Template:Webarchive/doc

This is a documentation subpage for Template:Webarchive.
It contains usage information, categories and other content that is not part of the original template page.

This template is used on 295,000+ pages.
To avoid large-scale disruption and unnecessary server load, any changes should first be tested in this template's /sandbox or /testcases subpage, or in your own user space. The tested changes can then be added in one single edit to this template. Please consider discussing any changes on the talk page before implementing them.

Info:

This template uses Lua:

{{Webarchive/doc}} is for linking to web archiving services such as the Wayback Machine, WebCite and all other web archiving services.

This template is a replacement for

REDIRECT Template:Template link code,
REDIRECT Template:Template link code,
REDIRECT Template:Template link code and
REDIRECT Template:Template link code.

Usage

In most cases the template needs only two arguments, the archive |url= and archive |date=.

Example:

{{webarchive |url=https://web.archive.org/web/20160801000000/http://example.com |date=1 August 2016}}

Produces: Archived 1 August 2016 at the Wayback Machine

Example 2:

{{webarchive |url=https://www.webcitation.org/5eWaHRbn4?url=http://www.example.com/ |date=12 February 2009}}

Produces: Archived 12 February 2009 at WebCite

It is also common to include a |title=

Example 3:

{{webarchive |url=https://www.webcitation.org/5eWaHRbn4?url=http://www.example.com/ |date=12 February 2009 |title=Page title}}

Produces: Page title at WebCite (archived 12 February 2009)

Multiple URLs

Options

Main options

url..url10: The URL(s) to the archive service. There should always be a |url= which counts as the first url. Each |url#= can have its own numbered corresponding |date#= and |title#=. Matching of URL with date and title is done by numbers, not position. Numbers do not need to be in sequence, for example |url2= followed by |url5= works.

date..date10: The date the page was archived. The date format displayed is the same as entered. If |date= is missing the template will make a best effort to find the date by decoding the archive URL (wayback and webcite for example provide this data in the URL), and will display the date in iso format by default. However including a date is recommended for date formatting reasons, and because other tools may not have the ability to decode the date from the URL.

title..title10: The text displayed for the link. If no |title= is provided then |date= is displayed. Otherwise |title= takes precedence if both are set.

Secondary options

nolink: If set to any value, the archive service name will not be wikilinked.

format: This is a special option to support the merger of

REDIRECT Template:Template link code. It may be deprecated in the future. Because CS1|2 templates do not currently support more than one archive link, this template will tack on additional archive links to the end of a CS1|2 template output. It takes two values: |format=addlarchives or |format=addlpages. Addlarchives will display output appropriate for linking to multiple web archiving services. Addlpages will display output appropriate for linking to multiple pages at the same archive.

Examples

The number of possible examples is extensive depending on the mix of options. Some common cases follow. For more extensive testing see the testcases page.

Tracking categories

The template has a number of hidden tracking categories which may be added (via Module:Webarchive):

Category:Webarchive template wayback links (24,408): links to Wayback Machine
Category:Webarchive template webcite links (38): links to WebCite
Category:Webarchive template archiveis links (763): links to Archive.is
Category:Webarchive template other archives (105): links to known archive sites that don't have their own tracking category
Category:Webarchive template unknown archives (5): the template doesn't recognize the archive URL; this may indicate an error in the data; or the template itself needs updating to reflect a new archive site
Category:Webarchive template warnings (13): soft errors that do not prevent the template from working but leave a red message
Category:Webarchive template errors (0): errors typically requiring human intervention

Template maintenance

The following can be done to maintain the template.

Monitor tracking categories

The tracking categories for "warnings" and "errors" can be monitored to alert for any problems in the data.
The tracking category for "unknown archives" may indicate a problem in the data; for example an editor used the source URL instead of the archive URL in the |url= field.

Monitor template argument usage

This tool shows which instances of the template are using which arguments—it shows for example that |access-date= is being used by five instances in five articles. Since this is an error (the template does not support |access-date=) those five template instances should be fixed to remove the |access-date=.

Configuration: verifydates

The template can verify that dates in URLs for Wayback, WebCite, and Archive.is match the date in the |date= argument. If the dates do not match it will display the date from the URL, add a red warning message "date mismatch", and add the article to the warning tracking category.

Because the verification function adds some overhead to the template, it can optionally be globally disabled by setting the variable "verifydates = no" (see the Module source in function p.webarchive()). Note that after setting to "yes", it can take a week or more for the tracking category to be fully populated. Set to "yes" if you are searching for problems in the data that need fixing (they'll show up in the tracking category).

Configuration: maxurls

The max number of URLs is 10 but this can be changed by setting the "maxurls" variable in the p.webarchive() function. This is a global variable that will affect all instances of the template, use with caution. Reducing the number will increase the template speed and reduce resource use.
