5. The Standard Library

Som's standard library provides modules with values and types core to Som, both implemented natively or in C. Some of these modules provide functionality for accessing services "outside" of Som, such as I/O, while other modules implement trivial types such as List and Option.

Currently, Som's standard contains the following modules:

• io for file I/O
• list for the list type and related functions
• ops for aliasing builtin operators
• prelude for including basic features
• ptr for the pointer type and related functions
• str for the string type and related functions
• types for aliasing common primitive types

The standard library's runtime implementation is mostly in C and is distributed in the dynamic library libsom.so on Linux and MacOS and in som.dll on Windows. When using the standard library the final executable has to be linked to this library, which is normally done automatically by the compiler. Any library or program extending- or using Som's standard library outside of Som has to link to the dynamic library manually.
