Forum messing up pasted code

Feedback Forum Feedback

Hi,

Recently, I have received feedback from fellow forum members that what I have pasted looks incorrect when viewed on the web forum.

That seems something new, as it has not happened in the past.

It’s also incorrect in generated emails.

I dont think it is new and I have commented on it in the past. I dont
know if it only affects users who post via email: it has affected me.
It should be absolutely prohibited for discourse to mess with text
inside code fences, and this would be a major bug if so. I dont know if
we can find a simple case. Here’s a pipe:

ps aux | grep qubes

It looks as if this may be an artifact from Qubes copy/paste - if I copy a
pipe with standard inter qube copy/paste it is not pasted as a pipe -
sanitised?

@qubist - check to see what you actually posted.

I can’t reproduce this. I just copy-pasted this between qubes successfully, without any issues:

echo asd | grep a

Does it depend on the terminal in use and also, how the clipboard is
populated? (eg Xterm, selectToClipboard? vi ? ). Many variables.

This is the message body source from my mail client:

And the second one:

I don’t think so. Otherwise the message in the mail client and in susepaste would be messed up to, which is not the case.

Test:

> hello

Should read as greater than hello

> hello

Should read as vertical line before hello

Same with 4 spaces prefix:

    > hello
    > hello

Same with tab prefix:

	> hello
	> hello

Same with tab + 4 spaces prefix:

	    > hello
	    > hello

OK, confirmed:

The forum converts leading vertical line to ‘>’, with or without empty space before it.

More testing:

eb4f84ef043db492c7d102bf7e357ee033[foo

Should read as backslash 033, left square bracket and ‘foo’.

10

The second test reveals that the forum translates backslash into ‘eb4f84ef043db492c7d102bf7e357ee’.

Both tests were typed directly, nothing was pasted. That excludes Qubes clipboard.

Also looking at my older posts containing bash source code, I don’t see such issue.

I confirm @qubist observations.

It might be a discourse issue?

@unman

P.S. all your fullstops, asterisks and brackets in this post are backslash escaped in the plaintext email message body:

What a strange and unwelcome bug!

@unman

In your recent post each apostrophe shows as three question marks - in email and on the web page.

Could you please check if it may be due to your email client? Or maybe another forum bug?

16

It was terminal settings on the machine I was on. I dont hear those marks, so they can slip by.

Thanks for the feedback.

Characters in some posts started to show in mails prefixed by a backslash.

E.g. the square brackets in:
