5.1.77 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
