The simple-siam Typst package

A Typst template for SIAM paper submissions

About the name

• typst-simple-siam is the name of the GitHub repo, simple-siam is the name of the Typst template
• The Typst template name does not contain typst, because it is redundant¹
• The Typst template name is not just siam, because it is not an official template, thus the name must start with a non-descriptive part¹

Template adaptation checklist

• Fill out README.md
  • Change the my-package package name, including code snippets
  • Check section contents and/or delete sections that don't apply
• Check and/or replace LICENSE by something that suits your needs
• Fill out typst.toml
  • See also the typst/packages README
• Adapt Repository URLs in CHANGELOG.md
  • Consider only committing that file with your first release, or removing the "Initial Release" part in the beginning
• Adapt or deactivate the release workflow in .github/workflows/release.yml

  • to deactivate it, delete that file or remove/comment out lines 2-4 (on: and following)

  • to use the workflow

    • check the values under env:, particularly REGISTRY_REPO
    • if you don't have one, create a fine-grained personal access token with only Contents permission for the REGISTRY_REPO
    • on this repo, create a secret REGISTRY_TOKEN (at https://github.com/[user]/[repo]/settings/secrets/actions) that contains the so created token

    if configured correctly, whenever you create a tag v..., your package will be pushed onto a branch on the REGISTRY_REPO, from which you can then create a pull request against typst/packages

• remove/replace the example test case
• (add your actual code, docs and tests)
• remove this section from the README

Getting Started

Important

This template is not published yet, you cannot access it from @preview/, but you can download src/lib.typ and use it in your project.

From the CLI:

typst init @preview/simple-siam

From the Typst web app:

#import "@preview/simple-siam:0.1.0": conf

#show: doc => conf(
  title: [A Typst template for SIAM paper submissions],
  authors: [Sébastien Mestrallet],
  abstract: [See #link("https://github.com/sebmestrallet/typst-simple-siam")],
  doc,
)

= First section

#lorem(50)

Theorems & algorithms

Based on third-party Typst packages, this template allows to insert formatted theorem/proof/definition/lemma environments, as well as algorithms:

#import "lib.typ": conf, theorem, definition, lemma, thmrules, proof, pseudocode-list, algorithm
#show: thmrules

#show: doc => conf(
  title: [A Typst template for SIAM paper submissions],
  authors: [Sébastien Mestrallet],
  abstract: [See #link("https://github.com/sebmestrallet/typst-simple-siam")],
  doc,
)

= A theorem

#theorem[
  Here the theorem formulation
]

= An algorithm

#algorithm(
  pseudocode-list(
    numbered-title: #smallcaps[(My Algorithm)],
    stroke: none,
    booktabs: false,
    indentation: 2em
  )[
    - *Require:* Some input $a$
    - *Require:* Some input $b$
    + Here the algorithm definition
  ]
)

Files

• src/lib.typ: provide the conf(title,authors,abstract,doc) function to format a paper
• src/main.typ: use conf() to reproduce the outputs of ltexpprt_anonymous-submission.tex & ltexpprt_accepted-submission.tex from the official template
• src/bib.yml: transcoding of ltexpprt_references.bib from the official template to the Hayagriva format
• src/siam.csl: Citation Style Language for the bibliography, based on the IEEE one (modified <macro name="author"> to have small caps)

Dependencies

• ctheorems (sahasatvik/typst-theorems) for numbered theorem environments, by Satvik Saha, Rory Molinari, Michael Hutchinson and DVDTSB [MIT]
• lovelace (andreasKroepelin/lovelace) for pseudocode, by Andreas Kröpelin and contributors [MIT]

They are imported with #import "@preview/{name}:{version} in src/lib.typ.

• The motivation and recommended interface for templates in the official tutorial
• The in-depth format requirements in the typst/packages README
• Do as the templates directly maintained by the Typst team
• Use the typst-package-template GitHub template from @typst-community
