Description

When I try to change the settings via gsettings or creating local.d settings (/etc/dconf/db/local.d/) files nothing happens or paths are non existent.

gsettings get com.github.amezin.ddterm bold-color
No such schema “com.github.amezin.ddterm”

If I look in dconf it states:
No schema available. A schema is what describes the use of a key, and Dconf Editor can't find one associated with this key. If the application that was using this key has been uninstalled, or if this key is obsolete, you may want to erase it.

I believe this the problem why gsettings cannot set the values.

However, this works:

dconf write /com/github/amezin/ddterm/scrollback-unlimited false

GNOME Shell extensions have schemas file(s) inside the extension installation directory, in schemas subdirectory.

There is gsettings --schemadir ... option and GSETTINGS_SCHEMA_DIR environment variable exactly for this case.

For system-wide installation (i. e. as a distro-specific package, or sudo make install) it's possible to install the schemas file into the default system-wide schemas directory (usually /usr/share/glib-2.0/schemas), but currently it's not performed.

After migration to meson build system #648 schemas will be installed into /usr/share/glib-2.0/schemas for system-wide installation.
