We now accept the following code: Definition E := 0. Module E. End E.
Techically, we simply allow the same label to occur at most twice in
a structure_body, which is a (label * structure_field_body) list).
These two label occurences should not be at the same level of fields
(e.g. a SFBmodule and a SFBmind are ok, but not two SFBmodule's or
a SFBmodule and a SFBmodtype). Gain : a minimal amount of code change.
Drawback : no more simple List.assoc or equivalent should be performed
on a structure_body ...

Util only depends on Ocaml stdlib and Utf8 tables.
Generic pretty printing and loc functions are in Pp.
Generic errors are in Errors.
+ Training white-spaces, useless open, prlist copies random erasure.
Too many "open Errors" on the contrary.

I thought this situation wasn't possible, hence the Option.get.
But it's apparently legal to use Declare Module anywhere, even
outside a Module Type. No idea on how to handle that at extraction
for the moment, hence a proper "unsupported" error message.

In signatures, opaque terms are always seen as parameters.
In implementations, a flag Set/Unset Extraction AccessOpaque
allows to customize things:
- Set : opacity is ignored (this is the old behavior)
- Unset : opaque terms are extracted as axioms (default now)
Some warnings are anyway emitted when extraction encounters
informative opaque terms.

The recent experiment with -dont-load-proofs in the stdlib showed that
this options isn't fully safe: some axioms were generated (Include ?
functor application ? This is still to be fully understood).
Instead, I've implemented an idea of Yann: only load opaque proofs when
we need them. This is almost as fast as -dont-load-proofs (on the stdlib,
we're now 15% faster than before instead of 20% faster with -dont-load-proofs),
but fully compatible with Coq standard behavior.
Technically, the const_body field of Declarations.constant_body now regroup
const_body + const_opaque + const_inline in a ternary type. It is now either:
- Undef : an axiom or parameter, with an inline info
- Def : a transparent definition, with a constr_substituted
- OpaqueDef : an opaque definition, with a lazy constr_substitued
Accessing the lazy constr of an OpaqueDef might trigger the read on disk of
the final section of a .vo, where opaque proofs are located.
Some functions (body_of_constant, is_opaque, constant_has_body) emulate
the behavior of the old fields. The rest of Coq (including the checker)
has been adapted accordingly, either via direct access to the new const_body
or via these new functions. Many places look nicer now (ok, subjective notion).
There are now three options: -lazy-load-proofs (default), -force-load-proofs
(earlier semantics), -dont-load-proofs. Note that -outputstate now implies
-force-load-proofs (otherwise the marshaling fails on some delayed lazy).
On the way, I fixed what looked like a bug : a module type
(T with Definition x := c) was accepted even when x in T was opaque.
I also tried to clarify Subtyping.check_constant.

This is a mix of "Recursive Extraction" and "Extraction Library":
- like "Extraction Library", the extracted code is splitted in
separated files, one per coq source file.
- unlike "Extraction Library", but similarly to "Recursive Extraction",
not everything gets extracted, but only dependencies of some
initially-given elements
We prepare for a more clever dependency selection inside sub-modules.
For the moment all needed sub-modules are still fully extracted (other we
would need to fix signatures accordingly).

For Haskell, we still try to provide readable indentation,
but we now avoid relying on this indentation for correctness.
Instead, we use layout-independant syntax with { } when
necessary (after "case of" and "let"). It is much safer this
way, even if the syntax gets a bit more cumbersome.
For people allergic to {;}, they can most of the time do a
tr -d "{;}" without changing the meaning of the program.
Be careful nonetheless: since "case of" is now delimited,
some parenthesis that used to be mandatory are now removed.
Note also that the initial "module ... where" is still without
{ }: even when Format goes crazy it doesn't tamper with column 0.
Other modifications:
- Using "Set Printing Width" now affects uniformly the extraction
pretty-printers. You can set a greater value than the default 78
before extracting a program that you know to be "really deep".
- In ocaml (and also a bit in Haskell), we now try to avoid abusing
of 2-char-right-indentation. For instance | is now aligned with
the "m" of match. This way, max_indent will be reached less frequently.
- As soon as a pretty-print box contains an explicit newline,
we set its virtual size to a big number, in order to prevent this
box to be part of some horizontal arrangement.

As said in CHANGES:
<<
The inlining done during application of functors can now be controlled
more precisely. In addition to the "!F G" syntax preventing any inlining,
we can now use a priority level to select parameters to inline :
"<30>F G" means "only inline in F the parameters whose levels are <= 30".
The level of a parameter can be fixed by "Parameter Inline(30) foo".
When levels aren't given, the default value is 100. One can also use
the flag "Set Inline Level ..." to set a level.
>>
Nota : the syntax "Parameter Inline(30) foo" is equivalent to
"Set Inline Level 30. Parameter Inline foo.",
and "Include <30>F G" is equivalent to "Set Inline Level 30. Include F G."
For instance, in ZBinary, eq is @Logic.eq and should rather be inlined,
while in BigZ, eq is (fun x y => [x]=[y]) and should rather not be inlined.
We could achieve this behavior by setting a level such as 30 to the
parameter eq, and then tweaking the current level when applying functors.
This idea of levels might be too restrictive, we'll see, but at least
the implementation of this change was quite simple. There might be
situation where parameters cannot be linearly ordered according to their
"inlinablility". For these cases, we would need to mention names to inline
or not at a functor application, and this is a bit more tricky
(and might be a pain to use if there are many names).
No documentation for the moment, since this feature is experimental
and might still evolve.

Cf. coqdev for the details of the bug report.
- Protect some Hashtbl.find and other risky functions in order to avoid
as much as possible to end with an irritating Anomaly : Not_found.
- Re-enable in pp_ocaml_extern the case of a module-file used as
a module (e.g. module A' := A for A.v) when doing modular extraction.
- Rework the code that decides to "open" or not modules initially:
opening A when A contains a submodule B hides the file B even when
B isn't opened itself, we avoid that now.
- Fix some tables (sets or maps) used by extraction for which it is
critical to consider constants/inductives/global_reference _not_
modulo the equivalence of Elie, but rather via Pervasives.compare.
Still to do : avoid appearance of '_a in extracted code.

Extraction under modules is highly experimental, and just work a bit.
Don't expect too much of it. With this commit, I simply avoid a few
"assert false" to occur when we are under modules. But things are
still quite wrong, for instance with:
Definition foo.
Module M.
Definition bar := foo.
Recursive Extraction bar.
Extraction of bar is ok, but foo isn't displayed, since extraction
can't get it: Lib.contents_after doesn't mention it, it is probably
in some frozen summary.

And similarly for Haskell: we do not force capitalized/uncapitalized
filenames anymore, but we rather follow the name of the .v file (with
new extensions of course). Ok, this is an incompatible change, but
it is really convenient, some people where actually already doing
some hacks to have this behavior (cf. Compcert).

We use the mod_type_alg and typ_expr_alg field when they aren't
empty. As a consequences, many signatures are now simple
abbreviations, or "with" constructions, leading to .mli that are
_way_ shorter this way. Various fixups concerning the "with
Definition" syntax. In extract_seb_spec, we propagate both the alg
and non-alg versions of the structure, for handlying nicely the
"with" situation, and expanding situations not possible in ocaml.

- Add module parameters in the structure of visible_layer,
in order for module params to be part of name clash detection,
avoiding this way a source of potentially wrong code.
- In case of clash, module params are alpha-renamed to something
unique (Foo__XXX where XXX is the number contained in the mbid).
This solves some situations that were unsupported by extraction.
for instance the "Module F (X:T). Module X:=X. ... End F."
- We now check in Coq identifiers the presence of the
extraction-reserved string __. If it is found, we issue a warning
(which might become an error someday).

- For Haskell, modules abbreviations and applied functors are expanded.
The only remaining sitation that isn't supported is extracting functors
and applying them after extraction.
- Add a module extraction for Scheme with the same capabilities as for
Haskell (with no Extraction Library, though).
- Nicer extracted module types (use of the mb.mod_type_alg if present)

- Many of them were broken, some of them after Pierre B's rework
of mli for ocamldoc, but not only (many bad annotation, many files
with no svn property about Id, etc)
- Useless for those of us that work with git-svn (and a fortiori
in a forthcoming git-only setting)
- Even in svn, they seem to be of little interest

1- Management of the name-space in a modular development / sharing of non-logical objects.
2- Performance of atomic module operations (adding a module to the environment, subtyping ...).
1-
There are 3 module constructions which derive equalities on fields from a module to another:
Let P be a module path and foo a field of P
Module M := P.
Module M.
Include P.
...
End M.
Declare Module K : S with Module M := P.
In this 3 cases we don't want to be bothered by the duplication of names.
Of course, M.foo delta reduce to P.foo but many non-logical features of coq
do not work modulo conversion (they use eq_constr or constr_pat object).
To engender a transparent name-space (ie using P.foo or M.foo is the same thing)
we quotient the name-space by the equivalence relation on names induced by the
3 constructions above.
To implement this, the types constant and mutual_inductive are now couples of
kernel_names. The first projection correspond to the name used by the user and the second
projection to the canonical name, for example the internal name of M.foo is
(M.foo,P.foo).
So:
*************************************************************************************
* Use the eq_(con,mind,constructor,gr,egr...) function and not = on names values *
*************************************************************************************
Map and Set indexed on names are ordered on user name for the kernel side
and on canonical name outside. Thus we have sharing of notation, hints... for free
(also for a posteriori declaration of them, ex: a notation on M.foo will be
avaible on P.foo). If you want to use this, use the appropriate compare function
defined in name.ml or libnames.ml.
2-
No more time explosion (i hoppe) when using modules i have re-implemented atomic
module operations so that they are all linear in the size of the module. We also
have no more unique identifier (internal module names) for modules, it is now based
on a section_path like mechanism => we have less substitutions to perform at require,
module closing and subtyping but we pre-compute more information hence if we instanciate
several functors then we have bigger vo.
Last thing, the checker will not work well on vo(s) that contains one of the 3 constructions
above, i will work on it soon...

(uniformisation of function names, classification). One of the most
visible change is the renaming of section_path into full_path (the
use of name section was obsolete due to the module system, but I
don't know if the new name is the best chosen one - especially it
remains some "sp" here and there).
- Simplification of the interface of classify_object (first argument dropped).
- Simplification of the code for vernac keyword "End".
- Other small cleaning or dead code removal.
