func IsInsertable ¶
IsInsertable tells whether a character is insertable into the buffer or not.
Types ¶
type Buffer ¶
type Buffer struct {
Config *config.Config
// The path to the file and its type.
Path string
FileType support.FileType
// The buffer's lines and condition.
Lines []Line
IsDirty bool
IsReadOnly bool
// The cursor's position. The Y value must always be decremented by one when
// accessing buffer elements since the editor's title bar occupies the first
// row of the screen. CursorDX is the cursor's X position, with compensation
// for extra space introduced by rendering tabs.
CursorX int
CursorDX int
CursorY int
// The viewport's column and row offsets.
OffsetX int
OffsetY int
}
