Optional: Install the Rell Eclipse plugin

This topic contains instructions to install and update the Rell plugin for Eclipse.

Adding the Rell plugin to the Eclipse IDE

Once you have downloaded the Eclipse IDE, the next step is to add the Rell plugin.

  1. Go to the menu Help - Install New Software
  2. In the Install dialog, click Add, then type:
  1. Rell shall appear in the list. Select it and click Next >, then Finish.

  2. If a warning "You are installing software that contains unsigned content" appears, click Install anyway.

  3. Click Restart Now when asked to restart Eclipse IDE.

  4. Switch to the Rell perspective. Menu Window - Perspective - Open Perspective - Other, choose Rell.

Enable automatic updates for the plugin

When a new version of the Rell plugin is available, you need to update it in Eclipse. If the Rell update URL is configured, Eclipse automatically checks for updates.

To manually check for updates:

  1. Menu: Help - Check for Updates.
  2. If it shows that a new version of the Rell plugin is available, install it.

If you see the "No updates found" message, verify that the Rell update site is set.

  1. Click the available software sites link in the message dialog.

  2. If there is no Rell in the list, click Add to add it.

  3. Specify:

    and click Add.

If the Rell update site is in the list, but you see the "No updates found" message, try to reload the site:

  1. Click the available software sites link in the message dialog.
  2. Click Reload.

If you still see no updates, your Rell plugin must be up-to-date.


When a Rell editor is open, you can see the structure of its file (tree of definitions) in the Outline view (which is, by default, on the right side of the IDE).

There is also a Quick outline window that's activated by the CTRL-O (⌘O) shortcut. Type a name to find its definition in the file.

Problems view

The Problems view shows compiler warnings and errors found in all projects in the IDE. You update the list when saving a file.

Press CTRL-H (⌘H) to open the Search dialog. It allows searching for a string in all files in the IDE. Select the File Search tab, and enter the text to search for the filename pattern.

Results show in the Search view as a tree.


Git operations are available via a context menu: right-click a file and choose Team.

To commit files, click Add to Index, then Commit.

The file icon in Project Explorer indicates whether the file is a new, changed, or unmodified file.

The changed files need to look nicer. To change the way how they're displayed, go to the Window - Preferences (macOS: Eclipse - Preferences) menu, then Team - Git - Label Decorations:

  • On the Text Decorations tab: delete the ">" character in all text fields.

  • On the Icon Decorations tab: check the Dirty resources checkbox.

  • Click Apply and Close.

Now the files look much better:
