Chic-header (chic-hdr) is a Typst package for creating elegant headers and footers

Usage

To use this library through the Typst package manager (for Typst 0.6.0 or greater), write #import "@preview/chic-hdr:0.5.0": * at the beginning of your Typst file. Once imported, you can start using the package by writing the instruction #show: chic.with() and giving any of the chic functions inside the parenthesis ().

Important: If you are using a custom template that also needs the #show instruction to be applied, prefer to use #show: chic() after the template’s #show.

For example, the code below…

#import "@preview/chic-hdr:0.5.0": *

#set page(paper: "a7")

#show: chic.with(
  chic-footer(
    left-side: strong(
        link("mailto:admin@chic.hdr", "admin@chic.hdr")
    ),
    right-side: chic-page-number()
  ),
  chic-header(
    left-side: emph(chic-heading-name(fill: true)),
    right-side: smallcaps("Example")
  ),
  chic-separator(1pt),
  chic-offset(7pt),
  chic-height(1.5cm)
)

Reference

Note: For a detailed explanation of the functions and parameters, see Chic-header’s Manual.pdf

While using #show: chic.with(), you can give the following parameters inside the parenthesis:

• width: Indicates the width of headers and footers in all the document (default is 100%).
• skip: Which pages must be skipped for setting its header and footer. Other properties changed with chic-height() or chic-offset() are preserved. Giving a negative index causes a skip of the last pages using last page as index -1(default is ()).
• even: Header and footer for even pages. Here, only chic-header(), chic-footer() and chic-separator() functions will take effect. Other functions must be given as an argument of chic().
• odd: Sets the header and footer for odd pages. Here, only chic-header(), chic-footer() and chic-separator() functions will take effect. Other functions must be given as an argument of chic().
• ..functions(): These are a variable number of arguments that corresponds to Chic-header’s style functions.

   • right-side: Content displayed in the right side of the footer (default is none).
3. chic-separator() - Sets the separator for either the header, the footer or both.

   • outset: Space around the separator beyond the page margins (default is 0pt).
   • gutter: How much spacing insert around the separator (default is 0.65em).

   • color: Separator’s color (default is black).
   • (unnamed): A string indicating the separator’s style. It can be "double-line", "center-dot", "bold-center", or "flower-end".
5. chic-height() - Sets the height of either the header, the footer or both.
   • on: Where to change the height. It can be "header", "footer" or "both" (default is "both").
   • (unnamed): A relative length (the new height value).
6. chic-offset() - Sets the offset of either the header, the footer or both (relative to the page content).

7. chic-page-number() - Returns the current page number. Useful for header and footer sides. It doesn’t take any parameters.
8. chic-heading-name() - Returns the next heading name in the dir direction. The heading must have a lower or equal level than level. If there’re no more headings in that direction, and fill is true, then headings are sought in the other direction.
   • dir: Direction for searching the next heading: "next" (from the current page, get the next heading) or "prev" (from the current page, get the previous heading). Default is "next".
   • fill: If there’s no more headings in the dir direction, indicates whether to try to get a heading in the opposite direction (default is false).
   • level: Up to what level of headings should this function search (default is 2).
