There are several easier ways than using the FLI, all of which come down to using a double-float array to hold the values. The reason I'm asking is because I've been thinking about generalising my struct-of-arrays tool (whose purpose is to avoid this problem for implementations where it happens, amongst others). I'm assuming LW can't do this. --tim > On 6 Jan 2026, at 22:54, Alexey Veretennikov <[email protected]> wrote: > > Hi, > > I'm pretty sure you've tried it already but I would just define a fli C-struct, store a fli object allocated with fli:allocate-foreign-object for this struct as a class member and define a couple of accessor methods to access fields for the struct from your class, with the same naming conventions as the class accessors. > > BR, > /Alexey > > > On Tuesday, January 6th, 2026 at 20:54, Tim Bradshaw (as tfb at tfeb dot org) <[email protected]> wrote: > >> Are there any cases where LW can handle, for instance, unboxed doubles in structures (or CLOS instances). >> >> I haven't been able to persuade it to. >> >> --tim >> >> _______________________________________________ >> Lisp Hug - the mailing list for LispWorks users >> [email protected] >> http://www.lispworks.com/support/lisp-hug.html _______________________________________________ Lisp Hug - the mailing list for LispWorks users [email protected] http://www.lispworks.com/support/lisp-hug.html
