2017-09-20Implement CFDE_TextEditEngine::GetIndex* methods.Dan Sinclair
This CL adds unittests and implementations for the text edit engine methods to get various indexes based on cursor position. The |RebuildPieces| method was fixed to correctly keep track of character position when dealing with BIDI characters.

2017-09-20Convert FindNextBreakPos to return positionDan Sinclair
This CL changes FindNextBreakPos to return the found index instead of requiring a call to GetAt(). This also fixes the issue that we may return -1 from GetAt which would cause issues in the BoundsForWordAt method when it gets shoved into a size_t variable.

2017-09-19Invert flag to CFDE_TextEditEngine::Iterator::IsEOFDan Sinclair
This CL changes the IsEOF flag to match the semantics of the FindNextBreakPos flag.

2017-09-19Convert selection to use count instead of end indexDan Sinclair
This CL changes the Text Edit Engine code to use a count instead of an end index for the selection range. Using count lets us differentiate a selection at the beginning of 1 character and an empty selection. A few new tests were added to test unicode word break behaviour, some are not working yet and are commented out.

2017-09-18Convert string class namesRyan Harrison
Automated using git grep & sed. Replace StringC classes with StringView classes. Remove the CFX_ prefix and put string classes in fxcrt namespace. Change AsStringC() to AsStringView(). Rename tests from TEST(fxcrt, *String*Foo) to TEST(*String*, Foo). Couple of tests needed to have their names regularlized.

2017-08-30Rebuild CFDE_TextEditEngine.Dan Sinclair
This CL rebuilds the text edit engine in a simpler fashion. Instead of depending on multiple pages, paragraphs and buffer fields there is a single text edit engine which contains a gap buffer. This makes the code easier to understand and follow.
