Style & Formatting

Markdown

All of our documentation is written in Markdown.

Semantic Linefeeds

Use semantic linefeeds. Separating each sentence with a new line makes it easy to parse diffs with the human eye.

Diff without semantic linefeeds:

-Data is taking off. This data is time series. You need a database that specializes in time series. You should check out InfluxDB.
+Data is taking off. This data is time series. You need a database that specializes in time series. You need InfluxDB.

Page frontmatter

Every documentation page includes frontmatter which specifies information about the page. Frontmatter populates variables in page templates and the site's navigation menu.

title: # Title of the page used in the page's h1
seotitle: # Page title used in the html <head> title and used in search engine results
list_title: # Title used in article lists generated using the {{< children >}} shortcode
description: # Page description displayed in search engine results
menu:
  v2_0:
    name: # Article name that only appears in the left nav
    parent: # Specifies a parent group and nests navigation items
weight: # Determines sort order in both the nav tree and in article lists
draft: # If true, will not render page on build
enterprise_all: # If true, specifies the doc as a whole is specific to InfluxDB Enterprise
enterprise_some: # If true, specifies the doc includes some content specific to InfluxDB Enterprise
cloud_all: # If true, specifies the doc as a whole is specific to InfluxDB Cloud
cloud_some: # If true, specifies the doc includes some content specific to InfluxDB Cloud
v2.x/tags: # Tags specific to each version (replace .x" with the appropriate minor version )
related: # Creates links to specific internal and external content at the bottom of the page
  - /path/to/related/article
  - https://external-link.com, This is an external link
external_url: # Used in children shortcode type="list" for page links that are external
list_note: # Used in children shortcode type="list" to add a small note next to listed links

Title usage

title

The title frontmatter populates each page's h1 header. It shouldn't be overly long, but should set the context for users coming from outside sources.

seotitle

The seotitle frontmatter populates each page's HTML title attribute. Search engines use this in search results (not the page's h1) and therefore it should be keyword optimized.

list_title

The list_title frontmatter determines an article title when in a list generated by the {{< children >}} shortcode.

menu > name

The name attribute under the menu frontmatter determines the text used in each page's link in the site navigation. It should be short and assume the context of its parent if it has one.

Page Weights

To ensure pages are sorted both by weight and their depth in the directory structure, pages should be weighted in "levels." All top level pages are weighted 1-99. The next level is 101-199. Then 201-299 and so on.

Note: _index.md files should be weighted one level up from the other .md files in the same directory.

Article headings

Use only h2-h6 headings in markdown content. h1 headings act as the page title and are populated automatically from the title frontmatter. h2-h6 headings act as section headings.

Notes and warnings

Shortcodes are available for formatting notes and warnings in each article:

{{% note %}}
Insert note markdown content here.
{{% /note %}}

{{% warn %}}
Insert warning markdown content here.
{{% /warn %}}

Enterprise Content

Many articles are unique to InfluxDB enterprise or at least contain some information specific to InfluxDB Enterprise. There are frontmatter options and an enterprise shortcode that help to properly identify this content.

All content is Enterprise-specific

If all content in an article is Enterprise-specific, set the enterprise_all frontmatter to true.

enterprise_all: true

This will display a message at the top of page indicating that the things discussed are unique to InfluxDB Enterprise.

Only some content is Enterprise-specific

If only some content in the article is enterprise specific, set the enterprise_some frontmatter to true.

enterprise_some: true

This will display a message at the top of page indicating some things are unique to InfluxDB Enterprise. To format Enterprise-specific content, wrap it in the {{% enterprise %}} shortcode:

{{% enterprise %}}
Insert enterprise-specific markdown content here.
{{% /enterprise %}}

Enterprise name

The name used to refer to InfluxData's enterprise offering is subject to change. To facilitate easy updates in the future, use the enterprise-name shortcode when referencing the enterprise product. This shortcode accepts a "short" parameter which uses the "short-name".

This is content that references {{< enterprise-name >}}.
This is content that references {{< enterprise-name "short" >}}.

Product names are stored in data/products.yml.

References to InfluxDB Enterprise are often accompanied with a link to a page where visitors can get more information about the Enterprise offering. This link is subject to change. Use the enterprise-link shortcode when including links to more information about InfluxDB Enterprise.

Find more info [here][{{< enterprise-link >}}]

InfluxDB Cloud Content

Some articles are unique to InfluxDB Cloud or at least contain some information specific to InfluxDB Cloud. There are frontmatter options and an cloud shortcode that help to properly identify this content.

All content is cloud-specific

If all content in an article is cloud-specific, set the menu in the frontmatter to v2_0_cloud (change the version number for the specific version of InfluxDB Cloud).

menu:
  v2_0_cloud:
    name: Menu item name
    # ...

The pages parent depends on where it fits in the hierarchy of the cloud documentation.

Only some content is cloud-specific

If only some content in the article is cloud-specific, set the cloud_some frontmatter to true.

cloud_some: true

This will display a message at the top of page indicating some things are unique to InfluxDB Cloud. To format cloud-specific content, wrap it in the {{% cloud %}} shortcode:

{{% cloud %}}
Insert Cloud-specific markdown content here.
{{% /cloud %}}

InfluxDB Cloud content block

The {{ cloud-msg }} shortcode creates a highlighted block of text specific to InfluxDB Cloud meant to stand out from the rest of the article content. It's format is similar to note and warning blocks.

{{% cloud-msg %}}
Insert Cloud-specific markdown content here.
{{% /cloud-msg %}}

InfluxDB Cloud name

The name used to refer to InfluxData's cloud offering is subject to change. To facilitate easy updates in the future, use the cloud-name short-code when referencing the cloud product. This shortcode accepts a "short" parameter which uses the "short-name".

This is content that references {{< cloud-name >}}.
This is content that references {{< cloud-name "short" >}}.

Product names are stored in data/products.yml.

References to InfluxDB Cloud are often accompanied with a link to a page where visitors can get more information. This link is subject to change. Use the cloud-link shortcode when including links to more information about InfluxDB Cloud.

Find more info [here][{{< cloud-link >}}]

Tabbed Content

Shortcodes are available for creating "tabbed" content (content that is changed by a users' selection). Ther following three must be used:

{{< tabs-wrapper >}}
This shortcode creates a wrapper or container for the tabbed content. All UI interactions are limited to the scope of each container. If you have more than one "group" of tabbed content in a page, each needs its own tabs-wrapper. This shortcode must be closed with {{< /tabs-wrapper >}}.

Note: The < and > characters used in this shortcode indicate that the contents should be processed as HTML.

{{% tabs %}}
This shortcode creates a container for buttons that control the display of tabbed content. It should contain simple markdown links with anonymous anchors (#). The link text is used as the button text. This shortcode must be closed with {{% /tabs %}}.

Note: The % characters used in this shortcode indicate that the contents should be processed as Markdown.

{{% tab-content %}}
This shortcode creates a container for a content block. Each content block in the tab group needs to be wrapped in this shortcode. The number of tab-content blocks must match the number of links provided in the tabs shortcode This shortcode must be closed with {{% /tab-content %}}.

Note: The % characters used in this shortcode indicate that the contents should be processed as Markdown.

Example tabbed content group

{{< tabs-wrapper >}}

{{% tabs %}}
[Button text for tab 1](#)
[Button text for tab 2](#)
{{% /tabs %}}

{{% tab-content %}}
Markdown content for tab 1.
{{% /tab-content %}}

{{% tab-content %}}
Markdown content for tab 2.
{{% /tab-content %}}

{{< /tabs-wrapper >}}

Tabbed code blocks

Shortcodes are also available for tabbed code blocks primarily used to give users the option to choose between different languages and syntax. The shortcode structure is the same as above, but the shortcode names are different:

{{< code-tabs-wrapper >}}
{{% code-tabs %}}
{{% code-tab-content %}}

{{< code-tabs-wrapper >}}

{{% code-tabs %}}
[Flux](#)
[InfluxQL](#)
{{% /code-tabs %}}

{{% code-tab-content %}}
```js
data = from(bucket: "example-bucket")
  |> range(start: -15m)
  |> filter(fn: (r) =>
    r._measurement == "mem" and
    r._field == "used_percent"
  )
```
{{% /code-tab-content %}}

{{% code-tab-content %}}
```sql
SELECT "used_percent"
FROM "telegraf"."autogen"."mem"
WHERE time > now() - 15m
```
{{% /code-tab-content %}}

{{< /code-tabs-wrapper >}}

Use the related frontmatter to include links to specific articles at the bottom of an article.

  • If the page exists inside of this documentation, just include the path to the page. It will automatically detect the title of the page.
  • If the page exists outside of this documentation, include the full URL and a title for the link. The link and title must be in that order and must be separated by a comma and a space.

High-resolution images

In many cases, screenshots included in the docs are taken from high-resolution (retina) screens. Because of this, the actual pixel dimension is 2x larger than it needs to be and is rendered 2x bigger than it should be. The following shortcode automatically sets a fixed width on the image using half of its actual pixel dimension. This preserves the detail of the image and renders it at a size where there should be little to no "blur" cause by browser image resizing.

{{< img-hd src="/path/to/image" alt="Alternate title" />}}
Notes
  • This should only be used on screenshots takes from high-resolution screens.
  • The src should be relative to the static directory.
  • Image widths are limited to the width of the article content container and will scale accordingly, even with the width explicitly set.

Truncated content blocks

In some cases, it may be appropriate to shorten or truncate blocks of content. Use cases include long examples of output data or tall images. The following shortcode truncates blocks of content and allows users to opt into to seeing the full content block.

{{% truncate %}}
Truncated markdown content here.
{{% /truncate %}}

Generate a list of children articles

Section landing pages often contain just a list of articles with links and descriptions for each. This can be cumbersome to maintain as content is added. To automate the listing of articles in a section, use the {{< children >}} shortcode.

{{< children >}}

The children shortcode can also be used to list only "section" articles (those with their own children), or only "page" articles (those with no children) using the show argument:

{{< children show="sections" >}}
<!-- OR -->
{{< children show="pages" >}}

By default, it displays both sections and pages.

Use the type argument to specify the format of the children list.

{{< children type="functions" >}}

The following list types are available:

  • articles: lists article titles as headers with the description or summary of the article as a paragraph. Article headers link to the articles.
  • list: lists children article links in an unordered list.
  • functions: a special use-case designed for listing Flux functions.

Children frontmatter

Each children list type uses frontmatter properties when generating the list of articles. The following table shows which children types use which frontmatter properties:

Frontmatter articles list functions
list_title
description
external_url
list_note

Inline icons

The icon shortcode allows you to inject icons in paragraph text. It's meant to clarify references to specific elements in the InfluxDB user interface.

{{< icon "icon-name" >}}

Below is a list of available icons (some are aliases):

  • add-cell
  • add-label
  • alert
  • calendar
  • chat
  • checkmark
  • clone
  • cloud
  • cog
  • config
  • copy
  • dashboard
  • dashboards
  • data-explorer
  • delete
  • download
  • duplicate
  • edit
  • expand
  • export
  • eye
  • eye-closed
  • eye-open
  • feedback
  • fullscreen
  • gear
  • graph
  • hide
  • influx
  • influx-icon
  • nav-admin
  • nav-config
  • nav-configuration
  • nav-dashboards
  • nav-data-explorer
  • nav-organizations
  • nav-orgs
  • nav-tasks
  • note
  • org
  • orgs
  • pause
  • pencil
  • play
  • plus
  • refresh
  • remove
  • replay
  • save-as
  • search
  • settings
  • tasks
  • toggle
  • trash
  • trashcan
  • triangle
  • view
  • wrench
  • x

InfluxDB UI left navigation icons

In many cases, documentation references an item in the left nav of the InfluxDB UI. Provide a visual example of the navigation item using the nav-icon shortcode.

{{< nav-icon "Tasks" >}}

The following case insensitive values are supported:

  • admin, influx
  • data-explorer, data explorer
  • dashboards
  • tasks
  • monitor, alerts, bell
  • cloud, usage
  • disks, load data, load-data
  • settings
  • feedback

InfluxDB UI notification messages

In some cases, documentation references a notification message that appears in the top-right corner of the InfluxDB UI. Rather than taking a screenshot of the message (that can be hard to maintain over time), use the {{< ui-message >}} shortcode.

It expects two parameters:

text (Required)
The message displayed.

color (Optional)
Sets the background color and icons used in the message. The following options are available:

  • green (default)
  • blue
  • red
{{< ui-message color="green" text="The message displayed in the notification.">}}

Flexbox-formatted content blocks

CSS Flexbox formatting lets you create columns in article content that adjust and flow based on the viewable width. In article content, this helps if you have narrow tables that could be displayed side-by-side, rather than stacked vertically. Use the {{< flex >}} shortcode to create the Flexbox wrapper. Use the {{% flex-content %}} shortcode to identify each column content block.

{{< flex >}}
{{% flex-content %}}
Column 1
{{% /flex-content %}}
{{% flex-content %}}
Column 2
{{% /flex-content %}}
{{< /flex >}}

{{% flex-content %}} has an optional width argument that determines the maximum width of the column.

{{% flex-content "half" %}}

The following options are available:

  • half (Default)
  • third
  • quarter

Reference content

The InfluxDB documentation is "task-based," meaning content primarily focuses on what a user is doing, not what they are using. However, there is a need to document tools and other things that don't necessarily fit in the task-based style. This is referred to as "reference content."

Reference content is styled just as the rest of the InfluxDB documentation. The only difference is the menu reference in the page's frontmatter. When defining the menu for reference content, use the following pattern:

# Pattern
menu:
  v<major-version-number>_<minor-version-number>_ref:
    # ...

# Example
menu:
  v2_0_ref:
    # ...

Image naming conventions

Save images using the following naming format: version-context-description.png. For example, 2-0-visualizations-line-graph.png or 2-0-tasks-add-new.png. Specify a version other than 2.0 only if the image is specific to that version.

InfluxDB API documentation

InfluxData uses Redoc to generate the full InfluxDB API documentation when documentation is deployed. Redoc generates HTML documentation using the InfluxDB swagger.yml. For more information about generating InfluxDB API documentation, see the API Documentation README.

New Versions of InfluxDB

Version bumps occur regularly in the documentation. Each minor version has its own directory with unique content. Patch versions within a minor version are updated in place.

To add a new minor version, go through the steps below. This example assumes v2.0 is the most recent version and v2.1 is the new version.

  1. Ensure your master branch is up to date:

    git checkout master
    git pull
    
  2. Create a new branch for the new minor version:

    git checkout -b influxdb-2.1
    
  3. Duplicate the most recent version's content directory:

    # From the root of the project
    cp content/v2.0 content/v2.1
    
  4. Find and replace all instances of the old version number with the new version (only within the new version directory). Be sure to find and replace both the following forms of the version number:

    v2.0 -> v2.1
    v2_0 -> v2_1
    
  5. Add the new version tag taxonomy to the config.toml in the root of the project.

    [taxonomies]
      "v2.0/tag" = "v2.0/tags"
      "v2.1/tag" = "v2.1/tags"
    
  6. Update the latest_version in data/version.yaml:

    latest_version: v2.1
    
  7. Copy the InfluxDB swagger.yml specific to the new version into the /api-docs/v<version-number>/ directory.

  8. Commit the changes and push the new branch to Github.

These changes lay the foundation for the new version. All other changes specific to the new version should be merged into this branch. Once the necessary changes are in place and the new version is released, merge the new branch into master.
