Can anyone please help me understand NSTextStorage attributes.Let say we have an attributed bold text which looks like this:bold{
NSColor = "Generic RGB colorspace 1 1 1 1";
NSFont = "\"OpenSans-Bold 16.00 pt. P [] (0x100cca530) fobj=0x100f2d710, spc=4.16\"";
NSParagraphStyle = "Alignment 4, LineSpacing 0, ParagraphSpacing 8, ParagraphSpacingBefore 16, HeadIndent 0, TailIndent 0, FirstLineHeadIndent 0, LineHeight 26/0, LineHeightMultiple 0, LineBreakMode 0, Tabs (\n 28L,\n 56L,\n 84L,\n 112L,\n 140L,\n 168L,\n 196L,\n 224L,\n 252L,\n 280L,\n 308L,\n 336L\n), DefaultTabInterval 0, Blocks (\n), Lists (\n), BaseWritingDirection -1, HyphenationFactor 0, TighteningForTruncation YES, HeaderLevel 0 LineBreakStrategy 0";
}After editing, it looks like thisbold{
NSColor = "Generic RGB colorspace 1 1 1 1";
NSFont = "\"OpenSans-Bold 16.00 pt. P [] (0x100cca530) fobj=0x100f2d710, spc=4.16\"";
NSParagraphStyle = "Alignment 4, LineSpacing 0, ParagraphSpacing 8, ParagraphSpacingBefore 16, HeadIndent 0, TailIndent 0, FirstLineHeadIndent 0, LineHeight 26/0, LineHeightMultiple 0, LineBreakMode 0, Tabs (\n 28L,\n 56L,\n 84L,\n 112L,\n 140L,\n 168L,\n 196L,\n 224L,\n 252L,\n 280L,\n 308L,\n 336L\n), DefaultTabInterval 0, Blocks (\n), Lists (\n), BaseWritingDirection -1, HyphenationFactor 0, TighteningForTruncation YES, HeaderLevel 0 LineBreakStrategy 0";
}a{
NSColor = "Generic RGB colorspace 1 1 1 1";
NSFont = "\"OpenSans-Bold 16.00 pt. P [] (0x100cca530) fobj=0x100f2d710, spc=4.16\"";
