# batocera-settings can mimic batoceraSettings.py
|
||
|
|
# goal: abolish this python script, it's useless for the sake of the load feature only
|
||
|
|
# get a more user friendly environment for setting, getting and saving keys
|
||
|
|
#
|
||
|
|
# Usage of BASE COMMAND:
|
||
|
|
# longform: <filename> --command <cmd> --key <key> --value <value>
|
||
|
|
#
|
||
|
|
# shortform: <file> <cmd> <key> <value>
|
||
|
|
#
|
||
|
|
# --command load write enable disable status
|
||
|
|
# --key any key in distribution.conf (kodi.enabled...)
|
||
|
|
# --value any alphanumerical string
|
||
|
|
# use quotation marks to avoid globbing use slashes escape special characters
|
||
|
|
|
||
|
|
# This script reads only 1st occurrence if string and writes only to this first hit
|
||
|
|
#
|
||
|
|
# This script uses #-Character to comment values
|
||
|
|
#
|
||
|
|
# If there is a boolean value (0,1) then then enable and disable command will set the corresponding
|
||
|
|
# boolean value.
|
||
|
|
|
||
|
|
# Examples:
|
||
|
|
# 'batocera-settings --command load --key wifi.enabled' will print out 0 or 1
|
||
|
|
# 'batocera-settings --command write --key wifi.ssid -value "This is my NET"' will set 'wlan.ssid=This is my NET'
|
||
|
|
# 'batocera-settings enable wifi.ssid' will remove # from configfile (activate)
|
||
|
|
# 'batocera-settings disable wifi.enabled' will set key wifi.enabled=0
|
||
|
|
# 'botocera-settings /myown/config.file --command status --key my.key' will output status of own config.file and my.key
