Created attachment 150555 [details] screenshot of trying to open typescript file SUMMARY *** NOTE: If you are reporting a crash, please try to attach a backtrace with debug symbols. See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports *** Opening a typescript file kind of hangs kdevelop because it seems to interpret it as some mpeg/video kind of media which should be "played". Looking at the tool systems and different options I got the feeling that it is mainly focused on C/C++ type of source codes. But it was sitting in my machine from a long time so I just wanted to use it. And I think it shouldn't behave so strange literally, at least a text editor kind of interface (with maybe some syntax highlighting) shouldn't be difficult for this kind of application. STEPS TO REPRODUCE 1. Open any typescript (.ts) file type. OBSERVED RESULT It tries to play it (and when tried open with option from right-click context menu, it suggests all those playing kind of applications). EXPECTED RESULT A simple text editor interface. Or maybe play the typescript file (if kdevelop really wants to play it) I tried as much as possible to play it but that also doesn't seem to happen. 😅 SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: (available in About System) KDE Plasma Version: 5.25.1 KDE Frameworks Version: 5.95.0 Qt Version: 5.15.5 ADDITIONAL INFORMATION
Cannot reproduce. How does Kate or KWrite open these files? In the bottom left corner of KDevelop, Kate and KWrite there is a mode selection button. What mode is selected for your typescript files by default? Does it work correctly when you set TypeScript mode manually?

I do have mode selection in Kate and KWrite in the bottom right corner but there is nothing like that in kdevelop. [Screenshot](https://pasteboard.co/08da8U1w5rOn.png) To confirm whether we both are talking about the same thing, the following screenshot is from kate which works as expected.

I think the mime type detection causes this. *.ts is a valid extension for video/mp2t, MPEG-2 Transport Stream, which is why kdevelop would load a kpart to try to play a video.

Assuming you don't have any valuable configuration there (if you do, create a backup), try removing ~/.config/kdeveloprc, ~/.local/share/kdevelop.
What does `kmimetypefinder5 foobar.ts` say for you? I indeed get `video/mpeg` back. You probably need to solve that via `File Associations` in `system-settings`, there you can screate a new text/x-typescript mimetype, that should hopefully fix it then. Or remove the .ts pattern from the other mime types. Generally though this is not something we can handle within kdevelop easily.

This allows opening *.ts files now after one [popup] (https://pasteboard.co/CH9RSk49CVNj.png) > Generally though this is not something we can handle within kdevelop easily. I wonder why I never faced this with other editors if *.ts was always there as video/mpeg type.
(In reply to amixra from comment #8) > This allows opening *.ts files now after one [popup] Oh that was because I had added it into application group following the convention of javascript. There isn't any popup after adding into text group.

So it only appears when a file is opened in KDevelop's text editor. By the way, "Cannot reproduce" in my earlier comment means that I tried opening several *.ts files and they were correctly recognized and opened as TypeScript by KDevelop on my system (Manjaro Xfce).
