INTRODUCTION

What is cs2n?

cs2n is a tool for converting C# sources into Nemerle sources. It is available in standard Nemerle distribution and is included in our binary packages.

Requirements

To compile cs2n by hand you need to have antlr installed - ANother Tool for Language Recognition, which is used to create lexer and parser. Nemerle main configure script will detect it automatically and include cs2n in standard compilation process.

Compiling

Enter into nemerle/tools/cs2n/ directory. To compile type:

• make

Running

To convert your sources type:

• cs2n input_file.cs

Nemerlish options to cs2n

-nemerlish-function-parameters

Alias: -nfp

Drops "mutable" modifier from function parameters.

cs2n behavior:

Code

 
public void MyMethod (string s)
{
...
}

is translated to:

 
public MyMethod (s : string)
{
...
}

instead of:

 
public MyMethod (mutable s : string)
{
...
}

-nemerlish-default-value

Alias: -ndv

Uses "null", instead of DefaultValue macro for variable initializer.

cs2n behavior:

Code

 
SomeClass c;

is translated to:

 
mutable c = null;

instead of:

 
mutable c = Nemerle.Extension.DefaultValue (SomeClass);

Declarations of types: float, double, int, uint, long, ulong, byte, sbyte, short, ushort,decimal are initialized with 0. Char is initialized with '\0'.

-nemerlish-foreach

Alias: -nf

Drops ':> type' from foreach statement.

cs2n behavior:

Code

 
foreach (string s in collection)
...

is translated to:

 
foreach (s in collection)
...

instead of:

 
foreach (s :> string in collection)
...

-nemerlish

Alias: -n

Enables all -nemerlish-* flags.
