typst-font-compare

A tool to compare how Typst documents would look using different fonts or font variants.

Installation

cargo install --path .

Usage

Examples

The following command generates a file main.variants.pdf containing all the system fonts:

typst-font-compare main.typ

To additionally check all variants, meaning style, weight, and stretch:

typst-font-compare --variants main.typ

The variants file includes too many Noto fonts. Let's remove them.

typst-font-compare --exclude Noto main.typ

We only want to compare a certain few fonts.

typst-font-compare --include 'Roboto|Inter|Ubuntu' main.typ

Only compare fonts that support italics.

typst-font-compare --style italic main.typ

Questions and Answers

The pages are much larger than necessary.

Prefix your document with the following snippet to make them be only as large as needed:

#set page(height: auto, margin: .5cm)

You can also use this one to automatically scale all dimensions, though it can sometimes produce subpar results:

#set page(width: auto, height: auto, margin: .5cm)

Why do certain fonts not appear?

This tool does not embed any fonts that might normally be embedded into Typst.
You must either install them system-wide, or add a --font-path fonts-folder argument, where fonts-folder contains the needed fonts.

The generated document looks weird in my PDF viewer.

Each page this tool generates can have a different height.
Some PDF viewers don't handle this correctly.
Try opening the file in Firefox instead.

I'm getting a file not found error when including a package.

This tool does not automatically download packages.
Compile your document using typst compile first and then typst-font-compare should work correctly.

The program just crashes at some point.

Images are stored in memory, making it potentially very memory intensive.
Thus, your OOM killer (out-of-memory killer) shuts it down.
Try not generating each variant, excluding certain fonts, or decreasing the PPI.
