Hi,

I have created a custom toolbox. Now I'm trying to have a continuous development process that would automatically package the toolbox every midnight (if any of the files have changed). I'm trying to understand if it would be possible to update the toolbox project file programmatically - to change toolbox version, project file list, excluded file list, etc. I can then use the updated prj file to package the new toolbox.

Cheers,

sunny

I don't know of a documented way to generate the prj file the first time.

Yes I've been thinking the same thing. There doesn't seem to be a way to programatically update a matlab project file. This would be useful for the purposes of code maintenance from github. My continuous integration server could then be configured to build and distribute new releases of the toolbox when I commit to the master branch.

Workaround:

Given that the toolbox project file is just an xml under the hood, I knocked up some functions to update relevant sections of the project file using built-in xml editing functionality. Serves the purpose but a built-in solution would be much appreciated.

Hi Sunny,

I too would be interested in looking at your code.

Thanks,

在 MATLAB Online 中打开

Use readstruct and writestruct.

project = readstruct(fullfile(path,project_name.prj),'FileType','xml');
project.configuration.param_version = project_file.configuration.param_version + 1;
writestruct(project,fullfile(path,project_name.prj),'FileType','xml')
