| 6bf19a | 2002-09-15 | Peter Bortas | | Changes since Pike 7.2:
----------------------------------------------------------------------
|
| cd683a | 2001-07-27 | Johan Sundström | |
|
| bf7e8e | 2002-09-26 | Martin Nilsson | | New/improved functionality:
---------------------------
|
| cd683a | 2001-07-27 | Johan Sundström | |
|
| 6bf19a | 2002-09-15 | Peter Bortas | | o New Hilfe
|
| d4ce82 | 2002-09-26 | Johan Sundström | | The interactive pike environment you get when running pike without
giving a program name, has been thoroughly rewritten. Most notably
it now supports more of the common pike constructs, and is more
extendable and configurable. Start it and type help for more info.
|
| cd683a | 2001-07-27 | Johan Sundström | |
|
| 7ab100 | 2002-10-31 | Martin Nilsson | | o AutoDoc
|
| 6bf19a | 2002-09-15 | Peter Bortas | | o pike -x
|
| d4ce82 | 2002-09-26 | Johan Sundström | | When starting pike with the -x parameter, the pike process will
run the named script in Tools.Standalone, giving the rest of the
arguments as command-line switches. This is a convenient way of
running rsif (replace string in file) and pv (the image viewer
you may be familiar with from Tools.PV).
|
| cd683a | 2001-07-27 | Johan Sundström | |
|
| 6bf19a | 2002-09-15 | Peter Bortas | | o unbug
|
| d72917 | 2002-07-14 | Honza Petrous | |
|
| bf7e8e | 2002-09-26 | Martin Nilsson | | o Unicode 3.2.0
|
| 99b2a6 | 2002-09-26 | Henrik Grubbström (Grubba) | | All charts have been updated to Unicode 3.2.0. This applies both to
the Unicode module as well as to Pike-global functionality such as
|
| bf7e8e | 2002-09-26 | Martin Nilsson | | upper_case/lower_case. unicode_to_string() also has support for
surrogate and byteorder make handling.
|
| d72917 | 2002-07-14 | Honza Petrous | |
|
| bf7e8e | 2002-09-26 | Martin Nilsson | | o Extended random()
|
| bd8a48 | 2002-10-27 | Martin Nilsson | | random() now works on floats, arrays, multisets, mappings and
objects in addition to integers.
|
| bf7e8e | 2002-09-26 | Martin Nilsson | |
o delay()/sleep()
|
| bd8a48 | 2002-10-27 | Martin Nilsson | | sleep() no longer busywaits, which it previously did for small
values. The old behaviour is available from the delay() function.
|
| bf7e8e | 2002-09-26 | Martin Nilsson | |
|
| d4ce82 | 2002-09-26 | Johan Sundström | | o search(string, int) / has_value(string, int)
Both of these methods now handle both looking for strings and
|
| 378751 | 2002-09-27 | Johan Sundström | | integers (the unicode number for a single character).
Examples: search("hi, ho!", '!'), has_value("Nope.", ' ')
|
| bf7e8e | 2002-09-26 | Martin Nilsson | |
Language additions:
-------------------
|
| 6bf19a | 2002-09-15 | Peter Bortas | |
|
| 638b8d | 2002-09-22 | Martin Stjernholm | | o foreach(X; Y; Z)
The foreach statement has been extended to allow iterations over
mappings, multisets and any object that implements the iterator
interface (see below). To make it possible to use this
conveniently, a new syntax has been added to get both the index
and the value in each iteration:
foreach (something; index-expr; value-expr) ...
This iterates over something, assigning in turn each index to
index-expr and each value to value-expr. The index and value
expressions can be declarations or lvalues, and they can also be
left out if the index and/or value part isn't interesting.
Note that it depends on the data type whether the iteration order
is well defined or not; arrays and multisets are iterated over
starting with the first element while mappings are visited in some
arbitrary order (each element is still visited only once, though).
o Iterators
As noted above, an iterator interface has been added that is now
used in various places to iterate over different data structures.
Not only the built-in data types are supported, but actually any
object that fulfills the interface for iterators:
When iterating over an object o, o->_get_iterator() is called to
|
| 99b2a6 | 2002-09-26 | Henrik Grubbström (Grubba) | | get an iterator object. An iterator object should at least have
two functions, index() and value(), to get the index and value
at the current position, a function `+=(int steps) to advance the
current position the specified number of steps, and a `!() that
returns zero if the position hasn't reached the end of the data set.
|
| 638b8d | 2002-09-22 | Martin Stjernholm | |
Also, if the object o lacks a _get_iterator function, it's assumed
to be an iterator itself. This makes it possible to pass an
iterator explicitly to e.g. the foreach statement.
The built-in data types also have iterator classes with this
interface. They are found as Array.Iterator, Mapping.Iterator, etc
and can be used to iterate over these data types in some custom
fashion. This is especially useful for mappings and multisets,
which cannot be iterated over directly in any other way. For
example, to get some arbitrary index in a mapping m:
mixed any_index = Mapping.Iterator(m)->index();
|
| 6bf19a | 2002-09-15 | Peter Bortas | | o Automap
|
| 4ec62a | 2002-10-31 | Johan Sundström | | To perform per-element operations on arrays, there is now a convenience
syntax for map(), that can make code more readable in some situations.
Summing up two arrays element by element using automap looks like this:
a[*] + b[*]; // the result has as many elements as the shortest array
Multiplying all elements in a by a constant:
a[*] * 4711;
Make an array of what sprintf("%O", a[n]) returns for all elements in a:
sprintf("%O", a[*]);
|
| 6bf19a | 2002-09-15 | Peter Bortas | |
o Implicit lambda.
|
| 638b8d | 2002-09-22 | Martin Stjernholm | | o Access to hidden variables in surrounding scopes.
Include the names of the surrounding classes themselves in the lookup for
Foo::, to make it possible to adress hidden variables in the scopes of
surrounding classes, e.g:
|
| 6bf19a | 2002-09-15 | Peter Bortas | |
|
| 638b8d | 2002-09-22 | Martin Stjernholm | | class Foo {
int i;
void create (int i) {Foo::i = i;}
}
|
| 6bf19a | 2002-09-15 | Peter Bortas | |
|
| 638b8d | 2002-09-22 | Martin Stjernholm | | o global::
Added new keyword global to be able to access identifiers on the
top level of the compilation unit using global::foo.
|
| 3dbeca | 2002-09-16 | Johan Sundström | |
o global.
All top level modules (and other identifiers in that scope) can now
|
| 638b8d | 2002-09-22 | Martin Stjernholm | | be accessed with a "global." prefix. This is useful in cases where
|
| 3dbeca | 2002-09-16 | Johan Sundström | | local identifiers overshadow the top level, for instance in the Image
module, where the Image.Image class would occasionally block your view.
|
| 6bf19a | 2002-09-15 | Peter Bortas | |
o this
Added a magic identifier "this" that can be used instead of
this_object(). Like this_program, it only exists when there's no
|
| 638b8d | 2002-09-22 | Martin Stjernholm | | other identifier with that name. The primary reason for adding
this magic identifier is to make it possible to address the object
of a surrounding class with Foo::this.
|
| 6bf19a | 2002-09-15 | Peter Bortas | |
|
| 638b8d | 2002-09-22 | Martin Stjernholm | | o The Local module
|
| 2ee5a4 | 2002-10-31 | Johan Sundström | | All Pike modules and classes found in the directory hierarchies
/usr/local/pike_modules, /opt/pike_modules, /opt/share/pike_modules,
/usr/local/share/pike_modules, $HOME/pike_modules, and
$PIKE_LOCAL_PATH (a :-separated list of directories) are available
with the prefix "Local.". Local.add_path() and Local.remove_path()
respectively adds and removes entries from the list of paths to
inspect when resolving Local.* symbols.
|
| 6bf19a | 2002-09-15 | Peter Bortas | |
o enum reserved
o enum and typedef have implicit local binding
|
| 638b8d | 2002-09-22 | Martin Stjernholm | | o ::_indices(), ::_values().
There are now two "magic" functions ::_indices() and ::_values()
that can be used by an object to list all identifiers and their
values in itself. They are primarily intended when the _indices()
and _values() lfuns have been defined, to get the default
implementations. This is to complement the "magic" ::`->() and
::`->=() functions that exist in earlier releases.
|
| 6bf19a | 2002-09-15 | Peter Bortas | |
|
| bf7e8e | 2002-09-26 | Martin Nilsson | | o UNDEFINED
|
| 57f295 | 2002-10-31 | Johan Sundström | | To generate a 0 (zero) with a zero_type(var) == 1, you previously
had to use constructs like ([])[0]. This is now available as the
globally available symbol UNDEFINED.
|
| 6bf19a | 2002-09-15 | Peter Bortas | |
|
| bf7e8e | 2002-09-26 | Martin Nilsson | | o _m_delete
|
| ef621d | 2002-10-31 | Johan Sundström | | There is now an LFUN mixed _m_delete(mixed index) to overload in
your classes to imitate mappings. It gets invoked when m_delete
is performed on your object.
|
| 6bf19a | 2002-09-15 | Peter Bortas | |
|
| bd8a48 | 2002-10-27 | Martin Nilsson | | o :: includes current class
class X {
int i;
void create (int i) {X::i = i;}
}
|
| cd683a | 2001-07-27 | Johan Sundström | |

Compatibility changes:
----------------------
|
| 638b8d | 2002-09-22 | Martin Stjernholm | | The following changes are known to break compatibility. The old
behaviour is emulated in the compatibility layer that is activated by
adding the preprocessor directive "#pike 7.2" to your program or by
giving the argument "-V7.2" to the pike executable.
o "global" has become a reserved keyword.
o Changed lookup rule for ::.
Previously the identifier in front of :: was only looked up among
the preceding inherits. Now the lookup additionally includes the
names of the surrounding classes. The inherits inside a class
still take precedence over the name of the class, though.
o Using local:: on variables is an error.
Previously the construct local::foo could be used to access the
identifier "foo" in the class scope if it had been overridden by
an argument or function variable. That is however only a
side-effect of the real use for local::, namely to bind the
identifier statically at that point only, to avoid getting an
overridden version. In the case of variables this leads to
questionable semantics, which is the reason it's been made an
error in this version. Pike 7.2 didn't implement it correctly;
there local:: on variables had only the effect to access the class
scope. Now a proper way to access hidden identifiers has been
added, so all such uses of local:: should be replaced with
this_program::.
|
| 6bf19a | 2002-09-15 | Peter Bortas | |
|
| 1d89c5 | 2002-09-24 | Johan Sundström | | o Identifier lookup
The search algorithm for finding identifiers from inherited classes
has been changed to look for the most recent definition in the most
recent inherit. In Pike 7.2 and prior, it looked up the last
definition regardless of inherit depth, unless there was a
definition in the current program. (This actually changed more than
once during 7.3 - between 7.3.23 and 7.3.32, it looked up the most
recent definition with the least inherit depth.) This example shows
what the lookup strategies would find:
class A {
int foo() {}
}
class B {
int foo() {}
inherit A;
}
class C {
inherit B;
}
class D {
inherit B;
inherit C;
}
Lookup of identifier "foo" in D():
D-+-B-+-foo Pike 7.3.23 --- Pike 7.3.32
| |
| +-A---foo
|
+-C---B-+-foo Pike 7.3.33 --- (present day)
|
+-A---foo --- Pike 7.3.22
Lookup of identifier "foo" in C():
C---B-+-foo Pike 7.3.23 --- (present day)
|
+-A---foo --- Pike 7.3.22
Lookup of identifier "foo" in B():
B-+-foo All versions of Pike
|
+-A---foo
|
| 7ab100 | 2002-10-31 | Martin Nilsson | | o Image.Layer modes modified
Alpha channel handling for modes add, subtract, multiply, divide,
modulo, invsubtract, invdivide, invmodulo, difference, max, min,
bitwise_and, bitwise_or, bitwise_xor, screen and overlay modified so
that the source layer alpha channel copied to the destination layer
alpha channel rather then mixed with the current layer alpha channel:
aD=aS
rather then the behavior before:
aD=(aL+(1-aL)*aS)
(which is the behavior of the 'normal' mode.)
Bug fixes in the above modes so that alpha r,g,b channels
|
| 03360f | 2002-10-31 | Johan Sundström | | are handled properly (separately).
|
| 7ab100 | 2002-10-31 | Martin Nilsson | | Bug fixes in equal, not_equal, less, more, less_or_equal,
more_or_equal modes so that the alpha channel is handled as
documented (which is, in fact, as above; aD=aS).
|
| 03360f | 2002-10-31 | Johan Sundström | |
|
| 7ab100 | 2002-10-31 | Martin Nilsson | | Bug fix in divide, invdivide to actually do what the modes
are supposed to do (rather then just black the layer).
|
| 03360f | 2002-10-31 | Johan Sundström | |
|
| 7ab100 | 2002-10-31 | Martin Nilsson | | And while on it, adding some modes:
|
| 03360f | 2002-10-31 | Johan Sundström | |
|
| 7ab100 | 2002-10-31 | Martin Nilsson | | 'imultiply' - D=(1-L)*S
'idivide' - D=S/(1-L)
'invidivide' - D=L/(1-S)
|
| 03360f | 2002-10-31 | Johan Sundström | |
|
| 7ab100 | 2002-10-31 | Martin Nilsson | | 'value_mul' - multiplying the source layer value
|
| 03360f | 2002-10-31 | Johan Sundström | | (as in h,s,v) with the current layer value to the destination
layer ("true burn").
|
| 7ab100 | 2002-10-31 | Martin Nilsson | |
NOTE: There is no backward compatibility functions added for use
with #pike.
o Thread.Condition()->wait
|
| 46e6d8 | 2002-10-31 | Johan Sundström | | o Protocols.HTTP
All methods in Protocols.HTTP that take a header mapping can now
handle array values (signifying multiple headers of that type).
|
| 6bf19a | 2002-09-15 | Peter Bortas | | o Protocols.LDAP.client
The return code from all methods was changed to follow Pike's
logic better. 0 is now a failure. The old behaviour is emulated in
|
| 99b2a6 | 2002-09-26 | Henrik Grubbström (Grubba) | | a compatibility layer.
|
| 6bf19a | 2002-09-15 | Peter Bortas | |
o dirname
Now correctly returns a directory instead of just stripping the
|
| 99b2a6 | 2002-09-26 | Henrik Grubbström (Grubba) | | part after the nearest directory separator.
|
| 6bf19a | 2002-09-15 | Peter Bortas | |
o LR
LR has been moved to Parser.LR and the API has been chnged.
FIXME: More about this?
|
| bf7e8e | 2002-09-26 | Martin Nilsson | | o wmml documentation removed
Use the documentation in the refdoc directory instead.
o .build_lobotomize_crypto removed
Use the Makefile target lobotomize_crypto to lobotomize Pike.
|
| 99b2a6 | 2002-09-26 | Henrik Grubbström (Grubba) | | Should preferably be executed in an unused tree straight from CVS.
|
| bf7e8e | 2002-09-26 | Martin Nilsson | |
C level/development changes:
----------------------------
|
| 99b2a6 | 2002-09-26 | Henrik Grubbström (Grubba) | | o Some global symbols have been renamed to avoid name clashes.
|
| bf7e8e | 2002-09-26 | Martin Nilsson | | sp -> Pike_sp
fp -> Pike_fp
fatal -> Pike_fatal
empty_string -> empty_pike_string
o --with-internal-profiling
o Module symbols not available from other modules.
|
