websocat4 does not send enter characters.

[LaySoft]

I found a difference between websocat 1.13.0 and websocat4.

I pipe a command output to websocat like this:

ls -la | websocat wss://....

websocat 1.13.0 sends the enter characters (0x0a), but websocat4 don't.

What is the solution to make websocat4 also send the enter characters?

Do you want each line to be a separate WebSocket message or the whole ls output to be in one WebSocket message?

You can use e.g. --separator-n=2 to force two newlines be the separator instead of just one. You'll need an extra command to supply the second newline though.

{ ls -la; echo;  } | websocat4 --separator-n=2 ws://127.0.0.1:1234/

As a workaround for specifically forcing each message to end with a newline, you can use other byte as a separator (e.g. zero byte) and substitute each \n with \n\0.

ls -la | sed -z 's!\n!\n\x00!g' | /opt/websocat4 -U0 ws://127.0.0.1:1234/

Why do you want the message to end with newlines?

Is it specifically for ls or actual scenario is more involved?

Both websocat 1.13.0 and websocat4 send the output of the "ls -la" command line by line, each line is a separate message. This okay. But websocat4 does not send the enter at the end of each line, it truncates it. I want websocat4 to work the same way as websocat 1.13.0, i.e. to send the enters at the end of the lines.

Implemented --separator-inline option to make it preserve the \ns.
