(mostly <a href="/wiki/Wikipedia:WikiGnome" title="Wikipedia:WikiGnome">WikiGnomes</a>) are going around Wikipedia working to clean up <a href="/wiki/Special:LintErrors" title="Special:LintErrors">lint errors</a>, which are sorted by severity into one of three priority levels: high, medium, and low, which relate to how badly the error affects page display, or how much the page display changed when MediaWiki parsing changed. You are welcome to join in this effort. Here are some hints: </p> <ul><li>Each lint error page has a help link in the upper-right corner that links to a page with more information about that type of error.</li> <li>Lint error pages are sorted approximately in the order of the most recently edited being listed last. Some error pages are sorted better than others.</li> <li>Lint error pages are not necessarily complete. When a new lint error type is discovered and a page is made for it, or when the definition of a type of lint error is changed, that lint error page starts empty and is gradually filled by a process that can take several weeks or months.</li> <li>Every page's <a href="/wiki/Help:Page_information" title="Help:Page information">page information</a> details how many errors of each type of lint error that page has. This section is near the end and is omitted if there are no lint errors.</li> <li>For each lint error, the count maxes out at 20 in any one page.</li> <li>It is <a href="/wiki/Wikipedia:REFACTOR" class="mw-redirect" title="Wikipedia:REFACTOR">OK to edit</a> other people's <a href="/wiki/Help:User_page" class="mw-redirect" title="Help:User page">User</a> and User <a href="/wiki/Help:Talk_pages" title="Help:Talk pages">talk pages</a>, and other people's comments on talk pages; but if you do, please see <a href="/wiki/Wikipedia:Talk_page_guidelines#Editing_others'_comments" title="Wikipedia:Talk page guidelines">Wikipedia:Talk page guidelines § Editing others' comments</a> for guidance. <ul><li>Don't change the words of other editors.</li> <li>Try to preserve the appearance.</li> <li>It is OK to change the appearance in some cases if it preserves the original intent. <ul><li>It is OK to fix a missing end tag, such as a <code class="nowrap" style=""><small></code> tag improperly closed with another <code class="nowrap" style=""><small></code> tag instead of <code class="nowrap" style=""></small></code>, even if this changes the appearance. This is especially true if the missing end tag affects anything beyond the scope of the comment in which it appears. If a user's comment in the middle of the page causes subsequent comments or sections to be indented wrong, or be bolded or italicized or in a different font, you should insert the missing end tag, even if the page has "always" been wrong. <ul><li><strong>Fixing such errors has become more urgent</strong>; after MediaWiki's July 2018 switch to a new linter package, many pages that used to look fine despite errors in them now show terrible appearance and <a href="/wiki/MOS:ACCESS" class="mw-redirect" title="MOS:ACCESS">accessibility</a> problems, such as fonts becoming smaller and smaller (or larger and larger) the further down the page you scroll, due to successive unclosed sizing elements.</li></ul></li> <li>In a discussion about wiki or HTML markup, unclosed tags are sometimes used. For example, in a discussion about the <code class="nowrap" style=""><div></code> tag, the tag might not be surrounded by <code class="nowrap"><<a href="/wiki/Help:Wikitext#Nowiki" title="Help:Wikitext">nowiki</a>></code> markup, so the <code class="nowrap" style=""><div></code> tag will be taken as markup with a missing end tag instead of simply displaying the tag. In cases like this, it is helpful to insert <code class="nowrap" style=""><nowiki>...</nowiki></code> around the unescaped markup, which changes the display, shows the intent of the original comment, and fixes the missing end tag or other errors resulting from the unescaped markup.</li></ul></li> <li>In a discussion about errors, for example, "Why does the display get messed up when I use [<var style="padding-right: 1px;">some bad markup</var>]", it's often best to leave the bad markup in place, since otherwise the discussion won't make any sense.</li> <li>Especially on User and User talk pages, try to minimize disruption by getting your fix right on the first try. "<a href="/wiki/Help:Show_preview" title="Help:Show preview">Show preview</a>" is your friend. <ul><li>By default, editing a base user talk page will trigger a <a href="/wiki/Help:Notifications" title="Help:Notifications">notification</a> to the user, which can be annoying and should not be done in large batches. To avoid this, use a flagged bot account, and also flag the edit as <a href="/wiki/Help:Minor_edit" title="Help:Minor edit">minor</a>, which will bypass the "You have new messages" notification.</li></ul></li></ul></li> <li>See also <a href="/wiki/Wikipedia:HTML_5#Obsolete_elements_and_attributes" class="mw-redirect" title="Wikipedia:HTML 5">WP:HTML 5 § Obsolete elements and attributes</a> for a list of invalid tags and attributes, which you can detect with CSS. <a href="#User_CSS_tool:_lint.css">See below</a>.</li> <li>Some Lint errors caused by user signatures and Template substitutions are present across a large number of pages. It is more efficient to fix such errors in a bot task rather than manual edits. You can use <a href="/wiki/Regular_expression" title="Regular expression">regex</a>-based <a href="/wiki/H:INSOURCE" class="mw-redirect" title="H:INSOURCE">insource search</a> to identify patterns of errors that can be fixed by bots.</li> <li>If you find a lint error in an article, consider the possibility that the error was introduced by a recent edit that should be reverted. This is especially true for <a href="/wiki/Special:LintErrors/deletable-table-tag" title="Special:LintErrors/deletable-table-tag">Table tag that should be deleted</a> and <a href="/wiki/Special:LintErrors/fostered" title="Special:LintErrors/fostered">Fostered content</a> lint errors, where careless deletion of table end markup (<code>|}</code>) can cause either of these lint errors. The solution to a lint error may be to revert one or more edits.</li> <li>Occasionally, large pages show up on <a href="/wiki/Special:LintErrors" title="Special:LintErrors">lint error lists</a> without there actually being any errors on the pages themselves. If there's nothing obviously wrong with a listed page, and <a href="/wiki/Help:Page_information" title="Help:Page information">page information</a>, <a href="#User_Javascript_tool:_lintHint">lintHint</a>, and <a href="/wiki/Special:ExpandTemplates" title="Special:ExpandTemplates">template expansion</a> show no errors, it will often disappear from the list on its own after a while. Editors can usually expedite this by <a href="/wiki/Wikipedia:NULLEDIT" class="mw-redirect" title="Wikipedia:NULLEDIT">null editing</a> the page in question.</li></ul> <div class="mw-heading mw-heading2 ext-discussiontools-init-section"><h2 id="Reports" data-mw-thread-id="h-Reports"><span data-mw-comment-start="" id="h-Reports"></span>Reports<span data-mw-comment-end="h-Reports"></span></h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Wikipedia:Linter&action=edit&section=8" title="Edit section: Reports"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <ul><li>The Firefly Tools table, <a href="https://iw.toolforge.org/fireflytools/linter/enwiki" class="extiw" title="toolforge:fireflytools/linter/enwiki">Outstanding linter errors on enwiki</a>, is a chart with rows for the namespaces and columns for the type of lint error, with each cell in the chart listing the number of errors (maxed at 20 for each error type per article).

installing and using lintHint, a <a href="/wiki/Wikipedia:Gadget" title="Wikipedia:Gadget">gadget</a> coded in <a href="/wiki/JavaScript" title="JavaScript">JavaScript</a> that identifies lint errors in a document in the wiki editor. </p><p>You can run lintHint repeatedly in the same edit session to see if you fixed the errors and to relocalize the error pointers. Error pointers are relative to the top of the article, so if you correct errors from the bottom up, you won't need to run lintHint again to relocalize error pointers. </p><p>The lintHint tool does not expand relative links when the page is in editing mode. For example, in <a href="/wiki/Portal:Science" title="Portal:Science">Portal:Science</a>, <code>{{/Header}}</code> really means <code>{{Portal:Science/Header}}</code>, but lintHint does not do this. To get lintHint to work, you can manually expand relative links. You can also use <a href="/wiki/Special:ExpandTemplates" title="Special:ExpandTemplates">Expand templates</a>, and enter the page name in <code>Context title</code> and copy part or all of the page into <code>Input wikitext</code>. Then click <code>OK</code> and then press <code>lintHint</code>. Expand templates will often help lintHint localize and identify lint errors listed on Page information but that lintHint doesn't find on its own. </p><p>After editing, pages are rechecked for lint errors, usually within seconds, but in the past sometimes delayed for hours. If lintHint says you fixed one or more lint errors, you probably did fix them, even if page information and the specific lint errors page aren't updated yet. As noted, however, lintHint can't detect errors in unexpanded relative links. </p> <div class="mw-heading mw-heading2 ext-discussiontools-init-section"><h2 id="User_CSS_tool:_lint.css" data-mw-thread-id="h-User_CSS_tool:_lint.css"><span data-mw-comment-start="" id="h-User_CSS_tool:_lint.css"></span>User CSS tool: lint.css<span data-mw-comment-end="h-User_CSS_tool:_lint.css"></span></h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Wikipedia:Linter&action=edit&section=13" title="Edit section: User CSS tool: lint.css"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>You can easily employ <a href="/wiki/Wikipedia:User_CSS" class="mw-redirect" title="Wikipedia:User CSS">user CSS</a> to detect a lot of "linty" old HTML 4 code in pages as you read, if you're a <a href="/wiki/Wikipedia:WikiGnome" title="Wikipedia:WikiGnome">WikiGnome</a> who likes to do cleanup.
