參見版本歷史

HotCat is a JavaScript extension of the MediaWiki user interface. It augments the category bar with quick links to remove, change, or add categories. It can be activated in the "Gadgets" tab of Special:Preferences.

瀏覽器的相容性

實際上的版本$1應該可以在所有維基媒體的支援JavaScript瀏覽器裏正常運作。

較舊的版本

針對維基媒體的較舊的版本,HotCat的2.34版已經測試過,並且已知是可以在下列的瀏覽器中正常運作:

Firefox 2 and later OK
Internet Explorer 8 OK
Internet Explorer 7 OK
Internet Explorer 6 OK Win XP Pro, SP2. IE6 sometimes "forgets" to redraw the
category list when editors are closed. Resizing the window a
little bit makes it redraw the contents correctly.
Konqueror OK
Chrome OK
Opera 9.50 and later OK Opera 9.50 on Win XP, SP2. Opera 9.50 sometimes does not
redraw the suggestion list correctly. Resizing the window a
little bit makes it update its display correctly.
Not OK on earlier Opera versions(severe bugs in the rendering
make at least the suggestion list completely unusable).
Safari 5/Mac OK Safari 5.0.4 (6533.20.27) on Mac OS X 10.6.2
Safari 4/Mac OK
Safari 3/Mac unknown presumed OK
Safari 2/Mac unknown
Safari 3/Win OK Safari 3.0.4 & 3.1.1 on Win XP Pro, SP2
Safari 2/Win don't care Early Safari versions for Windows are known to be buggy.
We don't cater to broken browsers (well, except IE :-)
Users should upgrade their browsers to Safari 3.
Firefox 1.5 unknown needed?
IE/Mac don't care IE for the Mac is obsolete. Use Safari instead.
Internet Explorer 5.5 OK

如果JavaScript被關閉,當然它不會做任何事。如果JavaScript有被開啟,但Ajax是關閉的,HotCat仍然能夠用來增加、變更或移除單一分類,但,它無法提出分類的建議,而且,多方變更的模式無法正常運作。

如何開啟

要打開或關閉HotCat,前往你的偏好設定。要先確保你已登入,然後在你的頁面的右上角單擊偏好設定

一旦你已經看到你的偏好設定,前往「小工具」標籤頁,然後往下捲到「分類工具」這一節。勾選"HotCat",打勾就代表小工具已經啟動,沒打勾代表它沒被啟動。往下捲到下面的底部,然後點選「儲存」,你會得到一行綠色的“你的偏好設定已被儲存”的訊息。現在,你可以回到你最初的頁面。你可能需要重新整理你的頁面。

追踪

As of Version 2.38

Edits made on Wikimedia Commons are tagged in the recent changes (Tag: HotCat), they can be filtered. Please note that for unverified edits (for example if the file description page has been afterwards manually edited) no tag will be applied, to prevent abuse (adding additionally a manual change-tag to such edits is currently not possible). In such cases the (previous) ordinary text tag "using HotCat" is added to the summary.

Other wikis may use other tags or ordinary tracking methods. The German language Wikipedia uses e.g. "HC: %change%" (prefixed).

使用者介面

Whenever a page is loaded, HotCat looks for the category bar. If there are visible categories, it adds links to easily remove, change or add categories. Due to space constraints (and also to avoid internationalization issues), these links use symbols instead of text:

A category bar as modified by HotCat

The new links are:

  • "(−)" after a category: when clicked, the category is automatically removed.
  • "(±)" after a category: when clicked, an input field to change this category is opened.

as of Version 2.2 "(↓)" after a category: when clicked, the input field is opened, and a list of available subcategories is displayed.

as of Version 2.2 "(↑)" after a category: when clicked, the input field is opened, and a list of available parent categories is shown.

  • "(+)" at the end of the list of categories: when clicked, an input field to add a category is opened.
  • "(++)" at the front: when clicked, enters multi-change mode, allowing modifying more than one category.

Note that the "(↓)" and "(↑)" links are shown only for existing categories. Red-linked categories, i.e. non-existing categories, can have neither parent nor subcategories, and thus showing these links wouldn't make sense. Also note that it is possible that only the input box is shown when these links are clicked, but no list. That indicates that this category does not have parent categories or subcategories, respectively. See also "Search engines" below.

If HotCat can detect that a certain category is not in the page text itself but was transcluded onto the page from a template or other transclusion, it will not add these links. Only categories that are present in the wikitext of the page itself can be modified through HotCat.

移除单一分类

To remove a category, simply click the "(−)" link next to the category name. If the page does indeed contain this category, HotCat will remove it automatically. It will:

  1. open a new window or tab in your browser with the current page opened for editing,
  2. hide the whole edit form, so that you cannot edit,
  3. edit the page to remove the category, and
  4. 保存该页面。

修改一個分類

To change a category, click the "(±)" link next to the category name. This will open the input box where you can enter a new category name.

建立一個新的分類

To add a category, click the "(+)" link at the end of the category line. This will open the input box where you can enter a new category name.

输入框

The input box of HotCat
The input box of HotCat

The input box of HotCat is very simple: a text field to enter the new category name, an indicator icon, and an "OK" and a "Cancel" button.

The indicator icon tells you whether or not the category name you've entered exists. A icon means that there is no such category yet. You can still add the category, but it will show up as a red link, and you should, after having added the category, click that red link and enter a brief description and parent categories to this new category. A icon shows that there already is a category with the name you've entered.

When you start typing, HotCat will display a list of suggestions above or below the text input field. Clicking one of these suggestions will copy it into the text field. Double-clicking a suggestion is the same as clicking once and then clicking the "OK" button: HotCat will add the double-clicked suggestion automatically. The suggestion list is populated by the search engine chosen in the selector between the list and the text input field.

In the example shown here, we've entered "Alps of", and HotCat presents us with a list of possible completions. The first suggestion has already been copied into the text box, but the added text is selected, so that it will be overwritten when we keep on typing. Entering " S" reduces the suggestion list accordingly.

Clicking on "Alps of Switzerland" will then copy that into the text field and close the suggestion list (since there are no more suggestions, i.e., categories beginning with "Alps of Switzerland" as a prefix).

Clicking the "Cancel"-button would now abort the operation, clicking "OK" would tell HotCat to go on and add the chosen category.

Sort keys

You can even give a sort key together with the category. Just write after the category name a vertical bar ("|"), followed by the sort key under which the page shall be sorted within that category’s list.

If no sort key is given, HotCat will preserve an already existing key if a category is changed.

As of Version 2.2 : To explicitly remove a sort key, just write a vertical bar ("|") without anything following it:

  • Input "Foo" will add a new category "Foo" without sort key, or change an existing category to "Foo", preserving the sort key.
  • Input "Foo|Key" will add a new category "Foo" or change an existing category to "Foo", using the given sort key "Key" in both cases.
  • Input "Foo|" (with a trailing vertical bar) will add a new category "Foo" without sort key, or change an existing category to "Foo", removing any sort key the changed category might have had.

Search engines

Between the suggestion list and the text input field, there is a search engine selector to select the search method which populates the suggestion list. HotCat supports any number of search engines.

The MediaWiki servers offer two general ways to search for categories. The first is through the page list of the wiki. This list is always up to date, but is strictly alphabetic and also case-sensitive, so "similar" suggestions (for instance, suggesting "Bláhnjúkur" when "Blahn" was entered) are not shown. The second search engine is the search index that is also used by the "search" box on all pages. It does find "similar" suggestions and is not case-sensitive, but as its index is updated only at intervals, it may not show newly created categories.

HotCat by default combines these two search engines to get the best of both worlds: similar suggestions and newly created categories. However, to do so, it must make two requests to the server. Normally, that’s not a problem, but if it turns out to be too slow on a slow connection, you can use the engine selector to choose which search engine you want to use. It is also possible to configure which search engine HotCat should use by default.


As of Version 2.2 : In addition to these general searches, HotCat also provides two additional, more specialized search engines. A first one can be used to search for subcategories of the category given by the current input. A second one returns the parent categories of the category given by the current input. Both engines may return empty results, in which case no suggestion list is shown. (For instance, if the current input is a name of a non-existing category, or if a category has no subcategories). In this case, the search engine is automatically reset to the default search engine after the first non-deleting input.

Note that there is no way to "page" through a list of subcategories. The script just tries to get as many subcategories as it can (normally at most 500, the limits for administrators are somewhat higher). Subcategory queries can also be slow if a category contains many items (not just many subcategories), and the input field is made non-editable for the time of the request. If it doesn't become editable in reasonable time, just click cancel.

For the technically inclined: the problem is that subcategory continuation queries appear not to work in the MediaWiki API. On the (hidden) category Category:Media with locations, the API returns (with a limit of 5000) only the first 1540 subcategories of more than 4800 that exist, and continuation queries seem to return no further subcategories at all. Related bug reports on this are bugzilla:1211 and bugzilla:23682. Until this is fixed, there will be no paging through subcategories in HotCat.

Category redirects and disambiguations

HotCat tries to automatically resolve redirects between categories when the "OK"-button is clicked (or when a suggestion is double-clicked). If the selected category X is a redirect to another category Y, HotCat will automatically add the category Y instead of X.

Similar processing is done for disambiguation categories. If HotCat detects that the chosen category is actually a disambiguation category, it will present again a suggestion list, this time filled from the categories being disambiguated. If, for instance, you entered "Buzet" as the category and then clicked "OK", you would see the suggestion list shown here, as these are all the categories mentioned at Category:Buzet.

Note that this suggestion list has no search engine selector, as it is not the result of a search. The suggestions are taken directly from the links on the disambiguation category Category:Buzet.

Diff screens

If you change only a single category HotCat will—in its default configuration—perform the edit immediately.

Sometimes you might still want to check what HotCat does before saving the modified page. To do so, use "control-clicking". Hold down the Control key (marked Ctrl on many keyboards; on German keyboards, it’s often Strg; on the Mac, use the  Cmd key) while clicking with the mouse on the "(−)" link, or on the "OK" button, or while double-clicking a suggestion from the list. Or submit the edit by typing Ctrl+ Enter ( Cmd+ Enter on a Mac). In that case, HotCat will show you a diff screen instead of saving the edit automatically. Examine the changes at your leisure, and then click "Save page" to commit the changes.

HotCat can be configured such that it present a diff screen for all edits it makes; see hotcat_no_autocommit in the section on user configuration. Additionally, it can be configured such that even if that setting is false and thus single-category changes are executed immediately, it still presents a diff screen for single category deletions (a click on the "(–)" link). That may be a useful setting to avoid that mis-clicks suddenly make changes the user maybe didn't intend. See hotcat_del_needs_diff in the user configuration section.

In multi-change mode, submitting category changes through HotCat always presents you with a diff screen, where you can see exactly what will be changed if you submit the edit.

Making more than one category change

In multi-change mode, category changes are saved only when the "save" button is clicked.

The user interface of HotCat is minimalistic on purpose and geared towards making interactions simple and fast. When you just click on a "(−)" link to remove a category, the edit is—in the default setting of HotCat—executed right away, and likewise when you submit a single category addition or change.

Still HotCat fully supports changing more than one category at once. If you click the "(++)" link at the beginning of the category line, HotCat will enter its multi-change mode. The "(++)" link is replaced by a "save" button, and all changes you make from now on will be written to the page only when that button is clicked. Initially, this button may appear disabled. It is enabled only when there are indeed category changes that need saving.

In multi-change mode, changes are reflected on the page view, but are saved only when the "save" button is clicked.

This multi-change mode is also entered automatically if you have one category input box open and, while it is still open, add, change, or remove another category.

In multi-change mode, submitting a category change or removal will not perform the edit immediately. Instead, the change will only be reflected on the screen, allowing you to make more category changes. HotCat will add "(×)" links after each changed category. This is an "undo" link; it'll undo the last action on that category. Category removals are indicated by striking through the category name.

As of Version 2.2 : Unless overridden by a user configuration, HotCat will also highlight unsaved category changes by changing the background of the category link.

Once the "save" button is clicked, HotCat will make all the changes, and then opens the page in a diff screen, showing the changes made. The changes are at that point not yet saved! Review the changes to make sure that the script did what you intended it to do, and the submit the edit like any other edit you'd make.

Note that while HotCat normally automatically submits single category changes, it will never do so when operating in multi-change mode. It will always open a screen showing the changes made, which you should review before submitting the edit manually.

User configuration

Some aspects of HotCat can be configured by the user. All of these configurations can be done by adding a few lines to your common.js allowing the gadget to work independently of the skin selected.

  • The user may change the behavior of HotCat when making a single category change. By default, HotCat automatically saves such edits. If you'd rather not have that and prefer to see the edit screen after HotCat has made it changes, add the following to your skin-specific user JS:
JSconfig.keys['HotCatNoAutoCommit'] = true;

window.hotcat_no_autocommit = true;
  • The user may set the timeout between a keypress and the refresh of the suggestion list. The default is 100 milliseconds. This can be changed as follows:
JSconfig.keys['HotCatDelay'] = 200; // Or whatever other value you prefer

window.hotcat_suggestion_delay = 200; // Or whatever other value you prefer
  • The user may change the width of the edit box. The default (and minimum size) is 40 characters. If you find that too small, add the following to your skin-specific user JS:
JSconfig.keys['HotCatEditBoxWidth'] = 80; // Or whatever other value you prefer

window.hotcat_editbox_width = 80; // Or whatever other value you prefer
  • The user may define the default search engine that HotCat shall use to display the suggestions. Possible values are "pagelist", "searchindex", or "combined", corresponding to the three implemented search engines.
JSconfig.keys['HotCatSuggestions'] = "pagelist"; // Or "searchindex", or "combined" (the default)

window.hotcat_suggestions = "pagelist"; // Or "searchindex", or "combined" (the default)
  • The user may suppress the search engine selector altogether to always use a particular search engine (the one defined by the setting above).
JSconfig.keys['HotCatFixedSuggestions'] = true;

window.hotcat_suggestions_fixed = true;

as of Version 2.2 The user may determine the background color HotCat uses to visually mark unsaved category changes in multi-change mode.

JSconfig.keys['HotCatChangedBackground'] = 'yellow'; // Or any other valid color specification.

window.hotcat_changed_background = 'yellow'; // Or any other valid color specification.

The default is '#F8CCB0', a light salmon pink that was chosen because it isn't used in any of the skins deployed at WMF sites and thus really stands out. If you don't want any background highlighting, set it to 'transparent'.

as of Version 2.2 The user may suppress the "(↓)" and "(↑)" links. Most of the time, these are not needed because the suggestion list is shown automatically when a category is modified, and the subcategories or parent categories can then be obtained via the search engine selector. However, there’s a caveat: if there are no suggestions, the list and the selector may not be shown after all.

JSconfig.keys['HotCatUseCategoryLinks'] = false; // Default is true.

window.hotcat_use_category_links = false; // Default is true.

as of Version 2.3 The size of the suggestion list is configurable from 5 to 30 lines:

JSconfig.keys['HotCatListSize'] = 20; // Or any integer value from 5 to 30; default is 10.

window.hotcat_list_size = 20; // Or any integer value from 5 to 30; default is 10.

as of Version 2.4 HotCat can be configured whether or not single-category changes should be marked as minor edit. Up to version 2.3, all single-category changes were automatically marked as minor. As of version 2.4, there is a configuration setting for this. It can be set site-wide by setting HotCat.single_minor, for instance in the /local_defaults configuration file (see below). Users can configure this setting for themselves, possibly overriding the site-wide default configuration setting for this.

JSconfig.keys['HotCatMinorSingleChanges'] = false; // Or true

window.hotcat_single_changes_are_minor = false; // Or true

as of Version 2.7 (2011-05-30) Normally, HotCat respects the user’s watchlist preferences. In particular, if the user has set the "Add pages I edit to my watchlist" preference, categorizing a page through HotCat will put the page on the user’s watchlist. If a user wants to use this preference in general, but have it not apply to categorizations made through HotCat, the user can do so by defining a configuration setting:

JSconfig.keys['HotCatDontAddToWatchlist'] = true; // Default is false

window.hotcat_dont_add_to_watchlist = true; // Default is false
If this setting is false (the default), HotCat will respect the preference settings for adding pages to the watchlist. If this HotCat setting is true, it will never add pages to the user’s watchlist.

as of Version 2.20 Users can define whether or not HotCat presents a diff screen when the "(–)" link is clicked to remove a single category. A diff screen may be useful for this case because it helps prevent accidental category removal through mis-clicks.

JSconfig.keys['HotCatDelNeedsDiff'] = true; // Or false

window.hotcat_del_needs_diff = true; // Or false
If this setting is true, HotCat will not submit such changes immediately but will always present a diff screen. If it is false, it will not do so but will submit the category removal immediately.

The user may also change some aspects of the display of the interface using monobook.css or other skin-specific CSS (e.g. vector.css).

as of Version 2.2 The links to modify categories (i.e., "(+)", "(−)", etc.) are enclosed in a <span> with a CSS class named "hotcatlink". Users can use this class to style the links as they like. For instance, to reduce the font size of these links to make them smaller, one could use the following CSS code:

.hotcatlink {
  font-size: 80%; /* Or some other value */
}
To change the color or these links, one might use something like
.hotcatlink a {
  color: brown; /* Or any other color specification */
}
Or one could highlight these links when the mouse hovers over them:
.hotcatlink a:hover {
  background-color : #87CEFA; /* A light blue */
}

Shortcuts

As of Version 2.22 HotCat provides editors with the ability to define shortcuts. Shortcuts are supposed to be short character sequences that are to be replaced by long category names or parts of category names.

Shortcuts can be defined by any logged-in user to their own liking. There are no default shortcuts.

Defining shortcuts

You can define shortcuts in your own common.js user script page. To do so, copy the following block to the beginning of your common.js:

(function(){function setShortCuts(){if (!window.HotCat.addShortcuts) return; window.HotCat.addShortcuts({
 // Do not modify above. Add your shortcuts below
 // Shortcut : Replacement, both inside single quotes. If the replacement shall contain a single quote, write it as \'

 // ADD YOUR SHORTCUTS HERE. DO NOT FORGET THE COMMA AT THE END OF EACH LINE.

 // Do not modify below
' ':""});} if (window.HotCat && window.HotCat.runWhenReady) window.HotCat.runWhenReady(setShortCuts); else $('body').on('hotcatSetupCompleted',setShortCuts);})();

Ignore all the cryptic stuff at the beginning and at the end. It’s just some magic incantations to make your shortcuts known to HotCat. Below the line saying "ADD YOUR SHORTCUTS HERE", you can add your own shortcuts.

Each shortcut definition is one line: first the shortcut, in single quotes. Then a colon (":"), and then the replacement, again in single quotes. Finally, a comma. If either the shortcut or the replacement shall contain a single quote, write it as \'.

For instance, adding the following two lines

 'ppl':'people',
 'tpp':'Template:Painting possible',

defines two shortcuts: the shortcut "ppl" will be replaced by "people", and the shortcut "tpp" will be replaced by "Template:Painting possible".

If you add these two example shortcuts, the whole block that you insert in common.js looks like this:

(function(){function setShortCuts(){if (!window.HotCat.addShortcuts) return; window.HotCat.addShortcuts({
 // Do not modify above. Add your shortcuts below
 // Shortcut : Replacement, both inside single quotes. If the replacement shall contain a single quote, write it as \'

 // ADD YOUR SHORTCUTS HERE. DO NOT FORGET THE COMMA AT THE END OF EACH LINE.
 'ppl':'people',
 'tpp':'Template:Painting possible',

 // Do not modify below
' ':""});} if (window.HotCat && window.HotCat.runWhenReady) window.HotCat.runWhenReady(setShortCuts); else $('body').on('hotcatSetupCompleted',setShortCuts);})();

Using shortcuts

User entered "#pnc", a shortcut defined to be replaced by "Paintings not categorised by year"…
… and then clicked "OK". If the edit is saved now, HotCat will insert Category:Paintings not categorised by year.
Shortcut "#ppl", defined as "people", displays suggestions starting with "People…"

Wherever HotCat asks you for a category name, you can now use such shortcuts. However, you have to tell HotCat that the next few characters will be a shortcut. To do so, type a hash character ("#"). The hash was chosen because it cannot appear in category names. So, instead of entering "people", you can now just write "#ppl“. HotCat will replace that automatically by "people" when you save the new category. Shortcuts can be used anywhere in a category name.

You can also use shortcuts as parts of words. If you wanted to write "Peoples", you could now use the shortcut and write "#[ppl]s". Here, the name of the shortcut must be inside square brackets, because if you wrote "#ppls", HotCat would go look for a shortcut "ppls", and since that doesn't exist, would not change anything. If you write "#[ppl]s", HotCat knows that the shortcut is just the part between the square brackets, and can replace the shortcut correctly, yielding "peoples".

Unknown shortcuts are not replaced at all. If you type "#foo", that will be left unchanged (with these two example shortcuts).

HotCat generally tries to leave your input as it is. It will do the replacements for its suggestion list, and when you save the category editor. So, if you type "#ppl“, you'll have "#ppl" in the category input box, but you'll be shown category suggestions starting with "People…". If you now select one of these suggestions, it'll replace whatever you had typed. To get back your input, hit the escape key (normally esc on your keyboard, typically in the upper left corner of the keyboard).

Localization

HotCat uses only a few texts for some of its buttons, plus a few other texts for its edit summaries. The button texts can be localized by placing the localizations in appropriate subpages of MediaWiki:Gadget-HotCat.js; for instance, the German texts can be found at MediaWiki:Gadget-HotCat.js/de.

Put only the messages that you see translated in MediaWiki:Gadget-HotCat.js/de in a localization file here at the Commons. Other messages for edit summaries and so on belong into the /local_defaults file at your wiki (see below). Edit summaries should always be in the wiki’s main language, even if the user’s interface language is set to something else, so that other contributors have a chance to understand what the summaries mean. By putting translations for the edit summaries in /local_defaults at a foreign wiki, that wiki can customize the edit summaries in any way without changing the English default messages here at the Commons.

As of Version 2.17 , HotCat supports complex plural forms in its HotCat.messages.multi_change message. (That is one of those that belongs in /local_defaults, as it is used in edit summaries.) Its default value (in English) is "$1 categories"; the "HotCat.messages.multi_change" is replaced by a number strictly greater than 1. For most languages, simply translating this string will be good enough. However, for languages that have several plural forms such as the dual, this may be insufficient. If your language has several plural forms, you can set HotCat.messages.multi_change to an array containing the various forms as strings (don't forget to include the "HotCat.messages.multi_change" as appropriate in each form). The array must be set up as is appropriate for your language’s implementation of mw.language.convertPlural(). You can check that e.g. in the MediaWiki source code. On older MediaWiki installations that do not have mw.language.convertPlural(), HotCat will simply use the last element of the array.

Note that if you want to be sure that mw.language.convertPlural() exists, you should make sure that the "mediawiki.language" module is loaded (it doesn't appear to be a default module in MediaWiki 1.19). To do so, set up your gadget definition for HotCat in MediaWiki:Gadgets-definition on your wiki as follows:
*HotCat[ResourceLoader|dependencies=mediawiki.language]|HotCat.js
If you already had an entry for HotCat, you may then need to purge the MediaWiki:Gadgets-definition page to make that work.

Installing HotCat on another wiki

There are two ways to use HotCat on another wiki: either copy the file and install it locally or hotlink to the Commons version and only do localizations locally.

If you copy HotCat, you have the advantage that all code resides locally, and no script imports from other domains will occur. Also, you can modify your HotCat as you see fit.

If you include HotCat via hotlinking, you can be sure to always have the most recent version of the gadget, but the script will be loaded from a *.wikimedia.org domain (that is, you have to enable cross-origin resource sharing in your server for it to work). Also note that HotCat has been developed and tested on WMF sites. If your wiki uses a skin that significantly differs from the WMF skins, HotCat may not work out of the box. In that case, copying HotCat and modifying it locally as needed would be the preferred method. But for WMF sites, hotlinking to the Commons version is certainly a viable approach.

HotCat should work in all skins that are part of MediaWiki and that are in use on the WMF projects. It may or may not work properly on other custom skins. HotCat does not depend on jQuery. It also does not depend on the JSconfig stuff from our MediaWiki:Common.js; that is completely optional, and HotCat can be used and configured without it.

Copying HotCat

If you want to install HotCat as a copy on another Wiki, follow the procedure outlined here.

  1. Enable the API on your wiki. You don't need to enable the write API. $wgGroupPermissions["*"]["read"] may be set to false if you have a private Wiki (one that allows reading only if logged in).
  2. Make sure you have the Gadgets extension installed and enabled.
  3. Get HotCat from MediaWiki:Gadget-HotCat.js.
  4. Localize the message texts in that file (all at the beginning of the file in the HotCat object).
  5. Install that file, possibly modified as outlined in steps 3 and 4, on your Wiki as MediaWiki:Gadget-HotCat.js.
  6. Write a definition for it in MediaWiki:Gadget-HotCat (on your Wiki), and add it to MediaWiki:Gadgets-definition (also on your Wiki).
  7. Go to Special:Preferences on your Wiki and check the gadgets section. HotCat should appear there. Select it and save your preferences.
  8. 完成。

If you want to include HotCat on a public WMF Wiki (Wikipedia, Wikinews, or other WMF project), you may skip steps 1 and 2.

HotCat makes use of jQuery in a few places, but can also run without jQuery being present. To start itself, HotCat uses either jQuery(document).ready() (preferred). If your wiki provides neither, you'll have to change the startup of HotCat as appropriate for your wiki. As of version 2.16, HotCat does not depend on ajax.js anymore.

Using the Commons version of HotCat on another wiki

If you want to set up your wiki to use the Commons version of HotCat directly ("hotlinking"), follow these steps:

  1. Make sure the server has the appropriate cross-origin resource sharing settings enabled
  2. Create a local page "MediaWiki:Gadget-HotCat.js" on your wiki with the contents of en:MediaWiki:Gadget-HotCat.js.
  3. Set up that local "MediaWiki:Gadget-HotCat.js" as a gadget by adding it to the MediaWiki:Gadgets-definition page.
  4. Write a local file "MediaWiki:Gadget-HotCat.js/local_defaults". In that file, modify the settings and messages in the HotCat object as appropriate. (Translate the messages into the wgContentLanguage of your wiki in that file.)
  5. Optionally, write local files "MediaWiki:Gadget-HotCat.js/lang", where lang is some language code ("en" for English, "fr" for French, and so on). In those files, localize the messages, tooltips, and search engine names to the appropriate language for users having wgUserLanguage != wgContentLanguage.

That’s it. When you then enable the gadget, you should have a working HotCat. An example installation using this method exists at the German Wikiversity. See file v:de:MediaWiki:Gadget-HotCat.js for the import and v:de:MediaWiki:Gadget-HotCat.js/local defaults for the localizations, plus v:de:MediaWiki:Gadget-HotCat and the change here to install it as a gadget. At Wikiversity, there is also a user-language localization for English at v:de:MediaWiki:Gadget-HotCat.js/en. Use that file as a model for your own localizations; or copy the corresponding localization from the Commons to your wiki.

Translations

As of Version 2.21 (December 2012)

Translations are loaded from Wikimedia Commons by default. You can disable this if you prefer loading translations from a local sub page. To disable this, set the variable window.hotcat_translations_from_commons to false before importing the HotCat script. The /local_defaults file will always come from the local wiki regardless of this setting.

// Load translation from local subpage, not from Commons.
window.hotcat_translations_from_commons = false;

Version 2.4 to Version 2.20 :

Translations are loaded from a local sub page by default, but you can choose to load translations of the user interface from Commons instead. To do so, set the variable window.hotcat_translations_from_commons to true before importing the HotCat script. The /local_defaults file is, will always come from the local wiki regardless of this setting.

window.hotcat_translations_from_commons = true; // Make HotCat load its interface from the Commons

// Then import the script from the commons, as in the first step.

Upload form

As of Version 2.4

You can, if you load HotCat from Commons, switch off HotCat for the upload form (by default, it will be active both on pages and on upload form). To switch off HotCat for upload forms, set the following in your local configuration file (/local_defaults):

HotCat.upload_disabled = true;

Blacklist

As of Version 2.5 , HotCat incorporates a "blacklist" that can be used to disable certain categories in HotCat altogether. Blacklisted categories cannot be added, removed, or changed through the user interface of HotCat; blacklisted categories do not show up in the suggestion list, and if entered manually, the "OK" button of the editor is disabled. Trying to submit a change from an existing category to a blacklisted category is treated as a cancellation of the edit; i.e., the original category is preserved.

The blacklist is a single regular expression that should match blacklisted category titles. If your wiki has no blacklisted categories, leave HotCat.blacklist set to null. To enable a blacklist, set it to a meaningful regular expression. The English Wikipedia uses HotCat.blacklist = /\bstubs?$/, blacklisting all categories ending with the word "stub" or "stubs". You can set the blacklist as appropriate in your /local_defaults configuration file.

The English Wikipedia blacklists these categories because they are normally added through templates. HotCat already did not allow modifying such categories prior to V2.5, but it was still possible to manually add such categories through HotCat.

Running code once HotCat is fully initialized

There may be rare occurrences where you want to add your own JavaScript code to run after HotCat has been loaded and initialized.

As of Version 2.41 (August 2018)

HotCat fires a hook called hotcat.ready that you can add callback functions to, for executing your own code after HotCat is ready.

// Add this to MediaWiki:Gadget-HotCat.js/local_defaults
mw.hook('hotcat.ready').add(function () {
  $('#catlinks').css({ backgroundColor: 'pink' }); // Horrid; just as an example.
});

Version 2.14 to Version 2.40

HotCat provides a method runWhenReady to register code a callback once HotCat is ready. The runWhenReady() function is part of the HotCat global object, and takesone parameter, which is a function.

On pages where HotCat is disabled or has problems, the registered functions will not be called.

// Add this to MediaWiki:Gadget-HotCat.js/local_defaults
window.HotCat.runWhenReady(function () {
  $('#catlinks').css({ backgroundColor: 'pink' }); // Horrid; just as an example.
});

This method requires that the window.HotCat exists and is defined. Therefore, this can only be used from /local_defaults, which loads when window.HotCat is define.


Before Version 2.14

Before Version 2.14, this ability did not exist.

Intercepting the page edit HotCat will make

HotCat internally uses a form to submit its category edits to the servers. {{{1}}} , HotCat exposes this form such that user code may intercept the edit.

The form has the ID hotcatCommitForm, and by registering an onsubmit event handler on the form, you can intercept the edit and modify it before it is finally sent to the servers. You can even block the edit, if you so wish.

Perhaps the simplest way to register an onsubmit handler is using jQuery:

// Assuming you have jQuery, and $ referes to window.jQuery:
$('body').on( 'submit', '#hotcatCommitForm', function (evt) {
  alert ("HotCat edit hook");
  return true;
});

If your event handler returns false, the form submission will be aborted; the edit will not be sent to the server. Note that you must use the hotcatCommitForm selector as described: HotCat creates this form dynamically when it starts up, so a simple $('#hotcatCommitForm') might not yet find the form.

If you don't have jQuery or don't want to use it, you should install your onsubmit handler inside a runWhenReady() hook.

The hotcatCommitForm has the same structure as a normal edit form: it has a textarea named wpTextbox1, a summary named wpSummary, and so on. Your hook can modify the form in any way it likes, but it can, of course, also break the form completely, causing the form submission to fail. If you use the jQuery method shown above to register your event handler, the variable this will refer to the form itself inside the event handler.

The following example shows a possible use of this: make HotCat auto-save always, even if multiple categories are changed:

mw.loader.using("mediawiki.user", function () {
  $('body').on( 'submit', '#hotcatCommitForm', function () {
    // The variable "this" refers to the form. Its fields can be accessed directly, e.g.
    // this.wpTextbox1 gives you the textarea containing the page text of the edit.
    var submitType = this.wpDiff;
    if (submitType && (!this.oldid || this.oldid.value == '0')) {
      // Switch form submission from diff to save. Don't do this if "oldid" is set to anything but '0':
      // that indicates an edit conflict with yourself, and in that case you really, really do want
      // to see the diff!
      this.wpEditToken.value = mw.user.tokens.get("csrfToken");
      submitType.name = submitType.value = 'wpSave';
    }
    return true;
  });
});

The default implementation of HotCat does not auto-save when multiple categories are changed to give the user a chance to check the edit and back out if it isn't what was intended. With the above event handler installed, edits made through HotCat will always automatically be saved directly, so use this with care!
