In addition to a priority, cleanup the interfaces for passing this
information as well. The pattern, if given, takes priority over the
inferred one.
We only allow Existing Instances gr ... gr | pri. for now, without
pattern, as before.
Make the API compatible to 8.5 as well.

Reporting location was not expecting a term passed to an ML tactic to
be interpreted by the ML tactic itself. Made an empirical fix to
report about the as-precise-as-possible location available.
|
|
|
|
This makes [refine] typecheck the term only once (instead of twice),
(Qed excluded of course). Fix test-suite file for output of constraints
accordingly.

Universe context not properly declared. Improve API
and code in declare.ml to allow declaration of universe contexts,
used by declaration of universes and constraints (separately).
|

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.

With this command line flag one can profile ltac in files
/and/ trim the results without actually touching the files.

Was PR#232: Fix the parsing of goal selectors.
|
|
It seems we have no grammar rule that parses floats, so I'm
parsing an integer, but the whole machinery supports floats.

Getting closer from before when the bug was introduced + test.

Previously, newlines were missing if a node had no children.
|
|
This removes a space (making the final letter of the right-aligned columns line come right before the vertical separators, rather than overlapping them), and left-aligns "tactic", as it was in Tobias' original code, which I think is easier to read. (This way, the alignment of the headers matches the alignment of the entries.)

The previous commit did not apply the beta reduction for compatibility on the
correct goal. We rather apply it on the first generated subgoal. This fixes the
ergo contrib.
|

Changes:
- data structures are purely functional (so retracting do work)
- profiling data flows towards master using the feedback bus
- master aggregates the data on printing
|
|
calls are logged too. Using appropriate printer for reparsability of
the output.
|
|
|
|
The problem came from the fact that the legacy beta-reduction occurring
after a rewrite was wrongly applied to the side-conditions of the
rewriting step. We restrict it to the correct goal in this patch.
|
|
|
|
This was an overlook. There was no reason to let it in the tactics/ folder,
as is was semantically part of the Ltac implementation.

when the rewrite lemma doesn't typecheck or does not
correspond to a relation.

It should use evar instantiations eagerly during unification of
the lhs of the lemma, as in 8.4.

We apply this patch to trunk so that it is integrated in 8.6.

This is a reimplementation of Hugo's PR#117.
We are trying to address the problem that the name of some reduction functions
was not saying what they were doing (e.g. whd_betadeltaiota was doing let-in
reduction). Like PR#117, we are careful that no function changed semantics
without changing the names. Porting existing ML code should be a matter of
renamings a few function calls.
Also, we introduce more precise reduction flags fMATCH, fFIX, fCOFIX
collectively denominated iota.
We renamed the following functions:
Closure.betadeltaiota -> Closure.all
Closure.betadeltaiotanolet -> Closure.allnolet
Reductionops.beta -> Closure.beta
Reductionops.zeta -> Closure.zeta
Reductionops.betaiota -> Closure.betaiota
Reductionops.betaiotazeta -> Closure.betaiotazeta
Reductionops.delta -> Closure.delta
Reductionops.betalet -> Closure.betazeta
Reductionops.betadelta -> Closure.betadeltazeta
Reductionops.betadeltaiota -> Closure.all
Reductionops.betadeltaiotanolet -> Closure.allnolet
Closure.no_red -> Closure.nored
Reductionops.nored -> Closure.nored
Reductionops.nf_betadeltaiota -> Reductionops.nf_all
Reductionops.whd_betadelta -> Reductionops.whd_betadeltazeta
Reductionops.whd_betadeltaiota -> Reductionops.whd_all
Reductionops.whd_betadeltaiota_nolet -> Reductionops.whd_allnolet
Reductionops.whd_betadelta_stack -> Reductionops.whd_betadeltazeta_stack
Reductionops.whd_betadeltaiota_stack -> Reductionops.whd_all_stack
Reductionops.whd_betadeltaiota_nolet_stack -> Reductionops.whd_allnolet_stack
Reductionops.whd_betadelta_state -> Reductionops.whd_betadeltazeta_state
Reductionops.whd_betadeltaiota_state -> Reductionops.whd_all_state
Reductionops.whd_betadeltaiota_nolet_state -> Reductionops.whd_allnolet_state
Reductionops.whd_eta -> Reductionops.shrink_eta
Tacmach.pf_whd_betadeltaiota -> Tacmach.pf_whd_all
Tacmach.New.pf_whd_betadeltaiota -> Tacmach.New.pf_whd_all
And removed the following ones:
Reductionops.whd_betaetalet
Reductionops.whd_betaetalet_stack
Reductionops.whd_betaetalet_state
Reductionops.whd_betadeltaeta_stack
Reductionops.whd_betadeltaeta_state
Reductionops.whd_betadeltaeta
Reductionops.whd_betadeltaiotaeta_stack
Reductionops.whd_betadeltaiotaeta_state
Reductionops.whd_betadeltaiotaeta
They were unused and having some reduction functions perform eta is confusing
as whd_all and nf_all don't do it.

This fixes some parsing problems when doing things like
[let n := 2 in idtac n]. See bug #4877.

On the user side, coqtop and coqc take a list of warning names or categories
after -w. No prefix means activate the warning, a "-" prefix means deactivate
it, and "+" means turn the warning into an error. Special categories include
"all", and "default" which contains the warnings enabled by default.
We also provide a vernacular Set Warnings which takes the same flags as argument.
Note that coqc now prints warnings.
The name and category of a warning are printed with the warning itself.
On the developer side, Feedback.msg_warning is still accessible, but the
recommended way to print a warning is in two steps:
1) create it by:
let warn_my_warning =
CWarnings.create ~name:"my-warning" ~category:"my-category"
(fun args -> Pp.strbrk ...)
2) print it by:
warn_my_warning args

using a custom feedback message in response to "Show Ltac Profile."

|
|
Doing it explicitly because it is in another file.
