| Post subject: | How to check if a library is loaded? |
I would like to automatically check if a library is loaded. One idea was to use "listvar(package)", but this seems to print such a list to the screen, rather than return an object that I can search through. I think this used to be possible in Singular 2 with "string(LIB)", but that doesn't seem to be the case anymore. Does anybody know how to do this? |

In Singular-2.x you could look up the global variable LIB (of type string) and search for the library using the command find e.g. Code: > LIB; standard.lib > find("LIB","standard.lib"); 1 > find(LIB,"ring.lib"); 0 > LIB "ring.lib"; // ** loaded /usr/o0/Singular-203/sparcv7-sun-solaris2.7/Singular/2-0-3/LIB/ring.lib (1.17.2.1,2002/02/20) // some more output here > LIB; standard.lib,ring.lib,general.lib,matrix.lib,random.lib,poly.lib,inout.lib > find(LIB,"ring.lib"); 14 This does no longer work, as LIB is now the string "_". In Singular-3.x you have to use the command defined with capitalized first letter of the library (without the trailing .lib): Code: > defined(Sing);
0 > LIB "sing.lib"; // ** loaded /LIB/sing.lib (1.30,2006/08/02) > defined(Sing); 1 |
