Monkbot task 9 was created to standardize lists in ship article infoboxen and operates primarily on the content of Category:WPSHIPS:Infobox list errors.
In the past, the WP:SHIPS infobox usage guide required unbulleted lists for reasons of limited available space and for aesthetics. Editors used a variety of other methods to create lists in infoboxes. These included <br /> line break HTML tags and the use of {{br}}, {{plainlist}} and {{unbulleted list}} templates. Problems with these methods are:
- use of
<br />and{{br}}make visually 'correct' lists that are not correct for those who use screen readers. See MOS:ACCESS §Vertical lists. - limitations in Mediawiki:Common.css, prevent
{{plainlist}}and{{unbulleted list}}from correctly rendering multi-level lists
description
Ship infoboxen are wiki-tables that contain, at a minimum, two and usually more specialized templates that provide formatting and header data for the infobox. The templates are {{infobox ship begin}} (required), {{infobox ship image}}, {{infobox service record}}, {{infobox ship career}}, {{infobox ship characteristics}}, and {{infobox ship class overview}}. For the time being, this task only operates on the last three of these though it is expected that it will eventually operate on {{infobox service record}} as well.
standardization
The task begins by standardizing the names of the infobox templates to sentence case and their canonical names if redirects are used.
setup
To constrain operation of this task to the limited area of the infobox table, task 9 hides certain characters and templates. The first step is to hide equal signs (=) in templates that are not ship infobox templates and in templates that are not either of the list templates {{plainlist}} or {{unbulleted list}} (or their redirect aliases) by replacing the equal signs with the text string __3QU4L__. Similarly, the equal sign in <ref <param>=...>, and pipes in templates and wikilinks are hidden using __3QU4L__ and __P1P3__ respectively.
Templates that are not infobox or list templates are hidden by replacing the opening and closing curly-brace pairs with __0P3N__ and __CL0S3__ respectively. Finally, list templates are hidden with __0P3N_PL_ and __CL0S3_PL_ for {{plainlist}}, and __0P3N_UB_ and __CL0S3_UB_ for {{unbulleted list}}.
All of this hiding make subsequent rules simpler.
line-break lists
Line break lists are the most common form of list in ship infoboxen. These list usually use some form of <br /> but occasionally use {{br}}. These latter are first converted to <br />. Similarly, the various forms <br>...</br>, <BR>...</BR>, </br> etc. are converted to the canonical form <br /> and where more than one of these tags is present in succession, the duplicates are removed.
When the first text in an infobox template parameter is <br />, the tag is removed. Task 9 inserts an asterisk at the start of parameter value and then replaces each occurrence of <br /> with \n*.
plainlist
Because {{plainlist}} templates were hidden during setup, unhide them by replacing __0P3N_PL_ and __CL0S3_PL_ with {{ and }}. {{plainlist}} supports the named parameters |class=, |style=, and |indent=. These parameters are not supported by unordered lists in ship infoboxen.
Except for white-space, {{plainlist}} templates must be the only text in the parameter value. Any text, even empty html comment tags (<!-- -->), before or after a {{plainlist}} will cause the value to be ignored. When this happens, all subsequent {{plainlist}} templates are also ignored. It is not expected that this limitation will be 'fixed' by this tool.
When infobox parameters hold only {{plainlist}} templates, the template markup (the {{plainlist| and }}) is removed along with any white-space between the parameter's equal sign and the first line of the {{plainlist}} content.
unbulleted list
Because {{unbulleted list}} templates were hidden during setup, unhide them by replacing __0P3N_UB_ and __CL0S3_UB_ with {{ and }}. {{unbulleted list}} supports the named parameters |class=, |style=, |indent=, |list_style=, |item_style=, and |itemn_style=. These parameters are not supported by unordered lists in ship infoboxen.
Except for white-space, {{unbulleted list}} templates must be the only text in the parameter value. Any text, even empty html comment tags (<!-- -->), before or after a {{plainlist}} will cause the value to be ignored. When this happens, all subsequent {{unbulleted list}} templates are also ignored. It is not expected that this limitation will be 'fixed' by this tool.
When infobox parameters hold only {{unbulleted list}} templates, the template markup (the {{unbulleted list| and }}) is removed along with any white-space between the parameter's equal sign and the first parameter of the {{unbulleted list}} template. The individual {{unbulleted list}} parameters are split at the pipes into an array of strings. A new string is constructed from the array by adding * and \n to each array string as it is concatenated to previous strings.
miscellaneous cleanup
Items in lists within ship infoboxen often take the form
*<digit> × <thing>
sometimes with or without on either side of ×; sometimes an x or × is used in place of ×. Non-breaking spaces are not required at the start of a list item.
Some lists in ship infoboxen prefix a list item in the item text with • (Bullet, U+2022, •) or · (Interpunct, U+00B7, ·) with or without surrounding spaces. When these are found, they are removed.
restoration
All of the above tasks being completed, task 9 unhides pipes (__P1P3__), equals (__3QU4L__), and template open (__0P3N__) and close (__CL0S3__). It then assembles a summary text to be used as an edit summary. If no lists were converted, sets Skip to true and abandons the edit.
