Free chemistry dictionary software for linux

Homemade Dictionary is a customizable and easy to use dictionary, with features including background music support.
Homemade Dictionary has a built in "Test Your Word Power Game", a medical dictionary, and a nice GUI.
The dictionary has an initial database of of around 5600 words, including slang. You can add your personal words on the fly. It is very small in size (only 637 KB).
Enhancements:
- Wordlist has been updated

Sunrise Data Dictionary is a library for hashtable storage of arbitrary data objects with built-in reference counting and guaranteed order iteration for the C programming language.
Sunrise Data Dictionary library can participate in external reference counting systems or use its own built-in reference counting. It comes with a variety of hash functions and allows the use of runtime supplied hash functions via callback mechanism. The source code is well documented.
The Sunrise Data Dictionary was specifically designed for use within the Afelio and Callweaver telephony servers, the implementation focuses on performance and scalability.
Enhancements:
- This is the initial release of the full API (all header files) and a developer snapshot of the implementation.

EnRus dictionary tools project is a set of Tcl/Tk scripts for manipulating textual (plain or gzipped) dictionary base.
Its also used for compiling new dictionary bases from plain text files.
It consists of a few TCL console scripts and a Tk interface to them.
It is configurable for different languages.
The dictionary base may contain proper formatting and output procedures.
Main features:
- Find tool - finds records starting with exact pattern.
- Look tool - looks for words, starting with pattern.
- View tool - lets you to view all records that start with words starting with pattern.
- Search tool - searchs in dictionary base for records that answer to request.
- Guess tool - tries to guess words similar to pattern.
- Wander tool - returns random word (records) from file (WANDERWORDS in dictionary base directory or .enruswords in $HOME).
Enhancements:
- Default settings changed for working with Tk 8.3.

RADIUS::Dictionary is a RADIUS dictionary parser.

SYNOPSIS

use RADIUS::Dictionary;

my $dict = new RADIUS::Dictionary "/etc/radius/dictionary";
$dict->readdict("/some/other/file");
my $num = $dict->attr_num(User-Name);
my $name = $dict->attr_name(1);

This is a simple module that reads a RADIUS dictionary file and parses it, allowing conversion between dictionary names and numbers.

METHODS

new

Returns a new instance of a RADIUS::Dictionary object. If given an (optional) filename, it calls readdict for you.

->readdict

Parses a dictionary file and learns the namenumber mappings.

->attr_num($attrname)

Returns the number of the named attribute.

->attr_type($attrname)

Returns the type (string, integer, ipaddr, or time) of the named attribute.

->attr_name($attrnum)

Returns the name of the attribute with the given number.

->attr_numtype($attrnum)

Returns the type of the attribute with the given number.

->attr_has_val($attrnum)

Returns a true or false value, depending on whether or not the numbered attribute has any known value constants.

->val_has_name($attrnum)

Alternate (bad) name for attr_has_val.

->val_num($attrnum, $valname)

Returns the number of the named value for the attribute number supplied.

->val_name

Returns the name of the numbered value for the attribute number supplied.

Chemistry::Mol is a molecule object toolkit.

SYNOPSIS

use Chemistry::Mol;

$mol = Chemistry::Mol->new(id => "mol_id", name => "my molecule");
$c = $mol->new_atom(symbol => "C", coords => [0,0,0]);
$o = $mol->new_atom(symbol => "O", coords => [0,0,1.23]);
$mol->new_bond(atoms => [$c, $o], order => 3);

print $mol->print;

This package, along with Chemistry::Atom and Chemistry::Bond, includes basic objects and methods to describe molecules.
The core methods try not to enforce a particular convention. This means that only a minimal set of attributes is provided by default, and some attributes have very loosely defined meaning.

This is because each program and file type has different idea of what each concept (such as bond and atom type) means. Bonds are defined as a list of atoms (typically two) with an arbitrary type. Atoms are defined by a symbol and a Z, and may have 3D and internal coordinates (2D coming soon).

Chemistry Development Kit classes are Java utitility classes for ChemoInformatics and Computational chemistry, written in Java. They are developed constantly developed parallel to other projects that make use of them.
They are a complete re-write of the CompChem classes that were the basis of JChemPaint, a Java Editor for 2D chemical structures, and of JMDraw, a Java package for the graphical layout of 2D chemical structures.
The CDK project was started in September 2000 to replace the CompChem libraries used by JChemPaint, Jmol and SENECA. It no longer is in its initial stage, but is slowly getting a solid state.
The people involved in setting up the project are Christoph Steinbeck then at the Chemoinformatics Group at the Max Planck Institute of Chemical Ecology in Jena, as well as Egon Willighagen from the University of Nijmegen, The Netherlands, who is also involved with JChemPaint and many other Java Chemoinformatics programs, and Dan Gezelter from Notre Dame University, South Bend, USA, the initiator of Jmol, a 3D viewer and analyzer for molecules .
Now, the rewrite of these CompChem/CDK library classes do somehow effect all of our projects. All of our code relies to some extend on the so-called CompChem classes for computational chemistry.
Christoph Steinbeck started this chemistry library when he started programming SENECA, a system for Computer Assisted Structure Elucidation. It turned out that some of the code had design flaws that prevented others, like the authors of (Jmol) to use it.
Enhancements:
- This release consists of mostly some bugfixes, but also solves a few Java 1.4.2 compile problems and adds more functionality to the SMARTS parser.

Kemistry is a collection of chemical applications for the K Desktop Environment (release 3.x).

Originally the applications were distributed in a single source package, but currently every application is distributed in a standalone package. The available applications are

* KMolCalc - molecular weight and elemental composition calculator
* KemBabel - a file conversion program based on Open Babel
