Replace implicit streams with explicit streams.
Shorten lines longer than 79 chars.
In some places, simplify some code, often using constructs such as
string.format that either did not exist or were too expensive to use
when the original code was written.
In some places, change predicate names that were not meaningful
without module qualification by *including* the module qualification
in the name (e.g. init -> browser_info_init).
In some places, add XXXs.
In browser_info.m, make the output stream *part* of the debugger type,
because without this, having the debugger type belong to the stream
typeclass does NOT make sense. (The typeclass instance for debugger
used to always write to the current output stream, which this diff
is replacing with the use of explicitly specified streams.)
In browse.m, consistently put stream arguments before other arguments.
In browse.m, when exporting Mercury predicates to C, export them
under names with the standard ML_BROWSE_ prefix, NOT under the name
of a *different* predicate with that prefix.
In diff.m, eliminate an unnecessary difference between what we print
when the difference between two terms is at the root, vs what we print
when the difference between two terms is lower down.
In interactive_query.m, when trying to write a program out to a file,
do NOT write the program to the current output stream if we cannot open
the file, since that would accomplish nothing useful.
Also in interactive_query.m, cleanup .dylib instead of .so on MacOS.
In util.m, delete some unused predicates.
In collect_lib.m, document why some code is not worth updating.
In declarative_oracle.m, rename predicates with previously-ambiguous
names.

In most modules, either the order of the declarations or the order

In some modules, neither made sense, so I changed *both* to an order

Since this code is in Prolog, I cannot be sure that I changed all the
places that should be changed, but that does not matter much.
Since Morphine was designed to work with the Prolog dialects of 1999,
had its last update in 2002, and we never test it, it is very likely
that it hasn't worked in a long time. We keep it around because
(a) it may interest someone, and (b) it doesn't require significant
maintenance. The fact that it does not run may be regrettable, but
it is not actually regretted by many would-be users, or (even) any at all.
(I actually noticed and fixed a bug while doing the above change:
it was a typo in a function symbol name.)

Implement the following improvements:
- Pass mdb variable bindings to the interactive query processor,
allowing queries to make use of live values.
- Catch exceptions thrown by queries, rather than crashing mdb.
- Write outputs using io.write_cc/3.
- Don't output underscore variables, avoiding spurious warnings.
- More protection of the user's namespace.
- Updated the cleanup code.
browser/interactive_query.m:
The interface now accepts corresponding lists of names and values,
which are matched up with variables occurring in the queries.
Replace the code generator with one that supports passing data
to and from the query, and catching exceptions from the query.
Pass the appropriate data at the time the query predicate is called.
Distinguish between failure of the query and failure of the dynamic
casts used to instantiate the query inputs.
Use module qualifiers to avoid clashing with user imports. (Should the
generated code use use_module, just in case?)
Perform I/O, failure handling and exception handling in the caller
instead of in the generated code. This is faster, more maintainable,
and means that errors are caught earlier.
Place source_file and line directives more carefully so as to ensure
more consistent error messages, and to help distinguish errors in the
template from errors in the query.
Factor out the query command parser to avoid double maintenance.

Add two new capabilities to the debugger.
The first capability is the idea of "held variables", variables that the
debugger holds onto even when execution has left the event they came from.
You can hold onto a variable via the mdb command "hold varname heldvarname".
You can suffix the name of the existing variable with a term path, in which
case the new held variable will refer only to the specified part of the term.
Later mdb commands can refer to the held variable by prefixing its name with
a dollar sign. For example, after "hold HeadVar__1^2 x", "$x" will refer to
the term that was the second argument of HeadVar__1 at the program point
at which the "hold" command was executed.
The second capability is the ability to compute the diff of two terms and
express those diffs as the term paths of the function symbols at which the two
terms differ, instead of the line numbers you get by using save_to_file and the
usual Unix diff command. The mdb command is "diff var1 var2". We limit the
number of term paths of difference sites that we display at any one time;
the mdb diff command has options to control this.
NEWS:
Mention the new capabilities.
doc/user_guide.texi:
Document the new mdb commands "hold" and "diff", the new mdb command

Recently I changed the interactive query facility in the debugger
to use `mmc --make' to build the shared library containing the query.

Various fixes to get the GCC back-end interface to bootstrap.
library/exception.m:
Define function versions of mercury__exception__builtin_catch_3_p_*.

compiler/stack_layout.m:
Add #includes for header files needed by these modules.
browser/dl.m:
Delete an unnecessary nested extern declaration, to avoid
a warning from `gcc -Wshadow'.
compiler/mlds_to_gcc.m:
When calling mlds_to_c to process foreign_code, make all
definitions public, so that the can be used from the assembler
code that we generate in mlds_to_gcc.
Don't call mlds_to_c to generate `.c' and `.h' files if the
module contains only `pragma foreign_decls', not `pragma
foreign_code', `pragma foreign_proc', or `pragma export'.
This change is needed to avoid calling mlds_to_c when
intermodule optimization is enabled and `pragma c_header_code'
declarations have been read in from the `.opt' file and have
propagated through to the MLDS. Calling mlds_to_c when the
module itself doesn't contain C code breaks things, since
Mmake won't compile and link in the generated `.c' files, but
those files contain the definition of the `*__init_type_tables()'
functions that are referenced by `*_init.c'.
XXX This is not quite right, since if the module itself contains
`pragma foreign_decls', the `.h' file might be needed.
But the Mercury standard library needs intermodule optimization
enabled for `make install' to work.
A better fix would be to ignore foreign_decls that were defined
in other modules, but to call mlds_to_c for foreign_decls
that were defined in the module that we're compiling.
compiler/modules.m:
Change the code which decides when to link in extra object files
for foreign code to reflect the above change to when mlds_to_gcc.m
invokes mlds_to_c.m.
compiler/mlds_to_c.m:
When target=asm, i.e. we're compiling to asm, but mlds_to_c.m
has been invoked to generate C code for a `foreign_code',
`foreign_proc', or `pragma export' declaration, don't generate
#include directives for the imported modules, since we may not
have generated any header file for them.
XXX This is a bit of a hack; it might sometimes lead to
problems, since the header files might sometimes be needed.
But including them unconditionally is definitely wrong,
since they may not exist, and so this change is needed to get
the compiler to bootstrap.
compiler/Mmakefile:
Add a dependency of mercury_compile on $(GCC_BACK_END_LIBS),
so that we know to relink it if the GCC back-end has changed.
(That variable is set to empty if we're not linking in the GCC
back-end, so it won't cause problems when not using the GCC
back-end.)

Also add `--make-opts' option, for passing options to `make'.
Put `-k' in `--make-opts', not `--mmake-opts', since `-k' is
an option to `make', not to `mmake'. This makes a difference
since although `make' options can be passed to `mmake', any
options after the first `make' option are assumed to be
options to `make', not to `mmake'.

Change `:- import_module' declarations to
`:- include_module' declarations.
browser/Mmakefile:
Remove the special case rule for `mer_browser.init' --
it doesn't work when the file names are not the same
as the module name. Instead, the default rule for `mdb.init'
is used and the output is copied to `mer_browser.init'.
browser/.cvsignore:
Rename header files, etc.
browser/*.m:
Add a `mdb__' prefix to the names of modules in the browser library
in `:- module' and `:- import_module' declarations.
trace/*.c:
Rename the header files for the browser library in
`#include' statements.
tests/hard_coded/Mmakefile:
tests/hard_coded/parse.m:
tests/hard_coded/parse.exp:
Test case.

If calling from the internal debugger, use readline input for the
interactive term browser and interactive queries.
browser/browse.m:
Change some if-then-elses to switches, which will help
catch errors if a new functor is added to the debugger type.
browser/parse.m:
browser/util.m:
Return a string from util__trace_getline/4 rather than a
list of chars, which saves converting from a string to a list
of chars and then back again.
browser/util.m:
Add a version of util__trace_getline that also takes I/O
stream arguments. Pass these arguments to MR_trace_getline.
browser/declarative_oracle.m:
Call util__trace_getline/4 to do input via readline (if
available). Improve error handling.
browser/interactive_query.m:
Call util__trace_getline to get user input, instead of
standard library predicates.
runtime/mercury_init.h:
runtime/mercury_wrapper.c:
runtime/mercury_wrapper.h:
trace/mercury_trace_internal.c:
trace/mercury_trace_internal.h:
Add two I/O stream arguments to MR_trace_getline.

This change allows interactive queries to be typed from the external debugger.
browser/debugger_interface.m:
Define new debugger requests: query/1, cc_query/1, io_query/1 and
mmc_options/1.
Define 2 new procedures that are used in trace/mercury_trace_external.c:
get_list_modules_to_import/3 retrieves from a *query/1 request a list
of modules to be imported; and get_mmc_options/2 retrieves from a
mmc_options/1 request the option to pass to mmc to compile the query.
browser/interactive_query.m:
Define a new procedure query_external/7 that does the same job as
query/7 but for the external debugger.
Unset the environment variable `MERCURY_OPTIONS' before compiling a
query; `MERCURY_OPTIONS' is exported before executing a program under
the control of Opium-M (and mdb) and is not supposed to be set before
compiling a program.
trace/mercury_trace_browse.ch:
Add a new function MR_trace_query_external() to interface the
ML_query_external() function defined by browser/interfactive_query.m.
trace/mercury_trace_external.c:
Add code to implement new commands `query', `cc_query', `io_query',
and `mmc_options', using the MR_trace_query_external() function defined
by trace/mercury_trace_browse.h.
trace/mercury_trace_external.h:
Export MR_debugger_socket_in and MR_debugger_socket_out since there
are needed in interactive_query.m.
doc/user_guide.texi:
Add a comment to tell that there exists duplicated documentation betwenn
Opium-M/source/interactive_queries.op and doc/user_guide.texi and to
tell me to update it if someone update the documentation here.
Estimated hours taken: 3
Add some test cases to test interactive queries.
tests/debugger/queens.inp:
Add tests of interactive queries.
tests/debugger/Mmakefile:
Add dependency of queens.out on queens.ints.
This is needed in order for us to use interactive queries.
tests/debugger/queens.m:
Export qperm/2, for use in interactive queries.
browser/interactive_query.m:
Flush MDB_stdout after printing the prompt, so things work
properly with I/O redirections.
trace/mercury_trace_internal.c:
Fix an off-by-one error detected by the above test cases.
Estimated hours taken: 17
Add support for invoking interactive queries to mdb.
browser/interactive_query.m:
New module, to implement interactive queries.
browser/dl.m:
browser/name_mangle.m:
Copy these files from extras/dynamic_linking, since
they are needed by browser/interactive_query.m.
configure.in:
runtime/mercury_conf.h.in:
Autodetect the presence of support for dlopen() etc.
browser/dl.m:
Add #ifdefs so that the code will compile (but report
an error at runtime) if dlopen() etc. are not supported.
browser/browser_library.m:
Add interface_query, dl, and name_mangle to the list of
modules in this library.
trace/mercury_trace_browse.h:
trace/mercury_trace_browse.c:
Add a new function MR_trace_query() to interface to the ML_query()
function defined by browser/interfactive_query.m.
trace/mercury_trace_internal.c:
Add code to implement new commands `query', `cc_query', `io_query',
and `mmc_options', using the MR_trace_query() function defined by
trace/mercury_trace_browse.h.
runtime/mercury_grade.h:
Add code to define MR_GRADE_OPT, so that browser/interactive_query.m
can use this to invoke mmc with the same grade that the executable
being debugged was built with.
doc/mdb_categories:
doc/user_guide.texi:
Document the new commands `query', `cc_query', `io_query',
and `mmc_options'.
