5.1.82 listvar
Syntax:
listvar ( [package] )
listvar ( [package,] type )
listvar ( [package,] ring_name )
listvar ( [package,] name )
listvar ( [package,] all )
Type:
- none
Purpose:
- lists all (user-)defined names:
listvar(): all currently visible names except procedures in the current namespace,
listvar(type): all currently visible names of the given
type,
listvar(ring_name): all names which belong to the given
ring,
listvar(name): the object with the given name,
listvar(all): all names except procedures in the current and Top namespace.
The current basering is marked with a *. The nesting level of
variables in procedures is shown in square brackets.
package can be Current, Top or any other
identifier of type package.
Example:
| | proc t1 { }
proc t2 { }
ring s;
poly ss;
ring r;
poly f=x+y+z;
int i=7;
ideal I=f,x,y;
listvar();
==> // i [0] int 7
==> // r [0] *ring
==> // I [0] ideal, 3 generator(s)
==> // f [0] poly
==> // s [0] ring
listvar(r);
==> // r [0] *ring
==> // I [0] ideal, 3 generator(s)
==> // f [0] poly
listvar(t1);
==> // t1 [0] proc
listvar(proc);
==> // t2 [0] proc
==> // t1 [0] proc
==> // mathicgb_prOrder [0] proc from singmathic.so (C)
==> // mathicgb [0] proc from singmathic.so (C)
==> // create_ring [0] proc from standard.lib
==> // min [0] proc from standard.lib
==> // max [0] proc from standard.lib
==> // datetime [0] proc from standard.lib
==> // weightKB [0] proc from standard.lib
==> // fprintf [0] proc from standard.lib
==> // printf [0] proc from standard.lib
==> // sprintf [0] proc from standard.lib
==> // quotient4 [0] proc from standard.lib
==> // quotient5 [0] proc from standard.lib
==> // quotient3 [0] proc from standard.lib
==> // quotient2 [0] proc from standard.lib
==> // quotient1 [0] proc from standard.lib
==> // quot [0] proc from standard.lib
==> // res [0] proc from standard.lib
==> // groebner [0] proc from standard.lib
==> // qslimgb [0] proc from standard.lib
==> // hilbRing [0] proc from standard.lib
==> // par2varRing [0] proc from standard.lib
==> // quotientList [0] proc from standard.lib
==> // stdhilb [0] proc from standard.lib
==> // stdfglm [0] proc from standard.lib
==> // Float [0] proc from kernel (C)
==> // crossprod [0] proc from kernel (C)
LIB "polylib.lib";
listvar(Poly);
==> ? Poly is undefined
==> ? error occurred in or before ./examples/listvar.sing line 14: ` list\
