| |/ |/| | | | | | | | | | | | | | | Morally, `library` should not depend on the vernacular definition. This will also create problems when trying to modularize the codebase due to the cycle [vernacs depend for example on constrexprs]. The fix is fortunately easy.

| | | | | | | | | | | | | | | | | | | | | | | | 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.
| | | * [econstr] Forbid calling `to_constr` in open terms.Gravatar Emilio Jesus Gallego Arias2018-03-31
| | |/ | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We forbid calling `EConstr.to_constr` on terms that are not evar-free, as to progress towards enforcing the invariant that `Constr.t` is evar-free. [c.f. #6308] Due to compatibility constraints we provide an optional parameter to `to_constr`, `abort` which can be used to overcome this restriction until we fix all parts of the code. Now, grepping for `~abort:false` should return the questionable parts of the system. Not a lot of places had to be fixed, some comments: - problems with the interface due to `Evd/Constr` [`Evd.define` being the prime example] do seem real! - inductives also look bad with regards to `Constr/EConstr`. - code in plugins needs work. A notable user of this "feature" is `Obligations/Program` that seem to like to generate kernel-level entries with free evars, then to scan them and workaround this problem by generating constants.

* [located] Push inner locations in `reference` to a CAst.t node.Gravatar Emilio Jesus Gallego Arias2018-03-09
| | | | | | | | | | | | | | The `reference` type contains some ad-hoc locations in its constructors, but there is no reason not to handle them with the standard attribute container provided by `CAst.t`. An orthogonal topic to this commit is whether the `reference` type should contain a location or not at all. It seems that many places would become a bit clearer by splitting `reference` into non-located `reference` and `lreference`, however some other places become messier so we maintain the current status-quo for now.

| | | | | | | | | | | 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.

This is confusingly different from the behaviour with [Type] and means cumulativity can only be used to lift between universes related by strict inequalities. (This isn't a kernel restriction so there might be some workaround to send the kernel the right constraints, but not in a nice way.) See modified test for more details of what is now possible. Technical notes: When universe constraints were inferred by comparing the shape of terms without reduction, cumulativity was not used and so too-strict equality constraints were generated. Then in order to use cumulativity we had to make this comparison fail to fall back to full conversion. When unifiying 2 instances of a cumulative inductive type, if there are any Irrelevant universes we try to unify them if they are flexible.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We limit fixpoints to Finite inductive types, so that BiFinite inductives (non-recursive records) are excluded from fixpoint construction. This is a regression in the sense that e.g. fixpoints on unit records were allowed before. Primitive records with eta-conversion are included in the BiFinite types.

| | | | * [toplevel] Respect COQ_COLORS environment variableGravatar Thomas Hebb2018-03-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since 3fc02bb2034a ("[pp] Move terminal-specific tagging to the toplevel."), the COQ_COLORS environment variable has been ignored, since init_terminal_output unconditionally called init_tag_map with the default colors, overwriting any custom colors that had been previously set. Fix this by creating a separate function, default_styles, to set the default colors. Also, remove the clear_styles function, as it was only called in one place and did nothing (since tag_map is empty to begin with).

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.

The changes here need careful review as the tradeoffs are subtle and still a lot of clean up remains to be done in `vernac/*`. We have opted for penalize [minimally] the few users coming from true `Constr`-land, but I am sure we can tweak code in a much better way. In particular, it is not clear if internalization should take an `evar_map` even in the cases where it is not triggered, see the changes under `plugins` for a good example. Also, the new return type of `Pretyping.understand` should undergo careful review. We don't touch `Impargs` as it is not clear how to proceed, however, the current type of `compute_implicits_gen` looks very suspicious as it is called often with free evars. Some TODOs are: - impargs was calling whd_all, the Econstr equivalent can be either + Reductionops.whd_all [which does refolding and no sharing] + Reductionops.clos_whd_flags with all as a flag.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This intermediate representation serves two purposes: 1- It is a preliminary step for primitive machine integers, as iterators will be compiled to Clambda. 2- It makes the VM compilation passes closer to the ones of native_compute. Once we unifiy the representation of values, we should be able to factorize the lambda-code generation between the two compilers, as well as the reification code. This code was written by Benjamin Grégoire and myself.
