Configuration

The gitiles.config file supporting the site contains several configuration options.

Core configuration

Fixed time zone

By default dates are formatted including the local user time zone as that matches git tools. Some users/administrators may prefer normalizing to a particular timezone so times are directly comparable without doing timezone arithmetic.

Setting fixedTimeZone to a valid Java TimeZone ID causes all dates in the UI to be implicitly converted to this timezone, and the now-redundant timezone offset to be dropped from the output.

[gitiles]
  fixedTimeZone = UTC

Cross-Origin Resource Sharing (CORS)

Gitiles sets the Access-Control-Allow-Origin header to the HTTP origin of the client if the client's domain matches a regular expression defined in allowOriginRegex.

[gitiles]
  allowOriginRegex = http://localhost

By default allowOriginRegex is unset, denying all cross-origin requests.

Markdown

Disabling markdown

Markdown can be completely disabled by setting render to false.

[markdown]
  render = false

Markdown size

Markdown files are limited by default to 5 MiB of input text per file. This limit is configurable, but should not be raised beyond available memory.

[markdown]
  inputLimit = 5M

Image size

Referenced images are inlined as base64 encoded URIs. The image limit places an upper bound on the byte size of input.

[markdown]
  imageLimit = 256K

Extensions

The following extensions can be enabled/disabled in the markdown section:

  • githubFlavor: enable extensions that mirror GitHub Flavor Markdown behavior. Default is true.

  • autolink: automatically convert plain URLs and email addresses into links. Default follows githubFlavor.

  • blocknote: Gitiles style note/promo/aside blocks to raise awareness to important content. Default false.

  • ghthematicbreak: accept -- for <hr>, like GitHub Flavor Markdown. Default follows githubFlavor.

  • multicolumn: Gitiles extension to layout content in a 12 cell grid, delinated by section headers. Default false.

  • namedanchor: Gitiles extension to extract named anchors using #{id} syntax. Default false.

  • safehtml: Gitiles extension to accept very limited HTML; for security reasons all other HTML is dropped regardless of this setting. Default follows githubFlavor.

  • smartquote: Gitiles extension to convert single and double quote ASCII characters to Unicode smart quotes when in prose. Default false.

  • strikethrough: strikethrough text with GitHub Flavor Markdown style ~~. Default follows githubFlavor.

  • tables: format tables with GitHub Flavor Markdown. Default follows githubFlavor.

  • toc: Gitiles extension to replace [TOC] in a paragraph by itself with a server-side generated table of contents extracted from section headers. Default true.

IFrames

IFrame support requires markdown.safehtml to be true.

IFrame source URLs can be whitelisted by providing a list of allowed URLs. URLs ending with a / are treated as prefixes, allowing any source URL beginning with that prefix.

[markdown]
  allowiframe = https://google.com/

URLs not ending with a / are treated as exact matches, and only those source URLs will be allowed.

[markdown]
  allowiframe = https://example.com
  allowiframe = https://example.org

If the list has a single entry with the value true, all source URLs will be allowed.

[markdown]
  allowiframe = true

Google Analytics

Google Analytics can be enabled on every rendered markdown page by adding the Property ID to the configuration file:

[google]
  analyticsId = UA-XXXX-Y
