# Code autocompletion in SourceCraft Code Assistant
{% note info %}
The interface language of the Visual Studio Code plugin depends on the selected IDE language.
{% endnote %}
The smart autocompletion mode explicitly supports code autocompletion for the following programming languages and frameworks:
* C++
* Go
* Java
* JavaScript/TypeScript
* Kotlin
* Python
* Scala
* SQL
* Swift
Autocompletion may also work for other languages. For languages that are less represented in public repositories, the number and quality of autocompletion prompts will be lower.
## Use case {#examples}
In this example, we use the [_insert_](#insert) mode to revise the code, and then, the [_replace_](#replace) mode, which provides suggestions for the next lines based on the edits we made:
Here, after we have changed the argument name, the _replace_ mode updates it accordingly in the other lines:
## Insert mode {#insert}
The _insert_ mode in Code Assistant can suggest the most suitable options to complete the current line or word.
Code Assistant analyzes your code context and provides the following types of suggestions:
* Automatic.
* User-triggered (**Ctrl** + **Space**). In Visual Studio Code, you can also use **Ctrl** + **Enter**.
1. Open the IDE and create a test file named `server.cpp` with the following contents:
```cpp
// simple web-server to work with sockets
#include
#include
#include
#include
#include
using namespace std;
int main() {
}
```
1. In the `int main()` section, start typing something, e.g., `//create socket`. See the Code Assistant suggestion:
```cpp
...
int main() {
//create socket
int sockfd = socket(AF_INET, SOCK_STREAM, 0);
}
```
1. Select an action for the suggestion:
{% list tabs group=ide %}
- Visual Studio Code {#vscode}
* Click **Tab** to accept the suggestion.
* To start accepting the suggestion word by word, press **Ctrl** + **→** for Windows or Linux or **Command** + **→** for macOS.
* To discard the suggestion, press **Esc**.
* If there are multiple suggestions, you can switch between them using **Alt** + **[** and **Alt** + **]** for Windows or Linux or **Option** + **[** and **Option** + **]** for macOS.
- JetBrains IDE {#jb}
* Click **Tab** to accept the suggestion.
* To discard the suggestion, press **Esc**.
{% endlist %}
You can also watch our Code Assistant video tutorial [here](https://sourcecraft.dev/portal/code-assistant/).
## Replace mode {#replace}
The _replace_ mode in Code Assistant can suggest corrections and renaming options in the current file code based on the changes you have made.
1. Open the IDE and create a test file named `fibonacci.py` with the following contents:
```py
def fibonacci(k):
if k == 0:
return 0
elif k == 1:
return 1
else:
return fibonacci(k-1) + fibonacci(k-2)
print(fibonacci(10))
```
1. For example, change the variable name from `k` to `n`. See the Code Assistant corrections:
```py
def fibonacci(n):
if n == 0:
return 0
elif n == 1:
return 1
else:
return fibonacci(n-1) + fibonacci(n-2)
print(fibonacci(10))
```
Code Assistant suggests corrections line by line. Move the cursor to the relevant line to see a correction from Code Assistant.
1. Select what to do with the suggestion:
* Click **Tab** to accept the suggestion.
* To discard the suggestion, press **Esc**.
The model takes code revision history into account. Depending on this history, the suggestions may vary significantly.
## Suggestion indicator {#help-indicator}
When generating a suggestion, the loading icon will appear to the left of the editable code. If generation stops or there is no result, you will see the (no suggestion) icon.
The suggestion indicator is enabled by default.
To enable or disable the indicator:
{% list tabs group=ide %}
- Visual Studio Code {#vscode}
1. In the left-hand panel, click .
1. In the panel that opens, select **Settings**.
1. Navigate to **Autocompletion**.
1. In the settings window that opens, enable or disable the **Code Assistant suggestion indicator** and **Code Assistant load indicator**.
- JetBrains IDE {#jb}
1. In the top-right corner, click and select **Settings...**.
1. In the left-hand column, select **SourceCraft Code Assistant**.
1. Enable or disable **Disable suggest indicator**.
1. To save the settings, click **Apply**.
