You can get an approximation to what you want. Some scripting/grepping/similar tools/skills needed. There's one called jq that eats JSON files, which is what ED log files are. It is good for quick extraction of data, but does require that you know the data and what it contains. I run jq in Windows or Linux environments. (See
https://jqlang.github.io/jq/download/ and
https://jqlang.github.io/jq/manual/ )
How: Identify all entry stars that were found by autodiscovery and were previously undiscovered
by you. With jq, this is
jq -r 'select(.ScanType == "AutoScan" and has("StarType") and .WasDiscovered == false and .DistanceFromArrivalLS == 0) | .StarSystem' <input file>
The select() expression defines what you are looking for, and the '| .StarSystem' prints the system name of the star(s) that match(es). The '-r' option makes jq print strings 'raw' instead of making them into JSON strings with quotes and all ...
This is only an approximation as: 1) if you get a MauveAdder error during jump to a multi-star system, you usually don't get the entry star autoscanned,
2) you may not return alive with the exploration data to Universal Cartopraphics, which is what registers it as discovered by you.
It may be possible to identify 1-situations, and to extract the StarSystem name for those in a separate pass. 2-situations require much more analysis.
It would be simpler to use EDDiscovery, but as I don't have much luck with its search expression, I have personally given up on that. Perhaps someone else can provide suggestions for that.
(Added: You don't invoke jq for each separate file: you concatenate the log files to one single 'all_logs.log', and let jq loose on that.)
(Added more: There may be a 3). I don't know exactly what makes ED regard a system as discovered. If it is scanning the entry star only, there is no 3). But if it is 'all stars in system' corresponding to a honk, multi-star systems will not be detected by the search expression above.)
(Added: 4) The WasDiscovered value was introduced after 2019 and before early 2021. Earlier logs can't be used (as far as known) for 'I discovered this'. ) Similarly, autoscan (AutoDiscovery) was introduced after the game was published: logs from versions that did not have autodiscovery (or 'scan' command) won't be useful either.
