# GitLab Flavored Markdown (GLFM) **(FREE)**
|
|
|
|
> The abbreviation [changed](https://gitlab.com/gitlab-org/gitlab/-/issues/24592) from `GFM` to `GLFM` in GitLab 14.10.
|
|
|
|
When you enter text in the GitLab UI, GitLab assumes the text is in the Markdown language.
|
|
The text is rendered with a set of styles. These styles are called *GitLab Flavored Markdown*.
|
|
|
|
For example, in Markdown, an unordered list looks like this:
|
|
|
|
```markdown
|
|
- Cat
|
|
- Dog
|
|
- Turtle
|
|
```
|
|
|
|
When this list is rendered, it looks like this:
|
|
|
|
- Cat
|
|
- Dog
|
|
- Turtle
|
|
|
|
These styles are **valid for GitLab only**. The [GitLab documentation website](https://docs.gitlab.com)
|
|
and the [main GitLab website](https://about.gitlab.com) use [Kramdown](https://kramdown.gettalong.org) instead.
|
|
|
|
You should not view this page in the documentation, but instead [view these styles as they appear on GitLab](https://gitlab.com/gitlab-org/gitlab/-/blob/master/doc/user/markdown.md).
|
|
|
|
GitLab Flavored Markdown extends the [CommonMark specification](https://spec.commonmark.org/current/).
|
|
It was inspired by [GitHub Flavored Markdown](https://docs.github.com/en/get-started/writing-on-github/getting-started-with-writing-and-formatting-on-github/basic-writing-and-formatting-syntax).
|
|
|
|
## Where you can use GitLab Flavored Markdown
|
|
|
|
You can use GitLab Flavored Markdown in the following areas:
|
|
|
|
- Comments
|
|
- Issues
|
|
- Merge requests
|
|
- Milestones
|
|
- Snippets (the snippet must be named with a `.md` extension)
|
|
- Wiki pages
|
|
- Markdown documents inside repositories
|
|
- Epics
|
|
|
|
You can also use other rich text files in GitLab. You might have to install a dependency
|
|
to do so. For more information, see the [`gitlab-markup` gem project](https://gitlab.com/gitlab-org/gitlab-markup).
|
|
|
|
### Differences between GitLab Flavored Markdown and standard Markdown

## Features not found in standard Markdown
|
|
|
|
The following features are not found in standard Markdown.
|
|
|
|
### Colors
|
|
|
|
[View this topic in GitLab](https://gitlab.com/gitlab-org/gitlab/-/blob/master/doc/user/markdown.md#colors).
|
|
|
|
You can write a color in the formats: `HEX`, `RGB`, or `HSL`.
|
|
|
|
- `HEX`: `` `#RGB[A]` `` or `` `#RRGGBB[AA]` ``
|
|
- `RGB`: `` `RGB[A](R, G, B[, A])` ``
|
|
- `HSL`: `` `HSL[A](H, S, L[, A])` ``
|
|
|
|
Named colors are not supported.
|
|
|
|
Colors in backticks are followed by a color indicator:
|
|
|
|
```markdown
|
|
- `#F00`
|
|
- `#F00A`
|
|
- `#FF0000`
|
|
- `#FF0000AA`
|
|
- `RGB(0,255,0)`
|
|
- `RGB(0%,100%,0%)`
|
|
- `RGBA(0,255,0,0.3)`
|
|
- `HSL(540,70%,50%)`
|
|
- `HSLA(540,70%,50%,0.3)`
|
|
```
|
|
|
|
- `#F00`
|
|
- `#F00A`
|
|
- `#FF0000`
|
|
- `#FF0000AA`
|
|
- `RGB(0,255,0)`
|
|
- `RGB(0%,100%,0%)`
|
|
- `RGBA(0,255,0,0.3)`
|
|
- `HSL(540,70%,50%)`
|
|
- `HSLA(540,70%,50%,0.3)`
|
|
|
|
### Diagrams and flowcharts
|
|
|
|
You can generate diagrams and flowcharts from text by using [Mermaid](https://mermaidjs.github.io/) or [PlantUML](https://plantuml.com).
|
|
You can also use [Kroki](https://kroki.io) to create a wide variety of diagrams.
|
|
|
|
#### Mermaid
|
|
|
|
Visit the [official page](https://mermaidjs.github.io/) for more details. The
|
|
[Mermaid Live Editor](https://mermaid-js.github.io/mermaid-live-editor/) helps you
|
|
learn Mermaid and debug issues in your Mermaid code. Use it to identify and resolve
|
|
issues in your diagrams.
|
|
|
|
To generate a diagram or flowchart, write your text inside the `mermaid` block:
|
|
|
|
````markdown
|
|
```mermaid
|
|
graph TD;
|
|
A-->B;
|
|
A-->C;
|
|
B-->D;
|
|
C-->D;
|
|
```
|
|
````
|
|
|
|
```mermaid
|
|
graph TD;
|
|
A-->B;
|
|
A-->C;
|
|
B-->D;
|
|
C-->D;
|
|
```
|
|
|
|
You can also include subgraphs:
|
|
|
|
````markdown
|
|
```mermaid
|
|
graph TB
|
|
|
|
SubGraph1 --> SubGraph1Flow
|
|
subgraph "SubGraph 1 Flow"
|
|
SubGraph1Flow(SubNode 1)
|
|
SubGraph1Flow -- Choice1 --> DoChoice1
|
|
SubGraph1Flow -- Choice2 --> DoChoice2
|
|
end
|
|
|
|
subgraph "Main Graph"
|
|
Node1[Node 1] --> Node2[Node 2]
|
|
Node2 --> SubGraph1[Jump to SubGraph1]
|
|
SubGraph1 --> FinalThing[Final Thing]
|
|
end
|
|
```
|
|
````
|
|
|
|
```mermaid
|
|
graph TB
|
|
|
|
SubGraph1 --> SubGraph1Flow
|
|
subgraph "SubGraph 1 Flow"
|
|
SubGraph1Flow(SubNode 1)
|
|
SubGraph1Flow -- Choice1 --> DoChoice1
|
|
SubGraph1Flow -- Choice2 --> DoChoice2
|
|
end
|
|
|
|
subgraph "Main Graph"
|
|
Node1[Node 1] --> Node2[Node 2]
|
|
Node2 --> SubGraph1[Jump to SubGraph1]
|
|
SubGraph1 --> FinalThing[Final Thing]
|
|
end
|
|
```
|
|
|
|
#### PlantUML
|
|
|
|
PlantUML integration is enabled on GitLab.com. To make PlantUML available in self-managed
|
|
installation of GitLab, a GitLab administrator [must enable it](../administration/integration/plantuml.md).
|
|
|
|
#### Kroki
|
|
|
|
To make Kroki available in GitLab, a GitLab administrator must enable it.
|
|
For more information, see the [Kroki integration](../administration/integration/kroki.md) page.

|
|
|
#### Emojis and your operating system
|
|
|
|
The previous emoji example uses hard-coded images. Rendered emojis
|
|
in GitLab may be different depending on the OS and browser used.
|
|
|
|
Most emojis are natively supported on macOS, Windows, iOS, Android, and fall back on image-based
|
|
emojis where there is no support.
|
|
|
|
<!-- vale gitlab.Spelling = NO -->
|
|
|
|
On Linux, you can download [Noto Color Emoji](https://github.com/googlefonts/noto-emoji)
|
|
to get full native emoji support. Ubuntu 18.04 (like many modern Linux distributions) has
|
|
this font installed by default.
|
|
|
|
<!-- vale gitlab.Spelling = YES -->
|
|
|
|
### Front matter
|
|
|
|
Front matter is metadata included at the beginning of a Markdown document, preceding
|
|
the content. This data can be used by static site generators like [Jekyll](https://jekyllrb.com/docs/front-matter/),
|
|
[Hugo](https://gohugo.io/content-management/front-matter/), and many other applications.
|
|
|
|
When you view a Markdown file rendered by GitLab, front matter is displayed as-is,
|
|
in a box at the top of the document. The HTML content displays after the front matter. To view an example,
|
|
you can toggle between the source and rendered version of a
|
|
[GitLab documentation file](https://gitlab.com/gitlab-org/gitlab/-/blob/master/doc/index.md).
|
|
|
|
In GitLab, front matter is used only in Markdown files and wiki pages, not the other
|
|
places where Markdown formatting is supported. It must be at the very top of the document
|
|
and must be between delimiters.
|
|
|
|
The following delimiters are supported:
|
|
|
|
- YAML (`---`):
|
|
|
|
```yaml
|
|
---
|
|
title: About Front Matter
|
|
example:
|
|
language: yaml
|
|
---
|
|
```
|
|
|
|
- TOML (`+++`):
|
|
|
|
```toml
|
|
+++
|
|
title = "About Front Matter"
|
|
[example]
|
|
language = "toml"
|
|
+++
|
|
```
|
|
|
|
- JSON (`;;;`):
|
|
|
|
```json
|
|
;;;
|
|
{
|
|
"title": "About Front Matter"
|
|
"example": {
|
|
"language": "json"
|
|
}
|
|
}
|
|
;;;
|
|
```
|
|
|
|
Other languages are supported by adding a specifier to any of the existing
|
|
delimiters. For example:
|
|
|
|
```php
|
|
---php
|
|
$title = "About Front Matter";
|
|
$example = array(
|
|
'language' => "php",
|
|
);
|
|
---
|
|
```
|
|
|
|
### Inline diff
|
|
|
|
[View this topic in GitLab](https://gitlab.com/gitlab-org/gitlab/-/blob/master/doc/user/markdown.md#inline-diff).
|
|
|
|
With inline diff tags, you can display `{+ additions +}` or `[- deletions -]`.
|
|
|
|
The wrapping tags can be either curly braces or square brackets:
|
|
|
|
```markdown
|
|
- {+ addition 1 +}
|
|
- [+ addition 2 +]
|
|
- {- deletion 3 -}
|
|
- [- deletion 4 -]
|
|
```
|
|
|
|
|
|
|
|
---
|
|
|
|
However, you cannot mix the wrapping tags:
|
|
|
|
```markdown
|
|
- {+ addition +]
|
|
- [+ addition +}
|
|
- {- deletion -]
|
|
- [- deletion -}
|
|
```
|
|
|
|
If your diff includes words in `` `code` `` font, make sure to escape each backtick `` ` `` with a
|
|
backslash `\`. Otherwise the diff highlight does not render correctly:
|
|
|
|
```markdown
|
|
- {+ Just regular text +}
|
|
- {+ Text with `backticks` inside +}
|
|
- {+ Text with escaped \`backticks\` inside +}
|
|
```
|
|
|
|
|
|
|
|
### Math
|
|
|
|
[View this topic in GitLab](https://gitlab.com/gitlab-org/gitlab/-/blob/master/doc/user/markdown.md#math).
|
|
|
|
Math written in LaTeX syntax is rendered with [KaTeX](https://github.com/KaTeX/KaTeX).
|
|
_KaTeX only supports a [subset](https://katex.org/docs/supported.html) of LaTeX._
|
|
This syntax also works for the Asciidoctor `:stem: latexmath`. For details, see
|
|
the [Asciidoctor user manual](https://asciidoctor.org/docs/user-manual/#activating-stem-support).
|
|
|
|
Math written between dollar signs with backticks (``$`...`$``) is rendered
|
|
inline with the text. Math written in a [code block](#code-spans-and-blocks) with
|
|
the language declared as `math` is rendered on a separate line:
|
|
|
|
````markdown
|
|
This math is inline: $`a^2+b^2=c^2`$.
|
|
|
|
This math is on a separate line:
|
|
|
|
```math
|
|
a^2+b^2=c^2
|
|
```
|
|
````
|
|
|
|
This math is inline: $`a^2+b^2=c^2`$.
|
|
|
|
This math is on a separate line:
|
|
|
|
```math
|
|
a^2+b^2=c^2
|
|
```
|
|
|
|
#### LaTeX-compatible fencing
|
|
|
|
> Introduced in GitLab 15.4 [with a flag](../administration/feature_flags.md) named `markdown_dollar_math`. Disabled by default.
|
|
|
|
[View this topic in GitLab](https://gitlab.com/gitlab-org/gitlab/-/blob/master/doc/user/markdown.md#latex-compatible-fencing).
|
|
|
|
FLAG:
|
|
On self-managed GitLab, by default this feature is not available. To make it available,
|
|
ask an administrator to [enable the feature flag](../administration/feature_flags.md) named `markdown_dollar_math`.
|
|
On GitLab.com, this feature is available.
|
|
The feature is not ready for production use.
|
|
|
|
Math written between dollar signs (`$...$`) is rendered
|
|
inline with the text. Math written between double dollar signs (`$$...$$`) is rendered
|
|
on a separate line:
|
|
|
|
````markdown
|
|
This math is inline: $a^2+b^2=c^2$.
|
|
|
|
This math is on a separate line: $$a^2+b^2=c^2$$
|
|
|
|
This math is on a separate line:
|
|
|
|
$$
|
|
a^2+b^2=c^2
|
|
$$
|
|
````
|
|
|
|
<!-- Uncomment the example below when the flag is enabled on GitLab.com -->
|
|
<!-- This math is inline: $a^2+b^2=c^2$.
|
|
|
|
This math is on a separate line: $$a^2+b^2=c^2$$
|
|
|
|
This math is on a separate line:
|
|
|
|
$$
|
|
a^2+b^2=c^2
|
|
$$ -->
|
|
|
|
### Task lists
|
|
|
|
> Inapplicable checkboxes [introduced](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/85982) in GitLab 15.3.
|
|
|
|
[View this topic in GitLab](https://gitlab.com/gitlab-org/gitlab/-/blob/master/doc/user/markdown.md#task-lists).
|
|
|
|
You can add task lists anywhere Markdown is supported.
|
|
|
|
- In issues, merge requests, and comments, you can select the boxes.
|
|
- In all other places, you cannot select the boxes. You must edit the Markdown manually
|
|
by adding or removing an `x` in the brackets.
|
|
|
|
Besides complete and incomplete, tasks can also be **inapplicable**. Selecting an inapplicable checkbox
|
|
in an issue, merge request, or comment has no effect.
|
|
|
|
To create a task list, follow the format of an ordered or unordered list:
|
|
|
|
```markdown
|
|
- [x] Completed task
|
|
- [~] Inapplicable task
|
|
- [ ] Incomplete task
|
|
- [x] Sub-task 1
|
|
- [~] Sub-task 2
|
|
- [ ] Sub-task 3
|
|
|
|
1. [x] Completed task
|
|
1. [~] Inapplicable task
|
|
1. [ ] Incomplete task
|
|
1. [x] Sub-task 1
|
|
1. [~] Sub-task 2
|
|
1. [ ] Sub-task 3
|
|
```
|
|
|
|
|
|
|
|
### Table of contents
|
|
|
|
A table of contents is an unordered list that links to subheadings in the document.
|
|
You can add a table of contents to issues and merge requests, but you can't add one
|
|
to notes or comments. Add either the `[[_TOC_]]` or `[TOC]` tag on its own line
|
|
to the **Description** field of any of the supported content types:
|
|
|
|
- Markdown files.
|
|
- Wiki pages.
|
|
- Issues.
|
|
- Merge requests.
|
|
|
|
```markdown
|
|
This sentence introduces my wiki page.
|
|
|
|
[[_TOC_]]
|
|
|
|
## My first heading
|
|
|
|
First section content.
|
|
|
|
## My second heading
|
|
|
|
Second section content.
|
|
```
|
|
|
|
|
|
|
|
### Wiki-specific Markdown
|
|
|
|
The following topics show how links inside wikis behave.
|
|
|
|
#### Wiki - direct page link
|
|
|
|
A direct page link includes the slug for a page that points to that page,
|
|
at the base level of the wiki.
|
|
|
|
This example links to a `documentation` page at the root of your wiki:
|
|
|
|
```markdown
|
|
[Link to Documentation](documentation)
|
|
```
|
|
|
|
#### Wiki - direct file link
|
|
|
|
A direct file link points to a file extension for a file, relative to the current page.
|
|
|
|
If the following example is on a page at `<your_wiki>/documentation/related`,
|
|
it links to `<your_wiki>/documentation/file.md`:
|
|
|
|
```markdown
|
|
[Link to File](file.md)
|
|
```
|
|
|
|
#### Wiki - hierarchical link
|
|
|
|
A hierarchical link can be constructed relative to the current wiki page by using `./<page>`,
|
|
`../<page>`, and so on.
|
|
|
|
If this example is on a page at `<your_wiki>/documentation/main`,
|
|
it links to `<your_wiki>/documentation/related`:
|
|
|
|
```markdown
|
|
[Link to Related Page](related)
|
|
```
|
|
|
|
If this example is on a page at `<your_wiki>/documentation/related/content`,
|
|
it links to `<your_wiki>/documentation/main`:
|
|
|
|
```markdown
|
|
[Link to Related Page](../main)
|
|
```
|
|
|
|
If this example is on a page at `<your_wiki>/documentation/main`,
|
|
it links to `<your_wiki>/documentation/related.md`:
|
|
|
|
```markdown
|
|
[Link to Related Page](related.md)
|
|
```
|
|
|
|
If this example is on a page at `<your_wiki>/documentation/related/content`,
|
|
it links to `<your_wiki>/documentation/main.md`:
|
|
|
|
```markdown
|
|
[Link to Related Page](../main.md)
|
|
```
|
|
|
|
#### Wiki - root link
|
|
|
|
A root link starts with a `/` and is relative to the wiki root.
|
|
|
|
This example links to `<wiki_root>/documentation`:
|
|
|
|
```markdown
|
|
[Link to Related Page](/documentation)
|
|
```
|
|
|
|
This example links to `<wiki_root>/miscellaneous.md`:
|
|
|
|
```markdown
|
|
[Link to Related Page](/miscellaneous.md)
|
|
```
|
|
|
|
## GitLab-specific references
|
|
|
|
GitLab Flavored Markdown renders GitLab-specific references. For example, you can reference
|
|
an issue, a commit, a team member, or even an entire project team. GitLab Flavored Markdown turns
|
|
that reference into a link so you can navigate between them. All references to projects should use the
|
|
**project slug** rather than the project name.
|
|
|
|
Additionally, GitLab Flavored Markdown recognizes certain cross-project references and also has a shorthand
|
|
version to reference other projects from the same namespace.
|
|
|
|
GitLab Flavored Markdown recognizes the following:
|
|
|
|
| references | input | cross-project reference | shortcut inside same namespace |
|
|
|:----------------------------------------------------------------------------|:------------------------------|:----------------------------------------|:-------------------------------|
|
|
| specific user | `@user_name` | | |
|
|
| specific group | `@group_name` | | |
|
|
| entire team | `@all` | | |
|
|
| project | `namespace/project>` | | |
|
|
| issue | ``#123`` | `namespace/project#123` | `project#123` |
|
|
| merge request | `!123` | `namespace/project!123` | `project!123` |
|
|

|
|
| feature flag | `[feature_flag:123]` | `[feature_flag:namespace/project/123]` | `[feature_flag:project/123]` |
|
|
| label by ID | `~123` | `namespace/project~123` | `project~123` |
|
|
| one-word label by name | `~bug` | `namespace/project~bug` | `project~bug` |
|
|
| multi-word label by name | `~"feature request"` | `namespace/project~"feature request"` | `project~"feature request"` |
|
|
| scoped label by name | `~"priority::high"` | `namespace/project~"priority::high"` | `project~"priority::high"` |
|
|
| project milestone by ID | `%123` | `namespace/project%123` | `project%123` |

|
|
|
|
1. [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/222483) in GitLab 13.7.
|
|
|
|
For example, referencing an issue by using `#123` formats the output as a link
|
|
to issue number 123 with text `#123`. Likewise, a link to issue number 123 is
|
|
recognized and formatted with text `#123`. If you don't want `#123` to link to an issue,
|
|
add a leading backslash `\#123`.
|
|
|
|
In addition to this, links to some objects are also recognized and formatted. Some examples of these are:
|
|
|
|
- Comments on issues: `"https://gitlab.com/gitlab-org/gitlab/-/issues/1234#note_101075757"`, which are rendered as `#1234 (comment 101075757)`
|
|
- The issues designs tab: `"https://gitlab.com/gitlab-org/gitlab/-/issues/1234/designs"`, which are rendered as `#1234 (designs)`.
|
|
- Links to individual designs: `"https://gitlab.com/gitlab-org/gitlab/-/issues/1234/designs/layout.png"`, which are rendered as `#1234[layout.png]`.
|
|
|
|
### Show the issue, merge request, or epic title in the reference
|
|
|
|
> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/15694) in GitLab 14.6.
|
|
|
|
To include the title in the rendered link of an issue, merge request, or epic, add a plus (`+`)
|
|
at the end of the reference. For example, a reference like `#123+` is rendered as
|
|
`The issue title (#123)`.
|
|
|
|
URL references like `https://gitlab.com/gitlab-org/gitlab/-/issues/1234+` are also expanded.
|
|
|
|
### Embedding metrics in GitLab Flavored Markdown
|
|
|
|
Metric charts can be embedded in GitLab Flavored Markdown. Read
|
|
[Embedding Metrics in GitLab flavored Markdown](../operations/metrics/embed.md) for more details.
|
|
|
|
## Features extended from standard Markdown
|
|
|
|
All standard Markdown formatting should work as expected in GitLab. Some standard
|
|
functionality is extended with additional features, without affecting the standard usage.
|
|
If a functionality is extended, the new option is listed as a sub-section.
|
|
|
|
### Blockquotes
|
|
|
|
Use a blockquote to highlight information, such as a side note. It's generated
|
|
by starting the lines of the blockquote with `>`:
|
|
|
|
```markdown
|
|
> Blockquotes help you emulate reply text.
|
|
> This line is part of the same quote.
|
|
|
|
Quote break.
|
|
|
|
> This very long line is still quoted properly when it wraps. Keep writing to make sure this line is long enough to actually wrap for everyone. You can also *add* **Markdown** into a blockquote.
|
|
```
|
|
|
|
> Blockquotes help you emulate reply text.
|
|
> This line is part of the same quote.
|
|
|
|
Quote break.
|
|
|
|
> This very long line is still quoted properly when it wraps. Keep writing to make sure this line is long enough to actually wrap for everyone. You can also *add* **Markdown** into a blockquote.
|
|
|
|
#### Multiline blockquote
|
|
|
|
If this section isn't rendered correctly, [view it in GitLab](https://gitlab.com/gitlab-org/gitlab/-/blob/master/doc/user/markdown.md#multiline-blockquote).
|
|
|
|
GitLab Flavored Markdown extends the standard Markdown by also supporting multi-line blockquotes
|
|
fenced by `>>>`, with a blank line before and after the block:
|
|
|
|
```markdown
|
|
|
|
>>>
|
|
If you paste a message from somewhere else
|
|
|
|
that spans multiple lines,
|
|
|
|
you can quote that without having to manually prepend `>` to every line!
|
|
>>>
|
|
|
|
```
|
|
|
|
>>>
|
|
If you paste a message from somewhere else
|
|
|
|
that spans multiple lines,
|
|
|
|
you can quote that without having to manually prepend `>` to every line!
|
|
>>>
|
|
|
|
### Code spans and blocks
|
|
|
|
You can highlight anything that should be viewed as code and not standard text.
|
|
|
|
Inline code is highlighted with single backticks `` ` ``:
|
|
|
|
```markdown
|
|
Inline `code` has `back-ticks around` it.
|
|
```
|
|
|
|
Inline `code` has `back-ticks around` it.
|
|
|
|
---
|
|
|
|
To achieve a similar effect for a larger code example, you can:
|
|
|
|
- Fence an entire block of code with triple backticks (```` ``` ````).
|
|
- Fence an entire block of code with triple tildes (`~~~`).
|
|
- Indent it four or more spaces.
|
|
|
|
````markdown
|
|
```python
|
|
def function():
|
|
#indenting works just fine in the fenced code block
|
|
s = "Python code"
|
|
print s
|
|
```
|
|
|
|
Using 4 spaces
|
|
is like using
|
|
3-backtick fences.
|
|
````
|
|
|
|
```plaintext
|
|
~~~
|
|
Tildes are OK too.
|
|
~~~
|
|
```
|
|
|
|
The three examples above render as:
|
|
|
|
```python
|
|
def function():
|
|
#indenting works just fine in the fenced code block
|
|
s = "Python code"
|
|
print s
|
|
```
|
|
|
|
```plaintext
|
|
Using 4 spaces

|
|
```

|
|

|
|
```
|
|
|
|
#### Colored code and syntax highlighting
|
|
|
|
If this section isn't rendered correctly,
|
|
[view it in GitLab](https://gitlab.com/gitlab-org/gitlab/-/blob/master/doc/user/markdown.md#colored-code-and-syntax-highlighting).
|
|
|
|
GitLab uses the [Rouge Ruby library](http://rouge.jneen.net/) for more colorful syntax
|
|
highlighting in code blocks. For a list of supported languages visit the
|
|
[Rouge project wiki](https://github.com/rouge-ruby/rouge/wiki/List-of-supported-languages-and-lexers).
|
|
Syntax highlighting is supported only in code blocks, so you can't highlight inline code.
|
|
|
|
To fence and apply syntax highlighting to a block of code, append the code language
|
|
to the opening code declaration, three back-ticks (```` ``` ````) or three tildes (`~~~`):
|
|
|
|
````markdown
|
|
```javascript
|
|
var s = "JavaScript syntax highlighting";
|
|
alert(s);
|
|
```
|
|
|
|
```python
|
|
def function():
|
|
#indenting works just fine in the fenced code block
|
|
s = "Python syntax highlighting"
|
|
print s
|
|
```
|
|
|
|
```ruby
|
|
require 'redcarpet'
|
|
markdown = Redcarpet.new("Hello World!")
|
|
puts markdown.to_html
|
|
```
|
|
|
|
```
|
|
No language indicated, so no syntax highlighting.
|
|
s = "No highlighting is shown for this line."
|
|
But let's throw in a <b>tag</b>.
|
|
```
|
|
````
|
|
|
|
The four examples above render as:
|
|
|
|
```javascript
|
|
var s = "JavaScript syntax highlighting";
|
|
alert(s);
|
|
```
|
|
|
|
```python
|
|
def function():
|
|
#indenting works just fine in the fenced code block
|
|
s = "Python syntax highlighting"
|
|
print s
|
|
```
|
|
|
|
```ruby
|
|
require 'redcarpet'
|
|
markdown = Redcarpet.new("Hello World!")
|
|
puts markdown.to_html
|
|
```
|
|
|
|
```plaintext
|
|
No language indicated, so no syntax highlighting.
|
|
s = "No highlighting is shown for this line."
|
|
But let's throw in a <b>tag</b>.
|
|
```
|
|
|
|
### Emphasis
|
|
|
|
In Markdown, you can emphasize text in multiple ways. You can italicize, bold, strikethrough,
|
|
and combine these emphasis styles together.
|
|
Strikethrough is not part of the core Markdown standard, but is part of GitLab Flavored Markdown.
|
|
|
|
Examples:
|
|
|
|
```markdown
|
|
Emphasis, aka italics, with *asterisks* or _underscores_.
|
|
|
|
Strong emphasis, aka bold, with double **asterisks** or __underscores__.
|
|
|
|
Combined emphasis with **asterisks and _underscores_**.
|
|
|
|
Strikethrough uses two tildes. ~~Scratch this.~~
|
|
```
|
|
|
|
<!-- markdownlint-disable MD050 -->
|
|
|
|
Emphasis, aka italics, with *asterisks* or _underscores_.
|
|
|
|
Strong emphasis, aka bold, with double **asterisks** or __underscores__.
|
|
|
|
Combined emphasis with **asterisks and _underscores_**.
|
|
|
|
Strikethrough uses two tildes. ~~Scratch this.~~
|
|
|
|
<!-- markdownlint-enable MD050 -->
|
|
|
|
#### Multiple underscores in words and mid-word emphasis
|
|
|
|
If this section isn't rendered correctly,
|
|
[view it in GitLab](https://gitlab.com/gitlab-org/gitlab/-/blob/master/doc/user/markdown.md#multiple-underscores-in-words).
|
|
|
|
Avoid italicizing a portion of a word, especially when you're
|
|
dealing with code and names that often appear with multiple underscores.
|
|
GitLab Flavored Markdown extends the standard Markdown standard by ignoring multiple underlines in words,
|
|
to allow better rendering of Markdown documents discussing code:
|
|
|
|
```markdown
|
|
perform_complicated_task
|
|
|
|
do_this_and_do_that_and_another_thing
|
|
|
|
but_emphasis is_desired _here_
|
|
```
|
|
|
|
<!-- vale gitlab.Spelling = NO -->
|
|
|
|
perform_complicated_task
|
|
|
|
do_this_and_do_that_and_another_thing
|
|
|
|
but_emphasis is_desired _here_
|
|
|
|
<!-- vale gitlab.Spelling = YES -->
|
|
|
|
---
|
|
|
|
If you wish to emphasize only a part of a word, it can still be done with asterisks:
|
|
|
|
```markdown
|
|
perform*complicated*task
|
|
|
|
do*this*and*do*that*and*another thing
|
|
```
|
|
|
|
perform*complicated*task
|
|
|
|
do*this*and*do*that*and*another thing
|
|
|
|
### Footnotes
|
|
|
|
Footnotes add a link to a note that are rendered at the end of a Markdown file.
|
|
|
|
To make a footnote, you need both a reference tag and a separate line (anywhere in the file) with
|
|
the note content.
|
|
|
|
Regardless of the tag names, the relative order of the reference tags determines the rendered
|
|
numbering.
|
|
|
|
<!--
|
|
The following codeblock uses HTML to skip the Vale ReferenceLinks test.
|
|
Do not change it back to a markdown codeblock.
|
|
-->
|
|
|
|
<pre class="highlight"><code>A footnote reference tag looks like this: [^1]
|
|
|
|
This reference tag is a mix of letters and numbers. [^footnote-42]
|
|
|
|
[^1]: This text is inside a footnote.
|
|
|
|
[^footnote-42]: This text is another footnote.
|
|
</code></pre>
|
|
|
|
A footnote reference tag looks like this:[^1]
|
|
|
|
This reference tag is a mix of letters and numbers.[^footnote-42]
|
|
|
|
<!--
|
|
Do not delete the single space before the [^1] and [^footnotes] references below.
|
|
These are used to force the Vale ReferenceLinks check to skip these examples.
|
|
-->
|
|
|
|
[^1]: This text is inside a footnote.
|
|
|
|
[^footnote-42]: This text is another footnote.
|
|
|
|
### Headers
|
|
|
|
```markdown
|
|
# H1
|
|
## H2
|
|
### H3
|
|
#### H4
|
|
##### H5
|
|
###### H6
|
|
|
|
Alternatively, for H1 and H2, an underline-ish style:
|
|
|
|
Alt-H1
|
|
======
|
|
|
|
Alt-H2
|
|
------
|
|
```
|
|
|
|
#### Header IDs and links
|
|
|
|
GitLab Flavored Markdown extends the standard Markdown standard so that all Markdown-rendered headers automatically
|
|
get IDs, which can be linked to, except in comments.
|
|
|
|
On hover, a link to those IDs becomes visible to make it easier to copy the link to
|
|
the header to use it somewhere else.
|
|
|
|
The IDs are generated from the content of the header according to the following rules:
|
|
|
|
1. All text is converted to lowercase.
|
|
1. All non-word text (such as punctuation or HTML) is removed.
|
|
1. All spaces are converted to hyphens.
|
|
1. Two or more hyphens in a row are converted to one.
|
|
1. If a header with the same ID has already been generated, a unique
|
|
incrementing number is appended, starting at 1.
|
|
|
|
Example:
|
|
|
|
```markdown
|
|
# This header has spaces in it
|
|
## This header has a :thumbsup: in it
|
|
# This header has Unicode in it: 한글
|
|
## This header has spaces in it
|
|
### This header has spaces in it
|
|
## This header has 3.5 in it (and parentheses)
|
|
```
|
|
|
|
Would generate the following link IDs:
|
|
|
|
1. `this-header-has-spaces-in-it`
|
|
1. `this-header-has-a-in-it`
|
|
1. `this-header-has-unicode-in-it-한글`
|
|
1. `this-header-has-spaces-in-it-1`
|
|
1. `this-header-has-spaces-in-it-2`
|
|
1. `this-header-has-3-5-in-it-and-parentheses`
|
|
|
|
Emoji processing happens before the header IDs are generated. The
|
|
emoji is converted to an image, which is then removed from the ID.
|
|
|
|
### Horizontal Rule
|
|
|
|
Create a horizontal rule by using three or more hyphens, asterisks, or underscores:
|
|
|
|
```markdown
|
|
Three or more hyphens,
|
|
|
|
---
|
|
|
|
asterisks,
|
|
|
|
***
|
|
|
|
or underscores
|
|
|
|
___
|
|
```
|
|
|
|
### Images
|
|
|
|
Examples:
|
|
|
|
<!--
|
|
The following codeblock uses HTML to skip the Vale ReferenceLinks test.
|
|
Do not change it back to a markdown codeblock.
|
|
-->
|
|
|
|
<pre class="highlight"><code>Inline-style (hover to see title text):
|
|
|
|
|
|
|
|
Reference-style (hover to see title text):
|
|
|
|
![alt text1][logo]
|
|
|
|
[logo]: img/markdown_logo.png "Title Text"
|
|
</code></pre>
|
|
|
|
<!--
|
|
DO NOT change the name of markdown_logo.png. This file is used for a test in
|
|
spec/controllers/help_controller_spec.rb.
|
|
-->
|
|
|
|
Inline-style (hover to see title text):
|
|
|
|
|
|
|
|
Reference-style (hover to see title text):
|
|
|
|
<!--
|
|
The example below uses an in-line link to pass the Vale ReferenceLinks test.
|
|
Do not change to a reference style link.
|
|
-->
|
|
|
|
|
|
|
|
In the rare case where you must set a specific height or width for an image,
|
|
you can use the `img` HTML tag instead of Markdown and set its `height` and
|
|
`width` parameters.
|
|
|
|
#### Videos
|
|
|
|
If this section isn't rendered correctly, [view it in GitLab](https://gitlab.com/gitlab-org/gitlab/-/blob/master/doc/user/markdown.md#videos).
|
|
|
|
Image tags that link to files with a video extension are automatically converted to
|
|
a video player. The valid video extensions are `.mp4`, `.m4v`, `.mov`, `.webm`, and `.ogv`:
|
|
|
|
```markdown

|
|
|
|
Similar to videos, link tags for files with an audio extension are automatically converted to
|
|
an audio player. The valid audio extensions are `.mp3`, `.oga`, `.ogg`, `.spx`, and `.wav`:

### Inline HTML
|
|
|
|
> Allowing `rel="license"` [introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/20857) in GitLab 14.6.
|
|
|
|
To see the second example of Markdown rendered in HTML,
|
|
[view it in GitLab](https://gitlab.com/gitlab-org/gitlab/-/blob/master/doc/user/markdown.md#inline-html).
|
|
|
|
You can also use raw HTML in your Markdown, and it usually works pretty well.
|
|
|
|
See the documentation for HTML::Pipeline's [SanitizationFilter](https://github.com/jch/html-pipeline/blob/v2.12.3/lib/html/pipeline/sanitization_filter.rb#L42)
|
|
class for the list of allowed HTML tags and attributes. In addition to the default
|
|
`SanitizationFilter` allowlist, GitLab allows `span`, `abbr`, `details` and `summary` elements.
|
|
`rel="license"` is allowed on links to support the [Rel-License microformat](https://microformats.org/wiki/rel-license) and license attribution.

|
|
|
|
It's still possible to use Markdown inside HTML tags, but only if the lines containing Markdown
|
|
are separated into their own lines:
|
|
|
|
```html
|
|
<dl>
|
|
<dt>Markdown in HTML</dt>
|
|
<dd>Does *not* work **very** well. HTML tags work, in most cases.</dd>
|
|
|
|
<dt>Markdown in HTML</dt>
|
|
<dd>
|
|
|
|
Does *not* work **very** well. HTML tags work, in most cases.
|
|
|
|
</dd>
|
|
</dl>
|
|
```
|
|
|
|
<!--

To see the second Markdown example rendered in HTML,
|
|
[view it in GitLab](https://gitlab.com/gitlab-org/gitlab/-/blob/master/doc/user/markdown.md#details-and-summary).
|
|
|
|
Content can be collapsed using HTML's [`<details>`](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/details)
|
|
and [`<summary>`](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/summary)
|
|
tags. For example, collapse a long log file so it takes up less screen space.
|
|
|
|
```html
|
|
<p>
|
|
<details>
|
|
<summary>Click this to collapse/fold.</summary>
|
|
|
|
These details <em>remain</em> <strong>hidden</strong> until expanded.
|

|
|
---
|
|
|
|
Markdown inside these tags is also supported.
|
|
|
|
NOTE:
|
|
If your Markdown isn't rendering correctly, try adding
|
|
`{::options parse_block_html="true" /}` to the top of the page, and add
|
|
`markdown="span"` to the opening summary tag like this: `<summary markdown="span">`.
|
|
|
|
Remember to leave a blank line after the `</summary>` tag and before the `</details>` tag,
|
|
as shown in the example:
|
|
|
|
````html
|
|
<details>
|
|
<summary>Click this to collapse/fold.</summary>
|
|
|
|
These details _remain_ **hidden** until expanded.
|
|
|
|
```
|
|
PASTE LOGS HERE
|
|
```
|
|
|
|
</details>
|
|
````

|
### Line breaks
|
|
|
|
A line break is inserted (a new paragraph starts) if the previous text is
|
|
ended with two newlines, like when you press <kbd>Enter</kbd> twice in a row. If you only
|
|
use one newline (select <kbd>Enter</kbd> once), the next sentence remains part of the
|
|
same paragraph. Use this approach if you want to keep long lines from wrapping, and keep
|
|
them editable:
|
|
|
|
```markdown
|
|
Here's a line for us to start with.
|
|
|
|
This longer line is separated from the one above by two newlines, so it is a *separate paragraph*.
|
|
|
|
This line is also a separate paragraph, but...
|
|
These lines are only separated by single newlines,
|
|
so they *do not break* and just follow the previous lines
|
|
in the *same paragraph*.
|
|
```
|
|
|
|
Here's a line for us to start with.
|
|
|
|
This longer line is separated from the one above by two newlines, so it is a *separate paragraph*.
|
|
|
|
This line is also a separate paragraph, but...
|
|
These lines are only separated by single newlines,
|
|
so they *do not break* and just follow the previous lines
|
|
in the *same paragraph*.
|
|
|
|
#### Newlines
|
|
|
|
GitLab Flavored Markdown adheres to the Markdown specification for handling
|
|
[paragraphs and line breaks](https://spec.commonmark.org/current/).
|
|
|
|
A paragraph is one or more consecutive lines of text, separated by one or
|
|
more blank lines (two newlines at the end of the first paragraph), as [explained above](#line-breaks).
|
|
|
|
Need more control over line breaks or soft returns? Add a single line break
|
|
by ending a line with a backslash, or two or more spaces. Two newlines in a row create a new
|
|
paragraph, with a blank line in between:
|
|
|
|
```markdown
|
|
First paragraph.
|
|
Another line in the same paragraph.
|
|
A third line in the same paragraph, but this time ending with two spaces.{space}{space}
|
|
A new line directly under the first paragraph.
|
|
|
|
Second paragraph.
|
|
Another line, this time ending with a backslash.\
|
|
A new line due to the previous backslash.
|
|
```
|
|
|
|
### Links
|
|
|
|
You can create links two ways: inline-style and reference-style. For example:
|
|
|
|
<!--
|
|
The following codeblock uses HTML to skip the Vale ReferenceLinks test.
|
|
Do not change it back to a markdown codeblock.
|
|
-->
|
|
|
|
<pre class="highlight"><code>- This line shows an [inline-style link](https://www.google.com)
|
|
- This line shows a [link to a repository file in the same directory](permissions.md)
|
|
- This line shows a [relative link to a file one directory higher](../index.md)
|
|
- This line shows a [link that also has title text](https://www.google.com "This link takes you to Google!")
|
|
|
|
Using header ID anchors:
|
|
|
|
- This line links to [a section on a different Markdown page, using a "#" and the header ID](permissions.md#project-features-permissions)
|
|
- This line links to [a different section on the same page, using a "#" and the header ID](#header-ids-and-links)
|
|
|
|
Using references:
|
|
|
|
- This line shows a [reference-style link, see below][Arbitrary case-insensitive reference text]
|
|
- You can [use numbers for reference-style link definitions, see below][1]
|
|
- Or leave it empty and use the [link text itself][], see below.
|
|
|
|
Some text to show that the reference links can follow later.
|
|
|
|
[arbitrary case-insensitive reference text]: https://www.mozilla.org/en-US/
|
|
[1]: https://slashdot.org
|
|
[link text itself]: https://www.reddit.com
|
|
</code></pre>
|
|
|
|
- This line shows an [inline-style link](https://www.google.com)
|
|
- This line shows a [link to a repository file in the same directory](permissions.md)
|
|
- This line shows a [relative link to a file one directory higher](../index.md)
|
|
- This line shows a [link that also has title text](https://www.google.com "This link takes you to Google!")
|
|
|
|
Using header ID anchors:
|
|
|
|
- This line links to [a section on a different Markdown page, using a "#" and the header ID](permissions.md#project-features-permissions)
|
|
- This line links to [a different section on the same page, using a "#" and the header ID](#header-ids-and-links)
|
|
|
|
Using references:
|
|
|
|
<!--
|
|
The example below uses in-line links to pass the Vale ReferenceLinks test.
|
|
Do not change to reference style links.
|
|
-->
|
|
|
|
- This line is a [reference-style link, see below](https://www.mozilla.org/en-US/)
|
|
- You can [use numbers for reference-style link definitions, see below](https://slashdot.org)
|
|
- Or leave it empty and use the [link text itself](https://www.reddit.com), see below.
|
|
|
|
Some text to show that the reference links can follow later.
|
|
|
|
NOTE:
|
|
Relative links do not allow the referencing of project files in a wiki
|
|
page, or a wiki page in a project file. The reason: a wiki is always
|
|
in a separate Git repository in GitLab. For example, `[I'm a reference-style link](style)`
|
|
points the link to `wikis/style` only when the link is inside of a wiki Markdown file.
|
|
|
|
#### URL auto-linking
|
|
|
|
GitLab Flavored Markdown auto-links almost any URL you put into your text:
|
|
|
|
```markdown
|
|
- https://www.google.com
|
|
- https://www.google.com
|
|
- ftp://ftp.us.debian.org/debian/
|
|
- smb://foo/bar/baz
|
|
- irc://irc.freenode.net/
|
|
- http://localhost:3000
|
|
```
|
|
|
|
<!-- vale gitlab.Spelling = NO -->
|
|
|
|
- <https://www.google.com>
|
|
- <https://www.google.com>
|
|
- <ftp://ftp.us.debian.org/debian/>
|
|
- <smb://foo/bar/baz>
|
|
- <irc://irc.freenode.net/>
|
|
- <http://localhost:3000>
|
|
|
|
<!-- vale gitlab.Spelling = YES -->
|
|
### Lists
|
|
|
|
You can create ordered and unordered lists.
|
|
|
|
For an ordered list, add the number you want the list
|
|
to start with, like `1.`, followed by a space, at the start of each line for ordered lists.
|
|
After the first number, it does not matter what number you use. Ordered lists are
|
|
numbered automatically by vertical order, so repeating `1.` for all items in the
|
|
same list is common. If you start with a number other than `1.`, it uses that as the first
|
|
number, and counts up from there.
|
|
|
|
Examples:
|
|
|
|
```markdown
|
|
1. First ordered list item
|
|
2. Another item
|
|
- Unordered sub-list.
|
|
1. Actual numbers don't matter, just that it's a number
|
|
1. Ordered sub-list
|
|
1. Next ordered sub-list item
|
|
4. And another item.
|
|
```
|
|
|
|
<!--
|
|
The "2." and "4." in the example above are changed to "1." below, to match the style
|
|
standards on docs.gitlab.com.
|
|
See https://docs.gitlab.com/ee/development/documentation/styleguide/index.html#lists
|
|
-->
|
|
|
|
1. First ordered list item
|
|
1. Another item
|
|
- Unordered sub-list.
|
|
1. Actual numbers don't matter, just that it's a number
|
|
1. Ordered sub-list
|
|
1. Next ordered sub-list item
|
|
1. And another item.
|
|
|
|
For an unordered list, add a `-`, `*` or `+`, followed by a space, at the start of
|
|
each line for unordered lists, but you should not use a mix of them.
|
|
|
|
```markdown
|
|
Unordered lists can:
|
|
|
|
- use
|
|
- minuses
|
|
|
|
They can also:
|
|
|
|
* use
|
|
* asterisks
|
|
|
|
They can even:
|
|
|
|
+ use
|
|
+ pluses
|
|
```
|
|
|
|
<!--
|
|
The "*" and "+" in the example above are changed to "-" below, to match the style
|
|
standards on docs.gitlab.com.
|
|
See https://docs.gitlab.com/ee/development/documentation/styleguide/index.html#lists
|
|
-->
|
|
|
|
Unordered lists can:
|
|
|
|
- use
|
|
- minuses
|
|
|
|
They can also:
|
|
|
|
- use
|
|
- asterisks
|
|
|
|
They can even:
|
|
|
|
- use
|
|
- pluses
|
|
|
|
---
|
|
|
|
If a list item contains multiple paragraphs, each subsequent paragraph should be indented
|
|
to the same level as the start of the list item text.
|
|
|
|
Example:
|
|
|
|
```markdown
|
|
1. First ordered list item
|
|
|
|
Second paragraph of first item.
|
|
|
|
1. Another item
|
|
```
|
|
|
|
1. First ordered list item
|
|
|
|
Second paragraph of first item.
|
|
|
|
1. Another item
|
|
|
|
---
|
|
|
|
If the first item's paragraph isn't indented with the proper number of spaces,
|
|
the paragraph appears outside the list, instead of properly indented under the list item.
|
|
For example:
|
|
|
|
```markdown
|
|
1. First ordered list item
|
|
|
|
Paragraph of first item.
|
|
|
|
1. Another item
|
|
```
|
|
|
|
1. First ordered list item
|
|
|
|
Paragraph of first item.
|
|
|
|
1. Another item
|
|
|
|
---
|
|
|
|
Ordered lists that are the first sub-item of an unordered list item must have a preceding blank line if they don't start with `1.`.
|
|
|
|
**Good**
|
|
|
|
```markdown
|
|
- Unordered list item
|
|
|
|
5. First ordered list item
|
|
```
|
|
|
|
**Bad**
|
|
|
|
```markdown
|
|
- Unordered list item
|
|
5. First ordered list item
|
|
```
|
|
|
|
---
|
|
|
|
CommonMark ignores blank lines between ordered and unordered list items, and considers them part of a single list. These are rendered as a
|
|
_[loose](https://spec.commonmark.org/0.30/#loose)_ list. Each list item is enclosed in a paragraph tag and, therefore, has paragraph spacing and margins.
|
|
This makes the list look like there is extra spacing between each item.
|
|
|
|
For example:
|
|
|
|
```markdown
|
|
- First list item
|
|
- Second list item
|
|
|
|
- A different list
|
|
```
|
|
|
|
CommonMark ignores the blank line and renders this as one list with paragraph spacing.
|
|
|
|
### Superscripts / Subscripts
|
|
|
|
CommonMark and GitLab Flavored Markdown don't support the Redcarpet superscript syntax ( `x^2` ).
|
|
Use the standard HTML syntax for superscripts and subscripts:
|
|
|
|
```html
|
|
The formula for water is H<sub>2</sub>O
|
|
while the equation for the theory of relativity is E = mc<sup>2</sup>.
|
|
```
|
|
|
|
<!-- vale gitlab.Spelling = NO -->
|
|
|
|
The formula for water is H<sub>2</sub>O
|
|
while the equation for the theory of relativity is E = mc<sup>2</sup>.
|
|
|
|
<!-- vale gitlab.Spelling = YES -->
|
|
|
|
### Keyboard HTML tag
|
|
|
|
The `<kbd>` element is used to identify text that represents user keyboard input. Text surrounded by `<kbd>` tags is typically displayed in the browser's default monospace font.
|
|
|
|
```html
|
|
Press <kbd>Enter</kbd> to go to the next page.
|
|
```
|
|
|
|
Press <kbd>Enter</kbd> to go to the next page.
|
|
|
|
### Tables
|
|
|
|
Tables are not part of the core Markdown specification, but are part of GitLab Flavored Markdown.
|
|
|
|
#### Markdown
|
|
|
|
1. The first line contains the headers, separated by "pipes" (`|`).
|
|
1. The second line separates the headers from the cells.
|
|
- The cells can contain only empty spaces, hyphens, and
|
|
(optionally) colons for horizontal alignment.
|
|
- Each cell must contain at least one hyphen, but adding more hyphens to a
|
|
cell does not change the cell's rendering.
|
|
- Any content other than hyphens, whitespace, or colons is not allowed
|
|
1. The third, and any following lines, contain the cell values.
|
|
- You **can't** have cells separated over many lines in the Markdown, they must be kept to single lines,
|
|
but they can be very long. You can also include HTML `<br>` tags to force newlines if needed.
|
|
- The cell sizes **don't** have to match each other. They are flexible, but must be separated
|
|
by pipes (`|`).
|
|
- You **can** have blank cells.
|
|
1. Column widths are calculated dynamically based on the content of the cells.
|
|
|
|
Example:
|
|
|
|
```markdown
|
|
| header 1 | header 2 | header 3 |
|
|
| --- | --- | --- |
|
|
| cell 1 | cell 2 | cell 3 |
|
|
| cell 4 | cell 5 is longer | cell 6 is much longer than the others, but that's ok. It eventually wraps the text when the cell is too large for the display size. |
|
|
| cell 7 | | cell 9 |
|
|
```
|
|
|
|
| header 1 | header 2 | header 3 |
|
|
| --- | --- | --- |
|
|
| cell 1 | cell 2 | cell 3 |
|
|
| cell 4 | cell 5 is longer | cell 6 is much longer than the others, but that's ok. It eventually wraps the text when the cell is too large for the display size. |
|
|
| cell 7 | | cell 9 |
|
|
|
|
Additionally, you can choose the alignment of text in columns by adding colons (`:`)
|
|
to the sides of the "dash" lines in the second row. This affects every cell in the column:
|
|
|
|
```markdown
|
|
| Left Aligned | Centered | Right Aligned |
|
|
| :--- | :---: | ---: |
|
|
| Cell 1 | Cell 2 | Cell 3 |
|
|
| Cell 4 | Cell 5 | Cell 6 |
|
|
```
|
|
|
|
| Left Aligned | Centered | Right Aligned |
|
|
| :--- | :---: | ---: |
|
|
| Cell 1 | Cell 2 | Cell 3 |
|
|
| Cell 4 | Cell 5 | Cell 6 |
|
|
|
|
[In GitLab itself](https://gitlab.com/gitlab-org/gitlab/-/blob/master/doc/user/markdown.md#tables),
|
|
the headers are always left-aligned in Chrome and Firefox, and centered in Safari.
|
|
|
|
You can use HTML formatting to adjust the rendering of tables. For example, you can
|
|
use `<br>` tags to force a cell to have multiple lines:
|
|
|
|
```markdown
|
|
| Name | Details |
|
|
| --- | --- |
|
|
| Item1 | This text is on one line |
|
|
| Item2 | This item has:<br>- Multiple items<br>- That we want listed separately |
|
|
```
|
|
|
|
| Name | Details |
|
|
| --- | --- |
|
|
| Item1 | This text is on one line |
|
|
| Item2 | This item has:<br>- Multiple items<br>- That we want listed separately |
|
|

You can use HTML formatting in GitLab itself to add [task lists](#task-lists) with checkboxes,
|
|
but they do not render properly on `docs.gitlab.com`:
|
|
|
|
```markdown
|
|
| header 1 | header 2 |
|
|
| --- | --- |
|
|
| cell 1 | cell 2 |
|
|
| cell 3 | <ul><li> - [ ] Task one </li><li> - [ ] Task two </li></ul> |
|
|
```
|
|
|
|
##### Copy and paste from a spreadsheet

|
|
If you're working in spreadsheet software (for example, Microsoft Excel, Google
|
|
Sheets, or Apple Numbers), GitLab creates a Markdown table when you copy and paste
|
|
from a spreadsheet. For example, suppose you have the
|
|
following spreadsheet:
|
|
|
|
|
|
|
|
Select the cells and copy them to your clipboard. Open a GitLab Markdown
|
|
entry and paste the spreadsheet:
|
|
|
|
|
|
|
|
#### JSON
|
|
|
|
> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/86353) in GitLab 15.3.
|
|
|
|
To render tables with JSON code blocks, use the following syntax:
|
|
|
|
````markdown
|
|
```json:table
|
|
{}
|
|
```
|
|
````
|
|
|
|

|
|
|
The `items` attribute is a list of objects representing the data points.
|
|
|
|
````markdown
|
|
```json:table
|
|
{
|
|
"items" : [
|
|
{"a": "11", "b": "22", "c": "33"}
|
|
]
|
|
}
|
|
```
|
|
````
|
|
|
|
To specify the table labels, use the `fields` attribute.
|
|
|
|
````markdown
|
|
```json:table
|
|
{
|
|
"fields" : ["a", "b", "c"],
|
|
"items" : [
|
|
{"a": "11", "b": "22", "c": "33"}
|
|
]
|
|
}
|
|
```
|
|
````
|
|
|
|
Not all elements of `items` must have corresponding values in `fields`.
|
|
|
|
````markdown
|
|
```json:table
|
|
{
|
|
"fields" : ["a", "b", "c"],
|
|
"items" : [
|
|
{"a": "11", "b": "22", "c": "33"},
|
|
{"a": "211", "c": "233"}
|
|
]
|
|
}
|
|
```
|
|
````
|
|
|
|
When `fields` is not explicitly specified, the labels are picked from the first element of `items`.
|
|
|
|
````markdown
|
|
```json:table
|
|
{
|
|
"items" : [
|
|
{"a": "11", "b": "22", "c": "33"},
|
|
{"a": "211", "c": "233"}
|
|
]
|
|
}
|
|
```
|
|
````
|
|
|
|
You can specify custom labels for `fields`.
|
|
|
|
````markdown
|
|
```json:table
|
|
{
|
|
"fields" : [
|
|
{"key": "a", "label": "AA"},
|
|
{"key": "b", "label": "BB"},
|
|
{"key": "c", "label": "CC"}
|
|
],
|
|
"items" : [
|
|
{"a": "11", "b": "22", "c": "33"},
|
|
{"a": "211", "b": "222", "c": "233"}
|
|
]
|
|
}
|
|
```
|
|
````
|
|
|
|
You can enable sorting for individual elements of `fields`.
|
|
|
|
````markdown
|
|
```json:table
|
|
{
|
|
"fields" : [
|
|
{"key": "a", "label": "AA", "sortable": true},
|
|
{"key": "b", "label": "BB"},
|
|
{"key": "c", "label": "CC"}
|
|
],
|
|
"items" : [
|
|
{"a": "11", "b": "22", "c": "33"},
|
|
{"a": "211", "b": "222", "c": "233"}
|
|
]
|
|
}
|
|
```
|
|
````
|
|
|
|
You can use the `filter` attribute to render a table with content filtered dynamically by user input.
|
|
|
|
````markdown
|
|
```json:table
|
|
{
|
|
"fields" : [
|
|
{"key": "a", "label": "AA"},
|
|
{"key": "b", "label": "BB"},
|
|
{"key": "c", "label": "CC"}
|
|
],
|
|
"items" : [
|
|
{"a": "11", "b": "22", "c": "33"},
|
|
{"a": "211", "b": "222", "c": "233"}
|
|
],
|
|
"filter" : true
|
|
}
|
|
```
|
|
````
|
|
|
|
By default, every JSON table has the caption `Generated with JSON data`.
|
|
You can override this caption by specifying the `caption` attribute.
|
|
|
|
````markdown
|
|
```json:table
|
|
{
|
|
"items" : [
|
|
{"a": "11", "b": "22", "c": "33"}
|
|
],
|
|
"caption" : "Custom caption"
|
|
}
|
|
```
|
|
````
|
|
|
|
If JSON is invalid, an error occurs.
|
|
|
|
````markdown
|
|
```json:table
|
|
{
|
|
"items" : [
|
|
{"a": "11", "b": "22", "c": "33"}
|
|
],
|
|
}
|
|
```
