5.2.7 exportto

Syntax:

exportto( package_name , name );
exportto( package_name , list_of_names );

Purpose:

transfers an identifier in the current package into the one specified by package_name. package_name can be Current, Top or any other identifier of type package.

Note:

Objects defined in a ring are not automatically exported when exporting the ring.

Warning:

The identifier is transferred to the other package. It does no longer exist in the current package. If the identifier should only be copied, importfrom should be used instead.

Example:

proc p1 { int i,j; exportto(Current,i); intmat m; listvar(Current); exportto(Top,m); } p1(); ==> // Top [0] package Top (T) ==> // ::m [1] intmat 1 x 1 ==> // ::i [0] int 0 ==> // ::j [1] int 0 ==> // ::# [1] list, size: 0 ==> // ::p1 [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) package Test1; exportto(Test1,p1); listvar(Top); ==> // Top [0] package Top (T) ==> // ::m [0] intmat 1 x 1 ==> // ::i [0] int 0 ==> // ::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) listvar(Test1); ==> // Test1 [0] package Test1 (N) ==> // ::p1 [0] proc Test1::p1(); ==> // Test1 [0] package Test1 (N) ==> // ::m [1] intmat 1 x 1 ==> // ::i [0] int 0 ==> // ::j [1] int 0 ==> // ::# [1] list, size: 0 ==> // ::p1 [0] proc ==> // ** redefining m ( exportto(Top,m);) listvar(Top); ==> // Top [0] package Top (T) ==> // ::m [0] intmat 1 x 1 ==> // ::i [0] int 0 ==> // ::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) listvar(Test1); ==> // Test1 [0] package Test1 (N) ==> // ::i [0] int 0 ==> // ::p1 [0] proc
