--headless $TOKEN flag, but for now we actually just create a one-off build of headless DiffPlug specific to the customer. This build will stop working after a year, and we trust the customer to not let their custom builds leak out into public.
The pricing for dp.simstate.headless is $4,750 (5x the cost of an interactive dp.simstate.differ license). But for every 10x dp.simstate.differ licenses you have, you get one free dp.simstate.headless license. We find that most customers investing in custom CI pipelines have at least 10 users anyway.

- B) ignore all blocks with a specific name

- C) ignore all blocks whose path matches a glob

Of these three, C seems the most flexible. Would it meet the needs of the problem you’re facing Ryan?

Downloaded and extracted the files into ~/DiffPlug
Try to start DiffPlug in terminal by calling the dp command in terminal

Makes sense since it the fist time i run the program and there is no file “/home/josef/.diffplug/.lock”

New in this release - Simulink
- Added support for
.slddfiles (details). - Some blocks with custom mask drawing code had their background and foreground colors set to white. Because DiffPlug can’t read all custom mask code, white-on-white is invisible, so the foreground color is now drawn as grey for these cases.
- When the label of a constant block is too long to fit, DiffPlug tries shrinking the font by 1 or 2 points.
Fixed in this release - Simulink
- Stateflow blocks whose ports have been reordered are now drawn in the correct position - no more unnecessary wire bends.
- Various bugs around drag-and-drop on the DiffList have been fixed.
New in this release - macOS

- Installers for Apple Silicon (M1, M2, etc) are now available for better performance on Apple Silicon machines.

- log4j has been entirely removed from DiffPlug.
- We used version 1.x which was not vulnerable to log4shell (see also this eclipse writeup as we share many dependencies).
- Dragging and dropping changed files in the commit diff viewer is fixed.
- When uploading a new branch to a remote, the
--set-upstreamtracking information wasn’t being saved to disk. Now fixed. - On MacOS only, DiffPlug startup could hang on proxy configuration when no network connections were available. Now fixed.
- Viewing and diffing folders which filenames containing

- When you mouseover the head branch, you now get a context-sensitive popup for downloading and uploading against that branch.

- Confirm dialogs which are triggered by the sync pane now automatically have keyboard focus.
- Faster feedback when removing a branch or tag from git tips.
- “Show help whenever I open a new git history window” was not respected, now it is.
- Cloning a git repository could sometimes fail starting in
2.6.0, now fixed. - Deleting remote branches and downloading branches which have been removed from the remote are now fixed.
- Attempting to
git pushand getting rejected because the remote has new commits now proactively prompts to download latest. - Retry attempts which needed a
--forcewere broken, now fixed.
New in this release - expert users
- Whenever you see a red X like below, you can right-click it to open a stacktrace dialog. In previous releases of DiffPlug, this was double-click, but now it is right-click. This change was needed to allow us to use the red X as a regular button in some important places, namely the git operation tracker.

- Folder diff via the

- Added support for R2021b.
- Note: we do not yet support the new Stateflow Entry and Exit mechanisms which were introduced in R2021b. They will be added in the next release.
My current pain involves signal logging. I haven’t figured out how to use the Simulink.Diff to detect changes in Signal logging. Can diffPlug see this change?
If you make a really simple model. Then make a copy, and add signal logging to one signal. Then diff them… you don’t see the difference. Even if you remove all the configured ignore criteria.
Can you please add this!

Can anyone give me some advice to read files faster?
Keep working on it for ten more years! 
You can still download DiffPlug 0.4.1 from July 2012, I bet it runs about the same speed as yours does.
The closest thing to a “trick” is to get experience with a profiler, VisualVM is the one we used the most with DiffPlug. Find the slowest part, then make it faster. Rinse and repeat for ten years, and at the end of that process you’ll have something as fast as DiffPlug!
If you want a shortcut, you can use the parser and renderer which is built-in to DiffPlug under the following licenses:
- for client-side applications, anyone with a DiffPlug license can use our API to make their own plugins for DiffPlug (including parsing and manipulating Simulink models)
- for server-side applications, we offer per-tool-developer pricing (e.g. team of 1, team of 5, etc.)
- for either case, we offer turnkey consulting where we deliver an initial app to your specifications for you, which you can maintain and modify from there
If you’d like to fast-forward your parser project to the end and start building tools, email us at [email protected] and we can discuss further.
]]>I’m working on a project related to Matlab .mdl file. My project is about an MVC web application that can allow users to upload their .mdl file, then my system will read it and push it to database to visualize. I have tried many ways to read mdl file with the fastest speed possible, include use read line by line and real all file algorithm. But all of them take ~ 30s for 1000 lines mdl file and about 8 mins for ~4000 lines mdl file. When I tried if DiffPlug, it takes only 5 seconds to read 4000 lines mdl file, and it is so impossible. Can anyone give me some advice to read files faster? Thanks! ]]>
