Crossref syntax not well supported with `non-space-sperated` situation

[mingsu]

Crossref syntax such as See @fig-demofiglabel is not well supported with no-space situation for docx output format.

WARNING: Unable to resolve crossref @fig-demofiglabel所示

For example:

如@fig-demofiglabel所示

I tried the syntax below, with no success

如@{fig-demofiglabel}所示

See @fig-demofiglabel

如@{fig-demofiglabel}所示

If I add a space before`@`, it works.

如 @{fig-demofiglabel}所示

```{r}
#| label: fig-demofiglabel
#| fig-cap: "Demo figure"
plot(1)
```

We use the pandoc syntax for citations to represent crossrefs and they don't appear to allow a space before the reference. So this behavior is as intended/supported.

[mingsu]

Understand.

But any way, is it possible to achieve this, since this space is excrescent for CJK language systems.

Is it possible to borrow some ideas from Rmarkdown syntax? which is avoided by add a prefix \:

\@ref(fig:demofiglabel).

[jjallaire]

We can't use that because \@ isn't technically part of the pandoc AST (it is identical to @ by the time it gets to pandoc). You could try using a zero-width-space (https://en.wikipedia.org/wiki/Zero-width_space).

[mingsu]

It's a good idea.

If this process can be done in quarto silently, that will be perfect, or leave user a option to active this.

say: replace @fig- in qmd file, and quarto replace @fig- to {Zero-width-space}@fig- before it pipes to pandoc.

[jjallaire]

That's a very good idea, I'll keep this issue open as a reminder to investigate this possibility.
