Client-side hooks

Most of these hooks are called during or in order to set up the formatting process.

documentReady

Called from: src/templates/pad.html

Things in context:

nothing

This hook proxies the functionality of jQuery's $(document).ready event.

aceDomLinePreProcessLineAttributes

Called from: src/static/js/domline.js

Things in context:

domline - The current DOM line being processed
cls - The class of the current block element (useful for styling)

This hook is called for elements in the DOM that have the "lineMarkerAttribute" set. You can add elements into this category with the aceRegisterBlockElements hook above. This hook is run BEFORE the numbered and ordered lists logic is applied.

The return value of this hook should have the following structure:

{ preHtml: String, postHtml: String, processedMarker: Boolean }

The preHtml and postHtml values will be added to the HTML display of the element, and if processedMarker is true, the engine won't try to process it any more.

aceDomLineProcessLineAttributes

Called from: src/static/js/domline.js

Things in context:

domline - The current DOM line being processed
cls - The class of the current block element (useful for styling)

This hook is called for elements in the DOM that have the "lineMarkerAttribute" set. You can add elements into this category with the aceRegisterBlockElements hook above. This hook is run AFTER the ordered and numbered lists logic is applied.

The return value of this hook should have the following structure:

{ preHtml: String, postHtml: String, processedMarker: Boolean }

The preHtml and postHtml values will be added to the HTML display of the element, and if processedMarker is true, the engine won't try to process it any more.

aceCreateDomLine

Called from: src/static/js/domline.js

Things in context:

domline - the current DOM line being processed
cls - The class of the current element (useful for styling)

This hook is called for any line being processed by the formatting engine, unless the aceDomLineProcessLineAttributes hook from above returned true, in which case this hook is skipped.

The return value of this hook should have the following structure:

{ extraOpenTags: String, extraCloseTags: String, cls: String }

extraOpenTags and extraCloseTags will be added before and after the element in question, and cls will be the new class of the element going forward.

acePostWriteDomLineHTML

Called from: src/static/js/domline.js

Things in context:

node - the DOM node that just got written to the page

This hook is for right after a node has been fully formatted and written to the page.

aceAttribsToClasses

Called from: src/static/js/linestylefilter.js

Things in context:

linestylefilter - the JavaScript object that's currently processing the ace attributes
key - the current attribute being processed
value - the value of the attribute being processed

This hook is called during the attribute processing procedure, and should be used to translate key, value pairs into valid HTML classes that can be inserted into the DOM.

The return value for this function should be a list of classes, which will then be parsed into a valid class string.

aceAttribClasses

Called from: src/static/js/linestylefilter.js

Things in context:

Attributes - Object of Attributes

This hook is called when attributes are investigated on a line. It is useful if you want to add another attribute type or property type to a pad.

Example:

exports.aceAttribClasses = function(hook_name, attr, cb){
  attr.sub = 'tag:sub';
  cb(attr);
}

aceGetFilterStack

Called from: src/static/js/linestylefilter.js

Things in context:

linestylefilter - the JavaScript object that's currently processing the ace attributes
browser - an object indicating which browser is accessing the page

This hook is called to apply custom regular expression filters to a set of styles. The one example available is the ep_linkify plugin, which adds internal links. They use it to find the telltale [[ ]] syntax that signifies internal links, and finding that syntax, they add in the internalHref attribute to be later used by the aceCreateDomLine hook (documented above).

aceEditorCSS

Called from: src/static/js/ace.js

Things in context: None

This hook is provided to allow custom CSS files to be loaded. The return value should be an array of resource urls or paths relative to the plugins directory.

aceInitInnerdocbodyHead

Called from: src/static/js/ace.js

Things in context:

iframeHTML - the HTML of the editor iframe up to this point, in array format

This hook is called during the creation of the editor HTML. The array should have lines of HTML added to it, giving the plugin author a chance to add in meta, script, link, and other tags that go into the <head> element of the editor HTML document.

aceEditEvent

Called from: src/static/js/ace2_inner.js

Things in context:

callstack - a bunch of information about the current action
editorInfo - information about the user who is making the change
rep - information about where the change is being made
documentAttributeManager - information about attributes in the document (this is a mystery to me)

This hook is made available to edit the edit events that might occur when changes are made. Currently you can change the editor information, some of the meanings of the edit, and so on. You can also make internal changes (internal to your plugin) that use the information provided by the edit event.

aceRegisterNonScrollableEditEvents

Called from: src/static/js/ace2_inner.js

Things in context: None

When aceEditEvent (documented above) finishes processing the event, it scrolls the viewport to make caret visible to the user, but if you don't want that behavior to happen you can use this hook to register which edit events should not scroll viewport. The return value of this hook should be a list of event names.

Example:

exports.aceRegisterNonScrollableEditEvents = function(){
  return [ 'repaginate', 'updatePageCount' ];
}

aceRegisterBlockElements

Called from: src/static/js/ace2_inner.js

Things in context: None

The return value of this hook will add elements into the "lineMarkerAttribute" category, making the aceDomLineProcessLineAttributes hook (documented below) call for those elements.

aceInitialized

Called from: src/static/js/ace2_inner.js

Things in context:

editorInfo - information about the user who will be making changes through the interface, and a way to insert functions into the main ace object (see ep_headings)
rep - information about where the user's cursor is
documentAttributeManager - some kind of magic

This hook is for inserting further information into the ace engine, for later use in formatting hooks.

postAceInit

Called from: src/static/js/pad.js

Things in context:

ace - the ace object that is applied to this editor.
pad - the pad object of the current pad.

postToolbarInit

Called from: src/static/js/pad_editbar.js

Things in context:

ace - the ace object that is applied to this editor.
toolbar - Editbar instance. See below for the Editbar documentation.

Can be used to register custom actions to the toolbar.

Usage examples:

https://github.com/tiblu/ep_authorship_toggle

postTimesliderInit

Called from: src/static/js/timeslider.js

There doesn't appear to be any example available of this particular hook being used, but it gets fired after the timeslider is all set up.

goToRevisionEvent

Called from: src/static/js/broadcast.js

Things in context:

rev - The newRevision

This hook gets fired both on timeslider load (as timeslider shows a new revision) and when the new revision is showed to a user. There doesn't appear to be any example available of this particular hook being used.

userJoinOrUpdate

Called from: src/static/js/pad_userlist.js

Things in context:

info - the user information

This hook is called on the client side whenever a user joins or changes. This can be used to create notifications or an alternate user list.

chatNewMessage

Called from: src/static/js/chat.js

Things in context:

authorName - The user that wrote this message
author - The authorID of the user that wrote the message
text - the message text
sticky (boolean) - if you want the gritter notification bubble to fade out on its own or just sit there
timestamp - the timestamp of the chat message
timeStr - the timestamp as a formatted string
duration - for how long in milliseconds should the gritter notification appear (0 to disable)

This hook is called on the client side whenever a chat message is received from the server. It can be used to create different notifications for chat messages.

collectContentPre

Called from: src/static/js/contentcollector.js

Things in context:

cc - the contentcollector object
state - the current state of the change being made
tname - the tag name of this node currently being processed
styl - the style applied to the node (probably CSS) -- Note the typo
cls - the HTML class string of the node

This hook is called before the content of a node is collected by the usual methods. The cc object can be used to do a bunch of things that modify the content of the pad. See, for example, the heading1 plugin for etherpad original.

E.g. if you need to apply an attribute to newly inserted characters, call cc.doAttrib(state, "attributeName") which results in an attribute attributeName=true.

If you want to specify also a value, call cc.doAttrib(state, "attributeName::value") which results in an attribute attributeName=value.

collectContentImage

Called from: src/static/js/contentcollector.js

Things in context:

cc - the contentcollector object
state - the current state of the change being made
tname - the tag name of this node currently being processed
style - the style applied to the node (probably CSS)
cls - the HTML class string of the node
node - the node being modified

This hook is called before the content of an image node is collected by the usual methods. The cc object can be used to do a bunch of things that modify the content of the pad.

Example:

exports.collectContentImage = function(name, context){
  context.state.lineAttributes.img = context.node.outerHTML;
}

collectContentPost

Called from: src/static/js/contentcollector.js

Things in context:

cc - the contentcollector object
state - the current state of the change being made
tname - the tag name of this node currently being processed
style - the style applied to the node (probably CSS)
cls - the HTML class string of the node

This hook is called after the content of a node is collected by the usual methods. The cc object can be used to do a bunch of things that modify the content of the pad. See, for example, the heading1 plugin for etherpad original.

handleClientMessage_`name`

Called from: src/static/js/collab_client.js

Things in context:

payload - the data that got sent with the message (use it for custom message content)

This hook gets called every time the client receives a message of type name. This can most notably be used with the new HTTP API call, "sendClientsMessage", which sends a custom message type to all clients connected to a pad. You can also use this to handle existing types.

collab_client.js has a pretty extensive list of message types, if you want to take a look.

##aceStartLineAndCharForPoint-aceEndLineAndCharForPoint Called from: src/static/js/ace2_inner.js

Things in context:

callstack - a bunch of information about the current action
editorInfo - information about the user who is making the change
rep - information about where the change is being made
root - the span element of the current line
point - the starting/ending element where the cursor highlights
documentAttributeManager - information about attributes in the document

This hook is provided to allow a plugin to turn DOM node selection into [line,char] selection. The return value should be an array of [line,char]

##aceKeyEvent Called from: src/static/js/ace2_inner.js

Things in context:

callstack - a bunch of information about the current action
editorInfo - information about the user who is making the change
rep - information about where the change is being made

state - the current state of the change being made
tname - the tag name of this node currently being processed
text - the text for that line

This hook allows you to validate/manipulate the text before it's sent to the server side. The return value should be the validated/manipulated text.

##collectContentLineBreak Called from: src/static/js/contentcollector.js

Things in context:

cc - the contentcollector object
state - the current state of the change being made
tname - the tag name of this node currently being processed

This hook is provided to allow whether the br tag should induce a new magic domline or not. The return value should be either true(break the line) or false.

##disableAuthorColorsForThisLine Called from: src/static/js/linestylefilter.js

Things in context:

linestylefilter - the JavaScript object that's currently processing the ace attributes
text - the line text
class - line class

This hook is provided to allow whether a given line should be deliniated with multiple authors. Multiple authors in one line cause the creation of magic span lines. This might not suit you and now you can disable it and handle your own deliniation. The return value should be either true(disable) or false.
