Displaying the current semantic context

The cedet-suite contains the semantic analyzer which is a library tool that performs context analysis and can derive useful information. See the related node in the info-manual of cedet/semantic for more detailed informations about this tool.

The analyzer output can be used through a special ECB-interactor. This interface lists details about the analysis, such as the current function, local arguments and variables, details on the prefix (the symbol the cursor is on), and a list of all possible completions (see semantic-analyze-possible-completions for more details about completions available via the semantic-analyser).

Per default the content of the analyser-interactor is automatically synchronized and updated with current point of the current source-buffer in the edit-area (see ecb-window-sync and ECB-window synchronizing).

The analyser-interactor is of type tree-buffer. See Tree-buffer basics for basic informations how to use such a tree-buffer.

Usage of the analyser-interactor

• When a node-name in the "Context"-bucket is selected with the primary mouse button (see Using the mouse) or RETURN (see Using the keyboard) the buffer in the edit-window (which one depends on the setting in ecb-mouse-click-destination) will jump to the related entry. For strongly typed languages, this means you will jump to the definition of the variable, slot, or type definition.
• Clicking on a node-name in the "Context"-bucket with the secondary mouse button or C-RETURN (see Usage of ECB) will jump to the related entry in another edit window - which one depends on the setting in ecb-mouse-click-destination.
• If you click on a node-name in the "Completions"-bucket, then the text that was recently analyzed will be replaced with the name of the tag that was clicked on in the analyser-interactor.
• Right clicking with the mouse (or with the keyboard, see Using popup-menus) onto a tree-node opens a popup-menu which allows to display additional (if available) informations to the current node.

  Interactive commands of the analyser-interactor

  ECB offers the following commands for the analyser-interactor:

  • ecb-analyse-buffer-sync
  • ecb-goto-window-analyse
  • ecb-maximize-window-analyse

  See Interactive ECB commands for details about these commands. But you should not have any need to call ecb-analyse-buffer-sync directly because ECB automatically syncronizes the analyser-interactor with current active edit-buffer.

Activating/Displaying the analyser-interactor

Either use one of the predefined layouts "left-analyse" or "leftright-analyse" (e.g. via C-c . l c) or create a new ecb-layout via the command ecb-create-new-layout and add a buffer of type "other" and name "analyse" into this new layout (see Creating a new ECB-layout).

Customizing the analyser interactor

See ecb-analyse for a list of all options currently available for customizing this interactor to your needs.
