'ansi' output format can fail to format code

[phormio]

I have a file named test1.md:

<div>

| Blah | Blah | Blah | Blah |
| --- | --- | --- | --- |
| `title` | Y | String | HTML title. |
| `output_directory` | Y | String | Directory that contains blah blah blah. |

| a | b |
| --- | --- |
| `c` | `d` |
| `e_x` | `f` |

</div>

Using pandoc 3.10.1 on Linux, I ran this command

pandoc -t ansi test1.md

In the output, output_directory was formatted differently from all the other words that are in backquotes. It was formatted just like "String".

Another strange thing is that output_directory was one line lower than I would expect.

pandoc does know that output_directory is code. I proved that by running this command:

pandoc -t xml test1.md | xmllint --format - | grep -2 output_directory

Here is the output:

              <Cell alignment="AlignDefault">
                <Plain>
                  <Code>output_directory</Code>
                </Plain>
              </Cell>

I've tested in 2 different X11 terminal emulators and in the Linux console.

The screenshot below shows the output of pandoc -t ansi test1.md:

I see the same thing. @TuongNM @silby any ideas?

Seems to be a column width issue. With pandoc -t ansi --columns 80 test1.md it looks okay.

With the default column width the output_directory doesn't seem to fit and therefore gets wrapped which is probably why it's also vertically centered. Looks like the ansi escape codes are lost during the text wrapping process.

I'm not familiar enough with escape codes to offer a solution for how to handle wrapped text in a case like this.

I expect @TuongNM is on the right track with the vertical centering. The root cause probably lies in doclayout. A reproducer in code that only uses doclayout’s public API should help track it back down.
