Hi,
Our forum has a lot of `[code][/code]` in its topics, imported from our old phpbb3 forum. One of our user reported a couple of bugs with `[code][/code]`. For example, this:
```plaintext
A single line of code without newline looks as a grey thick line:
[code]TString option = GetOption();[/code]
```
Gives:
A single line of code without newline looks as a grey thick line:
```plaintext
TString option = GetOption();
```
And in this other example, the `-- -----------------------------------------------------------` line gives another issue:
[code]hatiden@ubuntu:~$ gedit ~/.bashrc
hatiden@ubuntu:~$ cd /home/hatiden/garfield/
* * *
hatiden@ubuntu:~/garfield$ ls
[/code]
Cheers, Bertrand.

Discourse supports the BBcode but You need a line break after [code] block for it to work.
eg:
> [code]
> hatiden@ubuntu:~$ gedit ~/.bashrc
```plaintext
hatiden@ubuntu:~$ gedit ~/.bashrc
hatiden@ubuntu:~$ cd /home/hatiden/garfield/
hatiden@ubuntu:~/garfield$ ls
```

Well, not really, for example a line with embedded `TString option = GetOption();` works just fine…

Thanks!
Does that mean that our (old) imported code will stay unreadable with
```plaintext
single line examples code not having newline
```
?

It means you are going to need to apply some sort of processor on the old imported code if you want multiline bbcode to be converted from:
```plaintext
some text [code]
test
[/code] test
```
to:
```plaintext
some text
[code]
test
[/code]
test
```
It is quite a fiddly transform and I did not want it included in core.
If I were to attack this on an old imported corpus I would apply a transform to the `posts` `raw` column that inserts the missing newlines and then run a full rebake.

Thanks for the info, even if this is not exactly the issue we have… (multiline works quite well)

I have no idea what you’re talking about, but thanks anyway for the tips

Multiline works well as long it is not mixed!
This works:
```plaintext
[code]
test
test
[/code]
```
This does not:
```plaintext
a [code]
test
test
[/code]
```
This does not:
```plaintext
[code]
test
test
[/code]a
```
This does not:
```plaintext
[code]a
test
test
a[/code]
```

Oh, OK, I see. Well, I think our main issue now is the single line one (as in my first post)
I wasn’t even aware of the one you describe, so I suppose there should not be many…

If there are not many, I would recommend installing the [Discourse Data Explorer](https://meta.discourse.org/t/data-explorer-plugin/32566). Then you can find them and fix by hand. You just need to figure out the magic regex.

I will try (maybe), thanks. But the single line ones are many… would that tool be a solution?

Single line should `work fine`!
```plaintext
Single line should [code]work fine[/code]!
```
It only gets complicated when you start mixing.

Is this example considered as
```plaintext
mixing?
```
```plaintext

I would say this snippet not being handled correctly is a **bug**
```plaintext
Is this example considered as
[code]mixing?[/code]
```
It happens due to complications with optional newline handling in CommonMark

OK, so this was my original question, thanks! 🙂

Sure, be sure to edit the OP to talk about the specific example. I can have a look at it.
