/*
|

|
|
Can be used as part of an update script to automatically create a patch
|
||
|
|
hardcoding the path of all GSettings schemas in C code.
|
||
|
|
For example:
|
||
|
|
passthru = {
|
||
|
|
hardcodeGsettingsPatch = makeHardcodeGsettingsPatch {
|
||
|
|
inherit src;
|
||
|
|
schemaIdToVariableMapping = {
|
||
|
|
...
|
||
|
|
};
|
||
|
|
};
|
||
|
|
|
||
|
|
updateScript =
|
||
|
|
let
|
||
|
|
updateSource = ...;
|
||
|
|
updatePatch = _experimental-update-script-combinators.copyAttrOutputToFile "evolution-ews.hardcodeGsettingsPatch" ./hardcode-gsettings.patch;
|
||
|
|
in
|
||
|
|
_experimental-update-script-combinators.sequence [
|
||
|
|
updateSource
|
||
|
|
updatePatch
|
||
|
|
];
|
||
|
|
};
|
||
|
|
}
|
||
|
|
takes as input a mapping from schema path to variable name.
|
||
|
|
For example `{ "org.gnome.evolution" = "EVOLUTION_SCHEMA_PATH"; }`
|
||
|
|
hardcodes looking for `org.gnome.evolution` into `@EVOLUTION_SCHEMA_PATH@`.
|
||
|
|
All schemas must be listed.
