How to create new .txt files named like the saved models in a folder and show Diag. View. information of each model in these files seperately?

Hello people,

i am stuck with the following code, because I can't create new txt files by naming them as same as name of my saved Simulink models in the same folder. Besides I want the code to write the whole information from Diagnostic Viewer to these txt files due to consistency between model's name and txt file's name separately.

F.e. Simulation1.txt about Simulation1.slx

Simulation2.txt about Simulation2.slx etc.

Also I hope that you can help me for it.

Thank you very much in advance!

PATH = 'C:\Users\xxx\Documents\Saved_Models';
TxtFiles = fullfile(PATH, '*.txt');
allTxtFiles = dir(TxtFiles);
for i=1:nFiles
    %Codes for simulation run
    %---%
    handles.txtFilename = allTxtFiles(i).name;
    Filename = fullfile(PATH, handles.txtFilename);
    fid = fopen(Filename);
    %sprintf('Simulation%d.txt', i);
    sldiagviewer.diary(handles.txtFilename);
end

PATH = 'C:\Users\xxx\Documents\Saved_Models';
TxtFiles = fullfile(PATH, '*.txt');
allTxtFiles = dir(TxtFiles);
for i=1:nFiles
    %Codes for simulation run
    %---%
    handles.txtFilename = allTxtFiles(i).name;
    ...

nFiles isn't defined...???? Whassup w/ that?

nFiles=numel(allTxtFiles);

I don't see any point in creating a struct handles; why not just use the returned file name as is?

I "know nuthink!" about Simulink as far as the other question whatever the diary procedure does and whether it can take a filename or needs a file handle or whether it can even do anything beyond writing to console you'll have to research the doc to see...

Oh, probably more nearly what you're looking for would be something otoo--

PATH = 'C:\Users\xxx\Documents\Saved_Models';
dSlx = dir(fullfile(PATH, '*.slx'));
for i=1:numel(dSlx)
  txtFname=fullfile(PATH,strrep(dSlx(i).name,'.slx','.txt'));
  ...

From there on, the above caveats are in place...

[OK]

Hello dpb,

thank you very much for your answer! I tried your suggested code and it is ALMOST done what I exactly want. Indeed the creating and naming of these txt files work correctly, but I can't write the diag viewer information once to each txt file, I mean that f.e. I see the warnings of both Sim1 and Sim2 in Sim2.txt instead I should see only the ones of Sim2 in that txt file. In the following code you see what I mean:

PATH = 'C:\Users\xxx\Documents\Saved_Models';
files = dir( fullfile(PATH,'*.slx') );   %# list all .slx files
fileNames = {files.name}';
fileNames=sort(fileNames);
nFiles=numel(fileNames); 
TxtFiles = dir(fullfile(PATH, '*.slx'));
        for i=1:nFiles 
            x = fullfile(PATH, fileNames{i});  
            open_system(x);
            sim(x);
            txtFname = fullfile(PATH,strrep(TxtFiles(i).name,'.slx','.txt'));
            sldiagviewer.diary(txtFname);
        end

Also I hope that you have any suggestion to write these diag viewer warnings correctly (one by one).

Unfortunately, no. I have no idea whatsoever on that part or anything specifically related to Simulink--I've never even seen the product so have no klew whatsover...sorry.

However, some peculiarities are observed...

files = dir( fullfile(PATH,'*.slx') );   %# list all .slx files
fileNames = {files.name}';
fileNames=sort(fileNames);
nFiles=numel(fileNames); 
TxtFiles = dir(fullfile(PATH, '*.slx'));
...

Why are you dir()'ing the same thing twice't????

dir() returns files in sorted order in general but if not, you're not addressing the same name later on with the text file name as the sorted model filename...

PATH = 'C:\Users\xxx\Documents\Saved_Models';
files = dir( fullfile(PATH,'*.slx') );   %# list all .slx files
nFiles=numel(files); 
for i=1:nFiles 
  mdl=fullfile(PATH, files(i).Name));
  open_system(mdl);
  sim(mdl);
  sldiagviewer.diary(strrep(mdl,'.slx','.txt'));
end

I have no idea what the Simulink stuff really does, but at least the above will keep the two filenames in synch and eliminates some duplication.

[OK]

The result of your new suggestion is the same as the previous one. But thanks!!

Well, reading the documentation, looks like that would be pretty-much the expected result...read that page and example code carefully...in particular note the following comment:

...
sldiagviewer.diary('off') % Switch off logging.
open_system('sldemo_fuelsys') % Any operation you do after the previous command will not be logged
rtwbuild('sldemo_fuelsys')
sldiagviewer.diary('on') % Resume logging in the previously specified log file.

The state is a toggle -- if it was on, a filename turns it off and vice versa. I'm guessing you need to look carefully at the sequence and if it is the sim(mdl) command that runs the model that you want logged, then that isn't going to be logged because you would need the .diary command before the sim(mdl) statement. Consequently, since it follows, looks like your text/logging files will always be one behind the actual. Which, if I interpret the comment correctly, is what you're seeing.

[OK]

I made it by rewriting it:

...
sldiagviewer.diary('off');
open_system(x);
f = open('GUI.fig');
figure(f);
sim(x);
sldiagviewer.diary('on');
sldiagviewer.diary(strrep(x,'.slx','.txt'));
close_system(x);
...

If you realized I wrote .diary('off') before open_system and .diary('on') after sim(x) and before .diary(strrep...). Also it is COMPLETELY done what I exactly want. Thank you again for your help!!!
