It supports +collaborative editing using operation transforms (easysync2), +undo/redo, copy/paste. + +The name "ACE2" is because this is a rewrite of aiba's original +content-editable AppJet Code Editor. + +== Building it + +In this directory, run `bin/make normal etherpad` (requires scala), +which generates `build/ace2.js` and copies this and other files into +the etherpad source tree. To have the script keep running and +automatically rebuild when source files change, run `bin/make auto +etherpad`. + +The original reason for the build process was that ACE needs to +construct two nested iframes on the client, and to do this without +incurring round-trips to the server, it programmatically loads code +into the outer iframe that loads code into the inner iframe; so the +bulk of ACE's code is compressed into a string literal (twice). Later +on, refactoring meant that the source is also divided into more than a +dozen files that the build script combines, and some are also +server-side EtherPad modules or client-side libraries (or both). + +The master copy of the operational transform (OT) library, easysync2, +lives here. + +In the early days it was possible to run ACE in a sort of development +mode, without the compression and iframe injection, by running it out +of the 'www' directory, but this is no longer possible. + +== Browser support + +We went out of our way to support IE6+. IE's design-mode is quite +robust, though there are some differences in manipulation of the +selection and insertion point and in the DOM representation we had to +use. + +We don't support Opera. Opera is a problematic case, because +apparently JS running in different iframes is run concurrently, not +linearized into a single event thread. This seems to be a rather +obscure fact and is almost difficult to believe. As if iframes don't +complicate scripting enough! + +== Syntax highlighting + +Though syntax highlighting predated rich text as the original +motivation for the design of ACE, support was eventually dropped in +EtherPad. At first the plan was to generalize it to other programming +languages, but the task was deprioritized (and difficult), and during +subsequent optimization and refactoring of ACE, calls to the +incremental lexer were stripped out because they complicated things. + +One plan for multi-language syntax highlighting, never implemented, +was to calculate syntax highlighting on the server as a sort of "style +overlay" and feed updates to the client along with updates to the +document text. + +== Changeset format + +See easysync-notes.txt for some notes on the changeset format, which +was redesigned with the advent of rich text. diff --git a/trunk/infrastructure/ace/bin/backup.sh b/trunk/infrastructure/ace/bin/backup.sh deleted file mode 100755 index 82b75cb..0000000 --- a/trunk/infrastructure/ace/bin/backup.sh +++ /dev/null @@ -1,17 +0,0 @@ -#!/bin/bash - -# Copyright 2009 Google Inc. -# -# Licensed under the Apache License, Version 2.0 (the "License");
