Hossein acc008c660 Add asserts to make sure the calculation is correct 
On Linux/gcc (Ubuntu 10.3.0-1ubuntu1~20.04), I was getting this
warning:

sc/source/core/data/bcaslot.cxx:647:25: warning: comparison of
unsigned expression in ‘>= 0’ is always true [-Wtype-limits]
  647 |             assert(slot >= 0 && slot < mnBcaSlots);
      |                    ~~~~~^~~~

slot variable is of type SCSIZE, which is defined as size_t in
sc/inc/address.hxx.

This is fixed in 405a7a0955. To make
sure the calculation of slot is OK, I have added these 2 asserts:

    assert(nRow >= rSD.nStartRow);
    assert(nCol >= rSD.nStartCol);

Spreadsheet Application Code

You can dump some information in a dbgutil build:

Shortcuts

CTRL+SHIFT+F12

Dumps the column width of the first 20 columns.

CTRL+SHIFT+F11

Dumps the graphic objects and their position and size in pixel.

CTRL+SHIFT+F6

Dumps the SfxItemSet representing the cell properties' of the current selection as a xml file. The file will be named dump.xml

The Cache Format

ScDocument::StoreTabToCache allows storing the content (not the formatting) of a table to a binary cache format.

The format is column orientated which allows quick serialization of the table.

  • Header:

    • Number of Columns: 64 bit unsigned integer

  • Column:

    • Column Index: 64 bit unsigned integer
    • Column Size: 64 bit unsigned integer
    • For each cell type block a new ColumnBlock

  • ColumnBlock:

    • Start Row: 64 bit unsigned integer
    • Block Size: 64 bit unsigned integer
    • Type: 8 bit unsigned integer
      • 0 : empty
      • 1 : numeric
        • for each cell: 64 bit IEEE 754 double precision value
      • 2 : string
        • for each cell: 32 bit signed string length followed by string length bytes of the string (UTF-8)
      • 3 : formula
        • for each cell: 32 bit signed string length followed by the formula in R1C1 notation as a string

Functions Supporting Wildcards or Regular Expressions

As this comes up every now and then, and rather should be documented in an extra list of the Help system, functions that support Wildcards or Regular Expressions and depend on the setting under Tools -> Options -> Calc -> Calculate are those that in ODF OpenFormula (ODFF) are defined to depend on the HOST-USE-REGULAR-EXPRESSIONS or HOST-USE-WILDCARDS properties, see https://docs.oasis-open.org/office/v1.2/os/OpenDocument-v1.2-os-part2.html
