einfart : write you articles in a simple and clear way

New documentations are still being written. For now, only the core code is included in Live 2023 (old documentations have been removed from the distribution).

einfart is a class for typesetting articles, which has a simple and clear design.

Currently, it has native support to Chinese (simplified and traditional), English, French, German, Italian, Japanese, Portuguese (European and Brazilian), Russian and Spanish typesetting. And it may compile with either XeLaTeX or Lua.

This is part of the minimalist class series.

Features

Compared with usual document classes, it has the following features:

  • Several carefully designed styles.
  • Native multilingual support: Chinese (simplified and traditional), English, French, German, Italian, Japanese, Portuguese (European and Brazilian), Russian and Spanish.
  • In particular, for simplified Chinese, traditional Chinese and Japanese, the fonts of the corresponding glyphs can be automatically switched.
  • Ready-to-use theorem-type environments, with clever referencing supported.
  • Support both the standard and the AMS writing fashion.
  • ... and much more...

Required fonts

The current document class requires the following open-source fonts that are not included in the standard collection:

Improvements to the current font configuration

The code in this section is rather experimental and may constantly get changed. The author uses these lines of code in his daily documents, but since it involves non-free fonts and/or uses complex Lua patches, the code below cannot be integrated into the published version.

If you are willing to use Lua, then the following aspects may help you further improve the current font configuration.

  • If you have the font Palatino Linotype installed, then replacing the default TeXGyrePagellaX using the following code gives you slightly better result:
  •   \directlua
        {
          fonts.handlers.otf.addfeature
            {
              name = "palatino-linotype-fix",
              type = "kern",
              data =
                {
                  ["r"] = { ["ê"] = 120 },
                  ["v"] = { ["ê"] = 180 },
                  ["w"] = { ["ê"] = 180 },
                  ["y"] = { ["ê"] = 180 },
                },
            }
        }
      \setmainfont{Palatino Linotype}
        [
          Numbers = OldStyle ,
          RawFeature = +palatino-linotype-fix
        ]
      
  • If you have the font Palatino Sans LT Pro installed, then replacing the default mathsf font with this gives more pleasant visual effect:
  • \setmathsf{Palatino Sans LT Pro}
    \setmathfont{PalatinoSansLTPro-LightIta}[range=sfit]
    
  • The default configuration for math fonts has some imperfections. The following code helps to improve it. But for this you need to modify the .cls file itself and then maintain your local version of it. Here is how:
    • First, add this definition at the beginning of the font configuration.

einfart – Write your articles in a simple and clear way

This package provides a class for typesetting articles with a simple and clear design.

Currently, it has native support for Chinese (simplified and traditional), English, French, German, Italian, Japanese, Portuguese (European and Brazilian), Russian and Spanish typesetting. It compiles with either XeLaTeX or Lua.

This is part of the minimalist class series and depends on minimalist.sty from the minimalist package.

The package name “einfart” is taken from the German word “einfach” (“simple”), combined with the first three letters of “Artikel” (“article”).
