As the label suggests, you can write any command line argument of the comparator tool here. Each argument should be on its own separate line. The available arguments can be seen in the comparator help message (you can see this message when running comparator with the --help argument).

On top of the normal arguments, there is also a type of macro system. This macro system is powerful and can be used for making the link dynamic. These macros represent each part of the split job name (split by the spliterator) and when loading the report page, they are replaced by it.

The macros have this syntax:

• "%{x}", where you replace x with a number corresponding with the xth split part of the job's name (indexing starting with 1). It will be replaced with that part.
• "%{N-y}", where you replace y with a number corresponding for the yth split part of the job's name from the BACK. It will be replaced with that part. Entering just "%{N}" will be replaced with the last part of the name.
• "%{S}" or "%{SPLIT}" will be replaced with the spliterator specified in the field above.

Example of the macros:
For the job name "jtreg~full-jp11-ojdk11~rpms-f36.x86_64-fastdebug.sdk-f36.x86_64.testfarm-x11.defaultgc.legacy.lnxagent.jfroff",
and spliterator set to "[.-]", the macros "%{2}%{S}%{N-1}_something_%{N}" will be replaced with "jp11[.-]lnxagent_something_jfroff".

So an example of the whole prompt with arguments can look like this:
--compare
--history 5
--build-config-find changelog.xml:nvr:/build/nvr
--nvr ".*"
--formatting html
--regex %{1}%{S}%{2}%{S}%{3}%{S}.*%{S}%{5}%{S}%{6}%{S}%{7}%{S}.*%{S}%{9}%{S}%{10}%{S}%{11}%{S}%{12}%{S}%{13}%{S}%{14}%{S}%{15}
