That area is also a bit messy in KDevelop, and not something I use frequently 
myself. First of all, can you please be more specific what kind of template/
snippet you are using? We sadly have basically three different systems in 
place:

- new file template (#1)
- new project template (#2)
- text snippets to insert an open document (#3)

I assume here you are talking about the "snippets" plugin (#3), there the 
syntax would be:

```
${year()}
```

And you'll have to provide a javascript function like this in the `scripts` 
tab:

```
function year() { return new Date().getFullYear(); }
```

For project templates (#2), we rely on grantlee which is similar to django in 
spirit. There, the syntax would be something like

```
{% now "yyyy" %}
```

if I'm not mistaken.

The `<year>` token is only replaced for file templates (#1).
