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 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 ==> // 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 ==> // flintZ [0] proc from kernel (C) LIB "poly.lib"; listvar(Poly); ==> // Poly [0] package Poly (S,Poly) ==> // ::newtonDiag [0] proc from poly.lib ==> // ::subrInterred [0] proc from poly.lib ==> // ::id2mod [0] proc from poly.lib ==> // ::mod2id [0] proc from poly.lib ==> // ::content [0] proc from poly.lib ==> // ::lcm [0] proc from poly.lib ==> // ::rad_con [0] proc from poly.lib ==> // ::normalize [0] proc from poly.lib ==> // ::mindeg1 [0] proc from poly.lib ==> // ::mindeg [0] proc from poly.lib ==> // ::maxdeg1 [0] proc from poly.lib ==> // ::maxdeg [0] proc from poly.lib ==> // ::maxcoef [0] proc from poly.lib ==> // ::is_zero [0] proc from poly.lib ==> // ::freerank [0] proc from poly.lib ==> // ::kat_var [0] proc from poly.lib ==> // ::katsura [0] proc from poly.lib ==> // ::elemSymmId [0] proc from poly.lib ==> // ::elemSymmPoly [0] proc from poly.lib ==> // ::cyclic [0] proc from poly.lib ==> // ::substitute [0] proc from poly.lib ==> // ::hilbPoly [0] proc from poly.lib ==> // ::bino [0] proc from poly.lib (static)
