Use right arrow symbol in menu macro

mariocup
I am using asciidoctor-pdf (Asciidoctor PDF 1.5.0.alpha.14 using Asciidoctor 1.5.5) and would like to configure the styles of the menu command.

Instead of using the default symbol I would like to configure "right single arrow"  (→) for HTML and pdf.

Is it possible?

Yes.

You can configure this in Asciidoctor PDF using the theme. See https://github.com/asciidoctor/asciidoctor-pdf/blob/master/docs/theming-guide.adoc#keys-menu

In your case, you probably want:

menu:
  caret_content: ' \u2192 '

For HTML, you'll need to supply a custom template for the inline_menu node. For example, see https://github.com/asciidoctor/asciidoctor-backends/blob/master/slim/html5/inline_menu.html.slim.

I would like the caret to be configurable via CSS. I made this possible in the EPUB3 converter. That needs to be backported to the HTML converter. See https://github.com/asciidoctor/asciidoctor-epub3/blob/master/lib/asciidoctor-epub3/converter.rb#L759-L771.

Since I wrapped the caret in a span with a class, it's possible to use CSS to hide the default content and use the before or after pseudo selectors to inject replacement content.

Cheers,

Hi Dan,

thanks for the hint.

I tried to use in my pdf theme:

```
caret_content: ' \u2192 '
````

The code

```
:experimental: true
...
menu:View[Zoom > Reset]
```

was generating the pdf output

View  \u2192  Zoom \u2192 Reset

I tried to change my yml file to:

```
menu:menu_caret_content: ' & #8594; '  
```

With this change I getting the expected result View → Zoom → Reset.

NOTE: You have to remove the space between & and #, but when I write it without the space it will be render automatically in the editor as →

The string has to be double quoted in order to use Unicode escape codes. The example in the docs is incorrect (and thus fooled me). I'll fix it!

Btw, you can see how it's define in the default theme here:
