Intro

Instead of changing CSS style for Your Racket projects documentation, You may be interested in compiling Markdown files generated form Scribble source into HTML documentation website.

Creating MkDocs project

1. Create docs directory and mkdocs.yml config file in current directory, along with a dummy index.md file in docs folder.

   1	mkdocs new .

2. Edit the name of the project.

   Replace Racket-Project with your project name.

   1 2	--- site_name: Racket-Project

Building Scribble

Generate markdown files form scribble documentation.

Replace Racket-Project.scrbl with path to your scribble documentation main source file.

1

scribble --markdown --dest ./docs --dest-name index.md Racket-Project.scrbl

Building Markdown

Compile HTML documentation from the markdown source.

1

mkdocs build

HTML files should appear in the site directory.

Running the server

Some features, like search for example are only available when running the mkdocs server.

1

mkdocs serve

Caveats

Some scribble functions do not look good or work correctly for markdown-to-HTML compilation by MkDocs.

• table-of-contents - looks like a source block

• index-section - letter links do not work

Creating binaries

You can create portable binaries with Racket's raco command! Use raco exe and raco distribute.

More -> https://docs.racket-lang.org/raco/exe.html

Sample games

Racket provides a executable plt-games, when ran (from console) it opens a menu of miscellaneous games, among them: jewel, minesweeper, aces, spider, checkers. & more (20 games total).

Plots

You can plot data in 2d & 3d forms.

2D

Sample code:

1

#lang racket/base
(require racket/gui/base racket/math plot)

(plot-new-window? #true)

(plot (function sin (- pi) pi #:label "y = sin(x)"))

3D

#lang racket/base
(require racket/gui/base racket/math plot)

(plot-new-window? #true)

(plot3d
 (surface3d (lambda (x y) (* (cos x) (sin y)))
            (- pi) pi (- pi) pi)
 #:title "An R × R → R function"
 #:x-label "x" #:y-label "y" #:z-label "cos(x) sin(y)")

Browser

There's a included library to render web pages, just "(require browser)".

Sample code:

#lang racket
(require browser)

(open-url "https://xgqt.gitlab.io/")

FFI

You can use Racket's Foreign Function Interface to interact with non-Racket libraries to make use of very fast libraries written in (mainly) FORTRAN & C.

For example sci uses FFI for CBLAS & LAPACK.

Parallelism

For greater speed up with parallel execution there are futures, places and distributed places (for distributed programming).
