Ezhil-Lang : எழில் - ஒரு தமிழ் நிரலாக்க மொழி; தமிழ் மாணவர்களுக்கு இது முதல்முறை கணிப்பொறி நிரல் ஏழுத உதவும் (Ezhil, is a fun Tamil programming language for K-12) Ezhil is a procedural language with dynamic types, like Ruby/Python. Ezhil has a pascal-like syntax, with for-end, while-end, if-elseif-else-end statements, break, continue and def-end for defining functions.

Ezhil language is implemented in a handwritten scanner and parser using the Python programming language. Latest version of Ezhil-Language is v0.6.

If you would like to tryout the code, all you need is a python interpreter, and the code from https://github.com/arcturusannamalai/Ezhil-Lang/archive/latest.zip

Interesting features include support for recursion, and an interactive interpreter. Ezhil supports a Turtle module for simple on-screen graphics, similar to LOGO language from 1960s.

Currently Ezhil language is under development, and a little rough around the edges. You may still try it out, by going to the git source repository,

$ cd ./ezhil-lang/

and then use one of the three modes,

1. Batch Mode
2. Interactive Mode
3. Web Mode

$ ./ez ./ezhil_tests/hello.n 
பதிப்பி "வணக்கம்!"
பதிப்பி "எழில் அழைக்கிறது"

வணக்கம்!
எழில் அழைக்கிறது

where you should see the output above. For usage, try,

$ ./ez --help
usage:  [-h] [-debug] [-stdin] [files [files ...]]

positional arguments:
  files

optional arguments:
  -h, --help  show this help message and exit
  -debug      enable debugging information on screen
  -stdin      read input from the standard input

$ ./ez
எழில் 1>> 1 + 5
6
எழில் 2>> பதிப்பி "வணக்கம்! எழில் அழைக்கிறது"
வணக்கம்! எழில் அழைக்கிறது
எழில் 3>> exit()

You can also run ezhil as a web service by launching the webserver, $ ./webserver.sh and open the webpage, http://localhost:8080 in google-chrome or firefox, to enter your program and evaluate it.

Ezhil Tamil programming Python package can be invoked from within the Python shell or IDLE on Windows, by simply typing,

>> import ezhil
>> ezhil.start()

But to do all of this, you need to build and install the Python packages from this source, by,

$ cd ezhil-lang/ && python setup.py build
$ cd ezhil-lang/ && python setup.py install

'''Rosetta Code''', the wiki platform for sharing standard algorithms, in many programming languages, now hosts several algorithms in Ezhil. You can find all of Ezhil programs there via http://rosettacode.org/wiki/Category:Ezhil
