🌐 Configure used timezone

By default, dates use Greenwich meridian (GMT/UTC).

Configure config_timezone (see supported timezone) to avoid time offsets.

Example: configuring timezone

- uses: lowlighter/metrics@latest
  with:
    config_timezone: Europe/Paris

📦 Ordering content

Content can be manually ordered using config_order option.

Example: display base.header, isocalendar, languages and stars in this specific order

- uses: lowlighter/metrics@latest
  with:
    base: header
    plugin_isocalendar: yes
    plugin_languages: yes
    plugin_stars: yes
    config_order: base.header, isocalendar, languages, stars

💡 Omitted sections will be appended at the end using default order

ℹ️ The handles to use for each plugin and sections is based on the partials/_.json of the template. It may not necessarily be the plugin id (e.g. base.header, base.activity+community, base.repositories, etc.).

🔕 Skipping repositories in plugins

Some plugins support a plugin_*_skipped option which is used to skipped repositories from result. It inherits the global option repositories_skipped which makes it easier to ignore repositories from all plugins at once.

These options support two different syntaxes:

Basic pattern matching

Skip repositories by:

• using their full handle (e.g. user/repo)
• using only their name (e.g. repo)
  • in this case, the owner may be implicitly set to current user option

Example: skipping repositories with basic pattern matching

repositories_skipped: my-repo, user/my-repo

💡 Either comma or newlines can be used to separate basic patterns

Advanced pattern matching

To enable advanced pattern matching to skip repositories, include @use.patterns at the beginning of the option value.

Skip repositories by writing file-glob patterns, with any of the supported operation:

• # to write comments
• - to exclude repositories
  • the - is implicit and may be omitted from excluding patterns
• + to include back repositories

ℹ️ metrics use isaacs/minimatch as its file-glob matcher

Example: skipping repositories with basic advanced matching

repositories_skipped: |
  @use.patterns

  # Skip a specific repository (both patterns are equivalent)
  user/repo
  -user/repo

  # Skip repositories matching a given pattern
  user/repo-*
  {user1, user2, user3}/*

  # Include back a previously skipped repository
  org/repo
  +org/include-this-repo

ℹ️ Unlike basic pattern matching, patterns are always tested against the full repository handle (the user will not be implicitly added)

⚠️ As patterns may contain commas, be sure to use newlines rather than commas as separator to ensure patterns are correctly parsed

🪛 Using presets

It is possible to reuse the same configuration across different repositories and workflows using configuration presets. A preset override the default values of inputs, and multiple presets can be provided at once through URLs or file paths.

Options resolution is done in the following order:

• default values
• presets, from first to last
• user values

Example: using a configuration preset from an url

- uses: lowlighter/metrics@latest
  with:
    config_presets: https://raw.githubusercontent.com/lowlighter/metrics/presets/lunar-red/preset.yaml

Some presets are hosted on this repository on the @presets branch and can be used directly by using their identifier prefixed by an arobase (@).

Example: using a pre-defined configuration preset

- uses: lowlighter/metrics@latest
  with:
    config_presets: "@lunar-red"

⚠️ 🔐 Tokens and options marked with ⏯️ Cannot be preset, as they suggest, cannot be preset and thus requires to be explicitly defined to be set.

ℹ️ Presets configurations use schemas to ensure compatibility between format changes

🎨 Custom CSS styling

Additional CSS can be injected using extras_css option.

Example: changing the color of h2

- uses: lowlighter/metrics@latest
  with:
    base: header
    extras_css: |
      h2 {
        color: red;
      }

💡 metrics does not use !important keyword, so use it when having trouble when styling is not applied

💡 If you make an heavy use of this option, creating a community templates may be a better alternative

⚠️ CSS styles may slightly change between releases, backward compatibility is not guaranteed!

🗳️ Custom JavaScript scripting

Additional JavaScript can be injected using extras_js option.

Example: removing all h2

- uses: lowlighter/metrics@latest
  with:
    base: header
    extras_js: |
      document.querySelectorAll("h2")?.forEach(h2 => h2.remove())

ℹ️ JavaScript is executed in puppeteer context during the rendering phase, not in metrics context. It will be possible to access document and all other features accessible like if the SVG was opened in a browser page

💡 If you make an heavy use of this option, creating a community templates may be a better alternative

⚠️ HTML elements may slightly change between releases, backward compatibility is not guaranteed!

🔲 Adjusting padding

SVG rendering is dependent on operating system, browser and fonts combination and may look different across different platforms.

It may not look like it, but computing the height of a SVG is not trivial. metrics spawns an headless browser and try to do its best to resize the result, but it may sometimes ends up in either cropped or oversized images.

Tweak config_padding option to manually adjust padding and solve this issue.

This settings supports the following format:

• 1 value for both width and height
• 2 values for width first and height second, separated by a comma (,)

💡 Both negative and positive values are allowed

Each value need to respect the following format:

• {number}
• {number} + {number}%
• {number}%

💡 Percentage based values are relative to the height computed by puppeteer

Example: add 10px padding for both width and height

- uses: lowlighter/metrics@latest
  with:
    config_padding: 10

Example: add 10px padding to height and increase it by 8%

- uses: lowlighter/metrics@latest
  with:
    config_padding: 0, 10 + 8%

Example: remove 10% from height

- uses: lowlighter/metrics@latest
  with:
    config_padding: 0, -10%

↔️ Controlling display size

Some templates may support different output display size.

A regular display size will render a medium-sized image suitable for both desktop and mobile displays, while a large one will be more suitable only for desktop and some plugins (like 📌 topics or 🏅 contributors)

The columns display will render a full-width image with automatic resizing: two columns for desktop and a single one column for mobiles.

Example: output a PNG image

- uses: lowlighter/metrics@latest
  with:
    config_display: large

💱 Configuring output format

Use config_output to change output format.

Example: output a PNG image

- uses: lowlighter/metrics@latest
  with:
    config_output: png

A JSON output can be used to retrieved collected data and use it elsewhere.

Example: output a JSON data dump

- uses: lowlighter/metrics@latest
  with:
    config_output: json

When using a PDF output, it is advised to set config_base64: yes to encode embed images in base64 in order to make self-contained documents.

Example: output a self-contained PDF document

- uses: lowlighter/metrics@latest
  with:
    markdown: TEMPLATE.md
    config_output: markdown-pdf
    config_base64: yes

✨ Render Metrics insights statically

It is possible to generate a self-contained HTML file containing ✨ Metrics insights output by using config_output: insights.

💡 Note that like ✨ Metrics insights content is not configurable, thus any other plugin option will actually be ignored

Example: output ✨ Metrics insights report

- uses: lowlighter/metrics@latest
  with:
    config_output: insights

🧶 Configuring output action

Before configuring output action, ensure that workflows permissions are properly set. These can be changed either through repository settings in Actions tab:

Or more granulary at job or workflow level.

Using commits (default)

Use output_action: commit to make the action directly push changes to committer_branch with a commit. A custom commit message can be used through committer_message.

💡 metrics will automatically ignore push events with a commit message containing [Skip GitHub Action] or Auto-generated metrics for run # to avoid infinite loops. Note that by default, GitHub already ignore events pushed by ${{ github.token }} or containing [skip ci] in commit message

Example: push output to metrics-renders branch rather than the default branch

metrics:
  permissions:
    contents: write
  steps:
    - uses: lowlighter/metrics@latest
      with:
        output_action: commit
        committer_branch: metrics-renders
        committer_message: "chore: update metrics"

Using pull requests

Use output_action: pull-request to make the action open a new pull request and push changes from the same run on it.

The last step should use either pull-request-merge, pull-request-squash or pull-request-rebase to merge changes to committer_branch.

💡 When using pull-request output action, do not forget to change filename too or previous output will be overwritten!

Example: push two outputs using a merge pull request

metrics:
  permissions:
    contents: write
    pull-requests: write
  steps:
    - uses: lowlighter/metrics@latest
      with:
        filename: my-metrics-0.svg
        output_action: pull-request

    - uses: lowlighter/metrics@latest
      with:
        filename: my-metrics-1.svg
        output_action: pull-request-merge

Using gists

Use output_action: gist to push output to a GitHub gist instead. It is required to provide a gist id to committer_gist option to make it work.

💡 This feature will use token instead of committer_token to push changes, so gists scope must be granted to the original token first

Example: push output to a gist

metrics:
  steps:
    - uses: lowlighter/metrics@latest
      with:
        output_action: gist
        committer_gist: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

Manual handling

Use output_action: none to perform custom processing with outputs. They will be available under /metrics_renders/{filename} in the runner.

Example: generate outputs and manually push them

metrics:
  permissions:
    contents: write
  steps:
    - name: Checkout repository
      uses: actions/checkout@v3
        with:
          fetch-depth: 0

    - uses: lowlighter/metrics@latest
      with:
        output_action: none

    - uses: lowlighter/metrics@latest
      run: |
        set +e
        git checkout metrics-renders
        git config user.name github-actions[bot]
        git config user.email 41898282+github-actions[bot]@users.noreply.github.com
        sudo mv /metrics_renders/* ./
        git add --all
        git commit -m "chore: push metrics"
        git push

♻️ Retrying automatically failed rendering and output action

Rendering is subject to external factors and can fail occasionally. Use retries and retries_delay options to automatically retry rendering.

Example: retry render up to 3 times (wait 5 minutes between each fail)

- uses: lowlighter/metrics@latest
  with:
    retries: 3
    retries_delay: 300

Output action is also subject to GitHub API rate-limiting and overall health status and can fail occasionally. Use retries_output_action and retries_delay_output_action options to automatically retry output action.

💡 As output action is a separate step from rendering, render step won't be called again

Example: retry output action up to 5 times (wait 2 minutes between each fail)

- uses: lowlighter/metrics@latest
  with:
    retries_output_action: 5
    retries_delay_output_action: 120

🗜️ Optimize SVG output

To reduce filesize and decrease loading time, metrics offers several optimization options, such as purging unused CSS and style minification, XML pretty-printing (which also reduce diffs between changes) and general SVG optimization (still experimental).

💡 This option is enabled by default!

Example: optimize CSS and XML

- uses: lowlighter/metrics@latest
  with:
    optimize: css, xml

Example: optimize SVG (experimental)

- uses: lowlighter/metrics@latest
  with:
    optimize: svg
    experimental_features: --optimize-svg

🐳 Faster execution with prebuilt docker images

When using lowlighter/metrics official releases as a GitHub Action, a prebuilt docker container image will be pulled from GitHub Container Registry. It allows to significantly reduce workflow execution time.

💡 This option is enabled by default!

On forks, this feature is disable to take into account any changes you made on it.

Example: using prebuilt docker image

- uses: lowlighter/metrics@latest
  with:
    use_prebuilt_image: yes
