László Németh 6e8819f29b tdf#132599 cui offapi sw xmloff: add hyphenation-keep-type
Support XSL attribute "column" and CSS 4 attribute "spread",
stored in loext:hyphenation-keep-type, to give better control
over hyphenation-keep. E.g. spread: both parts of a hyphenated
word shall lie within a single spread, i.e. when the next page
is not visible at the same time (e.g. the next page is not a
right page of a book).

– css::style::ParaHyphenationKeep is a boolean property now,
  importing hyphenation-keep = "page" as true.

– type of ParaHyphenationKeep, including the new non-ODF types
  is stored in the new ParagraphProperties::ParaHyphenationKeepType.

– default value of ParaHyphenationKeepType is COLUMN for
  interoperability.

– Add checkboxes to Text Flow -> Hyphenation Across in
  paragraph dialog:

  * Column (previously: Hyphenate across column and page)
  * Page
  * Spread

  – enabling/disabling them follows XSL/CSS 4/loext, i.e.
    possible combinations:

  * No Hyphenation across
    (hyphenation-keep = "page" and loext:hyphenation-keep-type = "column")

  * Hyphenation across [x] Column
    (hyphenation-keep = "page" and loext:hyphenation-keep-type = "page")

  * Hyphenation across [x] Column [x] Page
    (hyphenation-keep = "page" and loext:hyphenation-keep-type = "spread")

  * Hyphenation across [x] Column [x] Page [x] Spread
    (hyphenation-keep = "auto")

– Add ODF import/export

– Update DOCX import

– Add ODF unit tests

Note: recent implementation depends on widow settings: disabling widow
handling allows hyphenation across columns and pages not only in table
cells.

Note: RTF import-only, but not used bPageEnd has been renamed to bKeep.
Depending on the RTF test results, likely it will need to disable
the layout change, e.g. GetKeepType()=ParagraphHyphenationKeepType::AUTO,
if PageEnd uses obsolete hyphenation rule, i.e. shifting only the
hyphenated word to the next page, not the full line.

More information:

– COLUMN (standard XSL value, defined in
  https://www.w3.org/TR/2001/REC-xsl-20011015/slice7.html#hyphenation-keep)

– SPREAD and ALWAYS (CSS 4 values of hyphenate-limit-last,
  equivalent of hyphenation-keep, defined in
  https://www.w3.org/TR/css-text-4/#hyphenate-line-limits).

Follow-up to commit 9574a62add
"tdf#132599 cui offapi sw xmloff: implement hyphenate-keep" and
commit c8ee0e8f58
"tdf160518 DOCX: import hyphenation-keep to fix layout".

Edit Engine

In OpenOffice.org build DEV300m72 this module was split off from svx but it has no dependencies on svx (nor on sfx2) while in turn svx depends on editeng

If you build LibreOffice with dbgutil, you have some extended debug keys:

  • Ctrl+Alt+F1 - draws the paragraph rectangles in different colors
  • Ctrl+Alt+F11 - toggles dumping the edit engine state to the "editenginedump.log" on draw
  • Ctrl+Alt+F12 - dumps the current edit engine state to "editenginedump.log"
