Library changes required to make the compiler work on Windows
without Cygwin. (Compiler changes to come separately).
library/dir.m:
Handle Windows-style paths.
Change the determinism of dir.basename and dir.split_name.
dir.basename now fails for root directories (a new function
dir.basename_det calls error/1 rather than failing).
dir.split_name fails for root directories or if the pathname
passed doesn't contain a directory separator.
Add predicates dir.make_directory, dir.path_name_is_absolute
and dir.path_name_is_root_directory.
Add a multi predicate dir.is_directory separator which
returns all separators for the platform (including '/' on
Windows), not just the standard one.
Add a function dir.parent_directory (returns "..").
Add dir.foldl2 and dir.recursive_foldl2, to iterate through
the entries in a directory (and maybe its subdirectories).
Change '/' to correctly handle Windows paths of the form
"C:"/"foo" and "\"/"foo".
Don't add repeated directory separators in '/'.
library/io.m:
Add io.file_type and io.check_file_accessibility.
Add predicates to deal with symlinks -- io.have_symlinks,
io.make_symlink and io.follow_symlink.
Add io.file_id for use by dir.foldl2 to detect
symlink loops. This is a bit low level, so it's
not included in the user documentation.
Add io.(binary_)input_stream_foldl2_io_maybe_stop, which
is like io.(binary_)input_stream_foldl2_io, but allows
stopping part of the way through. This is useful for
implementing `diff'-like functionality to replace
mercury_update_interface.
Use Windows-style paths when generating temporary file
names on Windows.
Add versions of the predicates to generate error messages
to handle Win32 errors.
Add versions of the predicates to generate error messages
which take a system error code, rather than looking up
errno. This simplifies things where the error we
are interested in was not from the last system call.
library/exception.m:
Add a predicate finally/6 which performs the same function
as the `finally' clause in languages such as C# and Java.
Add predicates try_det, try_io_det and try_store_det,
which only have one mode so they are more convenient
to pass to promise_only solution.
library/Mmakefile:
Add dependencies on runtime/mercury_conf.h for files which
use the MR_HAVE_* macros.
library/string.m:
Add a function version of string__index.
NEWS:
Document the new predicates and functions and the change
of determinism of dir.split_name and dir.basename.
configure.in:
runtime/mercury_conf.h.in:
Test for lstat, mkdir, symlink and readlink.
runtime/mercury_conf_param.h:
Add a macro MR_BROKEN_ST_INO, which is true if the st_ino
field of `struct stat' is garbage. Currently defined iff
MR_WIN32 is defined.
compiler/compile_target_code.m:
compiler/modules.m:
compiler/options_file.m:
compiler/prog_io.m:
compiler/source_file_map.m:
Changes required by the change of determinism of
dir.split_name and dir.basename.
tests/hard_coded/Mmakefile:
tests/hard_coded/dir_test.{m,exp,exp2}:
Test case.

compiler/*.m:
Import only one compiler module per line. Sort the blocks of imports.
This makes it easier to merge in changes.
In a couple of places, remove unnecessary imports.

Change the compiler and tools so that `.' and not `:' is now used as the
module separator in all output.
Infix `.' now has associativity yfx and priority 10.
NEWS:
Report the change.
configure.in:
Amend the test for an up-to-date Mercury compiler to check whether
it recognises `.' as a module qualifier.

Change `:' to `.' as module separator for output.
compiler/mercury_to_mercury.m:
compiler/prog_io_typeclass.m:
As above.
Fixed a bug where `.' was not being recognised as a module separator.
doc/reference_manual.texi:
Report the change.
library/term_io.m:
Ensure that infix `.' is written without surrounding spaces.

Test case added.

Make smart recompilation work where the module name doesn't
match the file name (e.g. in the compiler).
compiler/modules.m:
Where the module name doesn't match the file name
and there is a Mercury.modules file, pass the
module name to mmc, not the file name.
compiler/source_file_map.m:
Add a predicate `have_source_file_map' for use
by modules.m.
Don't put the Mercury.modules file in the Mercury
subdirectory. It's the user's responsibility to clean
it up, so it should be in the main directory.
compiler/mercury_compile.m:
Suggest creating the Mercury.modules file if passed
a file name which doesn't match the module name.
compiler/Mmakefile:
browser/Mmakefile:
Generate the Mercury.modules file.
tests/hard_coded/Mmakefile:
The Mercury.modules file is no longer generated in
the Mercury subdirectory.

compiler/source_file_map.m:
Fix a bug which caused the Mercury.modules file to be
re-read on each lookup of a source file name.
Estimated hours taken: 8
Branches: main
Allow arbitrary mappings from source file name to module name.
The mapping is created using the command `mmc -f *.m', which must
be run before `mmake depend'.
compiler/parse_tree.m:
compiler/source_file_map.m:
compiler/notes/compiler_design.html:
Add a new module to read, write and search the mapping.
compiler/modules.m:
Use the source file map when searching for source files.
Export `make_directory' for use by source_file_map.m.
Use the module name rather than the source file name to
generate the executable name. This matches the documentation
in the User's Guide, and it's needed to make the tests work.
compiler/prog_io.m:
Separate out the code to read the first item in a module to
find the module name into a new predicate, `find_module_name'.
compiler/handle_options.m:
Don't complain about the module name not matching the file
name when generating the Mercury.modules file -- the file
only needs to be generated when the module name doesn't
match the file name.
compiler/llds_out.m:
Remove a duplicate copy of `make_directory'.
compiler/options.m:
compiler/mercury_compile.m:
doc/user_guide.texi:
Add the `--generate-source-file-mapping' (-f) option
to generate the mapping.
NEWS:
Document the change.
tests/hard_coded/Mmakefile:
tests/hard_coded/source_file_map.m:
tests/hard_coded/mapped_module.exp:
Test case.
