We also get rid of ploc.ml, now useless, relying a priori on more
robust code in lStream.ml for location reporting (see
e.g. parse_parsable in grammar.ml).
|
|
This will ensure that we don't introduce problems as it has happened
in the past.
While we are at it, we fix one easy case of non-tail call.

We place creation and saving of interactive proofs in the same module;
this will allow to make `proof_entry` private, improving invariants
and control over clients, and to reduce the API [for example next
commit will move abstract declaration into this module, removing the
exported ad-hoc `build_constant_by_tactic`]
Next step will be to unify all the common code in the interactive /
non-interactive case; but we need to tweak the handling of obligations
first.

Latest refactorings allow us to make the signature Coq parser a
standard `Grammar.S` one; the only bit needed is to provide the extra
capabilities to the `Lexer` signature w.r.t. to comments state.
The handling of Lexer state is still a bit ad-hoc, in particular it is
global whereas it should be fully attached to the parsable. This may
work ok in batch mode but the current behavior may be buggy in the
interactive context.
This PR doesn't solve that but it is a step towards a more functional
solution.

There is not need to re-export Gramlib's API in a non-structured way
anymore. We thus expose the core Gramlib interface to users and remove
redundant functions.
A question about whether to move more parts of the API to `Gramlib` is
still open, as well as on naming.

Add headers to a few files which were missing them.

We make the primitives for backtrace-enriched exceptions canonical in
the `Exninfo` module, deprecating all other aliases.
At some point dependencies between `CErrors` and `Exninfo` were a bit
complex, after recent clean-ups the roles seem much clearer so we can
have a single place for `iraise` and `capture`.
|
|
As suggested by Pierre-Marie Pédrot, this is a more conservative
version of #8771 .
In this commit, we replace Coq's custom backtrace type with OCaml
`Printexc.raw_backtrace`; this seems to already give some improvements
in terms of backtraces [see below] and removes quite a bit of code.
Main difference in terms of API is that backtraces become now
first-class in `Exninfo`, and we seek to consolidate thus the
exception-related APIs in that module.
We also fix a bug in `vernac.ml` where the backtrace captured was the
one of `edit_at`.
Closes #6446

We place control attributes on their own, datatype, similarly to
regular attributes.
This is a step towards fixing #10452 , as we can now decouple control
attributes from the vernac AST itself, allowing to pass them
independently.
|
|
As reported by Karl Palmskog, some lists of arguments were supposed to
appear in reverse order whereas others do appear in the natural order
they are declared.
Given that in some cases, such as require, order is quite important,
we make the parsing return lists in the right order so clients don't
have to care about doing `List.rev`.

This has been a mess for quite a while, we try to improve it.

We alert users that `Vernacstate.Proof_global` is a Coq internal
module and should not be used to workaround lack of state threading.
|
|
In this way one can also set the current offsets in a file,
useful if you are parsing a Coq fragment within a file instead
of a full file starting from the first line.

Before #9263 this type was returned by the STM's `parse_sentence`, but
the type was lost on the generalization to entries.

DAG nodes hold now a system state and a parsing state.
The latter is always passed to the parser.
This paves the way to decoupling the effect of commands on the parsing
state and the system state, and hence never force to interpret, say,
Notation.
Handling proof modes is now done explicitly in the STM, not by interpreting
VernacStartLemma.
Similarly Notation execution could be split in two phases in order to obtain a
parsing state without fully executing it (that requires executing all
commands before it).

We deprecate the corresponding functions in Pcoq.Gram. The motivation is
that the Gram module is used as an argument to Camlp5 functors, so that
it is not stable by extension. Enforcing that its type is literally the
one Camlp5 expects ensures robustness to extension statically.
Some really internal functions have been bluntly removed. It is unlikely
that they are used by external plugins.
|
|
This is a first step towards moving REPL-specific commands out of the
core layers. In particular, we remove `Quit` and `Drop` from the core
vernacular to specific toplevel-level parsing rules.
|
|
We continue with the work of #402 and #6745 and update most of the
remaining parts of the AST:
- module declarations
- intro patterns
- top-level sentences
Now, parsed documents should be full annotated by `CAst` nodes.

Instead of using a command-analysis heuristic, coqtop will now print
goals if the goal has changed. We use a fast goal comparison
heuristic, but a more refined strategy would be possible.
This brings some [IMHO very welcome] change to PG and `-emacs`, which
will now disable the printing of goals. Now, instead of playing with
`Set/Unset Silent` and a bunch of other hacks, PG can issue a `Show`
command whenever it wishes to redisplay the goals.
This change will break PG, so we need to carefully coordinate this PR
with PG upstream (see ProofGeneral/PG#212).
Some interesting further things to do:
- Detect changes in nested proofs.
- Uncouple the silent flag from "print goals".

We first load the file, then we print it as a post-processing
step. This is both more flexible and clearer.
We also refactor the comments handling to minimize the logic that is
living in the Lexer. Indeed, the main API is now living in the
printer, and complex interactions with the state are not possible
anymore, including the removal of messing with low-level summary and
state setting!
|

Parsing in `VernacLoad` was broken for a while, but the situation has
improved by miscellaneous refactoring.
However, we still cannot support `Load` properly when proofs are
crossing file boundaries. So in this patch we do two things:
- We check for supported scenarios [no proofs open at `Load` entry/exit]
- Remove the hack in `toplevel` so the behavior of `Load` is
consistent between `coqide`/`coqc`.
We close #5053 as its main bug was fixed by the main toplevel
refactoring and the remaining cases are documented now.

We follow the suggestions in #402 and turn uses of `Loc.located` in
`vernac` into `CAst.t`. The impact should be low as this change mostly
affects top-level vernaculars.
With this change, we are even closer to automatically map a text
document to its AST in a programmatic way.
|
|
We organize the toplevel execution as a record and pass it
around. This will be used by future PRs as to for example decouple
goal printing from the classifier.
|

One less global flag.
|
|
Virtually all classifications of vernacular commands (the STM
classifier, "filtered commands", "navigation commands", etc.) were
broken in presence of control vernaculars like Time, Timeout, Fail.
Funny examples of bugs include Time Abort All in coqtop or Time Set Ltac
Debug in CoqIDE.
This change introduces a type separation between vernacular controls and
vernacular commands, together with an "under_control" combinator.
|
|
We'd like to handle proofs functionally we thus recommend not to use
printing functions without an explicit context.
We also adapt most of the code, making more explicit where the
printing environment is coming from.
An open task is to refactor some code so we gradually make the
`Pfedit.get_current_context ()` disappear.
|
|
We interpret meta-commands directly, instead of going by an
intermediate "classifier step".
The code could still use some further refactoring, in particular, the
`part_of_script` bit is a bit strange likely coming from some special
treatment of `VtMeta` in the `query` call, and should go away.
|

We move delicate library/module instillation code to the STM so the
API guarantees that the first state snapshot is correct. That was not
the case in the past, which meant that the STM cache was unsound in
batch mode, however we never used its contents due to not backtracking
to the first state.
This provides quite an improvement in the API, however more work is
needed until the codepath is fully polished.
This is a critical step towards handling the STM functionally.
|
|
We make the Stm API functional over an opaque `doc` type. This allows
to have a much better picture of what the toplevel is doing; now
almost all users of STM private data are marked by typing.
For now only, the API is functional; a PR switching the internals
should come soon thou; however we must first fix some initialization
bugs.
Due to some users, we modify `feedback` internally to include a
"document id" field; we don't expose this change in the IDE protocol
yet.

We move toplevel/STM flags from `Flags` to their proper components;
this ensures that low-level code doesn't depend on them, which was
incorrect and source of many problems wrt the interfaces.
Lower-level components should not be aware whether they are running in
batch or interactive mode, but instead provide a functional interface.
In particular:
== Added flags ==
- `Safe_typing.allow_delayed_constants`
Allow delayed constants in the kernel.
- `Flags.record_aux_file`
Output `Proof using` information from the kernel.
- `System.trust_file_cache`
Assume that the file system won't change during our run.
== Deleted flags ==
- `Flags.compilation_mode`
- `Flags.batch_mode`
Additionally, we modify the STM entry point and `coqtop` to account
for the needed state. Note that testing may be necessary and the
number of combinations possible exceeds what the test-suite / regular
use does.
The next step is to fix the initialization problems [c.f. Bugzilla],
which will require a larger rework of the STM interface.

Undo & friends is very expensive in batch mode as backtracking state
is not kept and thus should be recomputed.
We thus warn the user.

An incoming commit is removing some toplevel-specific global flags in
favor of local toplevel state; this commit flags `Flags` use so it
becomes clearer in the code whether we are relying on some "global"
settable status in code.
A good candidate for further cleanup is the pattern:
`Flags.if_verbose Feedback.msg_info`

This is a second try at removing the hooks for the legacy xml export
system which can't currently be tested.
It is also not included in the API, so it should either be included in
it or this PR be applied.
