Extension:Replace Text/tr

Replace Text, hizmetlilerin vikinin içerik sayfaları hem metni hem de başlıkları üzerinde küresel bir dize bul ve değiştir yapmasına olanak tanıyan özel bir sayfa ve bir komut satırı betiği sağlayan bir MediaWiki uzantısıdır.

Kullanım
Replace Text, genel aramayı ve değiştirmeyi işleyen "Special:ReplaceText" (veya başka bir dildeki karşılığı) özel bir sayfayı tanımlar; aynı zamanda komut satırından da aynı şeyi yapan bir betik, replaceAll.php ile tanımlar. Bu belgelendirme önce özel sayfayı, ardından komut satırı betiğini kapsayacaktır.

Special:ReplaceText sayfası, başlangıçta bir hizmetlinin ara ve değiştir ayrıntılarını doldurması için bir form görüntüler: hizmetli, bir arama dizesi ve onun yerine aranacak ad alanları kümesini girer ve sayfadaki içerikler, sayfa başlıkları veya her ikisi metnin değiştirilip değiştirilmeyeceğini seçer. İsteğe bağlı olarak, hizmetli ayrıca iki ek filtre ekleyebilir: tüm sayfaların ait olması gereken bir kategorinin adı ve tüm sayfa adlarının başlaması gereken bir önektir. Bu form gönderildiğinde, onlara ya o arama dizesini içeren tüm sayfaların bir listesi ya da başlıkları arama dizesini içeren tüm sayfaların bir listesi ya da her ikisi de gösterilir. Her sayfa adının yanında, değiştirilmesini istemedikleri sayfaların seçimini kaldırabilmeleri için her biri için bir onay kutusu bulunur. Kullanıcı daha sonra gerçek değiştirmeyi yapmak için "Değiştir" düğmesine basabilir. Metin değişikliği yapıldığında, doğrudan geri alınamaz; yine de yeni dizeyi orijinal dizeyle değiştirerek her zaman "tersine" değiştirme çalıştırabilirsiniz. Bu nedenle, yedek dize boşsa veya vikide zaten var olan bir dizeyse, kullanıcıya bir uyarı mesajı gösterilir.

Arama dizesi bir sayfada birden çok kez yer alıyorsa, bu tür her örnek değiştirilir. Her sayfanın değiştirilenleri (küçük) bir viki düzenlemesi olarak görünür, metin değiştirmeyi yapan yönetici düzenlemeyi yapan kullanıcı olarak ve bir düzenleme özeti "Metin değiştirme: ' arama dizesi ile ' değiştirme dizesi '" gibi görünür.

Bir sayfanın başlığı, vikide zaten var olan bir başlığa veya birden çok satırdan oluşan bir başlığa taşınamaz. Taşınamayan sayfalar, yanlarında bir onay kutusu olmaksızın "seç" sayfasında taşınamaz olarak listelenir.

The search is case-sensitive. See below for how to make it case-insensitive.

Things to know

 * 1) ReplaceText only processes 250 pages at a time by default. To change this, you can set   to a larger value in your LocalSettings.php. However, you may be limited by PHP's ; if the extension reports such a warning, you may need to change it.
 * 2) All of the replacements are placed in the job queue. So if you have to process a large number of pages, you will need to run Replace Text and then run " " (potentially multiple times).

Using regular expressions
If you are using a MySQL or PostgreSQL database, you will see a "Use regular expressions" checkbox within the Special:ReplaceText form. This checkbox does not appear for MS SQL/SQLServer or SQLite databases, because these database types lack a native "REGEXP" operator.

If you click on this checkbox, you can use regular expressions, or regexps, within the search and replacement strings. The set of regular expressions allowed is basically a small subset of the PHP and MySQL/PostgreSQL regular-expression set. The special characters that one can use in the search string are " . * + ? [ ] |", and within the replacement string one can use values like $1, $2 etc. (To use these as regular characters, you just need to escape them by adding a "\" beforehand - which you would also need to do with the "/" character.) This section will not give a tutorial on using regular expressions (the Wikipedia article is a good place to start for that, as is this page on MySQL regexps), but here is the basic example listed in the inline explanation:


 * Search string:
 * Replacement string:

This would look for pages containing the letter 'a', the letter 'c', and any text in between (signified by the ".*"). It would then put that middle text after the 'a' and 'c' - the "$1" in the replacement string refers to the first element of the search string contained within parentheses (in this case, there's only one).

For every page for which the replace is actually called, the replacement would happen for every occurrence of the search string, not just one - just as happens with regular, non-regular-expression search.

More complex regexps

 * Search string:
 * Replacement string:

This would replace "hello222.555" with "222,555" and "hello2.55" with "2,55"

First the word "hello" is matched. In brackets follows an expression to search for any digits "0-9". The following asterisk finds multiple matches of the preceding element. The brackets and the asterisk get enclosed with parantheses, so we match the complete term and transfer it to $1. The "\." indicates that it's a true dot, and not a special character. The second expression within parentheses is matched and put into $2.

Replacements followed by numbers
The following will not work:
 * Search string:
 * Replacement string:

That's because the search will think the number of the replacement is 1123456, not 1. Instead, you should have the following:
 * Replacement string:

In general, you can always enclose numbered values in curly brackets.

Case-insensitive search
To make your search case-insensitive, use regular expression and the case-insensitive modifier, :
 * Search string:
 * Replacement string:

The above will unify the casing of all mentions of iPhone/iphone/IPHONE to iPhone.

Command-line script: replaceAll.php
Replace Text offers a script, replaceAll.php, which can be run from the command line, and which does all the same replacements that the page Special:ReplaceText does. The first two arguments for this script should be the search text and the replacement text; you can call this script simply like the following: php replaceAll.php "Leningrad" "St. Petersburg"

Other possible arguments/flags for this script are:
 * - only find the search texts, without doing any actual replacements
 * - regular expressions should be used (default is false)
 * - the user to attribute the replacements to (default is the user with ID 1)
 * - skip all prompts with an assumed "yes"
 * - set a custom edit summary for the replacement edits
 * - rename page titles instead of replacing contents
 * - do not announce edits on Special:RecentChanges or watchlists
 * - set a comma-separated list of the namespaces to search
 * - search on all the namespaces; overrides any value set for "--ns"
 * - the name of a file holding a tab-separated list of replacements to make
 * - display the replacements being made

Additionally, there are two flags that strictly print out helpful information unrelated to a specific text replacement:
 * - show a description of the file format to use with
 * - show a list of all namespaces on this wiki

(You can also see all of these options by calling "php replaceAll.php --help".)

Assigning replacements to a user
By default, all replacements are credited in the page history to the user who initiated them. However, you can instead have replacements be credited to a pre-set user -- such as a bot account -- by adding a line like this to LocalSettings.php, below the inclusion of Replace Text:

The username specified must already be an account on the wiki. It will be added to MediaWiki's array of usernames which may not be registered or logged in from.

Important contributions were also made by Niklas Laxström, Ankit Garg (who contributed much of the regular expression code), Mark Hershberger (who wrote the command-line script), Brent Laabs, Cindy Cicalese and Nikhil Kumar.

Version history
Replace Text is currently at version 1.4.1. See the entire version history.

Screenshots
Below are images of the workflow of Replace Text. First, the initial page in which "George F. Will" and "George Will" are entered for the target string and replacement string, respectively, and replacing text in page titles is specified as well, on Discourse DB:



Note: the check "All" and "None" boxes only show up when using the Vector skin, or skins based off of it.

And here is what the page looks like after the user hits "Continue":



Hitting "Replace" would replace this value in all of the listed pages, as well as moving the page at the end to its new value.

Known issues

 * The replacement actions themselves are structured as MediaWiki "jobs", to ensure that the system is not overloaded if the user wants to do many at the same time. This means that a large set of replacements will not be done immediately, and may take minutes, hours or even longer to complete. Normally, jobs get activated every time a page is viewed on the wiki; to speed up the process (or slow it down), you can change the number of jobs run when a page is viewed; the default is 1. Thus a Replace Text request can stall soon after it starts if there is not enough front-end activity on the wiki to outrun the other sources of new batch jobs. For information on how to change the default, see the  page. To force the wiki to run all jobs immediately, go to the shell and execute the script ; there generally isn't a way to do this from the wiki's front end.
 * If you are still having a problem with getting Replace Text's jobs to run, adding the following to LocalSettings.php may fix the problem:


 * In order for redirects not to be created on page moves (i.e. if the "Save the old titles as redirects to the new titles" checkbox is unchecked), you will have to give the relevant user the 'suppressredirect' permission. Assuming you've given the 'replacetext' permission to a "trusted-editor" user group, you would need to add the following to LocalSettings.php:


 * If your revisions are compressed (that is, if is enabled in  or the script  has been executed with the option  ) then ReplaceText will not work, because it makes use of SQL queries that can't search compressed text. (see the MassEditRegex extension as an alternative in this case.)
 * If you have a large number of replacements, some of them may not get done; or you may see an error message that reads "You must select at least one namespace." In both cases, that's due to a limit on the number of form inputs that PHP accepts. This can be fixed in a number of ways:
 * If you have the Suhosin PHP extension installed on your server, that may be source of the problem. You can increase the value of the variables  and  ; or simply try temporarily disabling Suhosin while you do the replacements.
 * The PHP setting  (available since PHP 5.3.9) also affects the number of replacements you can do at any time - you can try setting this to a very large number, like 3000.
