# Snippets **(FREE)**
|
|
|
|
With GitLab snippets, you can store and share bits of code and text with other users.
|
|
You can [comment on](#comment-on-snippets), [clone](#clone-snippets), and
|
|
[use version control](#versioned-snippets) in snippets. They can
|
|
[contain multiple files](#add-or-remove-multiple-files). They also support
|
|
[syntax highlighting](#filenames), [embedding](#embed-snippets), [downloading](#download-snippets),
|
|
and you can maintain your snippets with the [snippets API](../api/snippets.md).
|
|
|
|
|
|
|
|
GitLab provides two types of snippets:
|
|
|
|
- **Personal snippets**: Created independent of any project.
|
|
You can set a [visibility level](../public_access/public_access.md)
|
|
for your snippet: public, internal, or private.
|
|
- **Project snippets**: Always related to a specific project.
|
|
Project snippets can be visible publicly or to only group members.
|
|
|
|
## Create snippets
|
|
|
|
You can create snippets in multiple ways, depending on whether you want to create a personal or project snippet:
|
|
|
|
1. Select the kind of snippet you want to create:
|
|
- **To create a personal snippet**: On the
|
|
[Snippets dashboard](https://gitlab.com/dashboard/snippets), click
|
|
**New snippet**, or:
|
|
- *If you're on a project's page,* select the plus icon (**{plus-square-o}**)
|
|
in the top navigation bar, and then select **New snippet** from the
|
|
**GitLab** (GitLab SaaS) or **Your Instance** (self-managed) section
|
|
of the same dropdown menu.
|
|
- *For all other pages,* select the plus icon (**{plus-square-o}**)
|
|
in the top navigation bar, then select **New snippet** from the dropdown
|
|
menu.
|
|
- **To create a project snippet**: Go to your project's page. Select the
|
|
plus icon (**{plus-square-o}**), and then select **New snippet** from the
|
|
**This project** section of the dropdown menu.
|
|
1. Add a **Title** and **Description**.
|
|
1. Name your **File** with an appropriate extension, such as `example.rb` or `index.html`.
|
|
Filenames with appropriate extensions display [syntax highlighting](#filenames).
|
|
Failure to add a filename can cause a known
|
|
[copy-pasting bug](https://gitlab.com/gitlab-org/gitlab/-/issues/22870). If you don't provide a filename, GitLab [creates a name for you](#filenames).
|
|
1. (Optional) Add [multiple files](#add-or-remove-multiple-files) to your snippet.
|
|
1. Select a visibility level, and select **Create snippet**.
|
|
|
|
After you create a snippet, you can still [add more files to it](#add-or-remove-multiple-files).
|
|
In GitLab versions 13.0 and later, snippets are [versioned by default](#versioned-snippets).
|
|
|
|
## Discover snippets
|
|
|
|
To discover all snippets visible to you in GitLab, you can:
|
|
|
|
- **View all snippets visible to you**: On the top bar of your GitLab
|
|
instance, select **Menu > Snippets** to view your snippets dashboard.
|
|
- **Visit [GitLab snippets](https://gitlab.com/dashboard/snippets)** for your snippets on GitLab.com.
|
|
- **Explore all public snippets**: On the top bar of your GitLab
|
|
instance, select **Menu > Snippets** and select **Explore snippets** to view
|
|
[all public snippets](https://gitlab.com/explore/snippets).
|
|
- **View a project's snippets**: In your project,
|
|
go to **Snippets**.
|
|
|
|
## Change default visibility of snippets
|
|
|
|
Project snippets are enabled and available by default. To change their
|
|
default visibility:
|
|
|
|
1. In your project,
|
|
go to **Settings**.
|
|
1. Expand the **Visibility, project features, permissions** section, and scroll to **Snippets**.
|
|
1. Toggle the default visibility, and select whether snippets can be viewed by
|
|
everyone, or only project members.
|
|
1. Select **Save changes**.
|
|
|
|
## Versioned snippets
|
|
|
|
> [Introduced](https://gitlab.com/groups/gitlab-org/-/epics/239) in GitLab 13.0.
|
|
|
|
In GitLab versions 13.0 and later, snippets (both personal and project snippets)
|
|
have version control enabled by default.
|
|
|
|
This means that all snippets get their own underlying repository initialized with
|
|
a default branch at the moment the snippet is created. Whenever a change to the snippet is saved, a
|
|
new commit to the default branch is recorded. Commit messages are automatically
|
|
generated. The snippet's repository has only one branch. You can't delete this branch,
|
|
or create other branches.
|
|
|
|
Existing snippets were automatically migrated in 13.0. Their current
|
|
content was saved as the initial commit to the snippets' repository.
|
|
|
|
## Filenames
|
|
|
|
Snippets support syntax highlighting based on the filename and
|
|
extension provided for them. While you can submit a snippet
|
|
without a filename and extension, it needs a valid name so the
|
|
content can be created as a file in the snippet's repository.
|
|
|
|
If you don't give a snippet a filename and extension,
|
|
GitLab adds a filename in the format `snippetfile<x>.txt`
|
|
where `<x>` represents a number added to the file, starting with 1. This
|
|
number increments if you add more unnamed snippets.
|
|
|
|
When upgrading from an earlier version of GitLab to 13.0, existing snippets
|
|
without a supported filename are renamed to a compatible format. For
|
|
example, if the snippet's filename is `http://a-weird-filename.me` it is
|
|
changed to `http-a-weird-filename-me` to be included in the snippet's
|
|
repository. As snippets are stored by ID, changing their filenames breaks
|
|
direct or embedded links to the snippet.
|
|
|
|
## Add or remove multiple files
|
|
|
|
> [Introduced](https://gitlab.com/groups/gitlab-org/-/epics/2829) in GitLab 13.5.
|
|
|
|
A single snippet can support up to 10 files, which helps keep related files together, such as:
|
|
|
|
- A snippet that includes a script and its output.
|
|
- A snippet that includes HTML, CSS, and JavaScript code.
|
|
- A snippet with a `docker-compose.yml` file and its associated `.env` file.
|
|
- A `gulpfile.js` file and a `package.json` file, which together can be
|
|
used to bootstrap a project and manage its dependencies.
|
|
|
|
If you need more than 10 files for your snippet, we recommend you create a
|
|
[wiki](project/wiki/index.md) instead. Wikis are available for projects at all
|
|
subscription levels, and [groups](project/wiki/index.md#group-wikis) for
|
|
[GitLab Premium](https://about.gitlab.com/pricing).
|
|
|
|
Snippets with multiple files display a file count in the [snippet list](http://snippets.gitlab.com/):
|
|
|
|
|
|
|
|
You can manage snippets with Git (because they're [versioned](#versioned-snippets)
|
|
by a Git repository), through the [Snippets API](../api/snippets.md), and in the GitLab UI.
|
|
|
|
To add a new file to your snippet through the GitLab UI:
|
|
|
|
1. Go to your snippet in the GitLab UI.
|
|
1. Select **Edit** in the top right corner.
|
|
1. Select **Add another file**.
|
|
1. Add your content to the file in the form fields provided.
|
|
1. Select **Save changes**.
|
|
|
|
To delete a file from your snippet through the GitLab UI:
|
|
|
|
1. Go to your snippet in the GitLab UI.
|
|
1. Select **Edit** in the top right corner.
|
|
1. Select **Delete file** alongside the filename of each file
|
|
you wish to delete.
|
|
1. Select **Save changes**.
|
|
|
|
## Clone snippets
|
|
|
|
Instead of copying a snippet to a local file, you may want to clone a snippet to
|
|
preserve its relationship with the repository, so you can receive or make updates
|
|
as needed. Select the **Clone** button on a snippet to display the URLs to clone with SSH or HTTPS:
|
|
|
|
|
|
|
|
You can commit changes to a cloned snippet, and push the changes to GitLab.
|
|
|
|
## Embed snippets
|
|
|
|
Public snippets can be shared and embedded on any website. You can reuse a GitLab snippet in multiple places, and any change to the source
|
|
is reflected in the embedded snippets. When embedded, users can download it, or view the snippet in raw format.
|
|
|
|
To embed a snippet:
|
|
|
|
1. Confirm your snippet is publicly visible:
|
|
- *If it's a project snippet*, the project must be public.
|
|
- The snippet is publicly visible.
|
|
- In **Project > Settings > Permissions**, the snippets
|
|
permissions are set to **Everyone with access**.
|
|
1. In your snippet's **Embed** section, select **Copy** to copy a one-line script you can add to any website or blog post. For example:
|
|
|
|
```html
|
|
<script src="https://gitlab.com/namespace/project/snippets/SNIPPET_ID.js"></script>
|
|
```
|
|
|
|
1. Add your script to your file.
|
|
|
|
Embedded snippets display a header that shows:
|
|
|
|
- The filename, if defined.
|
|
- The snippet size.
|
|
- A link to GitLab.
|
|
- The actual snippet content.
|
|
|
|
For example:
|
|
|
|
<script src="https://gitlab.com/gitlab-org/gitlab-foss/snippets/1717978.js"></script>
|
|
|
|
## Download snippets
|
|
|
|
You can download the raw content of a snippet. By default, they download with Linux-style line endings (`LF`). If
|
|
you want to preserve the original line endings you need to add a parameter `line_ending=raw`
|
|
(For example: `https://gitlab.com/snippets/SNIPPET_ID/raw?line_ending=raw`). In case a
|
|
snippet was created using the GitLab web interface the original line ending is Windows-like (`CRLF`).
|
|
|
|
## Comment on snippets
|
|
|
|
With snippets, you engage in a conversation about that piece of code,
|
|
which can encourage user collaboration.
|
|
|
|
## Troubleshooting
|
|
|
|
### Snippet limitations
|
|
|
|
- Binary files are not supported.
|
|
- Creating or deleting branches is not supported. Only the default branch is used.
|
|
- Git tags are not supported in snippet repositories.
|
|
- Snippets' repositories are limited to 10 files. Attempting to push more
|
|
than 10 files results in an error.
|
|
- Revisions are not visible to the user on the GitLab UI, but this feature is planned
|
|
in future iterations. See the [revisions tab issue](https://gitlab.com/gitlab-org/gitlab/-/issues/39271)
|
|
for updates.
|
|
- The [maximum size for a snippet](../administration/snippets/index.md#snippets-content-size-limit)
|
|
is 50 MB, by default.
|
|
- Git LFS is not supported.
|
|
|
|
### Reduce snippets repository size
|
|
|
|
Because versioned snippets are considered as part of the [namespace storage size](../user/admin_area/settings/account_and_limit_settings.md),
|
|
it's recommended to keep snippets' repositories as compact as possible.
|
|
|
|
For more information about tools to compact repositories,
|
|
see the documentation on [reducing repository size](../user/project/repository/reducing_the_repo_size_using_git.md).
