`CoqProject_file` uses the feedback system, however this is not very
convenient in some scenarios such as `coqdep` that has to be run very
early in the build process [and thus in "boot" mode].
We thus make the warning function a paramater.
Should fix #8913.

Fix #8989.
This adds an option -topfile taking a path so that inferring the right
dirpath is done by the toplevel after processing -Q/-R instead of the
client having to do it.

Fix incorrect change to raw diffs in shorten_diff_span

This is to ensure that the corresponding question boxes remains in
front of the main window, consistently with the fact that they are
blocking actions on the main window.
|
|
The "parent" option allows to attach the box to the parent box. This
ensures that the dialog box, which blocks action on the main window,
does not get hidden by the main window.
Idem for the message_box.
|
|
We do it by passing the name of the main window in the "parent"
option. Formerly, the window could be hidden but nevertheless blocking
any action on the main window. With the change, it can be moved
aside, but never hidden by the main window.
Tested on MacOS X.

This was obsolete since new completion in 945d7db9 (then a07359f6).
|
|
First, they already work by default. Second, by rebinding them, they
cannot be used any longer in the completion menu, which is a bit
annoying.
|
|
We should install the files in `share/coqide` instead of the current
`coq` location; but we defer this change until we are more advanced in
the make-phase out.
Fixes: #8953

This is a bit more portable.

gtk_scrolled_window_add_with_viewport)

When opening the query pane, do not try to focus on a query tab that no
longer exists.

Gtk complains that we are not using gtk_scrolled_window_add_with_viewport,
so let us do.

- `CString.strip -> String.trim`
- `CString.split -> String.split_on_char`
As noted by @ppedrot there are some small differences on semantics:
> OCaml's `trim` also takes line feeds (LF) into account. Similarly,
> OCaml's `split` never returns an empty list whereas Coq's `split`
> does on the empty string.

Lintian found some spelling errors in the Debian packaging for coq. Fix
them most places they appear in the current source. (Don't change
documentation anchor names, as that would invalidate external
deeplinks.)
This also fixes a bug in coqdoc: prior to this commit, coqdoc would
highlight `instanciate` but not `instantiate`.

Even if `fake_ide` was under tools, it depended on libraries from
`ide`. Thus, we move `fake_ide` to `ide`, and make it "private" to the
test-suite [this means `test-suite` depends on the `ide` folder then].
In the Dune side, we reorganize libraries so `fake_ide` doesn't depend
on GTK anymore, this allows to run the test-suite when GTK is not
available.
In order to achieve this, we had to split the `coqide` package in a
server and client version.

After some discussion upstream, I think that for the current a
multi-package setup in a single repository this setup saves a bit
work.
The most problematic bit is the `-rectypes` flag; its status is not
saved per-library so we must either duplicate the flags in the coqide
scope (scope == dune-project file), or unify its scope with Coq. We do
this last option as this seems like the easiest thing for now.
Changes:
- Move coqide.opam file to the root, use a single scope/`dune-project` file.
- Remove `dune-workspace`, this should be owned by the developer / user.
|
|
The Dune `release` profile is used by OPAM so that should cover the
testing.
We also update the dependencies:
- camlp5: 7.01 had some bugs regarding grammar; we could use 7.02,
however this version it is not in OPAM. So I guess that leaves us
with 7.03 again.
- lablgtk < 2.18.5 does not support OCaml >= 4.05.0.

These are unused and not likely to come back.

As noted by @anton-trunov, this is more useful for development and
debug.

proof states. That's not always correct. This change will a) show diffs
for all displayed goals and b) correctly match goals between the old and
new proof states.
For example, "split." will show diffs for both resulting goals.
"all: swap 1 2" will show the same diffs as for the old proof state, though
in a different position in the output.
Please see comments before Proof_diffs.make_goal_map_i and Proof_diffs.match_goals
for a description of how goals are matched between old and new proofs.

"Print Options"

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.

3) Generate a warning message if the user enters a "Set Diffs xx" command.
4) Tweak display names for diffs in View menu.

For some reason the code was just doing random stuff that did not make
sense.

Proof General requires minor changes to make the diffs visible, but this code
shouldn't break the existing version of PG.
Diffs are computed for the hypotheses and conclusion of the first goal between
the old and new proofs. Strings are split into tokens using the Coq lexer,
then the list of tokens are diffed using the Myers algorithm. A fixup routine
(Pp_diff.shorten_diff_span) shortens the span of the diff result in some cases.
Diffs can be enabled with the Coq commmand "Set Diffs on|off|removed." or
"-diffs on|off|removed" on the OS command line. The "on" option shows only the
new item with added text, while "removed" shows each modified item twice--once
with the old value showing removed text and once with the new value showing
added text.
The highlights use 4 tags to specify the color and underline/strikeout.
These are "diffs.added", "diffs.removed", "diffs.added.bg" and "diffs.removed.bg".
The first two are for added or removed text; the last two are for
unmodified parts of a modified item.
Diffs that span multiple strings in the Pp are tagged with "start.diff.*" and
"end.diff.*", but only on the first and last strings of the span.

Fixes #8067. This is becoming the default in many developments, so it
makes sense to require it too, both for Coq and for Plugins.

For now we only copy the templates, but we could do more fancy stuff.
This helps to be compatible with build systems that take care of these
files automatically, see:
