A Compare / Diff of reports tool is on our roadmap.
But until that feature is built, it may be easier / faster for development to have the full and custom documentation available in a more friendly format (likely as an export) for that so that at least for now you can do the compare / diff yourself.
Can you provide us with a sample of what you’d like it to look like?
Initially I’d think it would be a simply formatted text report with heading lines that give the DIFF tools some reference anchor points. The anchors would need to be consistent between different reports (comparing similarly named reports), and between generations (for comparing report revisions).
A PDF formatted report would work, but the PDF diff tools are harder to come by.
An XML formatted report would work for text diff or custom apps, and possibly also facilitate migrating reports from CR to another system.
A basic report would list visible blocks of fields, text and graphics with positioning and attribute info, formulas. A full report would dump all CR report options.
Personally I use NotePad++ compare but recommend another (FOSS) tool to work with your reports.
Though we’ll officially announce tomorrow, pleased to let you know that you can now do this!
You can now save the documentation (initially implemented on Full Documentation) in one of 3 formats:
Of course for your purposes, you’ll want to probably use Text so that it’s easier to compare in the tools you mentioned. We’re working on adding this to the Custom Documentation and with the effort we’re now much closer to having a native diff / compare (hint hint) coming soon.
