# Repositories API **(FREE)**
|
|
|
|
## List repository tree
|
|
|
|
Get a list of repository files and directories in a project. This endpoint can
|
|
be accessed without authentication if the repository is publicly accessible.
|
|
|
|
This command provides essentially the same functionality as the `git ls-tree` command. For more information, see the section _Tree Objects_ in the [Git internals documentation](https://git-scm.com/book/en/v2/Git-Internals-Git-Objects/#_tree_objects).
|
|
|
|
WARNING:
|
|
This endpoint is changing to keyset-based pagination. Iterating pages of results
|
|
with a number (`?page=2`) [is deprecated](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/67509).
|
|
Support for iterating with a number became supported in GitLab 15.0. Use
|
|
the new [keyset pagination system](index.md#keyset-based-pagination) instead.

## Add changelog data to a changelog file
|
|
|
|
> [Introduced](https://gitlab.com/groups/gitlab-com/gl-infra/-/epics/351) in GitLab 13.9.
|
|
|
|
Generate changelog data based on commits in a repository.
|
|
|
|
Given a version (using [semantic versioning](https://semver.org/)) and a range
|
|
of commits, GitLab generates a changelog for all commits that use a particular
|
|
[Git trailer](https://git-scm.com/docs/git-interpret-trailers).
|
|
|
|
The output of this process is a new section in a changelog file in the Git
|
|
repository of the given project. The output format is in Markdown, and can be
|
|
customized.
|
|
|
|
```plaintext
|
|
POST /projects/:id/repository/changelog
|
|
```
|
|
|
|
Supported attributes:
|
|
|
|
| Attribute | Type | Required | Description |
|
|
| :-------- | :------- | :--------- | :---------- |
|
|
| `version` | string | yes | The version to generate the changelog for. The format must follow [semantic versioning](https://semver.org/). |
|
|
| `from` | string | no | The start of the range of commits (as a SHA) to use for generating the changelog. This commit itself isn't included in the list. |
|
|
| `to` | string | no | The end of the range of commits (as a SHA) to use for the changelog. This commit _is_ included in the list. Defaults to the branch specified in the `branch` attribute. |
|
|
| `date` | datetime | no | The date and time of the release, defaults to the current time. |
|
|
| `branch` | string | no | The branch to commit the changelog changes to, defaults to the project's default branch. |
|
|
| `trailer` | string | no | The Git trailer to use for including commits, defaults to `Changelog`. |
|
|
| `config_file` | string | no | Path to the changelog configuration file in the project's Git repository. Defaults to `.gitlab/changelog_config.yml`. |
|
|
| `file` | string | no | The file to commit the changes to, defaults to `CHANGELOG.md`. |
|
|
| `message` | string | no | The commit message to produce when committing the changes, defaults to `Add changelog for version X` where X is the value of the `version` argument. |
|
|
|
|
WARNING:
|
|
GitLab treats trailers case-sensitively. If you set the `trailer` field to
|
|
`Example`, GitLab _won't_ include commits that use the trailer `example`,
|
|
`eXaMpLE`, or anything else that isn't _exactly_ `Example`.
|
|
|
|
WARNING:
|
|
The allowed commits range between `from` and `to` is limited to 15000 commits. To disable
|
|
this restriction, [turn off the feature flag](../administration/feature_flags.md)
|
|
`changelog_commits_limitation`.
|
|
|
|
If the `from` attribute is unspecified, GitLab uses the Git tag of the last
|
|
stable version that came before the version specified in the `version`
|
|
attribute. This requires that Git tag names follow a specific format, allowing
|
|
GitLab to extract a version from the tag names. By default, GitLab considers
|
|
tags using these formats:
|
|
|
|
- `vX.Y.Z`
|
|
- `X.Y.Z`
|
|
|
|
Where `X.Y.Z` is a version that follows [semantic versioning](https://semver.org/).
|
|
For example, consider a project with the following tags:
|
|
|
|
- v1.0.0-pre1
|
|
- v1.0.0
|
|
- v1.1.0
|
|
- v2.0.0
|
|
|
|
If the `version` attribute is `2.1.0`, GitLab uses tag v2.0.0. And when the
|
|
version is `1.1.1`, or `1.2.0`, GitLab uses tag v1.1.0. The tag `v1.0.0-pre1` is
|
|
never used, because pre-release tags are ignored.
|
|
|
|
If `from` is unspecified and no tag to use is found, the API produces an error.
|
|
To solve such an error, you must explicitly specify a value for the `from`
|
|
attribute.
|
|
|
|
### Examples
|
|
|
|
These examples use [cURL](https://curl.se/) to perform HTTP requests.
|
|
The example commands use these values:
|
|
|
|
- **Project ID**: 42
|
|
- **Location**: hosted on GitLab.com
|
|
- **Example API token**: `token`
|
|
|
|
This command generates a changelog for version `1.0.0`.
|
|
|
|
The commit range:
|
|
|
|
- Starts with the tag of the last release.
|
|
- Ends with the last commit on the target branch. The default target branch is the project's default branch.
|
|
|
|
If the last tag is `v0.9.0` and the default branch is `main`, the range of commits
|
|
included in this example is `v0.9.0..main`:
|
|
|
|
```shell
|
|
curl --request POST --header "PRIVATE-TOKEN: token" --data "version=1.0.0" "https://gitlab.com/api/v4/projects/42/repository/changelog"
|
|
```
|
|
|
|
To generate the data on a different branch, specify the `branch` parameter. This
|
|
command generates data from the `foo` branch:
|
|
|
|
```shell
|
|
curl --request POST --header "PRIVATE-TOKEN: token" --data "version=1.0.0&branch=foo" "https://gitlab.com/api/v4/projects/42/repository/changelog"
|
|
```
|
|
|
|
To use a different trailer, use the `trailer` parameter:
|
|
|
|
```shell
|
|
curl --request POST --header "PRIVATE-TOKEN: token" --data "version=1.0.0&trailer=Type" "https://gitlab.com/api/v4/projects/42/repository/changelog"
|
|
```
|
|
|
|
To store the results in a different file, use the `file` parameter:
|
|
|
|
```shell
|
|
curl --request POST --header "PRIVATE-TOKEN: token" --data "version=1.0.0&file=NEWS" "https://gitlab.com/api/v4/projects/42/repository/changelog"
|
|
```
|
|
|
|
### How it works
|
|
|
|
Changelogs are generated based on commit titles. Commits are only included if
|
|
they contain a specific Git trailer. GitLab uses the value of this trailer to
|
|
categorize the changes.
|
|
|
|
GitLab uses Git trailers, because Git trailers are
|
|
supported by Git out of the box. We use commits as input, as this is the only
|
|
source of data every project uses. In addition, commits can be retrieved when
|
|
operating on a mirror. This is important for GitLab itself, because during a security
|
|
release we might need to include changes from both public projects and private
|
|
security mirrors.
|
|
|
|
Changelogs are generated by taking the title of the commits to include and using
|
|
these as the changelog entries. You can enrich entries with additional data,
|
|
such as a link to the merge request or details about the commit author. You can
|
|
[customize the format of a changelog](#customize-the-changelog-output) section with a template.
|
|
|
|
Trailers can be manually added while editing a commit message. To include a commit
|
|
using the default trailer of `Changelog` and categorize it as a feature, the
|
|
trailer could be added to a commit message like so:
|
|
|
|
```plaintext
|
|
<Commit message subject>
|
|
|
|
<Commit message description>
|
|
|
|
Changelog: feature
|
|
```
|
|
|
|
### Reverted commits

> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/55537) in GitLab 13.10.
|
|
|
|
When generating a changelog for a range, GitLab ignores commits both added and
|
|
reverted in that range. Revert commits themselves _are_ included if they use the
|
|
Git trailer used for generating changelogs.
|
|
|
|
Imagine the following scenario: you have three commits: A, B, and C. To generate
|
|
changelogs, you use the default trailer `Changelog`. Both A and B use this
|
|
trailer. Commit C is a commit that reverts commit B. When generating a changelog
|
|
for this range, GitLab only includes commit A.
|
|
|
|
Revert commits are detected by looking for commits where the message contains
|
|
the pattern `This reverts commit SHA`, where `SHA` is the SHA of the commit that
|
|
is reverted.
|
|
|
|
If a revert commit includes the trailer used for generating changelogs
|
|
(`Changelog` in the above example), the revert commit itself _is_ included.
|
|
|
|
### Customize the changelog output
|
|
|
|
The output is customized using a YAML configuration file stored in your
|
|
project's Git repository. This default configuration file path is
|
|
`.gitlab/changelog_config.yml`.
|
|
|
|
You can set the following variables in this file:
|
|
|
|
- `date_format`: the date format to use in the title of the newly added
|
|
changelog data. This uses regular `strftime` formatting.
|
|
- `template`: a custom template to use for generating the changelog data.
|
|
- `categories`: a hash that maps raw category names to the names to use in the
|
|
changelog.
|
|
- `include_groups`: a list of group full paths containing users whose
|
|
contributions should be credited regardless of project membership. The user
|
|
generating the changelog must have access to each group or the members will
|
|
not be credited.
|
|
|
|
Using the default settings, generating a changelog results in a section along
|
|
the lines of the following:
|
|
|
|
```markdown
|
|
## 1.0.0 (2021-01-05)
|
|
|
|
### Features (4 changes)
|
|
|
|
- [Feature 1](gitlab-org/gitlab@123abc) by @alice ([merge request](gitlab-org/gitlab!123))
|
|
- [Feature 2](gitlab-org/gitlab@456abc) ([merge request](gitlab-org/gitlab!456))
|
|
- [Feature 3](gitlab-org/gitlab@234abc) by @steve
|
|
- [Feature 4](gitlab-org/gitlab@456)
|
|
```
|
|
|
|
Each section starts with a title that contains the version and release date.
|
|
While the format of the date can be customized, the rest of the title can't be
|
|
changed. When adding a new section, GitLab parses these titles to determine
|
|
where in the file the new section should be placed. GitLab sorts sections
|
|
according to their versions, not their dates.
|
|
|
|
Each section can have categories, each with their
|
|
corresponding changes. In the above example, "Features" is one such category.
|
|
You can customize the format of these sections.
|
|
|
|
The section names are derived from the values of the Git trailer used to include
|
|
or exclude commits.
|
|
|
|
For example, if the trailer to use is called `Changelog`,
|
|
and its value is `feature`, then the commit is grouped in the `feature`
|
|
category. The names of these raw values might differ from what you want to
|
|
show in a changelog, you can remap them. Let's say we use the `Changelog`
|
|
trailer and developers use the following values: `feature`, `bug`, and
|
|
`performance`.
|
|
|
|
You can remap these using the following YAML configuration file:
|
|
|
|
```yaml
|
|
---
|
|
categories:
|
|
feature: Features
|
|
bug: Bug fixes
|
|
performance: Performance improvements
|
|
```
|
|
|
|
When generating the changelog data, the category titles are then `### Features`,
|
|
`### Bug fixes`, and `### Performance improvements`.
|
|
|
|
### Custom templates
|
|
|
|
The category sections are generated using a template. The default template is as
|
|
follows:
|
|
|
|
```plaintext
|
|
{% if categories %}
|
|
{% each categories %}
|
|
### {{ title }} ({% if single_change %}1 change{% else %}{{ count }} changes{% end %})
|
|
|
|
{% each entries %}
|
|
- [{{ title }}]({{ commit.reference }})\
|
|
{% if author.credit %} by {{ author.reference }}{% end %}\
|
|
{% if merge_request %} ([merge request]({{ merge_request.reference }})){% end %}
|
|
|
|
{% end %}
|
|
|
|
{% end %}
|
|
{% else %}
|
|
No changes.
|
|
{% end %}
|
|
```
|
|
|
|
The `{% ... %}` tags are for statements, and `{{ ... }}` is used for printing
|
|
data. Statements must be terminated using a `{% end %}` tag. Both the `if` and
|
|
`each` statements require a single argument.
|
|
|
|
For example, if we have a variable `valid`, and we want to display "yes"
|
|
when this value is true, and display "nope" otherwise. We can do so as follows:
|
|
|
|
```plaintext
|
|
{% if valid %}
|
|
yes
|
|
{% else %}
|
|
nope
|
|
{% end %}
|
|
```
|
|
|
|
The use of `else` is optional. A value is considered true when it's a non-empty
|
|
value or boolean `true`. Empty arrays and hashes are considered false.
|
|
|
|
Looping is done using `each`, and variables inside a loop are scoped to it.
|
|
Referring to the current value in a loop is done using the variable tag `{{ it
|
|
}}`. Other variables read their value from the current loop value. Take
|
|
this template for example:
|
|
|
|
```plaintext
|
|
{% each users %}
|
|
{{name}}
|
|
{% end %}
|
|
```
|
|
|
|
Assuming `users` is an array of objects, each with a `name` field, this would
|
|
then print the name of every user.
|
|
|
|
Using variable tags, you can access nested objects. For example, `{{
|
|
users.0.name }}` prints the name of the first user in the `users` variable.
|
|
|
|
If a line ends in a backslash, the next newline is ignored. This allows you to
|
|
wrap code across multiple lines, without introducing unnecessary newlines in the
|
|
Markdown output.
|
|
|
|
Tags that use `{%` and `%}` (known as expression tags) consume the newline that
|
|
directly follows them, if any. This means that this:
|
|
|
|
```plaintext
|
|
---
|
|
{% if foo %}
|
|
bar
|
|
{% end %}
|
|
---
|
|
```
|
|
|
|
Compiles into this:
|
|
|
|
```plaintext
|
|
---
|
|
bar
|
|
---
|
|
```
|
|
|
|
Instead of this:
|
|
|
|
```plaintext
|
|
---
|
|
|
|
bar
|
|
|
|
---
|
|
```
|
|
|
|
You can specify a custom template in your configuration like so:
|
|
|
|
```yaml
|
|
---
|
|
template: |
|
|
{% if categories %}
|
|
{% each categories %}
|
|
### {{ title }}
|
|
|
|
{% each entries %}
|
|
- [{{ title }}]({{ commit.reference }})\
|
|
{% if author.credit %} by {{ author.reference }}{% end %}
|
|
|
|
{% end %}
|
|
|
|
{% end %}
|
|
{% else %}
|
|
No changes.
|
|
{% end %}
|
|
```
|
|
|
|
When specifying the template you should use `template: |` and not
|
|
`template: >`, as the latter doesn't preserve newlines in the template.
|
|
|
|
### Template data
|
|
|
|
At the top level, the following variable is available:
|
|
|
|
- `categories`: an array of objects, one for every changelog category.
|
|
|
|
In a category, the following variables are available:
|
|
|
|
- `title`: the title of the category (after it has been remapped).
|
|
- `count`: the number of entries in this category.
|
|
- `single_change`: a boolean that indicates if there is only one change (`true`),
|
|
or multiple changes (`false`).
|
|
- `entries`: the entries that belong to this category.
|
|
|
|
In an entry, the following variables are available (here `foo.bar` means that
|
|
`bar` is a sub-field of `foo`):
|
|
|
|
- `title`: the title of the changelog entry (this is the commit title).
|
|
- `commit.reference`: a reference to the commit, for example,
|
|
`gitlab-org/gitlab@0a4cdd86ab31748ba6dac0f69a8653f206e5cfc7`.
|
|
- `commit.trailers`: an object containing all the Git trailers that were present
|
|
in the commit body.
|
|
- `author.reference`: a reference to the commit author (for example, `@alice`).
|
|
- `author.contributor`: a boolean set to `true` when the author is not a project
|
|
member, otherwise `false`.
|
|
- `author.credit`: a boolean set to `true` when `author.contributor` is `true` or
|
|
when `include_groups` is configured, and the author is a member of one of the
|
|
groups.
|
|
- `merge_request.reference`: a reference to the merge request that first
|
|
introduced the change (for example, `gitlab-org/gitlab!50063`).
|
|
|
|
The `author` and `merge_request` objects might not be present if the data
|
|
couldn't be determined. For example, when a commit is created without a
|
|
corresponding merge request, no merge request is displayed.
|
|
|
|
### Customize the tag format when extracting versions
|
|
|
|
> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/56889) in GitLab 13.11.
|
|
|
|
GitLab uses a regular expression (using the
|
|
[re2](https://github.com/google/re2/) engine and syntax) to extract a semantic
|
|
version from tag names. The default regular expression is:
|
|
|
|
```plaintext
|
|
^v?(?P<major>0|[1-9]\d*)\.(?P<minor>0|[1-9]\d*)\.(?P<patch>0|[1-9]\d*)(?:-(?P<pre>(?:0|[1-9]\d*|\d*[a-zA-Z-][0-9a-zA-Z-]*)(?:\.(?:0|[1-9]\d*|\d*[a-zA-Z-][0-9a-zA-Z-]*))*))?(?:\+(?P<meta>[0-9a-zA-Z-]+(?:\.[0-9a-zA-Z-]+)*))?$
|
|
```
|
|
|
|
This regular expression is based on the official
|
|
[semantic versioning](https://semver.org/) regular expression, and also includes
|
|
support for tag names that start with the letter `v`.
|
|
|
|
If your project uses a different format for tags, you can specify a different
|
|
regular expression. The regular expression used _must_ produce the following
|
|
capture groups. If any of these capture groups are missing, the tag is ignored:
|
|
|
|
- `major`
|
|
- `minor`
|
|
- `patch`
|
|
|
|
The following capture groups are optional:
|
|
|
|
- `pre`: If set, the tag is ignored. Ignoring `pre` tags ensures release candidate
|
|
tags and other pre-release tags are not considered when determining the range of
|
|
commits to generate a changelog for.
|
|
- `meta`: Optional. Specifies build metadata.
|
|
|
|
Using this information, GitLab builds a map of Git tags and their release
|
|
versions. It then determines what the latest tag is, based on the version
|
|
extracted from each tag.
|
|
|
|
To specify a custom regular expression, use the `tag_regex` setting in your
|
|
changelog configuration YAML file. For example, this pattern matches tag names
|
|
such as `version-1.2.3` but not `version-1.2`.
|
|
|
|
```yaml
|
|
---
|
|
tag_regex: '^version-(?P<major>\d+)\.(?P<minor>\d+)\.(?P<patch>\d+)$'
|
|
```
|
|
|
|
To test if your regular expression is working, you can use websites such as
|
|
[regex101](https://regex101.com/). If the regular expression syntax is invalid,
|
|
an error is produced when generating a changelog.
|
|
|
|
## Generate changelog data
|
|
|
|
> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/345934) in GitLab 14.6.
|
|
|
|
Generate changelog data based on commits in a repository, without committing
|
|
them to a changelog file.
|
|
|
|
Works exactly like `POST /projects/:id/repository/changelog`, except the changelog
|
|
data isn't committed to any changelog file.
|
|
|
|
```plaintext
|
|
GET /projects/:id/repository/changelog
|
|
```
|
|
|
|

|
|
| `from` | string | no | The start of the range of commits (as a SHA) to use for generating the changelog. This commit itself isn't included in the list. |
|
|
| `to` | string | no | The end of the range of commits (as a SHA) to use for the changelog. This commit _is_ included in the list. Defaults to the branch specified in the `branch` attribute. |
|
|
| `date` | datetime | no | The date and time of the release, ISO 8601 formatted. Example: `2016-03-11T03:45:40Z`. Defaults to the current time. |

|
|
| `config_file` | string | no | The path of changelog configuration file in the project's Git repository, defaults to `.gitlab/changelog_config.yml`. |
|
|
|
|
```shell
|
|
curl --header "PRIVATE-TOKEN: token" "https://gitlab.com/api/v4/projects/42/repository/changelog?version=1.0.0"
