pkgsrc/lang/ecl: Makefile PLIST distinfo options.mk
Update to ECL 12.2.1
* Bugs fixed:
- Fixed several dozens of typos.
- ENSURE-DIRECTORIES-EXIST did not work properly with logical pathnames.
- EXT:SET-LIMIT with option EXT:FRAME-STACK corrupted the frame stack.
- The array of boot-time symbols is fixed and independent of the features
that are compiled in. This is essential for cross-compilation and also
for sharing C code among different builds.
- Fixed externalization of bytecodes with literals that need MAKE-LOAD-FORM.
- When parsing a floating point number at least one digit should be
present. ECL parsed +.e0 as +0.0e0, instead of as a symbol.
- For OS X Lion we need a newer version of the garbage collector. Since the
maintainers' advise is that we use the unstable tree, we have made a copy
and use it _only_ for this port (src/gc-unstable).
* Visible changes:
- When printing error messages, the condition type is shown (M. Mondor)
- SI:TOP-LEVEL, when invoked without arguments, does not process the
- The command line used by EXT:PROCESS-COMMAND-ARGS is now by default
the one stored in *COMMAND-ARGS*, and this may be "cleared" by the
- SOCKET-MAKE-STREAM now accepts an :ELEMENT-TYPE argument.
- When --enable-rpath is used in combination with --with-gmp-prefix, then the
path of the GMP library is hardcoded into ECL. If the remaining libraries
(GC, libffi) are in a similar location this will make ECL work without
further flags, and without modifying LD_LIBRARY_PATH or DYLD_LIBRARY_PATH.
- All arguments after the '--' command line option are stored in a global
- In the rules passed to ext:process-command-args, :stop now implies that all
remaining arguments including the current one are collected and passed to
the rule code. An example of use of this option
;; Collect all arguments _after_ the command line option --
("--" 1 (setf ext:*unprocessed-ecl-command-args* (rest 1)) :stop)
;; Collect all arguments including the first unknown one
("*DEFAULTS*" 1 (setf ext:*unprocessed-ecl-command-args* 1) :stop)
- ECL will always build, by default, with support for Unicode strings.
- EXT:GETENV coerces its input argument to type BASE-STRING.
- The garbage collector would reset the counters on every call to
SI:GC-STATS. This made nested TIME calls not to work, as the statistics of
the inner call would spoil those of the outer one. This has been fixed.
- ECL implements CDR 6 (ext:*inspector-hook*) as described in
- ECL implements CDR 5 (Sub-interval Numerical Types) as described in
- ECL ships libffi together with its source tree, much like GMP and GC.
- On POSIX platforms ECL traps SIGCHLD and uses it to update the status of
- DIRECTORY accepts the keyword argument :RESOLVE-SYMLINKS.
- Compiling files now generates C headers with the extension "eclh". This
is done to avoid accidentally generating header files with the same name
as those in the C library. Take for instance, float.lsp -> float.h.
- ECL no longer relies on "git" being installed to gather the git commit id
and setting (ext:lisp-implementation-vcs-id).
- When building shared and statically linked libraries, ECL creates an
extra function that performs two tasks: initializing ECL if it wasn't done
before, and initializing the library. This can be used to create standalone
libraries to be linked with other programs. The name of the function
begins with main_dll or main_lib but it is output by ECL on screen.
- Hash tables do no longer have implicit locking. All complex structures in
ECL (arrays, hash tables, objects) should be dealt with sufficient care on
the user side, just as in other programming languages, making use of
WITH-LOCK and similar facilities.
- In OPEN the default format is :UTF-8 for Unicode builds and :LATIN-1 for
others, and the stream element type is always CHARACTER by default.
- Function read_VV is renamed to ecl_init_module()
- Initialization of random number generator is done using only 16 bytes from
/dev/urandom (Phillip Marek).
- Each thread keeps a copy of the process sigmask (POSIX) and it is inherited
by children thread. The sigmask can be manipulated by the function
EXT:CATCH-SIGNAL which has the signature
(ext:catch-signal signal-code action &key process)
The ACTION is one of :IGNORE, :DEFAULT, :CATCH, determining what ECL does
when it receives the signal, or it can be :MASK/:UNMASK to determine whether
the process is blocking the signal or not. The optional argument :PROCESS
only applies to :MASK/:UNMASK and it can be the current process, some
process that has not been activated or any other value (indicating that
the function has a global effect, as sigprocmask).
- Allocate executable memory using libffi instead of using just the
Boehm-Weiser garbage collector.
- In bytecodes.h, deactivate the threaded interpreter when using the LLVM
compiler. The problem is that llvm-gcc disguises itself as GCC but it is
not capable of properly compiling the jump table.
- Implemented SEQUENCE-STREAMs, which are input/output streams defined on some
specialized array type. The functions to create them are
(ext:make-sequence-input-stream vector &key :start :end :external-format)
(ext:make-sequence-output-stream vector &key :external-format)
* If the array is a string, it is a character stream.
- When no external format is supplied, it defaults to the usual
and the stream behaves like a string stream.
- When an external format is supplied, each character in the string
is interpreted as a single byte and used for that external format.
* If the array is specialized over integers and EXTERNAL-FORMAT is NIL
the stream is a binary stream.
* Otherwise, it is a binary string but READ/WRITE-CHAR may be used on
Reading and writing does not preserve the original word size of the array
but rather threads the array as a collection of bytes (octets), writing
sequentially over it. Thus, if you use encodings such as UCS2 and UCS4, make
sure that you choose the right endianness to match the shape of the array.
- DELETE-FILE works on empty directories.
- In DIRECTORY, :RESOLVE-SYMLINKS defaults to T.
- Added POSIX function (EXT:CHMOD filename mode)
- ECL's compiler is now less verbose and hides performance notes, as well as
invocations of the C compiler. This can be modfied by changing the type
specifier in c:*suppress-compiler-messages*.
- Hash tables can now be printed readably when *READ-EVAL* is true. This is
done using two new functions, EXT:HASH-TABLE-CONTENT and
- When a compiler macro fails, ECL simply ignores the errors and
continues. This is more to the spirit of the compiler macros, as explained
- INLINE declarations now actually cause the function to be inlined. If
the function is also proclaimed as INLINE, ECL will store a copy of its
definition for later use _in other files_. Otherwise INLINE declarations
remain local to the file being processed.
- ECL now implements weak hash tables. They are built as ordinary hash tables
with an extra argument, :WEAKNESS, which may be :KEY, :VALUE,
:KEY-AND-VALUE, or NIL, for the default behavior. The status of the hash
table is returned by EXT:HASH-TABLE-WEAKNESS. Note that these associations
are no substitute for proper management of resources, as the time of
collection can not be guaranteed.
- In pathnames, ".." is translated to :UP, not :BACK.
- ECL introduces two special forms, EXT:CHECKED-VALUE and EXT:TRULY-THE, which
have the same syntax as THE, but in the first case lead to a type assertion
at low safety levels and in the second case lead to an unchecked
declaration. By default THE maps to EXT:CHECKED-VALUE (as in SBCL), but this
may be controlled globally using the declaration/proclamation
- Unicode strings were not properly saved in C compiled code.
