Identifiers

Customize generated identifiers

You can configure how the code generator generates identifiers for code structures. Use identifier naming rules to generate identifiers that are meaningful, unique, and traceable.

You can control the maximum length of generated identifiers and include name-mangling text to avoid name collisions. You can use token decorators to control the content of an identifier using regular expressions. Certain keywords are not valid as identifiers, such as keywords from C and C++.

Topics

Identifier Format Control
You can customize generated identifiers by specifying the Identifier format control parameters on the Code Generation > Identifiers pane in the Configuration Parameters dialog box.
Specify Identifier Length to Avoid Naming Collisions
Use the Maximum identifier length parameter to limit the number of characters in function, type definition, and variable names.
Specify Reserved Names for Generated Identifiers
Specify a set of names that the code generation process should not use.
Customize Generated Identifier Naming Rules
Customize the naming of identifiers in the generated code.
Avoid Identifier Name Collisions with Referenced Models
Specify parameter values to avoid identifier name collisions with referenced models.
Control Name Mangling in Generated Identifiers
Specify the position and length of name-mangling text in generated identifiers.
Specify Boolean and Data Type Limit Identifiers
Integrate the generated code with your code by specifying the identifiers that correspond to Boolean false and true. Also, specify the identifiers that correspond to data type limits, which the generated code uses to determine overflows.
Reserved Keywords
If you use the code generator to produce C or C++ code, your model must not contain keywords that are reserved for internal use.
Maintain Traceability for Generated Identifiers
To verify your model, you can trace back and forth between generated identifiers and corresponding entities within the model.
Exceptions to Identifier Formatting Conventions
There are some exceptions to identifier formatting conventions for type names, non-Auto storage classes, and shared utilities.
Identifier Format Control Parameters Limitations
There are some limitations pertaining to how autogenerated identifiers comply with the setting of the Maximum identifier length parameter.
