Jean Privat [Tue, 14 Apr 2015 09:33:40 +0000 (16:33 +0700)]
Merge: Fix type adaptation when there is loops

Basically one of the oldest bug of Nit.

The point of adaptive typing is that the static types of variables follows the static types of the assigned values, type tests and comparison to null.
This is a great feature of the language but was buggy because loops where not taken in account (old TODO), until the present PR.

The basic idea is just to track if a type adaptation occurs, if yes replay the whole typing phase.
The immediate drawback is that now typing require 2 passes most of the time, and sometime more.

This PR was a roller-coaster of emotions to develop since a lot a surprise issues were discovered.

* bug in flow that give me hours of despair.
* duplication of error messages; because multiple passes.
* premature warning/error messages; because some error conditions on types are detected at the first pass but a second pass find it is fine in fact... but too late the error message was printed.
* almost work at the first time (modulo the previous issues)
* only two bugs found in the whole code, quite impressive, and one of them is not a real bug but an autocast issue.

The issue about error duplication and premature errors is only workadounded (or fixme) in most places.
But proper solutions will be required in future PR.

close #647 and close #86, then reopen it again, then reclose it.

Merge: Intern new

A small short PR that enables a `new`-factory to instantiate itself.

previously there was no way to do that. The following code will stack-overflow:

~~~nit
class A
   new do
      var res = new A
      res.do_thigns
      return res
   end
end
var a = new A # infinite recursion of `new A`
~~~

Note: this is a very bad example as what is done in the previous `new` should be done in an `init` instead since it is related to the initialization of the object. A `new` factory should be exclusively used for some factory-concern like returning a more specialized object or returning an already existing object.

With this PR, the primitive constructor is available and is called `intern`, as the annotation that indicates things that cannot be programmed in Nit but are provided by the execution engine.

So in the previous example, just use this primitive constructor instead of doing a recursive call:

~~~
      var res = new A.intern
~~~

This intern constructor just do the allocation and the initialization of attributes with default values.
`init` is not called.

Maybe it should not do the initialization of attributes neither but if I skip them, there is no way for the programmer to ask for them manually. whereas `init` in not automatically called but can be called manually.

note: this PR is a small step toward the conclusion of the constructor saga, more will come soon (I hope)

9 years agoMerge: Sys is top
Jean Privat [Fri, 10 Apr 2015 15:19:40 +0000 (22:19 +0700)]
Merge: Sys is top

And when I say *top* I mean *great*. But I also mean *top* in fact.

The idea is to move the top-level methods (those defined outside classes) from Object to Sys.
While this is a cosmetic move, it has a lot of benefits:

* top-level methods get a real meaningful receiver: the current system. It is meaningful both on the declaration side and the call side.
* no more need to distinguish the concept of top-level methods with their rules and semantic, so this simplify the language with one less thing (almost, see bellow)
* self is now usable in top-level methods, not that useful now because it is `sys`, a singleton, but this allow some kind of inheritance if you add super-classes to Sys.
* no more name conflicts between a standard class method and a top-level method
* no more useless slots in table of classes for crazy methods defined in Object and never redefined
* close #461 and close #1081 by making them irrelevant
* Let us see a bright future where the singleton Sys become a multiton and allow specific isolation of computation. Specific Sys will then be active objects (threads, computation node, actors, whatever) isolated with their own specific cloud of objects and efficient lock-less concurrency, dedicated memory model (realtime?), and why not transparent distribution

There is still two drawbacks

* what is the status of `sys` that represent the current `Sys`? I hard-coded it to stay a method in Object. One way to solve the probem is to make it a keyword (like `self`)
* when doing `foo(x)`, first this tries `self.foo(x)` then `sys.foo(x)` thus this is some additional rule of the language.

Merge: new `with` statement

Introduce the `with` statement that is analogous to the `with` of Python or the `uning` of C#.

~~~nit
with x = something do
   x.work
end
~~~

That is equivalent with

~~~nit
do
   var x = something
   x.start
   x.work
   x.finish
end
~~~

Note that an alternative syntax, without the local variable exists:

~~~nit
with something do
   work
end
~~~

that is used when we want some automatic control or whatever. Eg resource allocation or critical section.

~~~nit
do
   var tmp = something
   tmp.start
   work
   tmp.stop
end
~~~

Most real-world examples could be

~~~nit
with file = path.create do
   file.write("Bla")
end
~~~

and

~~~nit
with a_mutex do
   work
end
~~~

## Names

I reused the `finish` method from Iterator.
I introduced the antonym `start` for the other side.

Note that the `start` is important because it helps the object to know it has to prepare itself for a `finish`.

I did not introduce an interface, mainly because I have no idea for a name. C# names it `IDisposable` and the `finish` method is called `Dispose`. There is no `start` because C# designers are lunatic sometime.

In python there is no interface (obviously) and the method are called
`__enter__` and `__exit__` because Python likes identifiers that resemble words eaten by boas.
Note that the returned variable is not the original expression but the result of `__enter__`.
With the Python semantic, but the Nit syntax, the first example will be equivalent to

~~~nit
do
   var tmp = something
   var x = tmp.start
   x.work
   x.finish
end
~~~

I am not sure of the benefits of the additional complexity, but the the more I thing about it the more I think this could be useful, ex for the control case the `start` can return the handler to `finish`.

The issue is that proposed syntax: `with x = something` does not make sense (because `tmp=something` and `x=tmp.start`) thus should be replaced with something else; Python uses `with something as x:` that we can reuse but I do not want because it is ugly.

An other alternative I tough of was to reuse the `for` keyword. but It is convoluted.
The two previous real world examples will then be

~~~nit
for file = path.create do
   file.write("Bla")
end
~~~

and

~~~nit
for a_mutex do
   work
end
~~~
