How can I "theme" an eval code block?

[halloleo]

Firstly, thanks heaps for patat. It's a great tool for terminal slides!

I am using figlet for some title slides:

---
patat:
  theme:
    codeBlock: [vividBlue, bold]
  eval:
    figletTitle:
      command: figlet -k -f big
      reveal: false
      replace: true
...

```figletTitle
What is Xonsh?
```

This code block is then rendered with the theming for code blocks (vividBlue), however I want these title in vividRed, so I do:

<!--config:
theme:
    codeBlock: [vividRed]
-->
```figletTitle
What is Xonsh?
```

This is a little bit cumbersome. Is there a way to set for figletTitle code blocks another theme than for real-code code blocks?

Sidenote: I was trying to reproduce this but couldn't. It seems like recent pandoc releases are downcasing code block classes (e.g. it's looking for figlettitle). I will fix that separately.

Back to the issue: there's currently no way to do this, but I think it's a good idea. It could look something like:

theme:
    codeBlock:
      default: [vividBlue]
      figletTitle: [vividRed]

A workaround for now could be to use an additional command (e.g. awk) -- this seems to work:

---
patat:
  eval:
    figlet:
      command: figlet | awk '{print "    \033[32m" $0 "\033[0m"}'
      reveal: false
      replace: true
      container: inline
...

```figlet
What is Xonsh?
```

Yes, I noticed the same - keeping the eval classes lowercase is an easy workaround.

theme:
    codeBlock:
      default: [vividBlue]
      figletTitle: [vividRed]

What would be a great way to do it. 😄

Makes sense. I will try this.

Now I have tried the awk hack.

However for me it doesn't fully work. Three problems:

1. The first line in the output is moved a few characters to the right:

   

2. I use the dissolve transition. Then during the transition the escaped characters are shown briefly in plain (i.e. escaped).

3. The presentation starts hanging after a few back-and-forth slide changes with a screen like this:

   

   Only multiple Ctrl-C can get me out of it.

I think the inline container doesn't work perfectly. -- Is there a way to see better what patat behind the scenes does?

Just in case the issues are related to my config:

A. Here the full YAML header:

---
title: '_'
patat:
  wrap: 60
  margins: 
    left: auto
    right: auto
  slideLevel: 1
  transition:
    type: dissolve
    duration: 0.3
  theme:
    emph: [vividBlack, italic]
    strong: [vividBlack, onDullWhite]
    header: [vividWhite, onVividBlack, italic]
    codeBlock: [vividBlue]
  eval:
    figlet:
      command: figlet | awk '{print "    \033[32m" $0 "\033[0m"}'
      reveal: false
      replace: true
      container: inline
...

B. Here my environment:

• OS: macOS
• Terminal: iTerm2
• patat version: 0.15.0.0 Using pandoc: 3.6.4
