Eclipse 3.3 M1 新特性一览

Eclipse项目发布了3.3 M1. 新的发布版本进一步增强了eclipse在 SWT, debugging, platform text, JDT UI, installation wizards, 等方面的功能.

SWT
Printing support added on GTK+	Printing support has been added to SWT for GTK+. It is important to note that you must be running with GTK+ 2.10 or newer in order for this support to be utilized.
Option to print line numbers added to StyledText	When printing a StyledText widget, line numbers can now be printed by setting the StyledTextPrintOptions.printLineNumbers field to true.
System tray support added on Mac OS X	Icons placed on the system tray will now appear in the Mac OS X status bar.
Writing PNGs now supported	Images can now be written to disk in PNG format (example snippet).
Browser profiles now utilized on GTK+ and linux-motif	The Browser widget is now utilizing profiles on GTK+ and linux-motif. As a result many previous shortcomings have been fixed, including the inability to display https pages, not rendering visited links properly, and not caching visited pages.
Browser support added on PowerPC	Browser support has been added for the PowerPC architecture (GTK+).
GtkComboBox now utilized when available	GtkComboBox is now utilized natively for users that are running with GTK+ version 2.4 or newer.
User Assistance
Help home button	The help window now has a Home button in the navigation toolbar, which brings you back to the initial product-configurable home page.
Help search term highlighting	If you open a help document as a result of a search, a new toggle button will appear in the toolbar allowing you to toggle the search term highlighting on and off, making the document easier to read.
Debug
Browse all references (J2SE 6 only)	If you’re running your Java application with a J2SE 6 virtual machine, you can browse all references to an object in the variables view. Select any object in the variables view, and choose All References from the context menu. A pop-up displays all objects referring to the selected object. You can expand each node in the tree to follow references to each object. You can inspect any object in the reference tree by selecting it and pressing Ctrl+Shift+I. This opens an inspect pop-up displaying the object’s fields.
No more prompting	A user preference now controls whether you are prompted to confirm the deletion of all breakpoints in the workspace. The new preference is available on the Run/Debug preference page. As well, a check box in the confirmation dialog allows you to set the preference.
Auto format stack traces	Stack traces can be formatted automatically as you paste them into the Java stack trace console. An "Auto Format" toggle is available on the console tool bar.
Double-click and Ctrl+Shift+B for all kinds of breakpoints	Double-clicking in the vertical ruler, or invoking Toggle Breakpoint (Ctrl+Shift+B), now creates an appropriate kind of breakpoint based on the cursor location - line breakpoint, watchpoint, method breakpoint, or class load breakpoint. To create a class load breakpoint, double click on the class declaration line.
Platform Text
Scroll by pages using Ctrl + mouse wheel	The mouse wheel scrolls the content of a textual editor by pages while the Ctrl key is pressed.
More flexible templates	The syntax for templates has evolved to allow typed and parameterized template variables. This allows the same variable type to be used multiple times in the same template. As an example, consider the following template for generating a doubly nested for loop:
Contribute columns to vertical ruler	A new extension point, org.eclipse.ui.workbench.texteditor.rulerColumns allows the contribution of columns to the vertical ruler of any text editor.
JDT UI
Scripted refactorings	Now all refactorings offered by the Java Development Tools can be scripted, including Move, Copy, Paste, and Delete. Use Refactoring > Create Script to create a script from the refactoring history and Refactoring > Apply to apply one.
More Java search options	The Java search dialog has been extended to offer finer control to limit the scope to search in sources, JRE libraries, required projects, and application libraries.
Paste type declaration creates new project	Ever wanted to quickly try out a code snippet somebody sent to you? Copy the snippet to the clipboard, go to the Package Explorer, select nothing, and choose Edit > Paste (Ctrl+V). Eclipse will try to parse the contents of the clipboard, and if it looks like contents for a *.java file, it will create a new Java project and paste the *.java file. Like in 3.2, you can, of course, still select an existing project or package as target for the new file.
JDT Text
Template for adding JUnit 4 test methods	A new Test template has been added to speed up adding JUnit 4 test methods.
Configurable Javadoc font	The font for displaying Javadoc is now configurable on the General > Appearance > Colors and Fonts preference page. The Javadoc display font is used by the Javadoc view and hover, and for the additional information shown during content assist.
Syntax coloring for brackets	Brackets may now be colored separately from operators in the Java editor via the Java > Editor > Syntax Coloring preference page.
Update/Install
Install wizard improvements	The Installation page of the Install wizard now presents features in an easy-to-use table that includes the name, version, size, and target location of each feature. A Change Location button lets you easily change the target location of the selected features.
Team/CVS
Import CVS projects directly into working sets	You can now assign CVS projects to a working set during the import step. This is available from both the CVS Repository View (via Check Out As) and through the CVS Import Wizard.
Export working sets as part of team project set	The export wizard is now able to persist active working sets as part of a Team Project set.
History view search	The History View has a new search field which allows you to perform a quick search on the displayed revisions. The search compares the author, comment, revision, and tags against the entered string. The field is accessible via the drop down menu.

PDE
Content assist in plugin.xml	Content assist (Ctrl+Space) is now available on the plugin.xml source page to give you context-sensitive information as you create extensions and extension points. Features include: completion proposals for extensions, extension points, attributes, and elements auto-generation of required elements and attributes Note that the content assist can be activated without the need for a partial string. PDE uses extension point schemas to determine which elements and attributes are suitable for the current context.
Content assist in MANIFEST.MF	Content assist (Ctrl+Space) is now available on the MANIFEST.MF source page, including completion proposals for: header names, attributes, and directives header values such as plug-in IDs, package names, and Java class names boo lean and enumerated values for attributes and directives
Field assist in Forms	All fields denoting classes in the plug-in manifest editor now support a field assist feature to help you complete the name of a partially entered class name. This feature works in a similar way to the content assist in the Java editor, and supports package names and CamelCase.
Hyperlinking and open declarations	Hyperlinking (i.e. the use of Ctrl+Left to navigate from one editor to another) is now supported on the plug-in manifest editor source page. The usage of the F3 key to open declarations is also supported and provides the same functionality as hyperlinking. Hovering over attribute values on the plugin.xml page and pressing Ctrl+Left can be used to open resources and Java type declarations open extension point schema descriptions navigate from a translated key reference to that key in the properties file Hyperlinking provides additional functionality on the MANIFEST.MF source page including: opening manifest editors for referenced plug-ins opening referenced packages
Code folding	Folding is now supported on the plugin.xml and MANIFEST.MF source pages of the plug-in manifest editor to make large files more manageable. The option to turn folding on and off can be found on the Plug-in Development > Editors preference page.
Code formatting	Line wrapping introduced by some packaging tools make the plug-in MANIFEST.MF file hard to read. PDE now provides a Format action in the context menu of the MANIFEST.MF source page to format the contents of the file into something more human-readable.
Filtered extensions	The Extensions tab of the plug-in manifest editor allows the filtering of the Extensions tree based on a text filter. This function is particularly useful when searching for that one contribution among a long list of extensions.
