2003-12-11 Frode Vatvedt Fjeld <frodef@cs.uit.no>
* RELEASE: 0.90
* API CHANGE! Map-binary-write functions now receive two
arguments: The object (as before), and the name of the binary-type
the object is supposed to be mapped to.
* Imroved README a bit. Documented :map-binary-read and
:map-binary-read-delayed.
* Fixed bug as reported by Simon Leinen. Various minor
bug-fixes. Changed the defpackage form to use gensym names.
2001-08-28 Frode Vatvedt Fjeld <frodef@acm.org>
* binary-types.lisp:
Added utility functions SPLIT-BYTES and MERGE-BYTES that deals with
converting lists of bytes to new byte-sizes.
2001-08-27 Frode Vatvedt Fjeld <frodef@acm.org>
* binary-types.lisp: Added generic function READ-BINARY-RECORD so
that it may be specialized.
2001-08-27 Frode Vatvedt Fjeld <frodef@acm.org>
* binary-types.lisp:
Added function ENUM-SYMBOLIC-VALUE, the inverse of ENUM-VALUE.
2001-08-27 Frode Vatvedt Fjeld <frodef@acm.org>
* binary-types.lisp: Added :binary-tags slot-option. The argument
specifies a list of "tags" (intended to be symbols, but any lisp
objects will do) that will be associated with the slot. The
function BINARY-SLOT-TAGS will retrieve the set of tags for a
slot. The function BINARY-RECORD-SLOT-NAMES has been modified to
take the keyword argument :MATCH-TAGS so that only slots with at
least one of those tags are returned.
The idea is that sometimes you need to iterate over a sub-set of
the slots, in which case a tag can be used to name and reference
such sub-sets.
2001-08-24 Frode Vatvedt Fjeld <frodef@acm.org>
* binary-types.lisp: Changed they expansion function of
DEFINE-BINARY-CLASS not to generate literal structure
objects. Expansions should be much "nicer" for the compiler to
handle now.
2001-08-17 Frode Vatvedt Fjeld <frodef@acm.org>
* binary-types.lisp: Added slot-options :MAP-ON-READ and
:MAP-ON-READ-DELAYED. The former is analogous to :MAP-ON-WRITE,
i.e. at BINARY-READ-time the function named is applied to the
(binary) value read, and the result is placed in the
slot.
:MAP-ON-READ-DELAYED is a variation that delays the mapping
operation until the slot is read. Until that time, the slot is
unbound and the binary value kept in a "hidden" slot. [This is
implemented more or less seamlessly by specializing the
SLOT-UNBOUND method.] However, the "hidden" binary value can be
read using BINARY-SLOT-VALUE; this will not cause the mapping to
occur. The idea is that if you have slots that represent pointers
to other records, you probalby don't want the READ-BINARY
operation to automatically follow and recursively read such
pointers. Using this mechanism, objects referenced by pointers
will magically be loaded "on demand".
2001-07-27 Frode Vatvedt Fjeld <frodef@acm.org>
* binary-types.lisp:
Removed LET from DEFINE-BINARY-STRUCT expansion, making it a proper top-level-form.
2001-07-27 Frode Vatvedt Fjeld <frodef@acm.org>
* RELEASE: 0.84
* binary-types.lisp: Removed (superfluous) LET* from
DEFINE-BINARY-STRUCT's expansion, so as not to hinder such forms
from being proper top-level forms.
2001-07-12 Frode Vatvedt Fjeld <frodef@acm.org>
* RELEASE: 0.83
* binary-types.lisp: Fixed READ-BINARY-STRING to work correctly
for :SIZE 0. It will now return "" and 0, rather than entering
an infinite loop.
2001-06-29 Frode Vatvedt Fjeld <frodef@acm.org>
* RELEASE: 0.82
* binary-types.lisp: Added macro WITH-BINARY-OUTPUT-TO-VECTOR.
Supposed to resemble CL:WITH-OUTPUT-TO-STRING.
2001-06-26 Frode Vatvedt Fjeld <frodef@acm.org>
* binary-types.lisp: Fixed buggy function READ-BINARY-STRING.
2001-06-22 Frode Vatvedt Fjeld <frodef@acm.org>
* binary-types.lisp: Renamed many identifiers from xx-COMPUND-xx
to xx-RECORD-xx. Of the exported symbols, only two are changed:
WRITE-BINARY-RECORD, and BINARY-RECORD-SLOT-NAMES. A (binary)
record is either a lisp struct or class.
* RELEASE: 0.81
* binary-types.lisp: Minor fixups to make BT work with CLISP.
2001-06-20 Frode Vatvedt Fjeld <frodef@acm.org>
* RELEASE: 0.80
* binary-types.lisp: Rewrote and renamed some the binary string
types. Macros DEFINE-BINARY-STRING and
DEFINE-NULL-TERMINATED-STRING should now be used to define string
types.
* binary-types.lisp: Added function READ-BINARY-STRING that should
be general enough to read most kinds of strings. It still doesn't
do character sets, though.
* binary-types.lisp: Removed traces of variable-sized binary
types. Everything is now constant-sized. Removed functions
SIZEOF-MIN and SIZEOF-MAX.
2001-06-09 Frode Vatvedt Fjeld <frodef@acm.org>
* binary-types.lisp: Removed one more instance of upcased symbols
in the code, in order to facilitate those using case-sensitive
readers.
2001-06-06 Frode Vatvedt Fjeld <frodef@acm.org>
* RELEASE: 0.76
* binary-types.lisp: Added macro WITH-BINARY-INPUT-FROM-VECTOR.
* binary-types.lisp: Added check for end-of-list in
WITH-BINARY-INPUT-FROM-LIST macro.
* Makefile: Forgot to include recently added file
type-hierarchy.ps in the distribution tarball.
2001-05-03 Frode Vatvedt Fjeld <frodef@acm.org>
* binary-types.lisp: Renamed the slot-options (the old ones still
work though).
:bt => :binary-type
:btt => :binary-lisp-type
:bt-on-write => :map-binary-write.
* binary-types.lisp: Added a pseudo-type :LABEL available only
inside DEFINE-BINARY-CLASS and which is a void type intended for
"slots" that don't hold any data but are used as labels in the
struct in order to determine offsets etc. If this type is declared
with the :btt (or :binary-lisp-type) slot-option, the lisp :type
NIL is declared (the empty type).
2001-04-24 Frode Vatvedt Fjeld <frodef@acm.org>
* RELEASE: 0.75
2001-04-23 Frode Vatvedt Fjeld <frodef@acm.org>
* type-hierarchy.ps: Added. This is a postscript file displaying
the type (meta-) hierarchy, for reference.
2001-04-22 Frode Vatvedt Fjeld <frodef@acm.org>
* binary-types.lisp: Added macro WITH-BINARY-INPUT-FROM-LIST that
sets up a "stream" variable suitable for READ-BINARY that provides
8-bit bytes from a list of integers.
2001-04-12 Frode Vatvedt Fjeld <frodef@acm.org>
* RELEASE: 0.74
* binary-types.lisp: The previous fix for DEFINE-BINARY-STRUCT's
lambda list was wrong. Hopefully this actually fixes it.
2001-04-11 Frode Vatvedt Fjeld <frodef@acm.org>
* RELEASE: 0.73
* binary-types.lisp: Changed in DEFINE-BINARY-STRUCT a (format
"MAKE-~A" name) to (format "~A-~A" '#:make name), which should
allow for lower-case lisps to work.
* binary-types.lisp: Modified DEFINE-BINARY-STRUCT's macro
lambda-list slightly to accommodate a bug in clisp. (This
shouldn't affect other systems at all.)
2001-03-29 Frode Vatvedt Fjeld <frodef@acm.org>
* RELEASE: 0.72.
2001-03-28 Frode Vatvedt Fjeld <frodef@acm.org>
* binary-types.lisp: Added macro WITH-BINARY-OUTPUT-TO-LIST that,
given a stream variable S, evaluates its body such that calls to
WRITE-BINARY to stream S collects in a list the individual bytes
as integers. This list is returned by the macro form.
* binary-types.lisp: Added two dynamic variables that allows you
to override the low-level IO functions binary-types use to read
and write single octets: *BINARY-READ-BYTE* and
*BINARY-WRITE-BYTE*, respectively. They default to the standard CL
functions READ-BYTE and WRITE-BYTE, and you may rebind them to any
function with the same signature.
* binary-types.lisp: Fixed bug in the expansion of
DEFINE-BINARY-STRUCT that caused nested declarations not to
work. This bug even made example.lisp not work. Sigh.
2001-02-19 Frode Vatvedt Fjeld <frodef@acm.org>
* RELEASE: 0.71.
* README: Revamped the documentation somewhat. Fixed up some
inconsistencies etc.
2001-02-13 Frode Vatvedt Fjeld <frodef@acm.org>
* binary-types.lisp: Changed some more syntax (slightly) in order
to be more consistent with CL syntax. Specifically,
DEFINE-BITFIELD now requires parens around the storage-type (as
does DEFINE-ENUM).
* example.lisp: Changed to reflext new syntax.
2001-02-12 Frode Vatvedt Fjeld <frodef@acm.org>
* binary-types.lisp: Changed syntax of DEFINE-ENUM. The
storage-type must be put in braces, and you may optionally specify
the :byte.
* binary-types.lisp: Added function ENUM-VALUE.
2000-11-01 Frode Vatvedt Fjeld <frodef@acm.org>
* binary-types.lisp: Changed COMPOUND-SLOT-NAMES to not include
padding slots, unless explicity requested.
* binary-types.lisp: Added method WRITE-BINARY-COMPOUND that is
like WRITE-BINARY only it will automatically look up the correct
binary-type from the object, and it only works on compounds (that
is, binary-classes and binary-structs).
2000-10-31 Frode Vatvedt Fjeld <frodef@acm.org>
* binary-types.lisp: Added slot-option :on-write, that provides a
function that will be called (at binary-writing time) on the
slot's value to obtain the actual value that is written.
2000-10-26 Frode Vatvedt Fjeld <frodef@acm.org>
* RELEASE: 0.70.
* binary-types.lisp: Renamed DEF-BINCLASS to DEFINE-BINARY-CLASS,
and DEF-BINSTRUCT to DEFINE-BINARY-STRUCT, and DEF-* to DEFINE-*.
* binary-types.lisp: Added a variation of the :BT slot-option. It
is named :BTT, and will have the extra effect of adding a :TYPE
slot-option to the class or struct slot. Be careful when using
this in DEF-BINSTRUCT to provide an slot-initform that is of the
correct type!
* binary-types.lisp: Changed the way nested declarations are
expanded. Now, even nested declarations will (in the expansion)
become top-level forms, I believe. This means that the
type-specifiers (the place after :BT in e.g. DEF-BINCLASS) is no
longer really evaluated, rather it is parsed by the
macro-expander. This means you no longer have to quote the
type-names (See "example.lisp"). Bitfield types are represented
symbolically by lists, so they are all of the lisp-type
"list". Fixed-size-nt-strings are equivalent to lisp strings (they
should really be strings of a maximum size, but lisp can't easily
express that concept). Also note that padding binary types which
are named by integer objects don't translate to lisp types at
all. This is just fine, I think, since padding "slots" are not
supposed to hold any lisp data.
* binary-types.lisp: Added DEFTYPE declarations so that all
binary-types also become lisp-types. For example, if you declare
(def-unsigned raw-number 1), you implicitly declare a lisp
type-specifier RAW-NUMBER that is equivalent to (integer 0 255).
2000-10-25 Frode Vatvedt Fjeld <frodef@acm.org>
* RELEASE: 0.61
* binary-types.lisp: Fixed bug in READ-BINARY for signed integers.
* binary-types.lisp: Added a WRITE-BINARY for binary-type
fixed-size-nt-string. Hopefully, read/write symmetry is complete
now. At least it should be possible to write the elf-header from
example.lisp.
* binary-types.lisp: Added DEF-BINSTRUCT macro, which is (supposed
to be) to DEFSTRUCT what DEF-BINCLASS is to DEFCLASS. If nothing
else, structs prints and reads more easily than classes. See the
definition of E-IDENT in the updated example.lisp.
2000-10-24 Frode Vatvedt Fjeld <frodef@acm.org>
* binary-types.lisp: Added class-option for DEF-BINCLASS
:class-slot-align that allows you to adjust the offsets by
declaring the offset of one slot. Like this
(:class-slot-align slot-name offset)
* binary-types.lisp: Added a class-option for DEF-BINCLASS,
:class-slot-offset <integer>, that specifies an offset to add to
any slot-offset as returned by SLOT-OFFSET.
* README-bitfield: This is my response to a query about how
DEF-BITFIELD works, included here to provide some documentation.
2000-10-23 Frode Vatvedt Fjeld <frodef@acm.org>
* RELEASE: 0.50
* binary-types.lisp: Added a macro WITH-BINARY-FILE that is a thin
wrapper around WITH-OPEN-FILE that tries to force the stream to
have the correct element-type.
2000-10-22 Frode Vatvedt Fjeld <frodef@acm.org>
* binary-types.lisp: Changed syntax of DEF-BINCLASS again, so that
it now completely matches the DEFCLASS syntax, only you have one
extra slot-option, :BT, which declares the slot's
binary-type. This slot-option is evaluated, so you may still have
nested declarations. What is new is that you may have slots that
don't have a binary-type. Such slots are simply ignored by
READ-BINARY and WRITE-BINARY.
2000-10-21 Frode Vatvedt Fjeld <frodef@acm.org>
* binary-types.lisp: Added COMPOUND-SLOT-NAMES, to replace
COMPOUND-ALIST and COMPOUND-MERGE which are now deprecated (the
functions are still there, but their symbols are no longer
exported..).
* binary-types.lisp: Changed the two BITFIELD-COMPUTE-XX-VALUE
from generic to regular functions (no reason for these to be
generic functions).
2000-10-20 Frode Vatvedt Fjeld <frodef@acm.org>
* example.lisp: Changed the example ELF header declaration to work
with the slightly changed syntax. Basically, all slots' type-field
is evaluated, so type-names (symbols) must be quoted.
* binary-types.lisp: Renamed DEF-COMPOUND to DEF-BINCLASS, and
changed the syntax so it looks more like DEFCLASS.
* binary-types.lisp: Added the capability of binary-integers to be
declared a certain endianess. So an integer is either :BIG-ENDIAN
or :LITTLE-ENDIAN (regardless of *ENDIAN*), or it depends
dynamically on the value of *ENDIAN*. The DEF-INTEGER macros now
takes and optional endianess argument.
* binary-types.lisp: Changed the (previously very ugly)
implementation of the binary-types name-space. Now use the new
accessor FIND-BINARY-TYPE which is implemented with a simple
hash-table. This means that BINARY TYPES MUST NOW BE NAMED BY
SYMBOLS (binary-types no longer touches the symbol-value of
symbols).
* binary-types.lisp: Removed generic function BIT-SIZEOF, since we
only deal with octets anyway.
* binary-types.lisp: Changed *ENDIAN* to take keyword symbols
:BIG-ENDIAN or :LITTLE-ENDIAN (old BT-interned symbols still
work).
2000-08-25 Frode Vatvedt Fjeld <frodef@acm.org>
* binary-types.lisp: Fixed reading of signed integers.
2000-06-13 Frode Vatvedt Fjeld <frodef@acm.org>
* README: Added a little more documentation.
* example.lisp: Cleaned up some small things.
2000-03-30 Frode Vatvedt Fjeld <frodef@acm.org>
* binary-types.lisp: Added write support for bitfield.
* binary-types.lisp: Changed the bitfield type to use proper CL
"bytes" for subfields.
1999-12-08 Frode Vatvedt Fjeld <frodef@acm.org>
* test.lisp: Added this file for tests of the BINARY-TYPES
package. Not much in it so far.
* binary-types.lisp: Fixed READ-BINARY for signed integers so it
actually works.
* binary-types.lisp: Added WRITE-BINARY for integers, char8,
padding, and compound.
* ChangeLog: Started
