13.6 Metrics

GPS provides an interface with the GNAT software metrics generation tool gnatmetric.

The metrics can be computed for the one source file, for the current project, or for the current project and its imported subprojects

The metrics generator can be invoked either from the Tools->Metrics menu or from the contextual menu.

13.6.1 The Metrics Menu

The Metrics submenu is available from the Tools global menu and contains:

Compute metrics for current file

Generate metrics for the current source file.

Compute metrics for current project

Generate metrics for all files from the current project.

Compute metrics for current project and subprojects

Generate metrics for all files from the current project and subprojects.

13.6.2 The Contextual Menu

When relevant (depending on the context), right-clicking with your mouse will show metrics-related contextual menu entries.

From a source file contextual menu, you have an option called Metrics for file that will generate the metrics for the current file.

From a project contextual menu (see The Project View), you have an option Metrics for project that will generate the metrics for all files in the project.

After having computed metrics, a new window in the left-side area is displayed showing the computed metrics as a hierarchical tree view. The metrics are arranged by files, and then by scopes inside the files in a nested fashion. Double-clicking on any of the files or scopes displayed will open the appropriate source location in the editor. Any errors encountered during metrics computation will be displayed in the Locations Window.
