#  irc — catgirl wrapper for managing IRC network connections
#
#  Usage:
#    irc                     Show all networks by category
#    irc <network>           Connect to a network
#    irc <network> -j #ch    Connect and join extra channel
#    irc search <term>       Search networks by name/host
#    irc help                Show usage
#
#  Config: ~/.config/catgirl/<network>
#  Each file is a catgirl config (host, port, nick, join, etc.)

# ─── Network Categories ──────────────────────────────────────
#
# Networks are grouped by purpose. Add new catgirl configs to
# ~/.config/catgirl/ and register them in the appropriate
# category array below.
#
# Tracker networks are organized by content domain so you can
# quickly find the right channel for interviews, recruitment,
# or community participation.

# ── Trackers: Gateway & Recruitment ───────────────────────────
# These are the entry points into the private tracker ecosystem.
# RED and OPS interviews happen here. Build ratio, reach Power
# User, and recruitment threads open the doors to everything.

TRACKERS_GATEWAY="red ops"

# ── Trackers: Cinema & Arthouse ───────────────────────────────
# Channels for film-focused trackers. BakaBT covers anime film.
# KG and PTP recruitment happens via RED/OPS Power User forums,
# not directly on IRC — but these are the community channels.

TRACKERS_CINEMA="bakabt"

# ── Trackers: Literature & Books ──────────────────────────────
# MAM interviews happen Wed & Sat on their IRC. IRChighway and
# Undernet are direct download channels — use @search to find
# books, bot sends via DCC. Essential for rare/OOP titles.

TRACKERS_LITERATURE="mam irchighway undernet"

# ── Trackers: Music & Live Recordings ─────────────────────────
# DimeADozen is the bootleg concert recording community.
# RED/OPS double as music tracker IRC (see Gateway above).

TRACKERS_MUSIC="dime"

# ── General Networks ──────────────────────────────────────────
# Communities for programming, science, privacy, and general
# IRC culture. These are not tracker-related.
