Rather than assert that the types are correct, use the force type functions on the parameters:
ff, fk, fs, q2f, v2f, and the new fi, fl.
These functions have also been modified to ensure that the input type supports an implicit typecast to the target type and perform it, or emit ELSLInvalidType otherwise, rather than an assertion failure. fl in particular returns the original list if it isn't changed, or a copy if it is.
A couple bugs were found in testfuncs.py as a result, which have been fixed as well. A test has been added to ensure that the exception that caught these bugs remains in place.
The isxxxx functions are no longer necessary, so they are removed. Same goes for the painful cast handling process in foldconst, which was basically performing this task, and not necessarily well.
This approach is much more robust and should have been used since the beginning, but I didn't figure it out then.
Fix bug: add(Key, Key) is not valid.
Fix bug: llList2CSV was raising an exception always.
Fix bug in test program: llDumpList2String requires Unicode separator.
Patch test program to not output the passed tests.
- Scratch TODO item: Change shouldbeXXX to asserts.
- shoudlbeXXX(x) has been turned into assert isXXX(x). Affects lsl2json too.
- New base functions:
- compare (for == and !=)
- less (for <, >, <=, >=)
- minus() renamed to neg() for consistency. Affects testfuncs too.
- add() now supports key+string and string+key.
- Allow integers in place of floats. That has caused the addition of three utility functions:
- ff (force float)
- v2f (force floats in all components of a vector)
- q2f (force floats in all components of a quaternion)
Used everywhere where necessary.
Special care was taken in a few funcs (llListFindList and maybe others) to ensure that lists containing vectors or quaternions which in turn contain integer components, behave as if they were floats, because LSL lists can not physically hold integer values as components of vectors/quats.
This also fixes a case where if a large integer had more precision than a F32 (e.g. 16777217), the product/division would be more precise than what LSL returns.
- Fix bugs of missing F32() in some places (llRotBetween, llEuler2Rot).
- Some functions marked for moving in an incoming commit.
- llList2CSV marked with a warning that it is not thread safe. That's a future TODO.
- Document llListFindList better.
- Make llListStatistics Use a more orthodox method to return the result for LIST_STAT_RANGE, LIST_STAT_MIN, LIST_STAT_MAX.
- Make llAxisAngle2Rot use more precision from llVecNorm, by adding an optional truncation parameter in the latter.
- Change order of some F32(Quaternion(...)) to not force so much instancing.
- Bugfix: llVecNorm did not return a Vector.
- Parser and output modules are thoroughly tested and working.
- Most LSL immutable functions are working; some not tested; llJsonSetValue not implemented.
- Parser recognizes the following flags that alter syntax:
extendedglobalexpr: Allow full expression syntax in globals.
extendedtypecast: Allow full unary expressions in typecasts e.g. (float)~i.
extendedassignment: Enable the C assignment operators &=, ^=, |=, <<=, >>=.
explicitcast: Add explicit casts wherever they are done implicitly, e.g. float f=3; -> float f=(float)3;.
Of them, only extendedglobalexpr is useless so far, as it requires the optimizer to be working.
