libgdata

libgdata is a GLib-based library for accessing online service APIs using the GData protocol — most notably, Google's services. It provides APIs to access the common Google services, and has full asynchronous support.

See the test programs in gdata/tests/ for simple examples of how to use the code.

libgdata is API and ABI stable.

Dependencies

• glib-2.0 ≥ 2.44.0
• libxml-2.0
• gio-2.0 ≥ 2.44.0
• libsoup-2.4 ≥ 2.42.0
• liboauth ≥ 0.9.4
• json-glib ≥ 0.15.0

If compiling with --enable-gnome (for GNOME support):

• gcr-base-3
• goa-1.0 ≥ 3.8

If compiling the demos:

• gtk+-3.0 ≥ 2.91.2

Environment variables

If the environment variable LIBGDATA_DEBUG is set to one of the following values, libgdata will give debug output (at various levels):

• 0: Output no debug messages or network logs
• 1: Output debug messages, but not network logs
• 2: Output debug messages and network traffic headers
• 3: Output debug messages and full network traffic logs, redacting usernames, passwords and auth. tokens
• 4: Output debug messages and full network traffic logs, and don't redact usernames, passwords and auth. tokens

If LIBGDATA_DEBUG is unset, no debug output will be produced.

So, to debug a program which uses libgdata, run it from a terminal with the following command:

LIBGDATA_DEBUG=3 ./my-program-name &> libgdata.log

Deprecation guards

If LIBGDATA_DISABLE_DEPRECATED is defined when compiling against libgdata, all deprecated API will be removed from included headers.

Default branch renamed to main
