Peter Rajnoha	2078b842fb	libdm: report: add dm_report_set_selection ... Since we can do repeated dm_report_output calls now, we also like to be able to set selection for each of these outputs.	2016-06-20 11:33:43 +02:00
Peter Rajnoha	9c8f912ea7	libdm: report: introduce dm_report_group ... This patch introduces DM report group (represented by dm_report_group structure) that is used to group several reports to make a whole. As a whole, all the reports in the group follow the same settings and/or formatting used on output and it controls that the output is properly ordered (e.g. the output from different reports is not interleaved which would break readability and/or syntax of target output format used for the whole group). To support this feature, there are 4 new functions: - dm_report_group_create - dm_report_group_push - dm_report_group_pop - dm_report_group_destroy From the naming used (dm_report_group_push/pop), it's clear the reports are pushed onto a stack. The rule then is that only the report on top of the stack can be reported (that means calling dm_report_output). This way we make sure that the output is not interleaved and provides determinism and control over the output. Different formats may allow or disallow some of the existing report flags controlling output itself (DM_REPORT_OUTPUT_*) to be set or not so once the report is pushed to a group, the grouping code makes sure that all the reports have compatible flags set and then these flags are restored once each report is popped from the report group stack. We also allow to push/pop non-report item in which case such an item creates a structure (e.g. to put several reports together with any opening and/or closing lines needed on output which pose as extra formatting structure besides formatting the reports). The dm_report_group_push function accepts an argument to pass any format-specific data needed (e.g. handle, name, structures passed along while working with reports...). We can call dm_report_output directly anytime we need (with the only restriction that we can call dm_report_output only for the report that is currently on top of the group's stack). Or we don't need to call dm_report_output explicitly in which case all the reports in a stack are reported on output automatically once we call dm_report_group_destroy.	2016-06-20 09:26:51 +02:00
