## Deprecate an option and replace it with a new one
|
||
|
|
|
||
|
|
The `deprecated` keyword argument can now take the name of a new option
|
||
|
|
that replace this option. In that case, setting a value on the deprecated option
|
||
|
|
will set the value on both the old and new names, assuming they accept the same
|
||
|
|
values.
|
||
|
|
|
||
|
|
```meson
|
||
|
|
# A boolean option has been replaced by a feature with another name, old true/false values
|
||
|
|
# are accepted by the new option for backward compatibility.
|
||
|
|
option('o1', type: 'boolean', value: 'true', deprecated: 'o2')
|
||
|
|
option('o2', type: 'feature', value: 'enabled', deprecated: {'true': 'enabled', 'false': 'disabled'})
|
||
|
|
|
||
|
|
# A project option is replaced by a module option
|
||
|
|
option('o3', type: 'string', value: '', deprecated: 'python.platlibdir')
|
||
|
|
```
