Overlay image in terminal using ueberzug within C

QUESTION

Overlay image in terminal using ueberzug within C

Asked 2021-Dec-03 at 15:11

With the ueberzug library, it is possible to overlay images in terminal windows under X11. The library is written in python - examples for how to use the library are provided for bash and python.

To overlay an image in the terminal, one can simply run ueberzug layer and then enter a json formatted string like {"action": "add", "x": 0, "y": 0, "identifier": "test", "path": "/tmp/image.jpg"}. This works flawlessly.

I am trying to call this process in C. If I understand it correctly, I just have to spawn a new process, and then write to its stdin, which is normally a simple task.

However, in my case I can see the image flicker up for a fraction of a second before the application terminates. This is my code:

To summarize the comments, the following solution based on yours works:

By popen you fork a process, create a bidirectional pipe and start the command in the sub-shell
Subsequently, one writes to the pipe, issueing commands to ueberzug
the pipe however has to be fflushed, otherwise it's transferred only when the process exits
the signal handler catches the ueberzug child-process if the sub-shell is killed/quits

Meanwhile, main may continue running your code. The code below cycles through 3 images.

Vulnerabilities

No vulnerabilities reported

Install ueberzug

Note: You can improve the performance of image manipulation functions by using pillow-simd instead of pillow.
Install by using pip: The package is named ueberzug
Packages of linux distributions: At least one packager applies patches to my code. So if there are issues uninstall it and install it via pip. Actually I think it's not fine that they call it ueberzug after changing the code. As bugs introduced by them look like they are part of my work.

Support

The communication is realised via stdin. A command is a request to execute a specific action with the passed arguments. (Therefore a command has to contain a key value pair "action": action_name) Commands are separated with a line break.
