In #7860 `Sys.executable_name` was introduced to locate coq private
binaries; however, this breaks use cases with symlinks, such as Dune.
In order to fix this, we adopt a simpler strategy; we will always
adapt the name originally provided by the user, and only add a
directory if it was originally present.
This should work (hopefully) in all cases.
This fixes `coqide` not working on Dune builds.

[Dune](https://github.com/ocaml/dune) is a compositional declarative
build system for OCaml. It provides automatic generation of
`version.ml`, `.merlin`, `META`, `opam`, API documentation; install
management; easy integration with external libraries, test runners,
and modular builds.
In particular, Dune uniformly handles components regardless whether
they live in, or out-of-tree. This greatly simplifies cases where a
plugin [or CoqIde] is checked out in the current working copy but then
distributed separately [and vice-versa]. Dune can thus be used as a
more flexible `coq_makefile` replacement.
For now we provide experimental support for a Dune build. In order to
build Coq + the standard library with Dune type:
```
$ make -f Makefile.dune world
```
This PR includes a preliminary, developer-only preview of Dune for
Coq. There is still ongoing work, see
https://github.com/coq/coq/issues/8052 for tracking status towards
full support.
## Technical description.
Dune works out of the box with Coq, once we have fixed some modularity
issues. The main remaining challenge was to support `.vo` files.
As Dune doesn't support custom build rules yet, to properly build
`.vo` files we provide a small helper script `tools/coq_dune.ml`. The
script will scan the Coq library directories and generate the
corresponding rules for `.v -> .vo` and `.ml4 -> .ml` builds. The
script uses `coqdep` as to correctly output the dependencies of
`.v` files. `coq_dune` is akin to `coq_makefile` and should be able to
be used to build Coq projects in the future.
Due to this pitfall, the build process has to proceed in three stages:
1) build `coqdep` and `coq_dune`; 2) generate `dune` files for
`theories` and `plugins`; 3) perform a regular build with all
targets are in scope.
## FAQ
### Why Dune?
Coq has a moderately complex build system and it is not a secret that
many developer-hours have been spent fighting with `make`.
In particular, the current `make`-based system does offer poor support
to verify that the current build rules and variables are coherent, and
requires significant manual, error-prone. Many variables must be
passed by hand, duplicated, etc... Additionally, our make system
offers poor integration with now standard OCaml ecosystem tools such
as `opam`, `ocamlfind` or `odoc`. Another critical point is build
compositionality. Coq is rich in 3rd party contributions, and a big
shortcoming of the current make system is that it cannot be used to
build these projects; requiring us to maintain a custom tool,
`coq_makefile`, with the corresponding cost.
In the past, there has been some efforts to migrate Coq to more
specialized build systems, however these stalled due to a variety of
reasons. Dune, is a declarative, OCaml-specific build tool that is on
the path to become the standard build system for the OCaml ecosystem.
Dune seems to be a good fit for Coq well: it is well-supported, fast,
compositional, and designed for large projects.
### Does Dune replace the make-based build system?
The current, make-based build system is unmodified by this PR and kept
as the default option. However, Dune has the potential
### Is this PR complete? What does it provide?
This PR is ready for developer preview and feedback. The build system
is functional, however, more work is necessary in order to make Dune
the default for Coq.
The main TODOs are tracked at https://github.com/coq/coq/issues/8052
This PR allows developers to use most of the features of Dune today:
- Modular organization of the codebase; each component is built only
against declared dependencies so components are checked for
containment more strictly.
- Hygienic builds; Dune places all artifacts under `_build`.
- Automatic generation of `.install` files, simplified OPAM workflow.
- `utop` support, `-opaque` in developer mode, etc...
- `ml4` files are handled using `coqp5`, a native-code customized
camlp5 executable which brings much faster `ml4 -> ml` processing.
### What dependencies does Dune require?
Dune doesn't depend on any 3rd party package other than the OCaml compiler.
### Some Benchs:

This is not optimal for we have to rebuild the `.cmi` as
`ocamldoc` cannot yet use the `_install_ci/` directory.
Overall the `mli` documentation is in a sorry state, however, I think
this is a first step in order to improve it.
Note that the `ml-doc` target seems broken in OCaml 4.07.0, needs
investigation.

Notations were not initially designed to support independent parsing
and printing rules. Some redesign of this part of the code shall be
necessary at some time.

The overlay for HoTT should be merged right after this PR.

Numeral Notations are not well-supported inside functors. We now give a
proper error message rather than an anomaly when this occurs.

Thanks to Emilio and Pierre-Marie Pédrot for pointers.

Because that's the sane thing to do.
This will inevitably cause issues for projects which do not `Import
Coq.Strings.Ascii` before trying to use ascii notations.
We also move the syntax plugin for `int31` notations from `Cyclic31` to
`Int31`, so that users (like CompCert) who merely `Require Import
Coq.Numbers.Cyclic.Int31.Int31` get the `int31` numeral syntax. Since
`Cyclic31` `Export`s `Int31`, this should not cause any additional
incompatibilities.
|
|
Aliases of global references can now be used in numeral notations
|
|
Now we support using inductive constructors and section-local variables
as numeral notation printing and parsing functions.
I'm not sure that I got the econstr conversion right.

I decided to make it a warning because it seems more flexible that way;
users to are flipping back and forth between option types and not option
types while designing won't have to update their `abstract after`
directives to do so, and users who don't want to allow this can make it an
actual error message.

Also make `Check S` no longer anomaly
Add a couple more test cases for numeral notations
Also add another possibly-confusing error message to the doc.

Some of this code is cargo-culted or kludged to work.
As I understand it, the situation is as follows:
There are two sorts of use-cases that need to be supported:
1. A plugin registers an OCaml function as a numeral interpreter. In
this case, the function registration must be synchronized with the
document state, but the functions should not be marshelled / stored
in the .vo.
2. A vernacular registers a Gallina function as a numeral interpreter.
In this case, the registration must be synchronized, and the function
should be marshelled / stored in the .vo.
In case (1), we can compare functions by pointer equality, and we should
be able to rely on globally unique keys, even across backtracking.
In case (2), we cannot compare functions by pointer equality (because
they must be regenerated on unmarshelling when `Require`ing a .vo file),
and we also cannot rely on any sort of unique key being both unique and
persistent across files.
The solution we use here is that we ask clients to provide "unique"
keys, and that clients tell us whether or not to overwrite existing
registered functions, i.e., to tell us whether or not we should expect
interpreter functions to be globally unique under pointer equality. For
plugins, a simple string suffices, as long as the string does not clash
between different plugins. In the case of vernacular-registered
functions, use marshell a description of all of the data used to
generate the function, and use that string as a unique key which is
expected to persist across files. Because we cannot rely on
function-pointer uniqueness here, we tell the
interpretation-registration to allow overwriting.
----
Some of this code is response to comments on the PR
----
Some code is to fix an issue that bignums revealed:
Both Int31 and bignums registered numeral notations in int31_scope. We
now prepend a globally unique identifier when registering numeral
notations from OCaml plugins. This is permissible because we don't
store the uid information for such notations in .vo files (assuming I'm
understanding the code correctly).
