Description Patrick Lauer gentoo-dev

Right now emerge --search builds a list of search results, then prints all results at the end. This appears slow to users as it "stalls" while generating the results, then spews them at the end.

Printing each result as it is found should have much better interactivity and will appear faster even when it takes the same amount of time

I would like to develop a streaming API for the package description index file (see bug #525718). My plan is to search index file streams from all repos simultaneously, and to group together results for the same ${CATEGORY}/${PN} across all repositories.

My latest patch series from bug #525718 includes support for incremental display of search results:
