The R Project SVN R-packages

NEWS

-- Release Version 1.01 - this revision is supplied with R 2.0.1 --

Last update: 2004-11-16 [SU]
*   fixed handling of line endings: PC endings (\r\n) are now supported
    as R console input (also fixes some problems with AppleScript)
*   added transport buffer for ReadConsole to be logically correct.
    this also remedies the compilation warning in RController
*   fixed a bug in isAdmin() - uninitialized variable

Last update: 2004-11-14 [SU]
*   added isAdmin() in Tools/Authorization to query the admin status
    of the current user (more precisely membership in the "admin" group)
*   changed default package installation target - for admin users the
    default is now system-wide installation
*   clean-up of the MiscPrefPane, removed redundant code from RController
*   added support for R_LIBS option: in MiscPrefs there is a flag that
    can be set resulting in ~/R/Library to be added to R_LIBS. This
    obsoletes hack in Rprofile which modified .libPaths without respecting
    or updating R_LIBS which in turn broke some R CMD ... scripts.
    Note that this setting has no effect if the hack is still in place
    (most notably in the R 2.0.0 release)
*   added R_GUI_VERSION_STR define
*   R_GUI_APP_VERSION environment variable is set by R.app such that R
    code can check the existence and version of the R.app

Last update: 2004-11-06 [SI]
*   added Rob Goedman (for external editor support) code.
*   added standard copyright notes everywhere. Please check and
    add specific credits to users contributed code if any.
    
Last update: 2004-11-05 [SU]
*   fixed a small leak and early deallocation of the keywordList (this fixes
    crash observed when editing a file dropped on R while R is initialized).
    retain all colors, too, to make sure they don't get deallocated
*   added SortedDataSource which provides a persistent table as data source.
    it is used by DataManager now and should by used by all managers later.
    the sorting part is not implemented yet, though.

Last update: 2004-10-30 [SU]
*   moved callbacks for data manager, package manager, package installer
    and system command out to a separate handler. This means rather major
    changes in the code and the way data is stored in those managers (removed
    all global variables for the above managers). There are now two handlers in
    REngine - one mandatory (REPL) and one optional (Cocoa).
*   separated authorization code - it lives now in Authorization.c in Tools
*   minor cleanups - the method names are now more consistent across classes

Last update: 2004-10-25 [SU]
*   added brace highlighting (partially based on code by Rob Goedman)
*   reversed declaration order of RQuartz copy operation: PDF first,
    TIFF second. This may help some PDF editors ... We may want to make this
    configurable and/or have two separate copy commands.

Last update: 2004-10-22 [SI]
*   added first embrional version of R preferences using AMPreferencePane class
    by Andreas Mayer. At the moment only color preferences are implemented.
    Quartz and misc preferences pane are there but not yet working.
    The preferences are still saved/loaded using NSDefaults
    You may need to "svn update" from the shell better than from inside of XCode
    
Last update: 2004-10-22 [SU]
*   newly typed text outside insertion scope is appended at the end (thanks to
    Byron for the idea)
*   converted InfoPlist.string to UTF-8 so it's easier to maintain and edit
*   added SVN build information to Info.plists and strings
*   removed BUILD_FOR_R_2_1_x flag and replaced by canonical version check
 
Last update: 2004-10-22 [SI]
*   fixed metric info problem with Quartz device. Apparently a leading pad was
    added to the textcontainer used to acquire the metric info. Thanks to Byron
    Ellys for this fix.
*   saveWorkSpaceFile fixed. It was impossible to create a new file.
*   introduced sourceOrLoadFile: in alternative to sourceFile. This is now connected to
    Source/Load button in the R Console Window toolbar.
*   added readFromFile method in RDocument to allow data loading with binary files. It allows
    also for drag and drop of image data on the R Icon
*   removed button from workspace browser window, added corresponding toolbar icon/button

Last update: 2004-10-21 [SI]
*   in data editor: the runModalForSession has been replaced by a modalForWindow
    to remove the problem with high CPU consuming (thanks to Byron Ellys for the fix)
*   column numbers instead of column names are used to identify columns (thanks to 
    Byron Ellys for the fix)

Last update: 2004-10-18 [SU]
*   fixed working directory selection
*   added sourceCurrentDocument: implementation; if the document is dirty,
    a temporary file is created, sourced and finally deleted

-- Release Version 1.00 - this revision is supplied with R 2.0.0 --

Last update: 2004-10-15 [SU]
*   code cleanups to get rid of most warnings
*   fixed linking issues caused by run_Rmainloop conflicting with R
*   fixed resizing behavior of the help window
*   disable continuous spell checking by default

Last update: 2004-10-14 [SU]
*   fixed output synchronization. all console output sources eventually
    use writeConsoleDirectly: and the insertion point is controlled by
    outputPosition.
*   add more flexible flush support (flushROutput and FlushStdConsole)
*   fixed document handling to be consistent with Cocoa; this means
    that menu items are handled implicitly by the first responder
    (where possible) and most default actions apply to the editor.
    Old versions of R GUI didn't have this, but mainly because there
    was no good editor supplied.
*   removed all global flags (IsRTF, IsREdit, ...)
*   toolbar icons changed (new icons added, some re-worked)
*   added menu+shortcut for "switch to console"
*   moved some menu items to logically more suitable places
    (e.g. "New document" is in "File" ...)
*   changed drop-document handling; the document is loaded in the editor
    (it can be easily executed by <Cmd><Enter> if necessary)
*   fixed activation of Quartz to use FR dispatching (this way it's not
    enabled in the console or editor where it doesn't make any sense)

Last update: 2004-10-13 [SI]
*   added support for activation of quartz device
    and creation of new quartz deivce from the GUI
    This functionality was present in the old Aqua GUI.
    
Last update: 2004-10-11 [SI]
*   first svn release

Last update: 2004-10-10 [SU]
*   fixed ?/help handling removed in the last update
*   fixed improper memory handling of external input
*   added queue to the console input to allow multiple simultaneous
    inputs while R is still working
*   fixed color handling - input text has now the correct color
*   added some constraints that prevent user from accidentally
    leaving the prompt area
*   fixed focus issues with the help window
*   don't unnecessarily repeat console input before commit
*   doProcessEvents: processes exactly one event in the blocking mode
*   added first release of R FAQ. To build it use [SI]
    makeinfo -D UseExternalXrefs --html --force --no-split RMacOSX-FAQ.texi
*   added "Docs" target to automatically build above FAQ
*   added sush dependency to R target - now it is possible to build
    the entire project from scratch by simply typing "xcodebuild"
    on the command line. Although it's the default, more precise
    specification of the target and build style can be used such as:
    xcodebuild -target R -buildstyle Deployment

Last update: 2004-10-09 [SU]
*   fixes in REngine (mem mgmt, 0 ptr fix); added executeString method
*   fixed package loading (use executeString and check the result)
*   huge cleanup of the R/Obj-C interface (stage 1). the interface is
    separated from RController by REPLHandler protocol. the R-side
    implementation is in Rcallbacks and RController implements the
    REPL protocol
*   changed output/console/prompt handling. this also makes sure that
    a prompt is always printed at the beginning of the line, no matter
    whether the previous output line is unfinished
*   raise the line buffer size from 1k to 32k, also it's not hard-coded now,
    but can be changed on the fly.
*   replace all evaluateString: with executeString: if the return value is
    not needed (ignoring the return value of eval.. causes memory leaks)
*   after history paste make textView the first respondent
    
Last update: 2004-10-08 [SI]
*   added toolbar colors icon and functionality. User can set font colors for
    the R Console window. Settings are saved automatically on exit. Just for
    fun: added also transparency of the R Console window.
*   console font size saved in the preferences
*   the color of the cursors is set to be the same as the prompt one

Last update: 2004-10-04 [SI]
*   fixed problem with applescript. Now uses scriptSuite and scriptTerminology
*   in sendIpunt: a fake keydown event is now generate to wake the event loop
    this is needed for both applescript and menu interaction
*   help(topic) and ?topic  are now handled internally and the help page is
    shown in the internal browser. 
    This is only a temporary solution. The correct approach is to create a
    new API to be called on each .show_help_on_topic_as_HTML call. Too late
    for release 2.0.0 of R.
*   Every call to Rengine evaluateString and parse causes R to be set in busy 
    state this allows for feedback to the user at any REngine use.
*   added support to save quartz device to PDF file. This is currently done
    using devcopy onto the pdf device. Native Cocoa methods like 
    [NSView dataWithPDFInsideRect] don't work at the moment because we don't
    use NSGraphicsContext. Should probably be done for the next release.
*   added clipboard copying into TIFF, PICT and PDF format
*   added support for printing of the graphics device, the console and the
    other editor windows
*   user input is now splitted in lines terminated by '\n'. This allows for
    copy and paste of bug documents. There's no limit to the input buffer
    apart from free memory. The input is just splitted in lines but if lines
    are longer than the maximum allowed by R (1024 currently) no action
    is taken, lines are just passed to R for at most 1024 bytes.

*   Opening file is either: load data or source a script whenever this is possible.
*   Implemented the internal editor via NSDocument class. R can open plain text and
    rtf files.
*   Implemented  file.show/R_ShowFiles.
*   Implemented  file.edit/R_EditFiles. FIXME: the file name is not correctly set
    at the moment for newly created document.

                            save R console, load file in editor

    (see: src/modules/aqua/aquaconsole.c)
*   In previous version Code Completion blocked R, now fixed.
*   Implemented the History and Logs drawers. Stdout/Stderr are redirected
    to the Logs drawer (still not asyncronously).

    paste the content of the item in the console at current cursor position
*   Implemented the tool bar for "stop", "quit", "history", "quartz" and "logs". Icons
    are horrible though.
*   added environment variable in info.plist
