A customizable Typst letter template with some presets for DIN 5008 A/B and Swiss C5 Letter. Please note that the template is still under development and subject to breaking changes.

See the examples

• lttr-init is responsible to compute all values from the parameters and default values for different formats. It also sets the page and text attributes.

• lttr-preamble renders:

  • lttr-sender
  • lttr-receiver
  • lttr-indicator-lines
  • lttr-content-offset
  • lttr-horizontal-table
  • lttr-date-place
  • lttr-title
  • lttr-opening

• lttr-closing renders the closing line and the signature.

All Parameters are optional and will override the global defaults and the defaults of the chosen format. Some of them allow to either specify the content directly or use a dict if other settings need to be changed also. For example: receiver: "x" is the same as receiver: (content: "x").

Currently, I just create a symlink such that I can import it with #import "@local/lttr:0.1.0": * as follows.

mkdir -p ${XDG_DATA_HOME}/typst/packages/local/lttr/
ln -s /path/to/this/repo ${XDG_DATA_HOME}/typst/packages/local/lttr/0.1.0

While there exists a first version of typst packages, they do not yet accept custom templates (afaik). For the meantime, you can download and extract the release tarball to ${XDG_DATA_HOME}/typst/packages/local/lttr/<version> and import it as described in Development Setup.

There are a couple of limitations in typst which I hope will be addressed.

• There is currently no way to query properties set with set. This would be nice to query the document title and author names issue. Forthermore, it is not possible to call set after the first lttr function has been called (even if no content was rendered added).
• datetime with locales settings

Other things:

• Add more layouts including (us letter, ?)
• Vertical table for sender field as for example here
• Maybe add lines with labels to display measurements/sizes in debug mode
• Add this to the typst preview packages. Currently, they apparently do not accept packages.
