Run and Review Results in Polyspace as You Code for Eclipse

Step 2 of 3 in Perform Polyspace as You Code Analysis in Eclipse

After you configure the Polyspace as You Code plugin, you are ready to run an analysis and fix or justify any findings. Before continuing this guide, confirm you have added the files example.hpp and example_source.cpp to the Quality Monitoring list.

Run Polyspace as You Code Analysis in Eclipse

You can run an analysis in these ways:

If you select Start analysis on save, save your edited file to run an analysis.
Right-click in the file editor with your file open and select Run Polyspace Analysis.
Manually add your file to the Quality Monitoring list and click the Run Polyspace Analysis button in the Quality Monitoring pane to analyze your file.

Polyspace^® analyzes only files that are part of the Eclipse workspace. To add a file to a workspace, you add it to a project in that workspace. Files that are not in the workspace are not analyzed even if you add them to the Quality Monitoring list. If a file that you analyze includes a file that is not in the workspace, the Polyspace as You Code analysis runs but does not report any findings in the included file.

Manually Run Analysis

View, Fix, or Justify Findings

After Polyspace runs the analysis, the filename in the Quality Monitoring pane is green if there are no findings and red if there are findings. A number to the right of the filename indicates the number of findings.

View a list of your findings in the Polyspace Problems pane, which opens by default when you open the Polyspace as You Code perspective in Eclipse. If the Polyspace Problems pane is not open, reset the perspective by clicking Window > Perspective > Reset Perspective.

Use the filter in the Polyspace Problems pane to search for specific findings. Each finding contains a filename and line number to indicate where the finding exists in your code.

After you run an analysis on the example code:

Open the results in the Polyspace Problems pane.
Click the filter icon and create a new filter to search for the text A16-2-3. There is one result on line five.
Click the finding in the Polyspace Problems pane to open the file that contains the finding.
Each finding is noted in the file with a red highlight. Click the highlighted sections of code to see a list of each finding associated with the problem in the Result Details pane.
In the example code, add this #include statement on line two:
```
#include <cstdint>
```
Save this change and run another analysis. The A16-2-3 error on line five is no longer present.

If you set up automatic analysis, you can find and fix findings during the code authoring process. Each time you save changes, a Polyspace analysis begins in the background and displays any new findings or removes fixed findings from the list.

View and Fix Findings

Justify Individual Findings

You can justify a finding from the Polyspace Problems pane or from the location of the finding in the code.

Right-click a finding in the Polyspace Problems pane and select Polyspace. Select the appropriate justification from the menu. This adds a comment to your code, which you can amend. Adding a justification removes the finding from the Polyspace Problems pane. To show the finding again, remove the justification comment and perform an analysis.

Justify Findings

Provide Justification Catalog

You can add a catalog of predefined justifications to Polyspace as You Code. The justification catalog allows you to select a prewritten justification instead of manually entering each justification comment. The catalog must be in JSON format. If you do not already have a justification catalog, use this example JSON file.

example_catalog.json

{
	"justifications": [
		{
		"family": "Defect",
		"acronym": "INT_ZERO_DIV",
		"comment": "This is my justification for division"
		},
		{
		"family": "Defect",
		"acronym": "INT_ZERO_DIV",
		"comment": "Alternative justification for division"
		}
	]
}

Open the Eclipse Preferences and select Polyspace as You Code. Next to the Justification catalog text box, click Browse and navigate to your justification catalog.

Provide Justification Catalog

View Header Findings

When you analyze source files, you see any header file findings in the Polyspace Problems pane. If a header contains any findings, the findings are noted with a red H next to the source file in the Quality Monitoring list.

Double-click a header finding in the Polyspace Problems pane to go to the header file that contains the finding. The source file analysis that caused the header finding is listed in the Header column of the Polyspace Problems pane.
