Generate Custom Code by Using IDE-Specific Callback Functions

Replace strings, add custom headers, print a list of variables, and so on by generating custom code. Customize the code generated for supported target IDEs by creating IDE-specific custom callback functions. The custom callback functions can modify the generated code by using post-code generation callback functions or the intermediate controller cell array structure by using pre-code generation callback functions.

Custom Code Generation Workflow

To generate custom code for your target IDEs by using custom callback functions:

Create a custom pre- or post- code generation callback function. Place the callback functions on the MATLAB^® path.
Generate custom code by using Simulink^® PLC Coder™.

Create a Custom Callback Function

Create a custom pre-code generation callback function by using this template. Replace the Pre-Code Generation Callback File Name with the name of the pre-code generation callback file for your target IDE from the table. The pre-code generation function operates on the controller structure which contains information such as variable names, data types, and so on.

function controller = Pre-Code Generation Callback File Name(controller)
% add your custom actions here
end

Create a custom post-code generation callback function by using this template. Replace the Post-Code Generation Callback File Name with the name of the post-code generation callback file for the target IDE from the table. The post-code generation function performs operations such as replacing string values, adding a header to every code section, and so on.

function generatedFiles = Post-Code Generation Callback File Name(fileNames)
fileName = fileNames{1};
str = fileread(fileName); % reading the file contents%   do modifications to str here, f.ex.:
%   str = regexprep(str,'BOOL_TO_LREAL','BOOL_TO_INT');
%   str = regexprep(str,'<USINT/>','<INT/>');
%   str = regexprep(str, 'END_STRUCT','END_STRUCT;');
sfprivate ('str2file', str, fileName);
generatedFiles = {fileName};
end
