Keep Numeral Notation wit a deprecation warning.
|
|
We add hexadecimal numerals according to the following regexp
0[xX][0-9a-fA-F][0-9a-fA-F_]*(\.[0-9a-fA-F_]+)?([pP][+-]?[0-9][0-9_]*)?
This is unfortunately a rather large commit. I suggest reading it in
the following order:
* test-suite/output/ZSyntax.{v,out} new test
* test-suite/output/Int63Syntax.{v,out} ''
* test-suite/output/QArithSyntax.{v,out} ''
* test-suite/output/RealSyntax.{v,out} ''
* test-suite/output/FloatSyntax.{v,out} ''
* interp/numTok.ml{i,} extending numeral tokens
* theories/Init/Hexadecimal.v adaptation of Decimal.v
for the new hexadecimal Numeral Notation
* theories/Init/Numeral.v new interface for Numeral Notation (basically,
a numeral is either a decimal or an hexadecimal)
* theories/Init/Nat.v add hexadecimal numeral notation to nat
* theories/PArith/BinPosDef.v '' positive
* theories/ZArith/BinIntDef.v '' Z
* theories/NArith/BinNatDef.v '' N
* theories/QArith/QArith_base.v '' Q
* interp/notation.ml{i,} adapting implementation of numeral notations
* plugins/syntax/numeral.ml ''
* plugins/syntax/r_syntax.ml adapt parser for real numbers
* plugins/syntax/float_syntax.ml adapt parser for primitive floats
* theories/Init/Prelude.v register parser for nat
* adapting the test-suite (test-suite/output/NumeralNotations.{v,out}
and test-suite/output/SearchPattern.out)
* remaining ml files (interp/constrex{tern,pr_ops}.ml where two open
had to be permuted)

Four types of numerals are introduced:
- positive natural numbers (may include "_", e.g. to separate thousands, and leading 0)
- integer numbers (may start with a minus sign)
- positive numbers with mantisse and signed exponent
- signed numbers with mantisse and signed exponent
In passing, we clarify that the lexer parses only positive numerals,
but the numeral interpreters may accept signed numerals.
Several improvements and fixes come from Pierre Roux. See
https://github.com/coq/coq/pull/11703 for details. Thanks to him.

This governs the printing of the explicitation of implicit arguments
and the removal of coercions.
E.g., "Check coe foo." where coe is a coercion with codomain B will show:
foo
: B
instead of
coe foo
: B

Async causes output reordering in one test. Since we don't care about
the output of that test (it's just a [Fail]) we move it to success/.
