changes:
-Fix negative exponential detection
-Only disable trailing zeroes option in basic mode
-Disable ambiguous multiplication with Eulers number, e.g. "2e" as this
makes exponential numbers confusing
Changes since previous release:
Compiler
- The compiler now treats ^ as alias for **.
- The compiler now rejects ambiguous left hand sides of
definitions where parameter types are left out for
inference. Previously, the compiler would pick the first
signature from some mostly random order, with a warning.
- For categories with default implementations, the compiler
can be directed to compile only the purely category part
(exports), or only the default implementations (category
packages).
- The compiler now supports a Foreign Function Interface. In
particular, signatures for external entities may be declared
at capsule level. Currently, only ISO C functions are
supported, but future releases may support ISO C++ and other
mainstream languages.
- The parsing of signature for operators has been improved.
Previously, operator names needed to be quoted in signature.
That is not longer needed. For instance, previously, one had
to write (at category level)
"*": (%,%) -> %
_/_\: (%,%) -> %
_not: % -> %
With this release of OpenAxiom and onward, one can simply write
*: (%,%) -> %
/\: (%,%) -> %
not: % -> %
which is much simpler to read, write, and much more regular.
- The compiler now supports is-case pattern matching. The new
pattern matching syntax is useful for structuring retractions,
and also for domain recovery from expressions of type Any.
- The compiler now supports the loop control transfer operator
iterate in repeat loops - previously, the construct was
accepted only in scripts (not libraries). That discrepency is
now ended.
Interpreter
- Declared variable with no specified values are now handled
as if symbolic value with a specified type.
- The interpreter now parses a disjunctive expression
involving the 'is' operator the obvious way. E.g. Now
T is Integer or T has Ring
is now understood as
(T is Integer) or (T has Ring)
- The interpreter now handles existentially quantified or
universally quantified expressions
Algebra
The following types have been added to OpenAxiom-1.3.0
- The domain Boolean and category BitAggregate no longer
export the operation ^ for logical negation. Use the
operator not which is the canonical and documented operator.
- The domain InputForm now has a new exported signature
parseString: String -> %
for parsing expressions given as string.
- The domain Boolean now belongs to the category
OrderedFinite.
- The domain KleeneTrivalentLogic is added. It implements
Stephen Kleene's 3-valued propositional logic.
- For file orinted I/O, new domains have been added:
+ IOMode: This domains defines three constants to indicate
the direction of file I/O operations.
+ InputBinaryFile: This domains implements the basic input
operations on binary files.
+ OutputBinaryFile: This domains implements the basic
output operations on binary files.
- The domain BinaryFile has been replaced by three specific domains:
+ InputBinaryFile: datatype for input file open in binary mode;
+ OutputBinaryFile: datatype for output file open in binary mode;
+ InputOutputBinaryFile: datatype for input and output file open
in binary mode.
- Three new categories are introduced, related to conversions:
+ CoercibleFrom: This category is the mirror image of the
standard category CoercibleTo.
+ HomotopicTo: This category is the symmetrization of the
category CoercibleTo.
+ ConvertibleFrom: This category is the mirror image of
ConvertibleTo.
- Previous releases defined instantiations of the domain
constructor Expression as satisfying the category OrderedSet.
That was both confusing and incorrect in conjunction with
other algebraic structures. From now on, Expression(T) no
longer satisfies OrderedSet.
- Three new categories have been added:
+ LeftLinearSet
+ RightLinearSet
+ LinearSet
The category AbelianGroup extends LeftLinearSet Integer.
The parameterized category constructor LeftModule extends
LeftLinearSet. Similarly, the category RightModule extends
RightLinearSet.
- The domain Any has been reworked. In particular, the
operation domainOf, objectOf, and showTypeInOutput have been
removed. Equality of two objects of domain Any is equality
according to the underlying domain, if that domain belongs to
the category BasicType; otherwise, it is equality of storage
locations.
Runtime System
The Lisp backend now uses type information derived from exports
and domain representation for code generation purposes.
Notable changes (compared to version 1.0.7) include:
- Improved version of guessing package. It can now handle
much larger problems than before. Added ability to guess
functional substitution (Mahler) equations.
- Experimental support for build using CMU CL.
- Various speed improvements including faster indexing for two
dimensional arrays.
- By default FriCAS build tries to use SBCL.
- Building no longer require patch.
Bug fixes, in particular:
- correct definition of random() for matrices
- conditionals in .input files work again
- Spad compiler now recognizes more types as equal
- fixed problem with pattern-matching quote
Changes from version 2.4.1 to version 2.4.2:
- Security fix in formatted output functions (buffer overflow).
- Formatted output functions: 6 is now the default value for
empty precision field with %Rf.
- Better portability of configure script.
- Detection of intmax_t and uintmax_t types.
- Improved documentation: mpfr_get_z_exp, mpfr_strtofr, mpfr_get_str and
formatted output functions.
- Improved message in case of assertion failure.
- Test coverage: 97.0% lines of code.
- Updated tcmp_ld test to really test the long double.
- Some documentation files are installed in $docdir.
- Removed mpfr_init_cache (unused and undocumented function).
- Fixed the way $CC / $CFLAGS are got from gmp.h (__GMP_CC / __GMP_CFLAGS).
- Bug fixes.
- Also note that GCC 4.4.0 (only this obsolete version) does not build
MPFR 2.4.2 correctly; this is detected by "make check" (failures in
tget_z and tpow_all).
* Package help is now converted from Rd by the R-based converters
that were first introduced in 2.9.0.
* HTML help is now generated dynamically using an HTTP server
running in the R process and listening on the loopback interface.
* polygon(), pdf() and postscript() now have a parameter
'fillOddEven' (default FALSE), which controls the mode used for
polygon fills of self-intersecting shapes.
* New debugonce() function; further,
getOption("deparse.max.lines") is now observed when debugging.
* plot() methods for "stepfun" and hence "ecdf" no longer plot
points by default for n >= 1000.
* [g]sub(*, perl=TRUE) now also supports '\E' in order to *end*
\U and \L case changes, thanks to a patch from Bill Dunlap.
* factor(), `levels<-`(), etc, now ensure that the resulting factor
levels are unique (as was always the implied intention). Factors
with duplicated levels are still constructible by low-level means,
but are now declared illegal.
* New print() (S3) method for class "function", also used for
auto-printing. Further, .Primitive functions now print and
auto-print identically.
* The print() and toLatex() methods for class "sessionInfo" now
show the locale in a nicer format and have arguments to
suppress locale information.
* In addition to previously only round(), there are other 'Math'
group (S3) methods for 'difftime', such as floor(), signif(), abs(), etc.
* For completeness, old.packages() and available.packages() allow
'type' to be specified (you could always specify 'available'
or 'contriburl').
* More...

OpenFst is a library for constructing, combining, optimizing, and
searching weighted finite-state transducers (FSTs). Weighted
finite-state transducers are automata where each transition has an
input label, an output label, and a weight. The more familiar
finite-state acceptor is represented as a transducer with each
transition's input and output label equal. Finite-state acceptors
are used to represent sets of strings (specifically, regular or
rational sets); finite-state transducers are used to represent
binary relations between pairs of strings (specifically, rational
transductions). The weights can be used to represent the cost of
taking a particular transition.
This library was developed by contributors from Google Research
and NYU's Courant Institute. It is intended to be comprehensive,
flexible, efficient and scale well to large problems. it has been
extensively tested. It is an open source project distributed under
the Apache license.
* What is new in gsl-1.13:
** Upgraded to latest autoconf and automake (autoconf-2.64,
automake-1.11)
** Fixed the rk4 and bspline allocators to avoid invalid free()
calls under out of memory conditions. [bug #27194, #27236]
** Fixed a bug in gsl_multimin_fminimizer_nmsimplex2 where the center
and size of the simplex were not updated on contract-by-best steps,
causing failures in convergence. [bug #27180]
** Added new functions to set MISER and VEGAS Monte Carlo integration
parameters, and to examine VEGAS chi-squared value and intermediate
results.
** Added the function gsl_bspline_greville_abscissa to compute
Greville abscissae for B-splines.
** The cumulative distribution functions gsl_cdf_gumbel1_{P,Q} should
now handle a larger range of parameters without underflow and
overflow.
** The header file gsl_const_cgs.h no longer defines values for
electromagnetic units. Applications should use gsl_const_cgsm.h
instead to obtain the values in the CGS-Magnetic system. The
previous values for these units given in gsl_const_cgs.h were
ill-defined as the type of CGS electromagnetic system was
unspecified (the values were a mixture of CGS units with the Ampere
of the MSKA system). The affected constants are
GSL_CONST_CGS_BOHR_MAGNETON, GSL_CONST_CGS_ELECTRON_CHARGE,
GSL_CONST_CGS_ELECTRON_MAGNETIC_MOMENT, GSL_CONST_CGS_FARADAY,
GSL_CONST_CGS_GAUSS, GSL_CONST_CGS_NUCLEAR_MAGNETON,
GSL_CONST_CGS_PROTON_MAGNETIC_MOMENT, and GSL_CONST_CGS_ROENTGEN.
** The Pochhammer functions gsl_sf_poch(a,x) and gsl_sf_lnpoch(a,x) now
handle the special cases where a and a+x are zero or negative
integers.
** The confluent hypergeometric function gsl_sf_hyperg_U (a,b,x) now
handles some cases where x=0. The case where 1+a-b is a negative
integer no longer returns an error [bug #22859] and the incorrect
termination of the series in certain cases is fixed [bug #26706].
** Added a new function gsl_poly_eval_derivs to evaluate a polynomial
and its derivatives simultaneously.
** Added a new univariate minimisation algorithm
gsl_min_fminimizer_quad_golden which is a variant of Brent's
algorithm with safeguarded step-length adjustment.
** Added a new Nelder-Mead minimiser gsl_multimin_fminimizer_nmsimplex2rand
which uses a randomly oriented simplex rather than one fixed on
the coordinate axes [bug #25077]
** The texinfo file now uses the dircategory "Software libraries" from
the Free Software Directory, as recommended in the Texinfo manual.
** The function gsl_ran_exponential now includes zero in its output
range. [bug #25039]
** All functions for freeing allocated memory now accept a NULL
pointer, following the standard C convention for free(). [bug
#25319]
** The function gsl_sum_levin_u_accel now handles the special case
c_0 + 0 + 0 + 0 + .... that occurs when summing power series
c_n*x^n with x=0. [bug #26807]
** The functions gsl_linalg_LU_solve, gsl_linalg_LU_svx,
gsl_linalg_LU_refine, gsl_linalg_LU_invert and their complex
equivalents now return an error for singular matrices.
** The multifit LMDER hybrid solvers now check the return code of the
user-supplied function in the gsl_multifit_fdfsolver_set
method. [bug #26871]
** Improved the implementation of gsl_ran_discrete_preproc to avoid
internal errors due to inconsistencies from excess precision on
some platforms. [bug #26502]
** Corrected gsl_sf_hyperg_2F1(a,b,c,x) to not give a domain error in
the case where c is a negative integer and the series terminates
with a finite result.
** The C99 inline keyword is now supported, in addition to the
previously supported GNU-style inline.
** Modified gsl_poly_complex_solve_cubic and gsl_poly_solve_cubic to
avoid returning NaNs in cases where excess precision causes a
change in the number of roots.
** Fixed incorrect length check in gsl_blas_drotm. [bug #26503]
** Fixed gsl_odeiv_step_gear2 to restore y on step failure
** gsl_odeiv_evolve_apply now restores the correct value of t on step
failures [bug #26255].
** Using make install prefix=DIR now puts correct paths in package
config files gsl-config and gsl.pc
** Modified gsl_monte_vegas to work around pow() function inaccuracies
on MinGW [bug #25413].
** Increased the number of terms in gsl_sf_mathieu_a and
gsl_sf_mathieu_b to improve convergence in difficult regions [bug
#25075]
