Autocompletion for Etherpad


It’s beta, but works. Please contribute and/or file bugs.


In its preconfigured form it completes words (searches the document for words, suggests existing words if you type them again). This add-on will require configuration if you want it to autocomplete anything else.

Pre-configured flags

  • processKeyEvent: define if ep_autocomp should handle ace key events (arrow keys, ENTER, etc). Default: true
  • processEditEvent: define if ep_autocomp should handle ace edit events (user editing a word). Default: true
  • showOnEmptyWords: define if suggestions should be displayed even when user didn't type any word. Useful for plugins that control when suggestions are displayed or not. Default: false
  • ignoreLatinCharacters: define if Latin characters should be considered the same as their non-Latin equivalents. Ex: user types "a", suggestions include words like "ál", "ão", etc. Default: false
  • enableShowSuggestionWithCtrlAndSpace: define if ep_autocomp should display the suggestions when user presses the shortcut CTRL + SPACE. Default: true

Advanced customization

Include stuff in settings.json

    "hardcodedSuggestions":[], //NOTE: insert your static suggestions here, e.g. a list of keywords. Must be a flat array with string values.
    "suggestWordsInDocument": true, // Use words in document to built a dictionary
    "enabled": false, // Enabled by default?
    "updateFromSourceObject": false, // Update the autocomplete suggestions from a different object
    "caseSensitiveMatch": true // Define if suggestions should respect case of typed words. Default: true
    // /(#\\w+)+/g  chains of hashtags. if you got "abc #first#second" you'll get "#first#second"
    // /(#\\w+)/g  get words with hash. if you got "abc #first#second" you'll get "#first","#second"
    //natural word matches:  /(\\w+)+/g
    //words in code (all non-whitespace, so strings with $, % etc, included) /(\\S+)/g

for customizing simple cases and the value autocomp.getPossibleSuggestions for more complex customizations.

Originally, this was written to autocomplete hashtags, you may want to complete from list of predefined keywords or from a hash of usernames after typing an @ etc. There are some examples in the sourcecode.


Open terminal, navigate to your etherpad folder and: type npm install ep_autocomp OR type git clone node_modules/ep_autocomp


Enable under pad settings (the gear icon)
