## Members

- `from` (method): Starts at a line, counted from the top of the visible area.
- `fromStartOfHistory` (method): Starts at the oldest line tmux still has.
- `to` (method): Ends at a line, counted the same way as {@link #from}.
- `toEndOfHistory` (method): Ends at the newest line, including anything below the visible area.
- `withEscapeSequences` (method): Keeps the escape sequences that colour and position the text.
- `escapingNonPrintable` (method): Writes anything unprintable as an octal escape rather than dropping it.
- `joiningWrappedLines` (method): Joins a line tmux wrapped back into the one line it was.
- `preservingTrailingSpace` (method): Keeps the spaces at the end of a line, which tmux otherwise drops.
- `trimmingTrailingSpace` (method): Drops trailing space and the empty lines below the content. Requires tmux 3.4.
- `fromAlternateScreen` (method): Reads the alternate screen, which is what a full-screen program draws on.
- `pendingOnly` (method): Reads only output tmux has not drawn yet.
- `fromModeScreen` (method): Reads what a mode is showing rather than the pane beneath it. Requires tmux 3.6.
- `withHyperlinks` (method): Keeps hyperlink markers. Requires tmux 3.7.
- `withLineNumbers` (method): Prefixes each line with its number. Requires tmux 3.7.
