# SPDX-License-Identifier: AGPL-3.0-or-later
# SYNOPSIS
# __jobrunner_sessions
# __jobrunner_sessions [<tool>]
#
# DESCRIPTION
# Parses `screen -ls` into machine-readable rows, one per active session:
# name, PID, state, and start time separated by tabs. Shared by jobrunner
# and its completions so both agree on what a session is named. Prints
# nothing when no sessions exist.
# Parses `tmux list-sessions` or `screen -ls` into machine-readable rows,
# one per active session: name, PID, state, and start time separated by tabs.
# Shared by jobrunner and its completions so both agree on what a session is
# named. Prints nothing when no sessions exist.
#
# EXIT STATUS
# 0 Parsed successfully (including the zero-session case)
# 1 screen is not installed
# 1 tool (tmux or screen) is not installed
#
# RETURNS
# One line per session: <name>\t<pid>\t<state>\t<started>
#
# EXAMPLE
# __jobrunner_sessions
# __jobrunner_sessions | string replace -r '\t.*$' ''

# screen -ls exits 1 when nothing is running; the parse handles that.

# Session rows are tab-indented and start with "<pid>.<name>".

or continue
# Trailing fields are parenthesized: "(<date>)\t(<state>)", and some
# screen builds omit the date, so read the state off the end.
