Hi enztec,

it doesn't seem possible to create apl fns with apl_command or apl_exec directly using libapl This premiss seems wrong:
#include <apl/libapl.h>
// compile with: gcc libapl_test.c -L /usr/local/lib/apl -lapl -lstdc++ -o libapl_test
int
main(int argc, char * argv[])
{
init_libapl(argv[0], 0);
apl_exec( "TEXT ← ⊂ 'Z←A SUM B'" );
apl_exec( "TEXT ← TEXT, ⊂ 'Z←A + B'" );
apl_exec( "⎕FX TEXT" );
apl_command( ")FNS" );
apl_exec( "'⎕CR SUM:' (⎕CR 'SUM')" );
apl_exec( "1 SUM 2" );
}
which produces:
eedjsa@server68:~/apl-1.8/src$ ./libapl_test
SUM
⎕CR SUM: Z←A SUM B
Z←A + B
3
Or, even shorter:
apl_exec( "⎕FX 'Z←A SUM B' 'Z←A + B'");

Hi
it doesn't seem possible to create apl fns with apl_command or apl_exec directly using libapl
but i can successfully create a llibapl environment with fns and variables with the following setup and workaround
-
2 files fns.enz and fns.c
--
situation 1 : shows good fns created from fns.enz
/usr/local/bin/apl fns.enz
in apl workspace run
f1
f2 not created if it's fns definition header is commented in fns.enz but is created if uncommented
--
situation 2 :
/usr/local/bin/apl
in apl workspace run
)copy fns.enz
f1
f2 not created if it's fns definition header is commented in fns.enz but is created if uncommented
--
situation 3 :
g++ -O2 fns.c -o fns -L /usr/local/lib/apl -lapl
./fns gives my output below and creates fns1.xml fns2.xml and fns3.xml that can hopefully be of use for analysis of what is happening
in fns.c i can use apl_command(")copy fns.enz"); or apl_exec(")copy fns.enz"); with the fns definition header workaround to get working fns f1 and f2
but without the f1 and f2 fns definition headers in fns.c i get no f1 or f2 created
in the fns.enz ∇f1 and ∇f2 fns definition headers don't work as would hope/expect without the f1 and f2 function definition workaround in fns.c
as you can see in the fns.c after the )copy fns.enz if i do a workaround apl_exec("∇f1"); i get good fns f1 and f2
it seems the ∇f1 fns header doesn't work but the bodies of the fns in fns.enz and closing ∇ are in some 'buffer' and get put into the f1 fns when the f1 function header definitions workarounds is done in fns.c
the interesting thing is is that if i comment the f1 fns definition header in the fns.enz the fns are still created by the corresponding workaround line in fns.c but if i leave it uncommented (which is what it would be if it worked) when i run the correspinding fns header workaround in fns.c it gives the syntax error when run but doesn't prevent it from creating the good f1 fns - so it seems the f1 function definition header in fns.enz is doing something but not creating the fns.
i left the fns.enz f1 function header uncommented and the fns.enz f2 function header commented to show the difference
fns f2 is not created in situation 1 or situation 2 if it's fns definition header is commented in fns.enz but commenting does not affect it's creation in situation 3 (libapl) if f2 workaround fns definition header is used in fns.c
the correct order of the functions in fns.enz and the corresponding fns headers workarounds must be maintained to get proper working fns with the correct names
i have been using this workaround successfully but would love to know what is happening and see if there can be a fix
i have added 3 )save commands at 'strategic' points in fns,c to create the fns1.xml fns2.xml and fns3.xml in hope they give some information that can be used to analyze what is happening
thanks,
enztec
