# "gen" command

“**gen**” is the standard command commonly used to generate code in the scope of the **current model** and the **current bundle of templates**.

{% hint style="info" %}
You must have defined the **current model** and the **current bundle** \
before using the **gen** command.\
The Telosys prompt must look like this: `telosys#(model-name)[bundle-name]>`
{% endhint %}

## "gen" command syntax

```
> gen *|entities *|templates [-r] [-y]
```

* **`entities`** : a **list of entities** (part of the name) separated by a comma (,) or **"\*"** for all
* **`templates`** : a **list of templates** (part of the name) separated by a comma (,) or **"\*"** for all
* **`-r`**  (optional) to copy the **static resources** provided by the bundle (if any)
* **`-y`**  (optional) to force "**yes**" answer (to avoid confirmation)
