2019-08-26Make kernel parametric on the lowest universe and fix #9294Matthieu Sozeau
This could be Prop (for compat with usual Coq), Set (for HoTT), or actually an arbitrary "i". Take lower bound of universes into account in pretyping/engine Reinstate proper elaboration of SProp <= l constraints: replacing is_small with equality with lbound is _not_ semantics preserving! lbound = Set Elaborate template polymorphic inductives with lower bound Prop This will make more constraints explicit Check univ constraints with Prop as lower bound for template inductives Restrict template polymorphic universes to those not bounded from below Fixes #9294 fix suggested by Matthieu Try second fix suggested by Matthieu Take care of modifying elaboration for record declarations as well. Rebase and export functions for debug Remove exported functions used while debugging Add a new typing flag "check_template" and option "-no-template-checl" This parameterizes the new criterion on template polymorphic inductives to allow bypassing it (necessary for backward compatibility). Update checker to the new typing flags structure Switch on the new template_check flag to allow old unsafe behavior in indTyping. This is the only change of code really impacting the kernel, together with the commit implementing unbounded from below and parameterization by the lower bound on universes. Add deprecated option `Unset Template Check` allowing to make proof scripts work with both 8.9 and 8.10 for a while Fix `Template Check` option name and test it Add `Unset Template Check` to Coq89.v Cooking of inductives and template-check tests Cleanup test-suite file for template check / universes(template) flags cookind tests Move test of `Unset Template Check` to the failure/ dir, but comment it for now Template test-suite test explanation Overlays for PR 9918 Overlay for paramcoq Add overlay for fiat_parsers (-no-template-check) Add overlay for fiat_crypto_legacy Update fiat-crypto legacy overlay Now it points at the version that I plan on merging; I am hoping that doing this will guard against mistakes by adding an extra check that the target tested by Coq's CI on this branch works with the change I made. Remove overlay that should no longer be necessary The setting in the compat file should handle it Remove now-merged fiat-crypto-legacy overlay Update `Print Assumptions` to reflect the typing flag for template checking Fix About and Print Assumptions for template poly, giving info on which variables are actually polymorphic Fix pretty printing to print global universe levels properly Fix printing of template polymorphic universes Fix pretty printing for template polymorphism on no universe Fix interaction of template check and universes(template) flag Fix indTyping to really check if there is any point in polymorphism: the conclusion sort should be parameterized over at least one local universe Indtyping fixes for template polymorphic Props Allow explicit template polymorphism again Adapt to new indTyping interface Handle the case of template-polymorphic on no universes correctly (morally Type0m univ represented as Prop). Fix check of meaningfullness of template polymorphism in the kernel. It is now done w.r.t the min_univ, the minimal universe inferred for the inductive/record type, independently of the user-written annotation which must only be larger than min_univ. This preserves compatibility with UniMath and template-polymorphism as it has been implemented up-to now. Comment on identity non-template-polymorphism Remove incorrect universes(template) attributes from ssr simpl_fun can be meaningfully template-poly, as well as pred_key (although the use is debatable: it could just as well be in Prop). Move `fun_of_simpl` coercion declaration out of section to respect uniform inheritance Remove incorrect uses of #[universes(template)] from the stdlib Extraction of micromega changes due to moving an ind decl out of a section Remove incorrect uses of #[universes(template)] from plugins Fix test-suite files, removing incorrect #[universes(template)] attributes Remove incorrect #[universes(template)] attributes in test-suite Fix test-suite Remove overlays as they have been merged upstream.

2019-05-23Fixing typos - Part 3JPR
2019-02-28Implement a method for manual declaration of implicits.Jasper Hugunin
This is intended to be separate from handling of implicit binders. The remaining uses of declare_manual_implicits satisfy a lot of assertions, giving the possibility of simplifying the interface in the future. Two disabled warnings are added for things that currently pass silently. Currently only Mtac passes non-maximal implicits to declare_manual_implicits with the force-usage flag set. When implicit arguments don't have to be named, should move Mtac over to set_implicits.
2019-01-23Pass some files to strict focusing mode.Gaëtan Gilbert
ie default goal selector ! How to do this: - change the default value of default goal selector in goal_select.ml - eval the emacs code in this commit message - compile Coq and in each erroring file repeatedly run [C-c f] (my/maybe-fix-buller-error) then [C-c C-b] (proof-process-buffer) until there are no errors (NB the first [C-c f] has no effect). You need to watch for 2 cases: - overly deep proofs where the bullets need to go beyond the list in my/bullet-stack (6 layers is enough the vast majority of the time though). The system will give you an error and you need to finish the lemma manually. - weird indentation when a bullet starts in the middle of a line and doesn't end in that line. Just reindent as you like then go to the next error and continue. ~~~emacs-lisp (defconst my/bullet-stack (list "-" "+" "*" "--" "++" "**") "Which bullets should be used, in order.") (defvar-local my/bullet-count nil "The value in the car indicates how many goals remain in the bullet at (length-1), and so on recursively. nil means we haven't started bulleting the current proof.") (defvar-local my/last-seen-qed nil) (defun my/get-maybe-bullet-error () "Extract the number of focused goals from the ! selector error message." (when-let* ((rbuf (get-buffer "*response*")) (str (with-current-buffer "*response*" (buffer-string))) (_ (string-match (rx "Error: Expected a single focused goal but " (group (+ digit))) str)) (ngoals (string-to-number (match-string 1 str)))) ngoals)) (defun my/bullet-fix-indent () "Auto indent until the next Qed/Defined, and update my/last-seen-qed." ;; (insert (format "(* %s -> %s *)\n" my/prev-count my/bullet-count)) (when-let ((qed (save-excursion (search-forward-regexp (rx (or "Defined." "Qed.")) nil t)))) (set-marker my/last-seen-qed qed) (indent-region (- (point) 1) qed))) (defun my/nth-bullet (n) "Get nth bullet, erroring if n >= length my/bullet-stack" (or (nth n my/bullet-stack) (error "Too many bullets."))) (defun my/maybe-fix-bullet-error (&optional arg) "Main function for porting a file to strict focusing. Repeatedly process your file in proof general until you get a focusing error, then run this function. Once there are no more errors you're done. Indentation commonly looks bad in the middle of fixing a proof, but will be fixed unless you start a bullet in the middle of a line and don't finish it in that line. ie in 'tac1. - tac2.\n tac3.' tac3 will get indented to align with tac2, but if tac2 finished the bullet the next action will reindent. This is a stateful process. The state is automatically reset when you get to the next proof, but if you get an error or take manual action which breaks the algorithm's expectation you can call with prefix argument to reset."

2018-12-19Put #[universes(template)] on all auto template spots in stdlibGaëtan Gilbert
2018-11-27Added two proofs to the Lists library. The first, Forall_inv_tail, extends ↵llee454@gmail.com
Forall_inv to assert that a property that is true for every element of a list is true for every element in the tail of the list. The second, Exists_impl, parallels Forall_impl and proves that if there exists an element in a list that satisfies a given predicate, and the predicate implies another proposition, then there exists an element in the list that satisfies the implied proposition. Both of these proofs fill natural gaps within the List library.
2018-11-14Deprecate hint declaration/removal with no specified databaseMaxime Dénès
Previously, hints added without a specified database where implicitly put in the "core" database, which was discouraged by the user manual (because of the lack of modularity of this approach).
