func EncoderOptions added in v0.23.0 

func EncoderOptions(level term.Level) []diferenco.EncoderOption

EncoderOptions returns diferenco.EncoderOption slice with appropriate color configuration based on the terminal's color level.

func SetDiffTheme added in v0.23.0 

func SetDiffTheme(theme DiffTheme)

SetDiffTheme sets the current diff theme.

Types

type DiffTheme added in v0.23.0 

type DiffTheme struct {
	Dark  map[color.ColorKey]string
	Light map[color.ColorKey]string
}

DiffTheme defines color scheme for diff output.

type Pager 

type Pager struct {
	// contains filtered or unexported fields
}

Pager represents a simple terminal pager built with viewport. It implements io.Writer and must be closed to display content.

func NewPager 

func NewPager(colorMode term.Level, useAltScreen bool) *Pager

NewPager creates a new pager with given color mode and alt screen setting. The pager implements io.Writer, content is accumulated via Write calls. Close must be called to display the content in the pager. useAltScreen controls whether to use alternate screen buffer (default true).

func (*Pager) Close 

func (p *Pager) Close() error

Close finalizes the pager and displays the content. For short content that fits in the terminal, it outputs directly without starting the pager. For longer content, it starts an interactive pager with viewport. Close is idempotent - calling it multiple times is safe.

func (*Pager) ColorMode 

func (p *Pager) ColorMode() term.Level

ColorMode returns the color mode of the pager.

func (*Pager) Write 

func (p *Pager) Write(data []byte) (int, error)

Write implements io.Writer interface for the pager. It appends data to the internal buffer and returns an error if the pager is closed.

type StringObject added in v0.23.0 

type StringObject string

StringObject implements viewport.Object for a single line

func (StringObject) GetItem added in v0.23.0 

func (s StringObject) GetItem() item.Item
