library/getopt.m:
library/getopt_io.m:
Fix bug where a negation option (--no-foo) would set the value of a
maybe_string option to maybe_int(no) instead of maybe_string(no)
in the option table.
In the Mercury standard library, every exported predicate or function
has (or at least *should* have) a comment that documents it, including
the meanings of its arguments. About 35-40% of these modules put `'s
(left and right quotes) around the names of the variable representing
those arguments. Some tried to do it consistently (though there were spots
with unquoted or half quoted names), while some did it only a few places.
This is inconsistent: we should either do it everywhere, or nowhere.
This diff makes it nowhere, because
- this is what the majority of the standard library modules do;
- this is what virtually all of the modules in the compiler, profiler,
deep_profiler etc directories do;
- typing all those quotes when adding new predicates in modules that
follow this convention is a pain in the ass; and because
- on many modern terminals, `' looks non-symmetrical and weird.
Likewise, the comment explaining a predicate often started with
% `predname(arguments)' returns ...
This diff deletes these quotes as well, since they add nothing useful.
This diff does leave in place quotes around code fragments, both terms
and goals, where this helps delineate the boundaries of that fragment.
library/getopt_io.m:
Split the work of the predicates that process command line argument lists
into three passes:
- The first pass separates option args from nonoption args, and record
which options the option args are set (and to what values, if relevant).
- The second, optional pass replaces mentions of file_special options
with the contents of the files they name, including any file_special
options in them, and so on.
- The third pass takes the final list of option values from which all
file_special options have been expanded, and uses them to update
the option table, applying any special option handlers as needed.
The point of this is that in several places in the compiler, we sometimes
want to make changes to the operation of just one of these passes, e.g.
by adding options from a Mercury.options file to an argument list.
Doing it the old way works, but it is hard to understand and to modify.
Add a check for an error we have not tried to detect before: when
a file named in a file_special option contains to an option list
that specifies, directly or indirectly, a file_special option for
that same file. Without the new check, the result would be an infinite
repetition of the same file_special expansion over and over again.
Use named types and insts for the frequently used higher order constructs
used by this module.
Add inst-preserving versions of cord operations that getopt*.m now need.
To avoid having to export the implementation type of cords from cord.m,
duplicate the type, and the few needed operations on it, here.

compiler/mercury_compile_main.m:
Conform to the change in handle_options.m.
... using an approach proposed by Peter, with an extra twist from Julien.
Instead of having two modules, getopt.m and getopt_io.m, with the former
defining predicates that do not take an I/O state pair, and the latter
defining predicates that do take an I/O state pair, put both kinds of
predicates into a single module. The versions with an I/O state pair
have an "_io" suffix added to their names for disambiguation.
Both versions are a veneer on top of a common infrastructure,
which relies on a simple type class to implement the operation
"give the contents of the file with this name". The predicate versions
with I/O state pairs have a normal implementation of this typeclass,
while the predicate versions that do not have I/O state pairs
have an implementation that always returns an error indication.
The above change just about doubles the number of exported predicates.
We already had two versions of most exported predicates that differed
in whether we returned errors in the form of a string, or in the form
of a structured representation, with names of the latter having
an "_se" suffix. Since we agreed that the structured representation
is the form we want to encourage, this diff deletes the string versions,
and deletes the "_se" suffix from the predicate names that used to have them.
(It still remains at the end of the name of a type.) This "undoubling"
should offset the effect of the doubling in the previous paragraph.
Eventually, we want to have just one module, getopt.m, containing
the updated code described above, but for now, we put the same code
into both getopt_io.m and getopt.m to prevent too big a shock to
people with existing code that uses getopt_io.m.

library/*.m:
As per the recent change to the coding standard, avoid module

Reformat declarations and descriptive comments to better utilise

The getopt and getopt_io modules use strings to describe errors that occur
during option processing. There are a couple of problems with doing this:
(1) it makes some assumptions about how client programs want to word, and to a
large extent, format these error messages.
(2) it assumes that the error messages are in English.
This diff changes the getopt and getopt_io modules to use structured
representations of errors instead of strings. This structured representation
is defined by the new option_error/1 type. We introduce new versions of the
various process_options predicates that are suffixed with "_se" (standing for
"structured error") that return values of type option_error/1 when an error occurs.
A new function, option_error_to_string/1, converts option_error/1 values into
the strings that the getopt and getopt_io modules previously generated. The
existing process_options predicates are just wrappers around all of this for
the purposes of backwards compatibility.
The new option_error/1 type returns more information than existing error
messages require, for example, where possible we return both the element of the
option enumeration involved and a string giving the option as it actually
appeared on the command line.

library/getopt_io.m:
Add this new module as an extended variant of getopt.m. The extension
is support for file_special options, which read the contents of a file
and act as the words in it had appeared on the command line. The
intention is to use this facility to replace most of the options with
which mmake currently invokes mmc in a workspace, whose clutter now
takes up about ten lines per invocation.
Since processing options may now involve accessing a file, the main
predicate process_options now needs a pair of I/O state arguments.
Since some places where one wants to process options do not have I/O
states, we want to retain the old interface of process_options as well.
Since it is not practical to parameterize a group of predicates to
work both in the presence and in the absence of I/O states, I added
the code in a new module. While most changes to option handling should
be done to both getopt.m and getopt_io.m, I expect such changes to be
few and far between, so I think overall the new module is the best
solution.

the nondet determinism dates from before the time the compiler
supported multi.
Add a version of process_options that allows it to be run more
than once (by allowing it to start with an option table returned
by a previous invocation) and returns the set of options set by
each invocation, so that the caller can tell which invocation
(if any) has set any given option.
Switch to 4-space indentation to reduce the number of bad line breaks.

Allow reconfiguration of existing installations, for example
to use a different C compiler. The reconfiguration works
by making a new copy of the scripts and mercury_conf.h,
and storing them in a partial installation directory tree
which uses the libraries and executables from the existing
installation.
Use this method to configure binary distributions, rather
than using a cut down version of the configuration script,
to avoid code duplication and to handle the case where the
C compiler in use on the installation machine is different
than that used to build the binary distribution.
This is more robust than the previous method of using a different
C compiler, which was to set the MERCURY_C_COMPILER variable and
hope the different C compilers were compatible enough.

Ralph Becket <rwab1@cam.sri.com>'s changes to add functions for
the remaining output det predicates in a number of modules in the
standard library. Basically, for each
:- pred f(in, ..., in, out) is det.
he has added the declaration
:- func f(in, ..., in) = out.
and definition
f(X1, ..., Xn) = Y :-
f(X1, ..., Xn, Y).
The changes were made using a mostly automatic process.

Undo Zoltan's bogus update of all the copyright dates.
The dates in the copyright header should reflect the years
in which the file was modified (and no, changes to the
copyright header itself don't count as modifications).

library/getopt.m:
Added a new kind of option: maybe_int, to allow optional
arguments with integer values. Also added
getopt__lookup_maybe_int_option/3 to look up options of
type maybe_int.
