Pango Text Attribute Markup 3 Pango Library Pango Text Attribute MarkupSimple markup language to encode text plus a PangoAttrList Frequently, you want to display some text to the user with attributes applied to part of the text (for example, you might want bold or italicized words). With the base Pango interfaces, you could create a #PangoAttrList and apply it to the text; the problem is that you'd need to apply attributes to some numeric range of characters, for example "characters 12-17." This is broken from an internationalization standpoint; once the text is translated, the word you wanted to italicize could be in a different position. The solution is to include the text attributes in the string to be translated. Pango provides this feature with a small markup language. You can parse a marked-up string into the string text plus a PangoAttrList using the function pango_parse_markup(). A simple example of a marked-up string might be: "<span foreground="blue" size="100">Blue text</span> is <i>cool</i>!" The root tag of a marked-up document is <markup>, but pango_parse_markup() allows you to omit this tag, so you will most likely never need to use it. The most general markup tag is <span>, then there are some convenience tags. <span> has the following attributes: font_desc A font description string, such as "Sans Italic 12"; note that any other span attributes will override this description. So if you have "Sans Italic" and also a style="normal" attribute, you will get Sans normal, not italic. font_family A font family name face Synonym for font_family size Font size in 1000ths of a point, one of the absolute sizes 'xx-small', 'x-small', 'small', 'medium', 'large', 'x-large', 'xx-large', or one of the relative sizes 'smaller' or 'larger'. style One of 'normal', 'oblique', 'italic' weight One of 'ultralight', 'light', 'normal', 'bold', 'ultrabold', 'heavy', or a numeric weight variant 'normal' or 'smallcaps' stretch One of 'ultracondensed', 'extracondensed', 'condensed', 'semicondensed', 'normal', 'semiexpanded', 'expanded', 'extraexpanded', 'ultraexpanded' foreground An RGB color specification such as '#00FF00' or a color name such as 'red' background An RGB color specification such as '#00FF00' or a color name such as 'red' underline One of 'single', 'double', 'low', 'none' rise Vertical displacement, in 10000ths of an em.
