Log Message:
Update pure to 0.56.
Changes from previous:
----------------------
2012-11-19 Albert Graef <Dr.Graef%t-online.de@localhost>
* 0.56 release.
* configure.ac, interpreter.cc/hh: LLVM 3.2 compatibility.
2012-11-13 Albert Graef <Dr.Graef%t-online.de@localhost>
* runtime.cc (pure_str): Alternative str() implementation which
returns a Pure string instead of a raw C string. We use this in
primitives.pure now to prevent the memory leaks resulting from
calling str() directly from Pure.
* util.cc (my_strdup, my_strfree): strdup/free replacements to
reduce the number of temporary string allocations. This is still
experimental.
* interpreter.cc (compile_interface): Get rid of bogus warnings
for abstract (unimplemented) interface types.
(finalize_interface_rules): Fix detection of empty interfaces.
This fixes issue #95.
* lib/prelude.pure, lib/matrices.pure: Fixes to all, any, unzip
(cf. issue #92 and #93). Also, smatrix accepts a dimension
argument now like the other matrix construction functions
(issue #96).
* lib/primitives.pure: Improved simplifications of partially
evaluated logical connectives. E.g., both 1&&x and x&&1 give x
now.
2012-11-06 Albert Graef <Dr.Graef%t-online.de@localhost>
* texmacs: Overhaul of TeXmacs plugin.
2012-10-19 Albert Graef <Dr.Graef%t-online.de@localhost>
* runtime.cc (reduce): Fixed a memory leak and resolved a rather
obscure segfault due to global closures becoming invalidated by a
recent recompile.
2012-10-16 Albert Graef <Dr.Graef%t-online.de@localhost>
* lexer.ll: TeXmacs completion support.
2012-10-12 Albert Graef <Dr.Graef%t-online.de@localhost>
* pure.cc, lexer.ll, runtime.cc: Improved readline support: Add
secondary command input, so that the debugger has its own command
history.
2012-10-08 Albert Graef <Dr.Graef%t-online.de@localhost>
* lib/prelude.pure (n..m): Bugfix: For consistency with the
n1:n2..m case, do a quick check that m-n yields a real value (this
will fail if n and m don't belong to the same enumerated type,
in which case we want to leave n..m as a normal form).
* interpreter.cc (exec): Improvements in TeXmacs mode. The REPL
now temporarily replaces __show__ with __texmacs__ in order to
allow for custom pretty-printing of expressions in TeXmacs
mode. (Note that simply redefining __show__ may break applications
which rely on print representations returned by the `str`
function.)
2012-10-04 Albert Graef <Dr.Graef%t-online.de@localhost>
* lib/primitives.pure: Rename break, trace to __break__, __trace__
to prevent naming conflicts. While `break` isn't likely to occur
in user code, `trace` is commonly used, e.g., as a matrix
operation.
2012-10-02 Albert Graef <Dr.Graef%t-online.de@localhost>
* examples/texmacs: Added TeXmacs/LaTeX template contributed by
Kurt Pagani.
2012-09-28 Albert Graef <Dr.Graef%t-online.de@localhost>
* interpreter.cc: Use a reasonable default for the advisory stack
limit so that stack checks are always done by default.
2012-09-27 Albert Graef <Dr.Graef%t-online.de@localhost>
* examples/matrix_inversion.pure: Added matrix inversion example
by Rob Hubbard, ported from Q to Pure by Jiri Spitz.
* lexer.ll (docmd): Add -h (help) option to the del, trace and run
commands.
2012-09-26 Albert Graef <Dr.Graef%t-online.de@localhost>
* etc/*: Add new break and trace builtins to keyword tables.
* lib/primitives.pure: New break and trace builtins (see below).
* runtime.cc/h: New pure_break() and pure_trace() primitives.
These trigger debugging and tracing when called from a Pure
program with debugging enabled.
2012-09-24 Albert Graef <Dr.Graef%t-online.de@localhost>
* examples/lu.pure: Example contributed by Johannes Engels.
* interpreter.hh (interpreter), interpreter.cc (exec), lexer.ll
(lex_input), runtime.cc (pure_debug_rule), pure.cc (main): Add
minimal support for texmacs (http://www.texmacs.org/), per request
by Kurt Pagani (issue #89).
* etc/pure-mode.el.in: Add a pure-send-yank command which allows
to send lines from the kill ring to the interpreter. This works in
both pure-mode and pure-eval-mode. Also added a new
pure-send-skip-prompts flag (enabled by default). This causes the
send commands to preprocess input which looks like a session
transcript containing both command prompts and results, by
removing prompts and skipping non-command lines. This is
convenient, in particular, to send samples of interpreter
interactions from the online documentation.
2012-09-20 Albert Graef <Dr.Graef%t-online.de@localhost>
* lib/prelude.pure, lib/primitives.pure: Declare 'true' and
'false' as nonfix symbols so that they can be used in patterns.
Also add a 'bool' type along with a corresponding 'boolp'
predicate for normalized truth values (0 and 1), and a 'bool'
function to convert machine integers to normalized truth values.
2012-09-11 Albert Graef <Dr.Graef%t-online.de@localhost>
* lib/prelude.pure: Adjust the __do__ macro for generator clauses
involving patterns (see below).
* interpreter.cc (mklistcomp_expr, mkmatcomp_expr): Add the
necessary magic to make comprehensions involving patterns filter
out unmatched generator values automatically, as it is in Haskell.
2012-09-07 Albert Graef <Dr.Graef%t-online.de@localhost>
* lib/enum.pure: New enum.pure module which provides some
convenience functions to facilitate the creation of enumeration
types. Experimental.
2012-09-06 Albert Graef <Dr.Graef%t-online.de@localhost>
* lib/prelude.pure (..): Fix some glitches in the generic
arithmetic sequences with step size, so that they work with
general enumerated types.
2012-09-05 Albert Graef <Dr.Graef%t-online.de@localhost>
* pure.cc (main): Spiffy new logo for the sign-on message. You can
disable this with the --plain option or by setting the PURE_PLAIN
environment variable, if you prefer the old sign-on message.
2012-08-22 Albert Graef <Dr.Graef%t-online.de@localhost>
* parser.yy: Uncaught exceptions of mklistcomp_expr/mkmatcomp_expr
in parser (fixes issue #88 reported by kp%scios.ch@localhost).
2012-08-15 Albert Graef <Dr.Graef%t-online.de@localhost>
* lexer.ll: Cosmetic changes to the parsing of special command
syntax (fixes issue #84).
2012-08-14 Albert Graef <Dr.Graef%t-online.de@localhost>
* interpreter.cc (build_map): 'case' needs a separate FMap root
for each rule so that the call to FMap::select() in try_rules()
does the right thing (fixes issue #87 reported by Jim Pryor).
2012-07-17 Albert Graef <Dr.Graef%t-online.de@localhost>
* interpreter.cc/hh, runtime.cc, pure.cc, lexer.ll: Integrated a
patch by Jim Pryor (with modifications) which allows the escape
mode command prefix to be specified with the --escape option and
the PURE_ESCAPE environment variable. Thanks Jim!
2012-07-16 Albert Graef <Dr.Graef%t-online.de@localhost>
* printer.cc (printx): Bugfix in pretty-printer: Type tags must be
padded with whitespace if compile time expressions are printed
with deBruijn annotations (-v2). Otherwise the pretty-printed code
won't be reparsed correctly, since x/*...*/::y will be parsed as
x ::y rather than x :: y.
This bug affected, in particular, test/special.pure. Many of the
other golden test logs were also updated accordingly.
2012-07-06 Albert Graef <Dr.Graef%t-online.de@localhost>
* lexer.ll, parser.yy, interpreter.cc/hh, symtable.cc/hh:
Implemented namespace brackets, based on an idea by Yann Orlarey.
This makes it much more convenient to use embedded domain-specific
sublanguages in Pure. For instance, you may now write something
like:
outfix « »;
namespace faust (« »);
This means that the namespace 'faust' can now be accessed on the
fly in expressions like «(a,b,c) : (sin,cos,tan)». The
subexpression inside the namespace brackets is then parsed by
temporarily switching to the corresponding namespace. The
namespace brackets themselves must be a pair of outfix symbols
which has been declared already, and are removed from the
resulting expression. This works pretty much like a 'namespace'
declaration, but only gives access to the public symbols of the
namespace, and can be used anywhere inside an expression (even on
the left-hand side of a rule). Nesting these constructs is also
possible.
Also, to accommodate these changes, the declaration syntax is now
slightly more liberal in that qualified symbols are permitted in
symbol and namespace declarations. (In the case of symbol and
'using namespace' declarations, it will also be checked that
qualified symbols are declared in or imported from the proper
namespace.) This allows you to write stuff like:
namespace faust with outfix faust::begin faust::end; end;
namespace faust (faust::begin faust::end);
which isn't possible without using namespace qualifiers because
'end' by itself is a reserved keyword in Pure.
2012-06-28 Albert Graef <Dr.Graef%t-online.de@localhost>
* lexer.ll (docmd): Bugfixes and improvements in the interactive
command parser. In particular, clear, dump and show will now
complain about undefined symbols. This doesn't detect unmatched
glob patterns and so isn't 100% foolproof, but it should catch
most common errors and typos.
2012-06-27 Albert Graef <Dr.Graef%t-online.de@localhost>
* pure.cc: Add -e/--escape option and PURE_ESCAPE environment
variable to switch on new escaped command syntax. Also fix up
command completion accordingly.
* lexer.ll, interpreter.cc/hh: Add support for escaped command
syntax, as discussed on the mailing list. If this option is
enabled, all interactive commands are prefixed with '!'. (This
only applies to the command line, evalcmd works as before.)
2012-06-26 Albert Graef <Dr.Graef%t-online.de@localhost>
* examples/msort.pure: Added merge sort example by Jim Pryor.
* configure.ac: Bump version number.
* interpreter.cc (macspecial), symtable.cc/hh: Add a new built-in
__gensym__ macro, per request by Jim Pryor. This enables you to
create new, unqualified symbols on the fly, which is useful if a
macro needs to generate block constructs such as lambdas and
when/with clauses from scratch.
2012-06-25 Albert Graef <Dr.Graef%t-online.de@localhost>
* lib/matrices.pure: Experimental: As suggested by Jim Pryor, add
non-splicing vector brackets as a shorthand notation for nested
vectors.
* runtime.cc (hash): Include environment in closure hashes (fixes
second part of issue #82).
2012-06-24 Albert Graef <Dr.Graef%t-online.de@localhost>
* examples/do.pure: Add __do__ macro example from the Macros
section of the manual.
* runtime.cc (hash): Bogus assertion for anonymous closure (fixes
issue #82 reported by Jim Pryor).
2012-06-20 Albert Graef <Dr.Graef%t-online.de@localhost>
* etc/pure.ssh: Added Eddie Rucker's a2ps style sheet for Pure.
2012-06-17 Albert Graef <Dr.Graef%t-online.de@localhost>
* interpreter.cc (quoted_tag): Missing "as" pattern in quoted
pattern (fixes issue #79 reported by Jim Pryor).
2012-06-16 Albert Graef <Dr.Graef%t-online.de@localhost>
* interpreter.cc (macspecial): Leave the cases of __lambda__,
__case__, __when__ and __with__ with an empty list argument
undefined by the built-in macro rules (fixes issue #78 reported by
Jim Pryor).
* interpreter.cc (const_defn, clearsym): Make sure that we
allocate a fresh expression pointer for each constant value cached
in a read-only variable. This will leak a tiny amount of memory
each time such a constant is redefined (which is possible using
interactive commands and the introspection facilities), but this
is needed to keep any dangling references to the constant intact.
This fixes issue #77.
2012-06-15 Albert Graef <Dr.Graef%t-online.de@localhost>
* runtime.cc (get_funptr): get_funptr() might be invoked after a
function was already purged from the environment.
2012-06-14 Albert Graef <Dr.Graef%t-online.de@localhost>
* interpreter.cc (checkfuns): Remove bogus assertion (issue #75).
(next_statem): Missing case in code generation for matrix matching
(issue #76). Reported by Jim Pryor.
2012-06-04 Albert Graef <Dr.Graef%t-online.de@localhost>
* 0.55 release.
* interpreter.cc: Make clang and gfortran -fdragonegg the default
compilers for inlined C/C++/Fortran code, as llvm-gcc isn't
supported in the LLVM 3.x series any more.
2012-06-03 Albert Graef <Dr.Graef%t-online.de@localhost>
* configure.ac: Bump version number.
* configure.ac, interpreter.cc: Add some options to deal with
systems such as Mac OSX and Ubuntu which may have the LLVM
toolchain and configure script installed under different prefixes,
so that several LLVM versions can coexist on the same system.
First, the configure option --with-tool-prefix allows to specify
the prefix for the LLVM toolchain. This option, if specified, is
also used to locate the llvm-config script, so that the proper
LLVM version is selected.
Second, the --with-llvm-version option allows to set the desired
LLVM version, in which case configure tries to locate the
llvm-config-<version> script on the PATH (after trying the tool
prefix, if specified). If this option isn't specified, we default
to looking for the llvm-config script on the PATH, which matches
the behaviour in previous releases.
If none of these yield a usable llvm-config script, we fall back
to trying llvm-config-<version> for recent LLVM versions,
preferring the latest version if found. Otherwise we give up and
print an error message.
2012-06-02 Albert Graef <Dr.Graef%t-online.de@localhost>
* interpreter.cc/hh: Bugfix in type name resolution. Reported by
Lucas Paul. Fixes issue #71.
2012-05-22 Albert Graef <Dr.Graef%t-online.de@localhost>
* Debian support: Add Debian packaging and a corresponding goal in
the Makefile.
2012-05-19 Albert Graef <Dr.Graef%t-online.de@localhost>
* 0.54 release.
* interpreter.cc (funsubstw): Fix clobbering of qualified symbols
in the global namespace.
2012-05-15 Albert Graef <Dr.Graef%t-online.de@localhost>
* lib/prelude.pure: Fix up regression in optimization rules for
list slices introduced in Pure 0.49. Reported by Yann Le Du.
2012-05-09 Albert Graef <Dr.Graef%t-online.de@localhost>
* configure.ac: Version bump.
* interpreter.cc/hh, runtime.cc, pure.cc: LLVM 3.1 compatibility
fixes.
2012-03-22 Albert Graef <Dr.Graef%t-online.de@localhost>
* 0.53 release.
* runtime.cc (pure_sort): As suggested by Peter Summerland,
optimize the case of POD types (int, bigint, double, string) in
conjunction with the standard (<) and (>) predicates. In this case
we don't actually have to invoke the Pure predicates, but can just
execute the comparisons directly in C++. With int lists this gives
a 10x speedup.
2012-03-08 Albert Graef <Dr.Graef%t-online.de@localhost>
* lexer.ll: Add -r and -s options to the trace command to switch
between the new recursive and the previous skip tracing mode (see
below).
* interpreter.cc/hh, runtime.cc: Fix up function and macro call
tracing to allow for recursive tracing of reductions while a
tracepoint was invoked. Make this the default, as it's more useful
in most situations.
2012-03-08 Albert Graef <Dr.Graef%t-online.de@localhost>
* 0.52 release.
* lexer.ll (docmd): Add a -a option to the trace command which
sets tracepoints on all (global) symbols.
2012-03-06 Albert Graef <Dr.Graef%t-online.de@localhost>
* Makefile.in: Fix a glitch causing discrepancies between
generated log and actual test log for the prelude.
* lib/prelude.pure: Fix up the definition of the __do__ macro for
the reworked treatment of macro arguments.
* interpreter.cc/hh, lexer.ll: Fixed some of the bad side-effects
of autoquoting of macro arguments which would break macro hygiene.
Implicit quoting of macro arguments is now disabled by default,
and can be selectively enabled for individual macros with the new
--quoteargs pragma. Also, autoquoted macro parameters are now
actually quoted, i.e., embedded macro calls are not evaluated.
This fixes name capture issues due to premature evaluation of
embedded macros in quoted macro arguments. One minor defect which
remains is the case of a free variable in a macro substition being
captured by a local definition if the entire construct is quoted;
see the last example in test078.pure. (One might argue, though,
that in this specific case the behaviour of the macro evaluator is
actually correct.)
2012-03-02 Albert Graef <Dr.Graef%t-online.de@localhost>
* runtime.cc: Update for the latest Faust revision after cleanup
of the Faust UI data structures.
2012-02-20 Albert Graef <Dr.Graef%t-online.de@localhost>
* interpreter.cc (lcsubst): Added a missing recursion in the
conditional, lambda, case, when and with cases. This fixes a
failed assertion in the bind() method which could also occur, in
particular, when processing comprehensions on the left-hand side
of an equation or lambda. Reported by Richard Grossman.
2012-01-05 Albert Graef <Dr.Graef%t-online.de@localhost>
* parser.yy: Refactor some grammar rules so that some types of
syntax errors in toplevel constructs are caught a bit earlier (see
issue #69 reported by Jiri Spitz).
