Bryan1 said So after my first failed attempt with MMEdit I deleted everything and re extracted the folder in /home/Bryan/mmedit5. Now trying to get MMedit to load an error comes up and fails to start.

I am working on a version for RPi without the need for webkit stuff.

Just waiting to create another clean image for the RPi.

If that works satisfactorily, I will do the same for other Linux.

You might still have difficulties with qt5. More recent distributions have gone to qt6 and removed it from their repositories.

"If that works satisfactorily, I will do the same for other Linux.". NO!!! mmedit on linux mint works great as is.

"If you want desktop shortcuts, run dtopscuts.sh.". shortcuts to mmedit and mmcc appear but just open files in file manager.

Thanks for your persistence sorting rpi mmedit... rpi programming rpi :)

@Jim. Brill! latest zip tar version WORKS! ... extracting was confusing, just zip was easier. Try flashing code next. Thanks again. regards stan

edit, just flashed the lissajours code and it works. got to remember groups dialup usb for it to use usb to ttl

Tried a few other flash progs and rpi mmedit working so far.

Nice :)

@Jim
just a thought: could it be possible to directly call the system default web browser with the help html instead of a GTK window?

edit: I don't own a RPI so could not test

Yes but in my experience it has been difficult to come up with a method that works for all incarnations of Linux.
I am working on it.

Fascinating thread.

@ Stan: Well done on keeping on with your tinkering. MANY people just give up on Linux, if it does not work right away, and the rest of them tend to give up if you DARE to mention the terminal!

I speak from experience - I was one of those a few years ago!

I will continue to watch this thread with interest.

Maybe something like

system("xdg-open filepath.html");

You may want to close stdout & stderr (if they're open to anywhere the user can see) to suppress unwanted output.

You may be best using a full path to the file.

Yes John, xdg-open seems to be the best contender.
I need to do some more testing but so far...

Trixie os linux can be frustrating for example the config.txt file has moved from /boot/config.txt to /boot/terminal/config.txt and is now "read only"!
I used chmod a+w /boot/terminal/config.txt in the terminal and ok. then right clicked config.txt and properties and it's accessible but when I edit it and try to save it says this file is read only.
The Trixie OS is on a 120G usb3 ssd and I used to plug into win pc to edit config.txt but that pc win 11 went tits up so it's linux mint and the config.txt shows as empty file. it's easy to get frustrated, well for me it is:)

To be fair, that DOES sound frustrating.

(And puzzling)

@Stan
Look at the file permissions in /boot/terminal:

ls -la /boot/terminal

I guess it's all root/root
In your filemanager right click and choose "open as administrator" and then edit it or use sudo in the terminal like

sudo xed /boot/terminal/config.txt

Edit:
Debian seems to use as default the text editor gedit so:

sudo gedit /boot/terminal/config.txt

sudo nano /boot/firmware/config.txt

also works if you prefer nano.

I haven't got admin access yet on rpi. seems a secret and why is config.txt now read only... stop people overclocking?
a search and others have tried to make config.txt writable with all methods and failed. weird. I'm not the only one. I'm using fresh images from rpi imager.
Jim's file zip/tar was lots of bother to extract. I tried newish Twister os 64bit on rpi but it couldn't extract mmedit.. gave up on it when it crashed.

Stan,
I don't have an arm64 platform so I installed Trixie for amd64 with cinnamon in a VM in order to help here.
In this version gedit is the default text editor.

Possible solutions:

Please find out by looking in accessories which editor is installed on your machine and replace gedit with yours in the command line.

The ASCII based editor "nano" should be installed, you could try

sudo nano /boot/terminal/config.txt

Good luck!

p.s. of cause there is vi/vim but that's a pain to use and to explain

stanleyella said I haven't got admin access yet on rpi. seems a secret and why is config.txt now read only... stop people overclocking?

I think it is owned by root and others like your user have only read access. You can open it but not change it.

Did you try? In your filemanager right click and choose "open as administrator" and then edit it

I almost can't believe that overclocking is configured in this text file. I'm interested, please post the content
