Enumeration Type Documentation

◆ ExpandoPadType

enum ExpandoPadType

Padding type.

Padding occurs between two sides, left and right. The type of Padding, soft or hard, refers to how the left-hand-side will react if there's too little space.

Hard padding: The left-hand-side will fixed and the right-hand-side will be truncated. Soft padding: The right-hand-side will be fixed and the left-hand-side will be truncated.

Enumerator
EPT_FILL_EOL	Fill to the end-of-line.
EPT_HARD_FILL	Hard-fill: left-hand-side will be truncated.
EPT_SOFT_FILL	Soft-fill: right-hand-side will be truncated.

Definition at line 43 of file node_padding.h.

{
  EPT_FILL_EOL,     
  EPT_HARD_FILL,    
  EPT_SOFT_FILL,    
};

◆ ENPad

enum ENPad

Names for the Padding's children.

Padding has two children: Left and Right.

Enumerator
ENP_LEFT	Index of Left-Hand Nodes.
ENP_RIGHT	Index of Right-Hand Nodes.

Definition at line 55 of file node_padding.h.

{
  ENP_LEFT,           
  ENP_RIGHT,          
};
