Since: Version 20220101-133340-7edc5b5a

The functionality described in this section requires version 20220101-133340-7edc5b5a of wezterm, or a more recent version.

Returns the textual representation (not including color or other attributes) of the logical lines of text in the viewport as a string.

A logical line is an original input line prior to being wrapped into physical lines to composes rows in the terminal display matrix. WezTerm doesn't store logical lines, but can recompute them from metadata stored in physical lines. Excessively long logical lines are force-wrapped to constrain the cost of rewrapping on resize and selection operations.

If you'd rather operate on physical lines, see pane:get_lines_as_text.

If the optional nlines argument is specified then it is used to determine how many lines of text should be retrieved. The default (if nlines is not specified) is to retrieve the number of lines in the viewport (the height of the pane).

The lines have trailing space removed from each line. The lines will be joined together in the returned string separated by a \n character. Trailing blank lines are stripped, which may result in fewer lines being returned than you might expect if the pane only had a couple of lines of output.

To obtain the entire scrollback, you can do something like this:
