Showybox is a Typst package for creating colorful and customizable boxes.

Please note that this repository contains the latest (development) version of this package and may not yet be published at Typst's official package repository. If you want to use this package, see https://github.com/typst/packages/tree/main/packages/preview for the latest stable version

To use this library through the Typst package manager (for Typst 0.6.0 or greater), write #import "@preview/showybox:2.0.2": showybox at the beginning of your Typst file.

Once imported, you can create an empty showybox by using the function showybox() and giving a default body content inside the parenthesis or outside them using squared brackets [].

By default a showybox with these properties will be created:

• No title
• No shadow
• Not breakable
• Black borders
• White background
• 5pt of border radius
• 1pt of border thickness

#import "@preview/showybox:2.0.2": showybox

#showybox(
  [Hello world!]
)

Looks quite simple, but the "magic" starts when adding a title, color and shadows. The following code creates two "unique" boxes with defined colors and custom borders:

// First showybox
#showybox(
  frame: (
    border-color: red.darken(50%),
    title-color: red.lighten(60%),
    body-color: red.lighten(80%)
  ),
  title-style: (
    color: black,
    weight: "regular",
    align: center
  ),
  shadow: (
    offset: 3pt,
  ),
  title: "Red-ish showybox with separated sections!",
  lorem(20),
  lorem(12)
)

// Second showybox
#showybox(
  frame: (
    dash: "dashed",
    border-color: red.darken(40%)
  ),
  body-style: (
    align: center
  ),
  sep: (
    dash: "dashed"
  ),
  shadow: (
	  offset: (x: 2pt, y: 3pt),
    color: yellow.lighten(70%)
  ),
  [This is an important message!],
  [Be careful outside. There are dangerous bananas!]
)

• breakable: A boolean indicating whether a showybox can break if it reached an end of page
• spacing: Space above and below the showybox
• above: Space above the showybox

  • y: Vertical anchor (top, horizon or bottom -- default is horizon)
  • x: Horizontal anchor (left, start, center, right, end -- default is left)
• offset: How much to offset the boxed title in x and y direction as a dictionary with keys x and y (default is 0pt)

• color: Shadow color (default is black)
• offset: How much to offset the shadow in x and y direction either as a length or a dictionary with keys x and y (default is 4pt)

• Revert fix breakable box empty before new page. Layout didn't converge

• Remove deprecated functions in Typst 0.12.0
• Fix breakable box empty before new page

• Fix bad behaviours of boxed-titles anchor inside a figure
• Fix wrong breakable behaviour of showyboxes inside a figure
• Fix Manual and README's Stokes theorem example

Special thanks to Andrew Voynov (https://github.com/Andrew15-5) for the feedback while creating the new behaviours for boxed-titles

• Update type() conditionals to Typst 0.8.0 standards
• Add boxed-style property, with anchor, offset and radius properties.
• Refactor showy-inset() for being general-purpose. Now it's called showy-value-in-direction() and has a default value for handling properties defaults
• Now sharp corners can be set by giving a dictionary to frame radius (e.g. radius: (top: 5pt, bottom: 0pt)). Before this only was possible for untitled showyboxes.
• Refactor shadow functions to be in a separated file.
• Fix bug of bad behaviour while writing too long titles.
• Fix bug while rendering separators with custom thickness. Now the thickness is gotten properly.
• Fix bad shadow drawing in showyboxes with a boxed-title that has a "extreme" offset value.
• Fix bad sizing while creating showyboxes with a width of less than 100%, and a shadow.

• Added boxed option in title styles
• Added boxed-align in title styles
• Added sep-thickness for title and footer
• Refactored repository's files layout

• Fixed shadow displacement
  • Details: Instead of displacing the showybox's body from the shadow, now the shadow is displaced from the body.

Changes below were performed by Jonas Neugebauer (https://github.com/jneug)

• Added title-inset, body-inset, footer-inset and inset options
  • Details: title-inset, body-inset and footer-inset will set the inset of the title, body and footer area respectively. inset is a fallback for those areas.
• Added a sep.gutter option to set the spacing around separator lines
• Added option width to set the width of a showybox
• Added option align to move a showybox with width < 100% along the x-axis
  • Details: A showybox is now wrapped in another block to allow alignment. This also makes it possible to pass the spacing options spacing, above and below to #showybox().
• Added footer and footer-style options
  • Details: The optional footer is added at the bottom of the box.

All changes listed here were performed by Jonas Neugebauer (https://github.com/jneug)

• Added the shadow option
• Enabled auto-break (breakable) functionality for titled showyboxes
• Removed a thin line that appears in showyboxes with no borders or dashed borders

• Improved code documentation
• Enabled an auto-break functionality for non-titled showyboxes
• Created a separator functionality to separate content inside a showybox with a horizontal line

• Changed package name from colorbox to showybox
• Fixed a spacing bug in encapsulated showyboxes
  • Details: When a showybox was encapsulated inside another, the spacing after that showybox was 0pt, probably due to some "fixes" improved to manage default spacing between rect elements. The issue was solved by avoiding #set statements and adding a #v(-1.1em) to correct extra spacing between the title rect and the body rect.

• Initial release
