Typst as lib
Small wrapper around Typst that makes it easier to use it as a templating engine. This API is currently not really stable, although I try to implement the features with as little change to the API as possible.
Usage
rust code
// main.rs
static TEMPLATE_FILE: &str = include_str!("./templates/template.typ");
static FONT: &[u8] = include_bytes!("./fonts/texgyrecursor-regular.otf");
static OUTPUT: &str = "./examples/output.pdf";
static IMAGE: &[u8] = include_bytes!("./templates/images/typst.png");
fn main() {
let font = Font::new(Bytes::from(FONT), 0).expect("Could not parse font!");
// Read in fonts and the main source file.
// We can use this template more than once, if needed (Possibly
// with different input each time).
let template = TypstTemplate::new(vec![font], TEMPLATE_FILE);
let mut tracer = Tracer::new();
// Run it
// Run `template.compile(&mut tracer)` to run typst script
// without any input.
let doc = template
.compile_with_input(&mut tracer, dummy_data())
.expect("typst::compile() returned an error!");
// Create pdf
let pdf = typst_pdf::pdf(&doc, Smart::Auto, None);
fs::write(OUTPUT, pdf).expect("Could not write pdf.");
}
Typst code
// template.typ
#import sys: inputs
#set page(paper: "a4")
#set text(font: "TeX Gyre Cursor", 11pt)
#let content = inputs.v
#let last_index = content.len() - 1
#for (i, elem) in content.enumerate() [
== #elem.heading
Text: #elem.text \
Num1: #elem.num1 \
Num2: #elem.num2 \
#if elem.image != none [#image.decode(elem.image, height: 40pt)]
#if i < last_index [
#pagebreak()
]
]
Run example with:
cargo r --example=small_example
Resolving files
Binaries
Use TypstTemplate::with_static_file_resolver
and add the binaries as key value pairs ((file_name, &[u8])
).
Sources
Use TypstTemplate::with_static_source_file_resolver
and add the sources as key value pairs ((file_name, String)
).
Local files
Resolving local files can be enabled with TypstTemplate::with_file_system_resolver
. The root should be the template folder. Files cannot be resolved, if they are outside of root.
Can be enabled like this:
let template = TypstTemplate::new(vec![font], TEMPLATE_FILE)
.with_file_system_resolver("./examples/templates");
If you want to use another local package install path, use:
let template = TypstTemplate::new(vec![font], TEMPLATE_FILE)
.add_file_resolver(
FileSystemResolver::new("./examples/templates")
.with_local_package_root("local/packages")
);
Remote Packages
The package
feature needs to be enabled.
Can be enabled like this:
let template = TypstTemplate::new(vec![font], TEMPLATE_FILE)
.with_package_file_resolver(None);
This uses the file system as a cache.
If you want to use another cache root path, use:
let template = TypstTemplate::new(vec![font], TEMPLATE_FILE)
.add_file_resolver(PackageResolver::new(
PackageResolverCache::FileSystem(Some("cache/root")), None
));
If you want to instead use the memory as cache, use:
let template = TypstTemplate::new(vec![font], TEMPLATE_FILE)
.add_file_resolver(PackageResolver::new(
PackageResolverCache::Memory(Default::default()), None
));
Examples
Static binaries and sources
See example which uses the static file resolvers.
cargo r --example=resolve_static
Local files and remote packages
See example which uses the file and the package resolver.
cargo r --example=resolve_files --features=package
Custom file resolver
You can also write your own file resolver. You need to implement the Trait FileResolver
and pass it to the TypstTemplate::add_file_resolver
function.
TypstTemplateCollection
If you want to compile multiple typst (main) source files you might want to use the TypstTemplateCollection
, which allows you to specify the source file, when calling TypstTemplateCollection::compile
, instead of passing it to new. The source file has to be added with TypstTemplateCollection::add_static_file_resolver
first.
TypstTemplate
is just a wrapper around TypstTemplateCollection
, that also saves a FileId
for the main source file.
Loading fonts
Loading fonts is not in the scope of this library (yet?). If you are interested in that, write an issue.
TODO
- allow usage of reqwest instead of ureq with a feature flag
- fonts
