Package gnofly is the market of gnofly's planes: a fixed-price book where a plane's owner lists it, anyone buys it, and each sale pays the planes realm's royalty (RoyaltyInfo: 5% to the gnofly treasury) out of the price.
It is a wrapper, not a collection: it mints nothing. The planes are the tokens of gno.land/r/g1t2kg2vtr3fukg43eujkn6x53gfdyakhngt4sfd/gnofly/nfts/planes, moved with that realm's TransferFrom. A seller first approves this realm there (Approve for one plane, or SetApprovalForAll); List then moves the plane here, in escrow, Buy hands it to the buyer and Cancel back to the seller.
Its calls and reads have the shapes Bazaar's site (bazaar.gnomi.fun) uses on a collection package (List, UpdatePrice, Cancel, Buy, Transfer; ListOpen, ItemLine, TokensOf, Minted), so that it can be registered there later, under the slug of its last path element. It is not registered, and pays Bazaar nothing.
It is version v0 of the market (the path's v0). SetPaused stops new listings for a move to a newer one; Cancel and Buy keep working, so no plane is ever stuck here.
Every write is a direct call from a wallet: no realm can list, buy or cancel in a user's name.
Buy buys a listed plane: send exactly its price in ugnot. The royalty of the planes realm (RoyaltyInfo: 5% to the gnofly treasury) is paid out of the price, the seller receives the rest, and the plane goes to the buyer. It works while the market is paused.
Cancel takes a listing down and gives the plane back to its seller. It works while the market is paused.
ItemLine returns the line of plane id, listed or not. It panics for an id that is not a minted plane: Bazaar's site skips the ids it cannot read.
List puts plane id up for sale at priceUgnot. The caller must own it and have approved this realm on the planes realm (Approve for this plane, or SetApprovalForAll): the plane moves here, in escrow, until it is bought or the listing is cancelled.
ListOpen returns the listings, one line each, in id order, at most 50.
Minted returns how many planes were minted.
Name and Symbol are the planes collection's: the market sells nothing else.
Paused reports whether new listings are stopped.
Render shows the listings on gnoweb.
ReturnStray gives back a plane this realm holds outside any listing: one someone sent here by mistake. Admin of the game realm only; to is who it came from, as the chain's transfer events show.
SetPaused stops (or resumes) new listings and price changes. Admin of the game realm only. Cancel and Buy keep working, so a move to a newer market never strands a plane: sellers cancel here and list there.
TokenURI returns the image of a plane, an https URL.
TokensOf returns the ids of the planes owner holds, comma-separated, in id order: "3,42,700". A listed plane is not among them: it is held here.
Transfer gives a plane the caller owns, not listed, to another address, through this realm: the call Bazaar's site makes. It needs the same approval as List. A plane can always be moved on the planes realm itself.
UpdatePrice changes the price of a plane the caller listed.
