Overview ¶
Package pango provides a type-safe way to construct pango markup. Using nested Span and Text nodes, pango formatted output can be easily constructed with compile-time validation of nesting and automatic escaping.
For example, to construct pango markup for:
<span color="#ff0000">Red <span weight="bold">Bold Text</span></span>
the go code would be:
pango.New(
pango.Text("Red "),
pango.Text("Bold Text").Bold()).
Color(colors.Hex("#ff0000"))
or:
pango.Text("Red ").
Color(colors.Hex("#ff0000")).
Append(pango.Text("Bold Text").Bold())

Functions ¶
func AddIconProvider ¶
func AddIconProvider(name string, provider IconProvider)
AddIconProvider adds an icon provider for a given prefix. This is intended for use only by the pango/icons package. See "pango/icons".LoadFromFile for more details.
func SetUnitFormatter ¶
SetUnitFormatter sets the formatter to use in pango.Unit.
Types ¶
type IconProvider ¶
IconProvider is an interface for providing pango Icons. The function should return a pango node for the given icon name, or nil if an icon could not be found.
type Node ¶
type Node struct {
// contains filtered or unexported fields
}
Node represents a node in a pango "document".
func Icon ¶
Icon returns a pango node that displays the given icon. The identifier must be of the form $provider-$name, and the returned node will render the $name icon using $provider. e.g. "fa-add" will render the "add" icon using font awesome.
func Textf ¶
Textf constructs a text node by interpolating arguments. Note that it will escape both the format string and arguments, so you should use pango constructs to add formatting. i.e.,
Textf("<span color='%s'>%s</span>", "red", "text")
won't give you red text.
func (*Node) Append ¶
Append adds one or more nodes as children of the current node. The new nodes will inherit styles by virtue of being descendants, to insert them *adjacent* to the current node, use .Concat(...).
func (*Node) AppendText ¶
AppendText is a shortcut for Append(pango.Text(...), pango.Text(...), ...)
func (*Node) AppendTextf ¶
AppendTextf is a shortcut for Append(pango.Textf(...))
func (*Node) Background ¶
Background applies a background color and alpha.
func (*Node) Concat ¶
Concat adds the given nodes as siblings rather than children of the current node, and returns a wrapping node for further operations.
For example,
Text("c").Condensed().Color(red).Concat(Text("foo")).UnderlineError()
will create
<span underline='error'><span stretch='condensed' color='#ff0000'>c</span>foo</span>
where the appended "foo" is not condensed or red, and everything is underlined.
func (*Node) ConcatText ¶
ConcatText is a shortcut for Concat(pango.Text(...), pango.Text(...), ...)
func (*Node) ConcatTextf ¶
ConcatTextf is a shortcut for Append(pango.Textf(...))
func (*Node) ExtraCondensed ¶
ExtraCondensed sets the pango stretch to "extracondensed".
func (*Node) ExtraExpanded ¶
ExtraExpanded sets the pango stretch to "extraexpanded".
func (*Node) Larger ¶
Larger increases the font size of the contents by wrapping them in <big>...</big>
func (*Node) LetterSpacing ¶
LetterSpacing sets the letter spacing, in points.
func (*Node) NoStrikethrough ¶
NoStrikethrough sets the pango strikethrough to "false".
func (*Node) Rise ¶
Rise sets the font "rise" in pango units. Negative for subscript, positive for superscript.
func (*Node) SemiCondensed ¶
SemiCondensed sets the pango stretch to "semicondensed".
func (*Node) SemiExpanded ¶
SemiExpanded sets the pango stretch to "semiexpanded".
func (*Node) Smaller ¶
Smaller decreases the font size of the contents by wrapping them in <small>...</small>
func (*Node) StretchNormal ¶
StretchNormal sets the pango stretch to "normal".
func (*Node) Strikethrough ¶
Strikethrough sets the pango strikethrough to "true".
func (*Node) StrikethroughColor ¶
StrikethroughColor applies a strikethrough color.
func (*Node) StyleNormal ¶
StyleNormal sets the pango style to "normal".
func (*Node) UltraCondensed ¶
UltraCondensed sets the pango stretch to "ultracondensed".
func (*Node) UltraExpanded ¶
UltraExpanded sets the pango stretch to "ultraexpanded".
func (*Node) UltraLight ¶
UltraLight sets the pango weight to "ultralight".
func (*Node) UnderlineColor ¶
UnderlineColor applies an underline color.
func (*Node) UnderlineDouble ¶
UnderlineDouble sets the pango underline to "double".
func (*Node) UnderlineError ¶
UnderlineError sets the pango underline to "error".
func (*Node) UnderlineLow ¶
UnderlineLow sets the pango underline to "low".
func (*Node) UnderlineNone ¶
UnderlineNone sets the pango underline to "none".
func (*Node) UnderlineSingle ¶
UnderlineSingle sets the pango underline to "single".
func (*Node) VariantNormal ¶
VariantNormal sets the pango variant to "normal".
func (*Node) WeightNormal ¶
WeightNormal sets the pango weight to "normal".
