GUI: Improve workaround for scrollbar bug.

[gnumeric.git] / BUGS

   To report Gnumeric bugs, please visit bugzilla.gnome.org.

    This file is used as a scratch pad by developers.  It is a list of known
issues that need to be addressed.  Divided into, things that will prevent
release, and longer term bugs.

-------------------------------------------------------------------------------

Release Critical
----------------
    - hidding col/row headers should not hide outline symbols
    - header selection broken when there are groups

In Progress
-----------
    Jody
        - xlsx chart axis export
        - data slicers
        - CELL translation & array handling
        - INDEX range res, iteration
        - ExprEntry extensions
        - Tool to filter dups
        - python wrapper for libspreadsheet
        - mis-export of array expr
            http://bugzilla.gnome.org/show_bug.cgi?id=322096

    : s/range_equal/gnm_range_eq/

Review
------
    - func name translation             {Manny}
    - merge libgda port

Target Features
---------------
- insert cut
- clipboard handlers in plugins
- load/save of external references
- all the merged cell singleton bugs
- scripting

Short term goals
----------------
    - Use go_glade_signal_connect (and friends)
    - ={A1:A3+rand()}   only calls rand() once.

Misc stuff that should be fixed
-------------------------------

- Missing undo/redo for
    - Freeze panes (tricky this is a view attribute)
    - `Add Scenario' Portion of Solver
 
- cols/rows
    : Make unhide smarter to find hidden regions on either side of
      selected ranges.
    : drag based col/row resize should support negative sizes to
      correspond to hiding.
    : support delete for discontinuous ranges

Worries
-------
    : range_translate in stf.c looks suspicous.
    : Add bounds checking of integers on the xml based importers
    : do bounds check in excel_get_text
    : Select graph, Copy, and paste to Emacs: used to crash, but now it
      just g_barfs and pastes empty string.

    - Create new type string/double/int (not bool) for BIN2DEC etc.
    - Allow missing arguments that are not '?' for ACCRINT.

    - TestForBiffConsumer : #REF ??
    - accrint-test.xls : why fail ?
    - BAHT functions
    - broken-name.xls
    - database_test.xls
    - div0-xp.xls
    - edward~1.xls
    - eng.xls
        - XL returns real numbers as strings from complex functions
        - Check difference in besseli
    - errors.xls
        : calc of interest
        : #REF on sheet2
    - extract-clean-new.xls : loss of data in col A ?
    - furigana.xls : #NAME?
    - global_calling_placeholder.xls
    - named-expr-95.xls
    - named-expr-97.xls
    - operand.xls
    - pivot-edited.xls : odd colours in the 'the range that contains' box
    - store and persist view modes
    - fix bogosity of 'ant' cursors being in sheet_view and having the app contact them.

10) Functions
    - Function range_min_k uses an O(n*log n) algorithm.  It should use O(n)
      algorithm, see Knuth.
    - Suport >100 style for SUBTOTAL
    - docs
        : Make 'func is foo compatible' a flag on the importers
        : need conventions for including markup
            - simple bold/italic/font
            - links
            - embedded images ??
    - Support parsing and displaying locale specific function names.
    - When loading a function that already has a definition (such as a stub),
      we're in trouble: (a) we just overwrite the old definition in the symbol
      table, (b) both old and new owner want to remove the symbol on exit.

      We should somehow steal the old definition (and complain unless the old
      was a stub) without changing the GnmFunc address.  On exit we should
      explicitly check that it is ours to remove.
    - examples
        1) A registry of named data tables to reference from examples
        2) The example text should have the expr in C locale
                ?? how to reference the sample data ??
    : HARMEAN with no arguments (or just strings/booleans) should yield N/A,
      not NUM.
    : MAXA,MINA with no arguments should yield N/A, not NUM.
    : STDEVPA,VARPA with no arguments should yield VALUE, not DIV0.
    : STDEVA,VARA with 0-1 arguments should yield DIV0, not VALUE.
    : DEVSQ with no arguments should yield #NUM, not zero.
        ? How did you enter this.  xl-2k refuses to parse that
        ! Import from a .csv file.

    : tie the custom ui into action sensitivity pools
    : support array evaluation for =LARGE and friends

autoformat
----------
    - leaking styles when an edge is disabled
    - consider either using the users data as a sample, or at least making the
      sample adaptive based on which edges are disabled.

auto-fill
---------
    - The autocalc label should use a more readable format and should not get
      clipped.

    - Names
        : references in names do not get changed with cut/paste or ins/del row/col.
          How to handle relative references in names ?? here.
        : Dialog
            * We should start with the expr entry set to either the current cell,
              or by selecting the first named expression in scope that contains the
              current cell.
        : Handle pasting an expression with an un-qualified sheet local name into
          another sheet

    - clean up the range_list codes to differentiate a list of ranges from a list
      of cellranges.

    - The max row/col canvas scroll size is still hard coded.

    - let's add simple commands like inc/dec font size and things like that.

    - Auto resize needs to handle empty cells.

    - Styles
        : improve uniform_get to handle full sheet more quickly.
        : Borders
            * use new border code for cell format dialog (possibly preview-grid)

Import/Export
-------------
    : Look into octave/matlab filters
    : look into maxima
    : Talk to shaunm about mathematica

Clipboard
---------
    - May be not export html as table when just one cell is selected.

General Ideas
-------------
    - A connection to swivel (www.swivel.com)
    - Sugar/OLPC UI & collab
    - Add 'send a frown/smile' button
    - 'fish eye' zoom to around selection
    - treemap for hierarchical data
    - conditional / computed formats
        : referenced styles (eg for time sheets)
        : GnmColor computable to move the calculated aspect into the actual
          selectors
    - 'Custom' autofilter type to eval expr per cell
    - autofilter : refresh
    - macro hook in validation to run proc if valid
