|
|
% (and if needed, the .int0 file) for each Mercury source module.
|
|
%
|
|
% The interface file system works as follows:
|
|
%
|
|
% 1. a .int3 file is written, which contains all the types, typeclasses, insts
|
|
% and modes defined in the interface. Equivalence types, solver types, insts
|
|
% and modes are written in full, others are written in abstract form. These
|
|
% are module qualified as far as possible given the information present in the
|
|
% current module.
|
|
%
|
|
% 2. The .int and .int2 files are created, using the .int3 files
|
|
% of imported modules to fully module qualify all items.
|
|
% The .int2 file is mostly just a fully qualified version of the .int3 file,
|
|
% however it also includes some extra information, such as functors for
|
|
% discriminated union types, which may be needed for mode analysis.
|
|
%
|
|
% 3. The .int0 file is similar to the .int file except that it also
|
|
% includes declarations (but not clauses) from the implementation section.
|
|
% It is generated only for modules that have submodules.
|
|
%
|
|
% NOTE The above is only a summary, and may be out of date. An attempt
|
|
% at an up-to-date and much more detailed description can be found in
|
|
% notes/interface_files.html.
