title: Name Templates
---

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),<br>or `{{ .Tag }}-SNAPSHOT-{{ .ShortCommit }}` in case of snapshot release |
| `.Tag`         | the current git tag                                                                                                          |
| `.ShortCommit` | the git commit short hash                                                                                                    |

| `.GitURL`      | the git remote url                                                                                                           |
| `.Major`       | the major part of the version (assuming `Tag` is a valid semver, else `0`)                                                   |
| `.Minor`       | the minor part of the version (assuming `Tag` is a valid semver, else `0`)                                                   |

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)  |
| `.Mips`         | `GOMIPS` (usually allow replacements) |
| `.Binary`       | Binary name                           |
| `.ArtifactName` | Archive name                          |
| `.ArtifactPath` | Relative path to artifact             |

On the NFPM name template field, you can use those extra fields as well:

| Key        | Description                  |
|------------|------------------------------|
| `.Release` | Release from the nfpm config |
| `.Epoch`   | Epoch from the nfpm config   |

On all fields, you have these available functions:

| Usage                   | Description                                                                                                                    |
|-------------------------|--------------------------------------------------------------------------------------------------------------------------------|
| `replace "v1.2" "v" ""` | replaces all matches. See [ReplaceAll](https://golang.org/pkg/strings/#ReplaceAll)                                             |
| `time "01/02/2006"`     | current UTC time in the specified format                                                                                       |
| `tolower "V1.2"`        | makes input string lowercase. See [ToLower](https://golang.org/pkg/strings/#ToLower)                                           |
| `toupper "v1.2"`        | makes input string uppercase. See [ToUpper](https://golang.org/pkg/strings/#ToUpper)                                           |
| `trim " v1.2  "`        | removes all leading and trailing white space. See [TrimSpace](https://golang.org/pkg/strings/#TrimSpace)                       |
| `dir .Path`             | returns all but the last element of path, typically the path's directory. See [Dir](https://golang.org/pkg/path/filepath/#Dir) |
| `abs .ArtifactPath`     | returns an absolute representation of path. See [Abs](https://golang.org/pkg/path/filepath/#Abs)                               |

With all those fields, you may be able to compose the name of your artifacts
pretty much the way you want:

```yaml
example_template: '{{ tolower .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:

```sh
GOVERSION_NR=$(go version | awk '{print $3;}') goreleaser
```

!!! warning
    Note that those are hypothetical examples and the fields `foo_template` and
    `example_template` are not valid GoReleaser configurations.
