Quoting last commit:

didn't need to be guessed, but could be deduced by "simple" higher-order
unification, the one where unifying `?f ?a` against `g args last_arg` sets `?f =
g args`.https://gitlab.mpi-sws.org/iris/stdpp/-/merge_requests/140Add notation `wn` of weakly normalizing terms; and prove some common theorems about it.2020-04-07T21:20:36ZRobbert KrebbersAdd notation `wn` of weakly normalizing terms; and prove some common theorems about it.Most important common theorem: strongly normalizing → weakly normalizing.Most important common theorem: strongly normalizing → weakly normalizing.https://gitlab.mpi-sws.org/iris/stdpp/-/merge_requests/143Add tests for equiv notation2020-04-10T05:58:08ZPaolo G.

@msammler and I figured out how to change the imports to fix this problem without the hack. Basically, `stdpp.base` exports `Coq.Strings` and `Coq.List` in the right order, so the shadowing is done right. As a consequence `Coq.Strings` should never be exported by hand.
This approach seems to work among all supported Coq versions.
We also added a test.https://gitlab.mpi-sws.org/iris/stdpp/-/merge_requests/144Another try at removing strings.length2020-04-11T09:32:46ZMichael SammlerAnother try at removing strings.lengthSee discussion in https://gitlab.mpi-sws.org/iris/stdpp/-/merge_requests/129

The idea of this version is to have two notations, one which shadows the bad definition `Strings.length` and the other which shadows the bad Notation `List.length`, which is bad because it is parsing only.https://gitlab.mpi-sws.org/iris/stdpp/-/merge_requests/145Add `encode_Z` function to encode element of countable type as `Z`.2020-04-11T10:35:24ZRobbert KrebbersAdd `encode_Z` function to encode element of countable type as `Z`.https://gitlab.mpi-sws.org/iris/stdpp/-/merge_requests/141Extracted list_numbers.v with seq, seqZ, sum_list and max_list2020-04-15T10:44:28ZMichael SammlerExtracted list_numbers.v with seq, seqZ, sum_list and max_listThis is in preparation for adding the `rotate` functions.This is in preparation for adding the `rotate` functions.https://gitlab.mpi-sws.org/iris/stdpp/-/merge_requests/146Add `ProofIrrel ()`2020-04-16T14:00:35ZPaolo G.

when creating a hint database without discrimination, Coq uses the
legacy implementation, which only uses Discrimination Trees for goals
without evars and does not use opaqueness information. This commit
switches the hint databases of stdpp to the new implementation.https://gitlab.mpi-sws.org/iris/stdpp/-/merge_requests/151fix imap_seq and imap_seq0 to make them useful2020-04-23T12:57:45ZMichael Sammlerfix imap_seq and imap_seq0 to make them usefulI think I made a mistake when I originally upstreamed these lemmas.

I very much dislike the statement of `list_find_insert_Some`, but I cannot come up with anything better that is true.https://gitlab.mpi-sws.org/iris/stdpp/-/merge_requests/155Add Countable instances for byte2020-05-12T17:53:49ZTej Chajedtchajed@gmail.comAdd Countable instances for bytehttps://gitlab.mpi-sws.org/iris/stdpp/-/merge_requests/160Revert "Merge branch 'byte-countable' into 'master'"2020-05-12T17:33:24ZRobbert KrebbersRevert "Merge branch 'byte-countable' into 'master'"This reverts merge request !155 because it's incompatible with Coq ≤8.9.This reverts merge request !155 because it's incompatible with Coq ≤8.9.
