# Snippets
|
|
|
|
With GitLab Snippets you can store and share bits of code and text with other users.
|
|
|
|
![GitLab Snippet](img/gitlab_snippet_v13_0.png)
|
|
|
|
Snippets can be maintained using [snippets API](../api/snippets.md).
|
|
|
|
There are two types of snippets:
|
|
|
|
- Personal snippets.
|
|
- Project snippets.
|
|
|
|
## Personal snippets
|
|
|
|
Personal snippets are not related to any project and can be created completely
|
|
independently. There are 3 visibility levels that can be set, public, internal
|
|
and private. See [Public access](../public_access/public_access.md) for more information.
|
|
|
|
## Project snippets
|
|
|
|
Project snippets are always related to a specific project.
|
|
See [Project features](project/index.md#project-features) for more information.
|
|
|
|
## Create a snippet
|
|
|
|
To create a personal snippet, click the plus icon (**{plus-square-o}**)
|
|
on the top navigation and select **New snippet** from the dropdown menu:
|
|
|
|
![New personal snippet from non-project pages](img/new_personal_snippet_v12_10.png)
|
|
|
|
If you're on a project's page but you want to create a new personal snippet,
|
|
click the plus icon (**{plus-square-o}**) and select **New snippet** from the
|
|
lower part of the dropdown (**GitLab** on GitLab.com; **Your Instance** on
|
|
self-managed instances):
|
|
|
|
![New personal snippet from project pages](img/new_personal_snippet_from_project_v12_10.png)
|
|
|
|
To create a project snippet, navigate to your project's page and click the
|
|
plus icon (**{plus-square-o}**), then select **New snippet** from the upper
|
|
part of the dropdown (**This project**).
|
|
|
|
![New personal snippet from project pages](img/new_project_snippet_from_project_v12_10.png)
|
|
|
|
From there, add the **Title**, **Description**, and a **File** name with the
|
|
appropriate extension (for example, `example.rb`, `index.html`).
|
|
|
|
WARNING:
|
|
Make sure to add the file name to get code highlighting and to avoid this
|
|
[copy-pasting bug](https://gitlab.com/gitlab-org/gitlab/-/issues/22870).
|
|
|
|
## Versioned Snippets
|
|
|
|
> [Introduced](https://gitlab.com/groups/gitlab-org/-/epics/239) in GitLab 13.0.
|
|
|
|
Starting in 13.0, 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 `master` branch at the moment the snippet is created. Whenever a change to the snippet is saved, a
|
|
new commit to the master branch is recorded. Commit messages are automatically
|
|
generated. The snippet's repository has only one branch (master) by default, deleting
|
|
it or creating other branches is not supported.
|
|
|
|
Existing snippets will be automatically migrated in 13.0. Their current
|
|
content will be saved as the initial commit to the snippets' repository.
|
|
|
|
### File names
|
|
|
|
Snippets support syntax highlighting based on the filename and
|
|
extension provided for them. While it is possible to submit a snippet
|
|
without specifying a filename and extension, it needs a valid name so the
|
|
content can be created as a file in the snippet's repository.
|
|
|
|
In case the user does not attribute a filename and extension to a snippet,
|
|
GitLab automatically adds a filename in the format `snippetfile<x>.txt`
|
|
where `<x>` represents a number added to the file, starting with 1. This
|
|
number increases incrementally when more snippets without an attributed
|
|
filename are added.
|
|
|
|
When upgrading from an earlier version of GitLab to 13.0, existing snippets
|
|
without a supported filename will be renamed to a compatible format. For
|
|
example, if the snippet's filename is `http://a-weird-filename.me` it will
|
|
be changed to `http-a-weird-filename-me` to be included in the snippet's
|
|
repository. As snippets are stored by ID, changing their filenames will not break
|
|
direct or embedded links to the snippet.
|
|
|
|
### Multiple files by Snippet
|
|
|
|
> [Introduced](https://gitlab.com/groups/gitlab-org/-/epics/2829) in GitLab 13.5.
|
|
|
|
GitLab Snippets support multiple files in one single snippet. It can be very handy
|
|
when your code snippet is composed of multiple parts or when they relate
|
|
to a certain context. For example:
|
|
|
|
- A snippet that includes a script and its output.
|
|
- A snippet that includes HTML, CSS, and JS code.
|
|
- A snippet with a `docker-compose.yml` file and its associated `.env` file.
|
|
- A `gulpfile.js` file coupled with a `package.json` file, which together can be used to bootstrap a project and manage its dependencies.
|
|
|
|
Snippets support between 1 and 10 files. They can be managed via Git (since they're [versioned](#versioned-snippets)
|
|
by a Git repository), through the [Snippets API](../api/snippets.md), or within the GitLab UI.
|
|
|
|
![Multi-file Snippet](img/gitlab_snippet_v13_5.png)
|
|
|
|
To add a new file to your snippet through the GitLab UI:
|
|
|
|
1. Go to your snippet in the GitLab UI.
|
|
1. Click **Edit** in the top right.
|
|
1. Select **Add another file**.
|
|
1. Add your content to the file in the form fields provided.
|
|
1. Click **Save changes**.
|
|
|
|
To delete a file from your snippet through the GitLab UI:
|
|
|
|
1. Go to your snippet in the GitLab UI.
|
|
1. Click **Edit** in the top right.
|
|
1. Select **Delete file** alongside the file name of each file
|
|
you wish to delete.
|
|
1. Click **Save changes**.
|
|
|
|
### Cloning snippets
|
|
|
|
Snippets can be cloned as a regular Git repository using SSH or HTTPS. Click the **Clone**
|
|
button above the snippet content to copy the URL of your choice.
|
|
|
|
![Clone Snippet](img/snippet_clone_button_v13_0.png)
|
|
|
|
This allows you to have a local copy of the snippet's repository and make
|
|
changes as needed. You can commit those changes and push them to the remote
|
|
master branch.
|
|
|
|
### Reduce snippets repository size
|
|
|
|
Since 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).
|
|
|
|
### Limitations
|
|
|
|
- Binary files are not supported.
|
|
- Creating or deleting branches is not supported. Only a default *master* 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 will result in an error.
|
|
- Revisions are not *yet* visible to the user on the GitLab UI, but
|
|
it's planned to be added 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.
|
|
|
|
## Discover snippets
|
|
|
|
There are two main ways of how you can discover snippets in GitLab.
|
|
|
|
For exploring all snippets that are visible to you, you can go to the Snippets
|
|
dashboard of your GitLab instance via the top navigation. For GitLab.com you can
|
|
navigate to an [overview]((https://gitlab.com/dashboard/snippets)) that shows snippets
|
|
you created and allows you to explore all snippets.
|
|
|
|
If you want to discover snippets that belong to a specific project, you can navigate
|
|
to the Snippets page via the left side navigation on the project page.
|
|
Project snippets are enabled and available by default, but they can
|
|
be disabled by navigating to your project's **Settings**, expanding
|
|
**Visibility, project features, permissions** and scrolling down to
|
|
**Snippets**. From there, you can toggle to disable them or select a
|
|
different visibility level from the dropdown menu.
|
|
|
|
## Snippet comments
|
|
|
|
> [Introduced](https://gitlab.com/gitlab-org/gitlab-foss/-/issues/12910) in GitLab 9.2.
|
|
|
|
With GitLab Snippets you engage in a conversation about that piece of code,
|
|
facilitating the collaboration among users.
|
|
|
|
## Downloading snippets
|
|
|
|
You can download the raw content of a snippet.
|
|
|
|
By default snippets will be downloaded with Linux-style line endings (`LF`). If
|
|
you want to preserve the original line endings you need to add a parameter `line_ending=raw`
|
|
(e.g., `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`).
|
|
|
|
## Embedded snippets
|
|
|
|
> Introduced in GitLab 10.8.
|
|
|
|
Public snippets can not only be shared, but also embedded on any website. With
|
|
this, you can reuse a GitLab snippet in multiple places and any change to the source
|
|
is automatically reflected in the embedded snippet.
|
|
|
|
To embed a snippet, first make sure that:
|
|
|
|
- The project is public (if it's a project snippet)
|
|
- The snippet is public
|
|
- In **Project > Settings > Permissions**, the snippets permissions are
|
|
set to **Everyone with access**
|
|
|
|
Once the above conditions are met, the "Embed" section will appear in your
|
|
snippet where you can simply click on the "Copy" button. This copies a one-line
|
|
script that you can add to any website or blog post.
|
|
|
|
Here's how an example code looks like:
|
|
|
|
```html
|
|
<script src="https://gitlab.com/namespace/project/snippets/SNIPPET_ID.js"></script>
|
|
```
|
|
|
|
Here's how an embedded snippet looks like:
|
|
|
|
<script src="https://gitlab.com/gitlab-org/gitlab-foss/snippets/1717978.js"></script>
|
|
|
|
Embedded snippets are displayed with a header that shows the file name if it's defined,
|
|
the snippet size, a link to GitLab, and the actual snippet content. Actions in
|
|
the header allow users to see the snippet in raw format and download it.
|
