We make it possible to deprecate tactics defined by `Ltac`, `Tactic
Notation` or ML.
For the first two variants, we anticipate the syntax of attributes:
`#[deprecated(since = "XX", note = "YY")]`
In ML, the syntax is:
```
let reflexivity_depr =
let open CWarnings in
{ since = "8.5"; note = "Use admit instead." }
TACTIC EXTEND reflexivity DEPRECATED reflexivity_depr
[ "reflexivity" ] -> [ Tactics.intros_reflexivity ]
END
```
A warning is shown at the point where the tactic is used (either
a direct call or when defining another tactic):
Tactic `foo` is deprecated since XX. YY
YY is typically meant to be "Use bar instead.".

Coqpp has nothing to do with `grammar`, we thus place it in its own
directory, which will prove convenient in more modular build systems.
Note that we add `coqpp` to the list of global includes, we could have
indeed added some extra rules, but IMHO not worth it as hopefully
proper containment will be soon checked by Dune.

There was a conflict in the name of an exported function. A good argument in
favour of PR #7898.

It was forcing the macro to generate code that was useless.

The parser is stupid and the syntax is almost the same as the previous one.
The only difference is that one needs to wrap OCaml code between { braces }
so that quoting works out of the box.
Files requiring such a syntax are handled specifically by the type system
and need to have a .mlg extension instead of a .ml4 one.
|
|
Today, TACTIC EXTEND generates ad-hoc ML code that registers the tactic
and its parsing rule. Instead, we make it generate a typed AST that is
passed to the parser and a generic tactic execution routine.
PMP has written a small parser that can generate the same typed ASTs
without relying on camlp5, which is overkill for such simple macros.

In current code, `Proofview.Goal.t` uses a phantom type to indicate
whether the goal was properly substituted wrt current `evar_map` or
not.
After the introduction of `EConstr`, this distinction should have
become unnecessary, thus we remove the phantom parameter from
`'a Proofview.Goal.t`. This may introduce some minor incompatibilities
at the typing level. Code-wise, things should remain the same.
We thus deprecate `assume`. In a next commit, we will remove
normalization as much as possible from the code.

It was left ignored after 8089dc960c9e8caf778907fd87be48d77b066433.

Together with #1122, this makes `VernacInstance` the only command in
the Coq codebase that cannot be statically determined to open a proof.
The reasoning for the commands moved to `VtSideff` is that
parser-altering commands should be always marked `VtNow`; the rest can
be usually marked as `VtLater`.
|
|
|
|
To that extent we introduce a new prototype vernacular extension macro
`VERNAC COMMAND FUNCTIONAL EXTEND` that will take a function with the
proper parameters and attributes.
This of course needs more refinement, in particular we should move
`vernac_command` to its own file and make `Vernacentries` consistent
wrt it.
|
|
This is a continuation on #6183 and another step towards a more
functional interpretation of commands.
In particular, this should allow us to remove the locality hack.
|
|
To this purpose we allow plugins to register functions that will
modify the state.
This is not used yet, but will be used soon when we remove the global
handling of the proof state.

In Tactic Notation and TACTIC EXTEND, when an argument not ending with
"_list_sep" was given with a separator, the separator was silently
ignored.
Now:
- we take it into account if it is a list (i.e. ending with "_list"), as if
"_list_sep" was given, since after all, the "_sep" is useless in the name.
- we fail if there is a separator but it is not a "_list" or "_list_sep".

Originally, it was not possible to define a new vernacular command
in the following way:
VERNAC COMMAND EXTEND Cmd6 CLASSIFIED AS QUERY
[ "SomeCmd" ] -> [ Feedback.msg_notice ?loc (Pp.str "some message") ]
END
because "loc : Loc.t" was not bound.
This commit fixes that, i.e. the location of the custom Vernacular command
(within *.v file) is made available as "loc" variable bound on the right side
of "->" .

It is empty and not used anymore.

This fixes bug 5650: evar (x : Prop) should not be slow.
|
|
This ensures that the API is self-contained and is, well, an API.
Before this patch, the contents of `API.mli` bore little relation with
what was used by the plugins [example: `Metasyntax` in tacentries.ml].
Many missing types had to be added.
A sanity check of the `API.mli` file can be done with:
`ocamlfind ocamlc -rectypes -package camlp5 -I lib API/API.mli`

Reminder of (some of) the reasons for removal:
- Despite the claim in sigma.mli, it does *not* prevent evar
leaks, something like:
fun env evd ->
let (evd',ev) = new_evar env evd in
(evd,ev)
will typecheck even with Sigma-like type annotations (with a proof of
reflexivity)
- The API stayed embryonic. Even typing functions were not ported to
Sigma.
- Some unsafe combinators (Unsafe.tclEVARS) were replaced with slightly
less unsafe ones (e.g. s_enter), but those ones were not marked unsafe
at all (despite still being so).
- There was no good story for higher order functions manipulating evar
maps. Without higher order, one can most of the time get away with
reusing the same name for the updated evar map.
- Most of the code doing complex things with evar maps was using unsafe
casts to sigma. This code should be fixed, but this is an orthogonal
issue.
Of course, this was showing a nice and elegant use of GADTs, but the
cost/benefit ratio in practice did not seem good.

As per https://github.com/coq/coq/pull/716#issuecomment-305140839
Partially using
```bash
git grep --name-only 'anomaly\s*\(~label:"[^"]*"\s*\)\?\(Pp.\)\?(\(\(Pp.\)\?str\)\?\s*".*[^\.!]")' | xargs sed s'/\(anomaly\s*\(~label:"[^"]*"\s*\)\?\(Pp.\)\?(\(\(Pp.\)\?str\)\?\s*".*\s*[^\.! ]\)\s*")/\1.")/g' -i
```
and
```bash
git grep --name-only ' !"' | xargs sed s'/ !"/!"/g' -i
```
The rest were manually edited by looking at the results of
```bash
git grep anomaly | grep '\.ml' | grep -v 'anomaly\s*\(~label:"[^"]*"\s*\)\?\(Pp\.\)\?(\(\(Pp.\)\?str\)\?\s*".*\(\.\|!\)")' | grep 'anomaly\($\|[^_]\)' | less
```

would write that code

`internal_ghost` was an artifact to ease porting of the ml4 rules. Now
that the location is optional we can finally get rid of it.
|
|
Now it is a private field, locations are optional.
|
|
It was failing after 1d0eb5d4d6fea.
|
|
We remove the camlp4 compatibility layer, and try to clean up
most structures. `parsing/compat` is gone.
We added some documentation to the lexer/parser interfaces that are
often obscured by module includes.
|
|
This adds at least support for camlp5 6.14 (in addition to 6.17).

The syntax is: TACTIC EXTEND foo AT LEVEL i
This commit makes it possible to define tacticals like the ssreflect
arrow without having to resort to GEXTEND statements and intepretation
hacks.
Note that it simply makes accessible through the ML interface what Tactic
Notation already supports:
Tactic Notation (at level 1) tactic1(t) "=>" ipats(l) := ...

Apparently, in camlp4 (unlike camlp5) :
- Something like "[ kwd = IDENT "foobar" -> .... kwd ... ]"
produces a kwd of type token instead of string (which sounds reasonable ?).
For now, I've replaced kwd by the explicit strings. Not so nice, but works
with both camlp4 and camlp5
- A quotation of the form "let obj = ... in bar; baz" is not
interpreted in the usual OCaml way, but rather as
"(let obj = ... in bar); baz".
Let's use instead "let obj = ... in let () = bar in baz", which works fine.
