mw-replace-bot

A Node.js tool using mediawiki to conveniently perform expressive find-and-replaces on wiki content (including regular expressions with callbacks).

NOTE: This project is very much experimental, and short of the potential it adds for your own replacements to be problematic, it may have its own bugs at this stage. Use at your own risk!

Installation

npm i mw-replace-bot

Usage

In a mw-replace-rc.js file in the same directory as mw-replace-bot, add the following and modify according to your site and replacement needs:

module.exports = {
  // REQUIRED ITEMS
 
  endpoint: 'https://site-to-be-queried.example/api.php',
  user: 'user@<my-bot-login>',
  password: 'my-bot-password',
  // The search can be more broad than the regex find,
  //   as entries found with `search` that are not found
  //   by `find` will not be modified; but currently a
  //   `search` is needed to get results out of the
  //   API and over the network; the `find` is
  //   post-processing done within Node
  search: 'search terms',
 
  // This can also be just a string in which case,
  //   regular expressions wouldn't apply and only
  //   a single instance would be replaced
  // For regular expressions in JavaScript, see https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/RegExp
  find: /a (regular) expression/gu,
 
  // Instead of a function, this can also be a
  //   regex replacement string: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/replace#Specifying_a_string_as_a_parameter
  // For function docs, see https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/replace#Specifying_a_function_as_a_parameter
  replace (n0, n1) {
    return n1; // Do replacements here
  },
 
  // OPTIONAL ITEMS
  autoContinue: true,
 
  // Disable actual editing
  readonly: true,
  // Logging in general
  logging: true,
  // Opt in to show the replaced text of the page in console (can be large)
  logReplacedText: true,
  // Suffix to add to edit summaries:
  byline: '(mw-replace bot edit)',
  // Summary for the batch
  summary: 'A summary for this batch of edits',
  // ms between API requests (Default: 6 secs)
  rate: 6e3,
 
  // Used in `User-Agent` header; `version` is that of `mediawiki` module
  // 1. Default for Node:
  // 'MediaWiki/' + version + '; Node/' + process.version +
  //    '; <https://github.com/oliver-moran/mediawiki>',
  // 2. Default for browser (once we may support):
  // 'MediaWiki/' + version + '; ' + navigator.userAgent +
  //    '; <https://github.com/oliver-moran/mediawiki>'
  userAgent: 'A string to use for the `User-Agent` header',
 
  // Continuing
  // Integer
  gsrlimit: 10,
  // One of:
  // "relevance", "just_match", "none", "incoming_links_asc",
  // "incoming_links_desc", "last_edit_asc", "last_edit_desc",
  // "create_timestamp_asc", "create_timestamp_desc"
  gsrsort: 'relevance'
};

To-dos

1. GUI
2. Expose a genuine bin script

Lower-priority to-dos

1. Ideally, update mediawiki to use ES6 Promise API and use here (with await/async)
2. Client-side browser support (including ESM)
3. Would ideally tie into SQL to actually do regex search rather than search and then find/replace
