This is a guide for people with experience in C or a similar language. The general tutorials can be found here:

The manual provides a more or less complete overview of the language:

### Structs - Tuples and Objects
|
|
|
|
Tuples and Objects in Nimrod are kind of like structs in C, but not really.
|
|
|
|
### Interfacing C and Nimrod
|
|
|
|
See [Foreign Function Interface](http://nimrod-lang.org/manual.html#foreign-function-interface)
|
|
|
|
### Cheat Sheet
|
|
Note: Code examples are not exactly one-to-one, there may be subtle differences in the semantics. See comments.
