5.1.68 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 in the current namespace:

• listvar(): all currently visible names except procedures,
• 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.

The current basering is marked with a *. The nesting level of variables in procedures is shown in square brackets.

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(all); → // i [0] int 7 → // r [0] *ring → // I [0] ideal, 3 generator(s) → // f [0] poly → // s [0] ring → // ss [0] poly → // LIB [0] string standard.lib listvar(); → // i [0] int 7 → // r [0] *ring → // I [0] ideal, 3 generator(s) → // f [0] poly → // s [0] ring → // LIB [0] string standard.lib 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 → // fprintf [0] proc from standard.lib → // printf [0] proc from standard.lib → // sprintf [0] proc from standard.lib → // intersect1 [0] proc from standard.lib (static) → // 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 → // quotient0 [0] proc from standard.lib (static) → // quot1 [0] proc from standard.lib (static) → // quot [0] proc from standard.lib → // res [0] proc from standard.lib → // groebner [0] proc from standard.lib → // stdhilb [0] proc from standard.lib → // stdfglm [0] proc from standard.lib
