"""
Class for parsing the `/usr/sbin/corosync-cmapctl [params]` command.
All lines are stored in the dictionary with the left part of the equal
sign witout parenthese info as the key and the right part of equal sign
as the value.
Typical output of the command is::
config.totemconfig_reload_in_progress (u8) = 0
internal_configuration.service.0.name (str) = corosync_cmap
internal_configuration.service.0.ver (u32) = 0
internal_configuration.service.1.name (str) = corosync_cfg
internal_configuration.service.1.ver (u32) = 0
internal_configuration.service.2.name (str) = corosync_cpg
internal_configuration.service.2.ver (u32) = 0
Examples:
>>> type(corosync)
<class 'insights.parsers.corosync_cmapctl.CorosyncCmapctl'>
>>> 'internal_configuration.service.0.name' in corosync
True
>>> corosync['internal_configuration.service.0.name']
'corosync_cmap'
Raises:
SkipComponent: When there is no content
ParseException: When there is no "=" in the content
