Jt is small sandbox static-typed language without garbage collector. So, welcome to reinvents powered language!

def double(a) {
    a + a;
}

Calculating а type when use double:

x = double(3);
> 6
y = double("ab"); # Stil doesn't work, shame on me
> "abab"

Also, imagine the great power of 4 basis types: integer, asci string, boolean and function!

Requires Python 2.7 or new 3+ already installed for development. That is install stuff, testing stuff and GYP project generator stuff. Not very bad C++11 compiler is a requirement too.

Code is almost cross-platform, except some debugging features. Currently testing platform:

• Windows 7 x64, MSVS 13 upd. 1 x86 compiler (Earlier compiler versions are not supported)

Call install.py to download prepared tool's binaries on Windows:

• GYP
• Ragel
• Bison
• LLVM assembler and interpreter

Install them manually on other platforms or stay tuned!

It's Windows-only yet, but you can still use it as hint.

Use GYP to generate project files for your favourite environment/IDE:

cd wintools
gyp ..\jt.gyp --depth=proj\vs13\ --generator-output=..\proj\vs13\tmp -f msvs -G msvs_version=2013

Regenerating lexer (Ragel) and parser (bison) files after changing grammar:

cd wintools
gen.bat

Or run something like this:

cd wintools
Ragel -o ../src/lexer_gen.cpp ../src/lexer.rl
set BISON_PKGDATADIR=bison/
bison -d -o ../src/parser_gen.cpp ../src/parser.y
