I cannot quite figure out what it is in show rules. I have this example that I use to prevent line breaks on inline equations: #show math.equation.where(block: false): it => { box(it) } What is it exactly in this case? I am a bit puzzled that this just works, e.g. the correct math styling is sti…

A useful way to explore what things are is to use the repr() function. For instance: #show math.equation.where(block: false): it => repr(it) $1+2=3$ Results in: equation( block: false, numbering: none, number-align: end + horizon, supplement: [Equation], body: sequence([1], [+], [2], …

The right part of this show rule is an unnamed function . The show rule docs have other examples; using a function and show-set are the two fundamental forms of show rules. In the anonymous function, it is the parameter and is filled by the show rule with its target: the element that matched the sho…

So is the show rule above equivalent to replacing every #math.equation(block: false, ...) or $...$ with #box(math.equation(block:false, ...)) ?

Thanks a lot for the repr tipp. This allows me to explore things in typst myself instead of asking here :slight_smile:

[image] SebastianJL: So is the show rule above equivalent to replacing every #math.equation(block: false, ...) or $...$ with #box(math.equation(block:false, ...)) ? Exactly. As an aside, since your show rule’s function (it => box(it)) only calls box and nothing else, you can just use that…

[image] ensko: (the example is a bit more complex than it needs to be, as my-template is a function returning a function, but I wanted to write the example like I would actually write my templates) Why do you write your templates as functions? I do it like this: #let template(text-color: bla…

It comes down to the same thing, I do this too, because I prefer it that way, saves the unnecessary .with and looks a little cleaner IMO.

exactly to avoid the with :slight_smile: it’s a bit more effort (time and mental load) for the template author, but saves a bit for the template consumer. And hopefully the template will be used a bunch, so prioritizing that hopefully pays off :slight_smile:

I prefer the plain version that requires a with: I’m afraid that hiding it will obscure things for new users and push them in a “I don’t know what this is but it magically works” state of mind instead of learning the basics of the scripting language. But there’s probably no right answer, it’s all a…

I had the "I don’t know how it works, guess I’ll just write the with " moment :laughing: . To be honest, the documentation and the tutorials are not quite there yet where I am able to just search for things and have them easily explained. Especially on google the info is kind of hard to find.

Just mentioning this as I didn’t see it mentioned anywhere below. it is just a variable name. You can use any name that you want. It doesn’t have to be it.

What is the `it` in show rules exactly?
