Configure Checkers for Polyspace as You Code at the Command Line

If you use an IDE that is not supported by Polyspace^® as You Code, you can check for defects and coding rule violations by using Polyspace as You Code at the command line. The default analysis checks for the default set of Polyspace Bug Finder™ defects. See Polyspace Bug Finder Defects Checkers Enabled by Default (Polyspace Bug Finder). To check for other defects and coding rule violations, configure Polyspace as You Code.

To configure checkers, you can reuse an existing checker file. Alternatively, you can create a checkers file using the Checkers Selection window. For equivalent workflows in the Polyspace desktop and server, see Prepare Checkers Configuration for Polyspace Bug Finder Analysis (Polyspace Bug Finder).

Configure Checkers and Coding Rules Directly at the Command Line

You can specify a selection of checkers and coding rules by using analysis options with appropriate values directly at the command line. For a list of analysis options related to checkers, see Coding Standards and Code Metrics (Polyspace Bug Finder) and Bug Finder Analysis (Polyspace Bug Finder).

For instance, to activate the performance checkers and MISRA™ C:2023 coding rule, use this command at the command line.

polyspace-bug-finder-access -sources sourceFile -checkers performance -misra-c-2023 all

Here, sourceFile is the source file you want to analyze. For the command line syntax of each option, see Complete List of Polyspace Bug Finder Analysis Engine Options (Polyspace Bug Finder). To view the results, use polyspace-results-export (Polyspace Bug Finder).

You can specify the checkers and coding rule options in an options file and reuse the options file in different analysis. An options file is a text file with one analysis option for each line. For example, to run the preceding analysis, create an options file CheckersOptions.txt that contains these options:

-checkers performance
-misra-c-2023 all

Specify the options file at the command line:

polyspace-bug-finder-access -options-file CheckersOptions.txt

For more details about options file, see Options Files for Polyspace Analysis (Polyspace Bug Finder).

By using analysis options directly at the command line or in an options file, you can select predefined subsets of checkers and coding rules. To select a customized subset of checkers and coding rules, configure checkers by using a checkers activation file.

Use Existing Checkers Activation File

You can use a checkers activation file (.XML) to configure checkers. A checkers activation file enables a set of Bug Finder defects and external coding rules. If you have an activation file, specify the file as an input the option -checkers-activation-file.

At the Linux^® command line, enter:

polyspace-bug-finder-access -sources sourceFile \
-checkers-activation-file PathToCreatedCheckerFile

At the Windows^® command line, enter:

polyspace-bug-finder-access -sources sourceFile ^
-checkers-activation-file PathToCreatedCheckerFile

Here, PathToCreatedCheckerFile is the full path to the XML checkers activation file.

Optionally, you can modify the selection of checkers in these files. Open the Checkers Selection window by using this command at the command line:

polyspace-checkers-selection

Navigate to the checkers activation file and modify the selection of checkers. Save your changes and reuse the file in subsequent analyses.

Import Checkers Configuration from Project

If you have a Polyspace desktop project file (.psprj), you can import checkers configuration from it. At the command line, enter:

polyspace-checkers-selection -import-options-from-psprj PathToProject

The command polyspace-checkers-selection is located in the folder polyspace/bin where polyspaceroot is the location of the Polyspace installation folder in your development environment.
PathToProject is the full path to the Polyspace desktop project (.psprj).

After you run the command, Polyspace creates a checkers activation file using the checkers configuration in the project. The checkers activation file is stored in the subfolder import folder in the same location as the .psprj file. Use the activation file as an input to -checkers-activation-file when running Polyspace as You Code at the command line.

For more details, see Generate Build Options for Polyspace as You Code Analysis at the Command Line.

Create Checkers Configuration

If you do not have a checkers activation file (.XML), you can create it by Checkers Selection window.

To open the Checkers Selection window, at the command line, enter:
```
polyspace-checkers-selection
```
In the Checkers Selection window, select the checkers that you want to activate. You can also activate predefined categories of defect checkers such as All, Default, High, Medium, and Low. See Classification of Defects by Impact (Polyspace Bug Finder). Similarly, you can activate predefined sets of coding rules that are defined by their standards.
- When selecting Guidelines > Software Complexity checkers, review their thresholds. If the default thresholds are not acceptable, specify a suitable threshold in the Threshold column. See Check guidelines (-guidelines) (Polyspace Bug Finder).
- When selecting Custom Rules, review the Pattern and Convention for the rules. See Check custom rules (-custom-rules) (Polyspace Bug Finder).
- To classify Bug Finder defects or coding rule checkers using your own classification tag , enter text in the Comment column of the Checkers selection window. Polyspace displays that text in the Results Details pane and in the Detail column of the Results List (if available) when you review results in the desktop interface, in Polyspace Access™, or in the Polyspace as You Code plugins.
  Note
  The custom text that you enter in the Checkers selection window is omitted in:
  Generated reports.
  The Polyspace desktop interface when you open results from Polyspace Access. This limitation applies only to Bug Finder checkers.
Save the selection as a reusable checkers activation file by clicking Save changes. Click Finish to close the window.

You can later reuse the checkers XML file as an input in to the option -checkers-activation-file.

Modify Checkers Behavior

To modify the default behavior of Bug Finder defect checkers and coding rules, use analysis options. For a list of analysis options that modify the default checker behavior, see Modify Default Behavior of Bug Finder Checkers (Polyspace Bug Finder).

To specify analysis options in Polyspace as You Code:

Use the options in the command line. For instance, to modify the trust boundary of your analysis, at the Linux command line, enter:
```
polyspace-bug-finder-access -sources sourceFile -checkers-activation-file CreatedCheckerFile\
 -consider-analysis-perimeter-as-trust-boundary
```
At the Windows command line, enter:
```
polyspace-bug-finder-access -sources sourceFile -checkers-activation-file CreatedCheckerFile^
 -consider-analysis-perimeter-as-trust-boundary
```
Here, CreatedCheckerFile is the XML checkers activation file and sourceFile is the full path to the source file that you analyze. You can specify multiple behavior modifying options in a single command.
Append the analysis options in the options file. An options file is a text file with one analysis option for each line. For instance, to add the analysis options -code-behavior-specifications (Polyspace Bug Finder) and Effective boolean types (-boolean-types) (Polyspace Bug Finder), in the options file, append these lines:
```
-code-behavior-specifications file1
-boolean-types boolean1_t,boolean2_t
```
where file1 is the path to a code behavior specification (.XML) file and boolean1_t,boolean2_t are boolean types.
If you do not have an existing options file, create an options file containing the necessary options. See Options Files for Polyspace Analysis (Polyspace Bug Finder).
