[tracecompass-dev] Txt parser to custom analysis
Hi,

I am trying to create an overview of the states of several components in a system. For this I want to use a timeGraphView of TraceCompass.

The input trace is a text file file which i parse using a custom parser. I filtered out a Timestamp (2016-07-28 09:25:45.037), a field named Origin (a string) and a event_type (Closed, Closing....). The event should trigger a state change defined in my stateProvider


The parser:
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<CustomTxtTraceDefinitionList>
<Definition category="Custom Text-xml" name="xml">
<TimeStampOutputFormat>yyyy-MM-dd HH:mm:ss.SSS</TimeStampOutputFormat>
<InputLine>
<Cardinality max="2147483647" min="0"/>
<RegEx>\t+.*\t+(\d\d\d\d-\d\d-\d\d \d\d:\d\d:\d\d.\d\d\d)+\t([a-zA-Z]*\t)+ReportStateChange.[a-zA-Z]*\s-&gt;\s(.[a-zA-Z]*).*</RegEx>
<InputData action="" format="yyyy-MM-dd HH:mm:ss.SSS" name="Timestamp" tag="TIMESTAMP"/>
<InputData action="" format="" name="Origin" tag="OTHER"/>
<InputData action="" format="" name="Event type" tag="EVENT_TYPE"/>
</InputLine>
<OutputColumn name="Timestamp" tag="TIMESTAMP"/>
<OutputColumn name="Origin" tag="OTHER"/>
<OutputColumn name="Event type" tag="EVENT_TYPE"/>
</Definition>
</CustomTxtTraceDefinitionList>


The parser is ok, but i cannot get the connection between the filtered fields and analysis which is defined as:

        <entry path="Tasks/*">
<display type="self" />
        </entry>
    </timeGraphView>
</tmfxml>

My questions:
Is this the right place to ask these questions?
Is it possible using a text input trace to create the graph I want?
How can i get the state provider to use the events coming from the custom text parser?

Thanks,

Johan
