Module documentation

This module is used to format Synchbot requests. The following functions are defined.

Request

edit

Arguments

edit

Renders a Synchbot request log which summarises the actions performed in response to this request. The following arguments are defined:

all requests
parameter usage
user The name of the user whose user pages to edit. This will be used by the bot to skip wikis where the user isn't registered.
action The action to perform on each page; one of delete, replace/prepend/append (for edit), or set (for preferences).
skip wikis An arbitrary list of wikis to skip.
status The status of the request; one of queued (default), done, not done, or on hold.
'edit' requests
title The title of the page to edit on each wiki (including namespace).
text The text to write to the page.
skip existing Whether to skip wikis where the page already exists ('yes' or blank).
'set' preferences requests
set:* The preferences to set as key:value pairs, like set:language = en.

Example (edit pages)

edit
{{#invoke:synchbot|request
  |user          = Pathoschild
  |action        = replace
  |title         = User:Pathoschild/common.js

  |skip wikis    = 
  |skip existing = 
  |status        = done
}}
request done:
Pathoschild (global account · recent activity · user pages)
  • go to User:Pathoschild/common.js on every wiki
  • and replace the text with
    mw.loader.load('//meta.wikimedia.org/w/index.php?title=User:Pathoschild/global.js&action=raw&ctype=text/javascript');

  |set:language  = en
  |set:skin      = vector
  |skip wikis    = 
  |status        = done

request done:
Pathoschild (global account · recent activity · user pages)
  • go to every wiki

    • Set language to en

edit_summary = None,

Arguments

edit

Renders a Synchbot request log which summarises the actions performed in response to this request. The following arguments are defined:

parameter usage
log The logged actions to output, as a multiline sequence of comma-separated values. Each line should consist of three fields: the time (like "00:53"), page link (like "[[s:User:Pathoschild|en.wikisource.org]]"), and log message (like "created (+116)"). Each message will be formatted by matching the log message for common patterns.
indent (optional) The number of times to indent the output, corresponding to the indentation level of a threaded wiki discussion.
counts:* (optional) Adds to the page counts used to build the summary bar graph. This is used to show an accurate summary even though some pages aren't listed (like page-doesn't-exist entries for a deletion request). Valid count keys: created, updated, deleted, missing (for missing user), skipped.

Example (no arguments)

edit
{{#invoke:synchbot|log|
     00:53,[[w:User:Pathoschild|en.wikipedia.org]],created (+116).
     00:53,[[s:User:Pathoschild|en.wikisource.org]],deleted.
     00:55,[[wikt:User:Pathoschild|en.wiktionary.org]],updated (+116).
}}
The following log shows what the bot did on each wiki. You can click the columns to sort the log.
summary:
timewikilogged action
00:53en.wikipedia.orgcreated (+116).
00:53en.wikisource.orgdeleted.
00:55en.wiktionary.orgupdated (+116).

Example (with arguments)

  |indent = 3
  |log    = 
     00:53,[[w:User:Pathoschild|en.wikipedia.org]],created (+116).
