Free basic software for linux

BASIC-256 is an easy to use version of BASIC designed to teach young children the basics of computer programming. The BASIC-256 project uses traditional control structures like gosub, for/next, and goto, which helps kids easily see how program flow-control works.
It has a built-in graphics mode which lets them draw pictures on screen in minutes, and a set of detailed, easy-to-follow tutorials that introduce programming concepts through fun exercises.
BASIC-256 is licensed under the GNU public license, which means that its free to download, modify, and share.
Enhancements:
- Version 0.9.2 fixes some minor bugs, adds anonymous arrays and a sound command for Windows versions.
- Translations have been updated, and a command line option -l lets users select the language at run time.

MWChat Basic (My Web based Chat) is the free version of our online chat system.

Licenses are IP based, one license per IP.

It has support for multiple rooms and languages, a large number of IRC-like commands, private messages and rooms, message encryption, buddy lists, logging, registered users, chat profiles, file sharing, and more. It is a very lightweight, full-featured, and secure chat room.

Perl::Metric::Basic is a Perl module that can provide basic software metrics.

SYNOPSIS

# first construct a PPI::Document object to pass in
my $document = PPI::Document->load("t/lib/Acme.pm");

# then retrieve metrics on the document
my $m = Perl::Metric::Basic->new;
my $metric = $m->measure($document);

# $metric will consist of something like:
# Acme => {
# new => {
# blank_lines => 1,
# comments => 1,
# lines => 7,
# lines_of_code => 6,
# numbers => 0,
# numbers_unique => 0,
# operators => 3,
# operators_unique => 2,
# symbols => 5,
# symbols_unique => 2,
# words => 7,
# words_unique => 6
# },
# ...

When constructing software one often produces code of vastly differing quality. The Perl::Metric::Basic module leverages the PPI module to provide some interesting software metrics for Perl code, mostly measuring size and maintainability.

A metric is some sort of measurement which is intended to help you make a decision about a piece of code. There arent any hard rules about metrics, but the ones provided should allow you to make decisions about modules or subroutines which are outliers. Abnormal measurements in a subroutine are a warning sign that you should reexamine that routine, checking for unusually low quality.

This module uses the PPI module, and thus can parse Perl code without evaluating it.
If youre interested in software metrics, I highly recommend "Code Complete" (Second Edition) by Steve McConnel (Microsoft Press).

METHODS

new()

The new() method is the constructor:
my $m = Perl::Metric::Basic->new;

measure()

The measure() method measures some metrics and returns a hash reference. Files in Perl can contain more than one package, and it is interesting to seperate metrics by package. The key for the hash reference is the name of the package, and the value is another hash reference.

Perl packages are seperated into subroutines, and it is interesting to seperate metrics by subroutine. The key for the second hash reference is the name of the subroutine, and the value is another hash reference containing metrics.

There are various metrics applied to the subroutine. The key for the third hash reference is the name of the metric, and the value is the value of the metric. The metrics are:

blank_lines

The number of blank code lines.

comments

The number of lines containing comments.

lines

The total number of lines.

lines_of_code

The number of lines of code.

numbers

The total number of numbers used (eg "$z = 42 * 3" would have 2 numbers).

numbers_unique

The number of unique numbers used (eg "$z = 2*$x + 2*$y" would have 1 unique number).

operators

The total number of operators used.

operators_unique

The number of unique operators used.

symbols

The total number of symbols used (eg "$z = $x*$x + $y*$y" would have 5 symbols).

symbols_unique

The number of unique symbols used (eg "$z = $x*$x + $y*$y" would have 3 unique symbols).

words

The total number of words (operators) used.

words_unique

The number of unique words used.

CBM BASIC Lister is a Commodore related application to convert BASIC programs from their binary form to text.
CBM BASIC Lister (formerly C64 BASIC Lister) is a tool to generate an easily readable and printable BASIC listing of any CBM BASIC program (C64/VIC20, etc.) saved as "prg" file.
It is not a BASIC interpreter, its not a debugger and neither a development tool. Its just a LISTer and, by default, it acts just as the C64 native "LIST" command does.
Extra flow-control options were introduced to automatically correct the aspect of each listing and format it before introducing any part of it in your own electronic documents.
Of course, it can be used to study a BASIC program listing from your PC too.
Main features:
- Optional indent-ation of cycle (and procedure with Extended sets) body, with nested cycles processing
- Optional right alignment of BASIC line numbers
- Optional blank line insertion after a RETURN/END command (and End of procedures with Extended sets)
- Simons BASIC, Ultra BASIC (ABACUS), and Special BASIC support (with detection)

CGI::WeT::Modules::Basic is a basic rendering engine extensions.

SYNOPSIS

use CGI::WeT::Modules::Basic ();

This module provides basic rendering constructs for the engine. Please be aware that the code supersedes the documentation. While I have tried to be accurate there are times that words fail me and a look at the code is far more enlightening than anything I could cobble together. This is especially true when trying to write a theme. Download a theme and see how someone else did it. Then try making modifications and see what happens.

Language::Basic::Variable is a Perl module to handle parsing and implementing BASIC variables.

SYNOPSIS

See Language::Basic for the overview of how the Language::Basic module works. This pod page is more technical.
There are two sorts of variables: Arrays and Scalars. Each of those classes has a subclass for Numeric or String variables.

An Array needs to have full LBV::Scalar objects in it, rather than just having an array of values. The reason is that, for example, you might use ARR(3) as the variable in a FOR loop. Also, the "set" and "value" methods apply to a LBV::Scalar (since you cant set an array to a value (in BASIC) so in order to be handle A(3)=3, A(3) needs to be an LBV::Scalar.

The lookup method looks up a variable in the Array or Scalar lookup table (depending on whether there were parentheses after the variable name). BASIC allows undeclared variables, so if the variable name hasnt been seen before, a new variable is created.

Language::Basic::Variable::Scalar class

This class handles a variable or one cell in an array.

Methods include "value", which gets the variables value, and "set", which sets it.

Language::Basic::Variable::Array class

This class handles a BASIC array. Each cell in the array is a LBV::Scalar object.

Methods include "dimension", which dimensions the array to a given size (or a default size) and get_cell, which returns the LBV::Scalar object in a given array location.

Note that BASIC arrays start from 0!

Blackjack basic strategy calculator project is a Monte Carlo basic strategy calculator.
bsc finds the Blackjack strategy through the Monte Carlo method.
It analyzes each situation with adaptive depth, and is generally optimized for speed.
The rules are hard coded for the authors local casino; adding others or changing them is left for others to do.
It seems to find the correct strategy, but the house edge appears a bit wrong.
Main features:
- no double after split
- double only 9..11
- split as often as you want
- European no hole card
- no surrender
- dealer stands on soft 17
- perfect continous shuffle machine (CSM)
- 6 decks
