If you have a simple task that you need to perform lots of times (an example might be to add a to all pages in a category with 1000 pages), then this is a task better suited to a bot than a human.Considerations before creating a bot It is often far simpler to request a bot job from an existing bot. If you have only periodic requests or are uncomfortable with programming, this is usually the best solution. These requests can be made at. In addition, there are a number of tools available to anyone. Most of these take the form of enhanced web browsers with Mediawiki-specific functionality. The most popular of these is (AWB), a browser specifically designed to assist with editing on Wikipedia and other Wikimedia projects. A mostly complete list of tools can be found at.

Tools, such as AWB, can often be operated with little or no understanding of programming.If you decide you need a bot of your own due to the frequency or novelty of your requirements, you don't need to write one from scratch. There are already a and many of these bots publish their source code, which can sometimes be reused with little additional development time. There are also a number of standard bot frameworks available.

Modifying an existing bot or using a framework greatly speeds development time. Also, because these code bases are in common usage and are maintained community projects, it is far easier to get bots based on these frameworks approved for use.

The most popular and common of these frameworks is (PWB), a bot framework written in. It is thoroughly documented and tested and many standardized Pywikibot scripts (bot instructions) are already available. Other examples of bot frameworks can be found. For some of these bot frameworks, such as PWB, a general familiarity with scripts is all that is necessary to run the bot successfully (it is important to update these frameworks regularly).Writing a new bot requires significant programming ability. A completely new bot must undergo substantial testing before it will be approved for regular operation. To write a successful bot, planning is crucial. The following considerations are important:.

Will the bot be manually assisted or fully automated?. Will you create the bot alone, or with the help of other programmers?. Will the bot's requests, edits, or other actions be logged? If so, will the logs be stored on local media, or on wiki pages?. Will the bot run inside a web browser (for example, written in Javascript), or will it be a standalone program?. If the bot is a standalone program, will it run on your local computer, or on a remote server such as the?. If the bot runs on a remote server, will other editors be able to operate the bot or start it running?How does a Wikipedia bot work?

Overview of operation. Just like a human editor, a Wikipedia bot reads Wikipedia pages, and makes changes where it thinks changes need to be made. The difference is that, although bots are faster and less prone to fatigue than humans, they are nowhere near as bright as we are.

Bots are good at repetitive tasks that have easily defined patterns, where few decisions have to be made.In the most typical case, a bot logs in to its own account and requests pages from Wikipedia in much the same way as a browser does – although it does not display the page on screen, but works on it in memory – and then programmatically examines the page code to see if any changes need to be made. It then makes and submits whatever edits it was designed to do, again in much the same way a browser would.Because bots access pages the same way people do, bots can experience the same kind of difficulties that human users do. They can get caught in edit conflicts, have page timeouts, or run across other unexpected complications while requesting pages or making edits. Because the volume of work done by a bot is larger than that done by a live person, the bot is more likely to encounter these issues. Thus, it is important to consider these situations when writing a bot.APIs for bots In order to make changes to Wikipedia pages, a bot necessarily has to retrieve pages from Wikipedia and send edits back. There are several (APIs) available for that purpose.

This library was specifically written to permit automated processes such as bots to make queries and post changes. Data is returned in format (see for more details).Status: Built-in feature of MediaWiki, available on all Wikimedia servers.

Other non-Wikimedia wikis may disable or restrict write access. There is also an for those wanting to test api.php's features. can be used to obtain bulk export of page content in XML form. See for arguments;Status: Built-in feature of MediaWiki, available on all Wikimedia servers. Raw (Wikitext) page processing: sending a action=raw or a action=raw&templates=expand GET request to index.php will give the unprocessed wikitext source code of a page. An API query with action=query&prop=revisions&rvprop=content or action=query&prop=revisions&rvprop=content&rvexpandtemplates=1 is roughly equivalent, and allows for retrieving additional information.Status: Built-in feature of MediaWiki, available on all Wikimedia servers.Some Wikipedia web servers are configured to grant requests for compressed content. This can be done by including a line 'Accept-Encoding: gzip' in the HTTP request header; if the HTTP reply header contains 'Content-Encoding: gzip', the document is in gzip form, otherwise, it is in the regular uncompressed form.

Note that this is specific to the web server and not to the MediaWiki software. Other sites employing MediaWiki may not have this feature. If you are using an existing bot framework, it should handle low-level operations like this.Logging in Approved bots need to be logged in to make edits. Although a bot can make read requests without logging in, bots that have completed testing should log in for all activities. Bots logged in from an account with the bot flag can obtain more results per query from the Mediawiki API (api.php). Most bot frameworks should handle login and cookies automatically, but if you are not using an existing framework, you will need to follow these steps.For security, login data must be passed using the method.

Because parameters of requests are easily visible in URL, logins via GET are disabled.To log a bot in using the, 2 requests are needed:Request 1 – this is a GET request to obtain a login token. URL:Request 2 – this is a POST to complete the login. URL:. POST parameters:.

lgname=BOTUSERNAME. lgpassword=BOTPASSWORD.

lgtoken=TOKENwhere TOKEN is the token from the previous result. The HTTP cookies from the previous request must also be passed with the second request.A successful login attempt will result in the Wikimedia server setting several. The bot must save these cookies and send them back every time it makes a request (this is particularly crucial for editing).

On the English Wikipedia, the following cookies should be used: enwikiUserID, enwikiToken, and enwikiUserName. The enwikisession cookie is required to actually send an edit or commit some change, otherwise the error message will be returned.Main-account login via 'action=login' is deprecated and may stop working without warning. To continue login with 'action=login', see.Editing; edit tokens Wikipedia uses a system of for making edits to Wikipedia pages, as well as other operations that modify existing content such as rollback. The token looks like a long hexadecimal number followed by '+', for example:d41d8cd98f00b2ecf8427e+The role of edit tokens is to prevent 'edit hijacking', where users are tricked into making an edit by clicking a single link.The editing process involves two HTTP requests. First, a request for an edit token must be made.

Then, a second HTTP request must be made that sends the new content of the page along with the edit token just obtained. It is not possible to make an edit in a single HTTP request. An edit token remains the same for the duration of a logged-in session, so the edit token needs to be retrieved only once and can be used for all subsequent edits.To obtain an edit token, follow these steps:. MediaWiki API (api.php). Make a request with the following parameters (see ). action=query. prop=info.

titles=PAGENAME. intoken=editThe token will be returned in the edittoken attribute of the response.If the edit token the bot receives does not have the hexadecimal string ( i.e., the edit token is just '+') then the bot most likely is not logged in.

This might be due to a number of factors: failure in authentication with the server, a dropped connection, a timeout of some sort, or an error in storing or returning the correct cookies. If it is not because of a programming error, just log in again to refresh the login cookies. The bots may use to make sure that they are logged in.Edit conflicts Edit conflicts occur when multiple, overlapping edit attempts are made on the same page. Almost every bot will eventually get caught in an edit conflict of one sort or another, and should include some mechanism to test for and accommodate these issues.Bots that use the Mediawiki API (api.php) should retrieve the edit token, along with the starttimestamp and the last revision 'base' timestamp, before loading the page text in preparation for the edit; prop=info revisions can be used to retrieve both the token and page contents in one query ( ). When submitting the edit, set the starttimestamp and basetimestamp attributes, and check the server responses for indications of errors. For more details, see.Generally speaking, if an edit fails to complete the bot should check the page again before trying to make a new edit, to make sure the edit is still appropriate. Further, if a bot rechecks a page to resubmit a change, it should be careful to avoid any behavior that could lead to an infinite loop and any behavior that could even resemble.Overview of the process of developing a bot Actually, coding or writing a bot is only one part of developing a bot.

You should generally follow the development cycle below to ensure that your bot follows. Failure to comply with the policy may lead to your bot failing to be approved or being blocked from editing Wikipedia.

Overview of Wikipedia bot development cycle Idea. The first task in creating a Wikipedia bot is extracting the requirements or coming up with an idea. If you don't have an idea of what to write a bot for, you could pick up ideas at.

Make sure an existing bot isn't already doing what you think your bot should do. To see what tasks are already being performed by a bot, see.Specification. is the task of precisely describing the software to be written, possibly in a rigorous way. You should come up with a detailed proposal of what you want it to do. Try to discuss this proposal with some editors and refine it based on feedback. Even a great idea can be made better by incorporating ideas from other editors.

Best Bot Software

In the most basic form, your specified bot must meet the following criteria:. The bot is harmless (it must not make edits that could be considered disruptive to the smooth running of the encyclopedia). The bot is useful (it provides a useful service more effectively than a human editor could).

The bot does not waste server resources.Software architecture. Think about how you might create it and which programming language(s) and tools you would use. Is concerned with making sure the software system will meet the requirements of the product as well as ensuring that future requirements can be addressed. Certain programming languages are better suited to some tasks than others, for more details see.Implementation (or coding) involves turning design and planning into code. It may be the most obvious part of the software engineering job, but it is not necessarily the largest portion. In the implementation stage you should:. Create an account for your bot.

Click when logged in to create the account, linking it to yours. (If you do not create the bot account while logged in, it is likely to be blocked as a possible or unauthorised bot until you verify ownership). Create a user page for your bot. Your bot's edits must not be made under your own account. Your bot will need its own account with its own username and password.

Add the same information to the user page of the bot. It would be a good idea to add a link to the approval page (whether approved or not) for each function.Testing A good way of testing your bot as you are developing is to have it show the changes (if any) it would have made to a page, rather than actually editing the live wiki. Some bot frameworks (such as ) have pre-coded methods for showing diffs. During the, the bot will most likely be given a trial period (usually with a restriction on the number of edits or days it is to run for) during which it may actually edit to enable fine-tuning and iron out any bugs. At the end of the trial period, if everything went according to plan, the bot should get approval for full-scale operation.Documentation An important (and often overlooked) task is the internal design of your bot for the purpose of future maintenance and enhancement. This is especially important if you are going to allow clones of your bot.

Ideally, you should post the source code of your bot on its userpage or in a revision control system (see ) if you want others to be able to run clones of it. This code should be well documented (usually using comments) for ease of use.Queries/Complaints You should be ready to respond to queries about or objections to your bot on your user talk page, especially if it is operating in a potentially sensitive area, such as.Maintenance and enhancing your bot to cope with newly discovered bugs or new requirements can take far more time than the initial development of the software. To ease maintenance, document your code from the beginning.Major functionality changes of approved bots must be.General guidelines for running a bot In addition to the official bot policy, which covers the main points to consider when developing your bot, there are a number of more general advisory points to consider when developing your bot.Bot best practices. Set a custom header for your bot, per the. If you don't, your bot may encounter errors and may end up blocked by the technical staff at the server level.

Use the with a maximum lag of 5 seconds. This will enable the bot to run quickly when server load is low, and throttle the bot when server load is high.

If writing a bot in a framework that does not support maxlag, limit the total requests (read and write requests together) to no more than 10/minute. Use the whenever possible, and set the query limits to the largest values that the server permits, to minimize the total number of requests that must be made. Edit (write) requests are more expensive in server time than read requests. Be edit-light and design your code to keep edits to a minimum. Try to consolidate edits. One single large edit is better than 10 smaller ones.

Enable and in your HTTP client library, if possible. Do not make multi-threaded requests. Wait for one server request to complete before beginning another. Back off upon receiving errors from the server. Errors such as squid timeouts are often an indication of heavy server load. Use. Make use of, an extension explicitly designed for bots to check certain conditions, which is enabled on Wikipedia.

Test your code thoroughly before making large automated runs. Individually examine all edits on trial runs to verify they are perfect.Common bot features you should consider implementing Manual assistance If your bot is doing anything that requires judgment or evaluation of context (e.g., correcting spelling) then you should consider making your bot manually-assisted, which means that a human verifies all edits before they are saved. This significantly reduces the bot's speed, but it also significantly reduces errors.Disabling the bot It should be easy to quickly disable your bot. If your bot goes bad, it is your responsibility to clean up after it! You could have the bot refuse to run if a message has been left on its talk page, on the assumption that the message may be a complaint against its activities; this can be checked using the API meta=userinfo query ( ).

Or you could have a page that will turn the bot off when changed; this can be checked by loading the page contents before each edit.Signature Just like a human, if your bot makes edits to a talk page on Wikipedia, it should sign its post with four tildes. Signatures belong only on talk namespaces with the exception of project pages used for discussion (e.g., ).Bot Flag A bot's edits will be visible at, unless the edits are set to indicate a bot. Once the bot has been approved and given its bot flag permission, one can add the 'bot-True' to the API call - see in order to hide the bot's edits in.

In Python, using either mwclient or wikitools, then adding Bot=True to the edit/save command will set the edit as a bot edit - e.g. PageObject.edit(text=pagetext, bot=True, summary=pagesummary).Open-source bots Many bot operators choose to make their code open source, and occasionally it may be required before approval for particularly complex bots.

Making your code open source has several advantages:. It allows others to review your code for potential bugs. As with prose, it is often difficult for the author of code to adequately review it. Others can use your code to build their own bots. A user new to bot writing may be able to use your code as an example or a template for their own bots.

It encourages, rather than. If you abandon the project, it allows other users to run your bot tasks without having to write new code.Open-source code, while rarely required, is typically encouraged in keeping with the open and transparent nature of Wikipedia.Before sharing code, make sure that sensitive information such as passwords is separated into a file that isn't made public.There are many options available for users wishing to make their code open. Hosting the code in a subpage of the bot's userspace can be a hassle to maintain if not automated and results in the code being multi-licensed under Wikipedia's licensing terms in addition to any other terms you may specify. A better solution is to use a such as,.

Wikipedia has articles comparing the different and, many of which have no cost.Programming languages and libraries. See also: andBots can be written in almost any programming language. The choice of a language depends on the experience and preferences of the bot writer, and on the availability of libraries relevant to bot development. The following list includes some languages commonly used for bots:Awk is an easy language for bots small and large, including OAuth.

Framework and libraries:. Example bots in the GitHub account of atPerl If located on a webserver, you can start your program running and interface with your program while it is running via the from your browser.

If your internet service provider provides you with webspace, the chances are good that you have access to a perl build on the webserver from which you can run your Perl programs.Libraries:. – A fairly complete MediaWiki bot framework written in Perl.

Provides a higher level of abstraction than MediaWiki::API. Plugins provide administrator and steward functionality.PHP can also be used for programming bots. MediaWiki developers are already familiar with PHP, since that is the language MediaWiki and its extensions are written in. PHP is an especially good choice if you wish to provide a webform-based interface to your bot.

For example, suppose you wanted to create a bot for renaming categories. You could create an HTML form into which you will type the current and desired names of a category. When the form is submitted, your bot could read these inputs, then edit all the articles in the current category and move them to the desired category. (Obviously, any bot with a form interface would need to be secured somehow from random web surfers.)The table may provide some insight into the capabilities of the major bot frameworks.Current PHP Bot frameworksKey peopleNamePHP Versionlast updateUses APIAdmin functionsPluginsRepositoryNotes, and5.2.12017YesYesYesYesLarge framework, currently undergoing rewrite.
