* system refactor, move out 600 lines * compilation, slice, backwardsindex, misc_num moved out of system * some procs/types moved into arithmetics, basic_types * system no longer depends on syncio * some procs moved around to fit with their surroundings * make exceptions an import, old ops to misc_num * move instantiationInfo back * move back nim version, fix windows echo * include compilation * better docs for imported modules, fix unsigned ops also remove ze, ze64, toU8, toU16, toU32 with nimPreviewSlimSystem * fix terminal * workaround IC test & weird csize bug, changelog * move NimMajor etc back to compilation, rebase for CI * try ic fix * form single `indices`, slim out TaintedString, try fix IC * fix CI, update changelog, addQuitProc * fix CI * try fix CI * actually fix CI finally hopefully * Update lib/system/compilation.nim Co-authored-by: ringabout <43030857+ringabout@users.noreply.github.com> * update kochdocs * hopefully fix csize uses for slimsystem * fix tquit Co-authored-by: ringabout <43030857+ringabout@users.noreply.github.com>

|
|
|
|
OverflowDefect* = object of ArithmeticDefect ## \
|
|
## Raised for runtime integer overflows.
|
|
##
|
|

|
## Raised for invalid memory access errors
|
|
AssertionDefect* = object of Defect ## \

## Raised if an array index is out of bounds.
|
|
|
|
FieldDefect* = object of Defect ## \
|
|
## Raised if a record field is not accessible because its discriminant's

|
|
ObjectAssignmentDefect* = object of Defect ## \
|
|
## Raised if an object gets assigned to its parent's object.
|
|
ObjectConversionDefect* = object of Defect ## \
|
|
## Raised if an object is converted to an incompatible object type.
|
|
## You can use `of` operator to check if conversion will succeed.
|
|
FloatingPointDefect* = object of Defect ## \
|
|
## Base class for floating point exceptions.
|
|
FloatInvalidOpDefect* = object of FloatingPointDefect ## \
|

##
|
|
## Raised by `0.0/0.0`, for example.
|
|
FloatDivByZeroDefect* = object of FloatingPointDefect ## \
|
|
## Raised by division by zero.
|
|
##
|

|
|
##
|
|
## The operation produced a result that exceeds the range of the exponent.
|
|
FloatUnderflowDefect* = object of FloatingPointDefect ## \
|
|
## Raised for underflows.
|
|
##
|
|
## The operation produced a result that is too small to be represented as a

|
|
## Raised for inexact results.
|
|
##
|
|
## The operation produced a result that cannot be represented with infinite
|
|

|
|
##
|
|
## **Note**: Nim currently does not detect these!
|
|

|
|
NilAccessDefect* = object of Defect ## \
