SLyDIFi is a package (class file) for creating slides with SATySFi . It is equivalent to beamer in LaTeX (only the minimum functions are available).

It can be installed using Satyrographos.
Concretely, you can install SLyDIFi with the following command:

opam install satysfi-class-slydifi
satyrographos install

If you want to check the operation to see if it was installed correctly, prepare minimum.saty with the following description under an appropriate directory:

@require: class-slydifi/theme/plain

document '<
  +frame{\SLyDIFi; のテスト}<
    +p{Hello, \SLyDIFi;!}
  >
>

If you run satysfi command and the following PDF is generated, it is working properly (please prepare the necessary fonts as appropriate).

Try it in Gitpod!

You can create PDF (example/plain.pdf) by editing example/plain.saty freely and run satysfi example/plain.saty on console. This demo uses pickoba/gitpod-satysfi and you can also install other packages via opam / satyrographos command.

SLyDIFi has the following functions.

In the standard slide theme, the following three types of slides are available.

• Normal slide
• Title slide
• Section slide

For the specific layout, refer to "Selecting and Changing Themes" below.

The following markup can be done in the frame.

• Paragraph
• Itemize (bullets)
• Insertion of figures
• Insertion of footnotes

In addition, the following commands are available as in-line text markup (it varies depending on the theme).

• \emph
• \link
• \text-color
• \uline
• \stroke

SLyDIFi supports multiple themes. At present, three types of themes are available as standard. You can create your own theme, or you can customize an existing theme yourself (although no documentation has been created for that).

The following is the appearance and introduction method of the theme prepared as standard.

A simple theme without decoration.

@require: class-slydifi/theme/plain

See here for further examples.

A theme based on the colors of Gruvbox .

@require: class-slydifi/theme/hakodate

See here for further examples.

To use this theme with default configuration, you need to install M + font and run the following command:

satyrographos install --system-font-prefix 'system:'

Note that the font settings can be changed freely in the document file.

Gray standard theme.

@require: class-slydifi/theme/akasaka

See here for further examples.

To use this theme with default configuration, you need to install Noto Sans font family (Noto Sans and Noto Sans CJK JP) and link it with a hash file.
Now it is already registered with Satyrographos and can be installed with the following command:

opam install satysfi-fonts-noto-sans
opam install satysfi-fonts-noto-sans-cjk-jp
satyrographos install

See SATySFi-fonts-noto-sans and SATySFi-fonts-noto-sans-cjk-jp for details.

And note that, the font settings can be changed freely, too.

A COOL theme based on the colors of iceberg.vim.

@require: class-slydifi/theme/arctic

See here for further examples.

Although the default settings require a IBM Plex Sans JP type font, you can change the font settings in the document file.

Arctic theme with Noto Sans.

@require: class-slydifi/theme/arctic-noto

See here for further examples.

This theme requires Noto Sans font family:

opam install satysfi-fonts-noto-sans
opam install satysfi-fonts-noto-sans-cjk-jp
satyrographos install

Each theme has a number of configurable parameters, which you can change on the document file. The main types of setting values that can be changed are as follows:

• font (font name, size, etc.)
• color (text color, background color, etc.)
• length (margin between paper border and footer, etc.)

For example, in the Akasaka theme, you can change settings such as the font size of the frame title and the background color of the slide as follows:

@require: class-slydifi/theme/akasaka

document '<

  +set-config(|
    SlydifiThemeAkasaka.default-config with  % 下に書いたフィールド以外はデフォルト値を使う
      font-frame-title = (fun ctx -> ctx |> SlydifiThemeAkasaka.default-config#font-frame-title |> set-font-size 20pt);
      color-bg = Color.of-css `lightcyan`;
      color-emph = Color.of-css `darkred`;
      length-frame-title-height = 28pt;
  |);

  +frame{フレーム}<
    ...
  >
>

@require: class-slydifi/theme/akasaka

document '<

  +set-config(|
    SlydifiThemeAkasaka.default-config with  % 下に書いたフィールド以外はデフォルト値を使う
      font-frame-title = (fun ctx -> ctx |> SlydifiThemeAkasaka.default-config#font-frame-title |> set-font-size 20pt);
      color-bg = Color.of-css `lightcyan`;
      color-emph = Color.of-css `darkred`;
      length-frame-title-height = 28pt;
  |);

  +frame{フレーム}<
