PDF Skill

Create, read, and edit PDFs using CLI tools.

Core Workflow — Creating PDFs

Every PDF creation follows this pattern:

1. Write a .typ file using write_file
2. Compile with typst compile input.typ output.pdf
3. Send with send_file

Minimal Example

typstCopy code
#set page(paper: "us-letter", margin: 1in)
#set text(font: "New Computer Modern", size: 11pt)

= My Report

This is a paragraph with *bold* and _italic_ text.

- First item
- Second item

#table(
  columns: (1fr, 1fr, 1fr),
  [*Name*], [*Role*], [*Status*],
  [Alice], [Engineer], [Active],
  [Bob], [Designer], [Active],
)

Save as report.typ, then:

bashCopy code
typst compile report.typ report.pdf

Essential Typst Syntax

Text Formatting

typstCopy code
*bold*          _italic_          `monospace`
#underline[underlined]            #strike[struck]
#smallcaps[Small Caps]            #super[sup]  #sub[sub]
#text(fill: blue)[colored text]   #text(size: 14pt)[larger]

Headings

typstCopy code
= Level 1
== Level 2
=== Level 3

To number headings:

typstCopy code
#set heading(numbering: "1.1")

Lists

typstCopy code
- Bullet item
  - Nested item
- Another item

+ Numbered item
+ Another numbered item

/ Term: Definition
/ Another: Its definition

Tables

typstCopy code
#table(
  columns: (auto, 1fr, 1fr),
  align: (left, center, right),
  table.header([*Col A*], [*Col B*], [*Col C*]),
  [Row 1A], [Row 1B], [Row 1C],
  [Row 2A], [Row 2B], [Row 2C],
)

Images

typstCopy code
#image("photo.jpg", width: 50%)

#figure(
  image("chart.png", width: 80%),
  caption: [Monthly revenue growth],
)

Links

typstCopy code
#link("https://example.com")[Click here]

Page Breaks

typstCopy code
#pagebreak()

Math

Inline: $x^2 + y^2 = z^2$

Display:

typstCopy code
$ sum_(i=1)^n i = (n(n+1)) / 2 $

Horizontal Rule

typstCopy code
#line(length: 100%, stroke: 0.5pt + gray)

Font Selection

Serif (reports, letters, academic):

typstCopy code
#set text(font: "New Computer Modern", size: 11pt)

Sans-serif (modern, presentations):

typstCopy code
#set text(font: "Helvetica Neue", size: 11pt)

List available fonts:

bashCopy code
typst fonts

Page Layout

Margins and Paper Size

typstCopy code
#set page(
  paper: "us-letter",  // or "a4"
  margin: (top: 1in, bottom: 1in, left: 1in, right: 1in),
)

Headers and Footers

typstCopy code
#set page(
  header: context {
    if counter(page).get().first() > 1 [
      _My Document_ #h(1fr) #datetime.today().display("[month repr:long] [day], [year]")
      #line(length: 100%, stroke: 0.5pt + gray)
    ]
  },
  footer: context {
    let pg = counter(page).get().first()
    if pg > 1 [
      #h(1fr) #pg #h(1fr)
    ]
  },
)

Multi-Column

typstCopy code
#columns(2, gutter: 12pt)[
  Left column content...
  #colbreak()
  Right column content...
]

Color and Styling

Accent Colors

typstCopy code
#let accent = rgb("#2563EB")  // Professional blue

#show heading.where(level: 1): set text(fill: accent)
#show heading.where(level: 2): set text(fill: accent.darken(20%))

Callout Box

typstCopy code
#block(
  fill: rgb("#EFF6FF"),
  stroke: rgb("#2563EB") + 1pt,
  inset: 12pt,
  radius: 4pt,
  width: 100%,
)[
  *Note:* This is a highlighted callout box.

Quick Document Patterns

Report

typstCopy code
#set page(paper: "us-letter", margin: 1in)
#set text(font: "New Computer Modern", size: 11pt)
#set heading(numbering: "1.1")
#let accent = rgb("#2563EB")
#show heading.where(level: 1): set text(fill: accent)

#align(center)[
  #text(size: 24pt, weight: "bold")[Report Title]
  #v(8pt)
  #text(size: 12pt, fill: gray)[Author Name — #datetime.today().display("[month repr:long] [day], [year]")]
]
#v(1em)

#outline(title: "Contents", indent: auto)
#pagebreak()

Table-Heavy Document

typstCopy code
#set page(paper: "us-letter", margin: 0.75in)
#set text(font: "Helvetica Neue", size: 10pt)
#let accent = rgb("#2563EB")

#table(
  columns: (2fr, 1fr, 1fr, 1fr),
  fill: (_, row) => if row == 0 { accent } else if calc.odd(row) { luma(245) },
  table.header(
    ..([*Item*], [*Qty*], [*Price*], [*Total*]).map(c => text(fill: white, c))
  ),
  [Widget A], [10], [$5.00], [$50.00],
  [Widget B], [25], [$3.50], [$87.50],
  [Widget C], [5], [$12.00], [$60.00],
)

Reading PDFs

Requires poppler-utils (brew install poppler / apt install poppler-utils).

Extract Text

bashCopy code
pdftotext input.pdf -              # to stdout
pdftotext input.pdf output.txt     # to file
pdftotext -layout input.pdf -      # preserve layout
pdftotext -f 2 -l 5 input.pdf -   # pages 2-5

Get PDF Info

bashCopy code
pdfinfo input.pdf                  # metadata, page count, size

If pdftotext is not installed, tell the user and offer to install it.

Note: Scanned PDFs (image-only) will produce empty output from pdftotext. OCR requires additional tools.

Editing PDFs

Requires qpdf (brew install qpdf / apt install qpdf).

Merge

bashCopy code
qpdf --empty --pages file1.pdf file2.pdf file3.pdf -- merged.pdf

Split / Extract Pages

bashCopy code
qpdf input.pdf --pages . 1-5 -- first-five.pdf
qpdf input.pdf --pages . 3,7,12 -- selected.pdf

Rotate

bashCopy code
qpdf input.pdf --rotate=+90:1-5 -- rotated.pdf    # rotate pages 1-5

Encrypt

bashCopy code
qpdf --encrypt userpass ownerpass 256 -- input.pdf encrypted.pdf

Decrypt

bashCopy code
qpdf --password=ownerpass --decrypt input.pdf decrypted.pdf

If qpdf is not installed, tell the user and offer to install it.
