Several fields in GoReleaser's config file support templating.
Those fields are often suffixed with `_template`, but sometimes they may not
be. The documentation of each section should explicit in which fields
templating is available.
On fields that support templating, this fields are always available:
| Key | Description |
| :------------: | :----------------------------------------------: |
| `.ProjectName` | the project name |
| `.Version` | the version being released (`v` prefix stripped) |
| `.Tag` | the current git tag |
| `.Commit` | the git commit hash |
| `.Major` | the major part of the version |
| `.Minor` | the minor part of the version |
| `.Patch` | the patch part of the version |
| `.Env` | a map with system's environment variables |
| `.Date` | current UTC date in RFC3339 format |
| `.Timestamp` | current UTC time in Unix format |
On fields that are related to a single artifact (e.g., the binary name), you
may have some extra fields:
| Key | Description |
| :-------------: | :-----------------------------------: |
| `.Os` | `GOOS` (usually allow replacements) |
| `.Arch` | `GOARCH` (usually allow replacements) |
| `.Arm` | `GOARM` (usually allow replacements) |
| `.Binary` | Binary name |
| `.ArtifactName` | Archive name |
On all fields, you have these available functions:
| Usage | Description |
| :-----------------: | :--------------------------------------: |
| `time "01/02/2006"` | current UTC time in the specified format |
With all those fields, you may be able to compose the name of your artifacts
pretty much the way you want:
```yaml
example_template: '{{ .ProjectName }}_{{ .Env.USER }}_{{ time "2006" }}'
```
For example, if you want to add the go version to some artifact:
```yaml
foo_template: 'foo_{{ .Env.GOVERSION }}'
```
And then you can run:
```console
GOVERSION_NR=$(go version | awk '{print $3;}') goreleaser
```
> Note that those are hypothetical examples and the fields `foo_template` and
> `example_template` are not valid GoReleaser configurations.
