[Sablevm-developer] Code indenter / Uncompilable classes

[Etienne M. G. <eti...@uq...>]

Hi.

Lately, I have imported the latest sources from the Classpath repository into
sablepath-classes, using scripts to extract java sources (and related resource
files) and relocate them in a sane directory structure.

One thing I would like to have is a code indenter, somethink akin "indent".
This would simplify code maintenance as we could run the indenter along the
"import" scripts so that diffs with the vendor CVS branch wouldn't be
artificially inflated by simple code re-indentation.  Also, it makes life
simpler for everybody to have a uniform indentation style.

Personally, I would like a program that indents programs closely to the "GNU C"
style, with matching parenthesis level, one space between identifier/keyword
and "(", with minor modifications... something like:

void foo (int a, long b)
  {
    ...
  }

*** NOT *** 

void
foo( int a , long b ) {
  ...
}

Anyone knows a *** robust *** program to do so?  All the ones I have tried so
far have bugs when confronted to inner-classes/anonymous classes, or are not
flexible using Sun's ugly unmatched "{" "}" levels, etc.

The latest Classpath source files are mostly broken under Jikes (I'm using
version 1.14).  So I have cheated, and tried compiling them under "javac".  [I
am not checking that semantics are OK, just that they compile].  Even this is
asking a lot from Classpath...  There are 20 classes that are definitely
broken.  Here is the list:

src/gnu/javax/swing/plaf/gtk/GtkBorders.java
src/gnu/javax/swing/plaf/gtk/GtkCheckBoxUI.java
src/gnu/javax/swing/plaf/gtk/GtkIconFactory.java
src/gnu/javax/swing/plaf/gtk/GtkLookAndFeel.java
src/gnu/javax/swing/plaf/gtk/GtkRadioButtonUI.java
src/gnu/javax/swing/plaf/gtk/GtkSliderUI.java
src/java/util/jar/JarEntry.java
src/java/util/jar/JarFile.java
src/java/util/jar/JarInputStream.java
src/java/util/jar/JarOutputStream.java
src/javax/accessibility/Accessible.java
src/javax/accessibility/AccessibleHypertext.java
src/javax/accessibility/AccessibleText.java
src/javax/swing/GrayFilter.java
src/javax/swing/plaf/BorderUIResource.java
src/java/net/JarURLConnection.java
src/javax/accessibility/AccessibleComponent.java
src/javax/accessibility/AccessibleSelection.java
src/java/net/URLClassLoader.java
src/java/util/IdentityHashMap.java

I have not looked for the reason why these are broken.  More annoying is the
fact that many classes, including "core" library classes (I think java.io.File
is part of them) are broken under Jikes.  Jikes seems to die with something
like a "signal 11".

As usual, you must be careful to set BOTH the "-bootclasspath" and "-classpath"
command line options to for the compiler to use "SablePath" as its core system
library when you compile the code (with jikes and/or javac).

All help/suggestions would be appreciated.

Have fun,

Etienne
