Programmatically save all dirty files in MatLab - matlab

Question

Frequently I make the mistake of running my main.m when several files in the editor are dirty.
It would be nice if I could have a command at the start of my main.m that just automatically saves every dirty file.
Save currently running script in Matlab gives an answer with a clue for saving the currently active file, but is there a way to do this for ALL files?

You can use the com.mathworks.mlservices.MLEditorservice object to access the editor and save all dirty files.
service = com.mathworks.mlservices.MLEditorServices;
% Get a vector of all open editors
editors = service.getEditorApplication.getOpenEditors();
% For each editor, if it is dirty, save it
for k = 0:(editors.size - 1)
editor = editors.get(k);
if editor.isDirty()
editor.save();
end
end
Rather than blindly saving all files, you could modify this slightly so that you could pass a list of functions (your dependencies) and just save those.
function saveAll(varargin)
% Convert all filenames to their full file paths
filenames = cellfun(#which, varargin, 'uniformoutput', false);
service = com.mathworks.mlservices.MLEditorServices;
% Get a vector of all open editors
editors = service.getEditorApplication.getOpenEditors();
% For each editor, if it is dirty, save it
for k = 0:(editors.size - 1)
editor = editors.get(k);
% Check if the file in this editor is in our list of filenames
% and that it's dirty prior to saving it
if ismember(char(editor.getLongName()), filenames) && editor.isDirty()
editor.save();
end
end
end
And this could be called with multiple function names (as strings)
saveAll('myfunc', 'myotherfunc')
