Hossein ea5641baee Updated README.md files to represent current code / use Markdown format 
Previously, all of the README files have been renamed to README.md
and now, the contents of these files were changed to use Markdown
format. Other than format inconsistency, some README.md files lacked
information about modules, or were out of date. By using LibreOffice
/ OpenOffice wiki and other documentation websites, these files were
updated. Now every README.md file has a title, and some description.
The top-level README.md file is changed to add links to the modules.
The result of processing the Markdown format README.md files can be
seen at: https://docs.libreoffice.org/

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
