9 years agoMerge: Better varargs
Jean Privat [Fri, 17 Oct 2014 00:20:53 +0000 (20:20 -0400)]
Merge: Better varargs

since their introduction in Nit, varargs had a quick and dirty implementation.
They where implemented with a complex path in the low-level parts of engine instead being implemented at  the AST level as it should be: varargs is more a syntactic sugar than something else.

Thus this PR changes the implementation of varargs in the engines.
This rationalize the `varargize` methods and simplify the code for low-level part (and also solve some bugs)

Additionally, the reverse-vararg, already accepted by the parser but unused until now, is implemented.
The principle it to pass an array where a vararg is expected.
Because of static ambiguities, the array passed as-is must be annotated with an ellipsis (`...`).

~~~nit
fun foo (xs: Object...) do print x.join("-")
foo(1,2,3) # prints "1-2-3"
var a = [1,2,3]
foo(a...) # prints "1-2-3"
foo(a) # pass `[a]`, a new array with a single element `a`, to foo, thus prints "123"
foo(1...) # Static Type Error: expected Array[Object], got Int.
~~~

Still, I think that error messages should be improved (cf. #98) but this seems to need some additional work in the error infrastructure.

A remaining question is what is the best acceptable type passed.
In the proposed implementation, the reverse-vararg must be a compatible Array (so a Sequence or a List are not accepted) and is given as is to the real method, that is allowed to modify it.
Should we change the type on a vararg to be a Sequence, a SequenceRead, of even a simple Collection ?

Jean Privat [Wed, 15 Oct 2014 20:15:47 +0000 (16:15 -0400)]
Merge: transform loops

In order to activate more optimizations and simplify code generators and analysis, the `while` and `for` loops must be transformed into simpler forms (in fact in complex forms but with simpler elements)

However, to do such a transformation, the escaping mechanism (break/continue/goto) must be rewrote.
Previously, for each loop control structure (loop for, while), a single EscapeMark was generated and breaks and continues are associated to the same mark, even if they branch in distinct points (so each escapemark had 2 branching mechanisms)
Now, with the first commits, two escapemarks are generated for each loop control structure, and breaks and continues are associated to a different one. The advantage is that each mark only have a single branching mechanism and that once associated to their mark, there is no need to distinguish break and continue (both become simple gotos).

The transformations of loops can be then implemented.

The `while`

~~~
while cond do block
~~~

is transformed into

~~~
loop if cond then block else break
~~~

and `for`

~~~
for i in col do block
~~~

is transformed into

~~~
var it = col.iterator
loop
   if it.is_ok then
      var i = it.item
      do block
      # ^ `continue` in the block it attached to the `do`
      # this is why the transformation of escape-marks where needed in fact.
      # and break is associated to the main loop
      it.next
   else
      break
   end
end
it.finish
~~~

Note that these transformations are basically what is currently implemented in rta, niti and nitg. Except that, now with a single transformation point, those three workers does not need to do their own transformation and basically can just rely on the one done on the AST level.

Merge: new option --define

It is standard in compiled programs to be able to setup some program configuration at compile-time.

Eg. C compilers accept a command-line option `-D` to define macros that will be used inside programs.
It is useful for configuring some string (like `-D PREFIX=/opt/nit/`, or `-D PORT=8081`) or activate some parts (conditional compilation, eg `-D WITH_SSL`).

This PR brings an equivalent capability to Nit engines through the new `-D` (`--define`) option.

The design behind the -D it to enable specific refinement of top-level functions at link-time.
Thus, basically

~~~sh
$ cat my_foo.nit
import foo
redef fun prefix do return "/opt/nit/"
$ nitg my_foo.nit
~~~

can be simplified into

~~~sh
$ nitg foo.nit -D prefix=/opt/nit/
~~~

Like `-m`, the `-D` creates a fictive module that refines the main module of the program.

`-D` also use the return type of the refined method to know how to interpret the text of the value.
Currently only Int, String and Bool is supported.

~~~nit
module foo
fun str: String do return "test"
fun num: Int do return 1
fun flag: Bool do return false
print str
print num
print flag
~~~

~~~sh
$ nitg foo.nit
$ ./foo
test
1
false
$ nitg foo.nit -D str=hello -D num=42 -D flag
$ ./foo
hello
42
true
~~~

The code of the PR is quite straightforward and show again that the new model is quite robust.

As usual, the first commits are some cleanup. The fun stuff is in the latter commits.

Jean Privat [Fri, 10 Oct 2014 13:08:30 +0000 (09:08 -0400)]
Merge: introduce `Iterator::finish`

While initially playing with for_abuse, an idea was to have the lib informed of an "end of iteration".

When the end of iteration was a result of `is_ok` false, it is easy for the lib to be informed.
But, if for some reason the client chose to abort the loop (with a `break` statement), the lib cannot be informed and some early release of resources cannot occurs.

This PR introduce a new optional service in iterators, namely `finish` that is automatically called at the end of `for` structures.

Currently, there is no user of such a function, but it is a POC that can be used for a nit-version of a `with` structure to implements for_abuse-like controls.

~~~nit
# Simple implementation of the `head` command
var head_limit = 10
for line in read_lines("some file") do
  # `read_lines` opens and reads each line
  head_limit -= 1
  if head_limit < 0 then break
  print line
end
# Here the file is automatically closed thanks to finish

9 years agoMerge: Improve Comparator type-kindness
Jean Privat [Mon, 6 Oct 2014 14:10:59 +0000 (10:10 -0400)]
Merge: Improve Comparator type-kindness

The Comparator class in Nit was a PITA because, with the traditional modelization with a generic class, Comparator is contravariant but Nit only allows covariance in its genericity.

Example:

~~~nit
var ao = new Array[Object].with_items(2,1,10)
ao.sort_with(alpha_comparator)
print ao.join(" ") # => 1 10 2

var ai = new Array[Int].with_items(2,1,10)
ai.sort_with(alpha_comparator)
# Static error: expected a Comparator[Int], got a Comparator[Object]
~~~

This PR implements the nice proposition of Etienne Gagnon to makes Comparator a non-generic class but use virtual types to control the type of compared elements.

It is clearly an improvement over the previous implementation:

* more expressive (++++)
* less code (+)
* simpler for the client (less generic stuff) (+)
* coherent with the `Comparable` hierarchy that also use virtual types (+)
* a little more complex for the lib (virtual type redefinition) (-)
* loss of information when things are typed with the interface `Comparator`, yielding to more potential covariance error at runtime (--)

While less type-safe than a full (and complex) contravariance solution, the proposed solution is still better in term of type-safety than dynamic languages and non-generic-non-virtual-type solutions (eg. Java4):

* runtime errors are detected earlier than with erasure or with dynamic typing (fail fast)
* some errors are still detected statically:

~~~
var a = [1,10,2,3]
alpha_comparator.sort(a)
print a.join(" ") #=> 1 10 2 3
default_comparator.sort(a)
print a.join(" ") #=> 1 2 3 10

var b = [true, false]
alpha_comparator.sort(b)
print b.join(" ") # => false true
default_comparator.sort(b)
# Static type error: expected Array[Comparable], got Array[Bool]
