Common configuration files

This page sketches out a design for configuration files that can be read from and written to by libsigrok, and used by various frontends.

• All applications should take -C argument.
  • If filename, load config from filename.
  • Else load standard config file and use argument as section name.
• Use default $XDG_CONFIG_HOME/sigrok or ~/.config/sigrok config directory
• Syntax GKeyFile:
  • [sections]
  • # comments
  • key = value
  • liberal with whitespace,
• <application>.conf
• Store fixed settings in [default] section.
  • Put here only by apps that can do something like "save config", "remember settings" -- and only if the user specifically selects such a function.
• Store last used settings in [last] section.
• Can store decoder settings.
• Keys are sr_config_info id string.
• Example settings:

driver = atten-pps3xxx
conn = /dev/ttyUSB1
ocp = on
output_channel = independent
output_voltage_max[CH1] = 12.00
output_current_max[CH1] = 0.020
output_enabled[CH1] = yes
