* | Fix bug #5098: Symmetry broken in HoTT.Gravatar Pierre-Marie Pédrot2016-10-08
| | | | | | | | | | | | | | We defactorize the in_clause grammar entry to allow parsing of the "symmetry" tactic when it has no arguments. Beforehand, the clause_dft_concl entry accepted the empty stream, preventing the definition of symmetry as a mere identifier.
* | Fix bug #4464: "Anomaly: variable H' unbound. Please report.".Gravatar Pierre-Marie Pédrot2016-10-07
| | | | | | | | | | | | We simply catch the RetypeError raised by the retyping function and translate it into a user error, so that it is captured by the tactic monad instead of reaching toplevel.

* | Do not add "Append" as a lexer keyword.Gravatar Pierre-Marie Pédrot2016-10-06
| | | | | | | | | | | | | | This was introduced to implement the Append feature on options. As usual when messing with predefined keywords, this broke code in the wild. In order not to create a new keyword, we do the string analysis on the production branch of parsing.
* | Disable compatibility notations warnings.Gravatar Maxime Dénès2016-10-06
| | | | | | | | | | | | | | | | | | | | Enablnig them would give a system that tells the user to replace e.g.: le_n_Sn with Nat.le_succ_diag_r lt_S with Nat.lt_lt_succ_r (on other types like R and and positive, the same lemma is called lt_lt_succ) In many cases, the new names will be too painful for intensive users.
| * evarconv.ml: Fix bug #4529, primproj unfoldingGravatar Matthieu Sozeau2016-10-06
| | | | | | | | | | Evarconv was made precociously dependent on user-declared reduction behaviors. Only cbn should rely on that.

* | Remove the -no-compat-notations flag.Gravatar Maxime Dénès2016-10-06
| | | | | | | | | | | | This option was not doing anything... Today, one can turn the compatibility notations warning into an error, if ever that was the intended semantics.
* | Remove the Set Verbose Compat option and turn the warning on by default.Gravatar Maxime Dénès2016-10-06
| | | | | | | | | | These warnings can now be configured like any other, so we don't need a specific option anymore.
| * unification.ml: fix for bug #4763, unif regressionGravatar Matthieu Sozeau2016-10-06
| | | | | | | | | | | | | | Do not force all remaining conversions problems to be solved after the _first_ solution of an evar, but only at the end of assignment of terms to evars in w_merge. This was hell to track down, thanks for the help of Maxime. contribs pass and HoTT too.

* | Fix a bug of Mltop.declare_cache_object.Gravatar Pierre-Marie Pédrot2016-10-05
| | | | | | | | | | | | | | Objects registered through the callback functions were pushed on the libstack before the ML-MODULE object itself, leading to anomalies when the corresponding object was assuming that the ML module was properly defined in any other Coq module requiring the Declare ML command.

* | Fix #5048 - Casts in pattern raise an anomaly in Constrintern.Gravatar Maxime Dénès2016-10-04
| | | | | | | | | | | | | | | | We protect the code against the presence of pattern casts where they are not supported. Why we cannot make the pattern type reflect this is a long story (described in this commit), but in the long term we probably want to support them anywhere, like OCaml does. Of course, it will require to adjust the pattern matching compiler.
* | Quick fix to #4595 (making notations containing "ltac:" unused for printing).Gravatar Hugo Herbelin2016-10-04

* | Changing the separator for appended string options to comma.Gravatar Maxime Dénès2016-10-04
| | | | | | | | | | | | This is a bit ad-hoc, but looks better for warnings since there is a command-line flag accepting the same values, so comma will lead to fewer parsing issues than space.

* | | | Move bullet detection from lexer to parser (bug #5102).Gravatar Guillaume Melquiond2016-10-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | That way, bullet detection no longer depends on a global variable indicating whether a line is starting. This causes a small change in the recognized language. Before the commit, "--++" was recognized as a bullet "--" followed by a keyword "++" when at the start of a line; now it is always recognized as a keyword "--++". This also fixes a bug in Tok.to_string as a side-effect.

| | | | | | | | | | | | | | | | | | | | | | | | The patch is quite dumb: it essentially consists in alpha-renaming bound module names when printing a functor, by checking that the name was not already present, and generating a fresh one otherwise.
* | | | Speed up the Search commands.Gravatar Guillaume Melquiond2016-10-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The blacklist set was converted into a string list for each item in the environment during a search. In fact, the blacklist was checked for each item, even if the item was already known to be ultimately discarded. This commit fixes both performance issues. First, blacklist_filter is no longer used directly but in two stages. Second, the boolean values are no longer computed before calling the shortcutting operators. It seems like someone had already noticed part of the second issue, since some (but not all) of the boolean values were lazily computed. The speed up becomes noticeable when the blacklist set contains more than four elements.

| | | * Add command 'Set foo Append "bar"' for appending to an option (bug #5109).Gravatar Guillaume Melquiond2016-10-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For now, the only meaningful user is "Set Warnings". Example: Section Bar. Local Set Warnings Append "-foo". (* warning foo is now disabled *) End Bar. (* foo is now reenabled, assuming it was before entering the section *)
| | | * Allow appending to string options.Gravatar Guillaume Melquiond2016-10-01
| |_|/ |/| | | | | | | | | | | | | | | | | Whether an option should be set or appended to is stored as a 2-value flag next to the new content. This commit also cleans the code by declaring a single object for each persistent option rather than three different ones (one per locality).

| | | | | | | | | | | | | | | | | | This bug was introduced by 37ab45726, because the new apply_type function was not checking that the new goal was indeed well-typed. We add this check locally in the generalize dependent tactic.
