Lib/sys

Hint: if not defined pylibConfigIsolated, this module will call setlocale(LC_CTYPE, ""), a.k.a. changing locale to user's configure, just as CPython's initialization.

Note: the value is standalone for bare system

and haiku/netbsd appended with major version instead of "unknown". In short, this won't be "unknown" as Python does.

Procs

func exit(c: int) {....raises: [], tags: [], forbids: [].}
Source   Edit  
proc exit(s: PyStr) {....raises: [], tags: [], forbids: [].}
Source   Edit  
func exit(x: NoneType) {....raises: [], tags: [], forbids: [].}
Source   Edit  
func exit[T](obj: T)
Warning: this does not raise SystemExit, which differs Python's
Source   Edit  
proc getdefaultencoding(): PyStr {....raises: [], tags: [], forbids: [].}

Return the current default encoding used by the Unicode implementation.

Always "utf-8" in Nim

Templates

template executable(): PyStr
Note: when nimscript, this is path of Nim;

otherwise, it's the path of current app/exe.

Source   Edit  
template getsizeof(x): int
Source   Edit  
template getsizeof(x; default: int): int
may be used when sizeof(x) is a compile-error e.g. func sizeof(x: O): int{.error.} for O Source   Edit  
template rounds(fi: typeof(float_info)): int
not available when nimscript Source   Edit
