This page contains instructions for FishEye's innovative 'side by side diff' view. This is an assistive source code viewing mode where you can see how a file's content has changed, compared on the left and right hand sides of the screen.

Opening side by side diff view

To open FishEye's side by side diff view,

2. Select a range of revisions to compare between.

4. Side by side diff view opens. The left and right panes can scroll independently, and the view stays anchored around a central point. Colour coding is used to illustrate where lines have been added (green highlights) and where lines have been removed (red highlights). Grey highlights indicate that a line's internal content has changed. Each addition or deletion is linked to the opposite window by a coloured triangle that links to the location of that change in the counterpart file.

Understanding side by side diffs

Features of the side by side diff screen are referenced in the annotated screenshot below.

1. Added lines are highlighted green, displayed in the right hand pane.
2. Edited lines are highlighted grey, with minor sections highlighted red and green to show deletions and additions.
3. Deleted lines are highlighted red, displayed in the left hand pane.
4. Gutter line numbers are permanent links ("permalinks") that can saved and sent to colleagues. When they open those links, the view will automatically open in side by side diff mode.

Alternative ways to open side by side diffs

From the FishEye Dashboard

You can also open side by side diffs from the Dashboard screens, by clicking the 'Delta' triangle icon next to an item when it appears in the stream of events. This will open the file in the diff view. If you have currently selected side by side diff as the viewing mode, then the diff will automatically be displayed in that mode. If not, you can select side by side diff from the 'View' menu.

From the Revisions History view

When in the revisions view, you can show a diff by checking the boxes next to two revisions, then clicking the 'Diff' button in the top control bar. If you have currently selected side by side diff as the viewing mode, then the diff will automatically be displayed in that mode. If not, you can select side by side diff from the 'View' menu.

You can also launch into a diff of the latest revision and the second most recent by clicking 'Latest Diff' in the top control bar.
