Zellij has no live-stream facility like tmux pipe-pane, so capture is a one-shot 'zellij action dump-screen --full' run from a fish_exit handler (conf.d/zellij-logging.fish -> functions/_zellij_dump_log.fish). The C5 guard is checked inside the helper at exit time, so toggling logging needs no sync_logging coordination — there is no persistent stream. Extract pruning into functions/_prune_terminal_logs.fish, shared by both the tmux and zellij helpers. This also fixes a latent bug in the tmux helper: globbing tmux_*.log directly errored with 'No matches for wildcard' on the first log in an empty dir. The shared helper globs via 'set' (tolerates no-match) and uses command ls/rm to bypass the eza and trash C1 shadows.

# SYNOPSIS
|
|
# _prune_terminal_logs <prefix>
|
|
#
|
|
# DESCRIPTION
|
|
# Removes the oldest "<prefix>_*.log" files in SCROLLBACK_HISTORY_DIR
|
|
# (default ~/.terminal_history) so the total count for that prefix stays
|
|
# within SCROLLBACK_HISTORY_MAX_FILES (default 100). Files are sorted by
|
|
# modification time, so the most recently written logs are kept — actively
|
|
# appended logs (e.g. a tmux pipe-pane stream) survive.
|
|
#
|
|
# Uses `command ls`/`command rm` to bypass the C1 shadows: the bare `ls` is
|
|
# the eza wrapper, which injects OSC-8 hyperlink escapes into paths, and the
|
|
# bare `rm` is the trash wrapper. The glob is expanded via `set` first so a
|
|
# no-match (empty dir / first run) yields an empty list instead of a hard
|
|
# "No matches for wildcard" error.
|
|
#
|
|
# ARGUMENTS
|
|
# prefix Log-name prefix to prune (e.g. tmux, zellij)
|
|
#
|
|
# RETURNS
|
|
# 0 Always
