// the markdown source rendered as the body of this sheet
#let md-source = "tp1.md"

// set to `false` to drop the first page with the table of contents
#let show-toc = true

// ---------------------------------------------------------------- styles ----

#show figure.caption: set text(size: 0.9em, fill: luma(70))

// the outline picks up the headings cmarker emits further down
#show outline.entry.where(level: 2): set text(weight: "semibold")

// each `##` heading starts on a fresh page, except the first one, which stays
// on the title page — `weak` avoids a blank page when we are already at the top
#let md-section = counter("md-section")
#show heading.where(level: 2, outlined: true): it => {
  context if md-section.get().first() > 0 {
    pagebreak(weak: true)
  }

// ------------------------------------------------------------------ math ----

// hugo goldmark delimits math with `\(...\)` and `\[...\]`, while cmarker
// expects the typst/markdown `$...$` and `$$...$$` forms
#let goldmark-math(markdown) = {
  markdown
    .replace("\\[", "$$")
    .replace("\\]", "$$")
    .replace("\\(", "$")
    .replace("\\)", "$")
}

// ---------------------------------------------------------------- images ----

// maximum footprint of an image coming from the markdown source
#let img-max-height = 6cm
// set to `none` to drop the frame around screenshots
#let img-stroke = 0.5pt + luma(180)

// scale an image down so it fits both the available width and `img-max-height`,
// without ever blowing it up past its natural size
#let fitted-image(source, ..args) = layout(available => {
  let natural = measure(image(source, ..args))
  let factor = calc.min(
    1.0,
    available.width / natural.width,
    img-max-height / natural.height,
  )
  image(source, width: natural.width * factor, ..args)
})

// handle `![alt](src)` and `<img src=... width=... height=...>`
#let md-image(source, alt: none, width: auto, height: auto, ..args) = {
  // an explicit width/height in the markdown wins over the automatic fitting
  let body = if width == auto and height == auto {
    fitted-image(source, alt: alt, ..args)
  } else {
    image(source, alt: alt, width: width, height: height, ..args)
  }

  let framed = block(stroke: img-stroke, radius: 3pt, clip: true, body)

  // alt text, when there is one, becomes a numbered caption
  if alt == none or alt == "" {
    align(center, framed)
  } else {
    figure(framed, caption: alt)
  }
}

// ------------------------------------------------------------------- toc ----

// outline's own title is a level-1 heading, which would outrank every heading in
// the source (they start at `##`), so we emit it ourselves at the right level
#if show-toc {
  heading(level: 2, outlined: false)[Sommaire]
  outline(title: none, depth: 3, indent: 1em)
  pagebreak()
