2019-01-24[STM] explicit handling of parsing statesEnrico Tassi
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).

2018-12-14[proof] Rework proof interface.Emilio Jesus Gallego Arias
- deprecate the old 5-tuple accessor in favor of a view record, - move `name` and `kind` proof data from `Proof_global` to `Proof`, this will prove useful in subsequent functionalizations of the interface, in particular this is what abstract, which lives in the monads, needs in order no to access global state. - Note that `Proof.t` and `Proof_global.t` are redundant anyways.

2018-11-09[topfmt] Add phase attribute for toplevel printing.Emilio Jesus Gallego Arias
This is localized version of #8833, but instead of adding a phase attribute which, as pointed by @gares has some problematic semantics, we add a local one to the toplevel functions. This moves the imperative part of the API to a better-delimited scope and allows to progress with the separation of the interactive and compilation API. Note that still quite a few issues do remain in the "Feedback" path, for example, idetop and other feedback clients cannot get a hold of the feedback early enough as to direct init messages to the IDE part. This is for example a serious issue of the API that shall be treated separately.

2018-07-31Code to handle "Back" command for diffs.Jim Fehrle
2018-07-23Displays the differences between successive proof steps in coqtop and CoqIDE.Jim Fehrle
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.
2018-07-07Introduce a Pcoq.Entry module for functions that ought to be exported.Pierre-Marie Pédrot
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.
2018-05-21[stm] Make toplevels standalone executables.Emilio Jesus Gallego Arias
We turn coqtop "plugins" into standalone executables, which will be installed in `COQBIN` and located using the standard `PATH` mechanism. Using dynamic linking for `coqtop` customization didn't make a lot of sense, given that only one of such "plugins" could be loaded at a time. This cleans up some code and solves two problems: - `coqtop` needing to locate plugins, - dependency issues as plugins in `stm` depended on files in `toplevel`. In order to implement this, we do some minor cleanup of the toplevel API, making it functional, and implement uniform build rules. In particular: - `stm` and `toplevel` have become library-only directories, - a new directory, `topbin`, contains the new executables, - 4 new binaries have been introduced, for coqide and the stm. - we provide a common and cleaned up way to locate toplevels.
2018-05-02Making explicit that errors happen in one of five executation phases.Hugo Herbelin
The five phases are command line interpretation, initialization, prelude loading, rcfile loading, and sentence interpretation (only the two latters are located). We then parameterize the feedback handler with the given execution phase, so as to possibly annotate the message with information pertaining to the phase.
2018-04-11[warnings] Remove `set_current_loc` hack.Emilio Jesus Gallego Arias
Instead of the current hack that won't work as soon as we check some part of the document asynchronously, we make the warning processor recover a proper location if the warning doesn't have one attached. This is what CoqIDE does [but it queries it's own document model]. Fixes: #6172

2018-04-01[stm] Move VernacBacktrack to the toplevel.Emilio Jesus Gallego Arias
This command is legacy, equivalent to `EditAt` and only used by Emacs. We move it to the toplevel so we can kill some legacy code and in particular the `part_of_script` hack.
2018-03-11[vernac] Move `Quit` and `Drop` to the toplevel layer.Emilio Jesus Gallego Arias
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.
2018-03-05[toplevel] Modify printing goal strategy.Emilio Jesus Gallego Arias
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".

2018-02-28[toplevel] Update state when `Drop` exception is thrown [#6872]Emilio Jesus Gallego Arias
`Drop` is implemented using exceptions-as-control flow, so the toplevel state gets corrupted as `do_vernac` will never return when `Drop` occurs in the input. The right fix would be to remove `Drop` from the vernacular and make it a toplevel-only command, but meanwhile we can just patch the state in the exception handler. We also need to keep the global state in `Coqloop` as the main `coqtop` entry point won't be called by `go ()`. Fixes #6872.

2018-02-09[error] Replace msg_error by a proper exception.Emilio Jesus Gallego Arias
The current error mechanism in the core part of Coq is 100% exception based; there was some confusion in the past as to whether raising and exception could be replace with `Feedback.msg_error`. As of today, this is not the case [due to some issues in the layer that generates error feedbacks in the STM] so all cases of `msg_error` must raise an exception of print at a different level [for now].

2017-10-06[stm] Switch to a functional APIEmilio Jesus Gallego Arias
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.

2017-05-05[toplevel] Fix a couple of logical errors in error printing.Emilio Jesus Gallego Arias
In 4abb41d008fc754f21916dcac9cce49f2d04dd6d we switched back to use exceptions for error printing. However a couple of mistakes were present in that commit: - We wrongly absorbed the exception on `Vernac.compile`. However, it should be propagated as the caller will correctly print the error now. This introduced a critical bug as now `coqc` return the wrong exit status on error, breaking all sort of things. - We printed parsing exceptions twice; now it is not necessary to print the exception in the parsing handler as it will be propagated. I've checked this commit versus all previously reported bugs and it seems to work; we should definitively add a test-suite case to check that the exit code of `coqc` is correct, plus several other cases such as bugs https://coq.inria.fr/bugs/show_bug.cgi?id=5467 https://coq.inria.fr/bugs/show_bug.cgi?id=5485 https://coq.inria.fr/bugs/show_bug.cgi?id=5484 etc...

2017-04-25[toplevel] Use exception information for error printing.Emilio Jesus Gallego Arias
This is a partial backtrack on 63cfc77ddf3586262d905dc351b58669d185a55e. In that commit, we disregarded exception and tried to print error messages just by listening to feedback. However, feedback error messages are not always emitted due to https://coq.inria.fr/bugs/show_bug.cgi?id=5479 Thus meanwhile it is safer to go back to printing the information present in exceptions until we tweak the STM. This fixes https://coq.inria.fr/bugs/show_bug.cgi?id=5467 and many other glitches not reported, such errors in nested proofs.
2017-04-25[location] Make location optional in Loc.locatedEmilio Jesus Gallego Arias
This completes the Loc.ghost removal, the idea is to gear the API towards optional, but uniform, location handling. We don't print <unknown> anymore in the case there is no location. This is what the test suite expects. The old printing logic for located items was a bit inconsistent as it sometimes printed <unknown> and other times it printed nothing as the caller checked for `is_ghost` upstream.

2017-04-05[toplevel] Remove exception error printer in favor of feedback printer.Emilio Jesus Gallego Arias
We solve https://coq.inria.fr/bugs/show_bug.cgi?id=4789 by printing all the errors from the feedback handler, even in the case of coqtop. All error display is handled by a single, uniform path. There may be some minor discrepancies with 8.6 as we are uniform now whereas 8.6 tended to print errors in several ways, but our behavior is a subset of the 8.6 behavior. We had to make a choice for `-emacs` error output, which used to vary too. We have chosen to display error messages as: ``` (location info) option \n (program caret) option \n MARKER[254]Error: msgMARKER[255] ``` This commit also fixes: - https://coq.inria.fr/bugs/show_bug.cgi?id=5418 - https://coq.inria.fr/bugs/show_bug.cgi?id=5429
