# Extensions
|
|
|
|
|
|
|
|
|
|
You can publish libraries (also known as packages or extensions)
|
|
|
|
|
that users can then add to their scripts. These typically
|
|
|
|
|
provide a driver for a particular hardware device you can connect
|
|
|
|
|
to a microbit.

|
Packages can be published from the pxt command line. We are still sorting out the details.

|
|
|
## Localizing libraries
|
|
|
|
|
|
|
|
|
|
It is possible to package localization strings for the **jsDoc** description associated to the API in the package.
|
|
|
|
|
|
|
|
|
|
When compiling a package, the PXT compiler generates a `strings.json` file under the `_locales/` folder.
|
|
|
|
|
This file contains a map from the symbol name to the en
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
{
|
|
|
|
|
...
|
|
|
|
|
"basic": "Provides access to basic micro:bit functionality.",
|
|
|
|
|
...
|
|
|
|
|
}
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
{
|
|
|
|
|
"basic.clearScreen": "Eteint toutes les diodes."
|
|
|
|
|
}
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
```

_locales/fr/strings.json
