Free hardest language to learn software for linux

Plone Language Tool is a product which allows you to set the available languages in your Plone site.
PloneLanguageTool allows you to set the available languages in your Plone site, select various fallback mechanisms, and control the use of flags for language selection and translations.
When installed, a new Plone control panel action will allow you to select various language options, such as the default and list of allowed languages.
PloneLanguageTool is shipped with Plone beginning in version 2.1 and up.
Enhancements:
- Bug fix release included in Plone 2.5.2.

Natural Language Toolkit is a suite of Python libraries and programs for symbolic and statistical natural language processing. NLTK includes graphical demonstrations and sample data.
It is accompanied by extensive documentation, including tutorials that explain the underlying concepts behind the language processing tasks supported by the toolkit.
Documentation:
A substantial amount of documentation about how to use NLTK is available from the nltk home page:
< http://nltk.sourceforge.net >
In particular, the NLTK home page contains three types of documentation:
- Tutorials teach students how to use the toolkit, in the context of performing specific tasks. They are appropriate for anyone who wishes to learn how to use the toolkit.
< http://nltk.sourceforge.net/tutorial/ >
- The toolkits reference documentation describes every module, interface, class, method, function, and variable in the toolkit. This documentation should be useful to both users and developers.
< http://nltk.sourceforge.net/ref/nltk.html >
- A number of technical reports are available. These reports explain and justify the toolkits design and implementation. They are used by the developers of the toolkit to guide and document the toolkits construction. Students can consult these reports if they would like further information about how the toolkit is designed and why it is designed that way.

Enhancements:
Code (major):
- changed package name to nltk
- import all top-level modules into nltk, reducing need for import statements
- reorganization of sub-package structures to simplify imports
- new featstruct module, unifying old featurelite and featurestructure modules
- FreqDist now inherits from dict, fd.count(sample) becomes fd[sample]
- FreqDist initializer permits: fd = FreqDist(len(token) for token in text)
- made numpy optional
Code (minor):
- changed GrammarFile initializer to accept filename
- consistent tree display format
- fixed loading process for WordNet and TIMIT that prevented code installation if data not installed
- taken more care with unicode types
- incorporated pcfg code into cfg module
- moved cfg, tree, featstruct to top level
- new filebroker module to make handling of example grammar files more transparent
- more corpus readers (webtext, abc)
- added cfg.covers() to check that a grammar covers a sentence
- simple text-based wordnet browser
- known bug: parse/featurechart.py uses incorrect apply() function
Corpora:
- csv data file to document NLTK corpora
Contrib:
- added Glue semantics code (contrib.glue, by Dan Garrette)
- Punkt sentence segmenter port (contrib.punkt, by Willy)
- added LPath interpreter (contrib.lpath, by Haejoong Lee)
- extensive work on classifiers (contrib.classifier*, Sumukh Ghodke)
Tutorials:
- polishing on parts I, II
- more illustrations, data plots, summaries, exercises
- continuing to make prose more accessible to non-linguistic audience
- new default import that all chapters presume: from nltk.book import *
Distributions:
- updated to latest version of numpy
- removed WordNet installation instructions as WordNet is now included in corpus distribution
- added pylab (matplotlib)
Enhancements:
Code:
- changed nltk.__init__ imports to explicitly import names from top-level modules
- changed corpus.util to use the rb flag for opening files, to fix problems reading corpora under MSWindows
- updated stale examples in engineering.txt
- extended feature stucture interface to permit chained features, e.g. fs[F,G]
- further misc improvements to test code plus some bugfixes
Tutorials:
- rewritten opening section of tagging chapter
- reorganized some exercises

Arena Scripting Language is a light-weight scripting language. The language uses a syntax and library similar to that of ANSI C, but adds automatic memory management and runtime polymorphism on top of that.
Main features:
- syntax similar to ANSI C
- standard library similar to ANSI C
- automatic memory management
- runtime polymorphism
- support for exceptions
- support for anonymous functions
Enhancements:
- This release changes the system() library function to return the raw exit status as given by the operating system.

Short Markup Language is an alternative XML notation that is a character by character equivalent with XML.
Short Markup Language covers all legal XML constructs, including processing instructions, doctype declarations, internal DTD subsets and namespace declarations.
Currently SML-to-XML and XML-to-SML converters have been implemented. The converters are based on efficient JavaCC parsers, and can be run from the command-line run or an Ant-task.
Short Markup Language is an open-source project, published under the GNU General Public Licence.
Enhancements:
- First release includes SML to XML and XML to SML converters in an easy to use executable jar.

Website META Language is a free and extensible Webdesigners off-line HTML generation toolkit for Unix, distributed under the GNU General Public License (GPL v2). Website META Language is written in ANSI C and Perl 5, built via a GNU Autoconf based source tree and runs out-of-the-box on all major Unix derivates.
It can be used free of charge both in educational and commercial environments. WML consists of a control frontend driving up to nine backends in a sequential pass-oriented filtering scheme. Each backend provides one particular core language. For maximum power WML additionally ships with a well-suited set of include files which provide higher-level features built on top of the backends core languages.
While not trivial and idiot proof WML provides most of the core features real hackers always wanted for HTML generation.
Enhancements:
- Building of the package on Cygwin was fixed.
- Some vendor patches were integrated.

File Selection Language (FSL) is a descriptive language for file selection. File Selection Language is used to selectively pick files from a directory structure.
FSL is useful for selective backups, for instance. FSL uses glob patterns as the basic building block.
For fine-tuning the selection, inclusion/exclusion rule combinations and conditional expressions are available. File size and modification date can be used in expressions.
Main features:
- FSL can be used with a command line tool (fsltool) or, for Python programmers, with a programmable interface. For the Python interface, see the documentation of Interpreter.py.
- Several FSL rule files can be combined in a cascading manner similar to CSS. The effect is the same as if the rule files were pasted into a single file.
- Support for both Windows-like and Unix-like paths.
- Strict parse-time type checking to catch as many errors as possible before run-time. For example, you cant say EACH f IF size(5) > 1000 because function size expects filename argument.

Open Dice Language project is a language for describing dice rolls.

Open Dice Language is a language for describing dice rolls.

The language is nearly identical to what you see in most role-playing game texts (e.g., "1d20"). It provides several interfaces to the language.

To run in CLI interface mode:

# pushd $ODL_HOME
# java -jar ODL.jar

To run as Widget:

build using `ant widget`
widget is now installed in users widget directory
