gnomesearchclient 0.1.1

A Python package for interacting with Gnome search providers without using Gnome Shell

PyGnomeSearchClient

PyGnomeSearchClient is a Python package for interacting with Gnome search providers outside the Gnome Shell environment. This package is targeted mostly at users of compositors with custom widgets, especially Ignis since that's what I currently use.

Rationale

Gnome search providers provide a simple-to-use API for searching various apps on the system but is currently limited to use on Gnome Shell. Even without Gnome Shell installed or running, most apps that provide search providers still register their search provider interfaces on DBus and still place their search configuration files in deterministic places, meaning that a different app could interact with them. This package aims to create a wrapper around the DBus calls used to interact with the providers.

Gnome search providers are fairly widely used. On my system, the installed search providers are:

• Files (Nautilus)
• Boxes
• Calendar
• Cartridges
• Clocks
• Firefox (broken?)
• Passwords and Keys (Seahorse)
• Qalculate-gtk!
• Settings
• Software
• Web (Epiphany)

Any of these, in isolation, could be easily coded into a desktop UI framework, but maintaining dozens of different search providers becomes taxing. Additionally, adding a new provider does not mean changing your dotfiles at all. Rolling your own search provider is also fairly simple, requiring only that a DBus service be registered and a config file be placed in some location.

Usage

Documentation

Gnome search providers place an ini file in one of a number of locations, generally /usr/share/gnome-shell/search-providers if installed globally. The file has the structure:

[Shell Search Provider]
DesktopId=xxx.desktop
BusName=xxx.SearchProvider2 (generally)
ObjectPath=/xx/xxx/SearchProvider
Version=2

The DBus interface is described by Gnome here, but the gist of it is that, under the bus name above, providers register methods GetInitialResultSet, GetSubsearchResultSet, GetResultMetas, ActivateResult, and LaunchSearch. This package provides wrappers for these methods and collects search providers while optionally maintaining state information.
