### CONFIGURATION
#
# Declarations here you can customize to your preferred setup.
# Generally only if you actually have to. Check Wiki for details.
#
###

# Filename of the CMI Sqlite3 database. Default: cmi.sqlite.db
CMIdb="cmi.sqlite.db"

# Maximum results returned. Default: 10
CMIdbMax="10"

# No need to edit this one, unless you really want to check a specific username.
findUser="$1"

# Url to query uuid with
findUrl="https://namemc.com/search?q="

# Do we use the UUID or IGN? Default: true
# When set to true, it will use the uuid, set to false to use the ign
CMICmdUuid=true

# Use tmux to send cmi info to session? Default: false
tmuxEnabled=false

# Name of tmux session, in case you dont use mcserver (default of 1MB-minecraft.sh)
tmuxSession="mcserver"

# When tmuxEnabled=true, send 'cmi info'? Default: true
CMICmdInfo=true

# When tmuxEnabled=true, send 'cmi checkaccount'? Default: false
CMICmdCheckAccount=false

# Alternative for checkaccount? Handy for mass kick or ban, etc. Default: checkaccount
# Warning: If you dont know what this means, leave it, because there's no undo button.
CMICmdAlternative="checkaccount"

# When tmuxEnabled=true, send 'cmi stats'? Default: false
CMICmdStats=false

# When tmuxEnabled=true, send 'cmi homes'? Default: false
CMICmdHomes=false

# If tmux is enabled, delay between commands? value requires NUMBER[SUFFIX]
# Default is "1s", set to "0s" to disable.
tmuxDelay="1s"
    # The NUMBER may be a positive integer or a floating-point number.
    # The SUFFIX may be one of the following:
    # s - seconds, m - minutes, h - hours, d - days

# Debug mode off or on? Default: false (true means it spits out progress)
_debug=false

### FUNCTIONS AND CODE
#
# ! WE ARE DONE, STOP EDITING BEYOND THIS POINT !
#
###

# If tmux is enabled, and we do multiple commands, stack with an extra delay?
# Default is "1s", set to "0s" to disable. Value requires NUMBER[SUFFIX]
tmuxDelayStack="0.2s"
    # The NUMBER may be a positive integer or a floating-point number.
    # The SUFFIX may be one of the following:
    # s - seconds, m - minutes, h - hours, d - days
