After including the use of glib we might as well replace inih with the glib key file parser. All configuraiton file parsing has been reworked and also the options parsing has been cleaned up, resulting in better and stricter configuration file and option value checks. Compared to old, configuration files now requires any default configurations to be put in a group/section named [default]. Configuration file keywords such as "enable", "disable", "on", "off", "yes", "no", "0", "1" have been retired. Now only "true" and "false" apply to boolean configuration options. This is done to simplify things and avoid any confusion. The pattern option feature has been reworked so now the user can now access the full match string and any matching subexpression using the %mN syntax. For example: [usb devices] pattern = usb([0-9]*) device = /dev/ttyUSB%m1 Then when using tio: $ tio usb12 %m0 = 'usb12' // Full match string %m1 = 12 // First match subexpression Which results in device = /dev/ttyUSB12
