Hi Caolán,
* Sidenote - Initially I tried using CharClass::titlecase() but
discovered this doesn't actually work.
What did you try and what went wrong ?
There appears to be an issue with
class cclass_Unicode where "trans" is only ever set to
"Transliteration_casemapping" and there is no mechanism to set it to
"Transliteration_titlecase".
I believe that the casemapping thing there knows about upper, lower and
title case and uses setMappingType to MappingTypeToTitle to toggle which
one to return
e.g. I added this test
http://cgit.freedesktop.org/libreoffice/core/commit/?id=eb9b8ebca49291797e655b50f64af2c2fa03434c
to confirm to myself that its working like I think its supposed to.
When I called CharClass::titlecase() I expected "ORAN" to be changed to
"Oran" but from memory the returned string was still "ORAN". Attached is
the back trace I took at the time.
Looking again in cclass_Unicode::toTitle()
http://opengrok.libreoffice.org/xref/core/i18npool/source/characterclassification/cclass_unicode.cxx#92
I see only the first character in each word is Title cased and the rest
are left untouched. Oh!
105 for (sal_Int32 i = nPos; i < nCount + nPos; i++, out++) {
106 if (i >= bdy.endPos)
107 bdy = brk.nextWord(Text, bdy.endPos, rLocale,
108 WordType::ANYWORD_IGNOREWHITESPACES);
109 *out = (i == bdy.startPos) ?
110 trans->transliterateChar2Char(Text[i]) : Text[i];
111 }
I just checked and your test case passes when sTest = "Some text" but if
I change it to sTest = "Some tExt" it fails (assuming "Some Text" is the
right result).
The following function appears to do what I originally wanted (i.e.
Title case the first character and Lower case subsequent characters) but
using opengrok I can't find anywhere that actually instantiates this class.
rtl::OUString SAL_CALL Transliteration_titlecase::transliterate()
http://opengrok.libreoffice.org/xref/core/i18npool/source/transliteration/transliteration_body.cxx#329
Anyway, I think the solution I used in my patch is better as I actually
wanted Sentence case rather than Title case for the overall string.
Cheers,
Brad
