László Németh 391ea3bcb5 tdf#170177 cui offapi sw xmloff: hyphenate at constituent boundaries
Add new minimum character limit paragraph property to limit
hyphenation left to the compound constituent boundaries:

  com::sun::star::text::ParaHyphenationCompoundMinTrailingChars

– With the previous option for the hyphenation right to the
  constituent boundary, this new option allow to limit or disable
  hyphenation completely inside the compound constituents, or
  hyphenate only at constituent boundaries, with or without
  inside the suffix of the word or constituents;

– xmloff: add "no-limit" to loext:hyphenation-compound-push-char-count
  and loext:hyphenation-compound-push-char-count;

– "no-limit" values of this and the *LeadingChars option mean
  a maximum value. When both *LeadingChars and *TrailingChars
  got "no-limit", hyphenation before and inside the suffixes are
  forbidden, i.e. it is allowed only at constituent boundaries;

– textflowpage.ui: set max character count to 99, in both options;

– fix ParaHyphenationCompoundMinLeadingChars implementation for
  compound words with multiple constituents, when the middle word(s)
  are shorter, than the limit (e.g. Hungarian "tűz|kő|pattintás"
  wasn't hyphenated as "tűzkő-pattintás", only as "tűz-kőpattintás").

and commit c899d3608d
"tdf#158885 sw: don't hyphenate right after a stem boundary".

Schemas for Validating ODF Files

Schemas that can be used for validating ODF files

subdirs:

  • mathml2: W3C MathML 2.0 XML Schema (needed for Math embedded objects)
  • odf1.0, odf1.1, odf1.2: official OASIS RelaxNG schemas
  • odf1.3: current OASIS draft ODF 1.3 RelaxNG schema
  • libreoffice: draft ODF schema, with additional LO extensions

The extension schema in libreoffice/ is used by all unit tests if --with-export-validation is given, which is the default.

Notably this means that if you add a new feature to the ODF filters and you add the required unit test for the new feature, then most likely the test will fail with a complaint from the validator; in this case the schema needs to be updated to contain the new elements and attributes.

The extension schema uses the RelaxNG "include" feature to refer to the ODF schema; this means that it only contains those parts of the schema that actually need to be changed - this works well in many cases because the ODF schema is quite well structured with many named patterns, but unfortunately there are a few places where that isn't the case and large chunks needed to be copied to override them.

In the easy case, to add an attribute you just want to search for the corresponding element, which will have a "foo-attlist" named pattern, and then add another attribute like this:

<rng:define name="draw-enhanced-geometry-attlist" combine="interleave"> rng:optional <rng:attribute name="drawooo:sub-view-size"> <rng:ref name="string"/> </rng:attribute> </rng:optional> </rng:define>

Currently only the features that are actually exported in the unit tests have been added to the schema; there is still some work to do here to add everything; the crashtesting script also does ODF validation of all files and now also uses the custom schema.

Unfortunately it turned out that there are a lot of extensions already for which no proposal exists [1], and in many cases not even an entry on the Wiki [2], so clearly something like this extension schema is needed.
