|
|
|
<p>The <a href="../doc/manual.html#addon_merge"><code>merge</code></a>
|
|
addon provides an interface for displaying and merging diffs,
|
|
either <span class=clicky onclick="panes = 2; initUI()">two-way</span>
|
|
or <span class=clicky onclick="panes = 3; initUI()">three-way</span>.
|
|
The left (or center) pane is editable, and the differences with the
|
|
other pane(s) are <span class=clicky
|
|
onclick="toggleDifferences()">optionally</span> shown live as you edit
|
|
it. In the two-way configuration, there are also options to pad changed
|
|
sections to <span class=clicky onclick="connect = connect ? null :
|
|
'align'; initUI()">align</span> them, and to <span class=clicky
|
|
onclick="collapse = !collapse; initUI()">collapse</span> unchanged
|
|
stretches of text.</p>
|
|
|
|
<p>This addon depends on
|
|
the <a href="https://code.google.com/p/google-diff-match-patch/">google-diff-match-patch</a>
|
|
library to compute the diffs.</p>
