Help:System message/fr

Un message système est un fragment de texte brut, de wikitexte, de CSS ou de JavaScript, qui peut être utilisé pour personnaliser le comportement de MediaWiki et son apparence pour chaque langue et paramètres régionaux. MediaWiki utilise des messages pour chaque partie de l'interface visible par l'utilisateur, permettant l'internationalisation et la régionalisation de l'interface utilisateur de MediaWiki, tant pour son cœur que pour ses extensions. Tous les messages utilisés dans MediaWiki sont définis dans un fichier de messages.

Redéfinir les messages sur un wiki
La valeur par défaut des messages peut être modifiée en l'éditant sur chaque wiki. Chaque message possède sa page wiki dans l'espace de noms MediaWiki avec sa clé de message pour nom de page. Par exemple, les message aboutsite est enregistré dans MediaWiki:aboutsite. Par défaut, cet espace de noms est protégé contre toute modification à moins que l'utilisateur n'ait les droits de modificateur d'interface. Une liste de tous les messages se trouve sur Special:AllMessages. Modifier les messages d'interface est très simple et se fait comme pour toute modification de page classique du wiki, mais cela reste réservé aux utilisateurs ayant les droits de modificateur d'interface, c'est à dire par défaut aux administrateurs (et aux administrateurs d'interfaces). Le tableau de Special:AllMessages contient deux colonnes : le nom du fichier du message système avec un lien pour le consulter, et le texte du message système. Le texte est séparé horizontalement pour montrer le texte par défaut au-dessus, et le texte personnalisé en-dessous. Quand un message personnalisé n'existe pas, seul le texte par défaut apparait. Pour personnaliser un message, cliquez sur le lien supérieur de la colonne de gauche (le nom du message). Le lien est en rouge si le texte par défaut est utilisé, car la page à modifier est vide.

Les liens inférieurs des cellules de la colonne de gauche pointent vers les pages de discussion relatives aux messages.

Trouver des messages et leur documentation
La façon dont chaque message est utilisé par MediaWiki, les variables disponibles, les paramètres utilisés, les limitations, etc. est exposée dans les fichiers de la [//translatewiki.net/w/i.php?title=Special:Translate&task=reviewall&group=core&language=qqq&limit=5000&action=page&filter= documentation complète en pseudo-langage qqq], suivant les recomendations pour la documentation des messages. Des pages d'explication plus longues peuvent exister pour quelques messages d'interface dans la plus ancienne.

Dans MediaWiki 1.18 et supérieur, vous pouvez trouver la clé d'un message en consultant un wiki dans en pseudo-langage de code, ce qui peut se faire en ajoutant   à l'URL, ou   si l'URL contient déjà un caractère   ([ exemple]). Tous les messages seront ensuite remplacés par leur clé de message, de façon à ce que vous puissiez identifier quel message est concerné. Les messages qui sont toujours dans la langue du contenu ne seront pas affichés en utilisant qqx.

Quelques parties de l'interface ajoutent  à la chaîne affichée quand vous utilisez l'astuce qqx. Par exemple l'étiquette de l'onglet qui pointe sur la page de discussion dans l'espace de noms principal est affichée en tant que, mais la chaîne se trouve actuellement dans MediaWiki:Talk.

Dans le cas où la page utilise des onglets comme par exemple la page spéciale "Preferences" vous devrez ajouter l'onglet après le paramètre, par exemple.

Format des fichiers de localisation
Tous les messages utilisés dans MediaWiki sont définis dans un fichier de messages.

Il y a deux types de fichiers de messages dans MediaWiki : JSON et PHP. Depuis avril 2014, le noyau de MediaWiki et la plupart des extensions les mieux maintenues ont migré au format JSON. Vous devez utiliser JSON pour tous les nouveaux développements. Pour plus d'information sur la migration en JSON, voir Requests for comment/Localisation format.

JSON
Depuis la fin 2013 un nouveau format de fichier de messages a été introduit : JSON. C'est le JSON à plat, familier en tant que format commun générique de stockage des données. Chacune des clés est une clé de message, et la valeur est le texte du message. En plus, la clé spéciale  est utilisée pour stocker les informations concernant la traduction telles que les auteurs de la traduction.

L'utilisation de JSON rend les fichiers de localisation plus sécurisés car ce n'est pas du code exécutable. It is also compatible with jquery.i18n, a JavaScript library developed as part of Project Milkshake, which provides MediaWiki-like frontend localisation capabilities and is used by some extensions that want to be less dependent on MediaWiki, such as VisualEditor and UniversalLanguageSelector.

Because the wider suite of internationalisation and localisation tools were called "Project Milkshake", some people call this format "banana".

Emplacement des fichiers
Dans le noyau MediaWiki, les fichiers internationalisés se trouvent dans le répertoire. Les extensions MediaWiki mettent habituellement les leurs dans un sous-répertoire. If a large number of messages exist within a project, one may want to split these into two or more topical subdirectories for maintainability. In MediaWiki context, the configuration key is used to list these subdirectories. Voici un exemple de l'extension VisualEditor pour MediaWiki :

You add new messages to the English "en" messages file  and document them in the message documentation file with the special pseudo-language code "qqq" –. Voir aussi : Ajouter de nouveaux messages.

Métadonnées
Currently the following metadata fields are used in the files:


 * authors
 * Liste JSON des auteurs des messages. For English (en) and message documentation (qqq) these are added manually when the messages file is edited. For all other languages this is inserted automatically when the message file is exported from translatewiki.net. Message documentation can be edited on translatewiki.net, and documentation editors are inserted to the qqq.json file automatically as well.


 * message-documentation
 * This is the pseudo-language code for storing the message documentation. For MediaWiki this is always qqq. (This appears in some extensions, but it's not actually processed in any way. It's not mandatory.)

Conventions
Special characters like line breaks are escaped.

Unicode characters that represent letters in different alphabets are stored as real characters and not as character codes, because these files are sometimes read by people and because this makes the files smaller ( and not  ). In any case, developers have few reasons to edit messages in any languages except English, because these are usually edited through translatewiki.net.

HTML code is not escaped either, so  and not.

L'indentation dans les fichiers JSON se fait en utilisant les caractères de tabulation.

PHP
L'ancien format du fichier de localisation est PHP. Il s'agit essentiellement d'un tableau PHP contenant tous les messages. In core MediaWiki each language resides in its own file in the languages/message directory of the MediaWiki source code. In the extensions all the languages and the message documentation (qqq) are in the same file: ExtensionName.i18n.php, usually in the main directory of the extension.

To migrate from PHP to JSON use the generateJsonI18n.php script. It will move the messages to JSON files and replace the text of the PHP file with a shim that points to the JSON files. This boilerplate code is needed for backwards compatibility with MediaWiki 1.19. It is not used in new extensions that do not require MediaWiki 1.19 compatibility.

Utiliser les messages
MediaWiki uses a central repository of messages which are referenced by keys in the code. This is different from, for example,, which just extracts the translatable strings from the source files. The key-based system makes some things easier, like refining the original texts and tracking changes to messages. The drawback is of course that the list of used messages and the list of source texts for those keys can get out of sync. In practice this isn't a big problem, and the only significant problem is that sometimes extra messages that are not used anymore still stay up for translation.

To make message keys more manageable and easy to find, also with grep, always write them completely and don't rely too much on creating them dynamically. You may concatenate parts of message keys if you feel that it gives your code better structure, but put a comment nearby with a list of the possible resulting keys.

Voir aussi les conventions de codage. Par exemple :

To use a message in JavaScript, you have to list it in the definition of your ResourceLoader module, in the  property.

The detailed use of message functions in PHP and JavaScript is on. ''' This is an important documentation page, and you should read it before you write code that uses messages. '''

Sources des messages
Le code recherche les messages système depuis les sources suivantes :
 * Espace de noms MediaWiki. Ceci permet aux wikis d’adopter ou de remplacer tous leurs messages, quand les messages standards ne conviennent pas bien ou ne sont pas souhaités.
 * MediaWiki:Message-key est le message par défaut,
 * MediaWiki:Message-key/language-code est le message à utiliser quand un utilisateur a sélectionné une autre langue que la langue par défaut du wiki.
 * A partir des fichiers de messages :
 * Le noyau MediaWiki lui-même et la plupart des extensions les plus maintenues actuellement utilisent un fichier par langue, appelé, où zyx est le code de la langue.
 * Certaines extensions plus anciennes utilisent un fichier de messages combiné contenant tous les messages dans toutes les langues, habituellement appelé.
 * ** De nombreux wikis de la Fondation Wikimedia accèdent à certains messages de l’extension, leur permettant de standardiser les messages au travers des wikis WMF sans les imposer sur chaque installation de MediaWiki.
 * ** Seules quelques extensions utilisent d’autres techniques.

Mise en cache
System messages are one of the more significant components of MediaWiki, primarily because it is used in every web request. The PHP message files are large, since they store thousands of message keys and values. Loading this file (and possibly multiple files, if the user's language is different from the content language) has a large memory and performance cost. An aggressive, layered caching system is used to reduce this performance impact.

MediaWiki has lots of caching mechanisms built in, which make the code somewhat more difficult to understand. Since 1.16 there is a new caching system, which caches messages either in cdb files or in the database. Customised messages are cached in the filesystem and in memcached (or alternative), depending on the configuration.

The table below gives an overview of the settings involved:

In MediaWiki 1.27.0 and 1.27.1, the autodetection was changed to favor the file backend. In case  (the default), the file backend is used with the path from. If this value is not set (which is the default), a temporary directory determined by the operating system is used. If a temporary directory cannot be detected, the database backend is used as a fallback. This was reverted from 1.27.2 and 1.28.0 because of conflict of files on shared hosts and security issues (see T127127 and T161453).

Trace de fonction
To better visually depict the layers of caching, here is a function backtrace of what methods are called when retrieving a message. See the below sections for an explanation of each layer.



Cache des messages
The  class is the top level of caching for messages. It is called from the Message class and returns the final raw contents of a message. Ce niveau gère la logique suivante :

Resolving the remainder of the language fallback sequence
 * Checking for message overrides in the database
 * Caching over-ridden messages in, or whatever is set to

Le dernier point est important. Language fallbacks allow MediaWiki to fall back on another language if the original does not have a message being asked for. As mentioned in the next section, most of the language fallback resolution occurs at a lower level. However, only the  layer checks the database for overridden messages. Thus integrating overridden messages from the database into the fallback chain is done here. If not using the database, this entire layer can be disabled.

Cache d'internationalisation
Voir LocalisationCache.php

LCStore
The  class is merely a back-end implementation used by the LocalisationCache class for actually caching and retrieving messages. Like the  class, which is used for general caching in MediaWiki, there are a number of different cache types (configured using $wgLocalisationCacheConf): "accel" - Uses APC or another opcode cache to store the data
 * "db" (default) - Caches messages in the database
 * "file" (default if  is set) - Uses CDB to cache messages in a local file

The "file" option is used by the Wikimedia Foundation, and is recommended because it is faster than going to the database and more reliable than the APC cache, especially since APC is incompatible with PHP versions 5.5 or later.

Choisir la clé du message
Voir aussi :

La clé du message doit être globalement unique. Cela comprend le noyau de MediaWiki avec toutes les extensions et les habillages.

Stick to lower case letters, numbers, and dashes in message names; most other characters are between less practical or not working at all. Per MediaWiki convention, first character is case-insensitive and other chars are case-sensitive.

Please follow global or local conventions for naming. For extensions, use a standard prefix, preferably the extension name in lower case, followed by a hyphen ("-"). Exceptions are:


 * Messages used by the API. These must begin with,  ,  . Placez le préfixe de l'extension à la suite de ce préfixe. ( Note that these messages should be in a separate file, usually under includes/i18/api. )
 * Log-related messages. These must begin with,  ,.
 * Droits utilisateur. The key for the name of the right as displayed on Special:ListGroupRights must begin with . The name of the action that completes the sentence "" must begin with.
 * Les balises de révision doivent commencer par.
 * Les titres des pages spéciales doivent commencer par.

Autres éléments à prendre en compte pour créer des messages
In particular, API messages that are only seen by developers and not by most end users are usually in a separate file, such as. If an extensions has a lot of messages, you may create subdirectories under. All the message directories, including the default, must be listed in the   section in   or in the variable.
 * 1) Make sure that you are using suitable handling for the message (parsing,  -replacement, escaping for HTML, etc.)
 * 1) If your message is part of core, it should usually be added to , although some components, such as Installer, EXIF tags, and ApiHelp have their own message files.
 * 1) If your message is in an extension add it to the   file or the   file in the appropriate subdirectory.
 * 1) Arrêtez-vous et analysez les mots du message. Est-ce suffisamment clair ? Can it be misunderstood? Ask for comments from other developers or localisers if possible. Suivez les directives de traduction.
 * 2) Ajoutez la documentation à   dans le même répertoire.

Messages à ne pas traduire
They are messages that should not need translation, because they reference only other messages or language-neutral features, e.g. a message of " ".
 * 1) Ignored messages are those which should exist only in the English messages file.
 * 1) Optional messages may be translated only if changed in the target language.

To flag such messages:


 * use the template in the  message documentation, that is respectively
 * or
 * tell the extension used on  what to do with the messages by submitting a patch listing them as appropriate (see also ):
 * for core, in add the message keys
 * under  or
 * under ;
 * for extensions, in add a line under the extension's name like
 * or
 * or

Supprimer des messages existants
Remove it from  and. Don't bother with other languages. Updates from will handle those automatically.

In addition, check whether the message appears anywhere in translatewiki configuration, for example in the list of optional or most used messages (a simple git grep should be enough). Remove it from these lists if needed.

Modifier des messages existants
This also includes changes in message handling (parsing, escaping, parameters, etc.). Improving the phrasing of a message without technical changes is usually not a reason for changing a key. At translatewiki.net, the translations will be marked as outdated so that they can be targeted by translators. Changing a message key does not require talking to the i18n team or filing a support request. However, if you have special circumstances or questions, ask in or in the support page at. If needed, the translatewiki.net team will take care of updating the translations, marking them as outdated, cleaning up the file or renaming keys where possible. This also applies when you're only changing things like HTML tags which you could change in other languages without speaking those languages. Most of these actions will take place in translatewiki.net and will reach Git with about one day of delay.
 * 1) Consider updating the  message documentation.
 * 1) Change the message key if old translations are not suitable for the new meaning.
 * 1) If the extension is supported by, please only change the English source message and/or key, and the accompanying entry in.

Documentation des messages
There is a pseudo-language code  for message documentation. It is one of the ISO 639 codes reserved for private use. There, we do not keep translations of each message, but collect English sentences about each message: telling us where it is used, giving hints about how to translate it, and enumerating and describing its parameters, link to related messages, and so on. In translatewiki.net, these hints are shown to translators when they edit messages.

Programmers must document each and every message. Message documentation is an essential resource – not just for translators, but for all the maintainers of the module. Whenever a message is added to the software, a corresponding  entry must be added as well; revisions which don't do so are marked " " until the documentation is added.

Documentation in  files should be edited directly only when adding new messages or when changing an existing English message in a way that requires a documentation change, for example adding or removing parameters. In other cases, documentation should usually be edited in translatewiki. Each documentation string is accessible at https://translatewiki.net/wiki/MediaWiki: message-key /qqq, as if it were a translation. These edits will be exported to the source repositories along with the translations.

Useful information that should be in the documentation includes:


 * 1) Message handling (parsing, escaping, plain text).
 * 1) Type of parameters with example values.
 * 1) Where the message is used (pages, locations in the user interface).
 * 1) How the message is used where it is used (a page title, button text, etc.).
 * 1) What other messages are used together with this message, or which other messages this message refers to.
 * 1) Anything else that could be understood when the message is seen on the context, but not when the message is displayed alone (which is the case when it is being translated).
 * 1) If applicable, notes about grammar. For example, "open" in English can be both a verb and an adjective. In many other languages the words are different and it's impossible to guess how to translate them without documentation.
 * 2) Adjectives that describe things, such as "disabled", "open" or "blocked", must always say what are they describing. In many languages adjectives must have the gender of the noun that they describe. It may also happen that different kinds of things need different adjectives.
 * 1) If the message has special properties, for example, if it is a page name, or if it should not be a direct translation, but adapted to the culture or the project.
 * 1) Whether the message appears near other message, for example in a list or a menu. The wording or the grammatical features of the words should probably be similar to the messages nearby. Also, items in a list may have to be properly related to the heading of the list.
 * 1) Parts of the message that must not be translated, such as generic namespace names, URLs or tags.
 * 1) Explanations of potentially unclear words, for example abbreviations, like "CTA", or specific jargon, like "template", "suppress" or "stub". (Note that it's best to avoid such words in the first place!)
 * 2) Screenshots are very helpful. Don't crop – an image of the full screen in which the message appears gives complete context and can be reused in several messages.

A few other hints:


 * Remember that very, very often translators translate the messages without actually using the software.
 * Most usually, translators do not have any context information, neither of your module, nor of other messages in it.
 * A rephrased message alone is useless in most circumstances.
 * Don't use designers' jargon like "nav" or "comps".
 * Consider writing a glossary of the technical terms that are used in your module. If you do it, link to it from the messages' documentation.

You can link to other messages by using. Please do this if parts of the messages come from other messages (if this cannot be avoided), or if some messages are shown together or in same context.

translatewiki.net provides some default templates for documentation:


 * - for  messages
 * - for  messages
 * - for messages around user groups (, ,  ,   and  )
 * - for  messages

Have a look at the template pages for more information.

Conseils pour internationaliser
Besides documentation, translators ask developers to consider some hints so as to make their work easier and more efficient and to allow an actual and good localisation for all languages. Even if only adding or editing messages in English, one should be aware of the needs of all languages. Each message is translated into more than 300 languages and this should be done in the best possible way. Correct implementation of these hints will very often help you write better messages in English, too.

Localisation lists the main places where you can find the assistance of experienced and knowledgeable people regarding i18n.

Use Message parameters and switches properly
That's a prerequisite of a correct wording for your messages.

Avoid message re-use
The translators discourage message re-use. This may seem counter-intuitive, because copying and duplicating code is usually a bad practice, but in system messages it is often needed. Although two concepts can be expressed with the same word in English, this doesn't necessarily mean they can be expressed with the same word in every language. "OK" is a good example: in English this is used for a generic button label, but in some languages they prefer to use a button label related to the operation which will be performed by the button. Another example is practically any adjective: a word like "multiple" changes according to gender in many languages, so you cannot reuse it to describe several different things, and you must create several separate messages.

If you are adding multiple identical messages, please add message documentation to describe the differences in their contexts. Don't worry about the extra work for translators. Translation memory helps a lot in these while keeping the flexibility to have different translations if needed.

Eviter les messages fragmentés ou sous forme de 'patchwork'
Languages have varying word orders, and complex grammatical and syntactic rules. It's very hard to translate "lego" messages, that is messages formed by multiple pieces of text, possibly with some indirection (also called "string concatenation").

It is better to make every message a complete phrase. Several sentences can usually be combined much more easily into a text block, if needed. When you want to combine several strings in one message, pass them in as parameters, as translators can order them correctly for their language when translating.

Messages se référençant mutuellement
An exception from the rule may be messages referring to one another: 'Enter the original author's name in the field labelled " " and click "  " when done'. This makes the message consistent when a software developer or wiki operator alters the messages "name" or "proceed" later. Without the int-trick, developers and operators would have to be aware of all related messages needing adjustment, when they alter one.

N'utilisez pas les termes et les modèles spécifiques à un projet particulier
MediaWiki is used by very diverse people, within the Wikimedia movement and outside of it. Even though it was originally built for an encyclopedia, it is now used for various kinds of content. Therefore, use general terms. For example, avoid terms like "article", and use "page" instead, unless you are absolutely sure that the feature you are developing will only be used on a site where pages are called "articles". Don't use "village pump", which is the name of an English Wikipedia community page, and use a generic term, such as "community discussion page", instead.

Don't assume that a certain template exists on all wikis. Templates are local to wikis. This applies to both the source messages and to their translations. If messages use templates, they will only work if a template is created on each wiki where the feature is deployed. It's best to avoid using templates in messages completely. If you really have to use them, you must document this clearly in the message documentation and in the extension installation instructions.

Séparer le temps et les dates dans les phrases
Some languages have to insert something between a date and a time which grammatically depends on other words in a sentence. Thus, they will not be able to use date/time combined. Others may find the combination convenient, thus it is usually the best choice to supply three parameter values (date/time, date, time) in such cases, and in each translation leave either the first one or last two unused as needed.

Évitez dans les messages
has several disadvantages. It can be anything (acronym, word, short phrase, etc.) and, depending on language, may need the use of  on each occurrence. No matter what, each message having  will need review in most wiki languages for each new wiki on which your code is installed. In the majority of cases, when there is not a general  configuration for a language, wiki operators will have to add or amend PHP code so as to get   for   working. This requires both more skills, and more understanding, than otherwise. It is more convenient to have generic references like "this wiki". This does not keep installations from locally altering these messages to use, but at least they don't have to, and they can postpone message adaption until the wiki is already running and used.

Eviter les références au rendu visuel et aux positions
What is rendered where depends on skins. Most often screen layouts of languages written from left-to-right are mirrored compared to those used for languages written from right-to-left, but not always, and for some languages and wikis, not entirely. Handheld devices, narrow windows, and so on may show blocks underneath each other, that would appear side-by-side on larger displays. Since site- and user-written JavaScript scripts and gadgets can, and do, hide parts, or move things around in unpredictable ways, there is no reliable way of knowing the actual layout.

It is wrong to tie layout information to content languages, since the user interface language may not be the page's content language, and layout may be a mixture of the two depending on circumstances. Non-visual user agents like acoustic screen readers and other auxiliary devices do not even have a concept of visual layout. Thus, you should not refer to visual layout positions in the majority of cases, though semantic layout terms may still be used ("previous steps in the form", etc.).

MediaWiki does not support showing different messages or message fragments based on the current directionality of the interface (see T30997).

The upcoming browser and MediaWiki support for East and North Asian top-down writing will make screen layouts even more unpredictable, with at least eight possible layouts (left/right starting position, top/bottom starting position, and which happens first).

Eviter les références aux couleurs de l'écran
The colour in which something is rendered depends on many factors, including skins, site- and user-written JavaScript scripts and gadgets, and local user agent over-rides for reasons of accessibility or technological limitations. Non-visual user agents like acoustic screen readers and other auxiliary devices do not even have a concept of colour. Thus, you should not refer to screen colours. (You should also not rely on colour alone as a mechanism for informing the user of state, for the same reason.)

Avoir les éléments des messages avant et après chaque champ de saisie

 *  This is a suggested guideline, has not become standard in MediaWiki development 

While English allows efficient use of prompting in the form item–colon–space–input-field, many other languages don't. Even in English, you often want to use "Distance: ___ metres" rather than "Distance (in metres): ___". Leaving elements aside, you should think of each and every input field following the "Distance: ___ metres" pattern. So:


 * give it two messages, even if the 2nd one is empty in English and some other languages, or
 * allow the placement of inputs via  parameters.

Evitez le marquage HTML non traduit dans les messages
HTML markup not requiring translation, such as enclosing s, rulers above or below, and similar, should usually not be part of messages. They unnecessarily burden translators, increase message file size, and pose the risk to accidentally being altered or skipped in the translation process. In general, avoid raw HTML in messages if you can.

Les messages sont souvent plus longs que vous le pensez !
Skimming foreign language message files, you almost never find messages shorter than Chinese ones, rarely shorter than English ones, and usually much longer than English ones.

Especially in forms, in front of input fields, English messages tend to be terse, and short. That is often not kept in translations. Languages may lack the technical vocabulary present in English, and may require multiple words or even complete sentences to explain some concepts. For example, the brief English message "TSV file:" may have to be translated in a language as literally: " Please type a name here which denotes a collection of computer data that is comprised of a sequentially organised series of typewritten lines which themselves are organised as a series of informational fields each, where said fields of information are fenced, and the fences between them are single signs of the kind that slips a typewriter carriage forward to the next predefined position each. Here we go: _____ (thank you) " This is, admittedly, an extreme example, but you get the trait. Imagine this sentence in a column in a form where each word occupies a line of its own, and the input field is vertically centered in the next column. :-(

Eviter d'utiliser des mots très proches, similaires, ou identiques pour désigner des choses ou des concepts différents
For example, pages may have older revisions (of a specific date, time, and edit), comprising past versions of said page. The words revision, and version can be used interchangeably. A problem arises, when versioned pages are revised, and the revision, i.e. the process of revising them, is being mentioned, too. This may not pose a serious problem when the two synonyms of "revision" have different translations. Do not rely on that, however. It is better to avoid the use of "revision" aka "version" altogether, then, so as to avoid it being misinterpreted.

Les mots de base peuvent avoir des connotations imprévues, ou ne pas exister du tout
There are some words that are hard to translate because of their very specific use in MediaWiki. Some may not be translated at all. For example, there is no word "user" relating to "someone who uses something" in several languages. Similarly, in Kölsch the English words "namespace" and "apartment" translate the same word. Also, in Kölsch, they say "corroborator and participant" in one word since any reference to "use" would too strongly imply "abuse". The term "wiki farm" is translated as "stable full of wikis", since a single-crop farm would be a contradiction in terms in the language, and not understood, etc..

Attendez-vous à des mots non traduits

 *  This is a suggested guideline, has not yet become standard in MediaWiki development 

It is not uncommon that proper names, tag names, etc. and computerese in English are not translated, and instead taken as loan-words, or foreign words. In the latter case, some particularly-fastidious translators may mark such words as belonging to another language with HTML markup, such as.

You may want to consider ensuring that your message output handler passes such markup along unchanged, despite the obvious security risks.

Permettre le marquage explicatif en ligne

 *  This is a suggested guideline, has not yet become standard in MediaWiki development 

Sometimes there are abbreviations, technical terms, or generally ambiguous words in target languages that may not be immediately understood by newcomers, but are obvious to experienced computer users. To avoid screen clutter of lengthy explanations without leaving newcomers stranded, translators may choose to add explanations as annotations, shown by browsers when you move the mouse over them.

For example, the MediaWiki core message  about image rotation, which in English is simply " ", in Moroccan Arabic is translated as:



giving:


 * mḍwwer 90° ĜĜS

explaining the abbreviation for "counter clockwise" when needed.

You may want to consider ensuring that your message output handler passes such markup along unchanged, even if the original message does not use them.

Utiliser les balises, , et à bon escient
When talking about technical parameters, values, or keyboard inputs, mark them appropriately as such using the HTML tags, , or. Thus they are typographically set off form the normal text. That clarifies their sense to readers, avoiding confusion, errors and mis-representations. Ensure that your message handler allows such markup.

Symboles, deux points, crochets, etc. faisant partie des messages
Many symbols are localisable, too. Some scripts have other kinds of brackets than the Latin script has. A colon may not be appropriate after a label or input prompt in some languages. Having those symbols included in messages helps to make better and less Anglo-centric translations, and also reduces code clutter.

For example, there are different quotation mark conventions used in «Norwegian», »Swedish», »Danish«, „German“, and 「Japanese」.

If you need to wrap some text in localized parentheses, brackets, or quotation marks, you can use the   or    or    messages like so:

N'espérez pas que les symboles et la ponctuation survivent à la traduction
Languages written from right to left (as opposed to English) usually swap arrow symbols being presented with "next" and "previous" links, and their placement relative to a message text may, or may not, be inverted as well. Ellipsis may be translated to "etc.", or to words. Question marks, exclamation marks, colons will be placed other than at the end of a sentence, not at all, or twice. As a consequence, always include all of those in the text of your messages, and never try to insert them programmatically.

Utiliser les arrêts complets
Do terminate normal sentences with full stops. This is often the only indicator for a translator to know that they are not headlines or list items, which may need to be translated differently.

Wikicode des liens
Link anchors can be put into messages in several technical ways:

…  …, …   …, or
 * 1) via wikitext:
 * 1) via wikitext:
 * 1) the anchor text is a message in the MediaWiki namespace. Avoid it!

The latter is often hard or impossible to handle for translators, avoid fragmented or 'patchwork' messages here, too. Make sure that " " does not contain spaces.

Utiliser des ancres ayant des noms significatifs
Take care with your wording. Link anchors play an important role in search engine assessment of pages – both the words linked, and the target anchor. Make sure that the anchor describes the target page well. Always avoid commonplace and generic words. For example, "Click here" is an absolute no-go, since target pages are almost never about "click here". Do not put that in sentences around links either, because "here" was not the place to click. A la place, utilisez des mots représentant des actions précises pour dire ce qu'obtiendra l'utilisateur en ouvrant le lien, comme « Vous pouvez téléverser un fichier si vous le souhaitez. »

See also Help users predict where they are going, and mystery meat navigation, and The main reasons why we shouldn't use click here as link text.

Eviter le jargon et l'argot
Avoid developer and power user jargon in messages. Try to use a simple language whenever possible. Avoid saying "success", "successfully", "fail", "error occurred while", etc., when you want to notify the user that something happened or didn't happen. This comes from developers' perspective of seeing everything as true or false, but users usually just want to know what actually happened or didn't, and what they should do about it (if at all). So:

"File renaming failed" -> "There is a file with this name already. Please choose a different name."
 * "The file was successfully renamed" -> "The file was renamed"

Faites attention aux caractères espace et aux retours à la ligne
MediaWiki's localised messages usually get edited within the wiki, either by wiki operations on live wikis, or by the translators on translatewiki.net. You should be aware of how whitespace, especially at the beginning or end of your message, will affect editors:


 * Spaces and line breaks (new lines) at the end of the message are always automatically removed by the wikitext editor. Your message must not end with a space or line break, as it will be lost when it's edited on the wiki.
 * Spaces and line breaks at the beginning are not automatically removed, but they are likely to be removed by accident during editing, and should be avoided.

Start and end your message with active text; if you need a newline or paragraph break around it, your surrounding code should deal with adding it to the returned text.

There are some messages which require a space at the end, such as 'word-separator' (which consists of just a space character in most languages). To support such use cases, the following HTML entities are allowed in messages and transformed to the actual characters, even if the message otherwise doesn't allow wikitext or HTML formatting:


 * – space
 * or  – non-breaking space
 * – soft hyphen

On a related note, any other syntax elements affected by pre-save transforms also must not be used in messages, as they will be transformed when the message is edited on the wiki.

Utiliser la capitalisation standard
Capitalisation gives hints to translators as to what they are translating, such as single words, list or menu items, phrases, or full sentences. Correct (standard) capitalisation may also play a role in search engines' assessment of your pages. MediaWiki uses sentence case (The quick brown fox jumps over the lazy dog) in interface messages.

Always remember that many writing systems don't have capital letters at all, and some of those that do have them, use them differently from English. Therefore, don't use ALL-CAPS for emphasis. Use CSS, or HTML or  per below:

Emphase
In normal text, emphasis like boldface or italics and similar should be part of message texts. Local conventions on emphasis often vary, especially some Asian scripts have their own. Translators must be able to adjust emphasis to their target languages and areas. Try to use "" and "" in your user interface to allow mark-up on a per language or per script basis.

In modern screen layouts of English and European styles, emphasis becomes less used. Do convey it in your still, as it may give valuable hints as to how to translate. Emphasis can and should be used in other cultural contexts as appropriate, provided that translators know about it.
