flow

A bundle of template and a few more utils, written in and for Typst.

Quick start

#import "@preview/flow:0.4.0": *
#show: note.with(
  title: "Super cool title!",
)

The actual body text!

Or just typst init @preview/flow which does the same!

What's in here?

A set of utils for actual application. While there's many amazing libraries for Typst, such as cetz, cetz-plot or whalogen, often they're too flexible for just getting things down.

Flow aims to fill that missing spot between flexible unlimited libraries and ad-hoc application. It offers a set of explicitly biased defaults and different fields, but doesn't force them: Anyone can add or change them as-needed.

So, get ready for a quick tour on what's offered!

Notes

• Just typing some text and want some metadata, outline, formatting and todo lists? #show: note, that's it!
• Need to pass something through as LaTeX under significant time pressure? #show: template.latex-esque
• Want something rather custom while still getting the other utils? Use #show: template.generic anywhere in your template!

Callouts!

They're functions that accept content, e.g.:

#question[
  Are birds real?
]

• question, hint, remark and caution for quickly communicating intent of some text!
• axiom, define, theorem, propose, lemma and corollary for math and structured workflows!

Todo lists!

= Shopping list

- [ ] Still to do
- [>] Currently doing this
- [:] Some paused item
- [/] Aww this has been cancelled
- [?] Not sure what to do
- [!] *Really* need to do this

• Want something to be an unchecked task? Just make it a list entry in the form of - [ ] thing!
• Completed the task? Replace the space in the brackets with an x!
• In progress? Paused? Blocked? Cancelled? Unknown? Urgent? Just use other characters instead of x, like >, :, -, /, ? and !

Field-specific presets!

• Typing a lot of math? Check out preset.math (mostly just linear algebra for now)!
  • Bored of abs, bold, norm, arrow, tilde being too long to type? Common math characters are double-defined to have common shortcuts!
    • Bold x? xb
    • Vector c? cv
    • Conjugate transposed M? MH
    • Absolute value of vector p? pva
  • Null vector? null
  • Plane defined via 3 points? plp(a, b, c)
  • Want to quickly throw a function plot in? plot(x => pow(x, 2))
  • integral_(-oo)^oo is too long? iinf
  • Sum with index k starting at 1 ending at n? sk1n or even just sk1n
  • Limit of k towards infinity? limk(oo)

Themes!

• Controlled via the command-line inputs rather than the file you're writing!
• Pass --input theme=duality (or set theme to duality in your UI's inputs) for a nicer dark mode theme!
• In the file, use
  • bg for the background color!
  • fg for the foreground color!
  • gamut.sample(n%) to select n percent between background and foreground!

Metadata!

• Pass any extra arguments you want available to your template of choice!
• Some templates like e.g. note render them before the main content!
  • Some metadata like cw even highlights specially!
• If you just want to get the metadata out of a file without anything else, you can use typst query --input render=false which take on the text and is far faster!

Diagrams!

• Want to render a directed graph? Use gfx.diagram!
  • Pass
    • a dictionary as a keyword argument to nodes, keyed by name and position as value
    • a dictionary to edges, keyed by source and target as string
      • the target can also be several (all("a", "b", "c")) or in a row (seq("a", "b", "c"))!
  • Edges can be tagged, colored, stroked, branched!
    • E.g. tag("a", tag: [hi!]), styled("a", stroke: blue), br(br("a", "b"), "c")

I'm sold, where do I find out more?
