better createContext APIs with setters, and no default values, in Typescript. this is documented in https://github.com/typescript-cheatsheets/react-typescript-cheatsheet/blob/master/README.md#context
// create context with no upfront defaultValue
// without having to do undefined check all the time
function createCtx<A>() {
const ctx = React.createContext<A | undefined>(undefined)
function useCtx() {
const c = React.useContext(ctx)
if (!c) throw new Error("useCtx must be inside a Provider with a value")
return c
}
return [useCtx, ctx.Provider] as const

Automatically unlock KeePass database with GNOME Keyring

(Tested with KeePassXC on Fedora 25)

By default when using GNOME Keyring you have a keyring that is unlocked when you log in (usually called "Login"). You can make use of that by storing a KeePass database password in this keyring and using it to automatically unlock your KeePass database.

Store the KeePass database password in GNOME Keyring. You'll have to set a label and at least one attribute/value pair. The label is displayed in a GNOME keyring manager (e.g. Seahorse), the attribute/value pair should be a unique identifier because it's needed for the lookup. I suggest to use keepass as attribute and the database name as value (make sure it doesn't contain any spaces).

secret-tool store --label="KeePass <database_name>" keepass <database_name>

Then create a script to launch and immediately unlock your KeePass database.
