Callouts are a great way to add more attention ot certain details of the text (in the form of a box). Quarto provides 5 different types of callouts:
notewarningimportanttipcaution.
The color and icon will be different depending upon the type that you select. You could preview them in the official documentation - Quarto - Callout Blocks. If you want to check the end effect jump directly to it here.
When writing your text directly in markdown compiled in Quarto you need to use pandoc div syntax
::: {.callout-note}
Note that there are five types of callouts, including:
`note`, `warning`, `important`, `tip`, and `caution`.
:::
When you want to edit your text in Obsidian obisidian doesnt pick the pandoc div syntax, instead it will have:
> [!note] My note
>
> Note content
There is no easy way to have nice formatted callouts in qmd/md files in Obsidian before compiling them to pdf/html
Pandoc can be supplemented by filters written by Lua that might some complex operations with source text.
I found a nice pandoc filter on the Obsidian forum, which I modified, so it support the default callouts in Quarto.
You need to save it as a pandoc filter and put inro your project folder and point to it when running quarto command (either via commandline or by putting it into you _quart.yml project settings.
In my case the file is called obsidian-callouts.lua and I point to it in the _quarto,yml in the root of the folder in the following section (I excluded irrelevant details):
project:
output-dir: _output
filters:
- filters/obsidian-callouts.luaContent of the file obsidian-callouts.lua :
local stringify = (require "pandoc.utils").stringify
function BlockQuote (el)
start = el.content[1]
if (start.t == "Para" and start.content[1].t == "Str" and
start.content[1].text:match("^%[!%w+%][-+]?$")) then
_, _, ctype = start.content[1].text:find("%[!(%w+)%]")
el.content:remove(1)
start.content:remove(1)
local class = "callout-" .. ctype:lower()
div = pandoc.Div(el.content, {class = class})
div.attributes["data-callout"] = ctype:lower()
div.attributes["title"] = stringify(start.content):gsub("^ ", "")
return div
else
return el
end
endAs a source I used this thread https://forum.obsidian.md/t/rendering-callouts-similarly-in-pandoc/40020/6
By default Obsidian recognize only note and warning callouts, to have the other 3 callouts the same icons and colors as in Quarto add the following CSS snippet quarto-callout-styllling to hidden .snippets folder and turn it on in the Obsidian appearance section of settings
/* See https://lucide.dev for icon codes */
/* annotation */
.callout[data-callout="important"] {
--callout-color: 251, 70, 76;
--callout-icon: lucide-alert-circle
}
.callout[data-callout="tip"] {
--callout-color: 28, 207, 110;
--callout-icon: lucide-lightbulb
}
.callout[data-callout="caution"] {
--callout-color: 255,153,102;
--callout-icon: lucide-flame
}After applying the css could see the difference between callouts in Live Preview in Obsidian
and PDF generated via Quarto
Below is the markdown used to generate it
> [!note] My note
>
> Note content
> [!warning] My note
>
> Note content
> [!important] My note
>
> Note content
> [!tip] My note
>
> Note content
> [!caution] My note
>
> Note contentWhile those snippets will ensure that your notes will render nicely in Obsidian, it may cause other editors that support Quarto to offer the same (altough) it will nice compile to pdf/html.
I didnt extensively test this Lua filter, so it might easily go broke in more complex cases and if you will try to use the callouts outside the one defined in Quarto by default.
In general I enabled Obsidian to see quarto files as md files via plugin, and then use obsidian-shellcomands with quarto render {{file_path:absolute}} --to pdf to render the file inside Obsidian (quarto is installed via homebrew on mac, this might work for linux, I am not sure about windows).
I also assigned this shellcomand to a button in my GUI via commander plugin (so I dont need to invoke it every time via command switcher when I want to re-run it on a file.
I created rudimentary plugin to support QMD files in Obsidian, in the Readme.md you could find more advices how to streamline work with your qmd files in Quarto:
danieltomasz/qmd-as-md-obsidian: A plugin for Obsidian which allows editing of qmd Quarto files.
Brilliant lua filter! Thanks for sharing your thinking process and the CSS to go back the other way.
This solves the main issue I had withthe Obsidian-Quarto workflow:
Do you know if it works with other Pandoc/Quarto divs and spans?
(I'll test this out myself. Just asking in case you already have.)
Any plans to add this to the qmd-as-md-obsidian plugin?
