Subject: [ jEdit-announce ] jEdit 4.2pre3 now available

jEdit 4.2pre3 is now available from <http://www.jedit.org>. This is a
bug fix release. It should be much more usable than 4.2pre1 or 4.2pre2.

Thanks to Brad Mace, Brant Langer Gurganus, Christoph Daniel Schulze,
Jonathan Revusky, Ken Turner, Kris Kopicki and Ollie Rutherfurd for
contributing to this release.

{{{ Editing

- The kill ring no longer shows duplicate entries, or entries that
  consist entirely of whitespace.

- Added emacs-like "deep indent" which can be enabled using the
  deepIndent buffer-local property:

  fooBar(baz,
         moreParameters,
	 ...); (Brad Mace)

- Just like the Find Previous command, S+ENTER in the search bar now
  shows an error message if regular expression search is enabled.
  Previously it would just search forward.

- The "Format Paragraph" command now shows an error message instead of
  just beeping if the wrap margin is not set.

- The "Paste Previous" and "Paste From List" dialog boxes now show the
  selected item in a multiple-line text area (Ollie Rutherfurd).

}}}
{{{ Syntax Highlighting

- Added LOTOS syntax highlighting (Ken Turner).

- Added SDL/PL syntax highlighting (Ken Turner).

- Added IMPORT element to RULES tag. All rules from the ruleset named
  by the required attribute DELEGATE are copied into this ruleset.

- Improved Velocity syntax highlighting.

- Added TPL syntax highlighting (Brant Langer Gurganus).

- Added UnrealScript syntax highlighting (Christoph Daniel Schulze).

- Updated FreeMaker syntax highlighting (Jonathan Revusky).

- Updated Pyrex syntax highlighting (Ollie Rutherfurd).

}}}
{{{ User Interface

- Activity Log now autoscrolls when dragging the mouse outside the log
  area bounds.

- Docked window menu buttons should now look better on MacOS X.

- When closing a buffer, the previous buffer is now selected, not the
  first buffer. The code that does this was actually there all along,
  but it never worked and I didn't notice (it would just go to the first
  buffer).

- On Windows, entering X:\ or X:/ where X is a drive letter will
  automatically list that drive so that further paths can be completed.
  This is similar to how on Unix entering / opens the root directory.

- Improved 'Choose Directory' dialog box.

- A warning dialog box is now shown if nothing is selected in the text
  area and the "search in selection" setting is activated.

}}}
{{{ Plugin Manager

- The plugin manager now lists JARs that do not contain a plugin core
  class.

- A warning is shown when updating a plugin from a version using the old
  API to a version using the new API, advising the user to restart
  jEdit.

- The plugin manager no longer removes an existing plugin if downloading
  of an update failed.

}}}
{{{ Optimizations

- Fixed a performance regression from pre2. Opening large files with
  soft wrap off should now be as fast (or faster) than 4.1.

- Fixed delays when exiting editor if help viewer and/or plugin manager
  windows were open.

- jEdit.getBuffer() now uses a hashtable instead of a linear scan.

- Optimized away some redundant code in the display manager, which
  should result in improved performance.

- Search dialog should open a little bit faster. This fixes the issue
  where if you press C+f and type a search string really quickly,
  characters would be inserted in the text area.

- Undo queue is now stored in a linked list, rather than an array. As
  offensive as it might sound, the array was being shifted along one
  position for each (non-compound) edit! Especially if the undo limit
  was set to a large value this could cause slowdowns.

- The buffer no longer grabs a write lock when calculating a fold level
  or syntax tokens for a line. This should prevent the text area from
  stalling if the buffer is being saved in an I/O thread.

- Fixed a performance regression from pre2. If all line contexts were
  valid, a subsequent request for a line's syntax tokens would
  invalidate all contexts from that line onwards. This did not happen if
  for example all but one context was valid.

- Faster directory listing in the file system browser.

- Fixed slowdown if activity log was docked and the "tail" option was on
  in Java 1.3.

- Floating positions are now stored in a more efficient data structure
  allowing operations to be performed in logarithmic time. This improves
  performance with plugins that create a lot of positions, such as XML
  and anything using ErrorList.

}}}
{{{ Bug Fixes

- Fixed NullPointerException when loading plugins if opened buffers
  contained an invalid 'folding' property.

- Fixed NullPointerException when invoking Complete Word in an edit mode
  that did not define a keyword map.

- Selecting 'Close' from a cloned dockable's popup menu closed the wrong
  window.

- Plugin manager window did not have the same icon as all other jEdit
  windows.

- "What's new in jEdit 4.2" document was missing from the download due
  to a packaging error.

- "Highlight every n lines" color setting in Gutter option pane didn't
  work properly.

- Plugin manager hardcoded the table foreground color to black, this
  could make the table unreadable if the text area background was dark
  and "use jEdit text area colors in all text controls" was on.

- EOL_SPAN_REGEXP rules threw NullPointerExceptions.

- Plugins that failed to load were not marked as such, and showed up as
  "Loaded" in the plugin manager.

- Added a workaround for a MacOS X Java bug where renaming a file to
  contain a path to a non-existent directory would delete the file.

- It is now possible to rename a file to another name that only differs
  in case on Windows.

- If "Ignore Case" was on, searching for strings containing certain
  characters (such as Unicode 0x00df) did not work since
  String.toUpperCase() sometimes mangles the string in various ways.
  Processing the string with Character.toUpperCase() doesn't seem to do
  this.

- The "Abbreviations" option pane now correctly handles expansions with
  duplicate abbreviations.

- An undoable edit is no longer merged if there is a pending redo. This
  would cause the undo queue to become inconsistent.

- Changed input modifier mapping on MacOS X.

  C+ is the Command key as before
  A+ is now the Control key
  M+ is no longer bound!

  A+ used to be the Option key however this caused problems such as
  special characters on international keyboards triggering jEdit
  shortcuts; for example, Option+' inserts # on an Italian keyboard, and
  jEdit would pick this up as A+QUOTE which is bound to "Scroll Page
  Up".

- Fixed NullPointerException when clicking in text area in a soft
  wrapped line that was but off at the bottom.

- Fixed NullPointerException when scrolling to a line that was longer
  than the visible area.

- Added a workaround for a problem with the Toolkit class which is
  non-reentrant on the Solaris JDK. This could cause a segmentation
  fault on jEdit startup.

- Fixed a problem in the text offset to screen line conversion. It
  usually manifested itself in the form of the "disappearing selection"
  bug; if only part of the first line was visible due to scrolling and a
  selection began in the part that was not visible, painting the
  selection would throw an exception which would result in the selection
  extension being removed from the text area.

- Printing is no longer done in a background thread, and now blocks the
  UI, due to various thread-safety problems.

- Printing a range of pages would always print starting from the first
  page.

- jEdit didn't compile with Java 2 version 1.3.

- Invalid delegates in syntax mode files could throw exceptions.

- "Spaces to Tabs" was broken.

- Added a workaround for the print spacing problem on some Java
  versions. Note that this results in much larger spool files. Enable in
  Utilities->Global Options->Printing.

- Added a workaround for buggy/incomplete implementations of JDK 1.4
  printing API. Now you can force use of the JDK 1.3 API when running on
  1.4. Enable in Utilities->Global Options->Printing.

- Re-introduced jEdit 3.2.2-style Unix window geometry workarounds. If
  you saw problems like dialog boxes getting smaller each time they were
  opened, etc, let me know if this fixes them.

- Fixed hang if a mode contains regular expression rules that match a
  zero-width string.

- The jEditLauncher configuration is no longer updated if installing a
  new jEdit release over an old one with the jEditLauncher de-selected
  in the installer.

- When searching for text, jEdit tries a little harder to make sure the
  search occurrence is visible if the text area needs to be scrolled
  horizontally.

- When using TAB to move focus from the buffer switcher, or search bar,
  etc. it should eventually end up in the text area, instead of getting
  stuck.

- Simplified key event workaround code. Let me know if you encouter any
  problems (such as garbage being inserted in the text area when certain
  keys are pressed, etc.)

- File dialog's completion was case sensitive when the TAB key was
  pressed. This was inconsistent with all other completion behavior
  which was case insensitive.

- File names that ended with a colon (:) were being treated like URLs
  even if there was no VFS named by the string before the colon. This
  made it impossible to open files named "foo:".

- Docking areas can no longer be resized beyond visible bounds if the
  "alternate tool bar layout" setting is off.

- Fixed a problem where the status bar would throw errors about negative
  array offsets if a buffer change resulted in the text area being
  scrolled.

- Glob patterns of the form {!{a,b,c}} didn't work properly.

- Browser actions were incorrectly written in the resource cache, so for
  example the FTP plugin's menu in the file system browser did not work.

- The install directory setting of the plugin manager didn't work.

- Refactored key dispatching code should make alternative keyboard
  layouts work better on MacOS X.

- gnu.regexp has rather strange substitution behavior, which caused
  problems with some SPAN_REGEXP's.

- Dialog box for confirming plugin removal now lists the JAR files to be
  removed in a scrolling list, this fixes the problem of the dialog
  getting too large in some cases.

- Fix a minor UI layout problem with the style editor dialog box of the
  Syntax Highlighting option pane.

- Fixed exception when reloading a buffer if a marker was set beyond the
  location where the buffer ends on disk.

- Fixed problem with table columns in the file system browser resizing
  incorrectly when a node was collapsed.

- Redoing a remove did not clear the buffer's modified flag if
  necessary.

- Fixed status bar display for prefixes longer than three keys.

- Pressing TAB in the action bar on JDK 1.3 would cause it to lose
  focus.

- Glob patterns containing + caused exceptions to be thrown.

- "Select Line Range" now respects the multiple selection setting.

- When installing updates, dependencies are now correctly installed
  (Kris Kopicki).

}}}
{{{ API Changes

- TokenHandler.handleToken() method now takes a Segment instance as
  the first parameter.

- Direct construction of SearchDialog no longer possible due to internal
  changes. The SearchDialog.showSearchDialog() method that has been
  recommended since jEdit 4.0 still works.

- Buffer.setReadOnly() can be used to make a buffer read only even if
  the file is writable on disk.

- Added JEditTextArea.addTopComponent() method (Brad Mace).

- Case-sensitivity is now determined on a per-filesystem basis, instead
  of always being on when running on Windows or MacOS X. To have your
  VFS be case-insensitive, define the CASE_INSENSITIVE_CAP.

- Added generic structure matching API for presenting the user a
  consistent interface for bracket matching, XML tag matching, BEGIN/END
  matching, etc.

  Simply write an implementation of StructureMatcher and add it to the
  text area with JEditTextArea.addStructureMatcher().
