StdEnv is the Standard Environment library that is standard included when you download a Clean system. It is available on all platforms Clean is running on.
The Standard Environment consists of the following library modules.
|StdArray||Basic array creation and modification functions.|
|StdBool||Basic boolean operations.|
|StdChar||Basic character, conversion, and predicate functions.|
|StdCharList||Justification, flattening, and splitting operations on character lists.|
|StdClass||Type constructor class definitions (PlusMin, MulDiv, Arith, IncDec , Enum, Eq, Ord)|
|StdDebug||Useful text output functions for tracing the execution of your program.|
|StdEnum||Is required when using .. expressions, such as [1,3..] the list of odd numbers.|
|StdEnv||Convenient module that imports all the other modules of the standard environment.|
|StdFile||Operations to open, modify, read, and close files. Most basic types can be read/written.|
|StdFunc||A number of functions of a general nature.|
|StdInt||Basic integer operations, plus bitwise operations.|
|StdList||Many standard and folklore functions on lists.|
|StdMisc||Two functions to terminate your program abruptly with or without a message.|
|StdOrdList||More functions on lists which elements are member of the Ord class.|
|StdOverloaded||Overloaded function definitions (e.g.: +,-,zero, *,/,one, toInt,toChar..., fromInt,fromChar ..., ln, log10..., sin,cos,tan...).|
|StdReal||Basic real (floating point) operations, plus logarithmical and trigonometrical functions.|
|StdString||String comparison, ordering, concatenation, and conversion functions.|
|StdTuple||Tuple and triple comparison, ordering, and selection functions.|
