v0.52.0 - `send_keys()` updates

libtmux 0.52.0

capture_pane() enhancements

The Pane.capture_pane() method now supports 5 new parameters exposing additional tmux capture-pane flags:

Parameter	tmux Flag	Description
escape_sequences	-e	Include ANSI escape sequences (colors, attributes)
escape_non_printable	-C	Escape non-printable chars as octal \xxx
join_wrapped	-J	Join wrapped lines back together
preserve_trailing	-N	Preserve trailing spaces at line ends
trim_trailing	-T	Trim trailing empty positions (tmux 3.4+)

Examples

Capturing colored output:

# Capture with ANSI escape sequences preserved
pane.send_keys('printf "\\033[31mRED\\033[0m"', enter=True)
output = pane.capture_pane(escape_sequences=True)
# Output contains: '\x1b[31mRED\x1b[0m'

Joining wrapped lines:

# Long lines that wrap are joined back together
output = pane.capture_pane(join_wrapped=True)

Version compatibility

The trim_trailing parameter requires tmux 3.4+. If used with an older version, a warning is issued and the flag is ignored. All other parameters work with libtmux's minimum supported version (tmux 3.2a).
