Ruby

Local mirror

Mirror of the latest stable Ruby sources.

httpd: 1.8 development release by Patric Mueller.
httpd-1.6 1.6 stable
httpd-1.6.1.6: 1.7 development release
ChangeLog

A simple http daemon for local use, supports CGI scripts.

Realtime on Rails:

With this rails application, it is possible to stream content and commands from a server to connected browsers. Contains a push server based on httpd

deb 0.4

Interactive front-end to depends, apt and dpkg for frequently used functions. Uses readline for package-name completion. Can easily be extended with more commands.

depends 1.5 - ChangeLog

A tool to determine the reverse dependencies of a Debian package, i.e., what packages depend on a certain package. Provides Package, Dependency, (Package)Pool and Cache classes.

mem 1.6

Memory monitor for linux kernels >= 2.4.18. Shows /proc/meminfo in tabular form at configurable intervals, somewhat like vmstat but focused on the details of linux memory management.

semaphore

A generic multi-value Semaphore class with wait, signal and synchronize methods.

ruby.vim 0.5

Updated for Ruby 1.6. Vim syntax coloring file for Ruby, needs some more work. Vim versions 5.7+ and 6.0+ have a ruby.vim in the distribution.

Miscellaneous conceptual scripts

3darray: 3-dimensional array class

any-all: existential and all-quantor for Enumerable

array-default: change default fill value for Array

composite: composite + visitor GoF patterns (other patterns to come)

dbc: Design By Contract try-out

dispatcher: dispatch to class methods based on text input

extend: 2 different uses of the extend keyword

function: math-like function notation

generators: generating a Fibonacci sequence using continuations (glarked from ruby-talk)

haskell: adds Haskell list operations to Array (head, last, tail, foldl, scanl, take, drop, take_while, zip etc., fairly incomplete)

interface: simple interface pattern

interface-abstract: interface pattern using `abstract :method' notation

lruby: simple-minded literate Ruby

mime: mime types abstraction

net-clnt + net-svr: basic TCP/IP client and server pair

pipe: uni/bi-directional pipe handling

reduce: a generalized inject function

remove_class: removing a class definition with remove_const

sorts: quicksort, mergesort, insertionsort, bubblesort (from the Ruby Cookbook?)

static-typed: proof of concept for static typed attributes and methods (incomplete)

symbolic: Symbolic derivation. Ruby variant of the LISP program in Structure and Interpretation of Computer Programs, section 2.3.2.

unowned: lists files that are not owned by any Debian package

version_compare: compare alpha-numeric version strings like '0.1a-9.5.4', '1.2-alpha+1-2' and weirder

xml: generic XML generation function

Scheme

gauche-mode.el, requires r5rs.el.

GNU Emacs major mode for Gauche scheme. Provides gauche syntax for indentation and font-lock, info lookup (gauche and R5RS), buffer-evaluation, and key bindings.

stklos-mode.el, requires r5rs.el.

GNU Emacs major mode for STklos scheme.

rep-mode.el.

GNU Emacs major mode for librep.

Scheme code collections:

Gauche Scheme code collection.

librep Scheme/Lisp hybrid code collection.

C/C++ projects

x3d 0.1.1 - screenshot

Interactive 3D-viewing of vector objects. Does hidden line removal and dynamic lighting wrt. a point light source. Implemented using the ax class lattice.
Archive includes:

• ax library
  Simple X Window System abstraction layer. Provides abstractions like axWindow, axEvent, axException, axObject, axVector (class template for dynamically sized vectors a la Java). axWindowDBE is a Double Buffer Extension window class for animations.
• matrix library
  Matrix and vector classes; implements frequently used operations like vector crossproduct, vector dotproduct, and matrix rotation, inversion and determinant.

xgrav 0.1 - screenshot

Simulation of the chaotic behaviour of 3 point masses (planets, moons), moving through 2D-space ruled by Newton's law of gravitation: Orbits are approximated using small, discrete time-steps. The simulation could be made more precise using differential calculus.

Music: L'Equipe Orpheus

The Orpheus Equipe is a collective of three people going wild on free-jazz*. The music is disorganized into a kind of rock-opera's, improvised from start to end. This is our seventh album, noting that the titles are tentative (as is the music).

Be warned that this is highly experimental music, though no musical instruments were harmed during its creation. CD's are available at material + shipping cost. Mail us.

More free Orpheus Equipe stuff and some flabbergasting artwork is now available!

* `free' as in `free speech', and `free beer'.

Episode VII : The Stereo Sessions

1. Biddybiddybiddy heybuck
2. Andalligotwhasthislousyt-bird
3. Walking the frog
4. Basscamp 6
5. Flowers of dub
6. Laminanimal
