codegen report.mldatx get *.m files

So someone has generated c code, we do not have the *.m files, but they are in the report.mldatx file which came with the code generation

we are 50% there, but are lookinig for code to do step 1

open report.mldatx with Matlab and click Export Report Information -> with name reportInfo

Even better if we can use a Matlab native function for this, due to be more robust for version update etc

What seems to work:

% by hand open report.mldatx with Matlab and click Export Report Information -> with name reportInfo

% Assuming 'reportInfo' contains the InputFiles

inputFiles = reportInfo.InputFiles;

% Check if inputFiles is not empty

if ~isempty(inputFiles)

% Save each InputFile as .m file using the function name

for i = 1:length(inputFiles)

% Extract the first line to get the function name

fileContent = inputFiles(i).Text;

firstLine = strsplit(fileContent, '\n');

% Check if the first line is not empty

if ~isempty(firstLine)

% Enhanced regex to match function definitions with multiple outputs

functionNameMatch = regexp(firstLine{1}, 'function\s+\[*.*\]*\s*=\s*(\w+)', 'tokens');

% Check if a function name was found

if ~isempty(functionNameMatch)

functionName = functionNameMatch{1}{1};

% Define the filename using the function name

filename = sprintf('%s.m', functionName);

% Write the content to the .m file

fid = fopen(filename, 'w');

fprintf(fid, '%s', fileContent);

fclose(fid);

else

warning('No function name found in the first line of InputFile %d', i);

end

else

warning('First line is empty in InputFile %d', i);

end

end

else

warning('InputFiles is empty in reportInfo');

end

Hi @Tijn,

The "coder.ReportInfo" properties contain information about code generation settings, input files, generated files, code generation messages, code insights, and build logs. A "coder.ReportInfo" object can only be created programmatically while doing the code generation by using the "codegen" command with the "-reportinfo" option at the command line. Specify the variable name after the "-reportinfo" option.

codegen myFunction -reportinfo info

For more information, please refer to the following documentation - https://www.mathworks.com/help/releases/R2022b/coder/ug/report-information-object.html?searchHighlight=coder.report&s_tid=srchtitle_support_results_3_coder.report

Thanks for your reply!!

1 think tough, we only have the file report.mldatx (codegen has long been done)

So we want extract the source *m files from file report.mldatx

so what we can do is:

open report.mldatx which opens Matlab's viewer

Then click Export Report Information -> with name reportInfo

But that way requires manual actions, we want this automated ; ))

As per the "Coder.ReportInfo" documentation page, there is no direct way to create this object. You have to export the code generation report to a variable in base worspace. Documentation - https://www.mathworks.com/help/coder/ref/coder.reportinfo-properties.html#:~:text=You%20do%20not%20directly%20create%20a%20coder.ReportInfo%20object.%20When%20you%20export%20code%20generation%20report%20information%20to%20a%20variable%20in%20your%20base%20MATLAB%C2%AE%20workspace%2C%20a%20coder.ReportInfo%20object%20is%20automatically%20created%20that%20contains%20this%20information

I understand that with codegen function this is output

But there is also the generated file report.mldatx

Matlab has a viewer to interpret and show the contens and since this viewer also can Export Report Information to a variable

And this variable has InputFiles which is the source code *.m files

So if the Matlab viewer tool can do the Export Report Information to variable,

we hope we can do that in code too ; ))

(This because we from embedded software get the generated code + report file)

So maybe my question is a feature request? (Or maybe there is a possibility outside of the mentioned documentation?)
