The YARRG system has two main parts: this website which maintains a searchable database of commodity prices, and an upload client, which screenscrapes the commodity data from the Puzzle Pirates game client and uploads it to the database.
You will need to upload data yourself if there is no data for your ocean or island, or the data that is there is too old. You should also upload when preparing trade run, as market conditions change and you want a plan based on recent data.
The current official version of YARRG for use as an upload client can browsed here: http://www.chiark.greenend.org.uk/~ijackson/ypp-sc-tools/master/ See particularly the YARRG README.
To install the client, install the "git" version control system and the other dependencies listed in the "Installation requirements" section of the README and then run:
git-clone http://www.chiark.greenend.org.uk/~ijackson/ypp-sc-tools/master/.git ypp-sc-tools cd ypp-sc-tools cd yarrg makethis will download the code into the directory
ypp-sc-tools
,
and build the software. (If your Linux is very up to date you may
find that it complains that it doesn't know the command git-core.
In that case, use git core, with a space, instead.)
When new versions of the upload client are released, you can:
cd .../ypp-sc-tools git-pull cd yarrg maketo fetch the new version. (Again, you may need git pull instead of git-pull.)
