Paper terminal

dependency status

See paper.png to see what this looks like!

Writes a file to a paper in your terminal. Especially if that file is Markdown! Features supported include:

  1. The usual text, and paragraphs with automatic line-wrapping. You can manually wrap with
    hard breaks as expected.

    Otherwise, paragraphs will be nicely spaced.

  2. Headings

  3. Bold / Italic / Bold and Italic / Strikethrough

  4. Lists

    • Ordered
    • Unordered
      • Nested
  5. Rules

  6. Inline code

  7. Code blocks, with syncat integration for syntax highlighting. Note that you must install syncat and make the syncat executable available on your path for this to work.

    fn main() {
        println!("Hello world");
    }
    
  8. Blockquotes

    Blockquotes

    And even nested block quotes

  9. And even images! Here's a photo of my cat

    My cat. His name is Cato

  10. Task lists:

    • Easy
    • Hard
  11. Footnotes[^ft]

    [^ft]: This is the footnote!

  12. Tables

Comparison with other command line Markdown renderers

Not a very good comparison... this is more of an example of a table!

Styling

Paper uses syncat stylesheets to allow full customization of styling. See the default stylesheet (src/default.syncat) as an example of how this works. To override the default styles, create paper.syncat in your active syncat theme.

  • Different scopes are represented as nodes, inspired by the corresponding HTML tag names.

    • h1 through h6
    • strong
    • emphasis
    • strikethrough
    • code
    • blockquote
    • ul, ol, li
    • footnote-ref, footnote-def, footnote
    • table
    • caption
    • link
  • The paper and shadow can be matched with paper and shadow. Styles applied to paper are applied to everything.

  • The "prefix" and "suffix" tokens can be used to match the decorations

    • List item bullets
    • Blockquote markers
    • Code block margins
  • The "lang-tag" token matches the language name written in the bottom corner of the code block

  • You can apply styles to code blocks with a specific language by using the language name as the token

For now, the prefix/suffix contents are not customizable, but this may be added in future if it is desired.

Paper can be installed from crates.io using Cargo:
