The distinction between the "aul" and "non-aul" parts of
the script engine are mostly historical accident, and the
current organization of the source code does not use
sub-subdirectories. I'd like to keep it that way.
This reverts commit 69ba06b8d0.
There have been some bugs and crashes related to unwanted deep comparison (e.g. in the maze scenario). Scripters very rarely need deep comparison, so it should not be the default for the most commonly used operator.
This also changes behaviour of GetIndexOf to do pointer comparison.
This change has Guenther's seal of approval.
As discussed in http://forum.openclonk.org/topic_show.pl?tid=2917, I
have merged all copyright notices into a single file and referenced that
merged file from each source file.
For the updated source files, the timeline has been split into three
parts:
1. Pre-RWD code (before 2001)
2. RWD code (2001 through 2009)
3. OpenClonk code (2009 and later)
All pre-RWD copyright notices have been left intact, as have RWD-era
copyright notices where the file did not have a RedWolf design copyright
notice but only individual author ones. All copyright notices of the
OpenClonk era have been replaced by a single notice ranging from the
first recorded year to the current year (2013). Mape code did not get a
OpenClonk Team copyright notice because it is somewhat separate from the
main OpenClonk codebase and has only been touched by Armin Burgmeier.
The new type C4TimeMilliseconds behaves for the most part like a uint32_t but is overflow-proof in comparisons.
In some places, a 0-value (or uint_max) of the variable storing the time had the special meaning "not set yet". This has been resolved by having it as a pointer to C4TimeMilliseconds with NULL meaning that it has not been set yet.
This makes functions independent of their "Code Owner"s, which removes the
necessity to maintain that connection and carefully reset functions when
their scripthost is cleared.
Because the interpreter throws for every function that is called with a
this parameter that has been removed, this() isn't a function anymore.
The function could stay around so that Call("this") or foo->this()
would still work, but I doubt any script ever did that.
These operators have a stricter definition of equality than the == and !=
operators. Those are already stricter than in some other languages, so the
new ones are probably not needed very often. But if the need does arise,
there's no workaround short of modifying the data structures and checking
whether they are still the same.
The rope will create a C4AulScript for the rope engine functions instead of
putting them into the global scope, and we might want to put C4Object-only
functions into a separate C4AulScript some day, too.
The parser now copies the contents of the proplists in the order of their
source scripts into the final proplist. This way, local variable contents
get properly included, and the list of functions has one user less.
Also move C4AulDefFunc and C4ScriptFnDef to the same header the template
helper classes are in. Like them, these classes are a mostly invisible
implementation detail of the engine script functions.
The C4AulScriptContext is now an implementation detail of C4AulExec.
Also consolidate the C4Object * Obj and C4PropList * Def members to just
C4PropList * Obj and convert that to C4Object * on demand.
This short-circuiting operator will evaluate to its first operand if the operand
is not nil, or to its second operand otherwise. Its intended use is to simplify
defaulting expressions that may evaluate to nil to a valid value.
This requires replacing C4AulScript::Def with C4AulScript::GetPropList() and
C4DefScriptHost::Def, and making C4GameScriptHost::GetPropList return the
scenario proplist prototype.
Definition calls won't be able to change the local variables, of course.
Other proplists will be able to use local variables once they can have
functions.
0 is neither object nor definition, so the ordinary typecheck suffices.
Also change the error message to use '->' instead of object or definition
call.
