A terminal contains only text information (if we except exploits such as w3m). Therefore, it is common to just paste those term information when it comes to show some CLI behaviour.
However, once the Pandora box of terminals is opened, yet another world reveals itself: ncurse. It is common to represent static elements with it using a screenshot, however as I already complained about it in another post. It is not a fully satisfactory solution as we also loose all the text information, and it is thus impossible to copy a part of the screen content without typing it again (or OCRise the screenshot?).
It’s quite straighforward to use, just invoke it in your favorite terminal emulator:
and it will save the resulting image in your temporary folder. You can also specify a target file, the geometry of the terminal you want to save, the template, etc.
A simple example:
termtosvg -g "82x19" -t progress_bar
Then you can simply embed it on your webpage as an example:
<object data="/examples/termtosvg-sl.svg">replacement text</object>
Warning: The resulting file is saved with read rights only to the owner of the file. Don’t forget to fix this before uploading the file. Doing otherwise may lead you to some surprises.
Remark: tested on firefox: you can also embed it as an image, but then you loose interactions and the possibility to select text, as you can see in the following example I used in this post produces by
termtosvg -g "82x30" -t window_frame_js
An example of broken decorations
Addendum 24/01/2020: I noticed that https://intoli.com/blog/terminal-recorders/ is also presenting different solutions for terminal recording.
