1998-09-21  Miguel de Icaza  <miguel@nuclecu.unam.mx>

	* src/expr.c (do_expr_decode_tree): When decoding a tree, include
	the argument separator.  Also, loop properly trough the arguments
	being decoded.

	(function_call_with_values, function_def_call_with_values): New
	functions: these ones are for the plugins so that a plugin can
	invoke other functions in Gnumeric.

	* src/fn-date.c (gnumeric_now): The serial number returned by
	NOW() should be relative to 1900/1/1, not year zero.

1998-09-20  Miguel de Icaza  <miguel@nuclecu.unam.mx>

	* src/expr.c (eval_expr): Fix the way we computed expressions.

	* src/eval.c (cell_eval): Maintain a CELL_ERROR flag to know if
	the value is NULL due to an error or to the cell not being
	evaluated.

	* src/expr.c (funcion_call_with_values): Add a routine to allow
	plugins to call other functions defined in Gnumeric.

	* src/style.c: Handle the pattern property of the styles.

	* src/style.h: Pattern style is now just a 4 bit quantity, instead
	of a RefCounted structure.

	* src/plugin.c: Include gnumeric-util.h

1998-09-19  Miguel de Icaza  <miguel@nuclecu.unam.mx>

	* src/item-cursor.c (item_cursor_do_drop): Use button-1 to select
	an option on the popup menu.

	* src/fn-date.c: New file, implements various date and time
	manipulation routines.

	* src/main.c: Accept --dump-func-defs flag to dump the help
	available for our built in functions.

	* src/symbol.c: Export the symbol hash table.

1998-09-19  Miguel de Icaza  <miguel@nuclecu.unam.mx>

	* src/format.c (render_number): Use the locale provided rendering
	number.  This will require translators to also translate correctly
	the default formats for their locale.

1998-09-19  Miguel de Icaza  <miguel@nuclecu.unam.mx>

	* src/format.c (split_time): New code that works correctly
	in the range expected by Microsoft Excel [1900,1900+65535].  We of
	course work on a wider range than Excel can.  We can work on
	pre-1900 dates and on 1900+2^31 dates, but it might make little sense.

1998-09-18  Miguel de Icaza  <miguel@nuclecu.unam.mx>

	* src/item-cursor.c (item_cursor_autofill_event): Accept pending
	input when the user autofills.

	* README, Doc/Design: Updated

	* configure.in: autoconf tests for python.

	* src/sheet-autofill.c (sheet_autofill_dir): Only fill the region
	we were requested.

into gnumeric string values.

1998-09-17  Tom Dyas  <tdyas@vger.rutgers.edu>

        * plugins/sample/plugin-sample.c: Update to the new plugin API.

        * src/plugin.c (plugin_load,plugin_unload): Replaced g_print's
        with gnumeric_notice. Call new API function "can_unload" to see if
        a plugin is still in use.

        * src/plugin.h: New API function "can_unload". Removed refcount.

Python, do something like:

import gnumeric

# Simple function to add two numbers.
def foobar(a,b):
  return a + b

gnumeric.register_function("adder", "ff", foobar)

Use Makefile.temp to compile the plugin for now until detection of Python
path is put into configure.in. Python code will be
loaded from ~/.gnumeric/main.py so stick the above Python code snippet
in that file to see it run.

1998-09-17  Miguel de Icaza  <miguel@nuclecu.unam.mx>

	* src/sheet-view.c (sheet_view_row_size_changed,
	sheet_view_col_size_changed): If there is a selection of columns
	or rows, change the sizes of all of the columns.

	* src/sheet.c (sheet_row_get_distance, sheet_col_get_distance):
	optimized to be O(n) instead of O(n^2) using
	(col_row_distance): new routine to compute distances.

	* src/sheet-view.c (sheet_view_redraw_cell_region): Add the

	initialize the ->pixels field.

	the command line.  Drop requirement for --file option.

	* src/sheet-object.c (sheet_object_destroy): Keep track of the
	sheet->objects structure.
	(sheet_object_create_line, sheet_object_create_filled): Keep track
	of the sheet->objects structure.
	(sheet_object_realize, sheet_object_unrealize): Export these
	functions.
	(sheet_object_destroy): Keep track of the sheet->objects structure

	stuff like "Product1" -> "Product2", ...

1998-09-16  Miguel de Icaza  <miguel@nuclecu.unam.mx>

	* src/cursors.c (cursors_shutdown): Fix bug.  Destroy the ith

	autofill_create_fill_items):  Better type compatible routine.
	This is required for the list fill type.
	(autofill_init): startup the autofill code.  It registers a number
	of default lists (weekdays and months for now).

2) recalc worksheets on load

1998-09-15  Tom Dyas  <tdyas@vger.rutgers.edu>

        * src/plugin-manager.c: Changed where the Remove button was made
        sensitive so that it actually sync's with the list selection.

1998-09-16  Miguel de Icaza  <miguel@nuclecu.unam.mx>

	* src/workbook.c: Use the new accelerator setup from
	gnome-app-helper.

Autofill lists work:

	Integers, Floats, Formulas and constant strings works.

Todo:

	Lists of known strings and strings with numbers embedded

Miguel.

Got cursors working.

Use the cursors properly on the spreadhseet (gives good feedback
on what is going to happen).

More work on autofill.

miguel.

Color attributes in formats work (ie, you can get colored cells now);

My first -futile attempts- at getting various different cursors working on the
spreadsheet (we need a cross and various other cursors for a better emulation
of Excel).

The beginning of autofill, but I really need to see Excel live before implementing
this.

Miguel.
