Quickstart

This walkthrough takes you from an empty folder to a rendered PDF.

1. Write a report

Create a file called report.yml. The top-level keys are your headings, and their values are the content underneath them.

Site inspection report:
  - >
    This is the first paragraph. The `>` character tells YAML you are entering a
    multi-line string that should be word-wrapped. Leave a blank line to start a new
    paragraph.
  - Findings:
    - Bullets:
      - The handrail is loose on the north stair.
      - Two ceiling tiles are water-stained in the lobby.
    - Items observed:
      - Item Number: 12.01
        Description: There is a problem here. This report documents it.
        Location: Under the stairs
      - Item Number: 12.02
        Description: Five ladybugs on the table cloth.
        Location: Kitchen

A few things are happening here:

  • Site inspection report: is the document heading (an <h1>).

  • Each - under it is a list item rendered in document order.

  • Findings: is a nested sub-heading, because it is a key whose value is more content.

  • Bullets: renders a bulleted list; Items observed: renders a table because each list item is a mapping (the keys become column headers).

See Document structure for the full set of rules.

2. Render it

ym convert report.yml

✍️ .... 📝 ... PDF created: /path/to/report.pdf

By default the PDF is written next to the source file with a .pdf extension. To choose a destination:

ym convert report.yml output/inspection.pdf

3. Iterate live (optional)

While drafting, run ym live to open the PDF and rebuild it automatically every time you save:

ym live report.yml

Leave it running in a terminal, edit report.yml in your editor, and the preview refreshes on save. Press Ctrl+C to stop.

4. Style it

Add configuration keys prefixed with an underscore at the top of the file. For example, to change the body font and heading colour:

_style:
  body:
    font: NotoSans
  headings:
    font: AppleGaramond
    color: "#dd9922"

Site inspection report:
  - >
    Everything below inherits the styles above.

Configuration can live inline (as above) or in a shared project config file so several documents look alike. See Configuration.

5. Add richer content

When plain prose isn’t enough, reach for a block — a key that starts with an underscore and expands into custom content:

Report:
  - Photos:
    _img:
      src: site.png
      caption: "Figure 1: The north stairwell"
      scale_ratio: 0.5
  - _info: Remember to file this report by end of week.
  - _pagebreak:

The full catalogue is in the Blocks reference.
