Reversed the values of "is" and "is not" in recent for comprehension
deprecation.
DO NOT BLOW HATCH
REPEAT
DO NOT BLOW HATCH
"Roger! Hatch blown."
Events reveal it was all baby, no bathwater. It turns out that the
specification is merely a document, not infallible holy writ as we
had all previously believed. So it is not the ABSENCE of val in a for
comprehension assignment which is deprecated, it is the PRESENCE of val.
Summarizing again, more accurately perhaps:
for (x <- 1 to 5 ; y = x) yield x+y // THAT's the one
for (val x <- 1 to 5 ; y = x) yield x+y // fail
for (val x <- 1 to 5 ; val y = x) yield x+y // fail
for (x <- 1 to 5 ; val y = x) yield x+y // deprecated
No review.

[MSIL] finer-grain debugging (steps one sub-expression at time).

(1) The msil library can now parse modreq and modopt, (2) bug fix in
GenMSIL. review by rytz. Updated msil.jar coming soon.

Who knew system was such a popular sentence ending choice. Fixes some

Imported sbt.Process into trunk, in the guise of package
scala.sys.process. It is largely indistinguishable from the version in
sbt, at least from the outside.
Also, I renamed package system to sys. I wanted to do that from the
beginning and the desire has only grown since then. Sometimes a short
identifier is just critical to usability: with a function like error("")
called from hundreds of places, the difference between system.error and
sys.error is too big. sys.error and sys.exit have good vibes (at least
as good as the vibes can be for functions which error and exit.)
Note: this is just the first cut. I need to check this in to finish
fixing partest. I will be going over it with a comb and writing
documentation which will leave you enchanted, as well as removing other
bits which are now redundant or inferior. No review.

(1) the Scala types in ch.epfl.lamp.compiler.msil.emit now use Scala
collections instead of Java's, (2) a few bug fixes regarding metadata
parsing, (3) GenMSIL emits output useful for IDE debugging, (4)
TypeParser now enters symbols for generics in case the assemblies being
linked sport them, (5) a few fixes for bytecode verif in GenMSIL.

(a) The bytecode that Scala.NET emitted had a tough time in
passing peverify due to valuetypes (aka structs) and their related
managed-pointer types. With these changes (details in [1] and [2])
external APIs exposing valuetypes can be used, yet the extra step of
supporting defining valuetypes in Scala programs has been left for
later. Supporting the unsigned integral valuetypes (used, among others,
by IKVM) is also pending.
(b) A very first step towards generics can be found in
TypeParser.parseClass, for the time being commented out (search for
the label "TODO CLR generics"). It's commented out because without
CLRManifests codegen won't work as expected. Details in [3].

for MSIL: Previous changesets were applied more-or-less incrementally to
scala-msil, this changeset brings them all together to scala trunk. Next
stop will be supporting CLR valuetypes (another big one). Afterwards
(once emitted .NET bytecode passes peverify) changesets will become more
manageable in size. Well, no, there's generics coming. But believe me,
soon MSIL changesets will get smaller in size.

Reverted my brainless introduction of ## to a java file. Closes #3716,
no review.

Altered a bunch of places which call hashCode to call ## instead. No
review.

As a brief diversion from real work, implemented Damerau–Levenshtein
and ran it on trunk to elicit obvious misspellings. Unfortunately
they're mostly in places like compiler comments which real people never
see, but I fixed them anyway. All those English Lit majors who peruse
our sources are sure to be pleased. No review.

object, updating some @deprecated messages to give realistic
alternatives, properly resolving the semantic mismatch between List.--
and diff, its once-recommended but inequivalent alternative.

Finally completed the incredibly tedious task of removing the lower case
primitive aliases from Predef. Had to rebuild msil.jar along the way.
|
| |
|
|
|
|
|
| |
The preferred way to convert between primitives is to call .toInt etc,
but there were lots of casts for historical reasons. This patch remedies
that.

[no content change] Fixed all SVN properties: mimes, EOL, executable. Id
expansion is consistently enabled for Scala/Java/C# sources in 'src/'
and consistently disabled and removed from everywhere else: there should
not be any dead Id tags anymore.

In "Iterable" and in all its subclasses, "iterator" replaces "elements"
(and assorted changes).
